trade in intermediate goods and services exceeds that of commodities and finished goods.

Unilateral trade liberalization and lower trade barriers made possible by free trade agreements

(FTAs) and the creation of the World Trade Organization (WTO) have spurred GVC growth.
Technology advancements and new internet-enabled services that lower costs and provide seamless connections around the
world have also been a major factor. Consequently, companies and countries can focus on comparative advantages and
specialize in different products and services within value chains, opening economic opportunities and new markets for small
businesses and developing countries.
Despite the growing presence of GVCs in the global economy, recent events have highlighted the potential risks and
vulnerabilities of GVCs, particularly those that are concentrated in a particular region or reliant on a single supplier.
Worldwide natural disasters, emergencies, and other policy-driven circumstances, such as the Coronavirus Disease 2019
(COVID-19) pandemic, have shown that GVC links integrate and create interdependence between economies, which can
leave companies vulnerable to external shocks, including interruptions in other countries. At the same time, interdependence
can create broader economic growth and strengthened relationships among nations. After a period of rapid globalization
through the 1990s and early 2000s, the growth of GVCs has slowed in recent years.
Concerns about U.S. value chains and the ongoing COVID-19 pandemic have raised questions about potential risks that
GVCs may pose for particular economic sectors, the economy more generally, and, depending on the product and degree of
external dependencies, national security. For example, recent events have shown that certain sectors, such as medical supplies
and information technology and communications equipment, are susceptible to risks if the production of key components is
concentrated in one country or controlled by one company. Some companies are seeking to diversify their supplier base
across countries and regions, in part to increase their resilience and to lower their risk exposure. Some analysts foresee
greater shifts in the future. To mitigate risks and vulnerabilities, companies may (1) rethink their business models and seek to
build in redundancies for resilience, (2) focus more on shorter local or regional value chains, and/or (3) utilize emerging
technologies to lower and diversify risks and costs. These shifts will likely vary across industry sectors, depending in part on
the location and availability of suppliers and customers, as well as U.S. and foreign trade and investment policies.
In response to the risks described above, many policymakers, companies, and other stakeholders are reevaluating the role of
GVCs in the economy. Several factors influence the formation and configuration of GVCs, including new and updated FTAs
(e.g., the U.S.-Mexico-Canada Agreement), along with changes in import policies, rules of origin, export controls, investment
regimes, and labor and manufacturing costs. These factors provide Congress with multiple levers to influence corporate
decisions. Some U.S. and foreign policymakers have introduced legislation and other measures to incentivize, or in some
cases force, companies or certain industries to shorten their value chains and increase domestic production. Such measures
could affect the accessibility, quality, and price of goods sought by U.S. buyers.

Global Value Chains: Overview and Issues for Congress

Introduction
Global value chains (GVCs) are an important aspect of current international trade and investment.
Such chains disaggregate production processes into discrete stages in various locations around the
globe to achieve efficient production. Since the 1990s, powered by trade liberalization and
advances in services and technology, companies have increasingly structured international trade
around global value chains. Global commerce has grown more complex and involves less
bilateral trade in final goods and services between two countries and more vertically integrated
trade, often across many borders. As a result, to participate in the global economy today, countries
no longer need to specialize in the full production of final goods and services. Instead,
participating countries can focus on specific tasks and business functions in which they have a
comparative advantage within a production process. For instance, design, engineering, and
branding of a product may take place in the United States with managers overseeing assembly in
Asia, with inputs that were manufactured in Asia, Latin America and Europe.
GVCs are used by firms of all sizes and across various industrial and commercial sectors. Some
are relatively simple, involving a few players, while others are more complex, with partners and
their suppliers supporting a multilayered GVC structure. Smaller firms participating in larger
GVCs may not even know their ultimate end customer—a lack of transparency that may leave
partners or firms further up the value chain vulnerable to sudden shifts or external events.
Overall, GVCs are seen as beneficial in increasing trade and investment globally and ultimately
leading to net economic growth. U.S. firms and their workers play leading roles in managing
GVCs of multinational firms as well as participating as suppliers and partners in U.S. or foreign
companies’ GVCs. At the same time, the globalization of production has raised questions among
some U.S. policymakers and challenged certain long-held perceptions about the impact and
effectiveness of certain federal policies, including those related to international trade such as free
trade agreements or import rules.
For many observers and analysts, the Coronavirus Disease 2019 (COVID-19) pandemic
demonstrates how GVCs have grown more complex and global in scope. It also highlights the
risks of relying on certain global value chains, in particular those with supply and distribution
channels that are, on one hand, expansive or, on the other, highly concentrated and that use just-
in-time manufacturing systems with minimal stockpiles. Shortages of intermediate and final
goods during the pandemic have illustrated the resilience and robustness of some supply chains
and the vulnerabilities and weaknesses of others.
Some policymakers, corporate leaders, and other stakeholders are evaluating current U.S. GVCs’
patterns and policy aspects. In doing so, they are examining the costs, feasibility, risks, domestic
capacity, and potential options to potentially shift or reconfigure some of these supply chains.
Some Members of Congress and the Trump Administration have sought to incentivize U.S.
domestic production to restore or “reshore” production to the United States, lessen U.S. reliance
on certain imports, and diversify U.S. production bases geographically, particularly away from
China. Some firms are seeking greater diversification to address certain unintended consequences
that have become apparent during COVID-19, including with respect to the predominant role of
China in certain GVC inputs.
This report provides an overview of GVCs, their potential costs and benefits including their
emergence and role in the economy, explores possible vulnerabilities associated with GVCs, and
identifies issues and options for companies and policymakers to reduce related risks and
potentially strengthen the domestic economy.

Economics of GVCs
U.S. trade has become increasingly complex, and the changing dynamics of the global economy
pose both opportunities and challenges for the United States. In the past, U.S. firms tended to
source most or all of their production in the United States, using inputs and raw materials that
were made or sourced domestically. The reasons for this insularity are largely historic and can be
traced back to the early development of the U.S. economy. The Commerce Clause of the U.S.
Constitution promoted interstate commerce by ensuring that individual state economies would
unite into a single national market that allowed for the free movement of goods, capital, and labor
anywhere within the nation. As the domestic economy developed over time, the U.S. government
intervened to incentivize or subsidize transportation and communication infrastructure (e.g.,
roads, railways, ports, and eventually airports), regulate business activity, protect intellectual
property, and encourage innovation. This large, unified market gave U.S. businesses a distinct
advantage in global markets, since they could spread their operations across multiple state
markets and take advantage of concentrations of consumers, natural resource endowments, and
different labor skills and wages—all while operating under a common, shared federal regulatory
system.
The paradigm under which many U.S. businesses operated for much of the 19th and early to mid-
20th centuries was based on geographical boundaries, country-to-country trade of final goods, and
vertically integrated, domestic manufacturing. The process of opening up economies, removing
barriers to trade and investment, and deepening economic integration and interdependence,
however, began to introduce fundamental changes to the U.S. and global economies. The growth
of new competitors, many of them emerging market and developing economies, contributed—and
in many ways continue to contribute—to changes in the direction and composition of
international trade and investment, as well as to the redistribution of power within the global
economy. Although the present period of economic globalization began after World War II, these
trends accelerated in the 1980s with China’s economic reforms and opening-up, and intensified
even further in the 1990s following the end of the Cold War (Figure 1)

Production Beyond the Pandemic
, June 2020.
Notes: Trade is global exports of goods and services. GVC share of trade is proxied by the share of foreign
value added in exports, based on the UNCTAD-Eora GVC database. The underlying FDI trend is an UNCTAD
indicator capturing the long-term dynamics of FDI by netting out fluctuations driven by one-off transactions and
volatile financial flows.
In particular, three revolutionary changes have helped to redefine business production methods
and facilitate the growth of GVCs: (1) technological developments that reduced the costs of
communication and transportation; (2) the rise of business management strategies that
emphasized core competencies and just-in-time production;1 and (3) the breaking down of trade
and investment barriers across the globe and the establishment of an open, transparent, and non-
discriminatory rules-based global trading system. This was accomplished through a wide range of
international institutions and agreements, including the General Agreement on Tariffs and Trade
(GATT) in 1947, and its successor, the World Trade Organization (WTO) in 1995. These changes
contributed not only to the expansion of world trade and cross-border investment flows, but also
to a dramatic increase in the world supply of labor, along with a shift in economic activity—
particularly manufacturing—from developed to emerging markets. At the same time, developed
economies became increasingly specialized in technologically advanced industries and high value
added tasks (e.g., research, design, and engineering). Underlying all these changes has been a

1 The idea of core competencies is that they represent the true sources of competitive advantage and that such
competencies should be the focus of firm effort. All other activities could be outsourced. See G. Hamel and C.K.
Prahalad. “The Core Competence of the Corporation,” Harvard Business Review, vol. 68, no. 3, 1990, pp. 243-244. A
just-in-time production system is the coordinated manufacture of components or products so that materials are received
or produced at the precise time and in the exact quantity to meet the demand of the customer or the next operation in an
assembly process. This coordination reduces costs by eliminating the need to hold large inventories of parts and
product, and allows for defects in parts to be corrected before being incorporated into a product. Related to these
changes is the steady improvement in product quality, risk minimization, flexibility in meeting consumer demand, and
profit maximization over a supply chain rather than for each entity within that chain.

period of relative stability in the international order, coupled with the absence of conflict on a
global scale that might have threatened production and international shipping.
The United States, in particular, was a driving force in breaking down trade and investment
barriers across the globe and constructing the open and rules-based global trading system that has
enabled GVCs to proliferate. While some workers and producers have experienced a
disproportionate share of the short-term adjustment costs (e.g., through increased global
competition or job losses) associated with the growth of GVCs, the net payoff to the United
States and the global economy from GVC participation is estimated to be substantial. For
example, stronger linkages to the global economy force U.S. industries and firms to focus on
areas in which they have a comparative advantage, provide them with export and import
opportunities, enable them to realize economies of scale, and encourage knowledge sharing and
innovation. In addition, households have been able to enjoy lower product prices and a broader
variety of goods and services—some of which may not be produced domestically.
GVCs also support a broad range of widely dispersed service-sector jobs in such areas as
transportation, sales, finance, marketing, insurance, law, and accounting. Over the years, studies
have shown that GVCs can boost growth, create better and higher paying jobs, and reduce
poverty, especially when appropriate environmental, social, and governance policies are in place.2
According to one analysis, trade-dependent jobs in the United States increased by 180% (from
14.5 million to 40.6 million) between 1992 and 2018.3 Some job losses associated with GVCs,
however, may be highly concentrated in certain industries or geographical regions.
These developments, and the linkages they have formed, have blurred the distinction between
exports and imports as strictly domestic or foreign corporate activities. The globally-dispersed
nature of production has increased the level of trade required to produce many final products in
both developed and emerging markets. Trade in intermediate goods and services is associated
with productivity gains in domestic industries, increased sophistication of production, and higher
overall economic activity.4 However, trade in intermediates also means that some imports have
become essential inputs into the production of exports. As a result, products are often traded
across borders multiple times, complicating the interpretation of bilateral trade balances. Within
this context, understanding who benefits and loses from global trade and GVCs has become
increasingly difficult.
Although a data time lag prevents analysts from developing a current understanding of GVC
trends, some studies indicate that the growth of certain GVCs has slowed in recent years. For
example, the WTO notes that between 2000 and 2007, GVCs, “especially complex ones,
expanded at a faster rate than GDP.... [There was] some retrenchment of GVCs [during the global
financial crisis], followed by quick recovery (2010-2011), but since then growth has mostly
slowed. However, most recent data for 2017 show that complex GVCs grew faster than GDP.”5

Global Value Chains: Overview and Issues for Congress

Role of Services and Technology in GVCs
Trade in services and advances in information and communications technology (ICT) have
enabled the growth of GVCs. In turn, GVCs have expanded and redefined the role that services
play in international trade. Intermediate services, though often hidden and embedded within a
value chain, facilitate GVCs. Such services include transportation and distribution, research and
development (R&D), and design and engineering, as well as business services, such as legal,
accounting, marketing, and financial services. In a GVC, partners involved in each of these areas
can be located in widely different places. Innovations in communications, financial services, and
transport have been key to the growth and dispersion of value chains.
For example, transportation services that move intermediate and finished goods along supply
chains are essential to GVCs. The 20th-century shift in the maritime industry to transporting
goods in standardized containers lowered costs, reduced the time ships spent in harbors, increased
efficiency, and allowed for economies of scale—all leading to a growth in the volume and
reliability of international trade by sea. Today, about 80% of the world’s trade is transported by
container-based shipping.6 The growth in air services, both via cargo planes and passenger planes
that carry cargo, has also enabled GVCs to expand, particularly those that rely on fast delivery of
continually changing and updating products or certain perishable goods.
Recent innovations and ICT advancements have enabled more complex supply chains, increasing
the efficiency, and potential vulnerability, of GVCs. A 2019 report by multilateral organizations
stated, “GVCs and digital technology cannot be separated and dealt with as independent trends
and forces.”7 According to one analysis of small and mid-sized enterprises in Asia, digital tools
reduce export costs by 82% and transaction times by 29%.8
In particular, analysts point to digital platforms, automation, the Internet of Things (IoT), artificial
intelligence (AI), and advances in data processing and analytics as key forces reducing cross-
border transaction costs and promoting international trade.9 Digital platforms, for example, power
data exchanges, digital communications, and e-commerce—all of which enable large and small
companies to reach suppliers and manufacturers abroad and to receive direct, immediate feedback
on customer demand and partner capacity. At the early stages of the value chain, R&D, design,
engineering, and marketing may use advanced analytics, job-specific or fit-for-purpose software,
and technology platforms to accomplish their jobs. Some of these functions may be conducted at
headquarters or in the home market, while others may be outsourced to vendors abroad, all
connected via the internet.
Some analysts refer to the digitization and reorganization of supply chains using new emerging
and advanced technologies as “Supply Chain 4.0” (see text box).10 A recent study suggests that
changes enabled by Supply Chain 4.0 could lead to an estimated 65% labor-efficiency increase

and a 30%-40% unit-cost reduction for manufacturing overhead.11 Automated processes and
analytics can improve supply chain efficiency. Blockchain is one such emerging technology.12
Firms may use blockchain for logistics management to link different suppliers and partners and to
expedite and monitor the movement of goods along a supply chain. For example, sensors
connected to IoT devices allow manufacturers and shipping companies to track products, both
intermediate and final goods, as they travel within a factory or across the globe. Firms that
analyze large data sets with AI to predict demand can then efficiently move and allocate
resources, ramping production up and tamping it down or making other adjustments, such as
switching suppliers or cargo routes, in response to specific events or changing circumstances.
Digitization allows firms to build resiliency by more easily replicating processes and storing data
in multiple locations.
Although the use of many digital technologies is widespread, the applications of other advanced
technologies continue to evolve impacting how companies organize and manage new and existing
GVCs. Companies are adapting and incorporating these emerging technologies into their routines
and systems at different speeds, varying by sector and corporate culture. The COVID-19
pandemic and related economic challenges have spurred some firms to increase investment in
data and analytics to better understand utilization and performance of their GVCs. According to
one report, annual spending by global manufacturers on data management, analytics, and other
advanced capabilities is expected to grow to nearly $20 billion by 2026, compared with $5 billion
in 2020.13
As companies rely on technology to inform business decisions and manage GVCs, securing ICT
systems becomes essential, whether to protect intellectual property, private communications, or
proprietary data, or to minimize disruptions from cybersecurity incidents. Implementing an
effective ICT supply chain risk-management system based on best practices can help minimize
risks. Seeing a need for such guidance, the Cybersecurity and Infrastructure Security Agency
(CISA) has published multiple resources on ICT supply chain risk management.14
Example of Supply Chain 4.0
Some analysts point to technology as not simply enabling the use of supply chains, but as revolutionizing the ways
supply chains traditionally work. For example, in the graphic below, a firm manages end-to-end performance,
gathering data from multiple sources to build transparency along all points of the supply chain. The firm uses
connected and advanced technologies to forecast supply and demand; automate planning and decision-making;
continuously adjust and track factory production, warehousing, transportation and delivery; and communicate with
partners and end customers. The inputs and points of the supply chain are not location-specific and could be
situated within the same geography or across multiple geographies, such as different regions within one country or
dispersed throughout various countries.

Although digitization has enabled GVCs to develop and expand, some industry experts are
turning to technologies such as robotic automation and 3D printing to reshore or shorten existing
GVCs. By digitizing processes that increase efficiencies and reduce labor requirements and costs,
some firms may be able to consolidate sprawling supply chains into fewer partners or
geographies, or to reshore certain value chain functions. One firm estimates that 40% of
companies globally are increasing their use of automation to gain greater efficiency, speed, and
control of their supply chains while cutting waste, labor needs, and operating costs.15 Increasing
automation, however, raises broader concerns about potential job losses and worker
displacement.16
Business Decisions and the Public Interest
In a world of GVCs, U.S. national and business interests may coincide—and at times conflict—
with one another. A firm’s headquarters may be located in the United States, but its production
networks may be global. Firms generally attempt to maximize profits and efficiency across the
entire supply chain, not just in the domestic portion of it. In addition, profits may accrue to the
U.S. parent company, but many of the supplier, production, and assembly jobs may be abroad.

Global Value Chains: Overview and Issues for Congress

Whether a policy that is good for U.S. businesses is also good for the United States as a whole
depends on a number of factors, including the:
 distribution of profits;
 composition and degree of specialization of the workforce;
 extent to which the value generated by segments of the value chain takes place in
the United States; and
 effect that supply chain relationships have on the amount and composition of
U.S. trade and jobs.
When deciding whether to establish or become part of a supply chain, firms must contemplate
several questions. First, what are the core competencies of the firm? What tasks or business
functions should the firm carry out domestically or regionally, and what can and should be
contracted out or performed globally? In addition, where should production, assembly, and
packaging take place, and how can any of these decisions help overcome the challenges in
accessing major markets abroad? Finally, should the firm invest in manufacturing facilities and
own the process or rely on partners?
The answers to these questions help determine the shape, location, and operation of supply
chains, as well as the interconnections within them. In addition, production decisions are affected
by cost and risk calculations, economic conditions, government policies, and regulations. For
example, in deciding whether to assemble a product abroad, firms consider various risks, such as
exchange rate fluctuations, inflation, shipping disruptions, political turmoil, natural disasters,
regulatory uncertainty, terrorism, trade barriers, and the ability to control and ensure product
quality and safety.
Small and Mid-Sized Enterprises (SME), GVCs, and Trade Finance
According to the World Trade Organization (WTO) and International Finance Corporation (IFC) of the World
Bank, up to 80% of trade is financed by credit or credit insurance, but the availability of finance varies across
regions.17 GVCs are often the easiest path for SMEs to grow and reach outside markets, especial y for those
located in developing countries. Many SMEs rely on trade finance to ensure their cash flow and engage in
international trade. For example, a large importer may use its bank to provide a letter of credit to an SME
exporter’s bank that pays the exporter once it shows documents (e.g., bil of lading) that prove the shipment
occurred. By introducing banks as third parties, trade finance reduces the risk for both the importer and the SME
exporter.
Research shows that default and loss rates for trade finance are generally low.18 Despite these low rates, the
availability of trade finance has been falling, especial y in developing markets. The WTO/IFC report shows the
unmet demand for trade finance is $1.5 tril ion annually.
Local banks rely on international correspondent banks to confirm and clear payments. However, in recent years,
many large banks have been cutting their correspondent banking relationships in an effort to de-risk. Large
international banks cite strict regulatory and compliance requirements (e.g., anti-money laundering and customer
due diligence rules) that increase costs and deter them from offering trade finance services in perceived risky
markets.19 To address the gap in trade finance availability, the WTO and other institutions have begun conducting
capacity building and training to disseminate guidance and best practices in an effort to lower the risk profiles of
local banks in developing countries. Furthermore, some banks and brokers are using new technologies like
blockchain to extend trade finance services to SMEs and to build new customer relationships. The shift to greater

use of technology has become especial y important to extend trade finance and supply chain credit during the
COVID-19 pandemic, as restrictions limit in-person interactions and economic hardship increases the importance
of providing credit to bridge gaps.
Reconsidering Traditional Statistics of International Trade
The growth of GVCs, intra-firm trade, and trade in intermediate goods means that traditional
accounting methods may not fully reflect the source of inputs used in producing goods and
services, a limitation that may ultimately distort trade data tallied using such methods.20 As more
products are effectively made globally, concepts such as country of origin and bilateral trade
imbalances may take on different meaning.21 This shift makes it increasingly difficult to
understand and interpret the implications of trade data trends for the U.S. economy. In addition,
conventional data that often drive policy discussions may underestimate trade in services, because
the data do not attribute any portion of the traded value of manufactured and agricultural products
to services inputs. As mentioned above, intermediate services such as transportation and
distribution, R&D, and design and engineering are embedded within a value chain as inputs and
thus are often not visible in the data. Moreover, these data are not disaggregated enough to
identify trends in GVCs or their impact on the U.S. economy.
China is an example of this phenomenon. Since opening up its economy to global trade and
investment in the 1980s, China has emerged as a major manufacturing/production center for
GVCs (see “Regional Specialized Value Chains: ICT Goods”). Because of China’s large pool of
relatively low-cost labor, in the 1990s many export-oriented multinational corporations (MNCs)
moved production from other countries (primarily in Asia) to China. This production typically
involved importing key components and intermediate goods for minimal processing in China
before re-exporting them. The value-added gains that occurred in China were often small relative
to the total value of the finished product when it was exported to the United States and elsewhere.
A significant amount of the profits made from the sale of a product is estimated to have been
accrued to the MNC that owned the brand. This trend, however, has been shifting over the past
decade, as MNC suppliers in China have further developed their capabilities and as Chinese
government policies have pushed for local content requirements, particularly in strategic sectors
such as ICT. As labor and other input costs have been rising, MNCs, as well as Chinese
companies, have been shifting production farther inland in China and, more recently, offshore to
other lower-cost destinations.
To illustrate, when the United States imports such products as iPhones and iPads, it attributes the
full value of those imports as occurring in China, even though the value added there is quite small
(Figure 2). Apple Inc., the U.S. firm that developed these products, is the largest beneficiary in
terms of the profits generated by the sale of its products, and most of its product design, software
development, product management, marketing, and other high-wage functions and employment
occur in the United States. Some partners have a larger value-added role in the Apple GVC than
others; for example, Taiwan-based Foxconn handles the sourcing, manufacturing, and logistics. In
other words, U.S. trade data may show from where products are being imported, but they often do
not reflect the country or countries that ultimately benefit from that trade. In many instances, U.S.
imports from China are really imports from many countries. Yet, the full value of the final
imported product is attributed to China, which results in what some might consider to be an
inflated trade deficit figure.

Measuring trade in value-added terms can mitigate these problems by enabling domestic content
embedded in exports to be assigned to each country that participated in the production of the final
good. In contrast to traditional trade statistics, measuring trade this way can provide a more
detailed picture of the location where value is added during the various stages of production.22
Trade in Value-Added (TiVA)
International and domestic efforts to collect data on trade in value-added (TiVA) have measured
the way value is added through the various parts of the supply chain and stages of production. In
particular, TiVA identifies the origin of the value added of goods and services in cross-border
trade according to the country and industrial sector where that value was added.23 This data
measurement contrasts with traditional merchandise trade data, which attributes the value of an
import or export to a single country. The Organization for Economic Co-operation and
Development (OECD) and the WTO developed a TiVA database, considered to be the most
comprehensive and widely used trade database that provides insight into domestic and foreign
value-added content of gross exports by exporting industries.24 Despite a significant time lag,
such statistics provide a detailed picture of inter-industry relationships in the supply and uses of
goods and services between sectors of the economy. In other words, TiVA data provide a better

22 A joint study by the OECD and the WTO estimated that the U.S. trade deficit with China in 2009 would have been
reduced by 25% if bilateral trade flows were measured according to the value-added that occurred in each country
before it was exported (OECD and WTO, “Trade in Value-Added [TiVA] Database: China,” January 16, 2013). In
addition, another study estimated that 25% of U.S. imports from Canada and 40% of U.S. final merchandise imports
from Mexico consist of value added from the United States (Robert Koopman, William Powers, Zhi Wang, and Shang-
Jin Wei, “Give Credit Where Credit Is Due: Tracing Value Added in Global Production Chains,” National Bureau of
Economic Research Working Papers 16426, October 2011).
23 TiVA data are generated by industry-by-industry input-output tables created by OECD and the WTO. The dataset
covers 64 economies and 36 unique industrial sectors, including agriculture, mining, manufacturing, construction, and
business services, from 2005 to 2016. The OECD expects to release an update providing data for the period 1995-2018
in fall 2020.
24 Given the level of aggregation among the TiVA input-output tables, much of the extensive inter-industry trade that
occurs among the United States and its trading partners, especially in complex sectors such as motor vehicles or
semiconductors, may not be fully captured.

indication not only of the production and movement of goods and services, but also of where they
are being consumed.
Most economists recognize that traditional trade statistics do not accurately reflect the true
content of trade relationships because they represent the gross value of trade (see textbox).25 The
gross value of trade, however, may be misleading because it can (1) distort bilateral trade
balances, resulting in double counting trade flows; (2) attribute production to the wrong
geographical locations; (3) incorrectly specify the technological content of exports at the national
level; and (4) misrepresent the true relationship between imports and exports.26 Given the
multistage, cross-border nature of GVCs, various inputs can be counted multiple times, thereby
inflating the true value of trade occurring at both the national and global levels.
Difference Between Gross and Value-Added Trade Flows:
A Simplified Example

Suppose that Country A ships $100 worth of raw materials to Country B, and Country B further
processes them into $120 worth of goods. Country B then ships these goods to Country C.
Gross Trade Flows
Although Country B added only $20 of value, traditional trade measures would conclude that
Country B exported goods worth $120 to Country C.
Using gross trade flows, Country C would run a $120 trade deficit with Country B but would not
have had a trade deficit with Country A.

Value-Added Trade Flows
On the other hand, value-added trade would count only the value each country uniquely added in
the production process. Country A would have exported $100 worth of goods to Country C, and
Country B would have exported $20 worth of goods to Country C.
Under value-added trade, Country C would have a $100 trade deficit with Country A and a $20
trade deficit with Country B.

Note that Country C’s global trade deficit (i.e., the sum of the trade deficits with Country A and
B) is the same under both accounting systems.

Measure of Global Trade?” (2019).

The rapid growth of GVCs and intra-industry trade (i.e., importing and exporting goods in the
same industry) has significantly increased the amount of trade in intermediate goods, in some
ways blurring the distinction between domestic and foreign firms and goods. Trade in
intermediate goods and services may involve suppliers that provide semi-processed intermediate
goods (that in some instances are imported) that eventually are incorporated into finished exports.
Such trade may also involve forward links or downstream user industries, with production
activities incorporating exported intermediate goods used in the production of finished goods
somewhere else.
As a result, cross-border production and trade in intermediate goods have increased the number of
jobs that are tied directly and indirectly to international trade in ways that are not captured fully
by traditional trade data. As noted previously, trade in intermediates can also lead to productivity
gains in domestic industries, increased sophistication of production, and higher overall economic
activity.
In addition, GVCs challenge traditional trade concepts of production. Such concepts typically
centered on the national level by emphasizing production segmented into discrete units or tasks.
As a result of this segmentation, the growing complexity and cross-border activities of value
chains have focused attention on the way trade data are collected and reported, raising related
questions about the distribution of the costs and benefits of international trade.27 Moreover, the
array of cross-border transactions that occur through GVCs fundamentally alters the nature of
trade data and challenges the use of bilateral trade balances as an indicator of a nation’s trade
performance.
Accounting for Value-Added in Exports
Statistics col ected or estimated on value-added terms attempt to account for the value in exports that consists of
inputs derived from production abroad, and the value of exports used as inputs in the production of finished
products by other countries. The United Nations uses a number of terms to describe these different types of
value added:
Foreign value added: share of a country’s gross exports that is composed of inputs produced in other
countries.
Domestic value added: share of inputs in a country’s exports that originates within that country and is counted
as part of its gross domestic product (GDP).
Value-chain participation: share of a country’s exports that is part of a multistage trade process that includes
the foreign value added used in a country’s own exports and the value added supplied to other countries’
exports. It indicates the extent to which a country’s exports are integrated into international networks.

Source: United Nations Conference on Trade and Development, World Investment Report (2013).
For example, some U.S. exports contain parts, components, and services that originated outside
the United States, while some U.S. imports may contain parts, components, and services from
many countries (including the United States)—not just from the country from which they are
being imported. Figure 3 shows the components of the total value of U.S. gross exports under the
OECD TiVA database in 2011 and 2016.28 In 2016, the largest share of the total value of U.S.
exports was domestic value added, both direct and indirect, which accounted for 87% of the total

explaining a recent decrease in the U.S. value-added content, or as an indicator for developing policy prescriptions.

intermediate goods and services, accounted for 13% of U.S. exports by value added. (See textbox

Examining Industry GVCs: Select Case Studies
Supply chain complexity tends to vary by industry. For example, on average, an auto
manufacturer has approximately 250 tier-one suppliers but over 18,000 across the entire value
chain, whereas an aerospace manufacturer may have an average of 200 tier-one suppliers and
12,000 suppliers in total.30 Examining specific supply chains illustrates how domestic policies,
trade liberalization measures, and advances in services and technology have shaped GVCs and
the varied impacts across different sectors.
Complex Distributed Value Chain: Nike
A global value chain of one company, or even a single product, can cross several countries. As
discussed above, in addition to the raw materials and intermediate inputs that go into the
production of a final good, a GVC may include R&D, management and administrative functions,
freight transport, distribution warehouses, and brick-and-mortar stores before the good reaches
the final customer.
NIKE, Inc. (Nike) is a classic example of a how a multinational company operates with a global
value chain. Although Nike is the “largest seller of athletic footwear and apparel in the world,”
the company’s core business is in the design, development, marketing, and sale of Nike products,
which are the highest value-added activities along the global value chain.31 Most Nike jobs are in
its global U.S. headquarters, located in Beaverton, OR; the company has regional offices located
around the world that perform other administrative and sales activities.32 The company primarily
contracts with independent manufacturers for its footwear and sports apparel manufacturing, most

29 The domestic value-added share of U.S. exports can be segmented further into three components associated with
producing goods for export: (1) activities directly involved in production (which accounted for more than half of the
value added of U.S. exports); (2) activities indirectly involved in production; and (3) domestic value added exported in
goods and services that were subsequently used to produce imports of intermediate goods and services that, in turn,
were exported as final products (less than 1% of the value added).

of which are located outside the United States. According to Nike, many of the independent
contract manufacturers often operate multiple factories and source raw materials locally where
manufacturing takes place.33 Several contractors also have their own subcontractors.34 Nike uses
third-party air and sea freight companies to transport its products from factories to distribution
centers around the world. The distribution centers then ship Nike products to Nike-owned and
third-party retail stores worldwide. Nike also operates e-commerce platforms in the United States
and 45 other countries.
As of February 2020, 600 factories manufacture Nike products. Together, they employ over 1.1
million people, located in 41 countries. Roughly 40% of the factories are in Vietnam (125) and
China (119) (see Figure 4).35 Factories in Vietnam, China, and Indonesia produced approximately
96% of Nike brand footwear and 63% of Nike brand apparel in FY2020.36

Nike, along with other large apparel brands, has started to promote environmental sustainability,
potentially in response to factors such as changing environmental regulations or pressure from
stakeholders and consumers. According to Nike’s sustainability website, the company’s footwear
and apparel currently uses various recycled materials, including plastic, leather, and polyester. In
addition, the company has pledged to use 100% sustainable cotton by 2020. Creating a more
sustainable supply chain may lead companies to find new suppliers or to work with existing
suppliers that can meet their sustainability goals.

Regional Specialized Value Chains: ICT Goods
The electronics value chain, which includes consumer electronics and ICT products, has become
regionalized over the years, and China has emerged as a major global production center for
microelectronics. Global trade in semiconductors involves cross-border design and manufacturing
processes, and such trade can involve a chip crossing national borders several times in the product
development cycle. For example, Taiwan and South Korea have significant fabrication capacity,
while several East Asian economies have strong roles in assembly, testing, and packaging.
Multiple East Asian economies are major exporters of key intermediate ICT components. In
2018, exports from Asia of integrated circuits/semiconductors, which are used in almost every
electronic product, accounted for roughly 70% of total export value, compared with around 50%
in 2005 (see Figure 5).37 As noted above, intermediate and end products may cross borders
multiple times before final export, which may skew the trade data (see earlier discussion on trade
data and value added). Out of the top 10 exporters for these components, seven are from Asia,
with China (including Hong Kong and Macau) being the largest exporter, followed by South
Korea and Singapore. Some of the biggest integrated circuits/semiconductors firms are located in
a small number of countries, which may contribute to the concentration of manufacturing
activities and exports in certain countries.38

semiconductors increased from 16% to 33%. Although its share in total value exported has
increased, most of China’s value-added share is from printed circuit boards. However, trade data
suggest that some GVC production in China may be shifting to other locations, potentially in
response to rising costs in China and U.S. tariffs imposed on Chinese imports since 2018.39
Analysis shows that China’s share in global exports of consumer electronics decreased between
2018 and 2019. During that time, China’s share of global exports of phones decreased by three
percent and the share of computer and tablets exports decreased by four percent. Some countries
that saw an increase in total export value for finished consumer electronics include Vietnam,
United States, and Mexico.40 In addition, although India’s share of global export value for
consumer electronics is still relatively small, its total value exported increased from $2.7 billion
in 2018 to $4.9 billion in 2019.
Multinational companies use contract manufacturers and suppliers that often have their own
production networks, which contributes to the regionalization of the value chain. 41 As mentioned
above, Apple, a U.S.-based company, contracts with Taiwan-based Foxconn, which handles the
sourcing, manufacturing (mainly in China), and logistics.42 One of Apple’s major supplier of
memory chips and display panels for its iPhones is South Korea-headquartered Samsung, which
is also a major competitor in the smartphone market.43 Both Foxconn’s specialization in
electronics manufacturing, and Samsung’s investment in R&D of electronic components, make
the Asia region’s strong production networks attractive to multinational companies.
China’s Role in Global Value Chains44
China is a top global trader and central production point in global supply chains in a range of sectors, from raw
material processing and chemicals to industrial intermediates and consumer goods, including microelectronics.
China’s emergence as this central node is due to a confluence of factors that have played out over time: global
offshoring of lower-end manufacturing to markets with cheaper labor and production costs; Chinese trade,
investment, and tax incentives; and general global trade liberalization, including China’s accession to the WTO in
2001 and the lowering of global technology tariffs through additional WTO agreements. China’s creation of
industrial and trade zones to support domestic manufacturing’s role in GVCs and foreign companies’ efforts to
push into China’s domestic market have been mutually reinforcing as multinationals have played a leading role in
building Chinese supplier capabilities and distribution and logistics networks. Chinese market access barriers—
including policies that require localization of foreign production in order to sell in China and that make direct
imports difficult or more expensive—have also driven the location of manufacturing in China. They are also now
driving the relocation of higher value-added activities, particularly in technology, advanced manufacturing, and
research and development.45 While many firms initially sought out manufacturing opportunities in China because
of perceived lower costs, investments in China can be more expensive, time- and management-intensive, and
challenging than companies initially anticipate. There are also potential hidden risks and costs such as labor issues,
business disputes, and IP theft.46

Since joining the WTO in 2001, China has sought to advance its position in the global value chain. Initially serving
as a final point of assembly for semi-finished goods that were then mostly re-exported, China now has an
economy in which many intermediate inputs are increasingly sourced from China and finished goods (and services)
are directed to both export and domestic consumption. Responding to this evolving business environment,
multinational firms in China have repositioned to focus increasingly on the domestic market for sourcing and
sales.47 The Chinese government has enacted tax, trade, investment, and industrial policies designed to position
Chinese firms to be globally competitive and to encourage or require the transfer of foreign technology and
capabilities to accelerate this advancement.48 China’s policies feature a heavy government role in directing and
funding Chinese firms to obtain foreign expertise and intellectual property in areas where the United States has
strong comparative advantages (e.g., aerospace, semiconductors, microelectronics, and pharmaceuticals).49
Managing Tiered Supply Chains: Boeing 787 Dreamliner
As of October 2020, Boeing employed around 145,000 employees in over 65 countries, including
the United States, and contracts with over 20,000 suppliers and partners globally.50 Regional
offices around the world allow the company to be closer to local markets, as well as build
stronger relationships with its suppliers, which are important in ensuring the company meets
production goals. An often-studied case is Boeing’s production plan for the 787 Dreamliner. The
787 Dreamliner was the company’s first commercial plane built with a tiered supply chain, using
external supply chains for the more labor-intensive production activities in an attempt to reduce
manufacturing time and costs (see Figure 6).51 Boeing contracted with about 50 tier-one suppliers
that were responsible for assembling sub-assemblies manufactured by tier-two suppliers. Final
assembly would be completed by Boeing in its plant in Everett, Washington. In 2004, Boeing
launched production for the 787 with a target delivery date for the first of 50 planes to All Nippon
Airlines in May 2008. Three years after the original date, the first 787 was delivered in September
2011.

The new tiered supply chain model took years for Boeing to optimize by working with its
suppliers to address risks and develop the necessary technology to meet production goals.
Analysts point to several reasons for the delay, including Boeing’s lack of experience in global
supply chain management and technological challenges from scaling up composite materials
previously used for small-scale manufacture of aircraft parts.52 In response to those issues, Boeing
worked with its suppliers to develop new equipment and manufacturing processes to build parts,
as well as to readjust aspects of its supply chain, including increasing production and assembly
processes in its Everett plant. Despite the three-year delay and scaling back the scope of
outsourcing, Boeing continues to use the tiered supply chain model with final assembly of new
787 planes taking place in Everett or North Charleston, South Carolina.53 In October 2020,
Boeing announced plans to consolidate final assembly of 787s at the South Carolina campus,
beginning in mid-2021.54
Regional GVC Integration: North American Motor Vehicle Supply
Chain
The integration of the North American motor vehicle industry began with the Canada-U.S. Auto
Pact of 1965, which eliminated tariff barriers between the United States and Canada on motor
vehicle and parts trade for specific manufacturers.55 The Auto Pact was later integrated into
Canada-U.S. Free Trade Agreement (CUFTA) that went into force in January 1989. The North
American Free Trade Agreement (NAFTA) among the United States, Canada, and Mexico, which
entered into force in January 1994, incorporated CUFTA provisions, eliminating all tariffs and

most nontariff barriers among all three countries, provided uniform rules of origin provisions, and
added new rules and disciplines such as strengthening intellectual property rights protection.56
NAFTA was highly instrumental in the integration of the North American motor vehicle industry.
As manufacturers in each country participated in production sharing, notably along the U.S.-
Mexico border, bilateral merchandise trade significantly increased, creating vertical supply
relationships. During the production process of a motor vehicle, parts from multiple suppliers in
the region are shipped back and forth across borders numerous times before final assembly.57
NAFTA was recently replaced by the United States-Mexico-Canada Agreement (USMCA), which
went into effect in July 2020.
U.S. and non-U.S. automakers own assembly or parts plants in the United States, Canada, and
Mexico.58 Since 1994, the United States has produced a majority of motor vehicles in North
America (64.8% in 2019), although Mexico’s share has increased (from 7.1% in 1994 to 23.8% in
2019) (Figure 7). Between 1997 and 2019, bilateral trade in motor vehicles and parts between the
United States and Canada was relatively constant, while U.S.-Mexico bilateral trade increased in
nominal terms (Figure 8). Bilateral trade data may provide some insight on the level of GVC
integration, but will not capture the value-added as each part or subassembly moves along the
supply chain (see “Trade in Value-Added (TiVA)”).

Current Trends and Outlook
Various trends and policies impact the structure and use of GVCs. Some firms are reviewing the
advantages, disadvantages and risks they incur by using a GVC as well as the foreign and
domestic policies that influence how companies shape of those GVCs. As a result, some
government and private sector leaders are reevaluating their use of and reliance on GVCs.
GVC Risks
Although using GVCs can offer significant benefits, as discussed above, doing so can create
additional costs. Some of the costs are obvious, such as shipping and transporting raw materials
and intermediate goods for final assembly. Other costs may not be so obvious, such as the
resources needed for a firm to manage, coordinate, track, and communicate with its GVC
partners. In forming its GVC, a company typically weighs the risks and costs associated with
each step of its operations, and each potential partner, and configures its GVC accordingly.

When electing to use a GVC, a firm accepts a certain level of risk and loss of control over
different stages of production that its supply chain partners, in turn, accept. For example, a firm’s
consumer reputation often relies, in part, on the quality of suppliers’ intermediate products or
services. Changes in the quality or reliability of a supplier’s product or service could disrupt a
GVC. In addition, GVCs are potentially at greater risk of IP theft and diversion of capabilities
through licensing and subcontracting arrangements. They also often depend on the ability of
contractors to manage labor and other issues, which can pose additional risks. A company may
use contracting terms (e.g., reporting requirements, operational standards, or manufacturing
specifications), technologies (e.g., RFID sensors to track intermediate parts), or strong
relationships (e.g., long-term partnerships) to increase visibility into their supply chain and help
minimize risk.
Certain GVC risks and costs are external and may be beyond a single company’s control.
However, firms must account for them when planning and operating a GVC. Such risks and costs
may require temporary changes, such as those due to local supply shocks, whereas others may
indicate long-term shifts in market conditions. Potential risks and costs associated with GVCs
include the following examples:
 a cybersecurity attack on a supplier may impair a partner’s operations or a firm’s
ability to track or manage overseas operations;
 a natural disaster, such as a flood or tornado, or health crisis, may render a
foreign partner unable to fulfill its contract for a period of time, disrupting other
parts of the value chain that are not directly affected by the disaster;
 a transportation strike by workers in one country may mean that suppliers in
another cannot receive raw materials in a timely manner;
 regulatory changes where a partner is located, such as new environmental or
labor requirements, or changes in component prices (e.g., raw materials, energy)
could increase overall GVC costs;
 losing visibility into the downstream supply chain if a supplier or other partner
uses unidentified subcontractors could hamper a firm’s ability to plan or fully
secure its supply chain;
 new tariffs or duties may raise costs for the importing firm, making foreign
partners no longer as economical; or
 new free trade agreements (FTAs) or trade preference programs may make other
potential partners more cost effective or strengthen competitors.
Some analysts note that certain GVC risks may increase in the future because of growing
geopolitical tensions that lead to abrupt policy shifts, or the impact of climate change causing
more frequent and severe natural disasters.59 Furthermore, costs may increase when a firm
depends on a single supplier or partner for a given value chain link, which can become a choke
point in case of disruption. Diversifying sources and partners can strengthen a company’s GVC
resilience but may require a firm commit extensive resources to manage and oversee the larger
partner network. Firms may increasingly need to have alternate contingency or back-up plans for
such events, identifying substitute sources or suppliers if the current or first-choice partner is
unable to effectively fulfill a contract for a period of time. (See “Reevaluating GVCs” for more
discussion on diversification and other options.)

Global Value Chains: Overview and Issues for Congress

Select Policies Shaping GVCs
Although technological advances and economic factors have enabled GVCs to spread across the
world, government policy is increasingly shaping GVCs. FTAs, preferential trade programs, and
import programs (e.g., free trade zones) offer reduced-tariff benefits to imports that meet certain
requirements. In particular, U.S. import policy may support GVCs by facilitating trade efficiently,
but it may also require importers to exercise responsibility over their supply chains. In addition,
unilateral trade restrictive measures, data flow limitations and national security concerns may
hinder GVCs. Selected policy issues of interest to Congress are discussed below.
Free Trade Agreements (FTAs) and Trade Preference Programs
FTAs shape GVCs by establishing lower trade barriers and harmonizing cross-border policies,
such as those on investment and rules of origin (ROO) that facilitate cross-border trade in parts
and components. Although WTO agreements have lowered tariffs for many goods over the past
decades, FTAs widen the scope of products that may receive duty-free or reduced duty benefits
between trading partners. Some studies have shown that FTAs that cover more policy areas, such
as investment, intellectual property rights (IPR), and competition policy, have a positive impact
on the quantity of components traded and GVC integration.60 The North American auto industry,
discussed above, is an example of GVC integration largely as a result of NAFTA, which was
recently replaced USMCA.61 In addition to removing tariffs on goods produced and traded
between North American countries, NAFTA included provisions for uniform ROO requirements,
lower investment barriers, and stronger IPR protection.
ROO provisions in FTAs may particularly influence how firms decide to organize their supply
chains. Each FTA has its own set of ROO requirements, which are laws, regulations, and
procedures used to determine the country of origin of imported products.62 Such requirements
apply to FTAs to ensure that only eligible trading partners receive the tariff benefits and to
prevent third-party countries from taking advantage of the duty benefits within a free trade area.63
Depending on the FTA and product, conferring origin may require the imported product to meet a
regional value content (RVC) threshold, which requires a minimum percentage of the value-added
of parts, labor costs, and manufacturing process to originate in the FTA region. RVC requirements
encourage manufacturers to source parts and labor within the FTA region. USMCA’s auto ROOs
were negotiated with the goal of incentivizing U.S. manufacturers to source more U.S. parts and
increase U.S. production, but analysis on the possible impact on North American auto supply
chains has shown mixed outcomes.64
When compliance costs outweigh the benefits, U.S. importers and manufacturers may choose to
import under general normal trade relations tariffs under WTO rules. For example, the
Congressional Budget Office estimated higher tariff revenue and lower duty-free imports from

63 This may happen when the third-party country exports to the FTA partner country with the lowest external tariffs and
then moves the goods duty-free to another partner country where it is ultimately sold to consumers.

Canada and Mexico under USMCA as a result of the strict auto ROO provisions. Under the
provisions, automakers can choose pay a relatively low tariff (e.g., 2.5% for passenger vehicles)
rather than incur the various compliance costs, such as relocating manufacturing facilities and
buying more expensive parts.65 To be effective, U.S. trade policy and trade negotiating objectives
would need to find a careful balance between the costs and benefits of ROOs.
Preferential ROOs also apply to certain programs that provide nonreciprocal, duty-free treatment
for certain U.S. imports from eligible developing countries. U.S. trade preference programs like
the Generalized System of Preferences (GSP), African Growth and Opportunity Act (AGOA), and
certain Caribbean-focused programs aim to promote sustainable economic growth through
trade.66 Specifically, ROO for eligible textile and apparel products under AGOA and the
Caribbean programs has specific sourcing and assembly requirements that influence how textiles
and apparel supply chains are formed in the region. Each trade preference program is drafted and
approved by Congress and subject to regular reauthorizations.
Environmentalists have raised concerns that FTAs, particularly those between developed and
developing countries, may negatively affect the environment.67 Manufacturers may move their
supply chains to a developing country FTA partner to take advantage of lower trade barriers and
supposedly lax environmental regulations. In recent years, FTAs have increasingly included
environmental provisions. One study suggested that environmental policies have limited effects
on GVCs and overall trade patterns but may have significant effects on specialization.68 For
example, a country’s stringent environmental policies may lead to development of sustainable
industries and goods. FTAs that enforce uniform environmental policies across a free trade area
may facilitate knowledge sharing or the transfer of clean technologies, leading to more
sustainable GVCs.
Some trade policy observers have noted that trade facilitation at the multilateral and national level
is important to support GVCs.69 Trade facilitation includes policies and regulations that simplify
customs procedures and increase transparency so that goods can flow across borders more
efficiently and lower the cost of trade. The United States is in compliance with most of the WTO
Trade Facilitation Agreement (TFA), which went into force on February 22, 2017, and is involved
in capacity-building efforts in other countries to help them meet their obligations.70

Global Value Chains: Overview and Issues for Congress

U.S. Import Policies
Certain U.S. import policies and initiatives exist to support trade facilitation and global supply
chain security of U.S. imports.
The U.S. Customs and Border Protection (CBP) agency is responsible for trade facilitation,
among other duties. CBP employs a “shared responsibility” approach in which it informs
importers and exporters of their rights and responsibilities under customs laws and regulations.
U.S. importers are expected to exercise reasonable care over imports, including the products’
supply chains, to comply with U.S. customs laws and regulations. For example, Section 307 of
the Tariff Act of 1930 prohibits imports that were mined, produced, or manufactured by forced
labor.71 To ensure that imports comply with Section 307, U.S. importers exercising reasonable
care regarding compliance are responsible for auditing the supply chain to check for products that
may be produced by forced labor.72
CBP also oversees the Customs Trade Partnership Against Terrorism (CTPAT) program, which
was established under the Security and Accountability for Every Port Act of 2006 (SAFE Port
Act) to “strengthen and improve the overall security of the international supply chain and United
States border security.”73 CTPAT allows eligible private sector entities to voluntarily partner with
CBP as long as they meet the minimum requirements, including an assessments of their supply
chain based on established security criteria.74 Eligible entities include importers, customs brokers,
forwarders, contract logistics providers, and others in the international supply chain system.
Participants are identified as low risk and receive a variety of benefits, including reduction in the
score assigned under CBP’s Automated Targeting System, reduced examinations of cargo,
priority searches of cargo, expedited release of cargo, and inclusion in joint incident management
exercises.75
Free Trade Zones
Free trade zones are designated areas, typically located at or near sea, air, or land ports that house
production facilities and related infrastructure. There are roughly 5,300 zones located in 140
countries, including the United States.76 Free trade zone programs differ among countries;
however, zones are generally treated as being outside the customs territory despite being
physically located inside the geographic boundaries of countries. Thus, as part of its GVC, a
company may ship components into one zone and then shift production from zone to zone around
the world for different stages of the process. As a result, the company benefits from duty savings
and, often, streamlined customs procedures as long as the goods stay within the zone system.
Duties are paid and full customs procedures are applied when the products leave the zones and
enter a customs area for consumption.
In 1934, Congress passed the Foreign-Trade Zones Act to establish the United States’ free trade
zone program, called the Foreign-Trade Zones (FTZ) program.77 Today, 195 active FTZs operate

in all 50 states and Puerto Rico. The program is administered by the FTZ Board, which is chaired
by the Secretary of Commerce with the Secretary of the Treasury serving as the Board’s
executive officer. Zones are primarily used for production activities (63%), although they may
also be used for warehousing and other logistical activities (37%), both of which require approval
from the FTZ Board and CBP. Both domestic and foreign status inputs may enter an FTZ, where
they are combined during the manufacturing process to make other products. Around 37% ($297
billion) of goods entering zones are foreign status goods, whereas domestic status goods make up
63% ($407 billion).78 A wide variety of industries participate in the U.S. FTZ program for
production purposes, including U.S. automakers, oil refineries, textile and apparel companies, and
pharmaceutical firms. Some companies have production operations in multiple FTZs across the
United States; for example, General Motors is authorized by the FTZ Board to manufacture has at
16 FTZs across 11 states.79 Goods that are produced in FTZs and eventually enter the U.S.
customs territory for consumption have to pay applicable import duties.
While most U.S. FTAs extend preferential treatment to goods produced in U.S FTZs when they
enter the U.S. market for consumption as long as the ROO requirements are met, NAFTA
contained a provision that did not extend the benefit to FTZ users.80 The provision was not
included in the USMCA implementing legislation, which replaced NAFTA, and was welcomed
by FTZ interest groups that have advocated for the removal of the NAFTA provision.81 U.S. Trade
Representative Lighthizer has been asking Congress to reinstate the provision in a technical
corrections bill.82
Digital Trade and Data Flow Limitations
“Cross-border data flows” refer to the movement or transfer of information between computer
servers across national borders. Cross-border data flows are part of, and integral to, GVCs
because they facilitate the movement of goods, services, people, and finance. For example, e-
commerce relies on cross-border data flows to enable international online payments. Emerging
technologies such as blockchain rely on global data flows to enable firms to track the flow of
intermediate or finished products, customs documentation, certifications, or electronic payments
as they move along the GVC.83 Artificial intelligence (AI) or automated decision-making relies
on collecting and analyzing data that may originate from multiple countries involved in a GVC.
Policies that impede cross-border data flows may decrease efficiency and reduce other GVC
benefits. For example, some policymakers seek to restrict the flow of data beyond a country’s
borders to limit access to online information, protect personal privacy and national security, or
pursue other policy objectives. Policies may act as protectionist measures, such as those requiring

domestic data storage and processing to support local industry or to deter foreign competitors
from entering the market. As a result, data localization policies that restrict cross-border data
flows may limit the growth of individual companies or their ability to participate in GVCs.84
The United States has traditionally supported open data flows, with additional regulations (e.g.,
privacy) at the sectoral level. The lack of multilateral rules governing data flows has led, on the
one hand, to countries creating diverging national data policies and, on the other hand, to efforts
to establish common global rules or norms that may be of interest to Congress (see “Issues for
Congress”
).
National Security-Related Controls
Countries often restrict the export of defense-related items, as well as dual-use goods such as
commodities, software, and technologies with both civilian and military applications.
Multinational corporations seeking to export dual-use items, software, and technology to
incorporate into their supply chains may need to apply for licenses to export those goods to
certain destinations, which can add delay and administrative burden to GVC operations. In the
United States, dual-use export licenses are administered by the Department of Commerce.85 This
issue is especially manifest in terms of exports of sensitive goods, such as semi-conductor
technology or avionics, to China.86
Foreign direct investment (FDI) transactions, such as a multinational firm seeking to build
operations in a certain country, or to merge with or acquire a GVC partner, may also raise
national security concerns. Traditionally, the U.S. approach to international investment has sought
to establish an open and rules-based international economic system consistent across countries.
The rationale for this approach is that FDI has positive net benefits for the U.S. and global
economy, except in cases in which national security concerns outweigh other considerations. The
interagency Committee on Foreign Investment in the United States (CFIUS) advises the President
on the national security aspects of FDI in the U.S. economy. CFIUS’s purview includes a broad
focus on (1) the national security implications of individual foreign investment transactions and
(2) the cumulative effect of foreign investment on certain sectors of the economy or by investors
from individual countries, both of which could inhibit some FDI by GVC partners.87 For example,
in September 2017, President Trump blocked the $1.3 billion proposed acquisition of Lattice
Semiconductor by the Chinese investment company, Canyon Bridge Capital Partners due to
national security concerns.
GVCs and COVID-19
The initial impact of COVID-19 on GVCs became apparent before the official declaration of a
global pandemic. Carefully calibrated just-in-time supply chains began to strain as China initiated

84 According to the OECD, “data localization” refers to a mandatory legal or administrative requirement directly or
indirectly stipulating that certain data be physically stored or processed, exclusively or nonexclusively, within a
specified jurisdiction.

internal lockdowns that affected GVC partners. Several U.S.-based multinational companies,
including Apple Inc. and General Motors, warned of supply chain disruptions and revenue
declines when some of their suppliers or stores in China closed.88 With many complex supply
chains based in the Wuhan region, where the outbreak began, the technology sector was hit
especially hard, leading to lengthy delays in product shipments and higher costs.89
The transport sector on which GVCs depend declined across the globe. Without goods to send
abroad, empty container ships piled up in Chinese ports, transport costs for voyages to China rose
dramatically as available ships dwindled, and U.S. and other foreign ports suffered from
cancelled or “blank” sailings and overcapacity.90 As the pandemic spread across the globe, some
transport lines practiced “slow steaming,” or sailing at reduced speed to help absorb capacity and
save costs.91 For ships that did sail, crews were often left stranded, whether at sea, in port, or at
home because of travel restrictions. As a result, many seafarers worked beyond their contract
terms and often beyond regulatory safety limits, posing a potential humanitarian crisis, according
to international organizations.92
While air cargo does not represent a majority of GVCs, it often carries perishable or time-
sensitive goods such as medical supplies. In 2018, American Airlines moved two billion
pounds of cargo and saw revenues of $1 billion from air cargo.93 As the COVID-19 pandemic
spread geographically, travel restrictions and fear of the virus kept many airline passengers away,
leading to sharp declines in the number of flights and air cargo space, raising prices for what
limited space remained. By May 2020, airlines had grounded roughly three-quarters of their
capacity.94 Some firms looked to express carriers such as UPS and Fedex for extra capacity to
transport goods, and some airlines reconfigured their planes to hold cargo instead of passengers.
Over three-quarters of U.S.-Mexico trade occurs on the highways, and trucking companies
attempted to adapt to the pandemic by switching customers and cargo, focusing on the delivery of
medical supplies or food in high demand.95 In some places, such as Europe, trucks that crossed
national borders were subject to health inspections and other screenings, leading to further
delivery delays.
The overall impact of the pandemic on GVCs has varied by sector. One survey found that total
travel and transport costs for shipping pharmaceuticals to the United States increased on average

224%.96 GVCs of medical products have come under scrutiny during the pandemic (see text
box
). In August 2020, the chairs of both the House Ways and Means and Senate Finance
committees asked the U.S. International Trade Commission (USITC) to conduct an investigation
into pharmaceuticals and other COVID-related industry sectors to understand domestic
production, challenges, and other factors affecting U.S. supply chain resilience, including foreign
trade barriers.97 The report was due December 15, 2020.
Critical Medical Supply Chains98
The COVID-19 pandemic has exposed vulnerabilities associated with the concentration of manufacturing in China
and the United States and global dependence on China for critical inputs and products. China is a major U.S. and
global supplier of medical personal protective equipment (PPE), medical consumables, and active pharmaceutical
ingredients. The spike in PPE and pharmaceutical demands due to the COVID-19 pandemic highlighted the
potential risks of these dependencies on China. According to U.S. trade data, in 2019, China supplied almost 72%
of U.S. imports of textile face masks, 55% of U.S. imports of protective eyewear, and 55% of U.S. imports of
protective garments for surgical and medical use.
The pandemic also highlighted China’s ability to mobilize and nationalize its industry on a global scale, raising new
concerns. For example, in January and February 2020, at the height of the COVID outbreak in China, the Chinese
government organized the large-scale purchase of PPE for China on the global market, adding to depletion of
existing supplies in the United States and other countries such as Australia and Canada.99 The Chinese
government nationalized control of the production and distribution of medical supplies in China, to include PPE.100
China’s nationalization efforts and de facto export restrictions, while understandable as part of its response to
address its COVID-19, may have denied the United States and other countries timely access to critical medical
supplies.
Critical medical supply chains were also impacted when various countries placed temporary export restrictions on
medical goods in response to the COVID-19 pandemic.101 According to the WTO, around 39% of restrictive
trade measures put in place in response to the pandemic has been repealed by mid-October; the number of
measures stil in place on medical goods were not specified.102 WTO stated that the measures reduce total global
supply and limit access of essential goods for importing countries as well as more countries to increase domestic
production, usually at higher prices.103
The global nature of the COVID-19 pandemic highlights the exposure risks inherent in GVCs.
During the pandemic, companies have found their GVCs disrupted when manufacturers in
different regions closed and reopened at different times, interrupting previously smooth flows of
intermediate and final goods. The Global Services Coalition and others appealed to governments
to minimize delays and facilitate supply chains of essential goods and services.104 The United

of pre-arrival documentation.105 The G-20 Ministers reaffirmed their “determination to cooperate
and coordinate,” both on short-term responses to mitigate the impact of COVID-19 and longer-
term efforts to build resilience in global supply chains.106 The G-20 statement endorses measures
that, among others, facilitate trade, promote connectivity, and do not create unnecessary trade
barriers or disrupt GVCs.
Reevaluating GVCs
In response to the Trump Administration’s recent unilateral tariff actions,107 and in light of the
COVID-19-related risks described above, many companies are reevaluating their GVCs and
seeking ways to build greater resilience and increase their capacity to deal with potential
disruptions. In assessing its value chain, a firm may examine risk exposure, lack of sufficient
diversification, scenario analyses should a disruption occur, and potential contingency or back-up
plans. In weighing the added costs and benefits of each link along its chain, a firm would
determine at what point the costs of an additional partner outweigh the benefits that the individual
partner brings. When does a firm reach the point of diminishing returns by further extending
and/or diversifying its value chain? Are the higher costs of one potential partner offset if that
vendor’s location offers greater certainty or access?
As firms analyze their use of GVCs, stakeholders may consider various options to reconfigure or
reinforce their value chain (see Figure 9). Some of these options, while not mutually exclusive,
may include the following:
Exiting certain markets. With the increased tariffs on Chinese imports to the
United States, and increased restrictions on doing business with China, some
firms are choosing to leave China and move to other locations for certain lower
value-added manufacturing, without otherwise changing their GVC
configuration—for example, by substituting a China-based manufacturer for one
in Vietnam.108 An EU Chamber of Commerce survey found that 11% of
respondents were considering shifting their investments out of China; of those,
45% were considering moving to other markets in Asia.109 An earlier American
Chamber of Commerce survey found that 9% of respondents had started to leave
China, with another 8% considering such a move.110 Seeking to capitalize on
these changes, Mexico’s “relocation strategy” aims to attract firms who seek to
shift production out of China.111

Global Value Chains: Overview and Issues for Congress

Similarly, a company that currently relies on a vast network of partners across multiple
countries or regions may want to reduce the number of partners or countries involved in
its supply chain. For example, a firm may want to identify and strengthen its relationship
with key strategic suppliers while reducing the number of tier-two, -three, or -four
suppliers.
Diversification and redundancy. Firms that currently have key suppliers in one
geographic location may seek to diversify and use suppliers in multiple countries
or regions. Diversifying a firm’s value chain partners does not necessarily require
a firm to exit any particular market. For some firms with key Chinese suppliers,
this has been referred to as the “China + 1” strategy. Diversifying and using
multiple suppliers may increase costs (e.g., more management teams or different
transport modes and vendors), lead to a decline in efficiency, and increase
“waste” due to redundancy and excess capacity. On the other hand, a firm may be
able to reduce costs by shifting to a country with lower wage or regulatory costs.
In addition, a company may gain resiliency and long-term sustainability through
its ability to respond to changes in supply, demand, and other circumstances. One
survey found that over 67% of senior executives in the Asia-Pacific region are
considering diversifying their supply chains to be less concentrated in China and
to increase their range of suppliers.112 Another recent survey in Japan found that
57% of companies plan to diversify sources and no longer rely on a single
country.113
For example, Swedish truck maker Scania aims to have at least two sources for most of
its 21,000 components, thereby providing the company with flexibility should one vendor
become unavailable. However, with 35 unique components sourced only in France,
disruptions there during the COVID-19 pandemic shutdown resulted in Scania closing its
operations globally for an extended period.114
Regional supply chains. By selecting partners within a certain geographic
region, a company may minimize the impact of global shocks, reduce
transportation costs and lead times with shortened supply chains, and take
advantage of trade preferences in regional trade agreements (e.g., USMCA or the
Comprehensive and Progressive Agreement for Trans-Pacific Partnership). A
regional value chain could be a hub-and-spoke or a vertically integrated system.
The owner of such a chain may increasingly decide to have more than one region
(e.g., in Southeast Asia and Latin America) to serve different parts of the world
and allow for redundancy. Although a regional supply chain may offer certain
efficiencies, a firm using such a chain might not be able to take advantage of
lower cost or better-qualified suppliers outside a given region. In addition, the
firm would still be potentially vulnerable to disruptions from regional events.
As noted above, policies such as trade preferences and tailored subsidies or incentives
(e.g., infrastructure investments, tax breaks) can help foster regional supply chains. For

example, Japan’s government has actively encouraged Japanese firms to pursue a
“China+1” strategy and to decrease Chinese dependency.
Swedish firm Ericsson, for example, has shifted part of its 5G GVC to Eastern Europe,
including Estonia and Poland, to support European customers.115 As mentioned above,
the integration of the North American motor vehicle industry expanded under NAFTA
and may consolidate further under the rules of the updated USMCA.
Stockpile. GVCs enable just-in-time inventory and supply systems. Companies
that do not want to move or adjust their current GVC may increase warehousing
to stockpile excess inventory at different points along the supply chain, thereby
providing a cushion in case of unexpected events. Stockpiling can be an effective
strategy for industries where demand for products is stable and for firms with
sufficient resources to store excess materials and products. For other industries,
such as apparel, stockpiling is not a tenable option because fashion and consumer
preferences change relatively quickly, or it may not be economically competitive
due to added costs.
As a result of the COVID-19 pandemic, several governments are considering plans to
stockpile essential medical supplies in preparation for a future epidemic.
Vertical production. A firm may want to bring more activities in-house and limit
outsourcing to external partners. This strategy may involve a firm investing in
new capacities, from manufacturing specialty parts to final assembly and
packing. Such vertical approaches could concentrate all steps in the home
market, or some activities could be done abroad. Either way, value chain links
would be under a single corporate structure. While this arrangement provides
greater control, it can be a costly, onerous, and potentially risky strategy as the
firm may need to invest significant resources to develop the full set of required
capabilities and would lose the advantages of risk diversification and efficiency
through specialization. This process may be best suited for a firm that serves only
customers in a single market such as the United States or North America.
Reshore. Some observers and policymakers voice support for reshoring GVCs to
their home country, including the United States. A few companies have opted to
do so, seeking to lower corporate risk exposure and complexity, and to obtain
greater policy certainty and domestic support (potentially both financial and
popular opinion support). Reshoring, however, may lead to higher costs and
create risks associated with a lack of diversification. Some governments have
implemented or are considering policies to actively promote or incentivize
reshoring, sometimes targeting certain industries deemed critical to national
security.
In April 2020, Japan announced that $2.2 billion of its pandemic-related economic
stimulus would help Japanese firms manufacturing certain high-value-added items shift
supply chains out of China back to Japan or to other Southeast Asian countries.116 The
U.S. International Development Finance Corporation is reportedly in talks with some

U.S. firms about the possibility of reshoring manufacturing in select industries.117 The
agency has added staff to focus on domestic reshoring and is to jointly administer a $100
million supply chain reshoring fund with the Department of Defense.118 In addition, the
Trump Administration issued executive orders that incentivize companies to relocate to
the United States by limiting waivers that would allow government purchases of foreign
goods.119
Remain in place. A firm’s management may elect to maintain production abroad
if they are assembling or manufacturing certain products in a country to serve the
local regional market or meet localization requirements set by the government.
Another reason may be high sunk costs or investments the firm may not be able
to recapture. Because 96% percent of consumers are outside of the United States,
many U.S. firms want to establish local relationships to be closer to their end
consumers, deterring them from relying only on a U.S.-based GVC.120
Localization policies force a firm to choose whether to locate in a certain country to
access the local market or to forgo serving that market. For example, India, China,
Argentina, and Nigeria are among the countries that impose local content requirements
for domestic sale of certain goods and service sectors.121
No change. Firms may choose to accept the risks inherent in their GVC and stay
in the foreign market(s). This option may be more feasible for sectors with
multiple potential sources or vendors around the globe, making it relatively easy
to switch between partners without friction (e.g., apparel production). This path
may a good fit for firms that can stockpile goods as a safeguard in case of
disruptions or that has multiple separate product lines and is willing to halt,
temporarily or permanently, production of some items.
Case Study: Pursuing Multiple Supply Chain Strategies122
South Korea’s Samsung has embraced multiple strategies for producing its smart phones and personal computers
after initially concentrating manufacturing in China. The company has recently announced changes as part of its
“ongoing efforts to enhance efficiency across our global production bases.” Samsung announced it has:

Exited China, closing its smartphone plants and halting production of its computers.

Diversified and created redundancy by opening new plants in Vietnam and India.

Vertically integrated to make all components and assemble smartphones in-house.

Stayed in China to produce lower-end smartphones through contract manufacturing, to conduct R&D, and
to manufacture other products such as LCD screens and memory chips.

Advanced and emerging technologies, as discussed above, can help decentralize and diversify
supply chains by automating and digitizing complex decision-making processes. These
technologies can also help increase productivity for manufacturing and services links in a value
chain.
Automation or reshoring may be more feasible for certain industries than others. According to
one study, 67% of workers in the technology sector are concerned about losing their jobs due to
AI, machine learning, and robotic software.123 In other industries, such as apparel, replacing labor
with automation may not reduce expenses enough to offset other costs related to reshoring. For
example, footwear manufacturer Adidas built “speed factories” in Europe124 and the United
States125 that applied advanced technologies such as 3D printing techniques to shorten production
times, require fewer workers, and be located closer to the end customers. After operating for a
couple of years, the company closed the new factories in favor of concentrating its production in
Asia, where it had previously established the majority of its manufacturing and where costs were
lower.126 In contrast to Adidas’ speed factories, as discussed, Nike depends on a vast network of
contract manufacturers (see “Complex Distributed Value Chain: Nike”).

Issues for Congress
Global value chains provide the structure for a significant portion of global trade and investment.
The changing composition of international trade with GVCs as a central aspect of the trading
system raises a number of complicated and evolving issues for firms, workers, and policymakers.
For a given policy, policymakers face consideration of where the policy will have the greatest
effect—whether on the headquarters, on the overseas operations, or on domestic and foreign
companies’ operations in the United States. Conversely, policies could produce results that may
not achieve intended objectives. Selected policy areas that may affect GVCs and possible
questions for congressional consideration are discussed below.
Congressional Research Service

Global Value Chains: Overview and Issues for Congress

Investment and Business Climate
A core issue for Congress is how to create conditions that make the U.S. economy more attractive
for establishing U.S.-based supply chains, as well as for segments of both U.S. and foreign-
parented supply chains. In general, when more value is added domestically, more domestic jobs
are created, along with more opportunities for positive spillover effects—both direct and
indirect—from greater domestic economic activity.
Public policy has a significant impact on the business and investment climate—that is, the
economic, political, and social conditions in which firms operate. The investment climate
“shape[s] the opportunities and incentives for firms to invest productively, create jobs, and
expand,” and it is affected by the interplay of key policy areas.127 These areas include public
governance, human capital and innovative capacity development, the financial system, physical
and digital infrastructure development, tax policy, corporate governance, investment policy,
competition policy, and trade policy. In addition, public policy can affect the cost of production
and profitability of firms. Its impact can be direct and indirect (e.g., through taxes, tariffs, labor
and environmental regulations, accounting and reporting rules, and health and safety
requirements). Other policies affecting the general investment climate, such as energy costs and
subsidies for research and development, also affect firms’ costs and profits.
Public policy may provide incentives or deterrents for GVC parent companies to establish and
retain their headquarters in the United States. This influence applies to both U.S.-based and
foreign companies that may locate regional headquarters in the United States. Policies favorable
to businesses in the United States may also induce U.S. and foreign-owned supply chains to
locate more segments of their production in and related service activity in the United States.
Improvements in U.S. seaports, airports, and other freight-handling infrastructure, and certain tax
provisions, among other things, may increase the incentive to source from abroad or to invest in
business operations in the United States.
In considering GVCs, Congress may examine the following:
 What are the costs and benefits of GVCs for U.S. workers and firms and how do
U.S. investment and economic policies shape and impact GVCs?
 How can these policies encourage U.S. and foreign investment into U.S.
communities that have lost jobs due to offshoring, automation, or other economic
forces?
International Trade
Trade policy (e.g., ROO, import rules, investment policy) may impact the formation and shape of
GVCs in a number of ways. Trade liberalization, through free trade agreements, reciprocal or
unilateral reductions in tariff and nontariff barriers, and regulatory cooperation may increase U.S.
exports, improve the overall profitability of a U.S.-parented GVC, and enable U.S. businesses to
leverage their supply chain operations to access foreign markets.
Looking forward, future free trade agreements, whether involving the United States or other
parties, may influence how firms structure their value chains. Ongoing negotiations at the WTO
could further support the growth of GVCs. For example, in 2019, over 80 countries, including the
United States, initiated WTO e-commerce negotiations, which aim to establish a global
framework and obligations to enable nondiscriminatory digital trade. Digital trade issues such as

127 World Bank, World Development Report, 2005.

Global Value Chains: Overview and Issues for Congress

e-signatures, e-contracts, and related e-commerce measures would build on the commitments in
the WTO Trade Facilitation Agreement to smooth the flow of goods and services across borders.
In considering GVCs, Congress may examine the following:
 Should Congress revise existing trade negotiating objectives to better balance
facilitating GVCs with maintaining U.S. domestic competitiveness and economic
growth?
 Should future FTAs use rules of origin to encourage and support stronger
regional value chains, as seen with the North American motor vehicle industry?
 Does the federal government have sufficient data on trade, and what, if any,
additional resources should be devoted to collecting data and analyzing the role
of GVCs in the U.S. economy? Should federal agencies measure trade in value
added terms? In addition to TiVA, are there other approaches that the United
States should examine and support to enable U.S. policymakers to understand the
interplay of domestic and global developments, measure and manage supply
chain dependencies and risks, assess overall production capabilities of U.S. firms’
GVCs in sectors of concern, and better prepare for—and respond to—future
crises?
Supply Chain Security and Resilience
Supply chain security and transparency can help governments and companies build resilience
against internal and external shocks along global supply chains. Increased transparency may also
help customs agencies, like CBP, facilitate legitimate trade and support national security more
efficiently. Public-private partnership programs, like the CTPAT, may encourage U.S. importers
to be more conscious when managing their GVCs. That said, supply chain transparency remains
limited. Increasing trade volume, especially in a growing e-commerce market, introduces
enforcement challenges for CBP, which may result in counterfeit and other illicit goods entering
the U.S. market. To improve CBP’s efforts in trade facilitation and enforcement, the Department
of Homeland Security (DHS), which oversees CBP, has advocated leveraging new technology to
increase supply chain transparency.128 Congress may consider supporting and funding the
adoption of new technology to improve CBP’s responsibilities.
As discussed above, the COVID-19 pandemic has highlighted the need for resilient supply
chains, so GVCs are less sensitive to sudden disruptions. Some policy experts have suggested that
companies implement stress tests to assess the resilience and potential risks of their GVCs,
similar to stress tests conducted in the financial sector.129 To identify supply chain vulnerabilities,
a GVC stress test could examine certain supply chain characteristics: geographic concentration of
suppliers, supplier interconnectivity, depth of lower-tiered suppliers, supplier dependency and
substitutability, and supply chain transparency.130

House Committee on Science, Space, and Technology, Subcommittee on Oversight, and Subcommittee on Research
and Technology hearing titled “Leveraging Blockchain Technology to Improve Supply Chain Management and
Combat Counterfeit Goods,” May 2018.
129 Following the Great Recession, Congress passed the Dodd-Frank Act, which required banks to conduct stress tests
and to report results to the Federal Reserve. The Federal Reserve evaluates the financial institutions’ capital adequacy
and internal assessment process, among other things, and publishes the results annually, as required under the Dodd-
Frank Act.

Global Value Chains: Overview and Issues for Congress

Congress may consider policies that identify strategic supply chains for essential goods, such as
certain medical and ICT goods, and that implement certain stress tests to identify risks to those
supply chains. The Trump Administration has begun identifying certain goods and services in this
area. On August 5, 2020, the Department of State announced the Clean Network program, which
identifies ICT networks as a critical infrastructure for U.S. businesses and aims to secure
companies’ “sensitive information from aggressive intrusions by malign actors.”131 The program
requires all 5G network traffic of U.S. diplomatic facilities to not use any ICT products (e.g.,
transmission, computing, or storage equipment) from companies such as Huawei and ZTE. ICT
services, such as cellular networks and cloud services, are essential services for companies
managing GVCs.
In considering GVCs, Congress may examine the following:
 Should policymakers consider new approaches to trade negotiations or forms of
cooperation with other countries to increase supply chain resilience in certain
sectors?
 How should policymakers identify supply chains that are important to national
security and public health, and what steps should be taken to increase the
transparency and security of those supply chains?
Congress and the Executive Branch may further examine economic policy and measures to
minimize the impact of future global shocks on the U.S. economy, maintain U.S. global
leadership in GVCs, and ensure that GVCs benefit U.S. workers and firms. Members may take
into account not only the immediate static effects of greater global economic integration and
GVCs, but also the long-term, dynamic effects, which could play an important role in evaluating
their contribution to the U.S. economy.
