Circumvention Inquiry into Solar Imports 
Updated May 3, 2023 
On April 1, 2022, the Commerce Department initiated an inquiry into whether Chinese-manufactured 
crystalline silicon photovoltaic (CSPV) cells and panels are circumventing U.S. antidumping and 
countervailing duty orders. Commerce initiated the inquiry in response to U.S.-based Auxin Solar’s 
petition alleging that solar cells and panels imported from Cambodia, Malaysia, Thailand, and Vietnam 
use Chinese-made parts and components to avoid high U.S. tariffs on solar equipment imported directly 
from China. The investigation has been controversial, including among Members of Congress. Some 
stakeholders assert that uncertainty about the tariffs could slow deployment of solar energy in the United 
States while others insist that action is needed to protect U.S. solar manufacturing.  
Background  
In 2012, the Commerce Department and the U.S. International Trade Commission (ITC) determined that 
imports of solar cells and panels from China were being sold below cost (“dumped”) or unfairly 
subsidized and were injuring or threatened to injure the U.S. solar manufacturing industry. Commerce 
imposed two remedial orders. The antidumping (AD) order imposed duties ranging from 18% to 25% on 
goods produced by specific Chinese firms and 250% on imports from all other Chinese firms. The 
countervailing duty (CVD) order, which counteracts subsidies, imposed duties of 14%-15% on all solar 
products from China. In its petition, Auxin contended that certain producers in Southeast Asia have 
manufacturing operations that involve minimal capital investments and technical research and rely on 
Chinese inputs (e.g., solar glass, aluminum frames, and silver paste) to make CSPV cells and panels that 
are then exported to the United States.  
How Commerce Conducts Circumvention Inquiries 
Circumvention inquiries determine whether a good imported from a country not subject to an AD or CVD 
order should be included in the scope of an existing order.  
Any interested party (e.g., relevant domestic and foreign manufacturers, importers, unions, and trade 
associations) may submit a request for a circumvention inquiry. The Secretary of Commerce may also 
self-initiate an inquiry. Once the Secretary receives a request, federal law and regulations establish 
deadlines for further action:

•  Within 30 days of receiving a request containing the required information, the Secretary 
is to initiate an inquiry, publish a notice in the Federal Register, and instruct Customs to 
suspend liquidation (i.e., the final calculation of duties) and require any firm under 
investigation to deposit duties. 
•  Within 150 days of the notice, the Secretary is to issue a preliminary determination.  
•  Within 300 days of the notice, law and regulations require that the Secretary issue a final 
determination. 
•  If the investigation is “extraordinarily complicated,” the Secretary may extend the final 
determination deadline by up to 65 days.  
As part of its inquiry, Commerce considers whether “the process of assembly or completion in the foreign 
country ... is minor or insignificant.” In making that determination, Commerce takes into account the level 
of investment, research, and development undertaken in the foreign country, the nature of the production 
process, the extent of the production facilities, and the value added to the final product. 
If Commerce determines that the goods in question should be included within the scope of the existing 
order(s) (an “affirmative determination”), duties could be applied to goods that entered the United States 
after publication of the notice. In certain circumstances, the Secretary may collect duties on goods entered 
prior to publication, back to the date of the original order(s). Commerce could apply duties to covered 
goods specific to particular producers, exporters, or importers, and on a country-wide basis (i.e., against 
solar imports from Cambodia, Malaysia, Thailand, and/or Vietnam).  
Domestic Solar Industry 
Manufacturing of CSPV panels, the most common source of solar energy in the United States, involves 
four primary stages: the refinement of polysilicon, production of thin sheets of silicon (wafers), 
fabrication of solar cells, and panel assembly. Completed solar systems also require numerous 
components not used to generate electricity, such as inverters that convert direct current into alternating 
current and racking systems that position the panels.  
No CSPV cells are produced in the United States. As of February 2022, 13 U.S. factories assembled 
CSPV panels using imported cells, according to the National Renewable Energy Laboratory. Seven other 
CSPV panel plants closed between 2018 and 2021. In 2020, domestic production accounted for 10% of 
apparent U.S. consumption of CSPV panels. Most new solar installations in the United States use panels 
assembled in Malaysia, Thailand, or Vietnam. Critics of the current circumvention inquiry assert that 
higher tariffs on these imports could raise the cost of solar systems in the United States and reduce 
installation work, the main source of solar-related U.S. employment.  
Issues for Congress 
Critics of the inquiry have raised questions about Commerce’s procedures for initiating circumvention 
inquiries and the role of the Secretary of Commerce. In May 2022, some Members of Congress expressed 
concerns about the relative ease with which an investigation can be initiated, the absence of a domestic 
industry support requirement (which exists for regular AD/CVD investigations), and the absence of a 
procedure for Commerce to consider external factors (e.g., public interest). Prior to the ongoing 
investigation, the House passed H.R. 4521, which would codify Commerce’s circumvention regulations, 
potentially making it easier for Commerce to initiate such investigations. The provisions were not 
included in a later version of the bill that was passed and signed into law (P.L. 117-167). 
On June 6, 2022, President Biden declared an emergency citing Section 318 of the Tariff Act of 1930 and 
authorized the Secretary of Commerce to suspend AD/CV duties on imports of solar cells and modules

from Cambodia, Malaysia, Thailand, and Vietnam for 24 months to support U.S. solar deployment efforts. 
In declaring the emergency, President Biden did not cite to the National Emergencies Act (NEA) and at 
least some observers argued that Section 318 should fall under the NEA. In responding to the criticism, 
the Commerce Department asserted that the President had independent emergency authority under 
Section 318 and noted that, in the alternative, Commerce “[did] not agree that Proclamation 10414 fails to 
conform with the requirements of the [NEA].” Should Section 318 fall under the NEA, Congress could 
terminate the emergency declared by the President. 
Following the declaration of emergency, Commerce proceeded with the investigation, and on December 
2, 2022, issued an affirmative preliminary determination. Per Commerce’s instructions, importers must 
certify that their solar cells and panels meet the requirements of “applicable entries” covered by the 
President’s emergency declaration. Regarding nonapplicable entries, Commerce instructed Customs to 
suspend liquidation and collect cash deposits for entries entered on or after April 1, 2022. 
The investigation continues to raise varying views among Members of Congress. Following Commerce’s 
preliminary determination, some Members raised concerns over the impact the affirmative determination 
may have on the U.S. solar industry and employment and urged the Biden Administration to extend the 
tariff suspension on solar products. Some other Members praised Commerce’s enforcement of U.S. trade 
law and suggested rescinding the proclamation.  
In March 2022, Representative Bill Posey introduced H.J.Res 39 disapproving of Commerce’s September 
16 Final Rule under the provisions of the Congressional Review Act. The House passed the resolution 
April 28. The White House indicated President Biden intends to veto the resolution should it reach his 
desk. Congress could override the veto with a two-thirds majority of both houses of Congress. 
Alternatively, Congress could seek to terminate the emergency under the provisions of the NEA.
