On January 7, 2020, the US Court of Appeals for the Federal Circuit held that US Customs and Border Protection (“Customs”) has the authority to interpret ambiguous antidumping (“AD”) and countervailing duty (“CVD”) orders. The court overturned the finding made by a three-judge Federal Circuit panel which affirmed the US Court of International Trade’s (“CIT”) decision that Customs acted beyond its legal authority in suspending liquidation of goods prior to the initiation of a scope inquiry by the US Department of Commerce (“Commerce”).

The decision by the Federal Circuit clarifies that Customs has authority to determine whether imports are subject to an AD or CVD order, regardless of any ambiguity in the language of an order. Prior to the decision, the presumption was that Customs only applied orders under instruction from Commerce and did not substantively interpret them. Indeed, Customs often (but not consistently) deferred to Commerce by telling parties to submit a scope ruling request asking Commerce to resolve ambiguous orders. Because the Federal Circuit’s decision gives Customs broader authority to use its own discretion, even when there is ambiguity, Customs will likely defer far less to Commerce when ambiguity arises, imposing AD/CVD duties far sooner than if it had deferred to Commerce to issue a scope ruling.


On December 7, 2012, Commerce issued AD and CVD orders (together, the “Orders”) covering crystalline silicon photovoltaic cells imported from the People’s Republic of China.1 Sunpreme Inc. (“Sunpreme”), a manufacturer of solar modules in China, believed that its solar modules did not fall within the scope of the Orders and did not enter them into the United States subject to the Orders. Sunpreme’s entries went unchallenged by Customs until early 2015, when Customs began to question whether the Orders applied to Sunpreme's merchandise. Customs sought advice from its laboratory and found that Sunpreme’s solar modules were subject to the Orders. As a result, Customs began suspending liquidation of (i.e., imposing estimated AD/CVD duties on and suspending customs clearance of) Sunpreme's solar modules on April 20, 2015. On June 2, 2015, Customs sought guidance from Commerce on whether Sunpreme’s products were subject to the Orders. Commerce responded that any such determination would need to be made by Commerce in a scope ruling proceeding, which would need to be requested by the importer or exporter.

On November 16, 2015, Sunpreme submitted a scope ruling request to Commerce, and Commerce subsequently initiated a formal scope inquiry on December 30, 2015. Commerce ultimately found that Sunpreme’s products fell within the scope of the Orders and instructed Customs to continue suspending liquidation of Sunpreme’s solar modules entered prior to the scope ruling and to begin suspending liquidation of any relevant products entered on or after December 30, 2015. Sunpreme subsequently challenged Commerce’s final scope ruling and its instructions to Customs.

When the case finally made its way to the Federal Circuit, the court ultimately affirmed Commerce’s final scope ruling. With respect to Commerce’s instructions to Customs, the court’s main issue was whether Customs acted within its authority by interpreting the Orders and thereby suspending liquidation of Sunpreme’s products on April 20, 2015, eight months prior to Commerce’s scope inquiry initiation.


The Federal Circuit ultimately held that Customs acted within its authority in initially interpreting the Orders to cover Sunpreme’s solar modules and begin suspension of liquidation. In arriving at this conclusion, the court focused on the interpretation of statutes and regulations and the case law relied on by the CIT.

In particular, the court found that under the law, Customs had a clear statutory mandate to “fix the final amount of duty to be paid on such merchandise and determine any increased or additional duties, taxes, and fees due.”2 The court noted that as part of that mandate, “Customs is both empowered and obligated to determine in the first instance whether goods are subject to existing antidumping or countervailing duty orders.”3 The court noted that Customs cannot expand or alter the scope of an order but that its authority and responsibility to determine whether they apply is not negated by an ambiguous order. The court reasoned that any contrary result would limit Customs’ ability to carry out its statutory role and would encourage “gamesmanship by importers” seeking financial windfalls.4 Accordingly, the court found that Customs is required “to make a determination as to whether existing antidumping or countervailing duty orders apply to the subject goods,” and ambiguity of such orders does not relieve Customs from its statutory obligation.5

The court also pointed to the implementing regulations, highlighting that on their face the regulations contemplate a scenario where products are subject to suspension of liquidation at the direction of Customs, after which Commerce initiates a scope inquiry and ultimately finds that the product in question is not included within the scope of the order.

The court also rejected the CIT’s analysis, finding it inconsistent with case law and distinguishable from the case at hand. In particular, the Federal Circuit distinguished AMS Associates., Inc. v United States6 and Xerox Corp. v United States7 from the present case, noting that AMS is factually distinct from Sunpreme because (1) Customs in AMS originally determined that the goods were not within the scope of the ambiguous order, and (2) Customs had not suspended liquidation, but Commerce nonetheless ordered the suspension of liquidation retroactive to even before the initiation of the scope inquiry. Accordingly, the court found that AMS has no bearing on Sunpreme because Customs ordered suspension of liquidation on April 20, 2015, and such suspension continued after Commerce’s final scope ruling. In other words, there was nothing “retroactive” about Commerce’s instruction to Customs.

The court likewise found that Xerox was distinguishable from Sunpreme because it dealt with a completely different legal question. The court acknowledged that Xerox described Customs’ authority to “fix[] the amount of duty to be paid” as “ministerial”8 but rejected the notion that this excluded Customs from interpreting ambiguous scope language.9


The Federal Circuit’s decision in Sunpreme recognizes Customs’ statutory authority to evaluate both the product and an AD or CVD order if Customs suspects that the importer’s product may fall within the scope, regardless of any ambiguity in the language of an order.

Importers could face an increased likelihood that Customs will suspend liquidation of their products in the face of ambiguity, instead of deferring to Commerce for a final scope ruling as the agency often has done in the past. Therefore, importers could be subject to more estimated AD/CVD duties extending to the period prior to Commerce’s initiation of a scope ruling.

Consequently, importers should proactively monitor whether their products could be subject to an ambiguous order. Should questions arise, importers should consider the pros and cons of approaching Commerce and/or Customs to address the ambiguity.
