Antidumping and countervailing duty orders are written as scope language, a description of covered merchandise, and the fights happen at the edges of that description. There are two distinct doors for edge cases and they lead to different agencies. A scope ruling application asks the Department of Commerce whether a specific product falls inside an existing order's scope, decided from the scope language and the product's characteristics under 19 CFR 351.225. An EAPA investigation, under the Enforce and Protect Act of 2015, asks CBP whether covered merchandise is entering through evasion, transshipment, misclassification, or false origin claims. Importers file scope applications to get certainty about their own product. Competitors and domestic producers file EAPA allegations about somebody else's entries. Sending an evasion complaint to Commerce or a scope question to CBP's evasion process gets a polite redirect and loses months.
A scope ruling is a product question
The scope application lives or dies on the product record: physical characteristics, specifications, end use, marketing, and how the product squares with the scope language and any prior scope determinations. Commerce reads the scope text first and the product second, and the order of that reading matters. A product that feels different commercially can still be inside the scope if the written description reaches it, and a product that looks similar can sit outside if a defining characteristic is absent.
While a scope inquiry runs, entries do not pause. Liquidation and cash deposit instructions follow CBP's messages implementing Commerce determinations, and importers who assume a pending application suspends their exposure can find entries liquidated at the order rate. Get advice on suspension of liquidation and bonding for the affected entries at the time the application is filed, not when the determination lands.

EAPA is an evasion investigation, with teeth at the border
An EAPA allegation needs reasonably available information that evasion is occurring, and CBP works to statutory timelines, deciding whether to open an investigation quickly and whether interim measures are warranted while it proceeds. Interim measures can include suspending liquidation of the entries under investigation and requiring cash deposits or bonds at the order rate, which changes the alleged evader's economics long before any final determination. That is deliberate. Evasion that stays profitable during a two year investigation is evasion that continues.
For importers on the receiving end, the practical point is documentation. An EAPA inquiry into transshipment is answered with the production story: where the goods were actually made, mill or factory records, transport documents that match. An importer buying through a new third country supplier at a price that only works if the order does not apply should assemble that file before CBP asks, because assembling it after interim measures land is assembling it under deposit requirements.
The order rate is not the only number in the room
AD/CVD exposure stacks on top of column 1 duties and any Section 301 or 232 duties on the same line, and cash deposit rates move with administrative reviews, sometimes years after entry. That lag is why scope certainty is worth buying early for a product line with volume. A favorable scope ruling removes the whole stack question for that product. An unfavorable one at least prices the product honestly before the importer builds a market at a margin the duties will take back with interest.
Frequently asked questions
Who decides whether a product is within an AD/CVD order's scope?
The Department of Commerce decides scope questions through the scope ruling process under 19 CFR 351.225, based on the order's scope language and the product's characteristics. CBP then implements the determination at entry through its instructions.
What is an EAPA investigation?
An investigation by CBP under the Enforce and Protect Act into whether merchandise covered by an AD/CVD order entered the United States through evasion, such as transshipment, misclassification, or false origin. CBP can impose interim measures including suspension of liquidation while it investigates.
Does filing a scope ruling application pause duty exposure?
Not by itself. Entries continue under the instructions in effect, and importers should address liquidation and deposit exposure for affected entries when the application is filed rather than assuming the pending question freezes the entries.
What should an importer hold if its supply chain could face an EAPA inquiry?
A production file for the goods: factory records, origin documentation, transport documents, and supplier information showing where the merchandise was actually made. That file is the answer to a transshipment question, and it is far easier to build before an inquiry opens.
