Title 19 › CHAPTER 4 — TARIFF ACT OF 1930 › SUBTITLE III — ADMINISTRATIVE PROVISIONS › Part III — Ascertainment, Collection, and Recovery of Duties › § 1517
Creates a process for Customs to investigate when someone might be avoiding duty rules on imported goods. Key words: Administering authority — the agency named elsewhere that handles antidumping and countervailing duty orders. Commissioner — the head of U.S. Customs and Border Protection. Covered merchandise — goods under an antidumping or countervailing duty order. Enter/entry — bringing goods into U.S. customs territory or taking them from a warehouse for sale. Evasion — using material false statements, wrong or missing information, or acts that reduce or avoid required duties; simple clerical mistakes are not evasion unless they are part of a pattern of careless behavior. Interested party — groups that can complain, including foreign makers, U.S. importers, U.S. producers or wholesalers of similar products, unions, trade groups, and certain agricultural coalitions. Domestic like product — a product like, or most similar to, the covered merchandise. When an interested party or a federal agency gives Customs information that reasonably suggests evasion, the Commissioner must open an investigation within 15 business days. If Customs is unsure whether the goods are covered, it asks the administering authority to decide and pauses deadlines while waiting. Customs can combine related complaints. If health or safety risks appear, Customs will share information with other federal agencies. Customs must give technical help to small businesses that lack resources, but can refuse help if the complaint would not lead to an investigation. The Commissioner must decide within 300 calendar days whether evasion occurred, with a one-time possible extension of up to 60 days for very complicated cases. Customs can ask for more information, send questionnaires, and do on-site checks. If a party won’t cooperate, Customs may draw adverse conclusions and use other available information. Within 5 business days after a decision, Customs must notify the parties who filed the complaint and may inform importers to help them follow the rules. If Customs finds evasion, it will suspend liquidation of affected entries, extend liquidation periods as needed, get duty rates from the administering authority, require cash deposits or bonds, assess duties, and take enforcement actions (including penalties, targeting changes in its computer systems, requiring estimated duties, or referrals for further investigation). Within 90 calendar days of starting an investigation, Customs must decide if there is reasonable suspicion and, if so, take interim steps like suspending liquidation, extending liquidation periods, and requiring security. A person affected can ask Customs for a new administrative review within 30 business days of the decision; Customs must finish that review within 60 business days. After that review, the person can seek court review in the U.S. Court of International Trade within 30 business days. These actions do not stop other civil or criminal proceedings under other laws.
