Title 19 › Chapter 29— UNITED STATES–MEXICO–CANADA AGREEMENT IMPLEMENTATION › Subchapter II— CUSTOMS PROVISIONS › § 4533
The Secretary of the Treasury may check if a product really counts as an originating good under sections 4531 or 4532, using the USMCA rules in article 5.9. The Secretary may also check textile and apparel items under article 6.6. While checks are happening, the President can order that goods only be released if duties are paid or security is given. For textiles and apparel, the government can also suspend or deny USMCA tariff benefits, detain items, or refuse entry if the Secretary finds missing or wrong information or suspects customs violations. A "negative determination" means the Secretary finds a claim false or that the good does not qualify for USMCA tariff benefits because the importer, exporter, or producer failed to answer questions, refused or blocked site visits or access to records, or otherwise did not follow the rules or tried to get around them. Before making that finding, the Secretary must ask the exporter or producer for information when the claim is based on their certification, and must ask the importer and any supporting exporter or producer when a site visit is used for textiles. After a negative finding, the Secretary can deny the USMCA tariff benefit for that good. If a person repeatedly makes false or unsupported claims for identical goods, Customs and Border Protection may withhold USMCA benefits for that person’s entries until the person shows they follow the rules. The Secretary must interpret these rules to prevent circumvention.
