US Customs Scrutinizes Importer Records Years After Shipment

US Customs and Border Protection (CBP) is now examining import entries for months after cargo has been released, according to trade compliance specialists. Importers remain legally responsible for retaining supporting documentation for five years, even after goods clear the border.

During a CargoTrans webinar, Rennie Alston, director of trade compliance at the firm, clarified that an immediate release of goods is only a conditional release by CBP. The agency can review an entry through a 314-day 'liquidation' process. Alston warned that tariff volatility has led companies to change suppliers, routes, declared values, and countries of origin, making this post-release scrutiny critical.

The Shift to Historical Trend Analysis

CBP is moving beyond inspecting individual shipments to analyzing patterns across an importer's entire history. Nunzio De Filippis, co-CEO of CargoTrans, stated that investments in technology and artificial intelligence allow CBP to identify such trends "at much faster speeds than ever before." This means abrupt changes in an importer's declarations can now be flagged rapidly by the agency.

Alston explained that customs operates on a presumption of guilt upon the appearance of noncompliance, contrary to the typical 'innocent until proven guilty' standard. Importers must demonstrate 'reasonable care' to counter this assumption. He warned that customs could interpret sudden changes as attempts to circumvent tariffs unless companies can provide a clear justification.

The Need for Pre-Shipment Visibility

To defend their declarations, importers must have full visibility of a transaction before goods are shipped. Alston said this includes understanding purchase orders, commercial invoices, quantities, origin, and classification. Companies should not rely solely on supplier documentation or their customs broker to establish correct shipment details.

Alston urged importers to strengthen oversight of their customs brokers and to proactively examine their own customs data. He cautioned against using the defense of "this is how we've always done it," as this could prompt CBP to expand its review beyond a single entry and investigate how long a questionable practice has been in place.

The compliance specialists' warnings were reported by The Loadstar. The webinar highlighted that in an era of tariff volatility and enhanced technological scrutiny, US importers need comprehensive internal controls and documentation to manage post-entry compliance risks effectively.
