How to Comply With U.S. Import Regulations

Complying with U.S. import regulations means meeting the requirements of U.S. Customs and Border Protection (CBP) and every other federal agency that controls your specific product — accurately, and with records to prove it. As the importer of record, the legal duty is yours: you classify the goods, declare their value and origin, pay the right duties, and keep the paperwork. A customs broker can file on your behalf, but the responsibility does not transfer. This guide walks the core obligations every U.S. importer shares, then points you to the rules for regulated goods like food, medical devices, and pharmaceuticals.

You Are the Importer of Record — and the “Reasonable Care” Standard Is on You

The importer of record carries personal legal responsibility for every entry. The Customs Modernization Act of 1993 shifted the duty to declare classification, value, and rate of duty onto the importer, who must exercise “reasonable care” under 19 U.S.C. § 1484. In practice, reasonable care means you take real steps to get the entry right: you consult the tariff schedule, seek a binding ruling or professional advice when the answer is unclear, and document how you reached your conclusions.

Relying on a customs broker does not, by itself, satisfy reasonable care. CBP can still hold you liable if the underlying declaration is wrong. The standard is about your process, not who pressed the button.

The Entry Process in Plain Terms

Importing a commercial shipment runs through a predictable sequence — our introduction to U.S. customs regulations covers it for first-time importers. Most filings now move electronically through CBP’s Automated Commercial Environment (ACE), the single window through which CBP and partner agencies receive import data.
