Section 321 is a U.S. Customs and Border Protection (CBP) regulation that provides duty-free and tax-free entry for low-value shipments, specifically those valued at $800 or less per shipment per day. It’s a critical provision for cross-border eCommerce businesses looking to streamline imports into the U.S.

Key Features of Section 321:

  • Duty-Free Threshold: If a shipment’s value is $800 or less, it can enter the U.S. without paying customs duties or taxes.
  • One Shipment per Day Rule: The exemption applies once per day per recipient. Multiple shipments exceeding this limit may lose eligibility.
  • No Formal Entry Required: Section 321 allows informal entry, avoiding complex paperwork and reducing clearance time and cost.
  • Applies to E-commerce and Direct-to-Consumer Models: Especially useful for DTC brands, dropshipping, and marketplaces sending products directly to U.S. customers.

Benefits for E-commerce Businesses:

  • Lower landed costs (no tariffs or duties)
  • Faster delivery due to simplified customs processing
  • Easier scaling for international brands entering the U.S. market

Limitations:

  • Restricted Items: Some products like alcohol, tobacco, and goods subject to FDA, USDA, or CPSC regulations are not eligible.
  • Commercial Quantity Scrutiny: If CBP suspects that multiple shipments are being split to stay under the threshold, they can deny the exemption.
  • Record-Keeping: Although it’s a low-barrier entry method, companies should maintain shipment records in case of audit.
