Drop-shipping (Shopify, Etsy, Amazon) creates customs compliance complexity: who is the importer of record, what entry type applies, how Section 321 changes affect economics. The 2025 Section 321 tightening eliminated informal entry for most categories – full duty plus Section 122 plus Section 301 (where applicable) now applies to most direct-to-consumer parcel imports.

This guide covers Drop-Shipping Customs Compliance. Specialty customs topics range from valuation methodology to specific cargo types and regulatory overlays.

Practical implementation depends on company size, sector, and operational structure.

Importer of record question

Drop-ship configuration: who is the IOR? Often the U.S. consumer or the platform (varies by structure). Misallocation creates compliance exposure.

Section 321 changes (2025)

Tightening eliminated informal entry for most categories. Most parcel imports now require formal entry.

Formal entry economics

For low-value goods previously cleared informally, full duty stack now applies. Effective rates often double or triple.

Mitigation patterns

FTZ for staged inventory, U.S.-side bonded warehousing, classification audits, USMCA-qualifying production shifts.
