Interview
de minimis has ensured that companies like Shein and Temu can offer competitive prices because they're not paying import duty and tariffs like other importers do.

De minimis was not a side benefit for Shein and Temu, it was a core cost advantage that let them mail millions of low priced parcels into the U.S. without the duty bill that traditional importers pay. Once that exemption goes away, the economics shift from tiny direct shipments toward bulk imports, U.S. warehousing, and higher prices, while duty drawback only helps on goods that are re exported or returned unsold.

  • Shein’s playbook depended on two things working together, very cheap China based production and duty free entry on sub $800 parcels. Related research shows the next step is already clear, move best selling SKUs into U.S. warehouses in bulk, then fulfill domestically to protect delivery speed and reduce customs friction.
  • For most domestic ecommerce sales, tariffs are simply a new cost line. Duty drawback is not a general refund on imports. It applies when goods are re exported, used in exported manufactured goods, or sent back abroad unsold, which makes returns and inventory rebalancing the most relevant use cases for retailers.
  • The knock on effects spread beyond Shein and Temu. Supply chain platforms like Trendsi expect low ticket overseas dropshipping to shrink, while fulfillment networks like ShipBob are positioned for a world where more merchants hold inventory in the U.S. and sell across marketplaces from domestic stock.

The market is heading toward a more warehouse heavy and compliance heavy version of cross border commerce. The winners will be operators that can shift from parcel by parcel China shipping to bulk import, domestic fulfillment, and systematic recovery of duties on returns, re exports, and other eligible flows.
