Why Shein Is So Cheap — and What Changed in 2025

Shein launches about 4,700 new styles a day, and a new style typically starts with just 100 to 200 pieces, according to its 2026 IPO filing. Winners can be reordered in as few as five days. But much of that machine's U.S. volume crossed the border in low-value parcels that paid no import duty — until the U.S. de minimis exemption ended in 2025. This video separates what Shein owned (the test-and-reorder system, the supplier network, cross-border fulfillment) from what it rented (a customs rule), and shows what bent when the rented layer disappeared.
