UK-based independent sellers on platforms like eBay and Amazon could face severe sales declines in the US due to new import rules proposed by Donald Trump. Experts compare the impact to a “second Brexit.”

The new regulations will require all parcels containing Chinese-made goods entering the US to pay import duties—up to 15% on fashion items—plus an additional 10% tariff. The policy aims to curb competition from Chinese retailers like Shein and Temu but could also affect larger UK fashion brands such as Asos and Boohoo.

Previously, shipments under $800 were exempt from import tax, making cross-border sales easier. However, this loophole led to over 1 billion parcels entering the US tax-free, valued at $54.5 billion in 2023. The new rules, briefly introduced in February before being paused due to customs overload, are expected to be enforced soon.

The changes could raise costs by $30 to $50 per shipment and add customs delays of up to two days. UK businesses, already facing fierce competition, may struggle to remain competitive in the US market. Some retailers are now considering shifting production to countries like India, Bangladesh, or Turkey to avoid tariffs.
