Royal Mail USA 2025 Changes: What UK Sellers Need to Know
If you ship to the USA with Royal Mail, big changes are coming from 29 August 2025 — and UK sellers need to act fast.
The US is removing its $800 duty-free allowance, meaning nearly all parcels sent from the UK to the USA will now be subject to customs duties and taxes.
To manage this, Royal Mail is retiring older service codes and introducing new Delivered Duties Paid (PDDP) services for US shipments.
What’s changing for Royal Mail USA services
Royal Mail’s new PDDP options ensure duties and taxes are paid upfront, avoiding surprise charges for your US customers.
These new service codes include: MTV, MPR, DE6, and BYD.
At the same time, dozens of older service codes — including BPI, ETB, MP4, MTK, DEJ and others — are being retired for US shipments. If you continue using them, parcels may be delayed or refused by US customs.
Why this matters for UK ecommerce businesses
If you sell to the USA, you can’t rely on the old “under $800 = no duty” rule anymore. Every US order now needs:
- Complete customs data (value, origin, HS code, etc.)
- To be shipped on the correct PDDP service code
Failure to get this right can lead to rejected parcels, unexpected charges, and unhappy customers.
