The New Rules of Cross-Border Commerce: Selling After De Minimis

Key takeaways

• De minimis is gone in the US, EU, and UK. The duty-free model for low-value imports that powered modern e-commerce is over across three of the largest Western markets.
• The liability is moving to you. Under the new EU and UK frameworks, the merchant or marketplace becomes the legal customs debtor - not the customer or the carrier.
• Landed-cost clarity is now a conversion lever. Showing duties upfront is the difference between a completed sale and a cart abandoned at the border.

For years, de minimis thresholds let low-value goods cross borders without duties or full customs processing. A blazer from France, vintage from Japan, boots from the UK - if the parcel sat under the buyer's home threshold, it shipped straight to the door. In 2024 the EU cleared 4.6 billion such parcels, and the US processed 3.7 million de minimis shipments a day.

That model is now closing. Over the past year, the US, EU, and UK each moved to end their de minimis exemptions. This is not a tweak to one country's rules. It is a structural reset of how low-value trade works across the West, and it changes what every cross-border brand owes, declares, and shows at checkout.

What "post-de minimis" actually means for your margins

De minimis was an exemption from customs duty for low-value imports. Remove it, and parcels that once entered duty-free now face duties, processing fees, and stricter documentation. The all-in landed cost per order goes up, and the brands that absorb that quietly will watch margin erode order by order. The ones that stay ahead model the new cost before the deadlines hit.

The United States: tariffs, refunds, and a moving target

The US ended de minimis for China in May 2025 and for all countries that August. Tariffs on 53 million shipments generated roughly $166 billion before the Supreme Court struck down the IEEPA tariffs in February 2026, ordering refunds through the new CAPE portal. A 10% global tariff then took effect under Section 122. De minimis itself remains suspended and is set to expire for good on July 1, 2027. The headline for operators: the policy keeps moving, but the duty-free floor is not coming back.

The European Union: the €3 duty and the data you now owe

From July 1, 2026, every parcel entering the EU owes customs duty regardless of value. Shipments under €150 face a €3 charge per line item, declared via IOSS using the H7 declaration. It is a stopgap until the EU Customs Data Hub goes live around 2028. New requirements for product identifiers, HS codes, and country of origin begin from November 1, 2026 - and the merchant becomes the default legal customs debtor, liable for the duty on top of VAT.

The United Kingdom: what's decided and what's still open

The UK's £135 exemption holds through at least December 31, 2026, with full removal expected by March 2029. What is settled: sellers and marketplaces become the customs debtor, item-level data replaces the old BIRDS dataset, and duty is paid on a quarterly cycle. What is still open: the exact data required, whether non-UK sellers must appoint a fiscal representative, and whether a low-value handling fee applies. The direction is locked even where the detail is not, so the SKU-level cleanup is worth starting now.

DDP vs DDU: why surprise fees kill conversion

When duties are not collected upfront, the customer gets hit at the border. Return rates spike, support tickets multiply, and many abandon the package rather than pay. Delivered Duty Paid fixes this by showing the full landed price at checkout, so there is nothing extra to pay on delivery. Price certainty is not a compliance nicety - it is a conversion lever.

How to prepare before the deadlines hit

Clean your SKU-level data: accurate HS codes, country of origin, declared value, and customs-ready descriptions. Recalculate your true landed cost per order. Move to DDP so customers see the full price before they buy. Swap is the infrastructure behind modern commerce, consolidating duties, taxes, compliance, and returns in one system and keeping you as merchant of record - so you can sell across markets without rebuilding your operation for each one.

The duty-free era is over. The brands that build for the new rules keep selling everywhere.
