China-direct sellers need separate EU and UK tax workflows. IOSS can simplify VAT reporting for eligible EU low-value consumer imports, but it does not remove customs duties. Great Britain has a different low-value sales VAT framework. Northern Ireland must be assessed separately. Confirm the actual transaction with a qualified tax adviser before configuring checkout.

EU IOSS is a VAT scheme, not duty-free shipping

The European Commission's One Stop Shop guidance describes IOSS for eligible distance sales of imported goods in consignments of intrinsic value not exceeding €150, excluding excise goods. Registration and intermediary requirements depend on the seller's circumstances.

Eligibility follows the transaction and consignment, not simply the price of one item. Bulk inventory sent to an overseas warehouse or Amazon replenishment is not automatically an IOSS consumer sale. Do not split or undervalue orders to manufacture eligibility.

What changed for small parcels in July 2026?

The EU Council's adopted measure introduced an interim €3 customs duty per different tariff-subheading category in covered small parcels from 1 July 2026. It is distinct from VAT and from a proposed handling fee.

The legal text, Regulation (EU) 2026/382, defines the temporary treatment for qualifying IOSS and postal consignments. Other imports need their applicable tariff treatment checked. Do not describe every parcel as subject to one flat €3 charge regardless of its contents or route.

The practical consequence is to price customs and VAT separately and have the declaration provider confirm the applicable treatment. An old checkout message saying “all orders under €150 are duty-free” is no longer a safe description.

Great Britain is a different workflow

HMRC's direct-sales guidance explains the rules for goods outside the UK at sale. For covered direct consumer sales into Great Britain in consignments not exceeding £135, the seller generally accounts for VAT at sale; above that threshold, normal import VAT and customs rules generally apply.

Business customers providing a valid UK VAT number and sales through online marketplaces can involve different treatment. Northern Ireland has separate rules. The £135 and €150 thresholds are not interchangeable, and neither is a warehouse handling exemption.

Keep IOSS identifiers out of public article text, parcel marketing inserts and ordinary customer messages. Transmit required identifiers through the authorized carrier or declaration channel. Do not borrow another seller's number.

Test exceptions before scaling

Test an eligible order, an order above the threshold, a refund, a split shipment and a marketplace-collected transaction. Check that the commerce system and declaration provider agree on the value and responsible party. A tax total displayed at checkout is not proof that the import data was transmitted correctly.

When a customer reports a second VAT demand, collect the order receipt and carrier notice and investigate the actual declaration. Do not promise an automatic refund without establishing who collected the amount and which correction process applies.

FAQ

Does IOSS make an EU parcel exempt from customs duty?

No. IOSS concerns VAT. Check the customs treatment separately, including the July 2026 changes.

Can I use an IOSS number for a bulk FBA shipment?

Do not assume so. IOSS applies to qualifying distance sales to consumers, not ordinary bulk stock transfers.

Does every UK order follow the same £135 process?

No. Destination territory, buyer type, marketplace involvement and goods location matter.

Who should confirm the checkout tax setup?

The merchant and its tax adviser, with the marketplace and declaration provider where relevant. The warehouse needs an approved operational instruction.
