US sellers can use the EU Import One Stop Shop, or IOSS, for eligible consumer goods imported in consignments with an intrinsic value no higher than €150. A US-established seller generally needs an EU-established intermediary. IOSS simplifies VAT collection and reporting; it does not make shipments free of customs duties or carrier fees. This article separates the checkout, shipping, and reporting decisions for direct US-to-EU sales.
Key takeaways
Check the consignment’s eligibility before offering IOSS checkout.
Separate your direct-store orders from marketplace-accounted orders.
Keep VAT, customs duty, and carrier fees as distinct components.
Reconcile monthly VAT reporting to shipment and refund records.
Decide whether the order belongs in IOSS
The European Commission describes the import scheme for eligible distance sales of imported goods up to €150; goods subject to excise duties are excluded. The relevant concept is intrinsic consignment value, not a seller’s annual turnover or its average order size. Goods already stocked in the EU belong to a different VAT analysis. The EU online seller guide covers the wider context.
Build an eligibility check that records dispatch country, destination, customer type, product category, currency conversion, and consignment value. Keep exceptions out of the standard IOSS workflow for review. Do not split a higher-value commercial order artificially to force it below a limit. Ask the carrier and intermediary how order consolidation or partial fulfillment changes the declaration process.
Arrange the intermediary and channel responsibilities
The Commission’s registration guidance generally requires non-EU sellers to appoint an EU-established intermediary, subject to a limited mutual-assistance exception. A US seller should plan for an intermediary rather than borrowing another merchant’s number. Confirm the services covered, onboarding evidence, reporting deadlines, fees, and process for corrections before configuring checkout.
Keep direct sales separate from marketplace orders where the platform is treated as the supplier for VAT. Document whose IOSS identification belongs to each eligible shipment and which party reports the sale. Put those decisions in the order export, not just an onboarding email. The shipping team needs an operational rule it can apply without guessing from the storefront name.
Configure VAT and protect the customs handoff
IOSS uses the VAT treatment applicable to the customer’s destination and goods. Do not assume one EU-wide rate. Record the destination, product category, taxable amount, VAT rate, VAT collected, and currency information required by the reporting process. Show the customer a clear explanation of which charges are included in the checkout price.
Transmit the appropriate IOSS identifier securely through the carrier’s approved customs-data process. Avoid publishing it in open website content or treating it as a promotional registration badge. Test that the identifier and VAT-paid information reach the declaration system for the correct order. A successful card payment does not prove a successful customs handoff.
What changed for small-parcel customs duty in July 2026
The Council’s February 2026 final approval states that an interim €3 customs duty applies from 1 July 2026 to each different item category, identified by tariff subheading, in qualifying small parcels under €150. This is separate from VAT and from the additional handling fee addressed in the customs reform. Do not keep advertising a blanket duty-free promise simply because an order uses IOSS.
For illustration, a parcel with two relevant tariff categories can produce €6 under that category-based rule. It is not necessarily €3 per physical unit or one €3 charge per parcel. Confirm the actual scope and declaration treatment with the carrier or customs adviser. The Council’s 3 September 2026 announcement also describes a separate handling fee planned by 1 November 2026, with its amount to be set by the Commission. Verify the final implementation before pricing later shipments; do not treat a future fee as already collected.
Worked example: keep VAT and landed-cost components separate
Assume an eligible hypothetical order has a €100 VAT base and a 20% destination VAT rate. VAT arithmetic gives €20. The rate and base here are assumptions for illustration, not a statement about a particular product or country. Whether duty, transport, or another charge belongs in the actual VAT base must be determined for the real transaction.
Create separate ledger fields for merchandise, transport, VAT, customs duty, carrier administration fees, and refunds. Then compare the customer’s promised total with the carrier’s expected collection process. If a buyer is charged again at delivery, request the customs notice and order receipt before classifying the problem. Duplicate VAT, an unpaid duty, and a carrier service fee require different explanations and remedies.
Close the monthly reporting loop
IOSS reporting is monthly. Agree an internal cutoff with the intermediary that leaves time to reconcile order records, cancellations, dispatch changes, and returns before the statutory submission. A daily settlement report alone is insufficient because it may net fees and refunds or omit the destination VAT details. The Commission’s registration and reporting guidance should govern the process.
Match each reported order to its customer destination, VAT decision, shipment reference, responsible party, and adjustment history. Investigate orders taxed at checkout but not shipped, orders shipped under a different channel identifier, and credits lacking an original invoice link. For broader cross-border decisions, see VAT, GST, duties, and platforms. Maintain separate controls for each tax rather than treating IOSS as an all-purpose import solution.
Frequently asked questions
Does a US sales tax permit replace IOSS registration?
No. A US state permit and the EU import VAT scheme concern different obligations and administrations.
Does IOSS cover consignments over €150?
The import scheme described here is limited to eligible consignments with intrinsic value not exceeding €150. Higher-value goods need a separate import process.
Does using IOSS remove the 2026 small-parcel duty?
No. IOSS addresses VAT. Customs duty must be evaluated separately under the applicable import rules.
