When you fulfill marketplace orders into the European Union, customs duties and EU import VAT are assessed at the border based on the goods, their value, and the shipping terms. In practice, the party that collects and remits VAT and pays duties depends on whether the marketplace is deemed the supplier, whether IOSS is used, and whether you ship Delivered Duty Paid (DDP) or Delivered At Place (DAP).
This matters most for e-commerce sellers shipping from outside the EU to EU consumers because marketplaces and carriers increasingly require clean VAT and customs data to complete EU customs clearance for e-commerce shipments without delays or returns.
The questions below break down duties, VAT roles, and the impact of IOSS, OSS, and EORI on EU order fulfillment.
What are customs duties and import VAT for EU marketplace orders?
EU customs duties and EU import VAT are two separate border charges that can apply when goods enter the EU from a non-EU country. Customs duties are tariff charges based on product classification and origin, while import VAT is a consumption tax applied to the import, often calculated on the goods plus certain import-related costs.
For marketplace orders, the key point is that VAT and duties are triggered by the import event, not by where your business is based. Whether a shipment is stopped, cleared quickly, or returned often comes down to whether the parcel data matches the commercial invoice, the correct commodity code is used, and the VAT collection method is properly declared.
In most consumer e-commerce flows, you will see three common outcomes:
- VAT collected at checkout when the marketplace or seller uses an eligible VAT scheme such as IOSS for certain low value consignments.
- VAT collected on delivery when the shipment is sent without an upfront VAT mechanism and the carrier collects import VAT from the buyer before delivery.
- Duties due at import when the goods are above duty thresholds or fall into categories where duties apply, regardless of how VAT is handled.
Even when duties are not due, EU import VAT can still apply, so it is important not to treat duty free as tax free.
Who is responsible for charging and paying VAT and duties (seller, marketplace, buyer, carrier)?
Responsibility for charging and paying EU import VAT and EU customs duties depends on the sales model and shipping terms. In many marketplace transactions, the marketplace may be responsible for collecting VAT at checkout under EU rules for certain cross border B2C sales, while the carrier handles customs clearance and collects any border charges not prepaid.
To make this practical, separate who collects from who pays:
- Marketplace may collect VAT at checkout in scenarios where it is treated as the supplier for VAT purposes, and it may provide the data needed for clearance.
- Seller is typically responsible for accurate product data, correct invoice values, and choosing shipping terms such as Delivered Duty Paid (DDP) when the seller wants to prepay import charges.
- Buyer often pays import VAT and duties when shipments are sent DAP and charges are collected on delivery.
- Carrier or customs broker submits customs declarations, advances charges in some models, and collects amounts due from the paying party.
Delivered Duty Paid (DDP) usually means the seller arranges and pays duties and import VAT as part of delivery, while DAP usually means the buyer pays on import. The exact allocation can vary by carrier program and marketplace requirements, so align your Incoterms, checkout messaging, and shipping labels so the buyer experience matches what customs will do at the border.
How do IOSS, OSS, and EORI numbers affect EU order fulfillment?
IOSS, OSS, and EORI affect EU customs clearance for e-commerce by determining how VAT is reported and which identifiers must appear in shipping and customs data. IOSS marketplace VAT enables VAT collection at checkout for eligible low value B2C consignments imported into the EU, OSS supports VAT reporting for certain intra EU B2C sales, and EORI identifies the economic operator interacting with EU customs.
What IOSS changes for marketplace VAT and border clearance
IOSS marketplace VAT is designed to simplify VAT for distance sales of imported goods in eligible low value consignments. When IOSS is correctly used, VAT is collected at checkout and the IOSS number is transmitted electronically to customs, which can reduce delivery friction because the carrier does not need to collect import VAT from the buyer at the door.
Key operational points:
- Use IOSS only when the shipment qualifies and the IOSS data is transmitted in the correct field, not just printed on paperwork.
- Keep product descriptions and values consistent across the order, invoice, and electronic customs data.
- Do not assume IOSS removes EU customs duties, because duties depend on the goods and thresholds, not on the VAT scheme.
What OSS and EORI change for ongoing EU fulfillment
OSS generally applies to certain B2C sales within the EU, such as when goods are already in free circulation in an EU Member State and you sell to consumers in other Member States. It is not an import VAT mechanism, but it can simplify multi country VAT reporting once goods are inside the EU.
An EORI number is a customs identifier used in declarations and customs interactions. If you act as the importer of record in a DDP model, you typically need the right customs setup, which often includes an EORI and aligned broker instructions. If the buyer is the importer under DAP, the buyer or their appointed party may need to provide identifiers depending on the shipment and Member State practice.
How EARP helps with EU duties and VAT compliance for marketplace fulfillment?
We help non-EU sellers reduce EU customs clearance for e-commerce friction by aligning marketplace fulfillment workflows with EU import VAT and EU customs duties requirements, while also supporting product compliance readiness under the General Product Safety Regulation (EU) 2023/988 (GPSR) and the Market Surveillance Regulation (EU) 2019/1020 (MSR). This keeps listings, shipping data, and compliance contacts consistent when marketplaces or authorities request information.
- Marketplace readiness checks to confirm your listing and fulfillment setup matches common platform requirements for EU selling, including Responsible Person expectations under GPSR.
- Documentation and process support to help you organize and verify the presence and completeness of required product safety documents and make them available to authorities when requested.
- Clear role mapping so your team understands when the marketplace, seller, buyer, or carrier typically handles VAT collection, duty payment, and customs data submission.
- EU based regulatory representation designed for non-EU manufacturers and e-commerce sellers that need an independent compliance partner focused on continuity and neutrality.
If you want to reduce delays and listing blocks tied to VAT, clearance data, and EU compliance roles, review our EU compliance services and then reach out through our contact page to discuss your marketplace fulfillment setup.
