Choosing between US vs EU suppliers is not simply a question of where a company is registered. The location of the inventory that fulfils an order can affect delivery time, customs handling, VAT obligations, returns and customer experience. Use this checklist to compare the full fulfilment setup before committing to a supplier.

Start with the warehouse, not the company address

A supplier may operate in one country while storing inventory in another. For a fair US-versus-EU comparison, record the warehouse that will actually pick, pack and dispatch the product for each destination market.

Public aggregated records as of August 28, 2026 include approximately 190 US-based records and substantial European coverage, including about 420 in Poland, 80 in the United Kingdom, 30 each in the Netherlands and Germany, and smaller groups across several other European countries. These figures indicate sourcing breadth, not a guarantee that every record has local stock or identical fulfilment capability.

  • Ask where the product is physically stocked today.
  • Check whether all variants, sizes and colours ship from the same location.
  • Confirm whether orders can be split across warehouses or countries.
  • Establish what happens when the advertised warehouse is out of stock.
  • Treat an EU warehouse claim as a product- or programme-level detail that must be confirmed; only a small share of the aggregated records publicly indicate EU warehouse capability.

VAT and tax checklist

VAT treatment depends on the seller’s location, the customer’s destination, the transaction structure and the value and movement of the goods. A US supplier shipping to an EU customer may create a different import and tax process from an EU-based warehouse shipping within the EU. The reverse can also apply for orders entering the US, where sales-tax collection and marketplace rules may vary by state and selling channel.

Do not assume that a supplier’s quoted product or shipping price settles your tax obligations. Before launch, have an accountant or tax adviser review your specific flow, especially if you hold stock, use a local fulfilment service, sell through a marketplace or import goods in your own name.

  • Identify who is the importer of record for each route.
  • Ask whether tax is collected at checkout, at import or by another party.
  • Confirm which invoices and customs documents are supplied.
  • Check whether the supplier can provide the information your tax adviser needs.
  • Review registration, filing and marketplace obligations in every market you target.
  • Document the treatment of refunds, returned goods and replacement shipments.

Build a realistic lead-time model

A published dispatch estimate is only one part of delivery performance. Compare suppliers using the same sequence: order receipt, processing, warehouse handoff, carrier transit, customs clearance where relevant and final-mile delivery. A nearby warehouse can reduce border friction, but it does not automatically mean faster processing or better stock availability.

For cross-border routes, allow for customs queries, incomplete address data, public holidays and carrier handoffs. Record both a typical estimate and an exception plan so your customer promise is not based on the best-case route.

  • Processing time: how long from paid order to carrier handoff?
  • Transit time: which carrier and service level normally apply?
  • Border time: will the parcel cross a customs boundary?
  • Tracking: when is tracking created, and when does it begin updating?
  • Exceptions: who handles delays, lost parcels and address corrections?
  • Peak periods: what changes during holidays, promotions or seasonal demand?

Compare returns and customer support before launch

Returns can erase the apparent advantage of a lower product cost. A US customer returning an item to an EU location, or an EU customer returning an item to the US, may face longer transit, customs questions and higher postage. Ask for the operational process rather than relying on a general returns statement.

Clarify whether the supplier accepts returns, provides a local return address, offers replacements, or expects the retailer to resolve the issue directly. Also establish how damaged, incorrect or missing items are documented and reviewed.

  • Return address and eligible destinations
  • Return-window rules and required evidence
  • Responsibility for return postage
  • Replacement and refund workflow
  • Handling of refused or undeliverable parcels
  • Expected response channel and escalation process

Product and integration fit matters too

Regional location is only one selection criterion. The aggregated public records show broad coverage of dropshipping and wholesale: approximately 91% indicate dropshipping capability and 96% wholesale capability. By comparison, only small shares publicly indicate private-label, API, CSV or XML capabilities. If automation, custom packaging or product development is important, verify those capabilities separately rather than assuming they come with regional fulfilment.

Category mix also matters. Public records include significant coverage across fashion, electronics, lingerie, home and living, accessories, beauty, gifts, kids, toys and footwear. Compare the region, category, warehouse and operating model together; a large regional pool does not mean every supplier supports your required workflow.

  • Product category and compliance documentation
  • Stock-feed or catalogue format
  • Order submission and tracking workflow
  • Packaging and branding options
  • Minimum order or account requirements
  • Ability to test sample orders before launch

A practical US vs EU decision worksheet

Score each candidate against the same criteria and keep evidence for every answer. This avoids choosing based on headline shipping speed or product price alone. Use a simple weighted model that reflects your customers: for example, give more weight to delivery reliability and returns for a time-sensitive category, or to tax documentation and compliance for regulated products.

Before making a final decision, place test orders to representative destinations. Compare the dispatch location shown in tracking, packaging, documentation, delivery updates and the process for resolving an exception. This is more informative than a warehouse claim viewed in isolation.

  • Warehouse location by SKU and destination
  • Processing and transit estimates
  • Customs and tax responsibility
  • VAT or sales-tax documentation
  • Tracking quality and carrier coverage
  • Return route and replacement handling
  • Catalogue, stock and order integration capability50000? no

What to verify before contacting a supplier

Prepare a short route brief so every supplier receives the same questions. Include your target customer countries, product categories, expected order profile, required warehouse region and preferred integration method. The public directory can help you narrow the relevant supplier segment, while member access provides the supplier identities and contact details needed for direct comparison.

Tax and customs answers should be confirmed for your own business structure. Public supplier information can support research, but it is not a substitute for professional advice or written operational confirmation.

  • Which warehouse will fulfil each target destination?
  • What are the processing and delivery estimates for a test order?
  • Who is responsible for import, VAT or sales-tax collection?
  • What documents accompany the shipment?
  • How are returns, refunds and damaged goods handled?
  • Which catalogue, inventory and order formats are supported?

Frequently asked questions

Are EU suppliers always faster for EU customers?

No. An EU warehouse may reduce cross-border distance for some routes, but processing speed, stock location, carrier service and returns handling also affect the outcome. Confirm the dispatch warehouse and test the route for the products you plan to sell.

Does a US supplier handle VAT for EU orders?

Not necessarily. VAT and import responsibilities depend on the transaction and shipping structure. Ask who collects or accounts for tax, who is the importer of record and what documents are provided, then obtain advice for your specific business.

Is a supplier’s country the same as its warehouse country?

Not always. Registration or operating location does not prove where inventory is stored. Request warehouse information by product and destination, and check the dispatch origin on a test shipment.

Which is better for dropshipping: US or EU suppliers?

Neither is universally better. Choose the option that best matches your customer locations, product availability, tax setup, delivery expectations, returns process and integration needs. Aggregated records indicate broad dropshipping coverage, but capability must be confirmed for each supplier.

What should I test before listing products?

Place sample orders to representative customer destinations. Check processing time, dispatch origin, tracking updates, packaging, customs documentation, delivery completion and the response process for a return or delivery problem.
