Field guide / supplier verification

How U.S. buyers can verify an overseas supplier before ordering.

A supplier can look credible online and still be the wrong fit for your product, order, or risk profile. Use this guide to build a documented view of the business, the factory, the evidence, and the payment terms before money moves.

This is general information, not legal, customs, accounting, or financial advice. No verification step guarantees supplier performance, product quality, delivery, or compliance.

The verification line

Treat each check as one piece of evidence. The goal is not to prove a supplier is risk-free; it is to surface questions early enough to make a deliberate decision.

01

Start with the business behind the offer.

Ask for the supplier's legal name, registration details, operating address, direct contacts, ownership or operating history where available, and the entity that will receive payment. Compare those details across the quote, contract, website, email domain, product documents, and bank information. A mismatch is a question to resolve, not automatic proof of fraud.

Search more than the supplier's own website. Check whether the business exists in relevant registries or industry directories, whether the address describes an actual operating location, and whether the people communicating with you have consistent roles. The ITA due-diligence guidance is a useful starting point for thinking about country, company, and purchasing risk.

An online check is only preliminary. The U.S. Commercial Service background-check tips note that limited information, inconsistent contact details, and a superficial web presence can be warning signs, while a single red flag does not by itself establish that an entity is illegitimate.

02

Confirm who can make the product.

Establish whether you are dealing with a factory, a trading company, or a combination of both. A trading company may be the right partner for your order, but you should know who controls production, where the goods will be made, and which party is responsible for quality and documentation.

Ask for the actual production address and a clear description of the relevant equipment, processes, capacity, subcontractors, quality-control checkpoints, and traceability records. Compare the answer with your product specification: materials, tolerances, testing, packaging, labeling, and required documentation.

When the order justifies it, request a live video walkthrough or an independent site inspection. A visit can confirm that a location and process exist at a point in time; it cannot guarantee every future batch, reveal every subcontractor, or replace written specifications and production controls. The ITA International Company Profile is an example of deeper company research that may include references, interviews, and a site visit. It is not a service provided by FathomKite.

03

Ask for evidence you can test.

Request recent customer references with permission to contact them. Ask targeted questions about product consistency, communication, lead times, packaging, defect handling, and how the supplier responded when something went wrong. Do not treat a list of logos, testimonials, or screenshots as a substitute for a conversation.

Order samples that match the proposed production specification. Record what you approved: materials, dimensions, finish, color, labeling, packaging, test results, and documents. For a larger order, consider a small pilot before committing to full volume.

Define acceptance criteria before production begins and decide how nonconforming goods will be handled. A good sample shows what was sent for sampling; it does not prove that a later production run will be identical without process controls and inspection.

04

Make payment follow the evidence.

Keep the product specification, quantities, tolerances, packaging, delivery terms, inspection rights, and remedies in writing. Use staged payments tied to documented milestones where appropriate, and verify the beneficiary and bank details through a separate, trusted channel before sending funds. Treat any bank-account change as a new instruction that requires independent confirmation.

Consider whether inspection before final payment, escrow, a letter of credit, insurance, or another professional trade-finance arrangement fits the transaction. Each option has conditions, costs, and limits; none is a universal guarantee. The ITA Trade Finance Guide explains several payment methods and documentary requirements so you can discuss the tradeoffs with your bank or qualified adviser.

For U.S.-bound goods, keep supply-chain visibility in view as part of your broader importer review. The CBP Forced Labor FAQs provide compliance context; they are not a substitute for legal advice about your particular goods, suppliers, or obligations.

Before the first order

Put the open questions on one page.

Save the evidence you reviewed, the questions still open, and the person responsible for resolving each one.

  • Identity

    Match the legal entity, registration details, address, contact details, website, and bank beneficiary across the documents you received.

  • Capability

    Confirm the production address, relevant equipment and processes, quality controls, and who will actually make the order.

  • Evidence

    Speak with permitted references, order a sample or pilot, and write down acceptance criteria before production.

  • Payment

    Document milestones, independently verify payment instructions, and decide whether an inspection or trade-finance instrument fits the risk.

Red flags worth slowing down for

  • Pressure to pay quickly or bypass an agreed review step.
  • Inconsistent company names, addresses, domains, documents, or beneficiaries.
  • References that cannot be independently reached or will not answer specific questions.
  • Refusal to show the production site or explain who will make the goods.
  • An unexplained bank-account change sent by email or chat.
  • A request to bypass written specifications, inspection terms, or documented approvals.
Sources and boundaries

Use the guide as a starting point, not a clearance stamp.

Source links were reviewed October 6, 2026. Government guidance can change, and the right checks depend on the product, country, transaction, and parties involved. This guide is general information only, does not create an adviser-client relationship, and does not guarantee a supplier or transaction outcome.
