China Sourcing Agent: What They Do, What They Cost and How to Choose One

A China sourcing agent, also called a buying agent or purchasing agent, represents you in front of factories: they shortlist manufacturers, check that each one exists and can actually make your product, negotiate, follow production and inspect the goods before they ship. How much does a sourcing agent cost? On commission, most charge between 5% and 10% of the value of the goods; others work for a flat fee or a retainer. But the rate is the wrong first question. The right one is: who pays the agent, and therefore whose side are they on?

This guide compares sourcing agent fees and types of intermediaries, lists the red flags and the questions to ask, then walks through what the contract should say. For the supplier search process itself, see how to find and qualify a supplier in China.

What does a China sourcing agent actually do?

Scope varies from one agent to the next, which is exactly why it needs to be in writing. A full engagement usually covers:

• Supplier search: B2B platforms, trade shows, industrial clusters and personal networks, to put several manufacturers that genuinely specialize in your product in front of you.
• Vetting: business license, China's official company registry, a visit or a factory audit.
• RFQ and negotiation: one identical request for quotation sent to every candidate, quotes compared line by line, then negotiation of price, minimum order quantity (MOQ), payment terms and mold ownership.
• Samples: managing revisions until a signed reference sample (the golden sample) is approved.
• Production follow-up: schedule, materials, milestones, early warning of delays.
• Quality control: inspections before, during and after production, on a sample drawn under ISO 2859-1 or its US counterpart ANSI/ASQ Z1.4 (see pre-production, in-line, pre-shipment and loading inspections).
• Logistics coordination: export documents, consolidation, booking freight with a forwarder.

Some intermediaries also pay suppliers on your behalf. That is convenient, provided you see the factory's invoices; otherwise you no longer know what you are paying, or to whom.

One legal distinction matters: does the agent act on your behalf (you buy from the factory and they represent you), or do they buy the goods and resell them to you? In the second case they are a reseller, whatever they call themselves. That changes your visibility on price, your recourse and even your customs value.

How much does a sourcing agent cost? Fee models compared

Going by the rate cards many agents publish, commissions most often fall between 5% and 10% of the value of the goods: higher on small orders, lower on large volumes. The rate alone tells you little. Compare what it covers and what it is calculated on.

Extras matter as much as the rate: samples, lab testing, travel, additional inspections, bank charges. Ask for them to be passed through at cost, with receipts. And think in landed cost rather than unit price: see how to calculate the landed cost of an imported product.

"Free" sourcing: who really pays?

An agent who charges you nothing is being paid by someone: the factory, through a kickback built into your price. That agent has every reason to steer you toward the factory that pays them best rather than the best factory, and to play down the defects they find.

Buying commissions and customs value

Independent agent, sourcing company, trading company or DIY?

Four ways to buy from China, four different trade-offs between visible cost, transparency and security.

An independent agent is often bilingual, responsive and inexpensive. The limits: one person covering search, negotiation, follow-up and inspection; rarely any setup for truly independent quality control; sometimes no company at all to invoice you or answer for a mistake. Check that they operate through a registered entity and invoice you properly.

A trading company buys from factories and resells to you. It is useful for small volumes or assortments drawn from several workshops, and it handles export. In exchange, you pay a markup you cannot see and lose traceability: at the very least, find out which factory makes your goods and have it audited.

A sourcing company has teams on the ground, written procedures and a service agreement. On paper it costs more than a freelancer; it has to earn that through transparency (visible supplier invoices), independent inspections and continuity.

Going it alone makes sense for a simple product if you have the time, can travel and know each step well. The real cost is then measured in weeks of work, failed samples and unmanaged risk.

Red flags when choosing a sourcing agent

Kickbacks are not only an economic problem. In the UK, the Bribery Act 2010 covers private-sector bribery, including advantages offered or accepted so that someone performs their role improperly, and many US states have commercial bribery statutes of their own. Whatever the jurisdiction, ban kickbacks in writing and keep a right to audit.

One last trap is bank detail fraud: an email, sometimes sent from a real supplier's hacked mailbox, announces a new account. The FBI's Internet Crime Complaint Center recorded about $3.05 billion in reported losses from business email compromise in 2025. The UK's National Cyber Security Centre advises confirming any unusual payment request through a second channel, such as a phone call to a number you already have.

Questions to ask before you sign

1. How are you paid, and do you receive anything at all from factories? Get the answer in writing.
2. Which entity do you operate through, in mainland China or Hong Kong? Can you send me its business license or registration certificate?
3. Will you give me each factory's legal name, address and business license, along with its invoices?
4. Who performs inspections, using what method, and can I see a sample report?
5. Who pays suppliers, into which accounts, and how do you verify a change of bank details?
6. How many projects do you run in my product category? Can I speak to two current clients?
7. What happens when a lot fails inspection: re-inspection, who bears the cost, finding another factory?
8. Who owns the supplier list, the samples, the molds and the files?
9. How will I be kept informed: reports, photos, a shared tracking tool?
10. How do we end the relationship, and what do I get back?

How the agent answers matters as much as what they say: a good agent replies in writing, quickly and precisely, with documents to back it up.

What a sourcing agent contract should include

An email thread is not a contract. The agreement, or the agent's terms of service, should cover at least the following.

The agent agreement does not replace the one with the factory (NNN agreement, mold ownership, penalties): see how to protect your intellectual property in China. Have the whole package reviewed by a lawyer; this guide is not legal advice.

DIY or full-service sourcing?

Nothing stops you from buying from China on your own: platforms put thousands of factories a few clicks away. What costs money is everything else.

• Time: search, RFQs, samples, production follow-up and logistics add up to several weeks of work spread over months, across a 7- to 16-hour time difference.
• Skills: reading a Chinese business license, writing a technical specification, negotiating tooling, applying an AQL sampling plan.
• Presence: defects are found at the factory before the balance is paid, not when the container is opened in Los Angeles or Felixstowe.
• Hidden costs: travel, failed samples, lots that need re-sorting, a delay that misses a season.

A poorly chosen agent adds risk instead of removing it. That is why NOVASEA operates as a transparent sourcing company, with a step-by-step method executed against your specification:

1. A precise specification, written with you and translated into Chinese where it matters.
2. Vetted factories: license and registry checked, a visit or a factory audit before you order.
3. Solid negotiation and contracts: price, payment schedule, molds in your name, an NNN agreement.
4. Independent inspections with photo reports, before the balance is paid (quality control).
5. Consolidation in China, as close as possible to your factories, with a single container leaving China; customs clearance coordinated with our licensed partners (logistics).
6. One point of contact, and your whole project visible in NOVASEA Bridge: milestones, reports, documents, shipments.
