How do I write a sourcing agent contract (anti-kickback clause)?
Short Answer: Require Disclosed Fees, No Factory Markup, Factory-Contact Rights, Blind Inspection, and an Anti-Kickback Clause With Penalties
A solid sourcing-agent contract protects you from the two real risks: hidden margin and kickbacks. Must-have clauses are a separately disclosed agent fee with any factory-price markup prohibited; the right to contact the factory directly and receive the original invoice; the right to unannounced blind inspection by an independent firm; and an anti-kickback clause stating the agent may not accept supplier rebates and, if they conceal defects for a kickback, forfeit commission and pay penalties. Add clear delay-compensation and quality-refund terms. An honest Yiwu agent welcomes this contract because it filters out dishonest competitors - refusal to sign is itself a red flag.
The Two Real Risks
Most agency problems are not theft - they are quiet margin. A dishonest agent marks up the factory price and pockets the difference, or takes a rebate from a supplier to steer your order regardless of quality. The contract exists to make both visible and expensive to attempt.

Must-Have Clauses
The core clauses are few but non-negotiable. Together they mean you can see the real factory price, check it independently, and punish any attempt to hide margin or take a rebate.
| Clause | What it does | Why it matters |
|---|---|---|
| Fee disclosed separately | Agent's cut shown | No hidden spread |
| No factory-price markup | Prohibited in writing | You see true cost |
| Factory-contact right | You may call the factory | Verification |
| Original invoice access | Factory bill to you | Proof of price |
| Blind inspection allowed | Unannounced, independent | Quality check |
The Anti-Kickback Clause Specifically
This is the clause that changes behaviour. It states the agent may not accept rebates from any factory, and if they conceal a defect to protect a supplier's kickback, they forfeit their commission and pay a penalty. Put a number on the penalty so it is not symbolic - a clause with no cost is just a wish.

Delay and Quality Refund Terms
Beyond margin, the contract should cover time and defects: delay-compensation if the shipment misses the agreed date, and a quality-refund or replacement path if goods fail inspection. These give a dispute a baseline so a claim is not a negotiation from zero.
State the delivery date
With a penalty per week late.
Define the quality bar
Reference the approved sample and AQL.
Name the remedy
Repair, replace, or refund.
Say who pays re-inspection
Usually the agent if they failed.
Keep it in writing
Verbal terms do not enforce.
An Honest Agent Welcomes This
A transparent Yiwu agent has no reason to fear a tight contract - it only disadvantages dishonest competitors. If an agent pushes back on disclosed fees, factory contact or blind inspection, treat that resistance as the answer. The contract is a filter, and a good agent is happy to be filtered through it.
- Refuses disclosed fee Why hide it if it is fair?
- Blocks factory contact What are they protecting?
- Won't allow blind inspection Confidence problem.
- Signs without hesitation The signal you want.

Case: The Rebate That Cost the Commission
The contract carried an anti-kickback clause with a stated penalty. Mid-year the agent was found to have steered a brush order to a higher-priced factory for a rebate. The concealment was caught at blind inspection.
