What Chinese Supplier Agreement agreements hide in plain sight
The most common red flags we catch in this contract type.
A Western-style NDA is not reliably enforceable in PRC courts — an NNN drafted under Chinese law is what actually protects your design.
The supplier's job effectively ends once goods are loaded — everything after that, including damage or loss in transit, is on you.
Without an AQL standard, inspection right, and a defined rework or refund obligation, you eat the cost of every bad batch.
No tariff clause means duty hikes after your PO — including today's 30-54% US–China rates — come out of your margin.
The three things that decide whether your Chinese Supplier Agreement holds up
A Chinese supplier contract is not a Western contract translated into English. Enforcement in the People's Republic of China depends on three things almost every founder gets wrong: the contract must be drafted under Chinese law, the exclusive jurisdiction must be a PRC court where the supplier is located, and the controlling language must be Chinese. A pristine US-style NDA signed with a Shenzhen factory is, in practice, an unenforceable letter of intent.
The single most expensive failure mode is IP leakage — the factory quietly starts running your tool at night, or sells your product to a competitor through a sister entity. The Western NDA cannot stop this because it does not prohibit non-use or non-circumvention, only disclosure. A properly drafted NNN (Non-Disclosure, Non-Use, Non-Circumvention) under Chinese law with liquidated damages built in is what actually creates deterrence.
The second failure mode is quality: no defect-rate cap, no inspection right, no obligation to rework. We check for an AQL standard (typically 2.5 for majors, 4.0 for minors), an inspection right before shipment, and a defined remedy that gives you rework, replacement, or refund at your election — not the factory's.

Red flags we see in real Chinese Supplier Agreements
Specific patterns to check for before you sign — with the fix for each.
Almost every supplier will send a document titled 'NDA' or 'Confidentiality Agreement' in English. Real NNNs are bilingual, PRC-law governed, and specifically prohibit use and circumvention.
FOB requires a named port and shifts risk at ship's rail. Vague 'FOB China' or 'FOB nearest port' turns FOB into effectively EXW — you carry risk from the factory floor.
The correct trigger is a BL copy or a passed pre-shipment inspection — not the supplier's word that goods are ready.
A HK, Singapore, or US court judgment against a mainland Chinese factory is not directly enforceable. You need a PRC court where the supplier has assets.
How to negotiate a Chinese Supplier Agreement
The concrete asks we recommend, in the order to raise them.
- 1Insist the master agreement is bilingual with Chinese as the controlling language
- 2Move governing law to PRC and jurisdiction to a PRC court at the supplier's registered address
- 3Replace the NDA with an NNN including liquidated damages (typically 3-5x order value per breach)
- 4Peg the balance payment to a passed third-party inspection report, not shipment
- 5Add a defect-rate cap using AQL 2.5 / 4.0 with rework or refund at buyer's election
- 6Push tariff / duty risk to the supplier for their own misclassifications
Here's what your report looks like
Plain English. No legal jargon. Action you can take today.
A Western-style NDA is not reliably enforceable in PRC courts — an NNN drafted under Chinese law is what actually protects your design.
The supplier's job effectively ends once goods are loaded — everything after that, including damage or loss in transit, is on you.
Without an AQL standard, inspection right, and a defined rework or refund obligation, you eat the cost of every bad batch.
A single mis-drafted supplier contract can wipe out a full year of margin. The typical FBA-scale disaster looks like this: 30% deposit wired, tooling paid for, first shipment arrives with a 12% defect rate and no rework clause, the factory blocks further communication, and the foreign-court jurisdiction clause makes recovery uneconomic. Six months later a lookalike appears on Amazon shipped by a sister entity of the same factory. Both outcomes were preventable in the first 60 seconds of the contract review.

Frequently asked questions
What is an NNN agreement?
Three protections in one — Non-Disclosure, Non-Use, Non-Circumvention. Unlike a standard NDA, NNN agreements are structured to be enforceable in Chinese courts where your supplier operates.
What Incoterms should I request?
DDP gives you the most protection — supplier bears all risk until goods arrive at your location. FOB transfers risk early. EXW transfers risk at the factory gate — worst for overseas buyers.
How do tariffs affect my contract?
No tariff clause means you absorb 100% of duty increases after placing your order. With US–China tariffs at 30-54%, this can destroy your margin on a single order.
