Questions in this part

Q31. Do I need the company chop? Is the manager’s signature enough?

Follow the agreement’s own effectiveness clause: if it says the agreement takes effect upon signature and chop, an authorised person must sign and the company must chop; if it says it takes effect upon chop alone, the chop alone suffices. As a matter of law, a signature by an authorised representative can bind the company even without a chop (Civil Code Art 490; SPC contract-book interpretation) — but the chop is the strongest evidence of the company’s assent and removes an argument before it starts. Use the contract chop or company seal (PSB-registered, name matching the agreement); financial and departmental chops do not bind; treat private or fake chops as red flags. When in doubt, do both: signature and chop.

Q32. Does a Hong Kong entity’s signature protect me?

No. Bind the actual mainland manufacturer — licence details and chop. Add the Hong Kong trader as an additional party if it is part of your transaction. The recurring failure: the CAD files sat with the unsigned mainland factory.

Q33. Can I send previews before the signed NNN is back?

Only watermarked or obscured previews, if anything. Full CAD/BOM/specifications go after execution. Even prototype photos pre-signing can be an unprotected implied disclosure.

Q34. I already sent files before signing — do I have protection?

Potentially: Civil Code Art 501 imposes negotiation-stage confidentiality duties even where no contract forms; and a later NNN can acknowledge prior delivery and regulate continued holding, use, return, and deletion. But you must prove what was shared, with whom, under what expectation, and the misuse — and the later agreement does not automatically turn past conduct into contractual breach. Freeze the evidence now.

Q35. Which seal counts?

The company seal or the contract chop . Financial chops and departmental chops generally do not bind the company to an agreement of this kind. Verify the chop’s form (round, red, star-centred) against the Public Security Bureau registration, and that the chop-holder is real.

Q36. How do I verify the supplier?

The National Enterprise Credit Information Publicity System / gsxt.gov.cn (registration, scope, legal representative, capital), China Judgements Online (litigation history), financial health and debt situation, physical address matching the licence, the chop-holder actually sitting in the building, signatory authority, and a blacklist check for prior IP violations. The background check costs trivially against the cost of IP theft.

Q37. How much should liquidated damages be?

Calibrated — within roughly 30% of your realistic loss (the SPC benchmark above which courts treat agreed damages as excessive and reduce them). Tie the number to something defensible: lost profits, market damage, development cost, or project value. Market practice shows per-breach figures in the tens of thousands of USD or low millions of RMB for meaningful projects; what survives challenge is the defensible relationship to harm, not the size.

Q38. What if liquidated damages are set too low?

Set the initial amount based on projected contract value and your bargaining position, and include a clause that the breaching party bears all liability exceeding the liquidated amount where actual loss is greater. A penalty too low is a cheap price to pay for breach — effectively a cheap licence.

Q39. Are high or punitive penalties enforceable?

Not at face value: courts reduce amounts exceeding roughly 30% over actual loss on request, and a number with no defensible relationship to harm is a reduction waiting to happen. The enforceable version is a liquidated amount with a loss rationale. There is also a market-reality check: the factory negotiates the number down; a huge number that survives negotiation only because the factory never intends to perform is worth little.

Q40. How much does a professionally drafted NNN cost?

Market ranges: USD 800–2,500 for a bilingual draft by China-qualified counsel; up to USD 1,500–5,000 for complex or multi-party mandates. Package pricing for multiple factories is common. Weigh that against one mould, one trademark class, one season of inventory.

Frequently asked questions

Do I need the company chop? Is the manager's signature enough?

Are high or punitive penalties enforceable?
Not at face value: courts reduce amounts exceeding roughly 30% over actual loss on request, and a number with no defensible relationship to harm is a reduction waiting to happen. The enforceable version is a *liquidated* amount with a loss rationale. There is also a market-reality check: the factory negotiates the number down; a huge number that survives negotiation only because the factory never intends to perform is worth little.
How much does a professionally drafted NNN cost?
Market ranges: USD 800–2,500 for a bilingual draft by China-qualified counsel; up to USD 1,500–5,000 for complex or multi-party mandates. Package pricing for multiple factories is common. Weigh that against one mould, one trademark class, one season of inventory.
