For many first-time buyers sourcing from 1688.com or directly from Chinese factories, the biggest fear is paying for an order only to receive sub-standard products—or worse, having the supplier disappear entirely.
Many importers believe that a Proforma Invoice (PI) is enough to protect them. In reality, a standard English PI is often little more than “scrap paper” in the eyes of Chinese law. To truly ensure the safety of your goods, you must draft a legally binding local Chinese purchase contract.
As professional sourcing agents, mychinamate provides custom-tailored Chinese contracts. Suppliers are much less likely to risk sending defective goods when a local agent is involved. Our comprehensive quality control services ensure your investment remains safe.

Why Your English Contracts and PIs Often Fail
When you are overseas without a local office, your relationship with the supplier is a distant one. Suppliers are local taxpayers, and without a third party to document evidence, an English-language contract can lead to endless delays in local courts until you simply give up.
By involving a third party like mychinamate, we create a documented chain of evidence during inspection and draft a Chinese-language contract. Suppliers are far less likely to take risks when they know a local agent can initiate legal action immediately.
How a Local Chinese Contract Protects Your Investment
1. Verifying the Supplier’s Legal Entity
Many suppliers use entities that are not actually owned by the factory boss. If the legal entity is not clearly identified, the factory can simply deny the debt.
- The Solution: The Chinese contract must clearly state the full Chinese name as it appears on the supplier’s official business license.
- The Red Chop: Most importantly, the contract must be stamped with the supplier’s official red company seal (Chop), which must match the business license exactly.
2. Precise Product Descriptions
Generic terms like “high quality” allow suppliers to make excuses. We define quality with absolute precision, including:
- Pantone color codes and material specifications.
- Detailed packaging descriptions and dimensions.
- Surface finish requirements and a strict list of “non-acceptable” defects.
By “locking in” these specifications, we eliminate the room for disputes.
3. Strict Delivery Timelines
Factories often over-promise and under-deliver, causing you to miss peak sales seasons. Our contracts include a “penalty ladder”:
- Example: A 1% deduction of the total value for every day of delay.
- The buyer retains the right to cancel the order and demand a full refund of the deposit if a specific grace period is exceeded.
4. Linking Payment to Quality Control (QC)
Never pay 100% upfront without seeing the final products. The industry standard is a 30% deposit and 70% balance.
- The Clause: Our contracts state that the 30% deposit starts production, but the remaining 70% is only payable after the goods are finished and 100% pass inspection by mychinamate’s on-site team.
Protecting Your Designs: NNN Agreements vs. NDAs
If you are developing a custom product (OEM/ODM), a Western NDA (Non-Disclosure Agreement) is largely unenforceable in China. You need a Chinese NNN Agreement:
- Non-Disclosure: Prevents the factory from sharing your design.
- Non-Use: Prevents the factory from using your design to sell the product themselves.
- Non-Circumvention: Prevents the factory from bypassing you to sell directly to your customers.
The Ultimate Defense: Why You Need a Local Sourcing Agent
Signing a contract is only the first step; executing it is the real challenge. If you are thousands of miles away, who will verify the “Red Chop” or monitor the assembly line?
This is why global buyers choose mychinamate:
- Local Legal Support: we use local legal knowledge to sign contracts that actually intimidate dishonest suppliers.
- Supply Chain Due Diligence: We physically verify licenses and factory capacity before you sign.
- On-site Pressure: When deadlines slip or quality dips, we are the ones “banging on the table” at the factory to demand a redo.
Don’t let your international sourcing become a gamble.
