Payment Terms in China Sourcing: T/T, L/C and Reducing Risk
How you pay matters as much as how much you pay. This guide explains the common terms — 30/70 T/T, letters of credit and milestone payments — where the risk really sits in each, the red flags worth walking away from, and how to stage payments so your money follows verified quality.

TL;DR — Key Takeaways
- A 30% deposit plus 70% before shipment, paid by telegraphic transfer, is the most common default. It balances the supplier's need to buy material against your need to see goods before final payment.
- A letter of credit puts a bank between buyer and seller, releasing payment against compliant shipping documents. It costs bank fees and documentation discipline.
- The real risk in any term is who holds the leverage at the moment money moves. 100% upfront hands all the leverage to the supplier.
- Milestone payments — deposit, tooling, first-article, balance against inspection — tie each transfer to a verifiable event and keep the largest sums behind a quality gate.
The Standard Terms You Will See
Most quotes from Chinese suppliers start with the same shape: a deposit by telegraphic transfer (T/T) to fund raw material and production, then the balance before shipment. The familiar version is 30% deposit and 70% before shipment. It is popular because it is fair in structure — the supplier is not financing your whole order, and you are not paying for goods you have not seen. What varies is the split: a new supplier may ask for a heavier deposit, while a repeat supplier with a good record may accept a lighter deposit or a balance against shipping documents.
The important detail hidden in 'before shipment' is exactly when the balance is due. If it is due before the goods leave the factory, your leverage disappears at the gate. If it is due against a copy of the bill of lading, the goods have at least been handed to the carrier. If it is due against a passed inspection, quality has been verified first. Each step along that chain shifts a little more security to you, and it is worth negotiating precisely rather than accepting the vague phrase at face value.
The deposit is a negotiation too. A supplier with real production capacity will usually tie the deposit to raw material cost, which is a fraction of the order, rather than to a round percentage of the full value. If a supplier insists on a heavy deposit without a material cost breakdown, ask for one. Seeing how the money maps to material, labour and tooling is a quick way to tell a genuine factory from one that is only passing the order along to someone else.
How a Letter of Credit Changes the Picture
A letter of credit (L/C) inserts a bank between the buyer and the seller. The buyer's bank issues a credit promising to pay the seller once the seller presents a defined set of documents that comply with the credit terms — typically an invoice, a full set of shipping documents, and any certificates the order requires. The seller gains a bank-backed assurance of payment; the buyer gains the assurance that payment is released against documents rather than against a promise.
The trade-off is cost and rigidity. An L/C carries bank charges on both sides and demands that the documents match the credit terms almost exactly; a small discrepancy can delay or block payment until it is resolved. That makes an L/C sensible for a large first order or a new relationship where both parties want a neutral mechanism, and less sensible for frequent small orders where the documentation effort outweighs the protection. Where you do use one, keep the terms simple and align the required documents with what your supplier can actually produce.
Payment Methods Compared
The table below compares the methods you are most likely to discuss. Read it as a trade-off between buyer security and supplier cash flow: the more security you gain, the more of the financing burden the supplier carries, which usually shows up in the price.
| Method | How It Works | Buyer Security | Supplier Cash Flow | Best Used When |
|---|---|---|---|---|
| T/T, 30/70 | Deposit to start, balance before shipment | Moderate | Good | Established relationship, small to mid-size orders |
| T/T, 100% upfront | Full payment before production | Poor | Excellent | Rarely; only small sample or tooling charges |
| Letter of credit | Bank pays against compliant documents | High | Moderate | Large first order or new supplier |
| Milestone / staged | Payments tied to deposit, tooling, first article, inspection | High | Moderate | Custom parts, tooling and critical quality |
| Open account | Goods ship, payment follows after agreed credit days | High | Poor | Long-term trusted supplier only |
Where the Risk Actually Sits
The label on the payment method matters less than the moment money moves relative to the moment you gain control of the goods. Ask one question of any term you are offered: at the instant I pay, what do I hold if things go wrong? A deposit paid to start production is money at risk, but it is small and it unlocks the order. A balance paid before the goods leave the factory removes your leverage just when you need it most. A balance released against inspection or shipping documents keeps some control until quality or dispatch is demonstrated.

Red Flags Worth Walking Away From
- 100% payment before production, especially for a new supplier. It hands all leverage to the seller. A deposit is normal; total prepayment for finished goods is not.
- Payment to a personal account or to a company unrelated to the contract. The account name should match the contracting company and the invoice. Anything else removes your ability to prove who you paid.
- Sudden changes to bank details, often sent by email late in the order. Verify any change by a second channel and a phone call to a known contact before money moves.
- Pressure to pay urgently to secure a price or a slot. Urgency is a classic lever to stop you checking. A fair supplier will wait for a properly verified payment.
- Reluctance to name a legal entity or to put the terms in writing. Payment terms belong in the purchase order, not in a chat. If the supplier resists a written contract, treat that as a signal.
Staging Payments by Milestone
For custom or tooled parts, a single 30/70 split often does not match how the work actually progresses. A better structure ties each payment to a verifiable event and delays the largest sums until quality is demonstrated. The shape below is a starting point to adapt, not a fixed formula.
- Deposit on PO — funds raw material and starts production. Keep it proportionate to the material cost, not to the whole order value.
- Sample and tooling payment — released only after samples are approved and before tooling is committed. Tie it to the drawing revision you signed off.
- First-article payment — follows dimensional and material verification on the first parts off the tool, before the full run.
- Balance against inspection — the largest payment is released after a passed pre-shipment inspection and, where agreed, against a copy of the shipping documents.

Tooling Payments and Ownership
Tooling is where payment disputes most often begin, because the money and the asset can drift apart. If you pay a tooling charge, the purchase order should say plainly that the tooling belongs to you, identify it specifically, and set out what happens if you move the work to another supplier — that it will be returned, or that a documented buyout applies. Without such a clause, ownership is ambiguous, and a supplier you have fallen out with holds a physical asset you believe is yours.

Conclusion
There is no single correct payment term, only the one that matches your leverage at each stage of the order. A 30/70 T/T split is a sound default for routine orders with a known supplier. A letter of credit buys bank-backed security for a large or unfamiliar deal, at the cost of fees and documentation discipline. Milestone payments are the strongest fit for custom and tooled parts, because they put the largest sums behind inspection and first-article approval. Whatever you choose, verify the payee, keep the terms in writing, and make the money follow verified quality.
