Payment disputes are one of the most common causes of broken relationships and lost money when foreign companies do business with Chinese suppliers. Even if you have a carefully written contract, disagreements over payment terms, deposit amounts, currency fluctuations, and quality claims can still turn into expensive, time-consuming disputes.
Based on our experience working with hundreds of international buyers and Chinese suppliers, we’ve identified the five most common payment disputes that happen in cross-border trade with China, and we’ll walk you through practical solutions to prevent them from happening, or solve them if they already arise.
1. Deposit Disputes: Supplier Refuses To Refund Unused Deposit After Order Cancellation
This is the most common payment dispute we see, and it usually goes like this:
- The buyer pays a 20%–30% deposit to secure production
- Something changes: the buyer cancels the order before production starts, the project gets delayed, or the supplier fails to meet the agreed delivery date
- The buyer asks for their deposit back, and the supplier refuses, claiming the deposit is non-refundable no matter what the circumstances
Why this dispute happens
Many Chinese suppliers operate with thin margins, and they often reserve production capacity and buy raw materials as soon as they get the deposit. If the order gets cancelled, they don’t want to absorb the cost of the raw materials or the lost production slot. On the other hand, many buyers believe that if production hasn’t started yet, they’re entitled to a full refund.
The root of the problem is almost always a vague contract that doesn’t clearly define what happens to the deposit in different scenarios. If your contract just says “30% deposit payable on order” and doesn’t explain refund conditions, you’re guaranteed to have a dispute if things go wrong.
How to prevent and solve it
Prevention: Clearly write the deposit refund policy into your contract before you pay any money:
- If the order is cancelled because the supplier fails to meet contractual obligations (like missing the delivery window by more than 30 days, or failing quality inspections), the supplier must refund 100% of the deposit within 15 business days
- If the buyer cancels before raw materials are purchased and production is scheduled, the supplier refunds 80%–90% of the deposit (keeping 10%–20% to cover administrative costs for reserving capacity)
- If the buyer cancels after raw materials are purchased, the supplier can deduct the actual cost of the raw materials from the deposit and refund the rest, within a set timeframe
If you’re already in a deposit dispute, the fastest solution is usually to negotiate a partial refund. Most suppliers would rather give you a partial refund than go through arbitration or litigation, and they can usually resell the raw materials or production slot to another buyer. If the supplier refuses to negotiate any refund, you can escalate to international arbitration if your contract has an arbitration clause, or use a local mediation service in the supplier’s home province.
2. Exchange Rate Fluctuation Disputes: Supplier Demands Extra Payment Because The Renminbi Appreciated
This dispute has become much more common in recent years as the USD/CNY exchange rate has become more volatile. It typically happens when:
- You sign a contract denominated in US dollars, with a fixed price
- The Chinese renminbi appreciates 5% or more against the US dollar between the time you sign the contract and the time you make payment
- Your supplier says their costs in RMB have gone up, and demands that you pay extra to cover the difference
Why this dispute happens
Most small and medium-sized Chinese manufacturers price their products based on their costs in renminbi, then convert to US dollars for the contract price. If the RMB appreciates significantly, their actual revenue in RMB is lower than they expected, which can turn a profitable order into a loss.
Many older contracts don’t include any exchange rate adjustment clauses, so when big swings happen, suppliers try to pass the cost onto buyers. Even though it’s a breach of contract to change the price after signing, many suppliers will still demand extra payment, and threaten to hold your order hostage until you pay.
How to prevent and solve it
Prevention: Add a simple exchange rate adjustment clause to your contract:
“The contract price is fixed in US dollars. If the USD/CNY exchange rate moves more than 3% from the exchange rate on the contract signing date, either party can request a proportional adjustment to the contract price to reflect the exchange rate change.”
This clause is fair to both sides: it protects the supplier from big RMB appreciation, and it protects you from big RMB depreciation (if the RMB drops, your price drops too). Most reasonable suppliers will agree to this clause, because it reduces their risk as much as it reduces yours.
If you’re already in this dispute and you don’t have an adjustment clause, the best solution is usually to split the difference. If the exchange rate moved 5%, agree to a 2.5% price adjustment. This is cheaper than going through arbitration and delaying your order, which would cost you more money in lost sales than the price adjustment.
If the supplier is demanding a big adjustment and you have a clear fixed price contract, you can stand your ground – most suppliers know they’re in the wrong, and they won’t actually risk arbitration over the issue.
3. Quality Claim Deduction Disputes: Buyer Withholds Final Payment Because Of Product Quality Issues
This is the second most common dispute, and it usually works the other way from the deposit dispute:
- The buyer receives the goods, finds defects, quality issues, or that the product doesn’t match the contract specifications
- The buyer withholds all or part of the final payment to cover the cost of rework or discounts needed to sell the defective product
- The supplier demands immediate full payment, and claims the quality issues are either the buyer’s fault or exaggerated
Why this dispute happens
Most international trade with Chinese suppliers uses 30% deposit up front, 70% final payment against the bill of lading (B/L), or 70% paid after delivery. The problem with the first model is that the buyer pays the full balance before they even see the product – if the product is defective, they already have all their money at risk. In the second model, the supplier has already delivered the product, so they have no leverage to get paid if the buyer withholds payment.
The quality standard is often vaguely defined in the contract, so the buyer thinks the issue is a major defect that justifies a price deduction, and the supplier thinks it’s a minor cosmetic issue that doesn’t affect performance.
How to prevent and solve it
Prevention: The best way to prevent this dispute is to use an escrow service or a staged payment schedule that protects both sides:
- 20%–30% deposit when the order is placed (to cover raw material costs)
- 50%–60% paid when production is complete, after a third-party pre-shipment inspection confirms the product meets quality standards
- 10%–20% balance payment held back for 30–60 days after delivery, to be released only after the buyer has inspected the product and confirmed it meets specifications
Also, clearly define your quality standards in the contract, with acceptable defect rates, testing methods, and what deductions are allowed for different types of defects.
If you’re already in the dispute, the solution depends on who’s in the right. If the quality issues are real and documented with photos and third-party inspection reports, you have the upper hand. Most suppliers will agree to a reasonable partial deduction to settle the dispute, rather than going to court. If the quality issues are minor, it’s usually better to negotiate a smaller deduction and pay the balance to maintain the relationship.
Before you make any final decision on a dispute, you should always check if your supplier has a history of quality disputes with other buyers. You can get this information from a standard Chinese business credit report, which will show any pending or resolved legal cases related to product quality.
4. Letter Of Credit Dispute: Bank Rejects Documents Because Of Discrepancies
For many large orders, buyers use an irrevocable letter of credit (LC) to pay the supplier, which is supposed to eliminate payment risk for both sides. But LC disputes are surprisingly common, and they usually look like this:
- The supplier ships the product and presents the shipping documents to the advising bank
- The issuing bank finds minor discrepancies in the documents (like a typo in the beneficiary name, a wrong invoice number, or a bill of lading that says “clean on board” but has a minor notation)
- The bank rejects the documents and refuses to pay, and the buyer won’t agree to waive the discrepancies
Why this dispute happens
Banks strictly follow the “principle of strict compliance” for letters of credit – any discrepancy, no matter how minor, gives the bank the right to reject the documents and refuse payment. Many small and medium-sized Chinese suppliers don’t have experienced document preparation staff, so they make small mistakes all the time.
Sometimes the buyer will also instruct the bank to find discrepancies on purpose if they no longer want the goods (for example, if the market price dropped after they signed the contract).
How to prevent and solve it
Prevention:
- Agree in advance which bank will be the advising bank, and make sure the supplier has experience working with that bank
- Ask the supplier to send a full set of document drafts to you before they issue the original documents, so you can check for discrepancies in advance
- If there are minor discrepancies that don’t affect the actual shipment or product quality, agree in advance that you’ll waive minor discrepancies that don’t change the substance of the shipment
If you’re already in an LC dispute, you need to decide whether the discrepancy is material or just a typo. If it’s just a minor mistake that doesn’t affect your ability to clear customs or take ownership of the goods, waive the discrepancy and accept the documents – the supplier did everything right by shipping the correct product on time, so they’re entitled to payment.
If the discrepancy is material (for example, the wrong product description, incorrect quantity, or wrong port of loading), you have every right to reject the documents and withhold payment until the issue is fixed.
5. Hidden Fee Disputes: Supplier Adds Extra Fees After Price Is Agreed
This is a frustratingly common dispute, especially with smaller and less experienced suppliers:
- You agree on an all-in price (like FOB Shanghai $1.20 per unit)
- After you sign the contract and pay the deposit, the supplier starts adding all kinds of extra fees: “raw material surcharge”, “documentation fee”, “container stuffing fee”, “port security fee”, etc.
- They demand you pay these extra fees before they ship the goods, or they threaten to not release the B/L
Why this dispute happens
Many small Chinese suppliers deliberately quote a low price to win the order, then add hidden fees after the buyer is already committed. Other times, they’re just inexperienced and don’t know what all the actual costs are when they quote you the price, so they pass unexpected costs on to you.
Under incoterms like FOB and CIF, most of these fees are already supposed to be included in the supplier’s price. But suppliers still try to charge them extra to make more profit.
How to prevent and solve it
Prevention: When you agree on a price, explicitly write in the contract that the price is all-inclusive under the agreed incoterm, and list all the fees that are included. For example, if you’re doing FOB Shanghai, your contract should say:
“Price is FOB Shanghai, all-inclusive of raw material costs, manufacturing costs, inland transportation to Shanghai port, terminal handling charges, documentation fees, and packing costs. No extra fees will be charged beyond the contract price.”
This leaves no room for argument later.
If you’re already facing hidden fees, check your incoterms – almost all hidden fees that suppliers try to charge are already included in the FOB/CIF price according to the official ICC incoterm rules. If the fee is clearly the supplier’s responsibility under the incoterm, you can refuse to pay. If the fee is legitimate (for example, you changed the order after signing, which added extra costs), negotiate a fair split.
If the supplier refuses to ship unless you pay the extra fees, you can use the threat of legal action or bad credit reporting to push them to back down. Most suppliers don’t want a negative credit entry that will scare off future buyers, so they’ll back down rather than have the dispute recorded on their credit file.
General Tips To Avoid Payment Disputes Altogether
Most payment disputes don’t happen because one side is deliberately trying to cheat the other – they happen because the contract is vague, expectations aren’t aligned, and neither side took the time to clarify key terms before signing. You can avoid 90% of common payment disputes by following these simple rules:
- Get everything in writing: Don’t rely on verbal agreements made over WeChat or email. Put all payment terms, deposit refund rules, exchange rate clauses, and quality standards into a signed written contract.
- Do your due diligence before you pay: Before you send any money, verify that your supplier is a legitimate registered company, and check their history of past disputes. A $100 credit report can save you from losing a $100,000 order. Check ChinaBizInsight’s range of business verification reports to get the information you need.
- Use a payment structure that protects both sides: Avoid paying 100% up front, and avoid putting 100% of the risk on the supplier. Staged payments with third-party inspection are the best way to keep both sides honest.
- Negotiate first, escalate later: Most disputes can be solved with a reasonable compromise that saves both sides time and money. Escalate to arbitration or litigation only when the other side refuses to negotiate in good faith.
By understanding these five common disputes and putting preventative measures in place, you can drastically reduce your risk of running into a costly payment fight with your Chinese supplier, and build a more stable, long-term business relationship.
