Paid in Full, Goods Withheld: How a Bilingual Demand Letter Fixed It in a Week

An anonymized real case handled by our office. Details are changed or summarized to protect the parties; the strategy, the legal reasoning, and the outcome sequence are as they happened.

The short version: a French buyer paid in full for two excavators from a Chinese supplier. The supplier refused to ship, then demanded more than USD 10,000 in last-minute surcharges. After the evidence was locked, one bilingual demand letter — for a modest fixed engagement fee — and the buyer paid nothing further and recovered all goods within the week.

The deal

A French buyer found a Chinese supplier on a global sourcing platform, moved the negotiation to WhatsApp, and agreed to buy two excavators. The machines were specified as brand new, FOB Shanghai, for a mid-five-figure USD price. To be careful, the buyer flew to China, inspected the machines at the manufacturer's yard, photographed the nameplates and hour meters — all normal, about ten hours on the clock. Then he paid in full, in two instalments.

Money paid. Time to ship.

What happened next

The delivery date slipped — the promised custom extended arm took nearly three weeks. Then, the day the final payment landed, the machines "changed":

  • The supplier said the displays were Chinese-only, and English would cost thousands of dollars more per machine.
  • It suggested removing the DPF emission filter — mandatory in Europe; removing it makes the machines illegal to operate there. The buyer refused in writing on the spot.
  • Then the supplier itself sent a photo: the two "brand new" machines showed over fifty hours on their hour meters.

Confronted, the salesperson's answer on WhatsApp: "That's totally normal — other customers came to test-drive them before selling to you." And then the line that mattered most: "If the hours don't pass customs, we can adjust the meter to whatever number you specify."

From a lawyer's perspective, that message was a gift: the supplier had put its own breach — and its own willingness to tamper — in writing.

The strategy: evidence first, letter second

The instinct of most buyers at this point is to fire off a lawyer's letter immediately. We deliberately did not.

A demand letter is an open card. Once served, the supplier knows you mean business — and the typical response is to move the goods, go quiet, and change the facts on the ground. In this case the supplier had already been tipped off that lawyers were involved. Sending the letter then would have been a heads-up, not a demand.

So the plan was eight words: lock the evidence, then show the letter.

When the buyer's representative went to the supplier's premises, he carried three things: a color-printed demand letter (sealed, not yet served), an evidence checklist, and a recording phone. On arrival:

  • Recording started on entry.
  • He asked for the business license — companies in China must display it at their place of business; if refused, he photographed the premises.
  • Both machines were photographed in full: machine, nameplate, hour meter. All attachments and third-party goods were inventoried.
  • A few casual questions turned the key facts into the supplier's own words on the spot: "What about the 52 hours?" "No payment, no shipment?"

Evidence locked. Only then did the letter go over the table.

What was in the letter

The letter was drafted in the office, in the bilingual format we use for cross-border matters: Chinese as the operative legal text, English line by line, with every cited statute followed by a plain-language explanation of what it means. A Chinese supplier's managers shouldn't be able to claim they didn't understand, and the buyer should never be in the dark about what his own lawyer wrote.

It was not an emotional outburst. It pinned three legal points:

  • Unilateral price hikes don't bind you. The supplier's surcharges beyond the agreed price violated Article 543 of the Civil Code of the People's Republic of China — contract modification requires mutual agreement; a one-sided price increase has no effect on the buyer.
  • The goods didn't conform. Machines with fifty-plus hours did not match the "brand new" specification, violating Article 615 of the Civil Code and, because both China and France are contracting states, Article 35 of the United Nations Convention on Contracts for the International Sale of Goods (CISG), which applied directly to the sale.
  • The company structure was the weak spot. The supplier was a one-person company. Under Article 23, paragraph 3 of the Company Law of the People's Republic of China (revised 2023), a sole shareholder who cannot prove his property is independent of the company's bears joint and several liability for its debts. In enforcement, the hardest problem is usually finding property — this clause hands the creditor a second pocket to reach into.

The letter gave the supplier seven days and three demands: rescind the additional invoice and waive all extra charges; deliver the goods with EU-compliant nameplates and documents, free of charge; and confirm in writing. It closed with arithmetic — a realistic estimate of what litigating would cost in court fees, preservation, notarization, travel, and counsel. In plain words: if you want to keep score, we'll keep score — and the math won't end in your favor.

The day it resolved

On the agreed day, the representative was on site. Even after the letter, the supplier held out: "Pay part of the surcharge. License? No."

Three conditions had now converged at once: refusal to show identity, refusal to deliver, and broken negotiations. This was the red line agreed in advance — so the final step was taken: police were called.

The legal basis was straightforward: withholding all goods while refusing to identify the company could cross into contract fraud (Article 224 of the Criminal Law of the People's Republic of China). Having the police verify the identity of the entity was not a bargaining stunt — it was the lawful remedy for a party whose counterparty refused to be identified.

Five hours, three sides, one question at the core: are you actually this company? Bluster, excuses, and delay eroded under the police's verification. At hour five, the supplier signed:

Zero extra payment. All goods returned within the week.

The buyer's own summary, sent afterward: "We spent 5 hours with the police and reached an agreement — I pay nothing more and recover all goods this week."

Why it worked — the honest breakdown

  • The evidence was locked before the letter was served. 1,200+ WhatsApp messages, two invoices, payment records, the supplier's own hour-meter photos, the additional invoice — every breach was backed by the supplier's own written words. The letter just reordered those admissions into a claim.
  • We didn't send the letter early. A day earlier, the supplier could have moved the goods and gone dark.
  • The entity was pinned. The supplier's refusal to show its license made us push harder, not softer — without a confirmed legal person, neither the police call nor any lawsuit has a target.
  • The police were used sparingly, and lawfully. Not a negotiating chip; a remedy for a counterparty who refuses to be identified while holding your goods.

None of this guarantees the same outcome in another case. Every dispute has different facts, documents, and people. What transfers from this case is the method: organize the facts, verify the entity, lock the evidence, sequence the pressure, and keep the arithmetic on the table.

What a buyer should take from this

  1. Above a few tens of thousands of dollars, don't rely on a proforma invoice alone. A PI is a quote, not a contract. Quality standard, inspection window, delivery terms, breach liability, dispute resolution, governing law — put them in a real contract. (Contract review is exactly for this.)
  2. Don't leave the platform. This deal moved from the sourcing platform to WhatsApp plus a payment route outside the platform — and with it went the platform's escrow, complaint channels, and evidence trail.
  3. A one-person company deserves extra caution. Its shareholder is jointly liable unless he can prove separation — which is a creditor's friend, but only if you know the structure. (Supplier verification checks this before you pay.)
  4. Full payment before shipment is the riskiest structure there is. Tie the balance to loading, inspection, or the bill of lading.
  5. If a supplier offers an improper "fix" (adjusting meters, removing required parts), refuse in writing on the spot. Their admission becomes your strongest evidence.
  6. If the supplier won't show its business license, that is a red flag. Verify identity before signing, not after a dispute.
