This arrived in October from a buyer in Manchester: 240 charging boards from a Dongguan factory failed on arrival, the factory offered to repair them free of charge, and the buyer wanted a straight answer on whether shipping them back was worth it. It usually is — but the batch has to leave the destination as a repair return, not as an ordinary import. That distinction is not bureaucracy for its own sake. It decides whether duty and import VAT are paid a second time on goods that are about to leave China again.
Two procedures, and only one of them fits
Chinese customs treats goods coming back to be repaired differently from goods being returned unsold. Everything else in the file follows from which one you are actually doing.
| Returned goods (unsold, rejected) | Return for repair | |
|---|---|---|
| Purpose | the goods come back to stay, or to be sold again in China | the goods come back to be repaired, then leave again |
| Typical treatment | duty and import VAT relieved where the original export is proven and the deadline is met | relieved on entry against a guarantee; the repair itself is declared |
| Time window | generally within one year of the original export | shorter, commonly six months, extendable on application |
| What must leave again | nothing | the same units, repaired, under the same entry |
Both routes are decided by evidence, not by intent. If the paperwork shows an ordinary import, that is what it becomes, whatever the commercial story was.
What the file has to contain
Six items come up in every repair return we handle. Missing any one of them moves the shipment into a different, more expensive procedure.
- The original export declaration and the outbound bill of lading. This is the proof that the goods left China, and it is the item most often missing — factories lose it after a couple of years.
- A repair contract or the factory’s written undertaking, naming the units, the fault and the price of the work.
- Serial numbers or batch codes that match between the outbound and inbound lists. Customs reads these two lists side by side.
- A consignee in China that holds import rights — normally the factory or its trading company. An overseas buyer cannot act as consignee on its own, which is the first thing that stops a return from outside.
- A guarantee or deposit, cash or bank instrument, assessed against the entry. It is released when the repaired goods are re-exported.
- A licence check before booking: some categories need certification, and used goods are not welcome in every tariff line.
The clock is the risk, not the freight
On a repair return the freight is rarely the number that hurts. The guarantee is: money parked with customs for the length of the repair, plus the exposure if the goods do not leave in time. A factory waiting for a single component can burn three months without anyone noticing, and the file does not care that the delay was technical.
Practically, that means three things: get the repair quoted with a date before the goods move, keep a fortnight of slack against the re-export window, and agree in writing who applies for an extension if the part slips. On our own files we would rather see a repair plan that finishes in six weeks than a promise that it will be quick.
What the reverse leg costs
For a 40HQ from Northern Europe to Shenzhen in November 2026, the cost lines look like this. Treat the figures as structure rather than quotation — ocean rates move weekly and the guarantee depends on the assessed value, not on the freight.
| Cost line | What it covers | Notes |
|---|---|---|
| Ocean freight and origin handling | space, export clearance, loading | indicative low thousands of US dollars on this lane; a small share of the total |
| China import handling | entry, inspection, delivery to the factory | priced per entry, not per container |
| Guarantee | deposit or bank instrument, held for the repair period | the largest cash item; released on re-export |
| Return leg | repaired goods back to the buyer | often consolidated, not a second full container |
| Time | weeks out of the market | the line nobody puts in the spreadsheet |
Four things that actually go wrong
- No proof of export. The batch is assessed as a normal import, duty and VAT fall due, and the repair stops being the point of the shipment.
- Value added by the repair is not declared. Work done in China on goods that will be sold on has a customs value of its own; leaving it out is the sort of omission that surfaces a year later.
- The serial lists do not match. Customs queries the entry, the container sits, and storage accrues while two spreadsheets are reconciled.
- The window closes while the goods wait. The guarantee converts, and you pay duty on units you are about to ship out of the country.
When sending it back is the wrong answer
If the batch is worth less than the freight and the guarantee together, repair locally or sell it as is. If the fault is a single part that travels well, ship the part and not the goods. If the season is the constraint, the weeks at sea decide the outcome before the cost does. The arithmetic is unglamorous: value of the recovered goods, minus freight, minus handling, minus the cost of the money tied up in the guarantee, compared with what the batch is worth where it is.
Where we sit in this
Our desk in Shenzhen runs both directions — door-to-door into China and out of it — plus FBA first-leg bookings and Thailand DDP where the question is who acts as importer. Plastic pellets, chemicals and auto parts are the cargo we handle most on these lanes, which is also where the licence and packing questions above tend to appear. We will not tell you that a repair return is cheap. We will tell you what the file needs, and what the guarantee will tie up while it runs. Send the outbound declaration, the fault description and the destination city, and we will come back with a costed route and the document list.
