Customs Clearance for Repairs and Warranty Returns
Goods moving for repair or warranty work are not ordinary sales, but they still require a value, a clear ownership trail and the correct customs procedure. Cartwright CS helps businesses plan the outward and return movements so duty and VAT are handled correctly and the customs procedure is properly closed.
We are Cartwright Customs Services
Cartwright CS Ltd is a UK customs broker and customs agent based in Southampton, Hampshire. We support businesses, freight forwarders, removal companies, hauliers and private clients with customs declarations, border documents and practical coordination across the UK and Europe.
Our approach is simple: gather the right information early, explain what is needed in plain English and keep the customs paperwork connected to the real movement of the goods.

- Imports into the UK for repair under inward processing where eligible
- Temporary exports for repair under outward processing
- Warranty replacements and no-charge movements
- Return-to-vendor and rejected-goods exports
- Re-import and re-export declaration matching
- Repair charges, transport costs and valuation review
- Serial-number and identity evidence

- Technology and engineering businesses
- Marine and automotive repairers
- Retailers handling warranty claims
- Freight forwarders managing return logistics
- Businesses returning faulty stock to overseas suppliers


Why this service matters
A zero-value invoice does not mean the goods have no customs value. The original export or import, repair cost, ownership and reason for return all influence the declaration. If the first movement is declared incorrectly, relief on the return can be harder to support.
How Cartwright CS helps
We connect the original movement to the repair and return. We identify the appropriate procedure, specify what must appear on the invoice and packing list, and retain the MRNs and serial-number evidence needed for discharge or relief.


Common challenges we solve
- The invoice says 'no commercial value' with no customs value
- The original export or import MRN cannot be found
- Replacement goods have a different serial number
- The repair is free under warranty but transport costs remain
- Goods are returned after the procedure deadline
- Ownership changes during the repair
- The business has no inward or outward processing authorisation
How the process works
- Confirm whether the goods are leaving or entering for repair and who owns them.
- Provide original declarations, invoices, serial numbers and warranty evidence.
- We determine whether normal import, RGR, inward or outward processing may apply.
- The first movement is declared with the return in mind.
- Repair or replacement evidence is retained.
- The return declaration is matched and any procedure is discharged.


Why choose Cartwright CS
Repairs and warranty movements need a clear link between the goods leaving, the work performed and the goods returning. We review identifiers, invoices and movement history before considering the appropriate customs procedure.
Where eligible, this may involve Inward Processing, Outward Processing or Returned Goods Relief. We focus on retaining the evidence needed for the later movement so a repair return is not treated as an ordinary sale by default.
Location and coverage
We are based in Southampton, close to Southampton and Portsmouth, and support customs movements across the UK. Depending on the service and route, we can assist through Southampton, Portsmouth, Dover, Felixstowe, Tilbury, London Gateway, Liverpool, Grangemouth, Immingham, Harwich and other UK locations, as well as coordinated European movements.

Frequently asked questions
Can I put a zero value on warranty goods?
A customs value is still required. The commercial invoice can explain that there is no sale while giving a realistic value for customs purposes.
Do free repairs always avoid duty and VAT?
No. The procedure, original status and evidence determine the treatment.
What if the replacement has a different serial number?
The warranty and replacement evidence should link the returned item to the replacement clearly.
Can you help obtain an inward processing authorisation?
Yes. We can advise on the options, application information, records and discharge responsibilities.
Sending goods for repair or receiving a warranty return?
Contact Cartwright CS before the first movement so the outward and return declarations work together.
