Do goods that return to the UK carry the UK Carbon Border Adjustment Mechanism (CBAM)?
Not if returned goods relief is available. HM Revenue and Customs (HMRC) says goods reimported unaltered within 3 years of export carry no CBAM liability, need not go on the return, and do not count towards the £50,000 threshold. The importer does not have to be the person who exported them.
What HMRC says
- Where returned goods relief is available for a CBAM good imported into the UK, "there will be no CBAM liability".
- The same applies to Union goods exported from Northern Ireland into the European Union and reimported into the UK, if reimported within 3 years of export and returned in the same state.
- Where all conditions are met, the returning good "will not need to be declared on a CBAM return or be factored into the calculation for the £50,000 minimum registration threshold".
- "The person importing the CBAM good does not need to be the same person that exported the good to claim this relief for CBAM."
Evidence the importer keeps
- Proof of the earlier UK export.
- Proof of reimport into the UK within 3 years.
- Evidence the goods are in the same state.
- Import declarations for the reimport.
- Serial or batch numbers or packing lists.
A limit to keep in mind
HMRC's wording is about reimport of unaltered goods. Goods processed abroad and returned fall under different rules, covered in the linked page. Our reading: a reshipment from India of goods that were first made in India is not a UK export coming back, so this relief would not apply to it.
What Senseible does here
Senseible reads fuel invoices and electricity bills into dated records, which feed a plant's emissions figure. It does not claim customs reliefs or hold export proofs.
