Does a UK buyer importing under £50,000 of United Kingdom (UK) Carbon Border Adjustment Mechanism (CBAM) goods still have to keep records?

Probably yes. HM Revenue and Customs (HMRC) says anyone importing CBAM goods into the UK will need to keep records of them from 1 January 2027. Our reading: a buyer under £50,000 still needs the records to show it stayed under.

What HMRC says

• Records page: "Anyone importing CBAM goods into the UK will need to keep records of the CBAM goods they have imported from 1 January 2027."
• Policy summary: "Anyone importing CBAM goods into the UK will be required to keep under review whether they need to register with HMRC and account for CBAM."
• Records are kept in written or electronic form for 6 years. HMRC says "You may be charged a fixed penalty of £500" if records are not kept.

Why a small buyer needs them

To keep the registration question under review, a buyer must know what it imported. It checks the past 12 months and, on any day, the next 30 days. That needs the value and the date of each CBAM shipment.

It is like keeping till receipts to prove you did not sell enough to need a licence. Without them, "we were under the limit" is only a claim.

What each record holds

• The 8-digit commodity code and description of each good.
• The date it passed the tax point.
• Its value and its weight.
• Evidence for any exemption from CBAM.

What the pages do not say

We found no line on HMRC's records page that excuses a buyer below the limit from keeping records. That page opens with "Anyone importing". HMRC's policy summary also says anyone who is liable for CBAM must keep records of the CBAM goods they import, so the records page is not limited to those who are liable. This is our reading of the wording, and HMRC may publish more detail, so a buyer that wants certainty can ask HMRC.

What this means for an Indian supplier

• Put the 8-digit code, net weight and value on every invoice, even for small orders.
• A small buyer may ask you for these figures later. Having them ready saves a scramble.
• Do not read a small order as a reason to skip paperwork.

A buyer that stays under the limit

• Shipment 1: £12,000
• Shipment 2: £9,500
• Shipment 3: £14,000
• Total over the period: 12,000 + 9,500 + 14,000 = £35,500, which is under £50,000
• To show that, the buyer needs the value and date of all three shipments.

Values are an example, not a real buyer.

What Senseible does here

Senseible reads fuel invoices and electricity bills into dated, fingerprinted records. It does not file UK CBAM returns, work out your buyer's registration date or check commodity codes. Those stay with the importer and HMRC.

• How the £50,000 value is counted
• What records a UK buyer asks you for
• UK CBAM for Indian exporters
