CBAM Sector Brief · Cement
CBAM compliance for cement importers
Cement and clinker imports into the EU above 50 t/year require Authorised CBAM Declarant status. Carbon Border builds your NCA pack, collects kiln emissions, and procures CBAM certificates against your verified ledger every quarter.
Who needs CBAM authorisation for cement?
EU-established importers of clinker (CN 2523 10), Portland cement (CN 2523 21, 2523 29), aluminous cement (CN 2523 30), other hydraulic cements (CN 2523 90) and calcined kaolinic clays (CN 2507 00 80) whose total CBAM-scope imports exceed 50 t/year.
How embedded emissions are calculated
Cement is the most carbon-intensive bulk construction material. ~60% of emissions come from calcining limestone (process emissions), ~40% from kiln fuel combustion. CBAM captures both. Verified data is essential — many North African and Turkish kilns have alternative fuel substitution rates that reduce emissions 20-40% below the default.
In 2026, the EU default value carries a +10% markup when the importer cannot present verifier-signed supplier emissions. Verified data nearly always lowers your CBAM certificate liability — Carbon Border collects it for you via secure supplier portals.
Common HS / CN codes in this sector
Top origin countries currently subject to CBAM filings for this category include Türkiye, Egypt, Algeria, Belarus, Vietnam.
UK CBAM (from 2027)
Cement and clinker are in scope of UK CBAM from 1 January 2027. Carbon Border maintains a single emissions ledger covering both EU and UK declarations, reusing the same supplier verification and shipment data.
What Carbon Border does for cement importers
- Generates the full NCA Application Pack (Operational Capacity, Financial Exposure, HS-Code Alignment)
- Logs every shipment against the live ETS price and your verified emissions data
- Sends secure supplier portals so mills, smelters and producers upload signed emissions data
- Procures the right number of CBAM certificates each quarter via Stripe
- Maintains the 5-year audit trail required by Article 30 of Reg. (EU) 2023/956
- Mirrors the same workflow for the UK CBAM going live in 2027
Frequently asked questions
Why is cement included in CBAM at zero threshold for some HS codes?
All cement and clinker CN codes listed in Annex I count toward the same 50 t/year importer-level threshold. There is no per-CN-code zero threshold for cement (unlike hydrogen and electricity).
Does CBAM cover finished concrete or precast products?
No — currently only cement, clinker and calcined clays are in scope. The European Commission is reviewing whether to extend CBAM to downstream construction materials before 2030.
How do alternative fuels affect CBAM liability?
Verified use of biomass and waste-derived fuels at the kiln reduces embedded emissions. The supplier must produce a verifier-signed monitoring report showing the biomass fraction and the CO₂ benefit, which Carbon Border maps to your shipments.
What about CCS-equipped cement plants?
Verified CO₂ captured and permanently stored is deducted from embedded emissions, provided the storage meets EU CCS Directive requirements. The verifier statement must include the storage operator's MRV report.
Will the UK accept the same kiln emissions data?
Yes. UK CBAM uses an aligned methodology for cement embedded emissions. Carbon Border's verified supplier data flows into both the EU CBAM quarterly report and the UK HMRC return.
