Non‑EU suppliers are discovering that CBAM is not a regulation that only affects European companies. Although the legal obligations sit with the importer, the effects reach upstream into foreign supply chains and demand emissions data from facilities that may never have measured their carbon footprint before. Because the authorised CBAM declarant is legally responsible for CBAM reporting, suppliers outside the EU now face pressure to provide accurate, verifiable emissions data. If they cannot, they risk losing their EU customers.
Understanding how CBAM works from a non‑EU perspective is essential for exporters, manufacturers, distributors and any business that supplies goods into the EU, whether directly or through UK, Irish, or other intermediaries. CBAM affects pricing, documentation, production processes and long‑term competitiveness.
Why CBAM Applies to Non‑EU Businesses
CBAM exists to prevent carbon leakage. Carbon leakage happens when companies move production to countries with weaker climate policies in order to avoid carbon costs. The EU wants to ensure that domestic manufacturers who pay for carbon under the EU ETS are not undercut by cheaper imports produced with higher emissions.
Legally, CBAM applies to the importer, not the exporter. The obligations fall on the authorised CBAM declarant that brings covered goods into the EU, which could be an EU‑established importer or an indirect customs representative acting on its behalf. Suppliers are pulled in because the declarant needs their emissions data to meet those obligations. This means a steel mill in Turkey, an aluminium smelter in India, a fertiliser plant in Egypt or a hydrogen producer in the Gulf will all feel the effects of CBAM if their products are sold into the EU market.
Not every importer is affected, however. A de minimis threshold of 50 tonnes per year excludes many smaller importers. So, those bringing in no more than 50 tonnes net mass of CBAM goods in a calendar year are exempt from CBAM obligations. The threshold is assessed across all covered goods combined, and once exceeded, CBAM applies to all imports for that year. However, the threshold does not apply to electricity or hydrogen, which are covered regardless of volume.
Non‑EU suppliers must understand what emissions data the EU requires, how those emissions must be calculated, what verification evidence is acceptable, how importers will use the data and how CBAM certificate pricing will affect competitiveness. Many exporters already struggle to collect the right emissions data because CBAM demands a level of detail far beyond typical sustainability reporting.
The Goods Covered Under CBAM
CBAM currently applies to iron and steel, aluminium, cement, fertilisers, electricity and hydrogen. These sectors were chosen because they represent some of the highest embedded emissions in global trade. CBAM is expected to expand in 2028 to include additional downstream products with a high steel or aluminium content. The proposal is still going through the EU legislative process, so the final product list has not yet been confirmed. Further sectors and indirect emissions may be considered in later reviews.
This expansion matters for non‑EU businesses because many supply chains include mixed products or components that fall into CBAM‑covered categories without being obvious at first glance. A manufacturer exporting finished goods may rely on upstream suppliers whose inputs appear similar to CBAM‑covered materials, but the imported product’s CN code alone determines whether it is within CBAM scope, not the presence of steel or other covered inputs.
If the expansion goes ahead, some finished and semi‑finished goods that are outside scope today will be brought in. Suppliers already struggling to calculate their CBAM emissions should expect the complexity to increase as the mechanism evolves.
How CBAM Reporting Works From a Non‑EU Perspective
Although authorised CBAM declarants are legally responsible for submitting CBAM reports, non‑EU suppliers play a critical role. Declarants cannot report actual emissions without supplier emissions data. The only alternative is to rely on applicable default values published by the EU.
Non‑EU suppliers must provide total embedded emissions for each product, direct emissions and, in some circumstances, indirect emissions from the electricity used in production, evidence of any carbon price paid in the country of origin, identification details of the production facility and verification documents that meet EU standards.
If the supplier’s data is incomplete or unverifiable, the importer may be forced to use default values. Default values include a mark‑up, so they can make the supplier’s goods significantly more expensive once certificates have to be paid for. This is why many non‑EU businesses are now investing in emissions measurement systems, verification processes and internal reporting frameworks. Without them, they risk losing EU customers who cannot absorb the higher carbon cost attached to default values.
The Transitional Phase
The transitional phase ran from 1 October 2023 until 31 December 2025. During this period, importers had to submit quarterly CBAM reports but did not yet need to purchase certificates. This gave non‑EU suppliers time to build emissions measurement capability, train staff on CBAM requirements, establish data collection processes and prepare for verification.
Many suppliers underestimated the complexity until they saw the reporting templates. They realised that emissions data must be calculated using specific methodologies rather than generic sustainability metrics. This is why importers often struggled when preparing their first CBAM report because suppliers were not ready.
Verification Requirements for Non‑EU Businesses
Since 1 January 2026, the definitive CBAM regime has applied. Where actual emissions are declared, they must be verified by an accredited verifier before they are used in the annual CBAM declaration. The first declaration, covering goods imported during 2026, is due by 30 September 2027.
The EU has strict rules about what counts as acceptable evidence. Non‑EU suppliers must ensure their verification processes align with EU expectations rather than domestic standards. Verification bodies in their home country may not be accredited for CBAM, may not follow EU‑aligned methodologies or may not provide the level of detail CBAM requires.
Understanding what counts as acceptable verification is essential for any supplier that wants to remain competitive in the EU market.
How CBAM Affects Pricing for Non‑EU Businesses
Under the definitive CBAM regime, which began on 1 January 2026, authorised CBAM declarants must purchase CBAM certificates based on the embedded emissions of the goods they import. The cost is already building up on 2026 imports, but it is paid from 2027. CBAM certificates go on sale on 1 February 2027, and the first annual declaration and certificate surrender for 2026 imports is due by 30 September 2027. From 2027 onwards, declarants must also hold enough certificates at the end of each quarter to cover at least 50% of the embedded emissions of their imports so far that year.
Higher emissions mean more certificates and therefore higher cost. The number of certificates required is adjusted to reflect the free allowances EU producers still receive under the EU ETS, which are being phased out gradually, so the effective charge starts low and rises each year. Suppliers with lower emissions will become more competitive as that charge grows.
CBAM creates a direct financial incentive for non‑EU businesses to reduce emissions or improve measurement accuracy. Many suppliers are already exploring the mechanics of CBAM certificate purchasing and surrendering (CBAM Certificates: Pricing, Purchasing and Surrendering) to anticipate how their pricing will need to evolve.
The Role of UK and Irish Businesses
Many non‑EU suppliers sell into the EU through UK or Irish businesses, but CBAM treats the two very differently. An importer established in the Republic of Ireland can apply to become an authorised CBAM declarant in its own right. A UK business cannot. To import CBAM goods into the EU, a UK business needs either an EU establishment or an indirect customs representative with authorised CBAM declarant status that takes on the CBAM obligations on its behalf. Allied Group can act as that indirect customs representative for UK businesses.
Although Northern Ireland follows certain EU rules for goods under the Windsor Framework, EU CBAM does not apply there. Instead, Northern Ireland sits under UK CBAM, which applies to goods imported into the UK from 1 January 2027. Businesses across Great Britain and Northern Ireland therefore need to prepare for UK CBAM on the goods they import, while also supporting their EU customers with emissions data for EU CBAM on the goods they export.
UK businesses exporting to the EU are non‑EU suppliers in their own right. The UK and EU are negotiating a link between their emissions trading systems, which is intended to create mutual exemptions from each other’s CBAMs. Until an agreement is in force, UK‑origin goods are treated like any other imports under EU CBAM. Any carbon price already paid in the UK, such as under the UK ETS, can be deducted, but only if the supplier can evidence it.
Why Supplier Data Is a Commercial Issue
Whatever the route into the EU, the responsibility is shared. Suppliers must provide accurate emissions data, and importers must report it correctly. Many suppliers assume that because the importer is responsible for reporting, the supplier’s role is minimal. This misconception is one of the common CBAM myths that continues to cause reporting delays and errors.
For suppliers outside the EU, the biggest risk is not a formal penalty. The real danger is becoming too expensive for EU buyers to work with. When emissions data is missing or unreliable, importers have no choice but to use the EU’s default values. These values are intentionally high. Once they are applied, the goods appear far more carbon‑intensive than they actually are. The certificate cost rises, and EU customers begin looking for alternative suppliers. This is already happening in sectors like steel and fertilisers where buyers increasingly compare suppliers based on the carbon cost attached to each shipment.
Pressure increases under the definitive CBAM phase, which has been in effect since 1 January 2026. Importers need defensible emissions figures and documentation that aligns with EU rules. When suppliers cannot provide that, the relationship becomes strained. Buyers start questioning whether the supplier can meet CBAM expectations. Some quietly shift orders to producers with their reporting in order. This is why understanding the consequences outlined in CBAM penalties and enforcement matters for suppliers as much as it does for importers.
How Non-EU Suppliers Are Preparing for CBAM
Preparing for CBAM is not something non‑EU businesses can leave until the last minute. The companies that adapt quickest are treating CBAM as part of their commercial strategy rather than a compliance chore. They are putting proper emissions measurement in place, training staff to understand what the EU expects and building internal processes that make data collection routine rather than a scramble. Others are working with verification bodies early so their 2026 data is verified in time for the first annual declaration in September 2027.
For many suppliers, the biggest shift is cultural. CBAM forces them to look at their production processes through a carbon lens, often for the first time. It means keeping better records, understanding how emissions are calculated and being able to explain those numbers to EU buyers who now depend on them for their own reporting. Some suppliers are turning to digital tools to make this easier, especially as importers begin asking for structured data formats that align with CBAM templates. This trend is pushing more businesses to explore CBAM software and tools that can handle the complexity.
