The EU carbon border’s 50-tonne threshold changes which buyers matter

An Indian supplier preparing for the European Union’s carbon border mechanism should start by finding out how its buyer imports. The October simplification law introduced a 50-tonne threshold for annual covered imports per importer across iron and steel, aluminium, fertilisers and cement. It exempts an importer whose cumulative net mass in those sectors does not exceed that threshold, subject to the regulation. A small order from India can still enter the scope through a buyer importing larger quantities elsewhere. This makes the buyer’s portfolio a more useful starting point than the size of any one export consignment. EU Regulation 2025/2083 on CBAM simplification · EU Regulation 2023/956 establishing CBAM

The threshold applies to a year and an importer

Article 2a distinguishes the volume accumulated in a relevant calendar year from the size of an individual shipment. If an importer exceeds the threshold, obligations apply to the covered goods it imported during the year, rather than only to the excess volume. The mass exemption does not cover electricity or hydrogen. Classification and the identity of the importer remain material. An exporter negotiating a contract should understand which counterparty will carry the obligations and what evidence that counterparty needs in order to price and administer them.

Suppose an EU buyer expects 30 tonnes of covered steel from one supplier and 25 tonnes of covered aluminium from another. The assumed total is 55 tonnes, even though neither order by itself reaches 50. With the law’s scope and eligibility conditions satisfied, the annual total crosses the threshold. Now consider a buyer importing only 45 tonnes of covered goods in total, including 30 from the same steel supplier. The exemption can apply to that importer. This example isolates the threshold and assumes ordinary imports of covered products. It shows why suppliers of similar volumes can face different requests for emissions information.

A lower reporting burden can still change sourcing

The regulation’s policy rationale is to remove a large number of small importers from compliance while covering the great majority of emissions. That can reduce fixed costs for firms using small amounts of specialised material. It may also change the bargaining position of buyers near the threshold. A buyer uncertain whether demand will expand may want documentation even on early orders. If it crosses the threshold later, it needs to know the emissions associated with the imports already made. Suppliers able to produce credible information on time can have an advantage independent of whether their own shipment is large. EU Regulation 2025/2083 on CBAM simplification

These compliance costs do not necessarily fall entirely on the company with the legal duty. A buyer can negotiate a lower product price, require the supplier to fund records and verification, or choose another source that can provide them. An exporter with a distinctive product and few rivals may retain more bargaining power than a seller of a commodity with many substitutes. The distribution of costs across firms depends on the elasticity of demand and on how easily the buyer can switch. The exporter should compare its net margin after documentation and negotiation costs, alongside the buyer’s eventual certificate bill.

Plan for a volume range before agreeing a fixed price

A buyer that imports about 45 tonnes in a normal year may exceed 50 after winning another order. If the parties agree a fixed delivered price without settling who will supply documentation or absorb unforeseen costs, the threshold can become a commercial dispute. An illustrative business that expects €2,000 in fixed administrative costs if it enters scope would allocate about €36 per tonne over 55 tonnes, before any certificate cost. This is a hypothetical compliance cost. It illustrates how the fixed part can be large for small volumes and how it differs from the charge associated with emissions.

The strongest counterargument is that the threshold makes the new regime less relevant to many smaller traders and therefore reduces the need for early investment in records. That is plausible for a supplier with customers that can confidently remain below the limit and whose product data are costly to establish. A phased response would gather the core production data needed for several buyers and reserve more expensive verification for orders where the commercial case is clear. Where buyers may cross the threshold or where the same data can support several contracts, delaying collection until year-end can be costly.

A simplification intended to remove small importers can also change how firms organise purchasing. A distributor may serve several customers and therefore reach the annual limit sooner than any one of them would through direct imports. That does not imply direct purchasing is cheaper. A distributor can spread fixed compliance costs, assemble orders and maintain better records. The net cost depends on how much those services are worth compared with the obligations triggered by the distributor’s aggregate imports. The policy is more likely to improve market access where buyers can make that comparison before placing orders. EU Regulation 2025/2083 on CBAM simplification

The practical baseline should be the covered net mass the importer expects across its entire purchasing programme, including already committed orders. That forecast can be updated as contracts are signed. A supplier can provide a margin range for sales with and without additional documentation costs. This separates normal uncertainty about future sales from uncertainty about whether the same paperwork can be supplied in time.

The evidence to collect during the first year

Follow requests for data, volumes by buyer and product, the time needed to produce verified figures and the prices suppliers actually receive. Compare whether buyers close to the threshold seek different terms from similar buyers farther away. If smaller importers face a genuinely lighter burden while firms in scope can comply at reasonable cost, the simplification will have improved the design. If volume uncertainty leaves many suppliers negotiating over missing records after the fact, the commercial response should be earlier disclosure and clearer contracts. The threshold is useful only when firms understand whose volume it measures and when that volume can change. EU Regulation 2025/2083 on CBAM simplification
