China’s exports of fabricated metal products and machinery components could face greater carbon-related scrutiny under the European Union’s proposed expansion of the Carbon Border Adjustment Mechanism (CBAM). The initiative would extend the mechanism beyond basic steel and aluminium, bringing emissions accounting further into industrial supply chains connecting Chinese manufacturers with European customers.
The European Commission proposed adding 180 steel- and aluminium-intensive downstream products to CBAM from 2028. In September 2026, the European Parliament backed a broader scope, while the Council adopted its own negotiating position in June. These remain institutional positions rather than a final regulation. The eventual commercial impact will depend on which customs classifications are included in the final legislation and how emissions from precursor materials are attributed.
Carbon accounting moves further down the supply chain
China supplies European industry at multiple stages of the metal value chain. Its exports include steel and aluminium inputs as well as finished fasteners, metal mountings, components and industrial equipment. Under the existing framework, certain upstream materials are covered by CBAM while some finished products remain outside its scope.
If the proposed expansion is adopted, European buyers could increasingly assess suppliers according to the carbon-adjusted delivered cost of their products rather than invoice prices alone. The treatment of embedded emissions could become an additional consideration in sourcing decisions, alongside quality, reliability and conventional production costs.
For Chinese fabricators, the origin and production history of the metal used in a component could be particularly important. A part manufactured from purchased steel may have a different emissions profile from an otherwise comparable item made using material from another steel mill.
Production records, bills of materials, purchase contracts and precursor-emissions calculations could therefore become increasingly important for demonstrating compliance with any future requirements. Evidence of renewable electricity use or low emissions at the final fabrication facility would not, by itself, replace upstream documentation required under the eventual rules.
Steel export growth provides a separate trade indicator
The proposed downstream changes come as Chinese finished-steel shipments to the EU are increasing. EUROFER recorded a 40% rise in Chinese shipments in the first half of 2026, bringing China’s share to 12.3% of EU finished-steel import volume.
These figures describe current finished-steel trade and should not be interpreted as a measure of Chinese machinery or fabricated-product exposure under the proposed downstream legislation. Although the markets are commercially connected through shared supply chains, the available figures relate to different product groups.
The distinction is important as importers assess potential regulatory costs. Growth in covered steel shipments does not establish how much trade in downstream manufactured goods would ultimately fall within an expanded CBAM, since that would depend on the customs codes and products included in the final legislation.
Separate trade measures complicate planning
The EU has also applied tighter steel import quotas and a 50% out-of-quota duty on relevant steel products since July 2026. These measures operate separately from the proposed downstream CBAM expansion and should be assessed under their respective rules.
Chinese exporters and their European customers will need to distinguish between commodity steel shipments already subject to applicable trade measures and manufactured products that may enter an expanded CBAM scope from 2028 or later. The timing and final coverage of the latter remain subject to negotiations.
Traceability could influence supplier competitiveness
The ability to provide reliable emissions evidence could become a differentiating factor among Chinese exporters. Producers with traceable inputs and dependable installation-level data may be better positioned to substantiate lower embedded emissions where the rules permit such reporting. Exporters unable to obtain precursor records could face less favourable assumptions where applicable, consider alternative materials or absorb part of the additional cost to maintain their position in the European market.
The potential impact would extend beyond the administrative task of reporting emissions. Differences in documentation, contractual arrangements and the treatment of embedded carbon could affect the net margins of otherwise comparable products.
The proposed expansion does not necessarily imply a halt to European imports of Chinese manufactured goods. Rather, it could change how suppliers compete for business as carbon-related costs become more closely linked to the materials used and the evidence available to support emissions calculations.
For China’s industrial exporters, traceability and access to upstream production data could become increasingly important alongside manufacturing scale, product quality and price. The extent of that shift will depend on the final EU legislation and the rules governing its implementation.
