1. The Financial Impact of the CBAM Definitive Phase
The end of the transitional period means that importers must now purchase CBAM certificates to cover the verified greenhouse gas emissions of their goods. The cost of these certificates is tied directly to the EU Emissions Trading System (ETS).
In late 2025, the EU carbon price stabilized at approximately €85.17/tonne, with an annual average reaching €90/tonne. In stark contrast, China’s national carbon price remains significantly lower, at roughly €8.5/tonne (CNY 62). This creates a massive carbon price gap of over €81/tonne, which will serve as a direct cost increase for products exported from China to the EU.
2. Why Polyurethane Precursors (MDI, TDI, Polyols) are at Risk
While the initial CBAM rollout focused on basic materials like steel and cement, the chemical sector is now the primary target for expansion. The European Commission has identified 180 downstream products and over 120 chemicals and polymers for potential inclusion.
-
High Carbon Intensity: Key polyurethane precursors such as MDI (Methylene Diphenyl Diisocyanate), TDI (Toluene Diisocyanate), and polyether polyols are under scrutiny due to their high production-related emissions.
-
Cost Projection: Producing one tonne of polyurethane foam generates approximately 2.3 tonnes of CO2 equivalent. Under the definitive phase, this could result in an additional CBAM cost of €195.5/tonne, accounting for roughly 7.2% of the FOB (Free On Board) price.
-
Downstream Scope: Exported appliances and machinery containing PU insulation are already facing stricter reporting requirements, signaling that the entire PU value chain is effectively within the mechanism's reach.
3. Short-Term Challenges: Cost and Compliance Pressures
The full enforcement of CBAM introduces immediate hurdles for Chinese manufacturers, particularly those reliant on traditional, high-emission production methods.
-
Significant Margin Compression: Affected products could incur €80-120/tonne in additional compliance costs, representing 5-8% of total product value.
-
Complex Carbon Accounting: Enterprises must now establish rigorous systems for measuring lifecycle emissions. This includes securing Environmental Product Declarations (EPDs) that meet stringent EU verification standards.
-
The SME Gap: Small and medium-sized enterprises (SMEs) may face severe competitive disadvantages due to the high technical and capital requirements for carbon compliance and production upgrades.
4. Long-Term Opportunities: A Catalyst for Green Innovation
Despite the costs, CBAM serves as a powerful driver for the technological upgrading of China's polyurethane industry, rewarding firms that lead in sustainability.
-
Market Consolidation: The mechanism is likely to accelerate industrial consolidation, favoring large-scale players with the resources to invest in green transition technologies.
-
R&D Breakthroughs: CBAM creates a clear market advantage for bio-based polyurethanes, low-GWP (Global Warming Potential) blowing agents, and advanced chemical recycling solutions.
-
Strategic Advantage through Certification: Companies that already comply with REACH and RoHS standards are better positioned to integrate carbon management, increasing their product value and differentiation in the global market.
5. Strategic Roadmap for Chinese Polyurethane Firms
To navigate this evolving landscape, Chinese PU producers should adopt proactive measures to mitigate trade risks and capture new market shares:
-
Establish Robust Carbon Management: Implement comprehensive carbon tracking systems and obtain international green certifications early to ensure uninterrupted market access.
-
Invest in Low-Carbon Technology: Focus on R&D for circular economy solutions and energy-efficient production processes to lower the "embedded carbon" of exported goods.
-
Supply Chain & Market Diversification: Optimize supply chains to reduce dependence on high-carbon raw materials and explore emerging markets with different regulatory profiles to reduce over-reliance on the EU.
-
Pivot to Integrated Solutions: Transition from being a simple product manufacturer to an integrated green solution provider, adding value through sustainability consulting and carbon-neutral product lines.
Conclusion
The definitive phase of CBAM marks the beginning of a new era where green and low-carbon capabilities are the core competitive differentiators. For Chinese PU producers, this is a pivotal moment to embrace innovation and transform the "CBAM challenge" into a strategic opportunity for global leadership in sustainable chemistry.
