Timeline for CBAM Implementation: Critical Dates for Indian Businesses

Key Takeaways

• Now (2025): Transition period; Mandatory quarterly reporting; Actual data required.
• Dec 31, 2025: End of Transition Period.
• Jan 1, 2026: Financial liability begins (CBAM Certificate purchase).
• 2034: Full phase-in (100% of free allowances removed).

Introduction

The Carbon Border Adjustment Mechanism isn't a single event; it's a decade-long ramp-up. For Indian strategy teams, knowing the timeline is crucial for CAPEX planning (e.g., when to invest in green hydrogen or electric furnaces).

Phase 1: The Transition Period (Oct 1, 2023 – Dec 31, 2025)

• Status: Active.
• Requirement: Reporting Only. No Payments.
• Critical Shift (July 2024): Ban on unrestrained use of "Default Values". Exporters must now measure actual data.
• Goal: EU collects data to refine the definitive system. Indian exporters refine their monitoring systems.

Phase 2: The Definitive Period Starts (Jan 1, 2026)

• The "Cash" Phase: Importers must buy "CBAM Certificates" (priced similarly to EU ETS allowances).
• Coverage: Initially covers Cement, Iron & Steel, Aluminum, Fertilizers, Electricity, Hydrogen.
• Free Allowances: EU domestic industries still get some free carbon allowances. CBAM only charges for the difference.
  • 2026: CBAM applies to 2.5% of emissions.
  • 2027: 5%.
  • 2028: 10%.
  • ... ramping up rapidly after 2030.

Phase 3: Full Implementation (2030 – 2034)

• 2030: A major step-up. Review of inclusion of other sectors (Polymers, Chemicals, Glass?) likely completes.
• 2034: 100% CBAM liability. No free allowances for EU producers, meaning 100% tax on embedded emissions for Indian exports.

2025-2026 Regulatory Impact for India

• The "cliff edge": Many Indian contracts are long-term (3-5 years). A contract signing today (2025) extends into the 2027-2028 liability period.
• Action: Include "CBAM Clause" in contracts now. Define who pays the tax? Usually, the importer pays the tax but deducts it from the supplier's price.
