2026 Chemical Regulatory Outlook: Key Markets at a Glance

For companies supplying chemicals to international markets, 2026 is not a single-regulation compliance year. Instead, it is a year of overlapping deadlines across EU REACH, EU CLP, UK REACH, Turkey KKDIK, Ukraine REACH, U.S. OSHA HCS, and Latin American chemical inventory and notification systems.

EU REACH Microplastic Emissions Reporting Obligations Begin in 2026

Under the EU REACH regulation, specific uses exempted from the microplastic restriction are subject to annual reporting obligations. The first reporting milestone in 2026 applies to manufacturers and industrial downstream users of synthetic polymer microparticles (SPMs) in the form of pellets, flakes, and powders used as feedstock in plastic manufacturing at industrial sites.

These companies were required to report their 2025 emissions to the environment to ECHA by May 31, 2026. As this deadline has now passed, companies that were in scope should verify whether the report was submitted, whether submitted data are traceable, and whether internal processes are ready for subsequent annual reporting cycles.

In addition, in vitro diagnostic (IVD) devices containing SPMs and meeting exemption conditions must, by October 17, 2026, provide detailed instructions for use and disposal to help professionals and consumers prevent microplastic release into the environment. Companies may also need to update SDSs, labels and packaging information.

REACH24H recommendation: 2026 marks a key transition year for microplastic compliance, moving from sales restrictions to administrative supervision. Enterprises should verify reporting status, retain emissions calculation evidence, and build a repeatable annual data collection process for future submissions.

EU Revises CLP Regulation Annex I

On March 31, 2023, the EU formally published Commission Delegated Regulation (EU) 2023/707, amending Annex I of the CLP Regulation. The revision introduced new hazard classes for Endocrine Disruptors (EDCs) and Persistent, Mobile and Toxic/Very Persistent, Very Mobile substances (PMT/vPvM).

The amendment entered into force on April 20, 2023, with transition periods for substances and mixtures. For chemical substances newly placed on the market, updated classification, labels and SDS requirements started from May 1, 2025. For substances already on the market, the transition period extends to November 1, 2026. For mixtures newly placed on the market, the new rules apply from May 1, 2026, while mixtures already on the market have until May 1, 2028.

Product TypeKey DeadlineCompliance Action
New substancesMay 1, 2025Apply new hazard classes and update labels and SDSs.
Existing substancesNovember 1, 2026Complete reclassification, SDS updates and label transition.
New mixturesMay 1, 2026Classify mixtures under the revised CLP criteria before placing them on the market.
Existing mixturesMay 1, 2028Plan inventory transition and documentation updates.

REACH24H recommendation: Enterprises should plan classification, labeling, and SDS updates according to product type and market timeline. Companies with multiple EU product lines should prioritize existing substances facing the November 1, 2026 transition deadline.

UK REACH Transitional Registration Deadlines Extended to 2029–2031

Under the original UK REACH schedule, transitional registration deadlines for high-tonnage and high-hazard substances were set for October 27, 2026. Following public consultation, the UK government decided to postpone the three transitional registration deadlines originally scheduled for 2026, 2028, and 2030 to 2029, 2030, and 2031, respectively.

Substance CategoryNew DeadlineOriginal Deadline
High-hazard and high-tonnage substancesOctober 27, 2029October 27, 2026
Second tonnage / concern groupOctober 27, 2030October 27, 2028
Other substances above 1 tonne/yearOctober 27, 2031October 27, 2030

Regulatory amendments are expected to be finalized alongside the development of legislative details for the Alternative Transitional Registration model (ATRm). Companies must continue to maintain transitional compliance, including Downstream User Import Notification (DUIN), supply chain communication and SDS obligations.

REACH24H recommendation: The deadline extension may ease short-term registration pressure, but companies should not suspend UK REACH planning. High-tonnage and high-concern substances should remain priority targets for data gap analysis and registration strategy.

Turkey Sets 2026 Deadlines for KKDIK Registration and Interim Registration

Under Turkey’s KKDIK regulation, the first registration deadline for substances with production or import volume of 1,000 tpa or above is December 31, 2026.

Turkey’s Ministry of Environment, Urbanisation and Climate Change has also introduced an interim registration mechanism. Lead Registrants unable to file a complete dossier and companies filing individual submissions must complete interim registration by March 31, 2026. SIEF members must complete the joint submission of interim registration by September 30, 2026.

REACH24H recommendation: 2026 is critical for companies managing compliance in the Turkish market. Enterprises should closely monitor Lead Registrant progress within the SIEF and confirm whether full registration or interim registration is the appropriate route to maintain trade continuity.

Ukraine REACH Pre-Registration Deadline Extended to January 2027

Ukraine has officially confirmed the extension of the pre-registration deadline under UA REACH from January 26, 2026 to January 26, 2027. This makes 2026 a key preparation window for companies intending to enter or already operating in the Ukrainian market.

Although the pre-registration deadline has been postponed, companies should use the additional time to verify substance identity, volume bands, supply chain roles, data availability, representative arrangements and downstream communication needs. Early preparation may reduce the risk of administrative delays during the later registration phase.

REACH24H recommendation: Companies should not wait until 2027 to begin pre-registration preparation. Completing substance inventory review and supply chain alignment in 2026 can help secure a buffer for subsequent UA REACH registration.

U.S. OSHA HCS Revision: 2026 Marks Key Compliance Year for Substances Newly Placed on the Market

The U.S. Occupational Safety and Health Administration (OSHA) published the final rule amending the Hazard Communication Standard (HCS) on May 20, 2024, and the rule took effect on July 19, 2024. The revision aligns primarily with GHS Revision 7 while incorporating selected updates from GHS Revision 8, including new aerosol classification criteria.

For chemical substances newly placed on the U.S. market, companies must update SDSs and labels by May 19, 2026. For mixtures newly placed on the market, the compliance deadline is November 19, 2027. Companies should align U.S. product launch plans with classification assessment and documentation updates.

REACH24H recommendation: Companies should proactively review U.S. SDSs, labels, aerosol classification, small container labeling, trade secret claims and downstream communication to ensure timely HCS compliance.

Colombia to Launch Industrial Chemicals Prioritization Criteria in 2026

Colombia is expected to release prioritization criteria for industrial chemicals in 2026, clarifying detailed requirements for new substance notification. Under the current framework, hazardous substances not included in Colombia’s National Industrial Chemicals Inventory (INSQUI) and used for industrial purposes must be notified within six months after annual production or import reaches 100 kg.

New substances falling within the prioritization scope may require a comprehensive health and environmental risk assessment report. Companies supplying chemicals to Colombia should monitor the release of the prioritization criteria, verify inventory status, track annual volumes and prepare toxicological and environmental data in advance.

REACH24H recommendation: Enterprises should closely monitor Colombia’s regulatory updates, particularly for non-listed hazardous substances with annual trade volumes exceeding 100 kg. Early ingredient traceability and data preparation can help reduce risks of notification delays and market-entry disruption.

Compliance Priorities for Global Chemical Companies in 2026

  • Build a jurisdiction-by-jurisdiction compliance calendar: Map EU, UK, Turkey, Ukraine, U.S. and Latin America deadlines by product, substance and legal entity.

  • Prioritize data readiness: Review substance identity, tonnage bands, hazard data, exposure information, emissions estimates and SDS/label content.

  • Align registration and labeling projects: Coordinate chemical registration work with classification, SDS, label and supply chain communication updates.

  • Monitor transitional rules: Pay close attention to extended deadlines, interim registration routes, grace periods and market-specific transition arrangements.

  • Strengthen supply chain communication: Confirm who is responsible for registration, reporting, notifications, import roles and downstream communication in each market.
