China's Hazardous Chemicals Safety Law 2026: What Foreign Companies Need to Know

China’s new Hazardous Chemicals Safety Law marks an important shift in the country’s chemicals regulatory framework. Adopted on December 27, 2025, and effective from 1 May 2026, the law is presented as the supreme law in the field of hazardous chemical safety management. That matters because it brings together multiple compliance expectations into a clearer, more formal legal framework with wider business implications.

China Hazardous Chemicals Safety Law: At a Glance

• Effective: May 1, 2026
• Applies to: production, storage, use,  and transportation of hazardous chemicals
• Covers both domestic and imported hazardous chemicals
• Introduces lifecycle-based compliance expectations
• Reinforces China GHS requirements
• Expands focus on digital traceability and QR-code systems
• May trigger registration and licensing obligations depending on product status

Why the New Law Matters

What makes this law especially significant is its breadth. It does not focus on just one point in the supply chain. Instead, it covers the full lifecycle of hazardous chemicals, including production, storage, use, operation, and transportation. For businesses, that means compliance can no longer sit in one silo. Compliance responsibilities may now extend beyond EHS teams and involve product stewardship, import/export operations, warehousing, logistics, labeling, customer support, and corporate governance.

Another reason the law matters is the way hazardous chemicals are identified. The law introduces three routes:

1. Inclusion in the Catalogue of Hazardous Chemicals,
2. Formal identification of hazardous characteristics, or
3. Meeting the criteria for hazardous chemicals across a broad range of hazard categories.

This is important because some businesses may assume they are outside scope if a substance is not explicitly listed in the catalogue, when in practice classification-based triggers may still create compliance duties.

The distinction between registration and licensing is also critical. Under the new framework, if a product is deemed hazardous under the Catalogue or by identification, companies may need to meet both registration and licensing obligations. If it is determined to be hazardous under the broader criteria route, registration obligations still apply.

Why Foreign Companies Should Pay Attention

While many regulatory obligations sit with Chinese importers, manufacturers, or distributors; overseas suppliers often play a critical role in supporting classification, safety data sheets, labels, registration activities, and hazard communication. Companies exporting chemicals to China are often expected to provide classification support, Chinese-language safety data sheets, labels and other product information needed by customers and supply-chain partners.

This law is particularly relevant for chemical manufacturers, specialty chemical suppliers, importers, exporters, distributors, contract manufacturers, and product stewardship teams. Businesses supplying intermediates, additives, coatings, electronic chemicals, and formulated products should review how their products are classified under the Chinese framework and whether obligations may apply.

For many European and UK companies, this is especially important because market access increasingly depends on the quality and availability of local compliance documentation. Even where the legal obligation sits with a Chinese entity, overseas suppliers are often expected to provide the information needed to demonstrate compliance. Gaps in documentation, classification, or product stewardship can create delays, customer concerns, and commercial disruption long before any formal enforcement action occurs.

Compliance is Becoming More Digital

The law also reinforces the importance of China-specific hazard communication. China GHS requirements include classification under the GB 30000 series, safety data sheets under GB/T 17519-2013, GB/T 16483-2008, and GB 30000.1-2024, and labels under GB 15258. All documentation must be prepared in Chinese and aligned with local requirements.

For overseas companies, that is a reminder that global SDSs and labels cannot simply be reused unchanged for China. Documentation quality, localisation, and standard alignment remain essential to market access.

The law also reflects China’s broader move towards digital compliance and traceability. The “one enterprise, one product, one code” QR-code approach has already been implemented by local authorities in places such as Shanghai, Beijing, Shandong, and Guangdong. This links hazardous chemicals to QR-code-based traceability systems. While implementation is not yet uniform nationwide, the direction is clear: regulators are expecting better product-level traceability and more accessible compliance information throughout the supply chain.

What About R&D Materials?

There is also a potential note of opportunity for innovation-led businesses because the law indicates that low-volume, low-release, and low-exposure substances used for R&D, trial production, or trial sales may qualify for registration exemption, although we are still waiting for the specific measures to be developed by the relevant authorities. That means companies should watch closely for implementing rules rather than assuming every R&D material will be treated the same as a fully commercial product.

For many companies, the real significance of the 2026 law is not that every obligation is brand new, but that the framework is becoming more explicit, more integrated, and more enforceable across the chemical lifecycle. Businesses that review portfolios, confirm classification logic, assess registration and licensing exposure, and strengthen China-specific hazard communication now will be in a much better position to manage risk and maintain continuity in 2026.

What Companies Should Do Now

• Review products against China's hazardous chemical determination criteria;
• Assess whether registration or licensing obligations may apply;
• Verify Chinese SDSs and labels against current GB/EU standards;
• Confirm importer and distributor responsibilities;
• Evaluate readiness for QR-code and traceability requirements;
• Monitor developments around R&D registration exemptions (if relevant); and
• Align regulatory, supply chain, and commercial teams.

As China continues to strengthen hazardous chemicals management, companies involved in manufacturing, importing, exporting, distributing, or using chemicals in China should review their compliance strategies now. Early preparation can help reduce regulatory risk, avoid supply chain disruption, and support continued market access.
