On 2026年5月1日, the Hazardous Chemicals Safety Law officially comes into effect. This is the first time China has systematically established, in the form of law, a full-chain safety management responsibility system for hazardous chemicals, directly affecting chemical export enterprises, cross-border supply chain service providers, and importers serving markets such as the EU REACH, the U.S. TSCA, and Southeast Asia SGS. After the implementation of this law, products that have not completed overseas agent filing, whose GHS labels or multilingual SDS adaptations are non-compliant, face the risk of being returned or rejected by overseas customs. Relevant enterprises need to immediately assess their existing export procedures and the validity of compliance documents.

Incident Overview

The Hazardous Chemicals Safety Law will officially take effect on 2026年5月1日. The law clarifies the legal responsibilities related to hazardous chemicals in production, storage, use, operation, transportation, export declaration, packaging, GHS labeling, multilingual adaptation of Safety Data Sheets (SDS), overseas agent filing, and other links, covering full-chain management requirements from domestic sources in China to overseas end receipt. According to currently disclosed public information, the applicable entities of the regulation include enterprises engaged in hazardous chemical import and export activities within China, as well as their designated overseas agents; enforcement shall be subject to the legal text itself and subsequent supporting implementation rules.

Which Sub-sectors Will Be Affected

Direct trading enterprises: As the main entity for export declaration, they need to bear statutory responsibilities for GHS labels, multilingual SDS versions (including the official language of the target market), transport packaging compliance, and overseas agent filing. The impact is reflected in longer document preparation cycles, earlier compliance review checkpoints, and increased risk of export customs clearance failure.

Raw material procurement enterprises: If purchasing intermediates or formulated products containing hazardous chemical components, they need to obtain SDS and label materials from upstream suppliers that meet the new law requirements, and verify whether they cover the target market language and classification standards. The impact is reflected in greater pressure on supplier qualification review and the need to renegotiate compliance clauses in procurement contracts.

Processing and manufacturing enterprises: Production enterprises involving hazardous chemicals in reaction, storage, or repackaging must ensure that the final packaging identification, accompanying documents, and legal requirements of export products are consistent. The impact is reflected in the need to simultaneously upgrade production line label printing systems, SDS generation processes, and export batch file management.

Channel distribution enterprises: As non-manufacturing export entities (such as foreign trade agents and brand-side ODM/OEM service providers), they need to confirm whether the principal has completed overseas agent filing and conduct a formal review of the labels and SDS content of the products they represent. The impact is reflected in the need to clearly define compliance responsibility allocation in agency service agreements, otherwise they may bear joint legal liability.

Supply chain service enterprises: Including international freight forwarders, hazardous chemicals logistics service providers, compliance consulting institutions, etc., they need to adjust service content according to the new law, such as providing localized GHS label production, multilingual SDS preparation, and assistance with overseas agent registration. The impact is reflected in the need for service standards to align with mandatory legal requirements, and previous standardized service templates may no longer be applicable.

What Key Points Should Relevant Enterprises or Practitioners Focus On, and How Should They Respond at Present

Pay attention to subsequent supporting implementation rules and official interpretation trends

This law is a higher-level law, and the specific enforcement scale depends on the supporting regulations, technical guidelines, and interpretive documents of competent authorities (such as the Ministry of Emergency Management and the General Administration of Customs) to be issued soon. What is currently more worth attention is whether operational documents such as the Hazardous Chemicals Export Compliance Operation Guidelines or the Detailed Rules for the Implementation of Overseas Agent Filing will be issued within the second quarter of 2026.

Focus on key export markets and high-risk categories for compliance screening

Priority should be given to sorting out the lists of hazardous chemicals exported to the EU (correlation with SVHC notification under REACH), the U.S. (TSCA inventory matching and extension of importer responsibilities), and Southeast Asia (common SGS inspection items such as UN numbers and transport categories); at the same time, identify categories likely to trigger label/SDS disputes, such as organic solvents, corrosive inorganic salts, and flammable liquid mixtures.

Differentiate between the legal effective date and the actual business implementation pace

2026年5月1日 is the date the law takes effect, but some requirements (such as the launch of the overseas agent filing system and the activation of new customs declaration fields) may have a transition period. Based on analysis, enterprises should not assume that “all links will switch immediately after 5月1日”, but should instead follow the system update schedule published by platforms such as customs and emergency management departments, to avoid misreporting caused by systems not being ready.

Start multilingual SDS adaptation and label template updates in advance

The SDS must cover the official language of the target market (for example, the EU requires at least one of German, French, Spanish, or Italian; the U.S. requires English; Thailand requires Thai), and the content must be consistent with the latest revised version of GHS (10th edition). At present, a more appropriate understanding is that enterprises need to complete the first batch of key product SDS rewrites and label proofing verification before 4月, leaving time for internal review and printing cycles.

Editor’s Viewpoint / Industry Observation

Observably, the implementation of this law marks a shift in China’s hazardous chemicals regulatory logic from “domestic safety control” to “cross-border responsibility extension throughout the entire life cycle.” It is more like a strong binding signal rather than a simple technical adjustment——because the elevation to the legal level means stronger enforcement rigidity, enhanced cross-departmental coordination mechanisms (emergency management, customs, ecology and environment), and a substantive increase in the cost of violations for enterprises. Analysis shows, in the short term, enterprises face the challenge of compliance response speed; in the medium to long term, it will accelerate the professional division of labor among hazardous chemicals export enterprises, for example, the role of overseas agents may be routinely undertaken by professional third-party institutions. What the industry needs to continuously pay attention to is whether customs authorities in different regions will unify the determination standards for situations such as “non-compliant labels” and “missing SDS items”, and whether overseas market regulators will accordingly adjust the intensity of market access review for Chinese export products.

Conclusion: The implementation of the Hazardous Chemicals Safety Law is not a routine regulatory update, but a structural upgrade of China’s hazardous chemicals export compliance framework. It does not change the technical properties of the products themselves, but reconstructs the boundaries of enterprises’ cross-border responsibilities. At present, it is more appropriate to understand it as: compliance has shifted from an “optional item” to a “statutory action”, and the granularity of execution has sunk to the label and document level of individual SKUs. The key to rational response lies in transforming legal requirements into specific operational items that are verifiable, traceable, and auditable, rather than merely staying at the level of policy communication or supplementary document signing.

Source note: Mainly based on the legal text of the Hazardous Chemicals Safety Law (effective from 2026年5月1日) and public information from the State Council policy briefing; matters such as supporting implementation rules, the launch time of the filing system, and changes to customs declaration fields are still pending further official clarification and remain subject to continuous observation.
