China Expands Its Hazardous Chemicals Inventory: What Chemical Compliance Teams Need to Know

For businesses operating within or exporting to the Chinese market, a critical update just dropped.
On April 16, 2026, China’s Ministry of Emergency Management (MEM), alongside nine other joint government departments, officially issued Announcement No. 3 of 2026. This announcement confirms the immediate addition of five new chemical substances to China’s rigorous Inventory of Hazardous Chemicals (2015 Edition).
Coming directly on the heels of China's newly enacted Hazardous Chemicals Safety Law (which went into effect on May 1, 2026), this move signals a broader wave of regulatory tightening across the nation.
Here is a breakdown of what was added, why it matters, and how your business should prepare.
The 5 Newly Added Substances
The MEM announced that China’s national Classification Information Table for Hazardous Chemicals is being updated to reflect these additions.
Companies handling any of the following five substances (regardless of volume) must take note of their corresponding CAS numbers and regulatory aliases:
No. | Chemical Name | Common Alias | CAS No. |
1 | 3-Chloropropyne | Propargyl chloride | 624-65-7 |
2 | 2-Iodoxybenzoic acid | IBX | 61717-82-6 |
3 | 4-Nitrobenzyl 2-diazoacetoacetate | — | 82551-63-1 |
4 | Methane sulfonyl azide | — | 1516-70-7 |
5 | 3-Methyl-2-nitrobenzoic acid | 2-Nitro-m-toluic acid | 5437-38-7 |
Immediate Regulatory Implications for Enterprises
Because this announcement takes effect immediately, there is no transitional grace period. Under State Council Decree No. 591 (Regulations on the Safety Management of Hazardous Chemicals), any enterprise involved in the production, storage, use, trade, or transportation of these chemicals inside China must instantly step up compliance.
If your supply chain touches these substances, you are now legally required to meet the following mandates:
1. Hazardous Chemical Registration
Any manufacturer or importer handling these five chemicals must register them with the National Registration Center for Chemicals (NRCC) under the MEM.
2. Administrative Licensing
Operating without a safety license is no longer an option. Depending on your business model, you may need to apply for or amend your:
Hazardous Chemical Production License
Hazardous Chemicals Safe Use License
Hazardous Chemical Trading/Operation License
3. Chinese-Language SDS and Labelling
Under Chinese law, suppliers must provide compliant, Chinese-language Chemical Safety Data Sheets (SDS) and appropriate GHS hazard safety labels. If you discover any newly unmapped hazardous properties for these substances, you are obligated to update your SDS and alert downstream users immediately.
4. Safe Transportation & Logistics
These materials must now be handled strictly under dangerous goods transport protocols. Under the new 2026 Hazardous Chemicals Safety Law, companies must also account for stricter oversight within Chemical Industrial Parks and adhere to enhanced safety assessment reporting requirements every three years.
Action Steps for Supply Chain Managers
The cost of non-compliance in China has drastically increased under the new legal framework. To insulate your business from heavy fines, border rejections, or operational halts, implement these steps immediately:
Audit Your Inventory: Check your raw materials, intermediates, and final products against the 5 CAS numbers listed above. Remember to audit mixtures, as a formulation containing these ingredients could trigger hazardous status.
Update GHS Documentation: Coordinate with your regulatory affairs team or an external consultant (like the CIRS Group) to author or revise your Chinese SDS and labels to ensure they align with the updated national Classification Information Table.
Review Logistics Partnerships: Ensure that your logistics providers inside China are fully licensed to carry these newly designated dangerous goods.
The Bottom Line
China's approach to chemical management is becoming increasingly proactive and sophisticated. The rapid introduction of new substances to the Hazardous Chemicals Inventory (coupled with the sweeping powers of the new Safety Law) proves that reactive compliance is a risky strategy.
