Important Update: China Adds Five Chemicals to Hazardous Material List – Impact on Ocean and Air Freight Shipments

This notice is to inform you of a critical regulatory update from China that will impact the international transportation of certain chemicals. As a global logistics partner based in Shenzhen, we are committed to keeping you informed and ensuring the safe, compliant movement of your goods.

1. Regulatory Announcement: Key Updates

On April 9, 2026, China's Ministry of Emergency Management and nine other government agencies jointly issued Announcement No. 3 of 2026. This regulation adds the following five chemicals to China's Hazardous Chemicals Directory (2015 Edition), effective immediately:

3-Chloroprop-1-yne (Propargyl chloride) CAS: 624-65-7
2-Iodoxybenzoic acid (IBX) CAS: 61717-82-6
2-Diazoacetoacetic acid 4-nitrobenzyl ester CAS: 82551-63-1
Methanesulfonyl azide (MsN3) CAS: 1516-70-7
2-Nitro-3-methylbenzoic acid CAS: 5437-38-7

Implications: This designation mandates that these substances are now formally regulated as hazardous materials for all activities in China, including production, storage, handling, and most critically for our industry – transportation and export.

2. Risk Profile and Safety Alerts

The inclusion of these chemicals is directly linked to several major industrial accidents in China between 2024 and 2025, resulting in significant casualties. These incidents underscore the inherent risks:

Thermal Instability and Explosive Potential: Chemicals like 2-Iodoxybenzoic acid (IBX), 2-Diazoacetoacetic acid 4-nitrobenzyl ester, and Methanesulfonyl azide possess molecular structures that can be thermally unstable and sensitive to shock or friction. Scientific data indicates high exothermic decomposition energy, posing a risk of violent decomposition or explosion under certain conditions (e.g., overheating during transport or improper handling).
Process Hazards: The production of 2-Nitro-3-methylbenzoic acid involves hazardous nitrification processes. Accidents have occurred due to process failures, leading to thermal runaway and explosion.

3. Critical Impact on International Logistics (Ocean & Air Freight)

If you are purchasing, shipping, or receiving any of these five chemicals from China, the new regulation triggers strict legal obligations under Chinese law, including the Regulations on the Safe Management of Hazardous Chemicals and the new Hazardous Chemicals Safety Law (effective May 1, 2026).

For all export shipments from China, the following are now mandatory:

Hazard Classification & Documentation: Each substance must have a definitive GHS classification. A compliant Safety Data Sheet (SDS) and hazard labeling/packaging meeting Chinese GHS and international transport regulations (IMDG Code for sea, IATA DGR for air) are required before booking.
Dangerous Goods (DG) Transport: These items can only be shipped as Classified Dangerous Goods. General cargo or declaration as "Not Restricted" is illegal.
Licensed Partners: Exporters must use licensed Dangerous Goods Freight Forwarders and carriers approved for the specific hazard class. Shippers must verify carrier DG qualifications.
Packaging & Marking: UN-certified packaging, proper hazard labels, and correct shipping names/UN numbers as per the IMDG Code or IATA DGR are essential.
Pre-Shipment Declarations: Accurate and complete DG documentation must be submitted to the forwarder and carrier well in advance for approval and slot booking.

Failure to comply will result in shipment rejection at origin ports/airports, significant delays, fines, and potential legal liability in the event of an incident.

4. Action Required for Importers & Supply Chain Managers

Verify Your Materials: Immediately check your Bill of Materials (BOM) and Safety Data Sheets (SDS) against the list above (CAS numbers are the key identifier).
Engage Your Supplier in China: Confirm that your Chinese supplier is aware of this new regulation and is taking steps to achieve full compliance for production, warehousing, and outbound logistics.
Consult Your Logistics Provider: Inform your freight forwarder early in the shipping process if any of these materials are involved. We can guide you and your supplier through the necessary steps for Dangerous Goods Declaration, documentation, and booking.
Plan for Impact: Build in additional lead time for DG approval processes, packaging procurement, and potential regulatory inspections.

Conclusion

This regulatory update reflects China's intensified focus on chemical safety following recent tragedies. Proactive identification and compliant handling of these newly listed hazardous materials are not just legal requirements but critical steps to ensure safety across the entire global supply chain.

We strongly recommend all stakeholders in the chemical logistics chain review this information carefully. Our team of Dangerous Goods Specialists is available to assist with classification, documentation review, and planning for compliant shipments via ocean or air freight.
