Clarifying Compliance in Chemical Ocean Shipping: The Critical Distinction Between Dangerous Goods (DG) and Hazardous Chemicals (HazChem) & Their Declaration Responsibilities
Dear International Trade Partners, Procurement Specialists, and Logistics Colleagues,
In the logistics of international chemical shipments, particularly for exports from China, confusion between "Hazardous Chemicals" and "Dangerous Goods" is a common compliance risk. This misunderstanding can lead to incorrect declarations, unnecessary delays, and even regulatory penalties. This article aims to clearly explain the core differences between these two categories and their corresponding regulatory frameworks in China to help ensure your supply chain operates smoothly and compliantly.
The Key Difference: Two Independent Regulatory Systems
In China, these two concepts fall under parallel yet independent legal and regulatory systems, with distinct criteria and governing authorities:
| Aspect | Hazardous Chemicals (HazChem) | Dangerous Goods (DG) |
|---|---|---|
| Definition Basis | The official "Catalogue of Hazardous Chemicals" (2015 Edition). Identifies substances based on intrinsic hazardous properties (e.g., health hazards, environmental hazards), primarily referencing the UN Globally Harmonized System (GHS). | Internationally recognized transport regulations: IMDG Code (ocean) and IATA DGR (air). |
| Governing Authority | China Customs | Maritime Safety Administration (MSA) for ocean freight or Civil Aviation Administration (CAAC) for air freight. |
| Regulatory Focus | Mandatory control over the import and export of all chemicals listed in the catalog. Core requirement: Provide and verify China-compliant "SDS and Label" (Safety Data Sheet and Safety Label). Key Takeaway: Regardless of DG status, if listed in the Catalog, declaration to China Customs is mandatory. |
Managing "goods" that pose a safety risk to transport (e.g., flammable, explosive, corrosive, toxic). Involves proper classification, packaging, marking, labeling, stowage, and declaration. Key Takeaway: Sole criteria are international transport codes. No direct correlation with China's Hazardous Chemicals Catalog. |
Analysis of a Recent Case
A recent enforcement case by Chinese maritime authorities sparked discussion: A shipment of "Diphenylmethane diisocyanate" was declared as "general cargo."
- Fact Check: The product is indeed listed in the Catalogue of Hazardous Chemicals, making it a "Hazardous Chemical" subject to Customs control.
- Compliance Analysis: However, based on its GHS classification in the provided SDS, the product is not defined as a "Dangerous Good" under the IMDG Code. Therefore, the shipper's failure to declare it as dangerous goods to the maritime authorities was not a violation from a transport safety perspective. Its obligation as a "Hazardous Chemical" should have been fulfilled entirely with Customs.
Practical Guidance for Your Operations
Dual Verification: When procuring or shipping chemicals from China, a two-step determination is essential:
- Step 1 (Compliance): Check if the product is listed in China's Catalogue of Hazardous Chemicals. If yes, you must prepare a China-GHS compliant SDS and label, and ensure your supplier or freight forwarder completes the "Hazardous Chemical" import/export declaration with China Customs.
- Step 2 (Transport): Based on accurate technical data, strictly determine the Dangerous Goods classification according to the IMDG Code (Ocean) or IATA DGR (Air). Only items defined as dangerous goods by these regulations require a separate dangerous goods transport declaration to the maritime/aviation authorities.
Clear Accountability: Understand that Customs' "Hazardous Chemical Control" and MSA/CAAC's "Dangerous Goods Transport Control" are two separate procedures. A product may fall under both, or only one. Clarifying the responsible authority is key to avoiding declaration errors.
Conclusion
In short:
- Customs governs "HazChem" (based on intrinsic hazards per the Catalog).
- MSA/CAAC governs "DG" (based on transport safety risks per international codes).
Ensuring your logistics provider clearly understands this distinction and correctly interfaces with both Customs and the transport regulators is fundamental to the lawful and efficient export of your chemical goods from China. Any conflation of these responsibilities can lead to unnecessary customs clearance delays or shipment disruptions.
