Understanding China's Dangerous Chemicals Catalog (2015) in International Shipping
For overseas buyers sourcing chemicals or finished goods from China, compliance starts with correctly classifying products against China's Dangerous Chemicals Catalog (2015 Edition). This catalog is the primary regulatory list used by Chinese authorities to determine whether a substance or mixture falls under "dangerous chemical" management — directly impacting how it can be shipped via ocean or air freight from Chinese ports and airports.
Key Structure & Scope
The catalog includes 2,828 entries covering:
- Specific chemical names and common synonyms
- Certain generic groups (e.g., "synthetic resins containing flammable solvents")
- Concentration thresholds that trigger classification when substances appear in mixtures
Critical Note: Unlike some international lists, the catalog relies primarily on Chinese nomenclature + concentration, not CAS/UN numbers alone. Even if a CAS number matches, the official Chinese name and threshold rules prevail for export declarations and transport approvals.
How Classification Affects Transport
If a product is listed (or contains listed components above threshold), it generally requires:
- Proper GHS classification aligned with China's GB standards
- A valid Safety Data Sheet (SDS) accepted by Chinese carriers and customs
- Correct transport documentation (e.g., DGD for air, IMO Declaration for sea)
- Carrier acceptance procedures — many Chinese forwarders will reject undeclared or misclassified dangerous goods
Important: Even non-listed substances may still need hazard evaluation if they meet GB hazard criteria (physical, health, environmental). Exemptions exist for low concentrations, certain intermediates, and materials already regulated under explosives/radioactive frameworks.
Practical Export Scenarios
From an international logistics perspective, two technical reports commonly support compliance:
Chemical Hazard Classification Report
Used for domestic registration/licensing in China, relevant for production-site inspections before shipment.
Hazard Property Identification & Classification Report
Critical for export clearance, aligning Chinese hazard data with GHS and transport regulations (IMO/ICAO/IATA).
⚠️ Buyer Alert: Buyers should confirm their Chinese suppliers have these documents early — especially for air cargo, where screening is strict at major hubs like Shanghai, Shenzhen, and Hong Kong.
Recommendation
Before booking shipments out of China, verify:
- Whether any ingredients appear in the Catalog (2015) at reportable concentrations
- That SDS and test reports match both Chinese GHS and target-market requirements
- Carrier dangerous goods policies (including transshipment port rules)
Misclassification can lead to delays, redelivery costs, or penalties at Chinese Customs. Early hazard review is standard best practice for chemical logistics from mainland China.
