A Complete Guide to Exporting Category 2.1 Dangerous Goods

PART 01 What are Category 2.1 Dangerous Goods?

Class 2 dangerous goods refer to gases, which include three subcategories: Category 2.1 (flammable gases), Category 2.2 (non-flammable, non-toxic gases), and Category 2.3 (toxic gases). This article will primarily focus on exploring and explaining Category 2.1 dangerous goods.

Category 2.1 dangerous goods primarily refer to flammable gases. Common products in this category include aerosol items such as insecticide sprays, automotive spray paints, hairsprays, sunscreen sprays, as well as industrial gases like methane, hydrogen, and oxygen. For the export of such goods via sea freight, strict compliance with regulations for the transport of dangerous chemicals is mandatory; failure to do so may result in shipment refusal.

PART 02 Export Procedure Breakdown

1. Pre-export Compliance Preparation

An Import and Export License must be obtained from the State Administration for Market Regulation; shipments are prohibited without this certificate. Application is recommended to be initiated 2-3 months prior to shipment to prevent delays.

2. Booking & Customs Declaration

Select declaration methods based on cargo characteristics:

Bottled/Liquid Cargo Separate Declaration: Steel cylinders requiring "in-first, out-last" or "out-first, in-last" handling must be declared individually.

Limited Quantity Exemption: UN1950 classified goods (e.g., certain aerosol products) may qualify for limited quantity packaging exemptions, bypassing Dangerous Goods Packaging Certificate review. Verify compliance with the latest exemption policies.

3. Dangerous Goods Declaration

Core required documents include:

 -MSDS (Material Safety Data Sheet): Must be the latest version.

 -Dangerous Goods Packaging Certificate: Confirm packaging meets Category II/III standards and aligns with current packaging regulations.

 -Commodity Inspection Certificate: Quarantine approval proof; monitor destination country's updated inspection requirements.

 -Transport Condition Identification Report: Issued by authorized institutions.

 -Classification Verification Report: Confirm 2.1 classification accuracy to avoid rejection due to misdeclaration.

PART 03 Packaging & Labeling Requirements

-Composite Packaging Structure:

Inner Packaging: Glass/plastic bottles (pressure-resistant, leak-proof, and compliant with latest pressure testing standards).

Outer Packaging: Steel-framed pallets or corrugated fiberboard boxes (maximum single unit weight: 30kg for general materials, 20kg for fragile substances; strictly adhere to current weight restrictions).

-Labeling Compliance:

Display Category 2.1 Dangerous Goods Markings (must conform to latest International Dangerous Goods (IDG) marking standards).

Minimum text height: 12mm; orientation must align parallel to packaging surfaces (illegible or misaligned text will result in non-compliance).

PART 04 Latest Policies & Compliance Guide

-Tariff Optimization Strategies: Proactively verify destination country tariff rates and prepare legal documents (e.g., tax invoices, certificates of origin) to leverage duty reductions. Monitor RCEP and other FTA tariff preferences for updates.

-Quality Assurance Compliance: Mandatory testing by CNAS-accredited third-party laboratories (e.g., SGS, CTI). Reports remain valid for 12 months; ensure compliance with updated testing standards to avoid expiration-related shipment delays.

General Cargo Exemption Tactics: Certain products (e.g., Oxygen, Nitrous Oxide) may qualify for general cargo classification through packaging adjustments, but confirm destination country acceptance criteria beforehand.

Limited Quantity Packaging Standards:

Category II Packaging: Single unit max 30kg; inner packaging volume ≤1L (for high-risk flammable gases like Hydrogen).

Category III Packaging: Single unit max 30kg; inner packaging volume ≤5L (for low-risk aerosols like sunscreen sprays).

Regularly review updated limited quantity exemption policies to prevent compliance violations.
