Aerosol Shipping Guide: How to Export Class 2.1 Dangerous Goods Internationally — Full Compliance, Documentation & Customs Tips

Why are aerosols classified as dangerous goods?

Aerosol products contain propellant gas under pressure — typically propane, butane, or DME (dimethyl ether). This makes them flammable and potentially explosive if mishandled.

Under the UN Model Regulations, aerosols fall under:

• **UN 1950** — the specific UN number for aerosol dispensers

• **Class 2.1** — flammable gases

• **Packing Group** — none assigned (special provision 63 applies)

This classification is consistent across all major frameworks: the International Maritime Dangerous Goods (IMDG) Code for sea freight, IATA Dangerous Goods Regulations for air freight, and ADR for European road transport.

**Important nuance**: Some very small aerosols (< 50 ml) or non-flammable formulations may qualify for Limited Quantity (LQ) exemptions, reducing documentation requirements. But this varies by destination country and mode of transport.

What documentation do I need to ship aerosols from China?

Shipping aerosols from China requires a specific set of documents. Missing any one can delay your shipment at the port or result in fines.

Required documents:

• **Material Safety Data Sheet (MSDS/SDS)**: Must comply with GHS Rev.6+ format. Your manufacturer should provide an MSDS for each product. The MSDS must include Section 14 (Transport Information) listing the UN 1950 designation.

• **Dangerous Goods Declaration (DGD)**: A formal document certifying that the shipment is packed, labeled, and declared according to IMDG/IATA regulations. Must be signed by a certified DG agent.

• **Certificate of Dangerous Goods (海运危包证 / Weibaozheng)**: Issued by Chinese authorities (usually CIQ or a UN-approved testing lab) certifying that the packaging meets UN performance standards. Without this, Chinese customs will not release the container.

• **UN Performance Packaging Certificate**: Documents the packaging type (steel, aluminum, or plastic) and its tested performance level.

• **Certificate of Origin**: Required for tariff preference under Free Trade Agreements. For EU, a EUR.1 certificate or statement on origin may be needed.

• **Packing List & Commercial Invoice**: Both must state "Dangerous Goods — UN 1950 Class 2.1" prominently on the document.

**Pro tip**: A good OEM factory will have a dedicated logistics team that prepares most of these documents. Ask your manufacturer if they can provide the MSDS and 危包证 as part of the standard order — some charge extra, others include it.

Sea freight vs air freight: which works for aerosol products?

Sea freight is the standard and most cost-effective method for shipping aerosol products internationally.

Sea freight (recommended):

• 20ft or 40ft container, fully DG-compliant

• Typical transit: 25-35 days China to Europe, 18-25 days to US West Coast, 30-40 days to South America

• Container must be marked with DG placards on all four sides

• Limited Quantity (LQ) exemption may reduce costs: aerosols up to 1 liter per unit, max 30 kg gross per inner package — no DG placard needed

• Cost: roughly $0.15-$0.40 per can for ocean freight (varies widely by destination and volume)

Air freight (expensive, emergency only):

• Strict IATA regulations — each piece must be individually tested and labeled

• Much higher cost — typically 5-10x sea freight

• Limited to small samples or urgent restocking

• Many airlines refuse aerosol shipments entirely

**Rule of thumb**: If your order is over 500 cans, use sea freight. For samples under 50 cans, use express couriers (DHL/FedEx) who accept DG shipments with proper paperwork — they're faster and less paperwork-heavy than full air freight.

How do customs clearance requirements differ by region?

Each destination region has its own import requirements for aerosol products. Here's what to expect:

European Union (EU):

• REACH compliance is mandatory — your manufacturer must register or have an Only Representative (OR) in the EU

• CLP regulation requires GHS-compliant labeling in the local language(s)

• VOC limits vary by country (Germany and France are strictest)

• The EU's F-Gas Regulation may restrict certain propellants

United States:

• EPA regulations apply — aerosol products must comply with VOC limits set by the EPA and CARB (California)

• CPSC (Consumer Product Safety Commission) requires child-resistant closures for certain products

• DOT (Department of Transportation) regulates the shipping documentation

• Importers need a US-based importer of record

Latin America (Mexico, Argentina, Chile, Brazil):

• INMETRO (Brazil) or NOM (Mexico) certification may be required

• Customs clearance can take 2-4 weeks — paperwork errors cause significant delays

• Spanish-language labeling is mandatory

• Local agent representation is strongly recommended

Middle East (UAE, Saudi Arabia, Qatar):

• ESMA (UAE) or SASO (Saudi Arabia) certification required

• Arabic labeling mandatory

• Some countries (e.g., Saudi Arabia) require pre-shipment inspection by approved agencies (SABER system)

• Halal-certified propellants may be required for certain products

**What a good OEM does**: At Huotian, we maintain regulatory databases for our key markets. When you place an order for Germany, we ensure the MSDS is in German, the label meets CLP requirements, and the formulation complies with EU VOC limits. This is the kind of service you should expect.

What packaging standards apply to aerosol shipments?

Aerosol packaging must pass UN performance tests before it can be used for international shipping. The tests simulate real transport conditions:

• **Drop test**: Package dropped from 1.2m onto a hard surface

• **Stacking test**: Must withstand stacking for 24 hours

• **Leakproofness test**: Internal pressure test for leaks

• **Hydraulic pressure test**: For inner receptacles

The packaging must be marked with the UN packaging code, e.g.:

`UN 1A2/Y1.2/100/18/CN/1234`

Breaking this down: 1A2 = steel drum with removable head; Y = Packing Group II (medium danger); 1.2 = specific gravity; 100 = hydraulic pressure in kPa; 18 = year of manufacture; CN = country; 1234 = manufacturer code.

**For containers**: The aerosol master cartons should be loaded into a shipping container with proper dunnage (bracing) to prevent movement during transit. Each carton must carry the UN 1950 hazard label.

**Limited Quantity (LQ) exemption**: If the inner packages (individual aerosol cans) are ≤ 1 liter each and the gross weight per inner package is ≤ 30 kg, the shipment may qualify as Limited Quantity — marked with the LQ diamond symbol instead of full DG placards. This reduces freight costs and paperwork.

What are the most common shipping mistakes importers make?

Based on our experience working with distributors in 26+ countries, these are the most frequent (and costly) mistakes:

1. Assuming the factory handles everything — then finding out they don't.

Not every aerosol manufacturer has DG shipping experience. Some small factories produce aerosols but have never exported. Always confirm: "Can you provide the MSDS and 危包证 for this product?" before placing an order.

2. Using a forwarder who doesn't understand DG.

General freight forwarders may accept your container but fail to properly declare it. This results in: container held at port, fines, or worse — an incident during transit. Always use a DG-certified freight forwarder.

3. Ignoring destination country regulations.

Your Chinese MSDS is valid for export from China, but the destination country may require a locally-compliant MSDS in the local language. This is especially true for EU (REACH) and Latin American countries.

4. Underestimating transit time.

DG shipments take longer. Customs at both ends inspects DG containers more thoroughly. Add 5-10 days to your estimated delivery time compared to non-DG cargo.

5. Not budgeting for DG documentation fees.

Expect additional costs: MSDS preparation ($50-200 per product), 危包证 ($100-500), DG declaration ($50-150), and DG container cleaning/disposal fees ($100-300). These are small relative to the total order value but should be budgeted upfront.

How do I verify a manufacturer's DG shipping capability?

Before committing to an OEM partner, ask these specific questions:

1. "Can you show me a recent MSDS for one of your products?"

A legitimate manufacturer should have an MSDS for every product. Check that Section 14 lists UN 1950, Class 2.1.

2. "Can you provide a sample 危包证 (Dangerous Goods Packaging Certificate)?"

This is the single most important document. If they can't produce it, they aren't exporting aerosols legally.

3. "Which countries have you shipped to in the last 12 months?"

A factory with real export experience will name specific destinations. If they say "we shipped to Europe" without naming countries, they may be exaggerating.

4. "What is your standard shipping process — FOB, CIF, or EXW?"

Reliable OEMs offer CIF (Cost, Insurance, Freight) — meaning they handle all shipping arrangements to the destination port. This is the safest option for first-time importers.

5. "Can you share a bill of lading (with commercial info redacted)?"

A manufacturer who regularly exports DG goods will have recent bills of lading to show. This is evidence that they actually move containers.

At Huotian, we ship to 26+ countries and handle full CIF arrangements. Our logistics team prepares all DG documentation in-house, and we provide MSDS in the destination language for all major markets.
