Auto parts distributors, repair shops and exporters often ship a mix of ordinary parts and regulated products on the same order. Hidden in that mix are dangerous goods that carriers will reject if they are not declared. Miami is a major hub for automotive parts exports to Latin America and the Caribbean, so getting this right matters.
Common automotive hazmat
- Aerosols. Brake cleaner, carburetor spray, lubricants, tire shine and starter fluid are often aerosols (UN1950), many of them flammable. See our aerosol shipping guide.
- Batteries. Lead-acid batteries are corrosive; lithium batteries in key fobs, jump starters and tools have separate rules. Start with wet battery rules.
- Flammable liquids. Gasoline additives, solvents, paints, adhesives and thinners are usually Class 3. Our post on paint, coatings and adhesives covers classification.
- Corrosives. Battery acid, some cleaners and rust removers.
- Airbag modules and inflators. Modules and inflators are regulated, and recalled inflators carry additional restrictions. Our background article on airbag disposal offers context.
- Compressed gas. Refrigerant cylinders and shop gases are Class 2; see compressed gas cylinders.
Some products are not regulated for ground transport but are for air or ocean. Motor oil, for example, is typically not a hazardous material in standard packaging, but used oil, contaminated fluids and other products may be. Ethylene glycol antifreeze can be regulated when it meets specific reportable-quantity thresholds in larger packages. Always check the SDS and the current regulations.
Parts that surprise people
Even “dry” parts can carry hazards. Parts containing residual fuel, such as fuel pumps, tanks and carburetors, may be regulated if not properly drained. Electric vehicle components, including battery modules, require lithium battery compliance. Airbags and seat belt pretensioners contain pyrotechnic components.
Classification workflow
- Gather the SDS for every chemical and electronic product.
- Identify the hazard class, UN number, proper shipping name and packing group from Section 14.
- Determine whether limited quantity provisions apply based on inner packaging size.
- Select compliant packaging and mark it correctly.
- Choose the mode, because air has the strictest quantity limits.
- Prepare shipping documents and train your staff.
Tools such as freight class lookups help with pricing, but classification must come first.
Export from South Florida
Export shipments add IMDG or IATA rules and often destination-specific restrictions. Many distributors consolidate mixed pallets, which brings segregation requirements into play. Read our articles on exporting hazmat to Latin America and the Caribbean and IATA certification in South Florida. A consolidator that is not hazmat-capable may refuse the whole pallet over one aerosol can.
How Go Hazmat can help
Mixed-SKU shipments are exactly where a hazmat 3PL adds value. We can pull regulated items from a pallet, repack them, create compliant paperwork, and ship them by the right mode with your general freight. See our LTL services and hazmat warehousing, or ask for a quote.
Frequently asked questions
Is brake cleaner hazmat?
Often yes. Many brake cleaners are flammable aerosols and are regulated under UN1950 unless they meet an exception. Check the SDS for flammability and quantity limits.
Can I ship airbags?
Airbag modules and inflators are regulated and subject to strict packaging and documentation rules, and recalled units have additional restrictions. Consult a hazmat professional before shipping.
Is motor oil hazardous for shipping?
New motor oil is generally not regulated as a hazardous material for transportation, but conditions, packaging, quantity and contamination can change that. Used oil and mixed fluids need review.
