Automotive fluids are ordinary cargo most of the time, but the classification and documentation errors around them are the ones that hold shipments at port. This is what an importer should confirm before the first order ships.
Harmonised System classification
The six-digit HS code is set by the World Customs Organization and is the same in around 200 countries. That is the part you can rely on. Beyond six digits, each country's national tariff applies, and your customs broker confirms the final code against the actual formulation and retail packaging.
| Product | Six-digit HS heading | Heading description |
|---|---|---|
| Engine coolant / antifreeze | 3820.00 | Anti-freezing preparations and prepared de-icing fluids |
| Windshield washer fluid | 3402.20 | Surface-active preparations put up for retail sale |
| Diesel exhaust fluid (AdBlue) | 3102.10 | Urea |
| Manual transmission fluid / gear oil | 2710.19 | Petroleum oils, other than crude — other |
| Power steering fluid | 2710.19 | Petroleum oils, other than crude — other |
| Brake fluid (DOT3 / DOT4) | 3819.00 | Hydraulic brake fluids |
| Anti-rust / penetrating lubricant spray | 3403.19 | Lubricating preparations — other |
| Hand cleaner paste | 3401.30 | Skin-washing organic surface-active products, retail |
Safety data sheets (SDS / MSDS)
Every formulation needs its own SDS in the GHS 16-section format, in a language the destination accepts, and dated. A single generic MSDS covering the whole range is not sufficient for customs, and it is not sufficient for your customers' own compliance obligations.
What to check in the SDS your supplier sends
- Section 1 identifies the exact product name and the supplier's emergency contact, not a generic group name.
- Section 3 lists hazardous constituents with CAS numbers and concentration ranges.
- Section 9 gives real physical data: pH, boiling point, flash point, density, appearance.
- Section 14 states transport classification, UN number and packing group where applicable.
- The revision date is recent and the sheet matches the formulation you are actually buying.
Is it dangerous goods?
| Product | Typical transport status |
|---|---|
| Ethylene glycol coolant | Usually not classified as dangerous goods for transport; check national rules |
| Windshield washer fluid | Usually not regulated, unless it contains a significant methanol content |
| Brake fluid | Generally not dangerous goods for transport, though some national rules add requirements |
| Diesel exhaust fluid | Not dangerous goods, but corrosive to some metals in storage |
| Aerosol anti-rust / penetrating spray | Classified — UN1950, Aerosols, typically Class 2.1 flammable gas, limited quantity provisions may apply |
Documents to request with every shipment
- Commercial invoice and packing list matching the carton structure exactly
- SDS for each formulation, current revision
- Certificate of Origin for preferential duty treatment where an FTA applies
- Certificate of Analysis (COA) for the specific production batch, showing freeze point, boil point, pH, density and reserve alkalinity
- Third-party test reports where an approval or national standard is claimed, for example ASTM D1384 and D4340
- For private label: artwork approval, label proof and any destination-country registration references
A pre-shipment checklist
- 1Confirm the HS code with your own broker against the real formulation, not against the marketing name.
- 2Check whether the destination requires product registration, labelling in a specific language, or a local importer of record.
- 3Verify SDS currency and that every SKU in the order has its own sheet.
- 4For aerosols, confirm dangerous goods acceptance with the forwarder before booking.
- 5Check the shelf life remaining on arrival — coolant and DEF both age, and sea freight plus storage eats into the window.
- 6Confirm the COA will be issued per batch, not per year.
