An HS code (Harmonized System code) is a standardized numeric code used by customs authorities worldwide to identify exactly what product is being shipped. For auto spare parts, the HS code determines the import duty rate your shipment is charged and whether any additional permits are required — so getting it wrong can mean unexpected costs or a shipment held at customs.
Why HS codes matter for spare parts buyers
Every country's customs authority uses HS codes to classify goods, calculate duties and taxes, and apply any import restrictions. If a supplier lists the wrong HS code — or leaves it out entirely — your shipment can be:
- Charged the wrong duty rate (sometimes higher than necessary)
- Flagged for manual inspection, delaying delivery
- Rejected at customs until the documentation is corrected
This is why HS codes should always appear on the Commercial Invoice and Packing List, not just be something you figure out after the goods arrive.
Where auto parts fall in the HS system
The Harmonized System groups vehicle parts primarily under Chapter 87 — Vehicles other than railway or tramway rolling stock, and specifically under heading 8708 — Parts and accessories of motor vehicles. Within 8708, sub-headings break parts down further, for example:
- Brakes and servo-brakes and their parts
- Gear boxes and parts
- Drive-axles and parts
- Suspension shock-absorbers
- Radiators
- Silencers and exhaust pipes
- Clutches and parts
- Steering wheels, columns, and boxes
Some components — like electrical parts (Chapter 85) or certain filters — may fall outside Chapter 87 entirely, depending on the specific item. This is exactly why a blanket "auto parts" HS code doesn't exist; classification is done part by part.
A practical example
A front shock absorber for a passenger vehicle typically falls under HS code 8708.80 (suspension systems and parts). An oil filter, by contrast, is usually classified under 8421.23 (filters for internal combustion engines) rather than under Chapter 87 at all. This is a good illustration of why relying on your supplier's documented HS code — rather than guessing based on the general product category — matters.
What to ask your supplier for
Before your shipment leaves the country of origin, confirm that:
- Each line item on the Commercial Invoice and Packing List has its own HS code (not one generic code for the whole shipment)
- The HS code matches the specific part type, not just "auto parts" broadly
- You have the Certificate of Origin, which your customs broker will use alongside the HS code to determine preferential duty rates under any applicable trade agreements
A note on accuracy
HS code classification can vary slightly between countries, since each customs authority maintains its own tariff schedule built on the international HS framework. If you're unsure how a specific part will be classified in your country, it's worth confirming with your local customs broker before the shipment arrives — your supplier's HS code is a strong starting reference, but the importing country's customs authority always has final say.
