HS Code for Oil filter

Oil filters for internal combustion engines are classified under HS code 8421.23. This code is part of Chapter 84, which encompasses nuclear reactors, boilers, machinery, and mechanical appliances. Heading 8421 specifically covers centrifuges, including centrifugal dryers, and filtering or purifying machinery and apparatus for liquids or gases. Subheading 8421.23 is a specific provision for oil or petrol filters designed for use in internal combustion engines. This classification is determined by the function of the product—filtering liquids—and its specific application in automotive or industrial engines. Even if the filter is made of various materials like steel, paper, and rubber, its primary mechanical function as a component of an engine's lubrication system dictates its placement in Chapter 84 rather than under the constituent materials. The classification applies to filters for cars, trucks, ships, and stationary industrial engines, provided they are designed for oil or petrol filtration.

Products Included

• Spin-on oil filters for passenger vehicles
• Cartridge-type oil filter elements
• Bypass oil filters for heavy-duty machinery
• Full-flow oil filters for diesel engines
• Magnetic oil filters for industrial equipment

Common Misclassification

Oil filters are often confused with HS code 8421.29, which is a residual category for other liquid filtering or purifying machinery. While 8421.29 covers water filters or hydraulic fluid filters, 8421.23 is strictly for oil or petrol filters for engines. Another common mistake is using 8421.31, which is specifically for intake air filters for internal combustion engines. Importers must distinguish between the medium being filtered (liquid oil vs. air) to select the correct code. Furthermore, fuel filters are sometimes incorrectly placed here, though they are generally included if they are for petrol/oil as per the heading description.

FAQ

What is the HS code for Oil filter?

The HS code for an oil filter used in internal combustion engines is 8421.23.

Does this code include filters for hydraulic systems?

No, hydraulic fluid filters are typically classified under HS code 8421.29, as they are not specifically for the oil or petrol systems of internal combustion engines.
