HS Code for DPF filter

Diesel Particulate Filters (DPF) are classified under HS code 842132. This classification falls within Chapter 84, which encompasses nuclear reactors, boilers, machinery, and mechanical appliances. Heading 8421 specifically covers centrifuges and filtering or purifying machinery and apparatus for liquids or gases. The sub-heading 842132 is a specific provision for catalytic converters or particulate filters, whether or not combined, designed for purifying or filtering exhaust gases from internal combustion engines. The classification is determined by the primary function of the device, which is the mechanical and chemical removal of soot and particulate matter from engine emissions. As an essential component for environmental compliance in modern diesel engines, the DPF is recognized as a specialized filtering apparatus rather than a general engine part.

Products Included

• Ceramic wall-flow particulate filters
• Silicon carbide DPF units
• Sintered metal fiber filters for exhaust
• Combined DPF and Catalytic Converter units
• Retrofit diesel soot filters

Common Misclassification

A common misclassification for DPF filters is HS code 842139, which is the residual category for other gas filtering or purifying machinery. However, because 842132 specifically mentions particulate filters for exhaust gases, it must be used according to the principle of specificity. Another frequent error is classifying these filters under 870892, which covers parts and accessories of motor vehicles, specifically silencers (mufflers) and exhaust pipes. Under the General Rules of Interpretation (GRI 1), a product that is specifically described in a heading of Chapter 84 (filtering machinery) is excluded from the general parts headings of Chapter 87.
