HS v2022 Code: 842132

About machinery; catalytic converters or particulate filters, whether or not combined, for purifying or filtering exhaust gases from internal combustion engines

HS code 842132 covers machinery, specifically catalytic converters and particulate filters, used for purifying or filtering exhaust gases from internal combustion engines. This industry plays a crucial role in the automotive sector, helping to reduce harmful emissions and improve air quality. As environmental regulations become increasingly stringent, the demand for these technologies has grown significantly, making this a key segment within the broader import/export landscape.

Production process

The production of catalytic converters and particulate filters involves several key steps. First, the core structure, typically made of ceramic or metal, is manufactured. This is then coated with precious metals such as platinum, palladium, or rhodium, which act as the catalytic agents. The coated structure is then enclosed in a metal casing, often made of stainless steel, to create the final converter or filter unit. Advanced production techniques, including precise coating processes and quality control measures, are essential to ensure the effective performance of these emissions-control devices.

Production inputs

The main inputs required for the production of HS code 842132 items include the core ceramic or metal structures, precious metal catalysts, and the metal casings. Additionally, specialized machinery and equipment, such as coating chambers and quality testing apparatus, are necessary for the manufacturing process. The availability and cost of these raw materials and production resources can significantly impact the industry's competitiveness and profitability.

Production outputs

The primary output of HS code 842132 is catalytic converters and particulate filters for internal combustion engines. These emissions-control devices are essential components in the automotive industry, as they help to reduce the release of harmful pollutants such as carbon monoxide, hydrocarbons, and nitrogen oxides. The output of this industry is consumed by 870323 Motor cars and other motor vehicles principally designed for the transport of persons, including station wagons and racing cars and 870324 Motor cars and other motor vehicles principally designed for the transport of persons, including station wagons and racing cars manufacturers, as well as the broader automotive aftermarket.
