components of an After-Treatment System (“ATS”), a type of catalytic converter which filters pollutants from the exhaust gas emitted from a diesel engine
The tariff classification of components of an After-Treatment System from Mexico. The items under consideration are five components of an After-Treatment System (“ATS”), a type of catalytic converter which filters pollutants from the exhaust gas emitted from a diesel engine. You state that these parts are designed solely for use with the ATS, are integral to its operation and would serve no other practical purpose outside of that system. These components include: a Header Unit, a Diesel Exhaust Fluid (“DEF”) Tank, a DEF Tank with Header Unit, a DEF Suction Line and a DEF Pressure Line.
The DEF Suction Line consists of an inner polyamide-nylon flexible tube with an electrical heating coil wrapped around it which is encased in a corrugated plastic protective covering. It also includes electrically heated end fittings and a wire with an electrical connector. This product transports DEF from the DEF Tank (via the Header Unit) to an external DEF pump. The electrical heating coil and heated end fittings prevent the DEF from freezing during the delivery process.
The DEF Pressure Line is comprised of an inner tube made of EPDM rubber with an electrical heating coil wrapped around it that is enclosed in a protective corrugated plastic casing. This product also includes electrically heated end fittings and a wire with an electrical connector. The DEF Pressure Line transports DEF from the DEF pump to the Urea Dosing Unit while the electrical heating coil and heated end fittings ensure that the DEF does not freeze during transport.
