Chapter 8113 — Customs Tariff Headings
Products classified under Tariff item 81.13
Cermet Armor Tiles
Lightweight ballistic armor tiles manufactured from a boron carbide-metal matrix cermet composite. These tiles are designed for use in protective armor systems and qualify as cermets under tariff item 8113.00.00 because they consist of a microscopic heterogeneous combination of a metallic and ceramic component.
8113.00.00Cermet Bearing Bushings
Self-lubricating bearing bushings made from aluminum oxide-titanium cermets, designed for high-temperature bearing applications. These bushings are classified as cermet articles under 8113.00.00 because they are formed from a sintered metal-ceramic composite with a hard, low-friction structure.
8113.00.00Cermet Extrusion Dies
Long-life extrusion dies manufactured from tantalum carbide cermets, used for wire drawing applications. These dies are classified under 8113.00.00 as cermet articles because they are made from a sintered composite of ceramic carbide and metallic binder, providing superior deformation resistance.
8113.00.00Cermet Heat Exchanger Plates
Corrosion-resistant heat exchanger plates made from oxide-metal cermets, designed for compact heat exchangers. These plates are classified as cermet articles under 8113.00.00 due to their sintered ceramic-metal composite structure, which provides enhanced corrosion resistance.
8113.00.00Cermet Nozzle for Injection Molding
High-wear nozzles made from chrome carbide cermets, used in plastic injection molding machines. These nozzles are classified under 8113.00.00 as cermet articles because they are formed from a ceramic-metal composite that offers thermal shock resistance and wear resistance.
8113.00.00Cermet Powder for Additive Manufacturing
Fine spherical powder of tungsten carbide-cobalt cermet, prepared for additive manufacturing of wear parts. This powder is classified under 8113.00.00 as a cermet product because it consists of a sintered metal carbide composite, and the term cermets includes sintered metal carbides per Section XV Note 4.
8113.00.00Cermet Scrap from Tool Manufacturing
Waste and scrap cermet material generated from grinding tungsten carbide inserts during production. This material is explicitly covered under 8113.00.00, which includes waste and scrap of cermets, and is not usable as a finished product.
8113.00.00Cermet Seal Rings
Mechanical seal faces made from silicon carbide-metal cermets, used in pumps for chemical resistance. These seal rings are classified as cermet articles under 8113.00.00 because they are formed from a sintered ceramic-metal composite providing chemical resistance.
8113.00.00Cermet Valve Seats
Durable valve seat inserts made from nickel-tungsten cermet, designed for engine applications. These valve seats are classified under 8113.00.00 as cermet articles because they are made from a sintered ceramic-metal composite offering superior erosion resistance.
8113.00.00Cermet Wear-Resistant Plate
Hard-wearing plates composed of titanium carbide cermets bonded with cobalt, used in industrial chutes and hoppers. These plates are classified as cermet articles under 8113.00.00 due to their sintered metal-ceramic composition, which provides wear resistance.
8113.00.00Cermet Welding Electrode
Composite welding electrodes with a cermet core, used for hardfacing applications to provide corrosion-resistant deposits. These electrodes are classified under 8113.00.00 as cermet articles because they contain a ceramic-metal matrix for wear-resistant surfaces.
8113.00.00Recycled Cermet Tool Blanks
Sintered blanks made from recycled cermet scrap, intended for custom tool manufacturing. These blanks are classified under 8113.00.00 as cermet articles because they are formed from sintered metal carbides, and the heading includes waste-derived articles.
8113.00.00Titanium Cermet Wire for Wear Coating
Continuous wire of titanium carbide cermet, used for thermal spray wear-resistant coatings. This wire is classified under 8113.00.00 as a cermet article because it is made from a ceramic-metal composite in wire form.
8113.00.00Tungsten Carbide Cutting Insert
Precision-engineered cutting inserts made from tungsten carbide cermet, used in machining tools for cutting metals. These inserts are classified under 8113.00.00 as cermet articles because they have a composite structure of ceramic and metallic components.
8113.00.00Waste Cermet Grinding Sludge
Sludge from grinding cermet tools, containing recoverable carbide particles. This material is classified under 8113.00.00 as waste and scrap because it is not usable as a finished product and contains cermet particles.
