Subheadings
Products classified under HTS 8547.90.00
PVC Insulated Flexible Electrical Conduit
Flexible electrical conduit tubing made of galvanized steel lined with PVC insulating material, used to protect wiring in industrial machinery. It falls under HTS 8547.90.00 as electrical conduit tubing of base metal lined with insulating material, distinct from unlined metal conduit or ceramic insulators. The metal core provides structure while the PVC lining ensures electrical insulation.
Galvanized Steel Insulated Conduit Joint Coupling
Couplings for joining insulated electrical conduits, featuring steel body lined with polyethylene insulator for secure, insulated connections in equipment wiring. Classified under HTS 8547.90.00 as joints for electrical conduit tubing of base metal lined with insulating material. The minor metal threads aid assembly while insulation prevents shorts.
Epoxy Insulated Motor Terminal Bushings
Bushings for electric motor terminals made of phenolic resin insulation with minor threaded metal inserts for mounting, preventing electrical arcing in appliances. HTS 8547.90.00 covers these as insulating fittings wholly of insulating material (minor metal for assembly) for electrical machines. They insulate high-current connections safely.
Silicone Rubber Insulated Cable Glands
Cable entry glands with aluminum base metal body lined/compressed with silicone rubber insulation for watertight, insulated wire entry into electrical enclosures. Under HTS 8547.90.00 as insulating fittings for appliances with minor metal for assembly. Provides strain relief and insulation in harsh environments.
Nylon-Lined Steel Electrical Conduit Elbow
90-degree elbow fittings for electrical conduit, steel tube lined with nylon insulator for directional wiring runs in equipment panels. HTS 8547.90.00 applies to such base metal conduit tubing and joints with insulating lining. Ensures bend protection without conductivity.
Ceramic-Filled Polymer Insulating Standoffs
Standoff insulators for mounting electrical components, polymer base with ceramic filler and minor brass threaded inserts, used in high-voltage appliances. Classified HTS 8547.90.00 for insulating fittings of electrical equipment with assembly metal. Provides creepage distance and support.
Brass Insulated Conduit Compression Connector
Compression-type connectors for liquid-tight insulated conduits, brass body with Santoprene thermoplastic lining for secure, insulated wire protection. HTS 8547.90.00 for base metal conduit joints lined with insulators. Common in washdown equipment.
Phenolic Insulated Appliance Strain Relief Bushings
Strain relief bushings for power cords entering appliances, phenolic insulation molded with steel retaining clips for cord grip and insulation. Under HTS 8547.90.00 as insulating fittings for electrical appliances. Prevents wire damage and shorts.
Polyethylene Lined EMT Conduit Adapter
Adapters converting EMT to insulated flexible conduit, steel with polyethylene insulating liner for hybrid wiring systems in machinery. HTS 8547.90.00 covers such lined base metal conduit joints. Bridges installation types safely.
Teflon-Coated Stainless Steel Conduit Nipple
Short conduit nipples of stainless steel with Teflon (PTFE) insulating coating for corrosive environments in chemical processing equipment. Classified HTS 8547.90.00 as base metal conduit tubing lined/ coated with insulating material. Chemical and electrical resistance.
Bakelite Insulating Switchboard Fittings
Mounting fittings for circuit breakers in switchboards, bakelite (phenolic) with threaded steel sockets for secure insulated assembly. HTS 8547.90.00 for insulating fittings of electrical equipment. Legacy material for high-reliability panels.
Rubber-Lined Flexible Metal Conduit
Helically wound steel flexible conduit lined with neoprene rubber for vibration-prone machinery wiring. Under HTS 8547.90.00 as electrical conduit tubing of base metal lined with insulating material. Superior flexibility and protection.
Urethane Insulated Panel Mount Bushing
Panel hole bushings of urethane insulation with brass eyelets for wire pass-through in control cabinets. HTS 8547.90.00 insulating fittings for electrical equipment. Grommet-style edge protection.
