Products classified under HTS 8544.11.00.20
Enameled 34 AWG Copper Magnet Wire
Ultra-fine enameled copper winding wire with a diameter of 0.16 mm (34 AWG), insulated with polyurethane enamel for high-temperature applications. Classified under HTS 8544.11.0020 because it is copper winding wire finer than 33 AWG (0.18 mm). Used primarily in micro-motors, transformers, and precision inductors.
Polyurethane Insulated 36 AWG Copper Winding Wire
Fine 0.127 mm (36 AWG) copper wire with polyurethane insulation, solderable coating for electronics manufacturing. Meets HTS 8544.11.0020 criteria as copper winding wire finer than 33 AWG, ideal for fine coil windings in relays and sensors.
High-Temperature 35 AWG Enameled Copper Coil Wire
0.17 mm (35 AWG) copper wire with Class 155°C polyester-imide enamel insulation for demanding thermal environments. HTS 8544.11.0020 applies due to copper composition and diameter finer than 33 AWG specification for winding applications in solenoids.
Solderable 37 AWG Copper Magnet Wire Spool
Ultra-fine 0.112 mm (37 AWG) solderable polyurethane-nylon copper winding wire on 3-inch spools. Specifically designed for high-density voice coils and micro-speaker production, qualifying under HTS 8544.11.0020 for fine copper winding wire.
Precision 38 AWG Triple-Insulated Copper Wire
0.101 mm (38 AWG) copper wire with triple-layer insulation (base coat, bond coat, overcoat) for transformer bobbinless windings. HTS 8544.11.0020 classification due to ultra-fine diameter copper winding wire characteristics.
Micro-Motor 34 AWG Enameled Copper Winding Wire
High-strength 0.16 mm (34 AWG) copper wire with modified enamel for vibration-resistant micro-motor stators. Falls under HTS 8544.11.0020 as fine-diameter copper specifically for winding applications in precision electric motors.
Voice Coil 36 AWG Solderable Magnet Wire
Audio-grade 0.127 mm (36 AWG) copper magnet wire with heavy solderable build for headphone and speaker voice coils. HTS 8544.11.0020 due to fine gauge copper winding wire construction meeting exact diameter specification.
Sensor Coil 39 AWG Copper Enamel Wire
Ultra-micro 0.09 mm (39 AWG) enamel insulated copper wire for precision position sensors and LVDT coils. Classifies under HTS 8544.11.0020 as the finest category of copper winding wire for instrumentation applications.
