Products classified under HTS 7408.19.00.30
0.5mm Refined Copper Magnet Wire
Enamel-insulated refined copper wire with a 0.5mm diameter, used in electric motors and transformers. Classified under HTS 7408.19.0030 because it is refined copper wire with a maximum cross-sectional dimension of 3mm or less, excluding copper-zinc base alloys. The thin gauge makes it ideal for compact windings in small appliances.
1.0mm Pure Copper Winding Wire
Unalloyed refined copper wire, 1mm diameter, coated with thin polyurethane insulation for transformer windings. Falls under HTS 7408.19.0030 as refined copper wire ≤3mm cross-section, distinguished from alloy wires by its high purity electrolytic copper base. Commonly used in power distribution equipment.
0.8mm Enamelled Refined Copper Wire
Fine 0.8mm refined copper wire with solderable enamel coating for solenoids and relays. Classified in HTS 7408.19.0030 as other refined copper wire ≤3mm, prior to Chapter 85 insulation provisions. Essential for precision electromagnetic devices.
2.5mm Electrolytic Tough Pitch Copper Wire
ETP refined copper wire with 2.5mm diameter, bare or lightly coated, for busbar connections and grounding. HTS 7408.19.0030 applies to refined copper wire with cross-section ≤3mm, excluding specific copper alloy definitions in subheading notes. High conductivity suits electrical infrastructure.
1.8mm Oxygen-Free Copper Wire
High-purity oxygen-free refined copper wire, 1.8mm gauge, for audio equipment and RF applications. HTS 7408.19.0030 covers refined copper wire ≤3mm excluding defined alloys, with OF copper meeting >99.95% purity standards. Minimizes signal loss in high-frequency uses.
0.3mm Bare Refined Copper Fine Wire
Ultra-fine bare refined copper wire, 0.3mm diameter, for jewelry making and arts/crafts. Under HTS 7408.19.0030 as other refined copper wire ≤3mm, not alloyed per chapter notes. Dead-soft temper enables intricate bending.
2.0mm Annealed Refined Copper Wire
Soft-annealed refined copper wire 2.0mm thick for automotive harnesses and welding. HTS 7408.19.0030 for refined copper wire with max dimension ≤3mm, post-drawing but pre-insulation. Excellent ductility for forming applications.
1.2mm Phosphorized Refined Copper Wire
Refined copper wire with trace phosphor deoxidizer, 1.2mm diameter for plumbing fittings. Still classifies under HTS 7408.19.0030 as refined (not alloy per notes), ≤3mm cross-section. Enhanced strength for brazed joints.
0.6mm High-Conductivity Copper Wire
99.99% pure refined copper wire, 0.6mm, for medical device sensors. HTS 7408.19.0030 applies to non-alloy refined wire ≤3mm. Superior purity reduces resistance in biomedical applications.
2.9mm Refined Copper Bus Wire
Rectangular refined copper bus wire, max dimension 2.9mm, for circuit boards. Fits HTS 7408.19.0030 as refined ≤3mm wire. Flat profile optimizes space in electronics.
