About heading 8544

Insulated (including enameled or anodized) wire, cable (including coaxial cable) and other insulated electric conductors, whether or not fitted with connectors; optical fiber cables, made up of individually sheathed fibers, whether or not assembled with electric conductors or fitted with connectors

Heading 8544 covers insulated wire, cable and other insulated electric conductors, whether or not fitted with connectors, plus optical fiber cables made of individually sheathed fibers. It is split first by type: winding wire, coaxial cable, ignition wiring sets, other conductors at or below 1,000 V, other conductors above 1,000 V, and optical fiber cables. The 1,000 V group is further split by whether connectors are fitted, then by voltage, use and material.
