U.S. imports of insulated winding wire, non-copper (nesoi) (HS 854419) totaled $4.3M in June 2026, traded with 30 countries.
Importers of Insulated Winding Wire, Non-Copper (NESOI) paid $1.0M in duties in June 2026 — an effective duty rate of 25% on $4.1M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Winding wire made from conductors other than copper — most commonly aluminum — falls under this residual heading, classified at the 10-digit level under a single line (8544190000). Aluminum winding wire is increasingly used in cost-sensitive motor and transformer applications where weight reduction is also a design factor. Mexico leads US import supply, with Germany and Turkey also notable sources, reflecting European specialty wire manufacturing capability. Importers should confirm that the wire is genuinely wound-wire construction rather than a stranded cable, as that distinction governs classification between Chapter 85 winding-wire headings and cable headings.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Heading 854419 covers insulated winding wire made from conductors other than copper — aluminum is the most commercially significant material. Other base metals used as winding conductors would also fall here if they meet the winding-wire construction criteria rather than qualifying as cables or other conductors.
The key distinction is end-use construction: winding wire is designed to be wound into coils for electromagnetic applications (motors, transformers, inductors) and is typically supplied on spools with a thin, flexible insulation coating. Stranded or multi-conductor cables designed for power transmission or wiring harnesses are classified elsewhere in heading 8544, even if made of aluminum.
