U.S. imports of insulated copper winding wire (HS 854411) totaled $92.0M in July 2026, traded with 55 countries.
Importers of Insulated Copper Winding Wire paid $6.2M in duties in July 2026 — an effective duty rate of 18% on $34.3M in dutiable value, based on actual customs collections rather than the published tariff schedule. Insulated Copper Winding Wire imports of $92.0M in July 2026 ran 24% above the year-to-date monthly average of $74.0M.
Last updated: July 2026 dataCopper magnet wire — the insulated winding wire used in motors, transformers, solenoids, and inductors — is subdivided in the US schedule by conductor gauge: wire of 33 AWG (0.18 mm) and finer (8544110020), wire in the 22–33 AWG range (8544110030), and all other copper winding wire (8544110050). Gauge-based classification directly affects duty treatment and is a frequent point of CBP inquiry. Mexico is the primary import source, with China and India also supplying significant volumes; USMCA origin rules make Mexican-origin wire a common choice for North American motor and transformer manufacturers.

Classification among the three 10-digit lines under 854411 turns on the wire's AWG gauge: 33 AWG and finer goes to 8544110020, wire between 22 AWG and 33 AWG to 8544110030, and all other copper winding wire to 8544110050. Importers should have mill certifications or technical data sheets confirming conductor diameter available at entry.
Within heading 854411, the US schedule does not subdivide by insulation type (enamel, polyurethane, polyester-imide, etc.) — gauge is the controlling variable. However, if the wire's insulation or construction causes it to function as a cable rather than a winding wire, reclassification to another heading in Chapter 85 may be appropriate.
