HS code for Winding wire: 8544.19
Insulated electric conductors, winding wire, (of other than copper).
Classification of winding wire under HS 8544.19
Winding wire, also known as magnet wire, is classified under HS code 8544.19 when the conductor is made of materials other than copper, such as aluminum or silver. Heading 8544 covers insulated wire, cable, and other insulated electric conductors, whether or not fitted with connectors. Subheading 8544.11 is reserved specifically for copper winding wire, while 8544.19 acts as the residual category for all other metallic conductors used for winding. Winding wire is characterized by a very thin, high-performance layer of insulation, typically an enamel, lacquer, or polymer film. This thin insulation allows for the maximum number of turns in a given space, which is essential for creating efficient electromagnetic coils in transformers, electric motors, solenoids, and inductors. The classification is based on the physical properties of the wire and its specific application in electrical winding. It is distinct from standard power cables because the insulation is not intended for heavy mechanical protection or high-voltage grounding but rather for electrical isolation between adjacent turns of a coil. Under GRI 1, the material composition of the conductor is the primary factor in choosing between 8544.11 and 8544.19. Furthermore, the wire must meet the definition of \"insulated\" even if the coating is nearly invisible to the naked eye. This code is essential for manufacturers of electrical components who utilize aluminum winding wire to reduce weight or cost compared to copper alternatives.

Codes often confused with 8544.19
Common mistake. The most common misclassification is 8544.11, which is exclusively for copper winding wire. Importers often fail to distinguish the base metal. Another error is 7605, which covers aluminum wire that is not insulated. If the wire has any form of electrical insulation, it must move from Chapter 76 to heading 8544. Additionally, it should not be confused with 8544.49, which is for other electric conductors not used for winding.
Top exporters and importers of HS 854419 (the code used for winding wire), 2025
In 2025, the largest exporter of HS 854419 (the code used for winding wire) in UN Comtrade data was China, with 40% of world exports; the largest importer in UN Comtrade data was the United Arab Emirates, with about 11% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 854419, not only winding wire.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about winding wire
What is the HS code for Winding wire?
The HS code for Winding wire is 854419 (Insulated electric conductors; winding wire, (of other than copper)). The HS code for insulated winding wire made of materials other than copper is 8544.19.
How do I classify Winding wire for customs?
Winding wire is classified under HS code 854419 — Insulated electric conductors; winding wire, (of other than copper). This is a 6-digit subheading level code.
Is aluminum winding wire classified differently than copper?
Yes, copper winding wire is classified under 8544.11, while aluminum and other non-copper winding wires fall under 8544.19.
Which countries are the top exporters of winding wire (HS 854419)?
In 2025, the top exporters of HS 854419 (the code used for winding wire) in UN Comtrade data were China ($570M, 40% of world exports), India ($126M) and the United States ($105M). World exports came to about $1.4B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of winding wire (HS 854419)?
