Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If coated with zinc (galvanized)
Even thin zinc coating moves fine wire to plated/coated subchapter.
If insulated with plastics for electrical use
Insulated wire/cable classified in Chapter 85 as electrical conductors.
If drawn and sold as interchangeable tool blades
Wire formed into knife blades or tools goes to Chapter 82 interchangeable tools.

Import Tips & Compliance
• Fine wire requires precise diameter certification; tolerances tighter for sub-1mm sizes
• Spool packaging standard; loose wire risks damage claims denial due to rust rules
• Distinguish from alloy fine wire (e.g
• piano wire) which uses Chapter 72 alloy headings
