Product classification
HS code for Wire strand: 7312.10
Iron or steel, stranded wire, ropes and cables, not electrically insulated.
Classification of wire strand under HS 7312.10
HS code 7312.10 is used for wire strand, which consists of several individual wires twisted together to form a single strand. This code covers iron or steel stranded wire, ropes, and cables that have not been electrically insulated. The classification is based on the manufacturing state of the product; it is considered a primary form of wire product rather than a finished article like a sling. Stranded wire is the fundamental component used to create wire rope. This heading excludes single wires (which are found in heading 7217) and focuses on the "stranded" or "plaited" nature of the product. It is important to note that this code applies regardless of whether the strand is intended for structural use, fencing, or further processing into more complex rope structures. The material must be iron or steel; strands made of copper or aluminum are classified in their respective chapters (74 and 76). The absence of insulation is a critical requirement, as any electrical insulation would shift the classification to Chapter 85.

Codes often confused with 7312.10
Common mistake. Wire strand is often misclassified under 7217.10, which is only for single, non-stranded wire. It is also confused with 7312.90, which is for finished articles like slings. Another common mistake is classifying it under 8544.49 if the importer assumes all "cables" belong in the electrical chapter, but 8544 only applies if the cable is insulated for electricity.

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).
