Product classification
HS code for Tin wire: 8003.00
Tin, bars, rods, profiles and wire.
Classification of tin wire under HS 8003.00
Tin wire is classified under HS code 8003.00, which encompasses tin bars, rods, profiles, and wire. This classification is governed by the General Rules for the Interpretation of the Harmonized System (GRI), specifically focusing on the material composition and the physical form of the product. Chapter 80 is dedicated to tin and articles thereof. According to Note 1(c) to Chapter 80, wire is defined as rolled, extruded, or drawn products, in coils, which have a uniform solid cross-section along their whole length in the shape of circles, ovals, rectangles, squares, equilateral triangles, or regular convex polygons. For a product to be classified here, the tin content must predominate by weight over any other single element. The wire must be solid and not contain a core of flux material, as that would change the classification to a different chapter entirely.
- Covers
- Pure tin wire for industrial applications
- Tin alloy wire (where tin is the main component)
- Drawn tin wire in coils
- Tin-based fuse wire
- Also under 8003.00
- Kester solder wire
- Alpha Assembly Solutions solder bars
- Multicore solder
- Indium Corporation tin wire
- Stannol solder bars
Codes often confused with 8003.00
Common mistake. The most common misclassification for tin wire is HS code 8311.30, which covers cored wire of base metal for soldering. If the tin wire contains a core of rosin or other flux, it is no longer classified as a simple metal wire in Chapter 80 but as a prepared soldering material in Chapter 83. Another common error is using HS code 8007.00, which is a residual category for other articles of tin. However, because 8003.00 specifically mentions 'wire,' it takes precedence over the general 'articles' heading according to GRI 3(a).
Top exporters and importers of HS 800300 (the code used for tin wire), 2025
In 2025, the largest exporter of HS 800300 (the code used for tin wire) in UN Comtrade data was China, with 14% of world exports; the largest importer in UN Comtrade data was China, with 14% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
