HS code for Die base: 8480.20

Mould bases, for metal, metal carbides, glass, mineral materials, rubber or plastics.

Classification of die base under HS 8480.20

A die base, also referred to as a mould base, is classified under HS code 8480.20. Heading 8480 of the Harmonized System covers moulding boxes for metal foundry, mould bases, and various types of moulds for metal, metal carbides, glass, mineral materials, rubber, or plastics. The die base is the essential structural assembly that supports the mould cavity and provides the necessary alignment for the die components during the manufacturing process. According to the Explanatory Notes to the HS, mould bases are the plates and frames that house the internal parts of a mould. Because the die base is a specialized component designed specifically for the assembly of moulds, it is classified under the dedicated subheading 8480.20 rather than as general articles of steel or as parts of specific machinery. This classification applies to bases used in injection moulding, compression moulding, and die casting.

Codes often confused with 8480.20

Common mistake. Die bases are frequently misclassified under HS code 7326.90, which is a residual category for other articles of iron or steel. This occurs because the base often appears to be a simple assembly of steel plates. However, since it is a specific component of a mould assembly, heading 8480 takes precedence. It is also sometimes confused with HS code 8480.71 or 8480.79, which are the codes for the finished moulds for plastics or rubber, rather than just the base assembly.

Top exporters and importers of HS 848020 (the code used for die base), 2025

In 2025, the largest exporter of HS 848020 (the code used for die base) in UN Comtrade data was China, with 57% of world exports; the largest importer in UN Comtrade data was Malaysia, with 15% 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 that did not report are estimated from what other countries recorded trading with them. 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).
