HS Code 8431.42 – Machinery parts; bulldozer or angledozer blades
HS code 8431.42 is the 6-digit subheading for machinery parts, bulldozer or angledozer blades. It is used for straight blades, U-blades, S-blades, SU-blades and semi-U blades.
What HS 8431.42 covers
This HS code is specifically for blades used on bulldozers and angledozers, which are integral components for earth-moving, grading, and pushing materials in demanding environments. These blades are subject to extreme wear and tear in construction sites, mining operations, and land clearing projects, necessitating regular replacement to maintain equipment efficiency. The international trade in these parts is crucial for maintaining the operational readiness of heavy equipment fleets worldwide. Importers are typically construction companies, mining firms, and equipment service centers that require high-quality, durable replacement blades. Exporters are often specialized manufacturers, focusing on high-strength steel alloys, wear resistance, and precise engineering to ensure compatibility and optimal performance with various bulldozer and angledozer models.

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).
