HS Code 8477.51 – Machinery; for moulding or retreading pneumatic tyres or for moulding or otherwise forming inner tubes
HS code 8477.51 is the 6-digit subheading for machinery, for moulding or retreading pneumatic tyres or for moulding or otherwise forming inner tubes. It is used for tire curing presses, tire building machines, inner tube moulding machines, tire retreading presses and tire vulcanizers.
What HS 8477.51 covers
This highly specialized HS code is dedicated to machinery for moulding or retreading pneumatic tyres, or for moulding or otherwise forming inner tubes. These machines are critical components in the global tire manufacturing and retreading industries. They perform precise operations like tire building, curing (vulcanization), and applying new tread to used tires. International trade in this equipment is directly linked to the automotive sector's demand for new tires and the growing emphasis on sustainability through tire retreading. Major importers are countries with large automotive manufacturing bases or significant transportation industries. Exporters are typically specialized engineering firms from nations with advanced industrial machinery production capabilities, focusing on safety standards and production efficiency.

Codes often confused with 8477.51
Common mistake. This code is quite specific; confusion might arise with 847759 (other moulding/forming for rubber) if the specific application to tires/inner tubes is overlooked, or general rubber processing machinery under 847780.
Top exporters and importers of HS code 847751, 2025
In 2025, the largest exporter of HS code 847751 in UN Comtrade data was China, with 52% of world exports; the largest importer in UN Comtrade data was Cambodia, with about 23% 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).
