Product classification
HS code for Tire retreading machine: 8477.51
Machinery, for moulding or retreading pneumatic tyres or for moulding or otherwise forming inner tubes.
Classification of tire retreading machine under HS 8477.51
The classification of tire retreading machines under HS code 8477.51 is determined by the General Rules for the Interpretation (GRI) of the Harmonized System, specifically focusing on the function and material processed. Chapter 84 encompasses nuclear reactors, boilers, machinery, and mechanical appliances. Within this chapter, heading 8477 is dedicated to machinery for working rubber or plastics or for the manufacture of products from these materials, not specified or included elsewhere in the chapter. Subheading 8477.51 specifically identifies machinery for moulding or retreading pneumatic tyres or for moulding or otherwise forming inner tubes. This classification is precise because it addresses the specific industrial application of the machine—restoring the tread of used tires—rather than general rubber-working equipment. The machinery typically involves several stages, including buffing the old tread, applying new unvulcanized rubber, and curing the assembly under heat and pressure. Because the primary function is the specific act of retreading a pneumatic tire, it is excluded from more general headings and placed in this specific sub-category.
- Covers
- Tire buffing machines used to remove old tread
- Tire building machines for applying new rubber layers
- Curing presses specifically designed for tire retreading
- Autoclaves used in the cold retreading process
- Enveloping machines for retreading preparation
- Also under 8477.51
- VMI Tire Building Machines
- HF Group Tire Curing Presses
- Marangoni Retreading Equipment
- Kobe Steel Tire & Rubber Machinery
Codes often confused with 8477.51
Common mistake. Tire retreading machines are frequently confused with general rubber processing machinery under HS code 8477.80. While 8477.80 covers "other" machinery for working rubber, 8477.51 is a specific provision that takes precedence for retreading equipment. Additionally, some importers mistakenly use HS code 8479.89, which is a residual category for machines with individual functions not specified elsewhere. However, since the function of working rubber for tires is explicitly mentioned in 8477.51, the use of 8479 is incorrect according to GRI 1.
Top exporters and importers of HS 847751 (the code used for tire retreading machine), 2025
In 2025, the largest exporter of HS 847751 (the code used for tire retreading machine) 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).
