Product classification
HS code for TSNR: 4001.22
Rubber, technically specified natural rubber (TSNR), in primary forms or in plates, sheets or strip (excluding latex and smoked sheets).
Classification of TSNR under HS 4001.22
Technically Specified Natural Rubber (TSNR) is classified under HS code 4001.22. This classification is determined by the General Rules of Interpretation (GRI) of the Harmonized System, specifically GRI 1 and GRI 6. Chapter 40 covers rubber and articles thereof, and heading 4001 specifically addresses natural rubber in primary forms. TSNR is a specific form of natural rubber that has been processed into blocks and graded based on technical parameters such as dirt content, ash content, nitrogen content, volatile matter, and the Plasticity Retention Index (PRI), rather than the traditional visual grading used for Ribbed Smoked Sheets. This technical grading ensures a consistent quality that is essential for high-precision industrial applications, particularly in the automotive tire industry. The subheading 4001.22 is explicitly reserved for TSNR, distinguishing it from 4001.21 (smoked sheets) and 4001.29 (other forms like crepe rubber). The material must be in a primary form, such as blocks, or in plates, sheets, or strips to qualify under this heading. If the rubber were further worked or vulcanized, it would move to subsequent headings within Chapter 40. The classification is vital for international trade as TSNR is a primary raw material for tire manufacturing and industrial rubber products.

Codes often confused with 4001.22
Common mistake. TSNR is frequently confused with HS code 4001.21, which is reserved for Ribbed Smoked Sheets (RSS). While both are natural rubber, RSS is graded visually. It is also sometimes misclassified under 4001.10, which covers natural rubber latex, or 4002.11, which is for synthetic rubber like SBR. Accurate classification depends on whether the rubber is natural or synthetic and its specific processing method.
Top exporters and importers of HS 400122 (the code used for TSNR), 2025
In 2025, the largest exporter of HS 400122 (the code used for TSNR) in UN Comtrade data was Côte d'Ivoire, with 28% of world exports; the largest importer in UN Comtrade data was China, with 26% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 400122, not only TSNR.

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).
