Product classification
HS code for Technically specified natural rubber: 4001.22
Rubber, technically specified natural rubber (TSNR), in primary forms or in plates, sheets or strip (excluding latex and smoked sheets).
Classification of technically specified natural rubber under HS 4001.22
Technically Specified Natural Rubber (TSNR) is classified under HS code 4001.22. This classification is determined by the General Rules for the Interpretation (GRI) of the Harmonized System, specifically falling under Chapter 40, which covers rubber and articles thereof. TSNR is natural rubber that has been processed and graded based on technical parameters such as dirt content, ash content, nitrogen content, and volatile matter, rather than the traditional visual grading used for smoked sheets. The classification 4001.22 specifically identifies natural rubber in primary forms or in plates, sheets, or strips that has undergone this technical specification process. This ensures that the material meets industrial standards for consistency and quality, which is critical for manufacturing tires and other high-performance rubber goods. The classification excludes natural rubber latex (4001.10) and smoked sheets (4001.21), as these have distinct physical forms and processing methods.

Codes often confused with 4001.22
Common mistake. TSNR is frequently misclassified with HS code 4001.21, which is reserved for smoked sheets. While both are natural rubber, smoked sheets are graded visually (e.g., RSS1, RSS3) and have not undergone the specific technical testing required for 4001.22. Another common error is using HS code 4002, which is strictly for synthetic rubber produced from petroleum-based feedstocks. Importers must also distinguish TSNR from 4001.10, which covers natural rubber latex in liquid form, even if that latex is technically specified.

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).
