Product classification
HS code for Rubber thread: 4007.00
Rubber, vulcanised, thread and cord.
Classification of rubber thread under HS 4007.00
HS code 4007.00 is designated for vulcanized rubber thread and cord. This classification is specific to rubber that has undergone the vulcanization process, which provides the elasticity and thermal stability required for textile and industrial applications. These products are widely used in the garment industry to create elasticated waistbands, cuffs, and specialized fabrics. The code covers both \"bare\" rubber thread and cord. However, there is a critical technical threshold: the cross-sectional dimension. If the rubber cord has a cross-section exceeding 5mm, it is no longer considered thread or cord and is instead classified as rods or profiles under heading 4008. The material must be vulcanized rubber; unvulcanized rubber thread would fall under 4006. This code is essential for manufacturers of elastic textiles, as it distinguishes raw rubber components from finished elastic yarns that may contain textile coverings.

Codes often confused with 4007.00
Common mistake. The most frequent misclassification involves rubber thread that has been covered or braided with textile fibers. Once the rubber thread is covered with textile, it is classified under HS code 5604.10 (Rubber thread and cord, textile covered). Another common error is confusing rubber thread with synthetic elastomeric yarns like spandex or Lycra. These synthetic materials are classified in Section XI (Textiles), specifically under headings like 5402 or 5404, depending on their form. Finally, any rubber cord thicker than 5mm must be moved to 4008.29.

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).
