Product classification
HS code for Inner tubes: 4013.90
Rubber, inner tubes, n.e.c. in heading no. 4013.
Classification of inner tubes under HS 4013.90
Inner tubes are classified under HS code 4013.90 based on their material composition and functional design. Chapter 40 of the Harmonized System covers rubber and articles thereof. Heading 4013 specifically addresses inner tubes made of vulcanized rubber. While subheadings 4013.10 and 4013.20 are reserved for tubes used on motor cars, buses, lorries, and bicycles respectively, subheading 4013.90 serves as the residual category for all other types of inner tubes. This includes tubes for motorcycles, agricultural machinery, aircraft, and industrial vehicles. The classification is driven by General Interpretative Rule 1, which dictates that classification is determined by the terms of the headings and any relative section or chapter notes. Since these products are finished articles of vulcanized rubber designed to retain air under pressure within a tire casing, they are excluded from general rubber headings and placed into this specific commodity code. The material must be vulcanized rubber; tubes made of plastics would fall under Chapter 39.

Codes often confused with 4013.90
Common mistake. Inner tubes are often misclassified under 4013.10 (motor cars/buses) or 4013.20 (bicycles) if the specific vehicle type is not identified. They are also sometimes incorrectly placed in 4011, which is the heading for outer pneumatic tires. It is critical to distinguish the tube from the tire casing. Furthermore, if the tube is made of synthetic materials other than vulcanized rubber, it may fall under 3917.

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).
