Mountain Bike Inner Tubes

🚲 2. HS Code Classification & Tariff Guide for Mountain Bike Inner Tubes

(2026 Latest Tariff Analysis | Expert Customs Clearance Strategy)

📌 1. Product Definition & Classification Logic

Inner Tubes for Mountain Bikes are essential pneumatic components used inside bicycle tires to maintain air pressure. They are typically made of butyl rubber or latex, with an integrated valve (Schrader or Presta).

In international trade, these products are not classified under "Bicycles" (Chapter 87). Instead, they are classified as "Parts of general use" made of rubber.

Correct HS Code:

4009.41 – Vibration-damped inner tubes, of rubber, with integral valve, of a kind used for motors, or parts thereof, for bicycles.

Note: Specifically, 4009.41.00 is commonly used globally for bicycle inner tubes with integral valves.

🌐 2. Key Distinctions & Common Errors

⚠️ Critical Point:
If the valve is separate and sold without the tube, the tube is 4009.10.00.
If the valve is integral (molded into the tube), the tube is 4009.41.00.
Most mountain bike inner tubes have integral valves → Use 4009.41.00.
