📌 I. Product Definition & Classification: Do You Really Understand "Inner Tubes"?

Synthetic Rubber Inner Tubes (Butyl Rubber) are critical components for pneumatic tires, widely used in bicycles, motorcycles, and various automotive vehicles. In international trade, their classification depends heavily on the specific application (vehicle type) and physical form.

Key Distinctions:
- Rubber Products (Chapter 40): Classified by material if they are general-purpose or specific to certain tire types.
- Vehicle Parts (Chapter 87): Classified by end-use if they are specifically identified as parts of motorcycles or other vehicles.

⚠️ Critical Classification Point:
- If classified as a rubber product specifically for tires → Chapter 40 (e.g., 4013.90.50).
- If classified as a motorcycle part → Chapter 87 (e.g., 8714.10.00).
- If classified as a general vehicle accessory → Chapter 87 (e.g., 8714.99.80).
