HTS Chapter 40 covers rubber and many rubber products. It includes natural rubber, synthetic rubber, unvulcanized or vulcanized rubber, tires, tubes, belts, hoses, gloves, medical or hygienic articles, and other finished articles made primarily of rubber. The correct classification depends on the product’s material, physical form, manufacturing stage, and intended use.
The HTS is organized from broad to specific: chapter 40 identifies the rubber chapter; a four-digit heading, such as 4010 for conveyor or transmission belts, narrows the product type; additional digits identify the subheading and its characteristics. The complete US classification is generally a 10-digit HTS code. Start with the product’s composition and condition, then compare the relevant heading and subheading descriptions, legal notes, and exclusions. Confirm the final code using current official HTSUS data or a qualified customs professional.
What to check
- Check whether the item is natural rubber, synthetic rubber, compounded rubber, unvulcanized rubber, vulcanized rubber, or hard rubber.
- Identify the product’s form and function, such as a raw sheet, hose, belt, tire, glove, medical article, or other finished article; do not classify by marketing name alone.
- Review the chapter and section notes for exclusions, including products that may be classified in another chapter because of their composition, construction, or principal use.
- Confirm relevant technical details such as textile or metal reinforcement, fittings, tire condition, and whether the article is designed for a specific machine or use.
- After selecting the base HTSUS code, check current Chapter 99 provisions and other applicable measures, and verify any documentation or origin requirements before entry.
How to use this chapter
A chapter is the first classification level, not a duty rate. Choose the heading that describes the product, narrow by material, construction, use, or other legal distinctions, and verify the final line against the official HTS notes.
