Automotive & Vehicles
View full HS code details

Carbon black rubber compound is classified under HS code 4005.10. This classification is based on the product being unvulcanised rubber that has been mixed or 'compounded' with specific reinforcing agents. Chapter 40 covers rubber and articles thereof, and heading 4005 is dedicated to compounded rubber, unvulcanised, in primary forms or in plates, sheets, or strip. Subheading 4005.10 specifically identifies rubber compounded with carbon black or silica. Carbon black is added to raw rubber to improve its mechanical properties, such as tensile strength and abrasion resistance, making it a critical intermediate product for the automotive and industrial sectors. To qualify for this code, the material must remain in an unvulcanised state; once it is vulcanized, it is classified elsewhere in Chapter 40 depending on its final form.

Products Included

  • Unvulcanised rubber masterbatches containing carbon black
  • Compounded rubber sheets for tire manufacturing
  • Unvulcanised rubber strips with silica or carbon black reinforcement
  • Primary form rubber compounds for industrial seals
  • Natural or synthetic rubber mixed with carbon black in bulk

Common Misclassification

This product is often misclassified under HS code 2803.00, which is the code for pure carbon black. However, once the carbon black is mixed with rubber, it must be classified in Chapter 40. Another common error is using 4002, which covers synthetic rubber; however, 4002 is for rubber that has not yet been compounded with fillers like carbon black. Finally, if the rubber is already vulcanized, it should be classified under 4008 (plates/sheets) or 4016 (other articles).
