HS Code for Carbon fibers

Carbon fibers in their primary forms, such as tow, yarn, or rovings, are classified under HS code 6815.11. This code was established to provide a specific category for carbon fibers for non-electrical uses within Chapter 68. Previously, these items might have been classified under more general subheadings, but the increasing importance of carbon fiber in global trade led to the creation of 6815.11. These fibers are produced through the carbonization of organic polymers like polyacrylonitrile (PAN) or rayon. The classification applies to the fibers themselves before they are woven into fabrics or molded into finished components. It is important to note that if the fibers are intended for electrical applications, they might move to Chapter 85. The classification process involves verifying that the fibers are not yet converted into a fabric (6815.12) or a finished article (6815.13). Carbon fibers are valued for their high strength-to-weight ratio and thermal resistance. In the context of international trade, 6815.11 covers the raw material stage, including continuous filament tow and chopped fibers, provided they have not been further processed into a textile or a specific component.

Products Included

• Carbon fiber tow
• Carbon fiber yarn
• Carbon fiber rovings
• Chopped carbon fibers
• Carbon fiber filaments

Common Misclassification

Raw carbon fibers are often misclassified as synthetic staple fibers under 5503 or synthetic filament yarn under 5402. However, because they are mineral-based (carbon), they must stay in Chapter 68. They are also confused with carbon fabrics (6815.12).

FAQ

What is the HS code for Carbon fibers?

The HS code for raw carbon fibers (tow, yarn, or rovings) for non-electrical use is 6815.11.

Is PAN-based fiber classified here?

Yes, once the precursor (like PAN) has been carbonized into carbon fiber, it is classified under 6815.11.
