HS Code for Polypropylene staple fibers

Polypropylene staple fibers that have undergone mechanical processing are classified under HS code 5506.40. While also part of Chapter 55, heading 5506 is reserved for synthetic staple fibers that have been carded, combed, or otherwise processed for spinning. This distinction is critical in the textile industry, as carding and combing align the fibers into a parallel arrangement and remove impurities, preparing them for the subsequent spinning process into yarn. The classification 5506.40 specifically identifies polypropylene as the base polymer. This stage of production represents a higher level of value-add compared to the raw staple fibers found in heading 5503. These processed fibers are typically found in the form of sliver or top, ready for the spinning frame.

Products Included

• Carded polypropylene fiber sliver
• Combed polypropylene tops
• Processed PP fibers for yarn spinning
• Aligned polypropylene fibers for industrial textiles
• Gilled polypropylene fiber bundles

Common Misclassification

This product is often misclassified under 5503.40, which is the code for raw, unprocessed staple fibers. Customs authorities distinguish between the two based on whether the fibers show evidence of mechanical alignment (carding). It may also be confused with 5509.11, which is the actual spun yarn made from these fibers. Once the fibers are twisted into a continuous strand, they move from 5506 to 5509. Additionally, if the fibers are waste material that has been carded, they might still be viewed as waste under 5505 depending on the degree of recovery.

FAQ

What is the HS code for Polypropylene staple fibers?

For polypropylene staple fibers that have been carded or combed, the correct HS code is 5506.40.

Why is carding important for classification?

Carding is a specific industrial process that changes the HS heading from 5503 (unprocessed) to 5506 (processed), as it indicates the material is prepared for textile spinning.
