HS Code for Nylon staple fibers

Nylon staple fibers that have undergone mechanical processing such as carding or combing are classified under HS code 5506.10. This code is part of Chapter 55, which manages man-made staple fibers. The transition from heading 5503 to 5506 occurs when the raw staple fibers are subjected to preparatory processes for spinning. Carding involves passing the fibers through a series of rollers with wire teeth to disentangle them and remove impurities, resulting in a continuous web or sliver. Combing is a further refinement step that aligns the fibers in a parallel fashion and removes shorter fibers. These processes are essential for creating high-quality yarn. Classification under 5506.10 indicates that the product is a semi-processed textile material, positioned between the raw fiber stage and the final yarn spinning stage. Customs authorities require this distinction because processed fibers often carry different duty rates and trade regulations compared to raw, unprocessed staple fibers.

Products Included

• Carded nylon staple fibers
• Combed polyamide staple fibers
• Nylon sliver for spinning
• Processed synthetic fibers for yarn production
• Polyamide tops (combed fibers)

Common Misclassification

The primary misclassification occurs with HS code 5503.19, which is for nylon staple fibers that have NOT been carded or combed. Importers must verify the processing state of the fiber to choose between these two. Another common mistake is classifying these fibers under 5509, which is the heading for yarn made of synthetic staple fibers. If the fibers have been spun into a continuous strand, they are yarn (5509); if they are still in the form of a sliver or loose processed mass, they remain in 5506.10.

FAQ

What is the HS code for processed nylon staple fibers?

The HS code for nylon staple fibers that have been carded, combed, or otherwise processed for spinning is 5506.10.

Why is carding important for HS classification?

Carding is a 'preparatory process' that changes the classification of the fiber from heading 5503 (raw) to 5506 (processed). It signifies that the material has moved further down the value chain toward becoming finished textile yarn.
