HS Code for Synthetic staple fibers

HS code 5506.90 identifies synthetic staple fibers that have undergone carding, combing, or other preparatory processes for spinning. This classification is distinct from heading 5503, which covers raw, unprocessed fibers. Chapter 55 governs man-made staple fibers, and heading 5506 specifically addresses those fibers that have been mechanically manipulated to align them or remove impurities, a necessary step before they can be spun into yarn. Subheading 5506.90 is the residual category for fibers other than nylon or other polyamides (5506.10), polyesters (5506.20), or acrylic and modacrylic (5506.30). The transition from a 5503 classification to a 5506 classification occurs the moment the fiber is subjected to carding or combing. This distinction is vital for customs purposes as processed fibers often carry different duty rates or regulatory requirements compared to raw staple fibers. The classification depends on the physical state of the fiber and its readiness for the spinning frame.

Common Misclassification

The most frequent misclassification is using 5503.90, which is for raw, unprocessed staple fibers. Another error involves 5506.10 or 5506.20 if the fibers are nylon or polyester, respectively. If the fibers are carded or combed but are of artificial origin (like rayon), they must be classified under heading 5507.00 instead.

FAQ

What is the HS code for Synthetic staple fibers?

The HS code for processed (carded or combed) synthetic staple fibers not specified elsewhere is 5506.90.

Why does carding change the HS code from 5503 to 5506?

Carding is a significant manufacturing step that prepares fibers for spinning; the HS system distinguishes between raw materials and semi-processed textile fibers.
