HS code for Viscose staple fiber: 5504.10
Fibres, artificial staple fibres, of viscose, not carded, combed or otherwise processed for spinning.
Classification of viscose staple fiber under HS 5504.10
Viscose staple fiber is classified under HS code 5504.10. This code is part of Chapter 55, which covers man-made staple fibers. Unlike Chapter 54, which deals with continuous filaments, Chapter 55 is for fibers that have been cut into specific lengths (staple) or are otherwise discontinuous. Heading 5504 specifically covers artificial staple fibers that have not been carded, combed, or otherwise processed for spinning. Viscose rayon is the most common type of artificial fiber, produced from wood pulp or other cellulose sources. The classification 5504.10 is used for the raw, bulk fiber before it undergoes mechanical alignment (carding/combing) to become a "sliver" or "roving." This material is typically sold in large bales to spinning mills. It is essential to distinguish these from synthetic staple fibers (like polyester or acrylic), which are classified under 5503. The production process involves extruding a viscose solution into an acid bath, where it regenerates into cellulose filaments, which are then bundled and cut to the desired staple length. These fibers are highly valued for their biodegradability and comfort, making them a popular choice for blending with cotton or wool in the apparel industry.

Codes often confused with 5504.10
Common mistake. This code is often confused with 5503.20 (polyester staple fibers) or other synthetic fibers. It is also confused with 5507.00, which covers artificial staple fibers that have already been carded or combed. If the fiber is continuous filament, it belongs in Chapter 54.
Top exporters and importers of HS 550410 (the code used for viscose staple fiber), 2025

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
