HS code 5516.31 is the 6-digit subheading for fabrics, woven, unbleached or bleached, containing less than 85% by weight of artificial staple fibres, mixed mainly or solely with wool or fine animal hair.

What HS 5516.31 covers
This HS code pertains to woven fabrics that are unbleached or bleached, containing less than 85% by weight of artificial staple fibres, mixed mainly or solely with wool or fine animal hair. These are foundational textile materials, often referred to as 'greige goods' or pre-treated fabrics, ready for further processing like dyeing or printing. The blend combines the luxurious feel and warmth of wool or fine animal hair (e.g., cashmere, alpaca) with the enhanced durability and stability of artificial staple fibers. They are highly sought after by high-end apparel manufacturers, tailors, and textile finishers for suiting, coats, and sophisticated garments. Major exporters are textile mills specializing in wool blends, while importers are typically garment factories and fashion houses looking for quality base materials.

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).
