HS Code 5506.30 – Fibres; synthetic staple fibres, acrylic or modacrylic, carded, combed or otherwise processed for spinning
HS code 5506.30 is the 6-digit subheading for fibres, synthetic staple fibres, acrylic or modacrylic, carded, combed or otherwise processed for spinning. It is used for acrylic staple fibre (carded), modacrylic staple fibre (combed), high-bulk acrylic fibre, flame-retardant modacrylic fibre and acrylic fibre for sweaters.
What HS 5506.30 covers
This category encompasses synthetic staple fibres made from acrylic or modacrylic polymers that have been prepared for spinning, typically through carding or combing. Acrylic fibres are known for their wool-like feel, warmth, and resistance to sunlight and chemicals, making them popular in knitwear and outdoor applications. Modacrylic fibres offer enhanced flame resistance and are often used in protective clothing and upholstery. These processed fibres are crucial intermediates for textile production. Importers are usually spinning mills, knitwear manufacturers, and producers of blankets, carpets, or faux fur. Exporters are specialized chemical companies and fibre manufacturers. Important trade considerations include fibre denier, staple length, lustre, and specific properties like flame retardancy or softness, which dictate their end-use. The market for these fibres is influenced by fashion trends, demand for synthetic alternatives to wool, and safety regulations for flame-resistant materials.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
