HS Code 5506.10 – Fibres; synthetic staple fibres, of nylon or other polyamides, carded, combed or otherwise processed for spinning
HS code 5506.10 is the 6-digit subheading for fibres, synthetic staple fibres, of nylon or other polyamides, carded, combed or otherwise processed for spinning. It is used for nylon 6 staple fibre (carded), nylon 6,6 staple fibre (combed), polyamide 11 staple fibre (processed), recycled nylon staple fibre (prepared) and nylon carpet fibre (carded).
What HS 5506.10 covers
This category covers synthetic staple fibres made from nylon or other polyamides that have undergone initial processing steps like carding, combing, or other preparations to make them ready for spinning into yarn. These fibres are crucial intermediates in the textile supply chain, valued for their strength, elasticity, abrasion resistance, and durability. Importers are typically spinning mills, yarn manufacturers, and producers of technical textiles or apparel fabrics. Exporters are major chemical companies and fibre manufacturers specializing in polyamide production. Key aspects for trade include the specific type of polyamide (e.g., Nylon 6, Nylon 6,6), fibre denier, staple length, and whether it's bright, semi-dull, or dull, as these properties dictate its suitability for various applications, from hosiery and activewear to carpets and industrial ropes. The market is driven by demand for high-performance textiles and a growing focus on sustainable polyamide options.

Codes often confused with 5506.10
Common mistake. This code can be confused with 550311 (unprocessed nylon staple fibres) or other processed synthetic fibres like 550620 (polyester), but the distinction is the specific fibre type (nylon/polyamide) and the "carded, combed or otherwise processed" stage.

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).
