HS Code 5503.19 – Fibres; synthetic staple fibres, of nylon or other polyamides other than aramids, not carded, combed or otherwise processed for spinning
HS code 5503.19 is the 6-digit subheading for fibres, synthetic staple fibres, of nylon or other polyamides other than aramids, not carded, combed or otherwise processed for spinning. It is used for nylon 6 staple fiber, nylon 6,6 staple fiber, polyamide staple fiber for carpets, polyamide staple fiber for nonwovens and recycled nylon staple fiber.
What HS 5503.19 covers
This HS code covers synthetic staple fibers made from nylon or other polyamides, excluding the specialized aramid types. These fibers are traded in their raw, unprocessed form, ready for further textile processing. Nylon staple fibers are highly valued in international trade for their excellent strength, elasticity, abrasion resistance, and dyeability, making them versatile for a wide range of applications. Major importers are countries with robust textile, carpet, and nonwoven manufacturing industries, particularly those producing apparel, home furnishings, and industrial textiles. Exporters typically include nations with significant petrochemical industries and advanced fiber production facilities. The global trade in nylon staple fibers is influenced by demand for durable and performance-oriented textiles, as well as by competition from other synthetic and natural fibers. Key factors include fiber denier, length, and specific polyamide type (e.g., Nylon 6, Nylon 6,6), which impact their suitability for different end-uses.

Codes often confused with 5503.19
Common mistake. This code is distinct from aramid staple fibers (550311) due to the specific polyamide type, and from nylon filament tow (550110) or nylon yarns (5402xx) which are different forms of the material.

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).
