HS Code 5509.11 – Yarn; (not sewing thread), single, of synthetic staple fibres, containing 85% or more by weight of nylon or other polyamides, not put up for retail sale
HS code 5509.11 is the 6-digit subheading for yarn, (not sewing thread), single, of synthetic staple fibres, containing 85% or more by weight of nylon or other polyamides, not put up for retail sale. It is used for single nylon 6 yarn, single nylon 6,6 yarn, single polyamide staple fiber yarn, high-tenacity nylon single yarn and abrasion-resistant polyamide yarn.
What HS 5509.11 covers
This HS code encompasses single yarns made from synthetic staple fibers, specifically those with a high concentration (85% or more by weight) of nylon or other polyamides, and not prepared for retail sale. These industrial-grade yarns are fundamental inputs for textile manufacturers producing durable fabrics, carpets, and technical textiles. Their strength, abrasion resistance, and elasticity make them highly sought after in various applications. Major importers are often countries with robust textile manufacturing sectors, such as China, India, Turkey, and the USA, which process these yarns into finished goods. Exporters typically include nations with strong petrochemical and fiber production capabilities like China, Taiwan, South Korea, and European countries. Understanding the denier, filament count, and specific polyamide type (e.g., Nylon 6, Nylon 6,6) is crucial for traders, as these characteristics dictate the yarn's performance and suitability for different end-uses.

Codes often confused with 5509.11
Common mistake. This code is distinct from 550912 (multiple/cabled nylon yarn) due to its single strand nature. It could also be confused with other synthetic staple fiber yarns (e.g., polyester in 550921) if the polyamide content is not accurately declared.

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).
