HS Code 5505.10 – Fibres; waste (including noils, yarn waste and garnetted stock), of synthetic fibres
HS code 5505.10 is the 6-digit subheading for fibres, waste (including noils, yarn waste and garnetted stock), of synthetic fibres. It is used for polyester yarn waste, nylon fibre noils, acrylic garnetted stock, polypropylene spinning waste and synthetic fabric offcuts.
What HS 5505.10 covers
This category covers various forms of waste generated from synthetic fibre production and processing, including noils (short fibres removed during combing), yarn waste (leftovers from spinning or weaving), and garnetted stock (fibres reclaimed from fabric or yarn waste). This trade is crucial for the circular economy within the textile industry, as it provides raw material for recycling and reuse. Importers are typically recycling plants, non-woven fabric manufacturers, and producers of low-cost yarns or filling materials. Exporters are textile mills, garment factories, and fibre producers looking to manage their industrial waste efficiently. Key considerations include the purity of the waste, its composition (e.g., polyester, nylon), and the form it takes, as these factors determine its suitability for various recycling processes and end products like insulation, geotextiles, or regenerated fibres. The global push for sustainability has significantly increased the demand and value of these waste materials.

Codes often confused with 5505.10
Common mistake. This code can be confused with 550520 (waste of artificial fibres) due to both being fibre waste, but the distinction is critical: 550510 is specifically for synthetic fibres (e.g., polyester, nylon), whereas 550520 is for artificial fibres (e.g., rayon, acetate).
Top exporters and importers of HS code 550510, 2025
In 2025, the largest exporter of HS code 550510 in UN Comtrade data was Belgium, with 16% of world exports; the largest importer in UN Comtrade data was Italy, with 17% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
