HS code for Acrylic staple fibers: 5506.30
Fibres, synthetic staple fibres, acrylic or modacrylic, carded, combed or otherwise processed for spinning.
Classification of acrylic staple fibers under HS 5506.30
HS code 550630 is designated for synthetic staple fibres of acrylic or modacrylic that have been carded, combed, or otherwise processed for spinning. This classification is crucial for distinguishing these prepared fibres from their raw, unprocessed counterparts. The term "staple fibres" indicates that these are discontinuous fibres, cut to a specific length, which have undergone initial mechanical processing steps such as carding or combing. These processes align the fibres, remove impurities, and prepare them into a coherent strand, making them suitable for subsequent spinning into yarn. This subheading specifically covers acrylic and modacrylic fibres that are ready for the next stage of textile manufacturing, highlighting their semi-finished state.

Codes often confused with 5506.30
Common mistake. A common misclassification point is with HS code 550330, which covers synthetic staple fibres of acrylic or modacrylic that are not carded, combed, or otherwise processed for spinning. The key distinction between 550630 and 550330 is the processing stage; 550630 is for fibres that have undergone initial preparation for spinning, while 550330 is for unprocessed fibres. Another potential area of confusion is with HS code 550961, which classifies yarn of acrylic or modacrylic staple fibres mixed with wool. While both involve acrylic staple fibres, 550630 is for the prepared fibres themselves, whereas 550961 is for the spun yarn, representing a further stage of manufacturing. Accurate classification depends on the specific processing state of the fibres.
Top exporters and importers of HS 550630 (the code used for acrylic staple fibers), 2025
In 2025, the largest exporter of HS 550630 (the code used for acrylic staple fibers) in UN Comtrade data was Peru, with about 40% of world exports; the largest importer in UN Comtrade data was Bolivia, with 19% of world imports.

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).
