HS code for Acrylic staple fiber: 5503.30
Fibres, synthetic staple fibres, acrylic or modacrylic, not carded, combed or otherwise processed for spinning.
Classification of acrylic staple fiber under HS 5503.30
HS code 550330 specifically classifies synthetic staple fibres composed of acrylic or modacrylic polymers. The defining characteristic for inclusion under this subheading is that these fibres have not undergone any further processing such as carding, combing, or other preparations typically performed before spinning. This classification is critical for accurately identifying raw, unprocessed acrylic staple fibres, distinguishing them from those that have already entered the initial stages of textile manufacturing. The term "staple fibre" denotes that these are discontinuous fibres, cut to a specific, manageable length, contrasting with continuous filaments. The explicit exclusion of processed fibres ensures that 550330 is reserved for the most basic form of these synthetic fibres, serving as a fundamental raw material for a wide array of textile applications where subsequent processing will be carried out.

Codes often confused with 5503.30
Common mistake. A frequent point of misclassification involves HS code 550630, which is designated for synthetic staple fibres of acrylic or modacrylic that have been carded, combed, or otherwise processed for spinning. The fundamental distinction between 550330 and 550630 rests entirely on the processing stage; 550330 is strictly for unprocessed fibres, while 550630 applies to fibres that have undergone initial preparation, making them ready for the spinning process. Another potential area of confusion is with HS code 550130, which classifies synthetic filament tow of acrylic or modacrylic. The key difference here is that 550130 refers to continuous bundles of filaments (tow), whereas 550330 specifically covers discontinuous, cut staple fibres. Understanding these distinctions is vital for correct customs declaration and trade compliance.
Top exporters and importers of HS 550330 (the code used for acrylic staple fiber), 2025
In 2025, the largest exporter of HS 550330 (the code used for acrylic staple fiber) in UN Comtrade data was Japan, with 47% of world exports; the largest importer in UN Comtrade data was China, with 27% 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 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).
