HS Code for Aramid staple fiber

Aramid staple fiber is classified under HS code 550311, which specifically denotes "Synthetic staple fibres, of aramids, not carded, combed or otherwise processed for spinning." This classification falls within Chapter 55 of the Harmonized System, dedicated to "Man-made staple fibres." The initial digits "55" identify the material as man-made staple fibers. The "03" heading further specifies "Synthetic staple fibres, not carded, combed or otherwise processed for spinning," indicating that these are synthetic fibers in their raw, short-length form, not yet prepared for textile manufacturing processes like spinning. The final "11" precisely identifies the chemical composition as "of aramids," a class of strong, heat-resistant synthetic fibers. This detailed classification is essential for distinguishing raw aramid staple fibers from continuous aramid filaments (tow), processed aramid fibers, or finished aramid yarns, ensuring accurate customs duties, trade statistics, and regulatory compliance.

Products Included

• Raw aramid staple fibers, unprocessed
• Unprocessed meta-aramid staple fibers
• Unprocessed para-aramid staple fibers
• Short-cut aramid fibers, not carded or combed
• Aramid staple fibers in bales, not processed for spinning

Common Misclassification

Several other HS codes are frequently confused with 550311 due to similar material composition or processing stages:

• 550111 (Synthetic filament tow, of aramids): This is a common point of confusion. HS 550111 covers "Synthetic filament tow, of nylon or other polyamides, of aramids." The critical difference lies in the physical form: "tow" refers to continuous bundles of filaments, whereas "staple fibres" are short, cut lengths. While both are aramid, their distinct physical structures lead to different classifications.
• 550610 (Synthetic staple fibres, of aramids, carded, combed or otherwise processed for spinning): This code covers aramid staple fibers that *have* been carded, combed, or otherwise processed for spinning. The distinction from 550311 is the level of processing. 550311 is for unprocessed staple fibers, while 550610 is for those that have undergone initial textile preparation, such as carding or combing, making them ready for spinning.
• 540211 (High tenacity filament yarn of aramids): This code is for *yarn* made from aramid filaments, which represents a much more advanced stage of processing than raw staple fibers. The form (finished yarn versus raw fiber) is the critical differentiator, as yarn is a product ready for weaving or knitting, unlike raw staple fibers.

FAQ

What is the HS code for Aramid staple fiber?

The HS code for aramid staple fiber, specifically when it is not carded, combed, or otherwise processed for spinning, is 550311. This code identifies the raw, short-length aramid fibers.

What is the difference between aramid staple fiber and aramid filament tow for HS classification?

Aramid staple fiber (HS 550311) refers to short, cut lengths of aramid fibers. Aramid filament tow (HS 550111) refers to continuous bundles of aramid filaments. The physical form – short, discontinuous fibers versus long, continuous bundles – is the primary distinction for classification, reflecting different stages in the textile manufacturing process.
