Products classified under Tariff item 55.04
Antibacterial Viscose Rayon Staple Fibers 1.3 denier 37mm
Silver-ion antibacterial viscose rayon staple fibers, 1.3 denier and 37mm, in raw unprocessed form for use in medical textiles. The silver-ion treatment imparts antibacterial properties but does not constitute carding, combing, or other processing for spinning, so the fibers remain classified as artificial staple fibres of viscose rayon.
5504.10.00Bamboo Viscose Rayon Staple Fibers 1.4 denier 39mm
Bamboo-derived viscose rayon staple fibers, 1.4 denier and 39mm, in raw unprocessed form for eco-friendly yarn production. Although derived from bamboo pulp, the regenerated cellulose qualifies as viscose rayon, and the fibers are not carded or combed, so they fall under this tariff item.
5504.10.00Bright Viscose Rayon Staple Fibers 2.25 denier 44mm
Bright (non-delustered) viscose rayon staple fibers, 2.25 denier and 44mm, raw and unprocessed for spinning into lustrous yarns for fashion fabrics. The bright finish does not constitute processing for spinning, so the fibers remain classified as artificial staple fibres of viscose rayon.
5504.10.00High-Wet-Modulus Viscose Staple Fibers 1.2 denier 34mm
High-wet-modulus (HWM) viscose rayon staple fibers, 1.2 denier and 34mm, unprocessed for premium spun yarns in dress shirts and linens. HWM viscose is a specialized type of viscose rayon with improved wet strength, but it remains an artificial staple fibre not carded or combed, so it falls under this tariff item.
5504.10.00Modal Viscose Rayon Staple Fibers 1.0 denier 36mm
Modal viscose rayon staple fibers, 1.0 denier and 36mm, unprocessed for spinning into soft intimate apparel yarns. Modal is a type of viscose rayon with high wet strength, and since the fibers are not carded or combed, they fall under this tariff item as artificial staple fibres.
5504.10.00Organic Viscose Rayon Staple Fibers 1.6 denier 41mm
Certified organic viscose rayon staple fibers from sustainable pulp, 1.6 denier and 41mm, raw for spinning. Organic certification does not affect the tariff classification, and the fibers are unprocessed viscose rayon staple, so they fall under this tariff item.
5504.10.00Recycled Viscose Rayon Staple Fibers 2.0 denier 43mm
Post-consumer recycled viscose rayon staple fibers, 2.0 denier and 43mm, mechanically processed but not carded or combed for spinning. The recycling process does not constitute processing for spinning, so the fibers remain classified as artificial staple fibres of viscose rayon.
5504.10.00Viscose Rayon Conductive Staple Fibers 2.5 denier 45mm
Carbon-infused conductive viscose rayon staple fibers, 2.5 denier and 45mm, unprocessed for antistatic textiles. The carbon additive provides conductivity but does not change the fiber's essential character as viscose rayon staple, and the fibers are not carded or combed, so they remain under this tariff item.
5504.10.00Viscose Rayon Flame Retardant Staple Fibers 2.0 denier 42mm
Flame-retardant treated viscose rayon staple fibers, 2.0 denier and 42mm, in raw unprocessed form for safety textiles. The flame-retardant treatment does not constitute carding, combing, or spinning processing, so the fibers remain classified as artificial staple fibres of viscose rayon.
5504.10.00Viscose Rayon Microfiber Staple 0.8 denier 32mm
Ultra-fine microfiber viscose rayon staple fibers, 0.8 denier and 32mm, unprocessed for microfiber yarn spinning. The fineness of the fibers does not affect classification, and since they are not carded or combed, they fall under this tariff item as artificial staple fibres.
5504.10.00Viscose Rayon Staple Fibers 1.5 denier 38mm
Unprocessed viscose rayon staple fibers, 1.5 denier and 38mm, used primarily for spinning into yarns for apparel and textiles. These are standard artificial staple fibres of viscose rayon, not carded or combed, so they fall under this tariff item.
5504.10.00Viscose Rayon Staple Fibers 3 denier 51mm
Unprocessed viscose rayon staple fibers, 3 denier and 51mm, ideal for spinning into coarser yarns for upholstery and towels. The coarser denier does not affect classification, and the fibers are not carded or combed, so they fall under this tariff item.
5504.10.00Viscose Rayon Staple Fibers for Nonwovens 1.7 denier 40mm
Unprocessed viscose rayon staple fibers optimized for nonwoven production, 1.7 denier and 40mm, not carded for spinning. The intended end-use (nonwovens) does not affect classification, and since the fibers are not carded or combed, they fall under this tariff item.
5504.10.00Viscose Rayon Staple for Paper Yarn 3.5 denier 55mm
Coarse viscose rayon staple fibers, 3.5 denier and 55mm, for blending with paper in specialty yarns, unprocessed. The intended use in paper yarn does not affect classification, and the fibers are not carded or combed, so they fall under this tariff item.
5504.10.00Viscose Rayon Tow for Staple Conversion 20,000 denier
Continuous viscose rayon tow of 20,000 total denier, unprocessed except for basic drafting, intended for cutting into staple fibers. However, this tariff item applies only to staple fibres, not tow. The tow is excluded from heading 55.04 because it is not cut to staple length, so it does not fall under this item.
5504.90.00Bamboo Viscose Staple Fiber
Bamboo viscose staple fiber in its raw, unprocessed state, produced through the viscose process from bamboo pulp. These fibers are not carded, combed, or otherwise processed for spinning, making them suitable for textile yarn production. They fall under this tariff item as artificial staple fibres not further processed.
