HS Code 54.05 – Artificial monofilament of 67 decitex or more, no cross-sectional dimension exceeds 1mm; strip and the like (e.g. artificial straw), of artificial textile materials of a width not exceeding 5mm

HS code 5405 is a 4-digit heading in the Harmonized System that covers: Artificial monofilament of 67 decitex or more, no cross-sectional dimension exceeds 1mm; strip and the like (e.g. artificial straw), of artificial textile materials of a width not exceeding 5mm. Heading 5405 of the Harmonized System encompasses specific forms of artificial textile materials: artificial monofilament of 67 decitex or more, where no cross-sectional dimension exceeds 1mm, and strips and the like (e.g., artificial straw) of artificial textile materials with a width not exceeding 5mm. This classification is critical for distinguishing these semi-processed materials from their natural counterparts, other man-made fibers, or wider/thicker plastic products. The scope is defined by strict dimensional and material criteria; 'artificial' refers to regenerated cellulose fibers (like viscose rayon, acetate, cuprammonium) or synthetic fibers (like nylon, polyester, acrylic). Key sub-categories are primarily based on the specific type of artificial polymer used. For trade compliance, accurate classification under 5405 is vital as it directly impacts applicable duties, quotas, and trade statistics, differentiating it from raw polymers, finished yarns, or broader plastic sheets. Historically, these materials have been foundational in creating substitutes for natural fibers in various applications, from textiles to industrial uses. This heading sits within Chapter 54, which focuses on man-made filaments, acting as a gateway for continuous filament forms that are not yet spun into yarn or woven into fabric, serving as intermediate goods for further manufacturing processes.

Artificial monofilament for brush bristles, regenerated cellulose monofilament for sieves, synthetic polymer monofilament for industrial filters, acetate monofilament for specialized textiles, viscose monofilament for decorative elements, artificial raffia strips for hat weaving, artificial rattan strips for furniture repair, artificial straw for craft projects, artificial textile strips for agricultural netting, artificial monofilament for non-textile braiding, nylon monofilament for fishing lure components (bulk), polyester monofilament for medical sutures (bulk), acrylic monofilament for technical fabrics, artificial textile strips for geotextile reinforcement, cupro monofilament for specific linings, modacrylic monofilament for flame-retardant applications, polypropylene monofilament for outdoor gear components, artificial textile strips for packaging, synthetic monofilament for tennis racket strings (unstrung), cellulose acetate strips for millinery, artificial textile strips for basket weaving.

Traders often misclassify products under 5405. A common mistake is confusing it with heading 3920 or 3921, which cover other plastic sheets, film, foil, or strip. The key differentiator is that 5405 specifies 'artificial textile materials' with specific dimensional limits, whereas 3920/3921 relate to broader plastic articles not necessarily considered 'textile.' Another error is confusing it with 5404, which specifically covers *synthetic* monofilament or strip, while 5405 encompasses *artificial* (regenerated or synthetic) and includes 'strips and the like' of artificial textile materials, with similar dimensional constraints. Finally, items might be mistakenly placed in 5604 (rubber thread and cord covered with textile material) if they contain rubber, or 5808 (braids in the piece) if they are already woven or braided, rather than simple monofilaments or strips.

In 2025, the top exporters of HS code 5405 in UN Comtrade data were Japan ($4.1M, 39% of world exports), China ($2.5M) and Italy ($1.3M). World exports came to about $10M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 5405 in UN Comtrade data were China ($13M, 48% of world imports), Saudi Arabia ($3.0M) and the United States ($2.5M). World imports came to about $27M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 5405 is a 4-digit heading under Chapter 54 of the Harmonized System. The first 2 digits (54) identify the chapter, and digits 3-4 (05) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
