HS Code for Synthetic filament yarn (textured)

Textured synthetic filament yarn is classified under HS code 5402.39. This is a residual category for 'other' textured yarns that do not consist of nylon (polyamides), polyesters, or polypropylene. Texturing is a mechanical or chemical process—such as twisting, crimping, or air-jetting—that transforms flat filaments into yarns with greater volume, elasticity, and a softer hand-feel. Under Chapter 54, the yarn must be a synthetic filament (not staple fiber) and must not be put up for retail sale. The classification 5402.39 is used for specialized polymers like acrylic or modacrylic filaments that have been textured. The technical distinction between textured and non-textured yarn is vital; textured yarns have physical distortions in the filaments that do not disappear under low tension, providing the bulk necessary for specific knitting and weaving applications in the garment industry.

Products Included

• Textured acrylic filament yarn
• Textured modacrylic filament yarn
• Bulked synthetic filaments (non-polyester/nylon)
• Crimped synthetic yarns for industrial knitting
• Air-jet textured specialized synthetic filaments

Common Misclassification

The most common error is classifying these yarns under 5402.31 (nylon) or 5402.33 (polyester). Because polyester and nylon dominate the market, 5402.39 is often overlooked. Another misclassification is 5402.44, which is for elastomeric yarns; while both have stretch, textured yarns achieve elasticity through physical shape rather than the chemical nature of the polymer. If the yarn is made of staple fibers, it must be moved to Chapter 55.

FAQ

What is the HS code for textured synthetic yarn?

For textured synthetic filament yarns other than nylon, polyester, or polypropylene, the HS code is 5402.39.

What does 'textured' mean in HS classification?

It refers to yarn that has been processed to have curls, crimps, or loops, increasing its volume and giving it a 'spun' appearance despite being a continuous filament.
