HS-6 · Subheading
540310
Yarn, artificial; filament, monofilament (less than 67 decitex), of high tenacity viscose rayon, not for retail sale, not sewing thread

Chapter 54: Man-made filaments
Plain-language overview
Use HS-6 540310 when importing or exporting high tenacity viscose rayon monofilament yarn that is not packaged for retail sale. For example, if you're shipping a bulk roll of this yarn for industrial use, this is the correct code.
This code specifically covers monofilament yarns made from viscose rayon with a thickness of less than 67 decitex. It's important to differentiate this from other filament yarns under the same heading, such as those made from synthetic fibers or those that are put up for retail sale.
When classifying yarn, consider the end-use. If the yarn is intended for applications like weaving or manufacturing technical textiles, 540310 is appropriate. In contrast, if the yarn is for sewing, you would need to look at different codes, such as those for sewing thread.
Understanding the nuances between this HS-6 and similar codes can help avoid misclassification. For instance, 540320 covers synthetic filament yarns, which would not apply to high tenacity viscose rayon.
