HS-6 · Subheading
Yarn, synthetic; filament, monofilament (less than 67 decitex), of nylon or other polymides (not high tenacity or textured), single, twisted more than 50 turns per metre, not for retail sale, not sewing thread
Heading 5402 — Synthetic filament yarn (other than sewing thread), not put up for retail sale, including synthetic monofilament of less than 67 decitex
Chapter 54: Man-made filaments
Use HS-6 540251 when importing or exporting synthetic monofilament yarns made from nylon or other polyamides, specifically those twisted more than 50 turns per meter. For example, if you're shipping a roll of nylon monofilament yarn used in fishing lines, this code applies.
This code is distinct from HS-6 540250, which covers synthetic monofilament yarns that are not twisted and have a different application. If your product is a single filament yarn that is not twisted, you should consider that classification instead.
The 540251 line specifically addresses yarns that are not high tenacity or textured, ensuring clarity in classification. If you have synthetic yarn that is high tenacity or textured, it would fall under a different HS code.
When dealing with synthetic filament yarns, it's crucial to note that this classification is for yarns not put up for retail sale. If your product is packaged for retail, you will need to look at other codes.
