HS-6 · Subheading
Yarn, synthetic; filament, monofilament (less than 67 decitex), of polyesters (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 540252 when importing or exporting synthetic filament yarn made from polyesters, specifically monofilament yarn that is not intended for retail sale. For example, if you're shipping a bulk roll of twisted polyester monofilament yarn used in industrial applications, this is the correct code.
This code applies to single twisted yarns with a twist of more than 50 turns per meter and a thickness of less than 67 decitex. It's important to distinguish it from HS-6 540231, which covers high tenacity yarns, as those are designed for different applications and have different properties.
When classifying your product, ensure it meets the criteria of being non-retail and not used for sewing. If your yarn is intended for use in manufacturing or as a component in other products, 540252 is likely the right choice.
Keep in mind that products under this HS-6 are typically used in various industrial applications, such as reinforcement in composites or as components in textiles, rather than for direct consumer use.
