HS-6 · Subheading
540331
Yarn, artificial; filament, monofilament (less than 67 decitex), of viscose rayon (not high tenacity), single, untwisted or twisted 120 turns per metre or less, not for retail sale, not sewing thread
Heading 5403 — Artificial filament yarn (other than sewing thread), not put up for retail sale, including artificial monofilament of less than 67 decitex
Chapter 54: Man-made filaments
Plain-language overview
Use HS-6 540331 when importing or exporting single, untwisted or twisted filament yarn made of viscose rayon, specifically those with less than 67 decitex. For instance, if you're shipping rolls of untwisted viscose rayon yarn for textile manufacturing, this is the correct code.
This code is distinct from HS-6 540332, which covers high tenacity filament yarns. If your product has a higher strength or is classified differently, you’ll need to use that code instead. Understanding the difference is crucial for proper customs clearance.
The 540331 classification includes yarns that are not intended for retail sale and are not sewing threads. This means they are typically sold in bulk to manufacturers rather than directly to consumers, which is a key factor in determining the correct HS code.
When classifying your product, consider whether the yarn is twisted beyond 120 turns per meter. If it exceeds this limit, it may fall under a different subheading, impacting your import/export documentation.
