HS-4 · 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-4 5403 when importing artificial filament yarns that are not sold in retail packaging, such as high tenacity viscose rayon monofilaments. For example, if you’re importing a bulk shipment of monofilament yarn for industrial use, this heading is applicable.
When deciding among the HS-6 subheadings, consider the material and twist of the yarn. For instance, 540310 is specifically for high tenacity viscose rayon, while 540331 and 540332 cover untwisted and twisted viscose rayon yarns, respectively. The twist level is crucial for classification.
If your product is made from cellulose acetate, you will look at 540333 for single yarns or 540342 for multiple (folded) yarns. The distinction between single and multiple yarns is important for proper classification under this heading.

- What types of yarn are included in HS-4 5403?
- HS-4 5403 includes artificial filament yarns, specifically monofilaments of less than 67 decitex, made from materials like viscose rayon and cellulose acetate.
- How do I choose between HS-6 subheadings under 5403?
- Choose based on the material and twist of the yarn. For example, select HS-6 540310 for high tenacity viscose rayon and HS-6 540331 for untwisted viscose rayon.
- What does 'not for retail sale' mean in this context?
- 'Not for retail sale' indicates that the yarn is sold in bulk for industrial use rather than in consumer packaging.
- Can I import twisted and untwisted yarns under the same code?
- No, twisted and untwisted yarns fall under different HS-6 codes. Be sure to classify them correctly based on their twist.
- What is the significance of decitex in yarn classification?
- Decitex measures the linear density of the yarn. In this heading, only yarns with less than 67 decitex are included.
