Heading 5509Yarn (other than sewing thread) of synthetic staple fibres, not put up for retail sale

Chapter 55: Man-made staple fibres

Plain-language overview

Use HS-6 550931 when importing or exporting yarn made from synthetic staple fibers, particularly those containing 85% or more acrylic or modacrylic. For instance, if you’re shipping a bulk order of single yarn for textile manufacturing, this code applies.

This code specifically covers yarn that is not intended for retail sale. If you are dealing with packaged yarn for consumers, you would need a different classification. Compare this with HS-6 550932, which includes similar yarn types but is specifically packaged for retail.

The 5509 heading narrows down the focus to yarns made from synthetic fibers, excluding sewing threads. This is important to note as sewing threads are classified separately, and using the wrong code could lead to customs delays.

When classifying your products, remember that this HS-6 line is for single yarns only. If your product is a multi-ply yarn or a different fiber composition, you would need to look at other subheadings under 5509.
