Chapter 55: Man-made staple fibres

Plain-language overview

Use HS-6 550330 when importing or exporting synthetic staple fibres made from acrylic or modacrylic that have not been carded, combed, or otherwise processed for spinning. For instance, if you're shipping a batch of acrylic staple fibres in bales for textile manufacturing, this is the correct code.

This code specifically covers synthetic fibres that are in a raw state, unlike HS-6 550320, which pertains to polyester staple fibres. If your product is a synthetic staple fibre but has been processed for spinning, you would need to look at different classifications.

When dealing with HS-6 550330, you’ll find that these fibres are commonly used in applications such as clothing, upholstery, and insulation. They are often sold in bulk packaging, typically in bales or rolls, ready for further processing.

It’s important to distinguish between synthetic fibres like those under this code and natural fibres, which fall under different classifications. If you are unsure whether your product meets the criteria for this code, consider consulting with a customs broker.
