5506 — Synthetic staple fibres, carded, combed or otherwise processed for spinning
Chapter 55: Man-made staple fibres
Plain-language overview
Use HS-4 5506 when importing or exporting synthetic staple fibres that are carded, combed, or otherwise processed for spinning. For example, if you're shipping nylon fibres processed for textile manufacturing, this heading is applicable.
When deciding between subheadings, consider the specific type of synthetic fibre. For instance, HS-6 550610 covers nylon or polyamide fibres, while HS-6 550620 is for polyester fibres. It's essential to identify the fibre type to ensure accurate classification.
If your product consists of acrylic or modacrylic fibres, you would use HS-6 550630. Conversely, if your synthetic staple fibres are made from polypropylene, then HS-6 550640 is the correct choice. Each subheading has distinct material requirements.
For fibres that do not fit neatly into any of the specified categories, use HS-6 550690, which covers synthetic staple fibres not elsewhere classified. This ensures that any unique or less common synthetic fibres are still accurately reported.
