HS-4 · Heading
5501 — Synthetic filament tow
Chapter 55: Man-made staple fibres
Plain-language overview
Use HS-4 5501 when importing synthetic filament tow, such as nylon tow used in the production of textiles or industrial applications. For example, if you're bringing in a shipment of nylon filament tow for carpet manufacturing, this code is applicable.
When determining the correct HS-6 code, consider the specific material of the filament tow. HS-6 550111 covers nylon or polyamide tow made from aramids, while HS-6 550119 is for nylon or polyamide tow that does not include aramids. This distinction is crucial for compliance and tariff purposes.
If your shipment consists of polyester filament tow, you'll need to use HS-6 550120. On the other hand, for acrylic or modacrylic filament tow, HS-6 550130 is the appropriate choice. Understanding these nuances helps ensure accurate classification and avoids potential delays or fines.
For polypropylene filament tow, refer to HS-6 550140. Lastly, if your product doesn't fit neatly into the previous categories, HS-6 550190 covers synthetic filament tow made from other materials not specified in the heading.
