HS Code for Polyamide tow

Polyamide tow is classified under HS code 5501.19 because it consists of synthetic filament tow of nylon or other polyamides, excluding aramids. According to the Explanatory Notes to Chapter 55, filament tow must meet specific criteria: it must exceed 2 meters in length, have a twist of less than 5 turns per meter, and the filaments must be of a decitex of less than 67. This specific subheading is reserved for polyamides that do not fall under the aramid category, which is 5501.11. The classification is determined by the material composition and the physical state of the fibers, which are intended to be cut into staple fibers for further processing in the textile industry. The General Rules of Interpretation (GRI) 1 and 6 are applied here, as the product is specifically named in the nomenclature. The tow is a collection of parallel filaments of a uniform length, which distinguishes it from bundles of waste or staple fibers that have already been cut. Polyamide, commonly known as nylon, provides high strength and elasticity, making this tow a vital raw material for producing spun yarns used in carpets, apparel, and industrial textiles. Furthermore, the tow must be capable of being drawn to at least three times its original length to be considered synthetic filament tow under this chapter. If the tow is made of artificial fibers like rayon, it would be classified under 5502. The distinction between 5501.11 and 5501.19 is purely based on the chemical structure of the polyamide, where aramids are separated due to their high heat resistance.

Products Included

Common Misclassification

Polyamide tow is frequently confused with HS code 5501.11, which is specifically for aramids (aromatic polyamides). While both are polyamides, aramids have distinct chemical properties and are classified separately. It is also often misclassified under 5402, which covers synthetic filament yarn. The distinction lies in the length and the lack of twist; tow is a bundle of filaments intended to be cut, whereas yarn is intended for weaving or knitting directly.

FAQ

What is the HS code for Polyamide tow?

The HS code for polyamide tow (other than aramids) is 5501.19.

How does tow differ from staple fiber?

Tow consists of continuous, parallel filaments that have not yet been cut, while staple fibers (classified in 5503) are fibers of a specific, finite length produced by cutting the tow.
