5607.50 - Of other synthetic fibers:

HTS Code 5607.50 encompasses twine, cordage, ropes, and cables that are specifically manufactured from synthetic fibers, excluding those made from polyethylene or polypropylene. These articles may be plaited or braided, and can be further processed through impregnation, coating, covering, or sheathing with rubber or plastics for enhanced durability, water resistance, or other functional properties. The key distinguishing factor for this category is the primary synthetic fiber content, which is not derived from the specific polymers listed in sibling categories.

Within this category, classification hinges on the type of synthetic fiber used. For instance, while 5607.50 covers ropes made of nylon or polyester, a separate sibling category exists for ropes of polyethylene or polypropylene. This distinction is crucial for accurate tariff application, as different materials may carry varying duty rates.

The subcategories within 5607.50 further refine the classification based on the construction of the rope, twine, or cordage. The primary subdivision distinguishes between braided or plaited constructions and those that are not. This allows for granular differentiation based on manufacturing processes and the resulting physical characteristics and intended applications of the finished product.
