5513.12.00.00 - 3-thread or 4-thread twill, including cross twill, of polyester staple fibers (617) 🖩

This HTS classification, 5513.12.00.00, specifically covers woven fabrics manufactured from polyester staple fibers. The defining characteristic of these fabrics is their weave structure: a 3-thread or 4-thread twill, which includes cross twill patterns. These textiles are further qualified by their composition, containing less than 85 percent polyester staple fibers by weight, with the remainder primarily cotton, and a maximum weight not exceeding 170 grams per square meter.

To differentiate this category from its siblings, it is crucial to focus on the weave. Unlike 5513.11.00, which pertains to plain weave fabrics, this category exclusively addresses twill weaves. Category 5513.13.00 encompasses other woven fabrics of polyester staple fibers that do not fit the specific twill structure or the plain weave defined elsewhere. Category 5513.19.00 covers broader "other woven fabrics" categories within the synthetic staple fiber chapter.

As this HTS code represents a leaf node, there are no further subcategories. Therefore, the practical application of this classification hinges on the accurate identification of the twill weave structure (3-thread or 4-thread, including cross twill) and confirmation of the material composition and weight specifications. Examples of products falling under this code might include certain types of workwear fabrics, durable upholstery materials, or specialized linings where a twill weave in a polyester/cotton blend is a key design element.
