5512.21.00.50 - Duck (219) 🖩

This HTS classification covers woven fabrics made predominantly from synthetic staple fibers, specifically those containing 85% or more by weight of acrylic or modacrylic staple fibers. These fabrics are further characterized as being either unbleached or bleached. The "Duck" designation (219) signifies a specific type of weave or construction commonly associated with this category, often characterized by a plain weave with a high thread count, resulting in a durable and tightly woven fabric.

This category is distinguished from its siblings by the specific weave or fabric construction identified by the term "Duck." For instance, siblings include fabrics classified as poplin or broadcloth, sheeting, printcloth, cheesecloth, lawns, voiles, batistes, and satin or twill weaves. While all these fabrics fall under the broader umbrella of woven acrylic or modacrylic staple fiber fabrics, the "Duck" classification points to a particular structural characteristic that differentiates it for customs purposes.

As a leaf node in the HTS system, there are no further subcategories beneath 5512.21.00.50. Therefore, classification within this code relies on a precise identification of the fabric's composition (at least 85% acrylic/modacrylic staple fiber), its state (unbleached or bleached), and its weave or construction being consistent with what is commonly understood and documented as "Duck" fabric within the textile trade.
