5211.51.00.90 - Plain weave duck (219)

This HTS classification, 5211.51.00.90, specifically covers plain weave duck fabrics of cotton that contain less than 85% cotton by weight, are mixed mainly or solely with man-made fibers, and weigh more than 200 g/m². The "duck" designation in this context refers to a sturdy, closely woven fabric, typically made with a warp of two or more threads twisted together. This particular subheading captures the broad category of plain weave duck, excluding specific constructions like poplin or broadcloth, and broader sheeting categories.

The distinction between this subheading and its siblings lies in the weave structure and the specific type of fabric designated. While 5211.51.00.20 covers poplin or broadcloth (which have a finer, often higher thread count weave), and other sibling categories address sheeting, 5211.51.00.90 encompasses other plain weave constructions that meet the weight and fiber composition criteria but do not fit the more narrowly defined sibling categories. The term "other" in the description signifies that it acts as a residual category for plain weave duck that doesn't fall into the specifically enumerated types within the same level.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, the focus for classification purposes under this heading is on accurately verifying that the imported fabric meets all the stipulated criteria: being a plain weave duck fabric, containing less than 85% cotton by weight with predominant man-made fiber blends, exceeding the 200 g/m² weight threshold, and not being classifiable under more specific woven fabric constructions at this level.
