5309.21.40.90 - Other (810)

This HTS classification, 5309.21.40.90, covers woven fabrics of flax that are *not* unbleached or bleached, but rather dyed or patterned. These fabrics are characterized by containing less than 85 percent by weight of flax and are also not categorized under the narrower sibling classification for fabrics exceeding 127 cm in width.

The key distinction for this category lies in the finishing treatment of the woven flax fabric. While other subcategories might focus on the flax content percentage or the fabric's width, this specific code applies to those fabrics that have undergone dyeing or have been printed with patterns, differentiating them from their plain, uncolored counterparts.

As this is a leaf node in the HTS classification structure, there are no further subcategories. Therefore, the classification hinges entirely on the fabric being woven from flax, containing less than 85% flax by weight, and being either dyed or patterned. Examples would include brightly colored linen upholstery fabric or intricately printed linen dress material, provided they meet the aforementioned flax content and width criteria.
