5309.29.30.90 - Other (810)

This HTS classification, 5309.29.30.90, specifically designates woven fabrics of flax that contain less than 85% flax by weight. The "Other (810)" description indicates that this is a residual category for such fabrics not falling into more specific classifications within this sub-chapter. The key determinant for inclusion here is the material composition, where flax is present but does not constitute the predominant fiber by weight.

This category is distinguished from its sibling categories, "Subject to cotton restraints" and "Subject to man-made fiber restraints," by its focus on the absence of specific restraint agreements applicable to cotton or man-made fibers within these flax-containing fabrics. While the underlying fabric is woven flax and contains less than 85% flax, the absence of any mention of cotton or man-made fiber restraints in this specific sub-heading means it covers fabrics where these restraints, if applicable, do not dictate its placement at this level of detail.

As this is a leaf node, there are no further subcategories. Therefore, classification within 5309.29.30.90 relies solely on the preceding criteria: woven fabric of flax, containing less than 85% flax by weight, and not fitting into more narrowly defined classifications at higher levels. Examples might include intricate weaves or specialized finishes of flax-based fabrics where cotton or man-made fibers are present as minor components, but the primary characteristic remains flax, without triggering specific trade restrictions on the other fibers.
