3916.90.30.00 - Monofilament

This HTS classification covers monofilament made from plastics, specifically where any cross-sectional dimension exceeds 1 millimeter. It also includes rods, sticks, and profile shapes manufactured from plastics. These items, even if they have undergone surface working such as polishing or sanding, are not considered "otherwise worked" for classification purposes under this specific heading. The material composition is limited to "other plastics" not specifically enumerated in preceding subheadings.

Distinction from its sibling, 3916.90.50.00, lies in the specific nature of the monofilament. While both fall under "Of other plastics" and "Other," this category, 3916.90.30.00, is for "Other" monofilament and related shapes that do not meet the criteria for other specific subcategories (which are not detailed at this level but would typically involve more defined characteristics or material types). The key differentiator is the precise definition of "monofilament" with cross-sectional dimensions exceeding 1 mm, distinguishing it from potentially finer filaments or more complex extruded shapes.

As this node is a leaf node in the HTS structure, there are no further subcategories. Classification under 3916.90.30.00 is therefore final, provided the goods meet all preceding criteria for Section VII, Chapter 39, Heading 3916, and the "Of other plastics" and "Other" qualifiers. Examples of goods classified here might include thicker plastic fishing lines, solid plastic rods used in manufacturing, or extruded plastic strips with a single dimension exceeding 1 mm, all composed of plastics not specifically identified elsewhere in the tariff.
