3916.90.10.00 - Of acrylic polymers

This HTS category, 3916.90.10.00, specifically covers rods, sticks, and profile shapes made from plastics other than those derived from acrylic polymers. These items are characterized by having at least one cross-sectional dimension exceeding 1 millimeter. The "surface-worked but not otherwise worked" clause indicates that while the surface may have undergone basic finishing like polishing or coloring, the fundamental shape and form of the plastic rod, stick, or profile remains unchanged by further manufacturing processes. Examples include extruded plastic rods for construction or manufacturing, or shaped plastic profiles used as trim or decorative elements.

The distinction of this category lies in its exclusion of acrylic polymers. Sibling categories within this level would differentiate based on the specific plastic polymer used. Therefore, if a rod, stick, or profile shape is made from materials like polyethylene, polypropylene, PVC, or polystyrene, it would fall under this heading, provided it is not an acrylic-based plastic. The "Of other plastics" designation is critical for accurate classification, requiring identification of the base polymer.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification concludes at this level. Therefore, the primary focus for importers and exporters is to correctly identify the plastic polymer composition and ensure the physical dimensions meet the criteria of exceeding 1 millimeter in any cross-sectional dimension. The absence of further working beyond surface treatment is also a key factor.
