3925.30 - Shutters, blinds (including venetian blinds) and similar articles and parts thereof:

This HTS category, 3925.30, specifically covers shutters, blinds, and similar articles manufactured from plastics, along with their associated parts. These items are designed for controlling light, privacy, or weather exposure, and are typically installed on windows, doors, or other architectural openings. The classification hinges on the primary function of light or privacy control and the use of plastic as the principal material.

It is important to distinguish this category from its siblings within builders' ware of plastics. While 3925.20.00 covers doors, windows, their frames, and thresholds, this category focuses on functional coverings or closures for such openings, not the structural elements themselves. Similarly, it differs from 3925.10.00.00, which pertains to large plastic containers, and 3925.90.00.00, which is a residual category for other plastic builders' ware not elsewhere specified.

Within this category, further subdivisions exist to refine classification based on product type. Subcategory 3925.30.10.00 is dedicated to blinds, explicitly including venetian blinds, which are characterized by horizontal slats that can be adjusted. The remaining articles falling under the umbrella of shutters, blinds, and similar items, not specifically covered by the blind subcategory, are classified under 3925.30.50.00, encompassing items like roller shutters or louvred shutters.
