3926.90.99.40 - Covers, rings and frames for manholes; catch basins; drainage gates and frames thereof; cleanout covers and frames thereof; valve, service and meter boxes

This HTS code, 3926.90.99.40, specifically classifies plastic articles designed for infrastructure and utility access points. It encompasses items such as covers, rings, and frames intended for manholes, catch basins, and drainage gates. Additionally, it includes frames for cleanout covers, as well as boxes designed to house valves, services, and meters. These articles are typically manufactured from various plastics and are characterized by their structural and protective functions in underground or exposed utility systems.

Distinguishing this category from its siblings involves recognizing the specific application and form factor. For instance, while other subcategories within 3926.90.99 might cover personal protective equipment like face masks (3926.90.99.50) or general industrial items, this code is narrowly focused on components that facilitate access to and protection of subterranean infrastructure. Elastic bands or laboratory ware, for example, serve entirely different purposes and possess distinct physical characteristics, thus falling under separate classifications.

As this is a leaf node, there are no further subdivisions under 3926.90.99.40. Classification into this specific code hinges on the precise identification of the article's function as a cover, ring, frame, or box for manholes, catch basins, drainage gates, cleanouts, or utility meter/service boxes, and its material composition of plastics. The emphasis is on the item's role in public works and utility management.
