9902.12.20 - Replacement doors of plastics, designed for use on waterproof camera housings (provided for in subheading 3926.90.99)

This HTS category, 9902.12.20, specifically covers replacement doors made from plastics that are intended for use with waterproof camera housings. These are specialized components designed to maintain the integrity of waterproof camera enclosures. The classification notes that these goods are provided for in subheading 3926.90.99, indicating they are a specific application of general plastic articles.

Distinguishing this category from its siblings requires an understanding of the broader HTS structure. While other sibling categories in Chapter 99 might deal with temporary legislation or specific trade agreement modifications, 9902.12.20 focuses on a particular class of goods. It is distinct from broader plastic product categories due to its highly specialized function and intended end-use in waterproof camera equipment. Classification here is driven by the dual criteria of material (plastics) and specific application (replacement doors for waterproof camera housings).

As this is a leaf node, there are no further subcategories. Classification under 9902.12.20 is definitive for the described goods. Importers should ensure that the plastic doors are indeed designed and manufactured for the purpose of replacing parts in waterproof camera housings. Any deviation in material composition or intended function would necessitate re-evaluation for classification under a different HTS heading.
