HTS Code 9902.16.89 specifically covers lamp-holder housings constructed from porcelain. These housings are designed to contain electrical sockets that are themselves classifiable under subheading 8536.61.00, which pertains to electrical lighting, signalling, or similar apparatus. The key defining characteristic of this classification is the material of the housing (porcelain) and its intended function of holding lamp sockets, thereby differentiating it from general electrical fittings or other porcelain articles.

As a leaf node within Chapter 99, this category does not have further subdivisions. Its placement within Chapter 99 signifies that it falls under temporary legislation or specific trade agreement provisions, rather than the standard categorization found in Chapters 1-97. Therefore, understanding the specific trade agreements or legislative actions that created or maintain this particular temporary code is crucial for accurate classification and compliance when importing or exporting these porcelain lamp-holder housings.
