3821.00.00.10 - Viral transport media

This HTS category specifically classifies prepared culture media designed for the development or maintenance of micro-organisms, including viruses, as well as plant, human, or animal cells. These media are formulated with essential nutrients and growth factors to support the life processes of specific biological entities in laboratory settings. They are typically supplied in a ready-to-use form, either dehydrated or liquid, and are distinguished by their intended biological application.

As this is a standalone category at its level, there are no direct siblings to differentiate it from. However, it is important to note that general chemical compounds or non-prepared biological materials would not fall under this classification. The defining characteristic is the preparation of the medium with the specific intent of supporting cellular or microbial growth.

The sole subcategory, 3821.00.00.90, covers all other prepared culture media not specifically categorized as viral transport media. This allows for the classification of a broader range of culture media used for various microbiological, plant cell, or animal cell culture applications, ensuring that all such specialized biological growth media are appropriately accounted for within the tariff schedule.
