9902.01.78 - Mixtures containing titanium dihydride pastes of a kind used for coating the interior of low-pressure mercury lamps (CAS No. 7704-98-5) (provided for in subheading 2850.00.07)

This HTS classification, 9902.01.78, specifically designates mixtures containing titanium dihydride pastes that are intended for coating the interior of low-pressure mercury lamps. The key identifier for these mixtures is their particular application in the manufacturing of specific lighting components. The inclusion of the CAS number 7704-98-5 further aids in precise identification. This provision is made under Chapter 99, which houses temporary legislation and modifications.

While the broader HTS system includes numerous categories for various substances and materials, this specific classification distinguishes itself by its highly specialized nature and intended end-use. Unlike general chemical classifications or those for bulk industrial materials, 9902.01.78 is narrowly focused on a component crucial for a particular type of lamp. Its purpose is not for general chemical use but as a specific coating agent.

As a leaf node within the HTS database, 9902.01.78 has no further subcategories. Therefore, the focus for classification under this code is on ensuring the material meets the description precisely, particularly its composition as a titanium dihydride paste and its declared use in the interior coating of low-pressure mercury lamps. This ensures that only the intended, highly specialized product is classified under this temporary provision.
