2918.21.50.00 - Other

This HTS category, 2918.21.50.00, encompasses "Other" salicylic acid and its salts, which do not meet the specific criteria for classification under sibling categories. Specifically, it includes salicylic acid and its salts that are not designated or prepared for medicinal use. This designation implies that the chemical is intended for industrial, laboratory, or other non-pharmaceutical applications.

The key distinction from the sibling category, 2918.21.10.00, lies in the intended use. While 2918.21.10.00 is reserved for salicylic acid and its salts explicitly "suitable for medicinal use," this category covers all other forms. Therefore, classification hinges on whether the product has been processed, packaged, or presented in a manner that clearly indicates its suitability for pharmaceutical applications.

As this is a leaf node, there are no further subcategories. Classification within 2918.21.50.00 is determined by the exclusion of the medicinal use criterion. Importers and exporters must ensure that the documentation and product characteristics accurately reflect the intended non-medicinal purpose of the salicylic acid or its salts to ensure correct classification.
