2915.90.50.50 - Other

This HTS category, 2915.90.50.50, encompasses a residual group of saturated acyclic monocarboxylic acids and their derivatives that are not specifically listed in other subheadings within 2915.90. This includes compounds not falling under acid chlorides, which are classified elsewhere. Essentially, this subheading serves as a catch-all for saturated acyclic monocarboxylic acid derivatives that do not fit more specific classifications.

To distinguish this category, consider that while it broadly covers "Other" derivatives, the sibling category 2915.90.50.10 is specifically designated for acid chlorides of saturated acyclic monocarboxylic acids. Therefore, any compounds that are structurally acid chlorides, regardless of their other characteristics, would be classified under 2915.90.50.10 and not here. This subheading would capture other reactive derivatives like peroxides, peroxyacids, and halogenated, sulfonated, nitrated, or nitrosated derivatives of saturated acyclic monocarboxylic acids that are not otherwise specified.

As this is a leaf node, there are no further subcategories. Classification within 2915.90.50.50 relies on a thorough examination of the chemical structure and functional groups present in the compound, ensuring it meets the general scope of saturated acyclic monocarboxylic acid derivatives while specifically excluding those assigned to more precise classifications, such as acid chlorides.
