2939.42.00.00 - Pseudoephedrine (INN) and its salts

This HTS classification covers pseudoephedrine, a widely recognized sympathomimetic amine and its various salt forms. Pseudoephedrine is primarily known for its medicinal use as a decongestant in over-the-counter and prescription medications for the common cold, allergies, and sinus conditions. Its classification is specific to the chemical compound and its salts, not finished pharmaceutical products which would be classified elsewhere.

Distinguishing this category from its siblings, it is crucial to note that 2939.42.00.00 exclusively pertains to pseudoephedrine and its salts. This differentiates it from ephedrine (2939.41.00.00), cathine (2939.43.00.00), norephedrine (2939.44.00.00), and metamfetamine (2939.45.00.00), all of which are distinct chemical compounds within the alkaloid family, each with their own specific chemical structures and regulatory considerations.

As a leaf node within the HTS structure, this category does not have further subdivisions. Therefore, classification under 2939.42.00.00 is determined by the presence of pseudoephedrine or its pharmaceutically acceptable salts. Importers and exporters must ensure accurate identification of the chemical substance to ensure correct tariff classification and compliance with any applicable regulations pertaining to precursor chemicals.
