About HS Code 293959
This "other" category within the theophylline and aminophylline group covers all derivatives and salts of these alkaloids, excluding fenetylline, which has its own specific classification (293951). This code encompasses a range of related compounds that might be used as pharmaceutical intermediates, research chemicals, or less common therapeutic agents. Theophylline and aminophylline themselves are well-established bronchodilators, and their "other" derivatives might offer different pharmacokinetic profiles or be used in specific formulations. Trade is primarily conducted by pharmaceutical chemical manufacturers, distributors, and research institutions. Key considerations for trade include the purity standards required for pharmaceutical applications, the specific chemical form (e.g., different salts or esters), and compliance with any relevant national drug regulations, although these "other" derivatives are generally less stringently controlled than fenetylline.
Products Under This Code

Real World Examples
Diprofylline (used in some cough syrups), Proxyphylline (bronchodilator), various research-grade theophylline analogues
Common Misclassification
This code is for derivatives *other than* fenetylline; confusion might arise if fenetylline or its salts are incorrectly classified here instead of 293951.
