IPT issues technical opinions for customs or tax classification of products imported by areas of the pharmaceutical, veterinary and biotechnology industries for different purposes. The Institute has a multidisciplinary team of professionals (chemical engineers, pharmacists and biochemists, biologists and chemists) with recognized competence in these areas.

Depending on the type of product and, in case of questions referring to the texts of Explanatory Notes of the Harmonized System (NESH), IPT performs inspections, visits to collect data, trials on site or in the laboratory, and physicochemical analyses relating to customs or tax classification. Evaluations can be made of chemical compositions, impurities, functional groups and other parameters that may be decisive for an opinion concerning tax classification, in support of the Federal Revenue Service, the Judiciary or other interested parties.
