Customs exemption for FSMPs used in rare disease treatment permitted on import subject to certified medical authorization. A new tariff entry S. No. 607B exempts from basic customs duty Drugs, Medicines or Food for Special Medical Purposes (FSMP) used for treatment of rare diseases specified in List 38, provided imported for personal use and accompanied by a certificate from specified health authorities as prescribed in newly inserted Condition 115; failure to produce the certificate or acceptable undertaking will render the importer liable to pay duty. The amendment also inserts List 38 enumerating specified rare diseases and makes related updates to medical and textile machinery concession entries.
