Import duty cap on vegetable saps for homeopathic medicines limits basic customs duty and waives additional duty. The Government exempts vegetable saps and extracts used in homeopathic medicines under sub heading 1302.19 from customs duty in excess of a basic duty of 35% ad valorem and from the whole of the additional duty under the Customs Tariff Act, thereby capping the basic charge and waiving additional duty on importation.
