Moluccan products were shipped to trading emporiums in India, passing through ports like Kozhikode in Kerala and through Sri Lanka. From there they were shipped westward across the ports of Arabia to the Near East, to Ormus in the Persian Gulf and Jeddah in the Red Sea and sometimes to East Africa, where they were used for many purposes, including burial rites. The Abbasids used Alexandria, Damietta, Aden and Siraf as entry ports to trade with India and China. Merchants arriving from India in the port city of Aden paid tribute in form of musk, camphor, ambergris and sandalwood to Ibn Ziyad, the sultan of Yemen.
