In 1894 a company known as the Nyassa Company, having on its Board of Directors few former Portuguese ministers, was authorized by the Portuguese Government under Royal Decrees to administer and develop the territory of Nyassa. The company had extensive rights, including that of receiving all taxes and customs dues and of maintaining, working, and making all the means of communication in the country under its control, until 1929, when the company's rights reverted to Portugal.

Naturally the company also considered it had the privilege of issuing its own postage stamps and accordingly a set was prepared almost as soon as the company had its offices in working order, apparently with the main idea of allowing stamp collectors to do their share in providing working capital. In 1900 the company again made representations to the Portuguese Government for permission to issue stamps of distinctive design. This permission was granted and the third issue of Nyassa stamps was placed on sale on August 1st, 1901. In the period 1898-1901 Mozambique stamps with overprint NYASSA were used.

The 1901 set was comprised of 13 stamps of two different designs. First one had as its centrepiece, a giraffe and two palm trees with a range of hills as a background. In the upper corners are shields, that at the left bearing a portrait of King Carlos and that at the right the Portuguese Royal Arms. In small circles below the side inscriptions the value is shown in numerals. These stamps are upright rectangular in shape. Higher values stamps were oblong stamps with two camels forming the centrepiece. The inscriptions correspond with those on the lower values. The stamps were bi-coloured and engraved in taille-douce. They were engraved and printed by Messrs. Waterlow & Sons, Ltd., on white-wove unwatermarked paper, and were perforated 14 to 16. For some time a London dealer had an arrangement with this company under the terms of which he was permitted to purchase large quantities of these stamps cancelled to order in entire sheets at a good deal less than face value:
