Located in Dodoma, the capital of Tanzania, Mainland Group's sunflower seed oil base was officially commissioned in July 2025. The base is equipped with fully automated pressing, refining, filling and storage facilities, with an annual output of 35,000 tonnes of sunflower seed oil and 70,000 tonnes of sunflower meal for animal feed. It produces two local grain and oil brands, Merrin Farm and Sunland, meeting domestic demand in Tanzania while supporting exports: sunflower seed oil is sold to Europe, and sunflower meal feed is popular in Kenya.

On 31 August 2026, Hon. Dennis Lazaro Londo, Deputy Minister of Industry and Trade of Tanzania, and his delegation visited the base for an on-site inspection.

The delegation toured the automated production workshop, raw material silos and product display area to learn about actual production capacity, local employment, domestic supply and export progress. The Mainland team introduced the overall operation of the base and the market promotion of the two local brands, and reported the latest business developments: crude sunflower seed oil had been tested by SGS’s laboratory in Germany, met EU quality standards, and had completed bulk delivery to a Swiss customer.

During discussions, Deputy Minister Londo affirmed the project's local achievements, stating that Mainland's grain and oil deep-processing project effectively extended Tanzania's agricultural value chain and created many local jobs. He expressed hope that the company would continue to expand production scale, further tap export trade potential, and contribute to Tanzania’s industrialisation.

Mainland Group stated that the company will continue to put down roots in Tanzania, steadily increase production capacity and export scale, and make concrete contributions to local economic development.
