01Our story Our story

From a small line to a regional supplier

Our growth comes from steady investment in technology, the laboratory and people — not from sudden leaps. Every stage of development began with one question: how can the quality of our consignments be made more provable?

2011Founded

Mahan Chemical Company, Bandar Imam — a producer of caustic soda — started its activity in 1390 (2011) with the production of caustic soda flakes. Through the hard work of its employees, alongside the development goals of the management, the company was able to reach 45 tonnes of solid caustic soda flakes per day in 1394 (2015) by expanding its production line and increasing capacity.

Mahan Chemical Company of Bandar Imam holds a special position in Iran’s industry today. The company’s caustic soda flakes are a strategic, high-quality product that has earned the company this position, to the point where its considerable production tonnage can play a critical role in the growth of domestic industry.

By drawing on an elite chemical engineering team in its research and operations, the company has achieved a favourable quality level in its products. Its round-the-clock production process, running across three working shifts while keeping product quality consistently high, reflects the company’s commitment to production.

In marketing and trade, Mahan Chemical Company employs expert and committed staff at all hours of the day and night, and is able to meet every requirement and handle all matters relating to contracts, as well as shipping to all parts of the country and abroad.

03Our values Our values

Four principles behind every decision

These principles are not wall decoration; they are written into our production procedures, our raw-material purchasing criteria and our contracts.

Measurable quality

Every claim must carry a number: analysis of each batch, batch-number traceability, and retention of a reference sample.

Safety, no exceptions

Working with a corrosive substance demands discipline — from personal protective equipment to work permits and emergency drills.

Sustainable production

Optimising energy use in the evaporators and the flaking unit, effluent management, and compliance with environmental requirements across the site.

Customers as partners

A dedicated technical specialist, samples before purchase, and long-term supply contracts with a defined delivery schedule.

04Production site Production facility

One continuous chain, under one roof

From liquid caustic intake and control through concentration, flaking, packing and loading, every stage takes place on one site so that quality control is never interrupted.

05Quality & HSE Quality · Health · Safety

A lab that signs off, a team that works safely

Quality and safety are two sides of one coin: both require documented methods, continuous training and precise data recording.
