About Us

frontJames Cumming & Sons Pty Ltd was established in Australia in 1909 by James Cumming and members of his family, manufacturing Ironfounders’ Blacking using technology developed from owning and operating similar manufacturing plants in Scotland.

The company is still owned and operated by members of the Cumming family, and the rock and ore milling and refining plant is still located on the block of land in Western Sydney that James Cumming originally purchased from Auburn Real Estate Agent Jack Lang, who later became famous as NSW Premier during the Great Depression.

The company is a household name throughout the Iron and Steel Industry. James Cumming & Sons was an original supplier to Australian Iron & Steel when it established a spun pipe plant at Port Kembla, on the site of the present Bluescope Steel works.

During the 1980’s, the company recognised a need to diversify the markets in which it operated, and developed new coal and carbon products to service those markets.

The water treatment industry had been importing anthracite filter media in growing quantities, and there were no Australian producers of a viable equivalent.

In 1984, the present Managing Director, John Cumming identified a High Rank Coal in NSW which possessed all the properties necessary to produce a high performance anthracite coal-type filter media, and meeting the requirements of the AWWA/ANSI B100 Standard for Filtering Materials. At the same time, the Rock and Ore Milling Plant in Sydney was extended and modified to produce C&S Brand Australian Filter Coal to meet the growing market demand for this media.

While James Cumming & Sons sees the water treatment industry as its main area of operation, it continues to serve other industries with a range of coal and carbon products. These industries include:

  •  Iron & Steel Manufacture
  •  Glass Manufacture
  •  Oil Refining and Lubricants
  •  Pyrotechnics Manufacture
  •  Friction Products Manufacture

James Cumming & Sons Pty Ltd is a Quality Endorsed Company, certified to the International Quality Standard AS/NZS ISO 9001
