Caustic Soda for Alumina and Metallurgy
In the smelting industry caustic soda is used to manufacture aluminium hydroxide alumina and metal surface treatment agents. In hardware electroplating it serves as an electroplating solution and as a conductor, and it is also used in tungsten smelting.
Industry Pain Points
What Goes Wrong With The Wrong Supplier
- Large continuous consumers cannot tolerate an interrupted supply
- Impurities carried in with the alkali accumulate in a recirculating liquor
- Bagged product at high tonnage creates a lot of manual handling
- Long ocean legs mean packaging has to survive months in transit
Customer Requirements
What This Industry Actually Needs
- Container volumes on a repeating schedule
- Declared carbonate chloride and iron limits
- Jumbo bags where the site can handle them
- Robust dry sealed packaging for long voyages

Alumina and Metallurgy Questions
Answers to the questions buyers ask us most often before placing a first order
Yes. We load around 80 containers a month and build rolling schedules for repeat buyers. See our bulk supply programme.
Flakes in jumbo bags usually give the lowest handling cost per tonne. Solid is chosen where the site prefers a compact form with less exposed surface.
Export products are checked by quality inspection agencies such as SGS CIQ and INTERTEK. You choose the agency and the inspection point.
