Indian salt vs Australian salt is mostly a question of where you are, what purity you need and how much you buy. Both countries make solar salt by evaporating seawater or brine, and both export in bulk, so the comparison turns on freight, specification and shipping scale.
Australia is a long-established bulk exporter to Asia. India, led by Gujarat and Kutch, supplies industrial, chlor-alkali, de-icing and some edible grades.
How is the salt made?
Both origins rely on solar evaporation in large pans, followed by harvesting, washing and screening. The differences come from the brine, the climate, the pan management and the processing after harvest.
That is why you should buy on tested properties, not origin. See why Kutch produces salt for how the Indian side works.
Be careful with comparisons on a delivered basis. A quote from one origin may be FOB the loading port while another is CIF your discharge port, and the difference can hide a large part of the cost. Ask each supplier to quote the same basis, the same quantity and the same tolerance. Also check whether the weight is determined at loading, by draft survey or weighbridge, and who pays for that. Our guide to comparing chemical quotes applies equally to bulk minerals.
What specification matters for industrial use?
The key properties are sodium chloride content, moisture, insolubles, calcium, magnesium and sulphate, and particle size. Chlor-alkali plants are particularly sensitive to calcium, magnesium and sulphate, because they affect brine purification.
Grades differ by use, as shown in salt grades: industrial, edible and de-icing, and purity targets are discussed in industrial salt purity. Write your limits into the contract and ask for a certificate on each shipment.
Finally, think about reliability, not only the quote. Ask how many vessels the supplier has loaded in the last year, to which ports, and whether any were delayed by weather or port congestion. Salt is a continuous-use input for plants, and a missed vessel can cost more than any saving on the unit rate.
How do freight and shipping compare?
Salt is low in value per tonne, so freight is a large part of landed cost. Distance to your port, vessel size and port draft usually decide which origin is competitive, and these can change from one year to the next.
India is closer to the Gulf, East Africa, South Asia and parts of South-East Asia. Australia is closer to North-East Asia and Oceania. Bulk vessel, bags and jumbo bags each have trade-offs, set out in how salt is shipped.
What should you check before choosing India?
If India is on your shortlist, test these points:
- Whether the supplier works the pans or buys from others, and how lots are blended.
- Moisture control during stockpiling, especially in the monsoon months.
- Loading arrangements at the port, including draft and loading rate.
- An independent check of weight and quality at loading, as covered in checking moisture and purity at loading.
- Experience with your end market, such as chlor-alkali or road de-icing.
