Industrial & De-icing Rock Salt

Bulk solar and rock salt for de-icing and chlor-alkali

Industrial salt is the largest-volume commodity nobody prices carefully, because the cargo is worth less than the ship that carries it. Solar salt harvested from evaporation pans and rock salt mined from halite beds both trade on the same short sheet: sodium chloride 96–99.5% on a dry basis, moisture (2–5% for solar, under 1% for rock), insolubles, calcium and magnesium (which matter for chlor-alkali brine purity and set the membrane-cell grade apart from de-icing grade), sulphate, and a size distribution that decides whether it spreads from a gritter or dissolves in a saturator at rate. De-icing buyers, the municipalities and highway authorities of Canada, the northern United States and northern Europe, want a coarse 2–10 mm product with an anti-caking additive and accept lower purity; chlor-alkali plants want 99% plus with calcium and magnesium under a few hundred ppm, and pay for it. The 2025 declarations show the scale: India exported 19.5 million MT under HS 2501, half of it to China and a fifth to Korea, at an average USD 17–20 per MT FOB; Morocco exported 494,000 MT, 44% to the USA and 39% to Canada at USD 19–38; and Canada imported 1.31 million MT, from Mexico 470,000 MT, Brazil 310,000 MT, Chile 305,000 MT and Morocco 192,000 MT. Egypt reports its salt exports by value only, with the USA among its partners.

At USD 15–40 per MT FOB the freight is one to two times the cargo, so an industrial salt enquiry is a freight enquiry wearing a cargo's clothes, and the winner is whoever fixes the ship best: a Supramax or Panamax on a contract of affreightment for the de-icing season, loading at 8,000–15,000 MT a day from a stockpile with a conveyor or grab, discharging into a port stockpile before the first frost. CBIL is a commodity brokerage company and brokers industrial salt from Indian, Mexican, Chilean, Moroccan, Egyptian and Australian producers and trader positions against SGS or Intertek certification of NaCl, moisture, insolubles, calcium, magnesium, sulphate and sizing, on FOB, CFR and CIF terms; because CBIL also runs a chartering desk (LaycanDesk), the annual freight contract is priced with the cargo rather than left to the buyer, which for this commodity is most of the delivered price. Send the grade (de-icing or chemical), the monthly tonnage and window, the discharge port and its stockpile arrangement, and we will work the producer and the tonnage together.

Excluded origins are not offered, including product re-exported, blended or re-processed through a third country. Every lot moves with a certificate of origin naming the producing plant, mine or grower country, and nothing is quoted before the seller and loading point are known.

Industrial & De-icing Rock Salt — buyer questions

Why is the freight quote more important than the FOB price?

Because at USD 15–40 per MT FOB the cargo is worth less than the voyage. A Supramax from the Mediterranean or Mexico to the St Lawrence costs more per tonne than the salt in it, so the delivered price is decided on the chartering desk, not the salt pan. We price the contract of affreightment with the cargo so you see one delivered number.

What is the difference between de-icing and chemical grade?

De-icing salt is coarse, 2–10 mm, treated with an anti-caking agent and accepted at 96–98% NaCl; it is bought on price and spreadability. Chemical grade for chlor-alkali is 99.5% plus with calcium, magnesium and sulphate held low, because those ions foul membrane cells. Specifying chemical grade for road use pays for purity the gritter cannot use.

What loading rates and parcel sizes are normal?

25,000–35,000 MT Handysize and 50,000–60,000 MT Supramax and Panamax lots. Solar salt loads from stockpiles by conveyor at 10,000–20,000 MT a day; rock salt from mine stockpiles by grab or loader at 5,000–10,000 MT a day. A de-icing programme is usually contracted as monthly liftings for the season rather than spot voyages.

Can you supply Canada and the northern USA?

Yes, and the reference lane is Morocco and Mexico into Montreal and the US East Coast, alongside Chile and Brazil. Canada imported 1.31 million MT in 2025 by its own customs data. We work a new origin against that benchmark and against the receiver's stockpile and berth, and price the season's freight with it.
