Mexican Bulk Solar & Rock Salt (Isla de Cedros / Baja California)
High-purity Pacific solar & rock halite — winter highway de-icing & chlor-alkali feedstock
Mexican bulk marine solar salt and mineral halite harvested from the vast hypersaline coastal lagoons of Guerrero Negro, Baja California Sur, and loaded through the deepwater marine logistics terminal at Isla de Cedros, represents the largest single-site salt manufacturing and ocean export complex in the world. With an annual production run-rate exceeding 8.0 to 9.0 million metric tonnes, the operation produces halite with exceptional chemical purity consistently ranging between 98.5% and 99.5% NaCl on a dry basis, featuring native low moisture (<1.20% post-drainage/handling) and vanishingly low insoluble matter (<0.15%). The material is crushed, screened, and calibrated to meet rigorous highway de-icing standards including ASTM D632 Type I Grade 1, Ontario OPSS.PROV 2502, and Quebec BNQ 2410-200, as well as ultra-pure uninhibited feedstocks (0 ppm YPS) for electrochemical chlor-alkali membrane electrolysis.
Under CBIL Commercial Doctrine Rule 24, prospective municipal buyers, provincial agencies, and regional salt distributors can bypass the financial commitment and demurrage liability of a 50,000 MT charterparty by initiating a verified Starter-Trial. We execute 1 to 2 container test pilots (25 to 50 MT) packed in 1,000 kg heavy-duty polypropylene FIBC bags with 100 µm polyethylene inner liners, supplied with 21 days demurrage-free detention at Canadian (Montreal, Halifax, Toronto) and US Northeast ports. This enables real-world laboratory assays, spreader auger calibrations, and storage dome pile kinetics to be tested on-site. For deepwater receiving terminals along the St. Lawrence Seaway and US Atlantic seaboard, 3,000 to 5,000 MT partial bulk test parcels are available via co-discharge stems. Every consignment is inspected and certified at the Isla de Cedros loading terminal by SGS or Intertek for ASTM chemical assay, sieve gradation, moisture limits, and calibrated 50–100 ppm Yellow Prussiate of Soda (YPS) anti-caking application.

Mexican Bulk Solar & Rock Salt (Isla de Cedros / Baja California) — buyer questions
How does Mexican salt from Guerrero Negro compare in purity and moisture to Chilean and Moroccan salt?
Guerrero Negro salt is harvested from clean, high-salinity Pacific seawater lagoons with long natural solar evaporation cycles, yielding exceptionally high purity (98.5% to 99.5% NaCl) and minimal insolubles (<0.15%). While Chilean rock salt is mined dry at <0.20% moisture, Mexican solar salt undergoes intensive washing, centrifuge mechanical dewatering, and controlled stockpile draining prior to barge haulage to Isla de Cedros. Loaded moisture is maintained at ≤1.20%, and automated dosing with 50 to 100 ppm YPS prevents cryo-caking and pile crusting during winter discharge into Eastern Canada.
What are the vessel loading economics and draft parameters at Isla de Cedros?
Isla de Cedros is an offshore deepwater terminal in Baja California sheltered from Pacific heavy swells, with berth depths of 16.5 to 19.0 meters. Unlike shallow coastal loading points, Isla de Cedros can berth vessels from Handysize up to Capesize (up to 150,000 DWT) with high-velocity conveyor loaders operating at 2,000 to 3,500 MT/hr. Vessels bound for the St. Lawrence Seaway transit the Panama Canal as Panamax or Ultramax tonnage, discharging deep at Montreal or Contrecoeur.
How is the Rule 24 Starter-Trial protocol executed for North American municipal tenders?
To satisfy strict qualification criteria under Ontario (MTO), Quebec (UMQ/Ville de Montréal), and US state DOT contracts without committing to a 45,000 MT vessel stem, buyers can order a 1 to 2 container pilot (25 to 50 MT) packed in 1,000 kg FIBC bags with 21 days container free time. This allows road authorities and maintenance contractors to run certified laboratory sieve and purity assays and test real auger discharge rates in municipal spreaders before the main summer tender fill.
How does freight routing work between Isla de Cedros, Montreal, and Hamilton?
Ocean bulk vessels (typically 50,000 to 65,000 DWT Ultramax) steam south along the Pacific coast of Mexico, transit the Panama Canal, and sail up the North American Atlantic coast into the St. Lawrence River to Montreal or Contrecoeur (~16.5 days steaming). Because the St. Lawrence Seaway locks beyond Montreal have an 8.08m (26.5 ft) draft limit, bulk salt bound for Hamilton, Toronto, or Cleveland is efficiently transshipped onto high-capacity Canadian self-unloading Lakers, delivering at total CIF costs between and /MT.
