Overview

At Shah Mercantile Co., we deliver high-purity Himalayan rock salt that meets the demanding specifications of the food, pharmaceutical, industrial, and de-icing sectors. Sourced from the ancient salt ranges of Pakistan and processed under strict quality control, our salt is trusted for its purity, performance consistency, and tailored granulation.

We understand that when you buy salt, you’re not just sourcing a commodity—you’re securing an ingredient or raw material that must meet critical regulatory, operational, and commercial standards.

Whether you need edible salt for refined food applications, de-icing rock salt for winter contracts, or industrial-grade for chemical synthesis, we ensure that every granule is up to spec, every time.

Performance Advantages

For Food & Pharma:

<0.005 ppm heavy metals
Complies with global pharmaceutical-grade salt specs.
Fortified with stable iodine
Meets WHO recommendations for universal salt iodization.

For De-Icing:

92% ice melting efficiency at -25°C (ASTM D740)
Superior coverage and fast reaction even in extreme cold.
Granule uniformity (2-5mm)
Minimizes clumping, ensures consistent spread rate.

For Industrial/Chemical:

High sodium chloride yield (99.8%)
Ideal for chlor-alkali production and reagent-grade solutions.
Low insolubles (<0.15%)
Prevents blockages and tank sedimentation in fluidized systems.

Purity & Processing Assurance

Our end-to-end quality control system is built to prevent contamination and maintain mineral integrity:

Brine-Washing
All edible and industrial salt grades are washed using filtered natural brine to maintain mineral balance without introducing chemical residues.
Metal Detection & Magnetic Separation
Embedded detection units eliminate risk of ferrous contamination in the crushing and sieving process.
Clean Packaging Environment
Halal, Kosher, and BRCGS compliant packaging facilities ensure your salt arrives free from foreign odor, residue, or microbial interference.
Moisture-Resistant Packing
Food-grade salt is packed in laminated PP woven bags with PE liner. De-icing and industrial grades are available in bulk bags or HDPE sacks.

Sizes & Applications

Size Range	Application
0.1 – 0.5mm	Table salt, food processing
2 – 5mm	De-icing, snow control
Powder (<75μm)	Industrial, chemical synthesis

Need a custom size or blend? We offer on-demand granulation within ±0.1mm tolerance for large volume buyers.

Buyer Pain Points We Solve

❱ Inconsistent Purity

We maintain strict batch-level traceability and third-party verification of purity, iodine levels, and insolubles—eliminating guesswork and ensuring compliance.

❱ Risk of Moisture Caking

With our brine-dried, low-humidity salt and lined packaging, your salt will remain free-flowing, even in humid environments or long transits.

❱ Poor De-icing Performance

Our calibrated de-icing salt melts faster and spreads more evenly, helping municipalities and contractors lower salt usage by up to 16%.

❱ Skepticism Toward Sourcing from Pakistan

We understand the market concerns and are here to change that. Shah Mercantile Co. brings radical transparency, traceable sourcing, and uncompromising documentation—allowing you to source confidently from Pakistan.
