Three salt lines from DBP
Industrial salt
Natural refined sea salt, NaCl ≥ 95% — full specification on this page.
Food-grade salt
For food processing. Specifications to your factory’s requirements.
Request specificationsApplications of industrial salt

Water treatment & softening
Regenerating the resin in water-softening systems.
Industrial processing
Tanning, dyeing, mineral supplement for animal feed, chemicals.
Seasonal stockpiling
24-month shelf life in dry storage, so you can build stock before the peak season.
De-icing salt is a winter product — but it is best bought in summer
A 24-month shelf life in dry storage lets you build up enough stock before the season, instead of buying just when the whole market needs it and freight rates rise.

Questions about refined sea salt
Can I choose a different moisture level or particle size?
Yes. Two moisture levels (≤ 3% and ≤ 6%) and two particle sizes (≤ 1.0 mm and ≤ 0.5 mm) are the most common; other specifications are discussed for each order.
What is this salt used for?
Road de-icing, water treatment and softening, industrial processing (tanning, dyeing, mineral supplement for animal feed, chemicals) and seasonal stockpiling. The specific intended use is agreed before quotation.
Can I get a sample first?
Yes. DBP sends free samples with a certificate of analysis so that your laboratory can test them before you place an order.
What is the minimum order?
There is no fixed minimum — quantity depends on the order. DBP advises you on whether a full container load or a less-than-container load suits you best.
