Common questions

How do I choose a grade?

Start from your process. Our fertilizer solutions page lists the grades to evaluate for granulation, organic-mineral, water-soluble, micronutrient, SC and WP, and soil conditioner products.

What documents do you send?

The TDS and SDS for the grade, a representative COA before you order, and a COA with every lot.

How are products packed?

Powders ship in 20–25 kg bags or 500–600 kg jumbo bags; humates also in 25 kg paper bags; liquids in IBCs. Container loading is agreed per destination.
