QUALITY CONTROL
A COA is only useful if you know what was tested and on which lot. Here is the sequence.
Phosphate, ammonia, potash checked against the supplier certificate.
Slurry density and granulation parameters logged per batch.
Nutrients, moisture, hardness, chloride, heavy metals.
Against the lot number, before the goods leave.
Bag weight check and loading photos. Third-party inspection on request.

DOCUMENTS
Ask and it comes the same working day. No form gate, no sales call first.
If you would rather not rely on the producer's lab, arrange an independent inspection before loading. We cooperate with the inspector and hold the container until the report is out.
REGISTRATION SUPPORT
Some destinations require the product to be registered before it can be sold. We support the paperwork side.
Registration is granted by the authority in your country, not by us. We provide the file; the timeline is theirs.
Tell us the grade and we send the test report we have on file.
