How to read a fluorspar COA

Why this matters

A fluorspar certificate of analysis should be easy to read and should tell a buyer whether the material fits the plant. CaF2 matters, but so do the impurity fields and moisture line.

A COA is useful only when it matches the buyer's process language. The report should tell the buyer what matters, not hide it in chemistry jargon.

Buyer checklist

If you are using this article for RFQ prep, these are the details that should be explicit before a supplier quote is meaningful.

• Check CaF2, SiO2, CaCO3, sulphur, phosphorus, and moisture.
• Confirm the unit system and whether the report is per batch, lot, or shipment.
• Ask for the inspection method if the numbers drive a contract decision.

Common mistakes

These mistakes slow down procurement or create quality surprises after the cargo lands.

• Looking only at the top-line CaF2 figure.
• Ignoring moisture because it is not the headline number.
• Failing to tie the COA to the actual shipment identification.

Practical takeaway

The best COA is the one the buyer can read, compare, and use in procurement without guesswork.
