More information from the manufacturer:

Copper Sulphate Pentahydrate:

In designing and presenting this quality product, emphasis was given to:

Product Uses:   

Melpat Copper Sulphate has a number of applications:

• Registration in Rice to control snail populations,
• Fertiliser,
• EU-Approval as animal feed grade

Product Quality:

The quality of this product is of such a high standard that it meets animal-feed grade standards set by the EU (for further details refer to the Technical Note: Dioxins in Copper Products).

Product Consistency:

Melpat Copper Sulphate is consistent in quality from batch to batch. It is not a traded product where product is purchased from whoever is cheapest on the day.

Product Purity and Cleanliness:

Heavy metals are a natural phenomenon in copper in the raw state, and so - prior to production of any Melpat copper products - the raw material is ‘cleaned’. As a consequence of this, the levels of the undesirable heavy are extremely low, e.g. Lead levels are around mid-20ppm, which is less than 10% of the maximum permissible level.                       

Solubility:           

Rapid solubility is desirable and emphasis was given to maximise surface area in order to achieve this. The crystal particle size range is 0.1mm – 0.6mm. THAT IS SMALL.
