### A family name. Distinct requirements.

The supplier catalog lists HEDP acid, a separately named low-chloride HEDP entry, HEDP Na2 and HEDP Na4. These names create distinct enquiry paths; they do not provide a complete specification.

If chloride is important to your purchasing specification, give the numeric maximum and test basis you require. Ask for the current grade document to confirm what the supplier’s “low chloride” label means for the proposed supply.

### Catalog variants.

Choose the name that matches your requirement. Current grade specifications and availability are confirmed through the enquiry.
