03Buying it in bulk

Buying it in bulk

Specification first. Put the grade, assay method and the physical parameters you care about into your purchase specification, and ask that the COA reports against them. "High purity" alone leaves the interpretation to whoever is testing.

Confirm the lead-time tier. Ready stock ships immediately; sourced-to-order adds a procurement window. On a tight schedule this matters more than unit price.

Documents before price. Ask for the Specification Sheet and a recent batch COA at quotation stage so QA can review while commercial terms are still open.

Include freight. Indicative prices are on an ex-Shanghai basis; freight is separate. Consolidating several SKUs into one shipment lowers the cost per kilogram.
