Purchasing guide / Version 1.0
Plan the purchase through receiving and replenishment
Carry the approved material identity, documentation, and packaging requirements into the order.
Make the quote request usable
Record the approved product or specification, supplied concentration, required quantity, preferred packaging, delivery timing, and receiving constraints. Distinguish the estimated system fill from the quantity procurement has authorized. Ask the supplier to confirm the available configuration rather than assuming every container size is stocked.
Keep the evidence with the shipment
Our suggested receiving record includes the ordered product identity, delivered label, lot identifier, available lot documentation, container condition, and the person responsible for resolving discrepancies. Preserve the purchasing requirement alongside the received documents so later reviews have context.
- Which documents must be available before receipt?
- What storage conditions are specified by the supplier?
- Can the receiving location handle the proposed containers?
- Who records the lot and disposition of the material?
Document what is already in the system
For replenishment or a proposed change, identify the existing fluid and the governing equipment instructions before requesting a replacement. Dow recommends assessing compatibility against specific system conditions and equipment requirements; matching a chemical name alone is not sufficient justification for a substitution.
Put the questions into a purchasing brief
Record your equipment requirements and unresolved questions. Export the brief for your engineering team or supplier.
