Inventory & materials planning · Chemicals & coatings
No stockout, no expired drum.
An MRP signal fires but the planner confirms lead times and watches shelf life so reactive resins don't expire. Miss it and a batch stops.
The reality
Raw materials expire.
Chemical inventory isn't just quantity — it's shelf life and FIFO. Resins, hardeners, and catalysts have expiry dates, and a drum consumed out of order or held past its date is scrap. The planner is balancing reorder points, supplier lead times, and use-by windows on every material.
The operator owns the plan. It reads the MRP signal, raises the purchase requisition, confirms the supplier's lead time, enforces FIFO consumption, and watches expiry dates — so the line never stops for a missing material and nothing ages out on the shelf.
How the operator runs inventory & materials planning
Material RM-2208 · MRP
reviewing- Reorder point breached — epoxy resin
- On-hand 1.2t · open PO none
- Net requirement vs plan — confirming
01Review the MRP signal
Reads the reorder signal, checks on-hand and open POs, and confirms what's truly short against the production plan.
Req PR-5510 · Supplier
requesting- Requisition raised — 3t
- Lead time confirmed — 10 days
- Delivery date — aligning to run
02Raise the requisition
Raises the purchase requisition, confirms the supplier's lead time, and times delivery to the production window.
Stock RM-2208 · FIFO
tracking- Oldest lot sequenced first
- Stock plan updated
- Lot L-441 expiry in 21d — flagged
03Enforce FIFO and expiry
Updates the stock plan, sequences FIFO consumption, and flags any lot approaching its shelf-life date.
The outcome
−60% of materials-planning work off the team
No stockout, no expired inventory.
- Reorder signals acted on before the line runs short
- FIFO enforced so reactive materials are used in date order
- Shelf-life expiries flagged before a drum becomes scrap
