Shelf-life-sensitive materials are used in semiconductor, battery, solar, and other high-tech manufacturing processes. Their suitability depends not only on the printed expiry date but also on how much usable time remains after shipment, receiving, storage, and planned consumption.
A material may therefore meet its specification at the supplier while having too little remaining life for the manufacturer’s production schedule.
This Work Smarter video shows how LineWorks SQM, a camLine Supplier Quality Management solution, automates incoming-material shelf-life checks at different supply-chain stages. It provides earlier visibility into whether the material has sufficient remaining life for the intended use.
Why the Printed Expiry Date Is Not Enough
An expiry date shows when the approved shelf-life period ends, but it does not determine whether the remaining time is sufficient for a particular delivery and production plan.
Quality and material teams may also need to consider:
- expected transport duration;
- the actual receiving date;
- planned storage time;
- the time required before consumption; and
- the minimum remaining life required at a specific decision point.
If these factors are reviewed only when material reaches production, teams may discover too late that the batch cannot be used within the accepted window.
How LineWorks SQM Evaluates Remaining Shelf Life
LineWorks SQM can evaluate remaining shelf life at several points using the relevant dates and rules defined by the manufacturer.
Four Decision Points for Incoming-Material Shelf-Life Control
| Decision point |
How the shelf-life information is used |
| Before supplier shipment |
Considers the expected logistics duration and the remaining life required when the material arrives. |
| During receiving |
Recalculates the remaining life using the actual arrival information and expected time before use. |
| During inventory planning |
Shows which available batches have less remaining life and may require earlier attention. |
| Before production allocation |
Helps teams avoid assigning a batch to a production plan that cannot consume it within the approved window. |
Reliable decisions depend on authoritative manufacturing and expiry dates, agreed calculation rules, and accurate material and batch identification.
Use Remaining Shelf Life to Support Material Planning
Current remaining-life information helps planners and warehouse teams determine which materials should be considered first for production.
It can support FIFO-based inventory decisions and make batches approaching their accepted limit visible before they become unusable. It can also prevent a material from being allocated to a plan that requires more time than the batch has remaining.
Automated checking does not remove the need for controlled exceptions. Retesting, approved extensions, transport delays, temperature excursions, or customer-specific requirements may still require quality review and documented approval.

FAQ
Q: Why should shelf life be checked before material reaches production?
A: A material can meet its specification at shipment yet have too little remaining life after transport, receiving, storage, and planned consumption. Checking only the printed expiry date at the line may lead to late rejection or waste.
Q: How can LineWorks SQM evaluate shelf life during shipment and receiving?
A: Before shipment, the workflow can consider the expected logistics duration and required remaining life. At receiving, it can recalculate using the actual arrival and the time expected before use. This gives procurement, warehouse, and quality teams an earlier basis for acceptance or exception handling. Reliable decisions require authoritative manufacture and expiry data and agreed calculation rules.
Q: How does shelf-life visibility support FIFO and waste reduction?
A: Real-time remaining-life information helps teams prioritize material that should be consumed first and avoid allocating a batch to a plan it cannot complete within the approved window.
LineWorks SQM supports that decision with traceable batch context. FIFO alone may not be sufficient when materials have different conditions, retest dates, customer restrictions, or approved extensions.
Q: What exceptions should be designed into an automated shelf-life check?
A: Plan for missing or conflicting dates, transport delays, partial deliveries, opened containers, controlled extensions, retesting, temperature excursions, changed production schedules, and customer-specific minimum life.
Define which conditions block receipt or issue, who may approve an exception, and how the rationale and affected quantity are recorded. Automated checking should make the decision rule explicit, not bypass quality authority.
