First Expired, First Out
FEFOFirst Expired, First Out is an inventory management method that prioritizes using materials with the earliest expiration date first.
First Expired, First Out (FEFO) is a system for organizing and retrieving inventory. It ensures that items with the soonest expiration dates are selected before items with later dates. This method is critical for managing perishable goods or materials with a limited shelf life.
On the shop floor, FEFO requires accurate tracking of expiration dates for each batch or lot of material. When a component is received, its expiration date is recorded in an inventory management system. Storage locations are organized to allow access to specific lots. When a work order requires a material, the system directs personnel to pick the lot that will expire first, regardless of when it arrived.
FEFO is important for reducing waste and costs associated with expired inventory. It helps manufacturers avoid scrap and maintain product quality and safety. For industries like food, pharmaceuticals, and chemicals, FEFO is essential for regulatory compliance. It ensures that finished goods are made from valid components and meet safety standards.
Manufacturers implement FEFO using a Warehouse Management System (WMS) or an MES with an inventory module. These systems track lot numbers and expiration dates from receiving to production. Barcode or RFID scanners are commonly used to automate data capture and enforce picking rules. This reduces human error and provides a reliable audit trail.
A pharmaceutical plant receives two lots of an active ingredient. Lot A expires on June 1st and Lot B expires on July 15th. Even if Lot B arrived first, the inventory system directs the operator to use Lot A for the next production batch to prevent it from expiring.
What is the difference between FEFO and FIFO?
FEFO prioritizes the earliest expiration date, while First-In, First-Out (FIFO) prioritizes the oldest stock by arrival date. They often produce the same result, but FEFO is more precise for perishable goods.
Which industries use the FEFO method?
FEFO is used in industries with perishable goods or materials with a shelf life. This includes food and beverage, pharmaceuticals, chemicals, and cosmetics manufacturing.
How do you handle two batches with the same expiration date?
If two lots have the identical expiration date, the system typically defaults to the FIFO method. The lot that was received first is used first.
Can I implement FEFO without an inventory management system?
A manual FEFO system can use physical tags and dedicated storage areas. However, it is more labor-intensive and susceptible to errors than a system using barcode scanning and a WMS.
Does FEFO increase warehouse handling costs?
It can if older stock is not easily accessible. Proper warehouse layout, slotting strategies, and specialized racking can minimize any increase in handling time.
First-In, First-Out
FIFOFirst-In, First-Out (FIFO) is an inventory management method where the first materials received are the first ones used in production or shipped.
Last-In, First-Out
LIFOLast-In, First-Out (LIFO) is an inventory management method that assumes the last items added to stock are the first ones to be sold or used.
Warehouse Management System
WMSA Warehouse Management System (WMS) is software that directs and optimizes warehouse operations from receiving to shipping.
Traceability
Traceability is the ability to track a product's history, location, and components from raw materials to the final customer.
Scrap Rate
Scrap rate is the percentage of material that is wasted during a manufacturing process and cannot be used in a finished product.
