In the world of warehouse logistics and material handling, organization and flow are everything. One of the most fundamental inventory strategies used to ensure efficiency and product quality is FIFO, or First-In, First-Out. Understanding how FIFO works—and choosing the right pallet racking system to support it—is critical for maintaining smooth operations, reducing waste, and maximizing storage efficiency.
What is FIFO?
FIFO is an inventory management principle where the first items stored are also the first items to be picked and shipped. This method is especially important for industries dealing with expiration dates—such as food, beverage, pharmaceuticals, and consumer goods—where proper product rotation helps ensure freshness and compliance with safety regulations. By prioritizing older stock, FIFO reduces the risk of spoilage, obsolescence, or costly write-offs. But successful FIFO execution requires more than just good intentions—it demands the right pallet racking system to enable consistent and logical product flow.
Pallet Rack Systems Ideal for FIFO
To make FIFO work effectively, your warehouse needs a racking solution that supports front-to-back product flow. Here are the most effective pallet rack systems for FIFO operations:
Pallet flow racking is the gold standard for FIFO. This high-density system uses slightly inclined rollers or wheels to allow pallets to glide from the loading side (rear) to the picking side (front). As one pallet is removed, the next one automatically takes its place.
Advantages:
Perfect for high-throughput FIFO operations
Maximizes space utilization
Reduces travel time for pickers
Great for perishable or date-sensitive inventory
Unlike drive-in racking (which supports LIFO), drive-through racks are accessible from both ends. Products are loaded from one side and unloaded from the opposite side, maintaining a FIFO sequence.
Advantages:
Accommodates large volumes of similar SKUs
Suitable for fast-moving inventory
Requires fewer aisles, increasing storage density
A pallet shuttle system uses a semi-automated or fully automated shuttle to move pallets within a deep lane racking structure. Operators load pallets onto the shuttle at one end, and the shuttle transports the load to the next available position. FIFO configurations can be achieved with dual-access lanes.
Advantages:
High-density storage with reduced forklift travel
Increased throughput and labor efficiency
Suitable for cold storage and high-volume SKUs
Scalable and automation-friendly
For light-duty, hand-picked items, carton flow racks offer the same gravity-fed FIFO benefits as pallet flow racks but for cases and individual cartons.
Advantages:
Ideal for order picking environments
Supports high SKU counts with excellent visibility
Increases accuracy and ergonomics for pickers
Factors to Consider When Selecting a FIFO Rack System
When evaluating the best FIFO pallet rack system for your warehouse, consider the following:
Product type & shelf life
Load weights and pallet sizes
SKU diversity and pick frequency
Available warehouse space
Level of automation or manual picking
Implementing a FIFO strategy in your warehouse isn’t just a best practice—it’s often a necessity. Whether you're handling time-sensitive goods or simply looking to streamline your inventory rotation, choosing the right pallet rack system is a critical step.
Pallet flow racks are still one of the most efficient FIFO solutions, but drive-through racking, pallet shuttle systems, and carton flow racks offer flexible and scalable options depending on your operational needs. Additionally, integrating FIFO systems with warehouse management software (WMS) can further improve inventory control, reduce human error, and enhance traceability.
