Why Peak Season Stress-Tests Labeling Systems

The challenge with peak season isn't that failure rates increase because shipping volume increases. The problem is scale.

Peak Volume Magnifies Small Labeling Problems

Labeling issues that exist during normal operations amplify when shipping volumes surge.

Even facilities running high levels of automation with exceptional barcode scan performance feel this impact. Take a distribution facility maintaining a 99.9% first-pass scan rate. When processing 10,000 daily shipments, a 0.1% exception rate yields a manageable 10 packages requiring manual intervention. But when peak demand pushes throughput to 50,000 packages daily, that identical error rate results in 50 exceptions. Facilities operating with lower efficiency experience even harsher disruptions.

The core reliability of the labeling technology remains unchanged, but the volume of processing exceptions the facility must manage expands significantly.

This scaling effect similarly impacts other intermittent labeling failures. Occasional printer jams, a peeling label, or a degraded barcode all become major operational hurdles during volume spikes.

That's why peak-season preparation should focus on how consistently your labeling system performs. A problem you overlook during normal volumes may deserve another look before Q4 shipment counts increase.

Barcode Scan Accuracy

Accurate barcode read rates are essential for automated fulfillment. This is another area where failures can significantly impact performance during high-volume periods.

Operations typically monitor barcode quality to ensure accurate read rates, but barcode placement is another critical factor. Automated scanning requires positioning the symbol where it will pass through the fixed scanner's field of vision as the package moves past it.

Contrast is another important consideration. A barcode must provide sufficient contrast between the bars and background for a scanner to distinguish the encoded information. Insufficient contrast increases the risk of a read error.

These aren't isolated concerns. Research from GS1 US found that 70% of logistics operations experience barcode readability issues at least weekly. Poor label quality, inconsistent labeling, and outdated scanning systems are among the causes.

3PL and Retailer Requirements Can Create Relabeling Risk

Products can encounter several different labeling requirements as they travel through the supply chain. For example:

• A manufacturer labels the product and carton before shipping it to a 3PL.
• The 3PL receives and stores the inventory, then picks and packs products to fulfill orders.
• Shipments then move to a retailer distribution center, marketplace fulfillment network, parcel carrier, store, or directly to the customer.

Not every step requires relabeling. In fact, different labels often serve different purposes throughout the process.

Properly formatted labels organize information into separate supplier, customer, and carrier segments. This allows a single logistics label to contain the information needed at different points in the supply chain.

Problems arise when an inbound shipment doesn't satisfy the requirements of the next organization handling it.

A retailer, marketplace, 3PL, or carrier may have requirements governing barcode symbology, encoded information, label dimensions, placement, carton identification, routing information, or shipping labels. A missing or unreadable barcode, incorrect label placement, or incompatible identification scheme can require intervention before it continues.

In addition, labeling requirements can change. If those requirements aren't aligned, incompatible barcodes, incorrect placement, or missing destination-specific information can trigger relabeling and rework at downstream facilities.

During peak season, that rework is particularly costly because it introduces another manual process when fulfillment operations are trying to maximize throughput.

Before volume increases, review labeling requirements with the organizations that will actually receive, handle, and ship your products. Standardize requirements where possible. Identifying differences where standardization isn't possible can reduce surprises later.

Audit Your Labeling Processes Before Q4

Assess your operation before the increased demands of Q4. The goal isn't simply to determine whether your labels "work." It's to identify the exceptions your operation routinely absorbs and ask what happens when shipment volume increases substantially.

What to Audit Before Q4 Hits

Take these steps to make sure you're prepared before package volume increases.

Test Label Adhesion in Cold and Damp Conditions

A shipping label that performs perfectly in a climate-controlled packing area may operate differently once it leaves the building.

During fall and winter, packages can move between heated facilities, cold trailers, exposed loading docks, and outdoor environments. Rain, snow, and the moisture caused by condensation from temperature changes, combined with normal package handling, can expose labels to moisture and abrasion, which contribute to label failure.

In addition, cold temperatures can directly affect pressure-sensitive adhesives. Applying labels at room temperature and then distributing packages in cold weather, or applying labels at cold temperature and moving them to a climate-controlled warehouse, can cause general-purpose adhesives to fail.

To ensure your operations maintain their productivity, ask these questions before peak season:

• Do your labels work effectively on the actual corrugated cartons, shrink wrap, plastic totes, or other surfaces used in your operation? If not, which surfaces cause problems?
• Is the label adhesive designed to go from a normal fulfillment center temperature to the cold conditions of an outside dock or truck trailer?
• Similarly, if you apply labels in cold temperatures, is the adhesive designed to perform when it's delivered to a temperature-controlled warehouse?
• Does information printed on the label remain legible after typical weather conditions and routine handling?

Verify Barcode Scan Rates

Evaluate barcode readability in your actual production environment using your operational printers, scanners, label materials, packaging surfaces, and placement standards.

• Placement and packaging surface checks — Ensure barcodes are placed on smooth surfaces with adequate clear space around the symbol. Avoid placing labels near carton edges or seams, on uneven surfaces, wrapping them around packaging, or covering them with other materials.
• Print and label quality checks — Inspect for damaged or wrinkled labels, as well as barcodes showing marginal print contrast or resolution.
• Scanning performance metrics — Gauge first-pass scan rates across your operations. Determine how many packages scan successfully on the first attempt, identify which package types or production areas generate the most exceptions, and pinpoint whether failures track back to specific printers, locations, or label materials.

Measure these results and identify problematic areas now so your operation has time to correct them before peak season.

Reduce Relabeling Risk Across Logistics Touchpoints

If your internal labeling process is ready for peak season, that doesn't necessarily mean the entire fulfillment chain is.

Review the labeling requirements of your 3PLs, major retailers, marketplaces, and other fulfillment partners. Confirm barcoding and data requirements and label placement. Non-compliant processes can result in financial penalties.

Just as importantly, talk with logistics partners about upcoming changes. New customers, fulfillment locations, carriers, packaging configurations, warehouse systems, or marketplace requirements can all change what needs to appear on a package.

Peak season is not the ideal time to discover those differences.

Don't Treat Peak-Season Labeling as a One-Time Exercise

The same issues that surface during holiday fulfillment can affect operations throughout the year.

• Retail and e-commerce fulfillment — Promotions, product launches, flash sales, and other predictable spikes can create many of the same pressures as holiday shipping. Maintaining adequate label inventory and reliable printing and scanning processes helps operations respond without introducing unnecessary bottlenecks.
• 3PL and warehouse operations — Third-party logistics providers continuously manage products from multiple customers. Standardized processes and reliable label performance can help reduce exceptions as volume and customer complexity increase.
• Cold chain and weather-exposed shipping — Cold temperatures, moisture, and temperature transitions aren't limited to the holidays. Organizations shipping refrigerated products or operating in cold environments need label materials and adhesives selected for those conditions year-round.

Peak-season preparation not only ensures your operation can meet the typical fourth quarter demand spikes, it identifies areas that may be creating unnecessary costs during normal operations.
