How Diesel Prices and Freight Capacity Affect Manufacturing

With current diesel prices, it's important to dive in to understand how this volatility and other factors affect your supply chain and manufacturing. In this article we will discuss:

• Current issues with capacity
• Fuel prices
• Qualified capacity
• Building resilience, and
• Reducing risk

Current Capacity Issues

For manufacturers that depend on precise, compliant, and time-sensitive deliveries, available transportation capacity is not always usable capacity. While freight conditions have stabilized in recent months, underlying pressure continues to build.

• Diesel prices remain volatile, operating costs are high, and difficult market conditions have led some carriers to reduce their fleets or leave the industry altogether.
• Transportation networks are also more sensitive to seasonal demand, weather, policy changes, and other disruptions.

Truck availability is only part of the equation. High-stakes manufacturing operations often require qualified drivers, proper equipment, and specialized handling.

A Market with Less Room for Error

Recent stability does not mean shippers have the same flexibility they once did. Several factors are narrowing their options:

• Carrier exits: Fewer providers can reduce available freight capacity.
• Higher operating costs: Insurance, equipment, labor, and fuel costs continue to pressure carriers.
• Stricter requirements: Driver and equipment standards can further limit qualified options.

With fewer trucks in the market, capacity may tighten even without a major surge in freight demand. The impact will not be felt equally across every lane. Availability varies by region, transportation mode, equipment type, and timing. For example, a weather event, policy change, or local increase in demand can quickly narrow a shipper's options.

Plan Ahead

Review critical lanes, special requirements, and delivery windows before capacity becomes urgent.

Diesel Price Volatility Reaches Beyond the Fuel Surcharge

Diesel is one of the largest operating costs in trucking, but its impact extends beyond the fuel surcharge. Price volatility can influence:

1. The cost of empty miles and equipment repositioning
2. The loads and lanes carriers are willing to accept
3. Where carriers position trucks and equipment
4. Whether financially vulnerable carriers can remain in business

Diesel-market conditions are shaped by more than crude oil prices alone. Distillate inventory levels, refinery production, exports, and seasonal demand can all affect domestic supply and pricing.

Lower inventories do not automatically mean freight capacity will become unavailable. However, sustained diesel-market pressure can affect operating costs, lane decisions, equipment positioning, and transportation planning.

These effects may also extend across borders. For example, proposals to restrict U.S. diesel exports could affect markets such as Mexico and other parts of Latin America that rely on U.S. diesel for trucking, agriculture, and manufacturing. Changes in regional fuel availability could then influence cross-border transportation and the movement of goods and manufacturing inputs into the United States.

For critical materials, the greater concern is whether changing market conditions will limit access to qualified transportation capacity.

Why Qualified Capacity Matters

In regulated and high-stakes supply chains, capacity only matters when it fits the shipment. Depending on the material and lane, qualified freight capacity may require:

• Specialized equipment
• Trained drivers
• Documented operating procedures
• Temperature controls
• Security measures and permits
• Emergency response capabilities

A truck that is available but does not meet these requirements may not be a viable option.

Service Matters

A missed pickup or late delivery can disrupt production, inventory, site operations, and customer commitments. Carrier selection should consider safety, visibility, communication, and response plans rather than price alone.

Protecting Access to Qualified Capacity

During a disruption, manufacturers with complex needs compete for a smaller group of qualified providers. Strong carrier relationships, clear forecasts, and agreed-upon expectations can help protect access to that capacity.

Build Resilience Before Conditions Change

A transportation partner with both asset-based and brokerage capabilities can help match shipments with appropriate capacity solutions. Depending on the lane and product, options may include:

• Dedicated or contracted capacity
• Brokerage support
• Private or controlled fleet resources
• Team or expedited service
• Intermodal transportation when timing and product requirements allow

Strengthening Your Transportation Strategy

The goal is to identify the lanes with the least flexibility and plan for them early.

1. Identify lanes and materials where transportation failure would have the greatest operational impact.
2. Confirm your transportation partner can provide qualified primary and backup capacity.
3. Review fuel-surcharge terms and how quickly they respond to diesel price changes.
4. Share realistic forecasts and production changes with transportation partners early.
5. Define escalation procedures, communication expectations, and recovery options before disruptions occur.

Reduce Risk Before Conditions Change

Freight markets and diesel prices will continue to change. Manufacturers cannot control those shifts, but they can reduce risk by focusing on:

• Carrier qualification
• Freight lane planning
• A mix of capacity options
• Shipment visibility and clear communication

For critical shipments, the lowest freight rate is almost never the lowest-risk choice. Reliable capacity can help protect production, product quality, and customer commitments. Waiting until the market tightens may leave fewer options at a higher cost.

For critical materials, the greater concern is whether changing market conditions will limit access to qualified transportation capacity.

The most effective time to evaluate and secure the right capacity is before conditions make it more difficult.
