Managing the impact of General Rate Increases in parcel shipping

Every year, carriers announce a general rate increase. The headline percentage circulates quickly, budgets get revisited, and teams brace for higher shipping costs.

Then invoices arrive, and the impact rarely looks uniform. Some shipments rise sharply. Others barely change. In a few cases, cost increases in places teams were not watching closely.

A general rate increase, or GRI, is predictable. Its effect on specific shipping operations are not. Understanding why requires looking beyond the headline number and into how rates interact with contracts, packaging, service selection, and fulfillment decisions.

‍

What is a General Rate Increase?

A general rate increase, or GRI, is an annual update carriers apply to their published parcel rate structures. These changes typically take effect at the start of the year and adjust base transportation rates across services, weights, and zones.

Although announced as a single percentage, a GRI is not applied evenly. Rate tables are recalibrated by service level and distance, minimum charges are updated, and zone pricing shifts. As a result, shipments are affected differently depending on how far they travel and which services are used.

Historically, GRIs have been announced in the mid–single-digit range, often around 5-7% on published base rates. That figure provides context, but it does not reflect the actual increase most shippers experience. Final cost is shaped by contracts, accessorials, dimensional pricing, and fulfillment decisions layered on top of those rates.

A GRI applies to published rates, not final shipping cost. It does not reset negotiated discounts or change how shipments are packed, routed, or fulfilled. Those factors already exist in the network, and a rate increase simply magnifies their effect.

What does and does not change with a GRI

Understanding the boundary of a GRI helps separate true rate impact from existing inefficiencies. While the announced increase is often discussed as a single change, its effects are spread across specific components of the rate structure, while other elements remain untouched.

Base rates

Base transportation rates are updated annually by service level. Ground, air, and time-definite services each receive new pricing tables, often with different adjustments by weight break and zone. These changes form the core of every GRI.

Zone rates

Zone-based rate tables are recalibrated as part of a GRI. As distance increases, the impact of higher base rates becomes more pronounced. Long-haul shipments typically feel these changes more quickly than local or regional moves.

Minimum charges

Service-level minimum charges are also updated each year. Even modest increases here can materially affect lightweight shipments that consistently price at the floor.

Contracted discounts

Contracted discounts do not reset when a GRI takes effect. Negotiated incentives, earned discounts, and service-specific agreements remain in place unless renegotiated separately. While discounts may change over the life of a contract, they are not automatically adjusted as part of an annual rate increase.

Accessorials

Accessorial categories remain in effect under the same rules after a GRI. Residential delivery, fuel surcharges, delivery area fees, and handling charges continue to apply. Although their structure does not change because of a GRI, rising base rates often make these fees account for a larger share of total shipping cost.

Fulfillment workflows

Fulfillment workflows do not change with a GRI. How orders are packed, where they ship from, and which services are selected continue to influence cost in the same way they did before the increase. Because these decisions remain constant, any inefficiencies already present in the operation tend to stand out more once higher rates are applied.

Again, a general rate increase does not correct inefficiencies. It amplifies what is already happening in the shipping network.

Why the same GRI feels different for every shipper

Two companies can face the same announced increase and see very different results on their invoices. In this way, a GRI functions like a stress test. It highlights where cost pressure already exists and reveals where the network is already stretched.

Order geography

Order geography reflects where customers are placing orders. As demand shifts toward new regions, zones change even if fulfillment locations stay the same. When customer demand moves farther from existing distribution centers, teams can use order data to identify growing regions that may need different service or fulfillment strategies.

Service mix

Service mix matters as well. Over time, many operations drift toward faster services to meet delivery expectations. Those services often carry higher rate adjustments year over year. This is a signal to reassess whether current service selections still align with delivery promises and customer expectations.

Dimensional exposure

Dimensional exposure compounds quietly. As packaging standards loosen or product assortments change, more shipments cross into higher dimensional weight brackets. A GRI magnifies that shift. Regularly reviewing box usage and dimensional trends can help identify where packaging changes are driving unnecessary cost increases.

Fulfillment location

Fulfillment location alignment determines where shipments originate. Even with stable demand, inventory placement and routing rules influence how far packages travel. Reviewing how orders are routed across warehouses can reveal opportunities to shorten shipping distances without changing customer demand.

The cost drivers that shape GRI impact

Base rates are only part of the story. Several secondary cost drivers determine how strongly a GRI is felt. 

Percent-based accessorials

Many accessorial fees scale as a percentage of base transportation rates or are applied on a per-shipment basis. As base rates rise, these fees account for a larger share of total shipping cost.

Packaging selection

Oversized boxes, inconsistent carton selection, and unused space all influence dimensional pricing and increase the likelihood that shipments move into higher-cost tiers.

Peak season

Peak season compounds existing cost pressure. Higher volume spikes, tighter delivery windows, and increased reliance on premium services amplify the impact of annual rate changes.

Without visibility into how these elements interact, teams often focus on the announced percentage and miss the real drivers of cost growth.

Viewing a GRI as a signal, not just a cost

Instead of treating a general rate increase as a one-time event, it can be more useful to view it as an indicator of where to adjust your strategy or workflow.

Repeated increases in the same zones point to geographic misalignment. Services that grow more expensive year over year may no longer align with delivery requirements. Packaging-related increases often indicate process drift on the warehouse floor.

Seen this way, a GRI highlights structural patterns. It shows where demand, fulfillment decisions, and pricing mechanics are slowly moving out of alignment.This perspective shifts the conversation from reacting to rate changes toward understanding structural patterns.

Preparing for a General Rate Increase without renegotiation

Renegotiating contracts is one option to prepare, but it is not the only lever available. Many teams reduce the impact of a general rate increase by focusing on areas they already control.

Review historical shipment patterns

Analyzing prior years by zone and service reveals where increases tend to land. Long-distance lanes and premium services often show repeat exposure.

Audit invoices and billing trends

Invoice audits surface compounding errors that become more noticeable as rates rise. This prevents unrelated billing issues from being mistaken for GRI impact.

Tighten packaging standards

Standardizing cartons and reducing unused space lowers dimensional exposure. Even small adjustments can offset part of an annual increase across high-volume shipments.

Reassess service selection rules

Service logic often drifts toward faster options over time. Revisiting these rules ensures lower-cost services are used when they still meet delivery expectations.

Use past GRIs to plan ahead

General rate increases follow a predictable rhythm. Modeling scenarios using historical year-over-year data allows teams to test packaging, routing, or service changes before new rates take effect

‍

Closing thoughts

Preparation turns a predictable event into a manageable one. General Rate Increases are unavoidable, but their impact is not uniform.

Teams that understand how GRIs interact with their order geography, service mix, packaging standards, and fulfillment decisions will be able to plan with intention instead of reacting after costs rise. By treating GRIs as signals rather than surprises, operations and finance leaders can adjust workflows, tighten controls, and absorb annual increases without allowing shipping costs to grow unchecked. 

The goal is to understand general rate increases in the context of your own operation so you can plan for them, absorb them efficiently, and limit unnecessary cost growth year over year.
