When you look at your UPS invoice and the total is higher than the rate quoted at label creation, UPS fuel surcharges are almost always a contributing factor. For Shopify merchants shipping at any meaningful volume, these percentage-based additions to base rates represent a real and recurring cost that changes every week. Understanding how UPS fuel surcharges work, how they’re calculated, which services they apply to, and how frequently they change is the first step toward building accurate shipping margins into your Shopify store.

What Are UPS Fuel Surcharges and Why Do They Exist?
UPS fuel surcharges are additional charges added to the base transportation rate of every eligible UPS shipment to cover the carrier’s fuel operating costs. Rather than baking fuel costs into base rates, which would require constant repricing, UPS applies a variable percentage on top of the base rate that adjusts automatically as fuel prices rise and fall.
If you have a UPS account number, the fuel surcharge will be included on your weekly bill. If you are an occasional UPS customer and do not receive a weekly bill, a fuel surcharge will be included in your charges.
For Shopify merchants, this means UPS fuel surcharges are not optional, not negotiable at the standard level, and not fixed. They appear on every invoice and move independently of base rates. A merchant who built their shipping margins around a 20% surcharge in one quarter may find that figure has shifted meaningfully by the next. For a broader view of what drives UPS costs, the cheap UPS shipping guide for Shopify covers how surcharges fit into the overall cost structure.
How UPS Calculates Fuel Surcharges: The Index-Based Model
UPS uses an index-based surcharge model, with the surcharge tied to fuel-price data published by the U.S. Energy Information Administration (EIA).
For Ground services:
- The U.S. Ground Domestic and UPS Ground Saver Fuel Surcharge uses an index-based surcharge that is adjusted weekly. Changes to the surcharge will be effective on Monday of each week.
- The surcharge will be based on the National U.S. Average On-Highway Diesel Fuel Price as most recently released by the U.S. Energy Information Administration (EIA), rounded to the nearest cent.
For Domestic Air services:
- The Domestic Air Fuel Surcharge is also adjusted weekly and will be based on the U.S. Gulf Coast (USGC) price for kerosene-type jet fuel as most recently released by the EIA, rounded to the nearest cent.
Notes:
- Regardless of the EIA-released average fuel prices or the published tables, the Fuel Surcharge percentages posted on the 90-Day Fuel Surcharge History table in effect on the date of shipment will apply.
- The 90-Day Fuel Surcharge History table is typically updated once per week with the most current Fuel Surcharge percentages.
- The practical implication for Shopify merchants: Fuel surcharge rates, thresholds, and methods of calculation are subject to change without prior notice.
UPS Fuel Surcharge Types by Service Category in Shopify
UPS applies different fuel surcharge schedules depending on the service used. There are four distinct surcharge types for domestic and international package shipping:
1. U.S. Ground Domestic and UPS Ground Saver Fuel Surcharge
Indexed to the National U.S. Average On-Highway Diesel Fuel Price. Applied weekly each Monday. Recent historical rates have ranged from approximately 18% to 26% depending on diesel prices.
2. Domestic Air Fuel Surcharge
Indexed to U.S. Gulf Coast (USGC) kerosene-type jet fuel prices. Applied weekly each Monday. Air surcharges typically run higher than Ground surcharges due to the greater fuel intensity of air transport. Recent historical rates have ranged from approximately 24% to 30%.
3. International Air-Export and International Air-Import Fuel Surcharge
The International Air-Export and International Air-Import Fuel Surcharge is indexed to the U.S. Gulf Coast price for kerosene-type jet fuel as most recently released by the EIA. UPS adjusts the surcharge weekly, with changes taking effect every Monday. Export and import surcharges operate on separate rate tables.
4. International Ground Export Import Fuel Surcharge
The International Ground Export Import Fuel Surcharge is based on the National U.S. Average On-Highway Diesel Fuel Price and adjusted weekly, effective on Monday of each week. This applies to UPS Standard services to Canada and Mexico.
For Shopify merchants operating cross-border, understanding the distinction between domestic and international surcharge types matters when projecting landed shipping costs. The UPS international shipping guide for Shopify covers how these costs interact with duties and customs fees for cross-border orders.
Which UPS Services Are Affected by Fuel Surcharges on Shopify?
UPS fuel surcharges apply across virtually all UPS package services. Here is the complete breakdown by surcharge type:
U.S. Ground Domestic and UPS Ground Saver Fuel Surcharge applies to:
UPS Ground, UPS Ground with Freight Pricing, UPS Hundredweight Ground Service, UPS Ground Saver, and UPS Basic.
The U.S. Ground Domestic Fuel Surcharge does not apply to UPS Ground packages originating in the 48 contiguous United States when subject to Retail rates.
Domestic Air Fuel Surcharge applies to:
UPS Next Day Air Early, UPS Next Day Air, UPS Next Day Air Saver, UPS 2nd Day Air A.M., UPS 2nd Day Air, UPS 3 Day Select, and UPS Hundredweight Air services.

International Ground Export Import Fuel Surcharge applies to:
UPS Standard to/from Canada and UPS Standard to/from Mexico.
For Shopify merchants comparing which UPS services to offer at checkout, understanding which fuel surcharge tier applies to each service helps explain why the same package can cost meaningfully different amounts across service levels even after base rate differences. The UPS shipping services guide for Shopify maps out the full service lineup alongside key cost considerations.
How Fuel Surcharges Stack with Other UPS Charges in Shopify
UPS fuel surcharges do not apply only to the base transportation charge. They apply more broadly across shipment costs, which Shopify merchants often overlook when estimating total per-package cost.
Fuel surcharges apply to all domestic and international transportation charges and certain other accessorial, value-added, and other charges.
This means that when additional charges apply to a shipment such as residential delivery surcharges, address correction fees, or additional handling fees, the fuel surcharge percentage is also applied to those additional charges, not just the base rate.
In practical terms for a Shopify order:
- Base Ground rate: $12.00
- Residential delivery surcharge: $5.40
- Combined base before fuel surcharge: $17.40
- Fuel surcharge (at ~20%): $3.48
- Total: $20.88
A merchant who only applied the fuel surcharge to the base rate would underestimate the total cost. This compounding effect is particularly significant for merchants shipping predominantly to residential addresses. To understand how residential delivery charges interact with your rate setup, the UPS rates display guide for Shopify covers how these components combine at checkout.
Display Accurate UPS Rates in Shopify with the PH Multi-Carrier Shipping Label App
The variable nature of UPS fuel surcharges is one of the strongest arguments for using live rate integration rather than flat rates on Shopify.
The PH Multi-Carrier Shipping Label App by PluginHive connects your UPS account directly to Shopify and pulls live UPS rates at checkout, which automatically incorporate the current week’s fuel surcharge percentage.
Here’s how this helps Shopify merchants manage UPS fuel surcharges:
- Live rate fetching at checkout: Every time a customer reaches the shipping step, the app fetches current UPS rates from your connected UPS account. Because UPS calculates the fuel surcharge into the rate returned by its API, the checkout price always reflects the actual surcharge in effect that week.
- Automatic surcharge pass-through: The app does not require merchants to manually update fuel surcharge percentages. As the index shifts each Monday, the live rates adjust automatically without any action from the merchant for all services. Additionally, you can also adjust these charges based on margins.
- Service-level rate display: Customers see rates for the specific UPS services you’ve enabled — Ground, 2nd Day Air, and Next Day Air — each with the current fuel surcharge already included, allowing them to make an informed choice at checkout.
- Accurate label cost matching: Because the same live rate API is used both at checkout and at label generation, the cost shown to the customer and the cost billed to your UPS account remain aligned, preventing margin erosion from surcharge movement between order placement and label creation.
For Shopify stores also managing the return side of operations, the UPS return labels guide for Shopify covers how live rate accuracy extends to inbound return shipments.
Conclusion
Managing shipping margins on Shopify requires constant oversight, with weekly UPS fuel surcharges driving significant cost variations. Because these percentage-based fees apply to both base rates and extra charges like residential surcharges, ignoring them directly eats into your profits.
Static flat rates force you to constantly update prices or swallow the difference. By using live-rate tools like the PH Multi-Carrier Shipping Label App, you automatically pass real-time UPS fuel surcharges to customers at checkout, protecting your margins, keeping pricing accurate, and eliminating billing surprises.
