When shipping products, the carrier you choose doesn’t just affect delivery - it also directly influences packaging costs. Carriers like FedEx, UPS, and USPS each have specific policies that impact box dimensions, materials, and overall expenses. Here’s what you need to know:
- FedEx uses dimensional weight pricing, so oversized boxes for lightweight items can lead to higher costs. Specific packaging rules and surcharges for irregular packages can also drive up expenses.
- UPS recently updated its dimensional weight policy, rounding up fractional inches, which increases billable weight and costs. Surcharges for large or irregular packages are common.
- USPS offers flat-rate shipping and charges based on actual weight for most domestic shipments, making it more cost-effective for smaller packages. However, nonmachinable items may incur extra fees.
Each carrier has strengths and drawbacks. FedEx excels in specialized shipping but is costly. UPS is reliable but adds surcharges. USPS is budget-friendly for lightweight packages but less reliable for on-time delivery. Optimizing packaging to align with carrier rules can help reduce costs while maintaining product safety.
The Cheapest Way To Ship A Package – USPS Vs FedEx Vs UPS
1. FedEx
FedEx's pricing structure often drives up packaging costs for CPG brands, making it a key player in how these brands approach shipping and packaging strategies. The carrier's policies and requirements can significantly influence packaging decisions, frequently pushing brands to adapt to specific shipping guidelines.
Dimensional Weight Policies
FedEx uses dimensional weight pricing to calculate shipping costs. Essentially, if the dimensional weight - calculated by dividing the package's volume by 139 for domestic shipments - exceeds the actual weight, the shipping cost is based on the larger number. This can be a headache for brands shipping lightweight items in larger boxes. For instance, a product weighing just 4 oz, shipped in a 12″ × 8″ × 4″ box, would have a much higher dimensional weight, leading to inflated shipping costs. To navigate this, brands often turn to custom-sized packaging or rethink their packaging strategies altogether to minimize these charges.
Packaging Specifications and Surcharges
FedEx has strict packaging rules that can add to material costs and complicate design choices. If a package exceeds the maximum allowed dimensions, oversized surcharges kick in. Additionally, items that don't meet standard specifications may face extra handling fees. Products with irregular shapes or fragile items often require additional protective measures, such as extra padding or cushioning, to meet FedEx's guidelines - further driving up costs.
Cost Efficiency for CPG Brands
FedEx Ground does offer competitive rates for many shipments, but navigating their policies is critical to keeping costs in check. Sticking to FedEx's recommended box dimensions and packaging guidelines can help brands avoid unnecessary surcharges. While volume discounts and loyalty programs may benefit larger brands with high shipping volumes, smaller CPG brands often struggle to offset the added expenses caused by dimensional weight pricing and surcharges.
2. UPS
UPS presents unique cost challenges for businesses, particularly when it comes to packaging. Recent updates to their policies make it essential for brands to rethink their packaging strategies to manage rising expenses effectively.
Dimensional Weight Policies
On August 18, 2025, UPS introduced a policy change that directly affects how packaging costs are calculated. The carrier now rounds up every fractional inch in a package's length, width, and height when determining dimensional weight. This adjustment, which aligns with FedEx's approach, has been nicknamed the "rounding tax" because it increases the cubic volume and billable weight of packages.
The financial implications are significant. For example, a business shipping 2,500 packages per month could see an annual cost increase of $32,678 due to this rounding policy - without any growth in shipping volume. Additionally, under standard rate structures, ground shipping costs are expected to rise by about 6.2%, while overnight services could see a 9% increase.
UPS uses the formula (Length × Width × Height) ÷ divisor to calculate dimensional weight. The divisor is 139 for Daily Rates and 166 for Retail Rates. For instance, a package measuring 10.1″ × 8.1″ × 6.1″ would be rounded up to 11″ × 9″ × 7″, which significantly increases the billable weight, especially for lightweight products.
Packaging Specifications and Surcharges
UPS imposes several surcharges that can quickly add up for brands. These include Additional Handling, Over Maximum Size, and Large Package Surcharges, all of which depend on a package's dimensions, weight, or packaging type. Packages can weigh up to 150 lbs and measure up to 108 inches in length but must also meet specific girth requirements. Failure to comply with these standards can result in fees, delays, or reclassification into higher pricing tiers.
For businesses, precise measurements are crucial to avoiding unnecessary penalties and maintaining efficient operations.
Cost Efficiency for CPG Brands
UPS's dimensional weight pricing is designed to maximize vehicle space by discouraging oversized packaging. However, this approach places additional cost burdens on shippers. To stay competitive, brands need to focus on packaging optimization, accurate measurements, and strategic fulfillment planning.
Lightweight shippers are particularly affected by UPS's rounding policy. To counter these challenges, CPG brands should consider redesigning their packaging to fit within optimal dimensional weight parameters. Custom packaging solutions, like those offered by Paking Duck, can help reduce wasted space while still protecting products effectively.

3. USPS
The United States Postal Service (USPS) operates under a unique cost structure compared to private carriers. However, its evolving policies and specific packaging requirements can influence shipping expenses.
Packaging Specifications and Surcharges
USPS has clear rules on package size and weight. For Priority Mail, packages can weigh up to 70 lbs, with a maximum combined length and girth of 108 inches. The same weight limit applies to Ground Advantage services.
Additional surcharges come into play for nonmachinable items - those that are rigid, have clasps, strings, or uneven surfaces that can’t go through automated sorting systems. These fees vary depending on the service level.
USPS also has specific guidelines for packaging materials. While Priority Mail Express and Priority Mail include free packaging options, using your own packaging can sometimes lead to higher rates. This creates a balancing act for brands: saving costs with custom packaging versus potentially paying more in shipping fees. Understanding these rules is key to leveraging USPS's cost benefits.
Cost Efficiency for CPG Brands
Even with these restrictions, USPS provides cost-saving opportunities, especially for optimized shipments. Unlike FedEx and UPS, USPS typically charges by actual weight for domestic shipments, and its flat-rate boxes offer consistent pricing for packages up to 70 lbs.
For brands with national distribution, strategies like zone skipping can reduce both shipping times and costs. By consolidating shipments and using postal facilities closer to end customers, companies - such as subscription box services or direct-to-consumer brands - can streamline their logistics and save money.
Flat-rate and Regional Rate boxes from USPS also provide predictable pricing, especially when product dimensions align with the box sizes. Companies like Paking Duck specialize in custom packaging solutions that maximize flat-rate shipping efficiency and lower per-unit costs. Matching product dimensions to available box options is essential for protecting items while keeping costs in check.
For high-volume shippers, USPS’s Commercial Pricing programs unlock additional discounts. Brands meeting volume thresholds can access reduced rates on services like Priority Mail and Ground Advantage, making USPS an appealing choice as shipping operations grow.
Pros and Cons
Looking at the detailed carrier breakdown above, let's summarize the main trade-offs for CPG brands when it comes to packaging costs and logistics efficiency.
