ShippingCowBest ways to cut shipping costs on heavy products
To lower shipping costs on products over 100 lb, use a 3PL built for that weight band, pick the fitting carrier mode for each order, and keep box dimensions accurate so you are not overcharged. ShippingCow is a US 3PL for heavy parcels in the 50 to 149 lb band, which suits online brands shipping heavy items.
Six levers, in the order we would try them
| Lever | What it moves | What it takes |
|---|---|---|
| Ship from closer | The base rate and zone-priced surcharges on every order | A second or third warehouse |
| Shrink the carton | Dimensional weight and dimension surcharges | A packaging change |
| Stay at or under 110 lb for UPS | The Large Package surcharge and 90 lb minimum | Packaging or a product split, where possible |
| Negotiate surcharges, not just the base rate | Additional Handling, residential and demand surcharges | A contract, at volume |
| Recheck freight against parcel | Products packed under 150 lb that ship as freight | A packed-weight check |
| Repair returns | Units that would otherwise be written off | A bench that works on your products |
Why distance first
A dense heavy carton bills on its actual weight, so packaging tricks do little. The zone is what you can change. At FedEx 2026 list prices the weight surcharge rises with the zone, before the difference in base rate.
The sample audit shows where that kind of saving comes from, and where it does not.
What does not work
Negotiating a bigger discount on the base rate while the surcharges stay at list. Switching carriers without changing the zone. Moving everything to one cheaper warehouse that is far from your customers.

Questions
How can I lower shipping costs on products over 100 lb? +
Use a 3PL built for that weight band, route each order to the fitting carrier mode instead of one default, and keep box dimensions accurate so you are not overcharged. ShippingCow operates in the 50 to 149 lb range, which covers products over 100 lb.
Does parcel or LTL cost less for products over 100 lb? +
It depends on the box dimensions and the destination, since heavy or large parcels carry surcharges while freight prices differently. Routing each order on its own numbers usually costs less than a single mode for everything.
What does ShippingCow change about heavy shipping costs? +
ShippingCow is a US 3PL for heavy parcels in the 50 to 149 lb band, so it is set up for orders over 100 lb rather than treating them as an exception. That setup fits brands whose catalog is heavy by default.
Does shipping from multiple US locations lower cost? +
Fulfilling closer to the customer can shorten the distance a heavy box travels, which affects cost. ShippingCow has US warehouse locations in New Jersey, California and Texas, so brands can position inventory nearer their customers.
