When you're mailing heavy boxes, sending packages that weigh more than 50 pounds or exceed standard parcel dimensions. Also known as heavy freight shipping, it’s not just about sticking on a label and dropping it off. You’re dealing with logistics that demand real planning—weight, size, carrier limits, and handling rules all play a part.
Most couriers treat heavy boxes, packages over 50 lbs or 100 lbs depending on the carrier. Also known as oversized parcels, they require special handling and pricing differently than regular mail. It’s not just about the distance. The courier pricing, how shipping companies calculate costs based on weight, dimensions, zone, and service level. Also known as parcel rate structure, it’s the system that determines what you pay system adds fees for weight overages, dimensional weight, and fuel surcharges. A 70-pound box might cost twice as much as a 30-pound one—even if it’s the same distance—because it takes more fuel, stronger equipment, and extra labor to move it. And if your box is bulky but light? That’s dimensional weight, and it can surprise you. Carriers measure volume and charge based on whichever is higher: actual weight or dimensional weight.
Not all couriers handle heavy boxes the same way. Some refuse anything over 70 lbs. Others charge extra for lift-gate delivery or residential pickup. That’s why door-to-door delivery, a service where the carrier picks up from your location and drops off at the recipient’s front door. Also known as last-mile delivery, it’s essential for personal or business shipments without warehouse access isn’t automatic. You have to ask. If you’re shipping a piano, a large piece of furniture, or industrial equipment, you might need a freight service, not a standard courier.

Compare quotes from at least two providers. And always ask: Does this include insurance? Will they lift it off the ground? Do they need a loading dock? These questions save you from delays, extra charges, or damaged goods.
