Freight Class for Refrigerators
A refrigerator in its factory carton usually ships at freight class 92.5 on the current NMFC scale. A top-freezer unit measured 10.3 lb/ft³, which is class 92.5. Re-crating a built-in unit with extra room dropped it to 8.8 lb/ft³, which is class 100. The carton and crate set the class more than the model does, and some appliances have their own NMFC item, so confirm with your carrier.
The appliance that ships itself
Refrigerators are unusually consistent freight because the manufacturer already solved the packaging problem: the factory carton — corner posts, top cap, film — is engineered to protect a specific unit at minimum material, which also means near-minimum cube. That's why most residential fridges in factory packaging land predictably in the narrow 92.5–100 band, and why the best shipping decision is usually to leave the factory carton alone.
The spread inside the band follows the airspace inside the cabinet. A top-freezer unit is a relatively tight steel box; a counter-depth French-door with ice systems and wider clearances carries more enclosed air per pound and drifts toward class 100. Commercial units cut both ways — glass-door merchandisers are heavy but tall, undercounter units are compact and dense — so quote commercial pieces individually rather than off the residential pattern.
Worked examples
Measured as the carrier will: the outside of the carton or crate, the skid under it, and the total weight.
Top-freezer refrigerator, factory carton — class 92.5
A boxed top-freezer unit, 30" × 32" × 68", 390 lb.
30 × 32 × 68 = 65,280 in³ ÷ 1,728 = 37.8 ft³. Density = 390 lb ÷ 37.8 ft³.
10.3 lb/ft³ → class 92.5 on the current NMFC scale — typical for a factory-packaged unit.
Four mini fridges on one pallet — class 92.5
Compact fridges boxed and palletized two-by-two, 48" × 40" × 38", 460 lb total.
48 × 40 × 38 = 72,960 in³ ÷ 1,728 = 42.2 ft³. Density = 460 lb ÷ 42.2 ft³.
10.9 lb/ft³ → class 92.5. Shared footprint, best class in the range.
A built-in unit re-crated with clearance — class 100
A 560 lb panel-ready fridge in a site-protection crate, 40" × 32" × 86".
40 × 32 × 86 = 110,080 in³ ÷ 1,728 = 63.7 ft³. Density = 560 lb ÷ 63.7 ft³ = 8.8 lb/ft³.
8.8 lb/ft³ → class 100. The crate's clearance costs a class versus the factory carton.
Upright, strapped, and measured once
Refrigerators ship standing up — compressors and sealed systems don't tolerate lying down — which fixes the height dimension and makes the footprint the only variable you control. Skid the unit on its own base dimensions rather than centering one fridge on a full 48" × 40" pallet: the unused deck strip beside a 33-inch-deep carton is measured, billed air. Two units side-by-side filling a pallet earn their footprint honestly.
Re-crating is the class killer in this category. Built-in and panel-ready units often get wooden crates for site protection, and the clearance those crates add routinely drops density below the factory-carton figure — a class 92.5 unit re-crated with door-swing room can bill at 100 (the worked example above). When a crate is truly required, build it snug to the carton, and run both configurations through the calculator so the protection is a priced decision, not a surprise on the invoice.

Frequently asked questions
What freight class is a refrigerator?
Usually class 92.5 in the factory carton, and 100 if it is re-crated with extra clearance. Several compact fridges sharing one pallet can stay at 92.5 too. Measure the package as shipped, not the appliance's spec sheet.
What freight class is a refrigerator?
Residential units in factory cartons typically measure 8.5–11 lb/ft³ → class 92.5–100 on the current NMFC scale. Multiple compact units palletized together rate at the dense end; re-crated built-ins at the light end. Measure the shipped package, not the appliance spec.
Can a refrigerator ship lying down?
Plan on shipping it standing. Refrigerator makers generally ask for upright transport, so the height is fixed. What you can control is the footprint (a skid cut to the carton, not a bigger pallet) and any added crating.
Does the pallet under a fridge change the freight class?
Yes, when it's bigger than the carton. A fridge centered on a full 48" × 40" pallet bills the whole deck's footprint; a skid cut to the carton's base keeps the measured cube at the unit's true size. On one unit that gap can be a class.
