Freight Class for Electrical Supplies
Electrical supplies usually ship at freight class 60 to 100, depending on the mix of dense and light items.
What is the freight class for electrical supplies?
Wire spools, conduit and metal components are dense and rate low; lighter fixtures, panels and boxed devices rate higher. Palletized, full cases keep the class down.
Because freight class is density-driven, there isn’t a single fixed number for electrical supplies — class 60–100 is the common range. Run your actual dimensions and weight below to pin it down.
Dense copper, light devices, valuable either way
Electrical supplies split by weight per box like tools and auto parts. Wire and cable are the dense anchor — copper and aluminum wound tight on spools or in coils are heavy and compact, rating class 60–65. Boxed devices, panels, breakers and fixtures are lighter, packaged with void for protection, rating class 85–100. A contractor's order mixes both, and the blend sets the class.
Wire adds a dimension most freight doesn't: value. A pallet of copper wire is worth a lot and is a known theft target, so security and coverage can matter as much as the class — copper's price makes a spool pallet a very different risk than a pallet of plastic boxes. That value consideration rides alongside the density class, not instead of it.
Electrical Supplies freight class: worked examples
Density is weight ÷ volume (cubic feet = L × W × H in inches ÷ 1,728). Here is how typical electrical supplies shipments measure out:
Copper wire spools — class 65
Wire spools secured on a 48" × 40" pallet, 40" high, 1,100 lb.
48 × 40 × 40 = 76,800 in³ ÷ 1,728 = 44.4 ft³. Density = 1,100 lb ÷ 44.4 ft³.
24.8 lb/ft³ → class 65 — dense wound copper anchors the cheap end.
Boxed breakers and panels — class 100
Cartoned electrical devices on a 48" × 40" pallet, 50" high, 500 lb.
48 × 40 × 50 = 96,000 in³ ÷ 1,728 = 55.6 ft³. Density = 500 lb ÷ 55.6 ft³.
9.0 lb/ft³ → class 100 — protective-packaged devices are the light end.
Mixed wire and devices — class 77.5
A blended contractor pallet of wire and boxed devices, 48" × 40" × 44", 700 lb.
48 × 40 × 44 = 84,480 in³ ÷ 1,728 = 48.9 ft³. Density = 700 lb ÷ 48.9 ft³.
14.3 lb/ft³ → class 77.5 — the dense wire pulled the blend down from the devices' class.
Keep the copper tight and separate
Concentrate the dense wire on its own tight, weight-rated pallets to hold class 60–65 — spools and coils are heavy, so these units weigh out low and don't need height. Band securely; a shifting spool pallet is both a damage and a handling hazard. Keep light boxed devices and fixtures on their own units rather than blending them with wire, where their air drags the dense copper's class up.
For the boxed side, the usual bulky-freight rules apply: master cartons over single retail boxes, full square pallets, molded protection over loose fill for panels and breakers. Given copper's value, price secure or insured handling for wire-heavy shipments deliberately — on a full spool pallet the theft and loss exposure can exceed any rate difference. Run the actual mix through the calculator; a blended electrical pallet rarely sits where a single component's class would suggest.

How freight class is calculated (density scale)
Freight class is set by density = weight (lb) ÷ volume (ft³). Higher density → lower class → typically lower cost. Volume here is L × W × H × quantity.
| Density (lb/ft³) | Class |
|---|---|
| 50+ | 50 |
| 35 – 50 | 55 |
| 30 – 35 | 60 |
| 22.5 – 30 | 65 |
| 15 – 22.5 | 70 |

Frequently asked questions
What freight class is electrical supplies?
Electrical Supplies typically ships at freight class 60–100. The exact class is set by density — weight divided by volume — so packaging and dimensions can move it within that range.
What affects the freight class of electrical supplies?
The main factors are wire/metal density vs. fixtures, spools vs. boxed devices, packaging, palletization. Denser, tightly packed loads rate a lower class and cost less to ship.
How do I find the exact freight class for electrical supplies?
Measure your shipment and divide weight by volume to get density, then match it to the NMFC scale — the calculator above does this. Confirm the final class and NMFC item number with your carrier before booking.
What freight class are electrical supplies?
Dense wire and cable spools measure ~24–28 lb/ft³ → class 60–65; boxed devices, breakers and fixtures are lighter at ~9 lb/ft³ → class 100. A mixed pallet lands between — run the actual wire-to-devices blend.
Should copper wire ship separately from devices?
Usually yes. Dense wire holds class 60–65 on its own tight pallet, while blending it with light boxed devices averages the density up. Separating them also isolates the high-value copper for secure handling.
Does the value of copper wire affect shipping?
Not the density class directly, but a pallet of copper wire is valuable and a theft target, so secure or insured handling is worth pricing deliberately. On wire-heavy shipments the loss exposure can exceed the rate difference between classes.
