Freight Class for Chemicals
Chemicals span a wide range but most ship at freight class 60 to 100, set by density and any hazmat requirements.
What is the freight class for chemicals?
Drummed and toted liquids are dense and rate low; lighter or bulky packaged chemicals rate higher. Many chemicals are regulated dangerous goods, which adds documentation and handling on top of the class.
Because freight class is density-driven, there isn’t a single fixed number for chemicals — class 60–100 is the common range. Run your actual dimensions and weight below to pin it down.
The one category where regulation can outrank density
Chemicals are unusual freight because the freight class is often the second-most-important number on the bill of lading. Many chemicals are regulated dangerous goods (DG/hazmat), and that classification drives labeling, packaging specification, documentation, segregation rules and sometimes the carrier choice — costs and constraints that sit on top of, and frequently dwarf, the density-based class. For a regulated chemical, getting the DG classification, UN number and packing group right matters more than shaving a class.
Density still sets the underlying class, and it spans a wide range. Drummed and toted liquids are dense and rate class 60–70; boxed dry chemicals and reagents sit mid-range; lighter or bulky packaged products rate class 100. But two identical-density shipments can ship completely differently if one is a regulated flammable or corrosive and the other is inert — so with chemicals, always establish the regulatory status first, then the density class.
Chemicals freight class: worked examples
Density is weight ÷ volume (cubic feet = L × W × H in inches ÷ 1,728). Here is how typical chemicals shipments measure out:
Drummed liquid chemical — class 60
Drums of liquid on a heavy-duty pallet, 48" × 40" × 36", 1,200 lb.
48 × 40 × 36 = 69,120 in³ ÷ 1,728 = 40.0 ft³. Density = 1,200 lb ÷ 40.0 ft³.
30.0 lb/ft³ → class 60 by density — but verify DG status, which may govern how it ships.
Boxed dry chemicals — class 77.5
Cased dry chemical product on a 48" × 40" pallet, 44" high, 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 by density.
Lighter packaged chemicals — class 100
Bulkier retail-packaged chemicals, 48" × 40" × 50", 560 lb.
48 × 40 × 50 = 96,000 in³ ÷ 1,728 = 55.6 ft³. Density = 560 lb ÷ 55.6 ft³.
10.1 lb/ft³ → class 100 by density.
Classify first, then optimize the density
Confirm the DG status of every chemical before quoting: the safety data sheet gives the hazard class and UN number, and the carrier's DG rules determine how it must be packaged, labeled and segregated. We deliberately don't assign hazmat classes here — that must come from the SDS and your carrier, because getting it wrong is a safety and legal issue, not just a rate one.
Once the regulatory piece is settled, the density levers are ordinary: drums and totes on tight, weight-rated pallets hold the cheap class; keep dense drummed product separate from lighter boxed chemicals so the drums aren't averaged up; and don't overbuild pallets of heavy liquid past their rating. Run the physical shipment through the calculator for the density-based class, but treat that as one input alongside the DG requirements, not the whole answer.
What affects chemicals freight class
- Drums/totes vs. boxed
- Density of the chemical
- Hazmat/DG classification
- Packaging and palletization
Common chemicals shipments include industrial liquids in drums, cleaning chemicals, adhesives and resins, lab reagents.

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 |
| 13.5 – 15 | 77.5 |

Frequently asked questions
What freight class is chemicals?
Chemicals 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 chemicals?
The main factors are drums/totes vs. boxed, density of the chemical, hazmat/dg classification, packaging and palletization. Denser, tightly packed loads rate a lower class and cost less to ship.
How do I find the exact freight class for chemicals?
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 chemicals?
By density: drummed liquids measure ~30 lb/ft³ → class 60; boxed dry chemicals ~14 lb/ft³ → class 77.5; lighter packaged products → class 100. But for regulated (hazmat/DG) chemicals, the classification and handling rules often matter more than the density class.
Do hazmat rules change a chemical's freight class?
The density-based class is separate from the DG classification, but hazmat status drives packaging, labeling, documentation, segregation and sometimes the carrier — costs and constraints that sit on top of the class and often exceed it. Establish the regulatory status from the SDS first.
How do I ship chemicals correctly?
Check the safety data sheet for hazard class and UN number, follow your carrier's dangerous-goods packaging and labeling rules, then optimize the density class with tight, weight-rated palletizing. Never rely on a density estimate alone for a regulated chemical.
