NMFC Class 60 — Auto Parts
Automotive batteries are dense, heavy items that ship at freight class 60–65. Lithium batteries may require hazmat classification.
Typical class: 60 · Density: 30–50 lbs/cu ft
Shipment Dimensions (inches)
| Class | Density (lbs/cu ft) | Description |
|---|---|---|
| 50 | 50+ | Heaviest, most dense freight |
| 55 | 35–50 | Very dense freight |
| 60 | 30–35 | Dense freight |
| 65 | 22.5–30 | Moderately dense |
| 70 | 15–22.5 | Average density |
| 77.5 | 13.5–15 | Slightly below average |
| 85 | 12–13.5 | Below average density |
| 92.5 | 10.5–12 | Light freight |
| 100 | 9–10.5 | Light freight |
| 110 | 8–9 | Light, bulky freight |
| 125 | 7–8 | Bulky freight |
| 150 | 6–7 | Very bulky freight |
| 175 | 5–6 | Very light, bulky |
| 200 | 4–5 | Extremely light |
| 250 | 3–4 | Extremely light, high value |
| 300 | 2–3 | Low density, high handling |
| 400 | 1–2 | Very low density |
| 500 | 0–1 | Lowest density, highest cost |

NMFC Class 60 — packaging, handling, and freight class details
Automotive batteries are dense, heavy, and carry regulatory requirements that most other freight does not. Johnson Controls (now Clarios), East Penn Manufacturing, and Exide Technologies are the dominant domestic manufacturers, supplying auto parts retailers, dealerships, and fleet accounts through established distribution networks. The replacement cycle for automotive batteries averages 3–5 years, generating a steady replacement market of 150+ million batteries annually in the US.
Lead-acid batteries ship at Class 60–65 due to their high density. A standard 12-volt group 24 battery weighs 40–50 lbs and occupies 0.8–1.0 cubic feet — that is 45–55 lbs/cuft, which would technically qualify for Class 50, but NMFC classification accounts for the hazmat handling premium and classifies them at 60–65. A full pallet of 40–50 automotive batteries runs 1,800–2,200 lbs on a 48x40 base.
The regulatory dimension separates battery freight from most other auto parts. Lead-acid batteries contain sulfuric acid, making them Class 8 Corrosive hazardous materials under DOT regulations. Proper UN-marked packaging, hazmat placarding on the trailer, shipping papers with the correct UN number (UN2794 for wet batteries), and an emergency response number on the bill of lading are all required. Carriers without hazmat endorsement cannot transport wet-cell lead-acid batteries. Batteries must be shipped upright to prevent acid leakage.
Lithium-ion automotive batteries (12V lithium, EV battery packs) are categorized differently and carry more complex regulations under UN3480 or UN3481, depending on state of charge. EV battery packs weighing hundreds of pounds require specialized handling and may need ground-only shipping restrictions. Rate context: battery freight pays a modest hazmat premium over standard commodity rates. Carriers need to verify their hazmat certification is current before accepting any battery loads.
