Freight Class Explained
Bulk caster lots usually ship by freight, not parcel. Understanding freight class helps you read a delivered cost and avoid surprises. Here is the short version for buyers.
What freight class is
Freight class is a standardized code (the NMFC system) that carriers use to price less-than-truckload (LTL) shipments. It is driven mainly by density (weight relative to size), along with handling, stowability, and liability. Denser, easier-to-handle freight gets a lower class and a lower rate.
Why caster lots ship LTL
A pallet of casters or wheels is heavy and palletized, which makes it freight rather than parcel. Parcel carriers cap out on weight and dimensions, so once a lot crosses that threshold it moves to LTL freight on a pallet or in a crate.
What affects your delivered cost
- Weight and pallet count of the lot.
- Origin and destination, including distance and lane.
- Accessorials: liftgate, residential delivery, inside delivery, or limited-access locations add cost.
- Class, assigned from the commodity and its density.
How Overstock Casters shows freight
Every listing shows its freight method up front: parcel-eligible for small quantities, a fixed or estimated freight cost, a freight quote you request before paying, buyer-arranged freight, or local pickup. For oversized or mixed lots, use Request a Freight Quote for a delivered total before you commit. See the full shipping policy.
Buyer tips
- Give an accurate delivery address and note if a liftgate or residential delivery is needed.
- Inspect the shipment at delivery and note any damage on the bill of lading before signing.
- For repeat or large-volume buying, ask about freight and bulk orders.
