How to Ship Auto Parts via LTL Freight
Guide to shipping automotive parts and accessories on pallets. Covers freight class by part type, packaging for engines and body panels, fluid handling, and cost-saving tips for aftermarket and OEM parts.
Quick reference
Recommended packaging
Box individual parts in corrugated cartons with foam inserts. Stack cartons on a standard 48x40 pallet, interlocking layers for stability. For engines and transmissions, bolt to a skid or use an engine stand bolted to the pallet. Wrap body panels individually in foam or blankets. Shrink-wrap the full pallet with four or more layers.
Accessorials you may need
These are the most common accessorial services for auto parts shipments. Declare them at booking time — carriers that discover them on arrival bill more and back-date to the invoice. With Warp, every accessorial below is already included in the per-pallet rate.

Shipping tips for auto parts
- Drain engines, transmissions, and any fluid-containing parts completely. Residual fluids leak during transit and trigger hazmat charges.
- Ship body panels (hoods, fenders, bumpers) on edge, not flat. Edge orientation reduces flex damage and uses pallet space more efficiently.
- Interlock carton layers like bricks. Aligned stack seams create a weak point that collapses when other freight is stacked on top.
- Group small parts (bolts, brackets, sensors) in a single master carton instead of shipping loose. Loose small boxes get lost in LTL terminals.
Common mistakes to avoid
Mistake 1: Engines with residual oil are classified as hazmat. Drain completely, cap all ports, and mark "Fluids Drained" on the BOL.
Mistake 2: Body panels shipped flat without individual wrapping get scratched by the pallet surface. Always ship on edge with foam between panels.
Mistake 3: Small individual boxes (under 1 cubic foot) get lost in LTL terminals. Consolidate small parts into a master carton before palletizing.
Freight class for auto parts
Auto parts range from class 60 to class 150 depending on density and type. Heavy, dense parts like engines (class 60-70), brake rotors, and axles ship at low classes. Body panels, bumpers, and trim pieces are lighter per cubic foot and ship at class 100-150. Mixed pallets of assorted parts are classified by the highest-class item on the pallet unless each is individually identified on the BOL.
Packaging auto parts for LTL
Automotive parts come in every shape and size, so packaging varies. Engines and transmissions should be bolted to a skid or engine stand, then secured to the pallet. Body panels should be stood on edge with foam sheets between each panel, secured by banding. Small parts (sensors, brackets, hardware) go in individual poly bags inside a master carton. The master carton goes on the pallet. Every carton should be labeled with contents and part numbers for accurate freight classification and easy inspection.
Auto Parts shipping FAQ
What freight class are auto parts?
Auto parts ship between class 60 and class 150. Heavy parts like engines, transmissions, and brake assemblies are class 60-85. Lighter items like body panels and trim are class 100-150. The exact class depends on the density of the palletized shipment.
Can I ship an engine via LTL?
Yes. Drain all fluids (oil, coolant, transmission fluid), cap all ports, and bolt the engine to a skid or engine stand. Mark "Fluids Drained" on the BOL. A drained engine typically ships at class 60-70.
How do I ship body panels without damage?
Stand panels on edge, not flat. Place foam sheets or moving blankets between each panel. Secure with cardboard edge protectors and banding. Ship on a standard pallet with shrink-wrap around the entire load.

LTL auto parts shipping costs $100-500 per pallet depending on distance, class, and weight. Dense engine pallets cost less per pound than bulky body panel pallets. Get an instant rate on Warp with your exact dimensions and weight.
