When Freight Costs More Than the Machining
September 1, 2026
On a small machined part, freight is a line item nobody reads. On a heavy one it can exceed the machining, and it can decide which shops are worth asking in the first place.
It is also the part of a heavy order that is most often left until last, which is when it is most expensive.
What makes a load oversized
Four things, and you only need one.
Width. The first limit reached in practice. Once the load is wider than a standard trailer, it needs a permit and often an escort.
Height. Trailer height plus part height against bridges and overhead lines on the route.
Length. Extended or multi-axle trailers, and turning circles at each end.
Weight. Axle loading limits, bridge ratings and the crane at both ends.
Past any of these the shipment stops being a booking and becomes a project with a route survey, permits, a lifting plan and a date that cannot easily move.
The items that make up the cost
The trailer. Low loader, extendable or modular. Specialist equipment is not priced like a standard truck.
Permits. Per jurisdiction crossed, each with its own lead time. This is often the longest item, not the driving.
Escorts. Required on many oversized moves and priced per vehicle per day.
Route survey. On very large loads somebody drives the route first to check clearances and turns.
Lifting at both ends. Cranes, riggers and a lifting plan. The crane at the destination is frequently forgotten until the truck arrives.
Crating and packing. A crate for a three tonne machined part is a structure in its own right, designed around the lifting points and the centre of gravity.
Preservation. Machined surfaces rust. A part that spends three weeks on a ship needs protection.
Insurance. On a part worth more than the truck, worth reading the wording.
Why it changes which shop you pick
A shop 500 km away charging a higher hourly rate can land cheaper than one across an ocean, because freight and permits swamp the rate difference. On very heavy parts this reverses the usual logic of global sourcing completely.
It also changes lead time. An oversized move with permits can take longer to arrange than the finish machining takes to perform. See lead time on large machined parts.
This is why the delivery city or port belongs in the RFQ from the start, not in the purchase order at the end. It is one line and it changes the shortlist.
What to design in before the part is machined
Lifting points. Tapped holes for eyebolts, machined lugs, or clearly marked sling positions. They usually have to be machined or welded, so they belong on the drawing. Adding them to a finished part means handling and often re-preserving it.
Centre of gravity. Mark it. Riggers need it and so does the crating designer.
Support faces. Say which surfaces the part may rest on. A machined face taking the whole weight on a wooden crate bearer will be marked.
Protection for critical surfaces. Bores, seal faces and rail mounting strips. Covers, caps and a preservative specified on the drawing rather than assumed.
Orientation. If the part must travel one way up, say so and mark it on the part.
What to agree in the order
- The Incoterm, written out in full, and who insures the load
- Who arranges and pays for permits and escorts
- What the crating includes and whether it is returnable
- The preservation specification and how long it is meant to last
- Who provides the crane at the destination and to what capacity
- How the part is inspected on arrival, and what happens if transit damage is found
- The declared weight and dimensions, which the haulier will rely on
A short checklist for the RFQ
Delivery to: city, country or port. Access at destination: crane capacity, door or opening dimensions. Incoterm required: state it. Crating: required or not, returnable or not. Preservation: state the expected transit time and conditions.
Five lines, and every quote that comes back is comparable on freight as well as on machining.
What to do next
Get the destination crane capacity and the access dimensions before you send the RFQ. They are the two facts most often missing, and they are the two that cause the most expensive surprises on the day the truck arrives.

Frequently asked questions
At what size does freight stop being routine?
Roughly once the load passes the legal envelope for standard road transport in the country it is crossing, which for most of Europe and North America means somewhere around 2.5 m wide, 4 m high including the trailer, or about 24 t. Past that you are into permits and planned routes.
Who should arrange the transport, me or the shop?
Whoever has done it for a part this size before. Many heavy shops have regular hauliers and it is easier to let them book it. Just make sure the Incoterm says clearly who is responsible and who insures it.
Why do lifting points belong on the machining drawing?
Because they usually have to be machined or welded on, and adding them after the part is finished means handling a finished part to modify it. Design them in and they cost almost nothing.
