Car parts break the usual parcel assumptions in three ways at once: they are dense, they are awkwardly shaped, and many of them carry residues that make them restricted. A pair of alloy wheels, a bumper and a gearbox are three completely different shipping problems despite all being car parts. The published weight ladder is the useful anchor: Parcelforce prices from 11.95 pounds up to 5kg, 14.20 to 10kg, 17.95 to 20kg and 21.40 to 30kg, and most single parts land in the upper two bands.
Shipping car parts: the weight bands most of them land in
A single alloy wheel typically sits in the 10 to 20kg range, which puts it in Parcelforce's published 17.95 pounds band, and a pair pushes into the 21.40 pounds band up to 30kg. Bands price at their ceiling, so a 12kg wheel and a 19kg wheel cost the same on that ladder. Above 30kg the published ladder ends and the consignment is quoted individually, which is where a set of four wheels, a gearbox or an engine belongs. Knowing which side of 30kg you are on is the first thing to establish.
Shape is the second problem
Panels, bumpers, exhausts and bonnets are long or bulky rather than heavy, and they are priced on volumetric weight, meaning the space they occupy rather than the scales. Every service also caps maximum length and girth, and a bumper commonly exceeds them, which pushes it out of the parcel network and into a freight or dedicated courier product. Measure the longest dimension first: if it is over about 1.5 metres, expect to be quoted outside the standard parcel tiers whatever the item weighs.
What makes a part restricted
This is where car parts trip people most often. Anything that has held fuel or oil is treated as a dangerous goods risk even when drained, which covers fuel tanks, fuel pumps, used engines and gearboxes. Airbags and seatbelt pretensioners contain pyrotechnic charges and are classed as explosives, so they cannot travel on standard services at all. Batteries, shock absorbers containing pressurised gas, and paint or aerosols each carry their own rules. Declare accurately: an undeclared dangerous item is the sender's liability, not the carrier's.
Packing wheels and panels so they survive
Alloy wheels need the face protected and the whole wheel boxed rather than shrink wrapped, because an exposed rim gets kerbed in transit and a scuffed face destroys the value of the part. Use a wheel specific box or a double walled carton with corner protection and the centre filled so the wheel cannot rotate. Panels need edge protection and a rigid backing, since a crease is unrepairable. Photograph everything before it leaves, because a damage claim on a high value part without pre despatch photographs is very hard to win.
Questions people ask about car parts courier
What does an alloy wheel courier charge?
A single wheel usually falls in Parcelforce's published up to 20kg band at 17.95 pounds, and a pair in the up to 30kg band at 21.40 pounds. Above 30kg the published ladder ends and the consignment is quoted individually.
Can I send a fuel tank or a used engine?
Generally not on standard services. Anything that has held fuel or oil is treated as a dangerous goods risk even when drained, and undeclared dangerous items are the sender's liability.
Why is my bumper quoted outside the parcel bands?
Length and girth limits. Panels and bumpers are priced on volumetric weight and commonly exceed a service's maximum dimensions, which pushes them into a freight or dedicated courier product.
Are airbags shippable?
Not on standard services. Airbags and seatbelt pretensioners contain pyrotechnic charges and are classified as explosives.
Is an alloy wheel delivery service different from a parcel courier?
Not usually a different company, only a different band. A single wheel falls in one published weight band and a pair in the next one up, on the same networks that carry an ordinary parcel. What changes is the packing: the face has to be protected and the whole wheel boxed rather than shrink wrapped, because an exposed rim gets kerbed in transit.
