How to ship auto parts: tires, bumpers, engines and batteries
Measure the packed box, then compare.
To ship auto parts as UPS parcels, box each part, keep it at 150 lb or less and inside UPS size limits. Unboxed tires, long parts like bumpers and hoods, and heavy engines draw surcharges, while batteries, airbags and parts that held fuel can be regulated hazardous materials, so check UPS's hazmat rules first.

A quote needs the real weight and the box's length, width and height, and the box size goes to the carrier with every live quote, so each price reflects dimensional weight.

Which auto parts can ship as parcels?
Most boxed auto parts can ship as parcels, as long as each package weighs 150 lb or less, is no longer than 108 inches and measures no more than 165 inches in length plus girth, which are UPS's limits. Inside those limits the question is price, not permission: bare tires, long panels, heavy castings and crated parts each cross a UPS line that adds a surcharge.
Batteries, airbags and parts that held fuel are the exception, because they can be regulated hazardous materials. The dated facts below are the lines that set the price, and the table after them sorts common parts by the line each tends to meet.
UPS and USPS facts, checked
- UPS limits per package: 150 lb, 108 inches long and 165 inches in length plus girth (girth is twice the width plus twice the height). UPS does not accept a package past any of them and adds Over Maximum Limits charges if one is found in its network; a package over 150 lb is freight to UPS.

- Billable weight is the greater of actual weight, rounded up to the next pound, and dimensional weight. On UPS daily rates, dimensional weight is length x width x height in inches divided by 139, with each side rounded up to the next whole inch and the result rounded up to the next pound. Source: UPS 2026 Rate and Service Guide, updated September 7, 2026, p. 19.
- Additional Handling, per package: actual weight over 50 lb, $46.50 in zone 2 to $58.75 in zones 7 and up; longest side over 48 inches, second-longest side over 30 inches, length plus girth over 105 inches or more than 10,368 cubic inches, $30.00 to $40.50 by zone, billed at no less than 40 lb; packaging, such as anything not fully encased in corrugated cardboard, which UPS says includes tires, $26.75 to $33.75 by zone. UPS charges one Additional Handling per package. Sources: UPS 2026 Rate and Service Guide, updated September 7, 2026, p. 179; UPS Tariff and Terms of Service, effective April 17, 2026, item 40.9.
- Large Package Surcharge: longer than 96 inches, length plus girth over 130 inches, more than 17,280 cubic inches or over 110 lb. It is billed at no less than 90 lb, replaces Additional Handling, and costs $219.50 in zone 2 to $286.00 in zones 7 and up for a business address, more for a home.

The dollar amounts are UPS's published 2026 charges per package, before fuel. Published carrier rates and fees are a benchmark, not what a GoatLabels label costs: a GoatLabels label is bought at the live carrier rate quoted for your packed, measured box, shown as one all-in number per carrier. Every amount by zone is in the guide to UPS Additional Handling and Large Package surcharges.
| Part | Typical packing | Likely UPS treatment | Parcel or freight |
|---|---|---|---|
| Sensors, filters, gaskets, small trim | A small corrugated box with padding on every side. | Billed on the greater of actual and dimensional weight, with no surcharge while the box stays under every line. | Parcel |
| Brake rotors, drums, calipers, hubs | A small, strong box with dense cushioning, since the weight is concentrated. | Dense, so actual weight tends to set the price; a box over 50 lb adds Additional Handling for weight. | Parcel |
| Tires and wheels | One per package: boxed in corrugated cardboard, or bare with the label on a tape band. | Bare adds Additional Handling for packaging, because UPS names tires; boxed is measured by its box. | Parcel |
| Bumpers, hoods, doors, body panels | A long, flat corrugated box, with paint and edges protected inside it. | Additional Handling past 48 inches long or 30 inches on the second side; a Large Package past 96 inches long or 130 inches in length plus girth. | Parcel within UPS's 108 inch length and 165 inch size limits; freight beyond. |
| Exhaust pipes, driveshafts, long trim | A long, narrow corrugated box; a mailing tube counts as a cylinder, which is its own trigger. | Additional Handling past 48 inches long, billed at no less than 40 lb; a Large Package past 96 inches. | Parcel within UPS's 108 inch length limit; freight beyond. |
| Engines, transmissions, axles | A box rated for the weight on UPS's box strength chart; a wooden crate is not corrugated, which is its own trigger. | Additional Handling over 50 lb, UPS's Heavy Package sticker over 70 lb, and a Large Package over 110 lb, billed at no less than 90 lb. | Parcel within UPS's 150 lb limit; freight beyond. Check UPS's hazmat guidance for used parts first. |
| Batteries, airbags, parts that held fuel | As UPS's hazardous materials guidance sets out for that item. | Can be regulated hazardous material; UPS's guidance decides whether a hazmat contract is needed. | Check before you pack; GoatLabels does not offer hazmat shipping. |

How do you ship tires and wheels?
Ship each tire or wheel as its own package, either boxed in corrugated cardboard or bare with the label on a band of tape, and expect UPS to add Additional Handling to any tire that is not fully boxed. The charge is per package, so four bare tires pay it four times, and FedEx names tires in its own handling list too.
Boxing removes the packaging charge but not the size math. UPS measures a bare tire at its extreme points, as if it sat in a rectangular box, and measures a boxed tire by its box, which is bigger, so the box adds dimensional weight while it saves the handling charge. A bare 27 x 27 x 9 inch car tire weighing 25 lb bills at 48 lb. Quote your own tire both ways on the same lane, then add UPS's packaging Additional Handling, and any demand surcharge on it, from the dated facts to the bare-tire quote before you choose. A quote built from weight and size alone cannot tell that the tire is bare.
To ship a tire bare, use UPS's labeling method and quote the tire as it will travel:
- Run a wide band of pressure-sensitive tape through the center and around the tire.
- Attach the shipping label to the tape band over the tread.
- Cover the label with clear tape.
- Weigh the tire, measure it at its extreme points, quote it with those numbers, and add UPS's packaging Additional Handling to that quote.
| Option | Label | UPS Additional Handling | Billable weight |
|---|---|---|---|
| Bare tire | On a wide tape band through the center and around the tire, over the tread, under clear tape. | Yes, for packaging: UPS names tires. | The tire measured at its extreme points, or its actual weight if higher; a 27 x 27 x 9 inch tire at 25 lb bills 48 lb. |
| Bare wheel or rim | Taped on a flat surface, with sharp edges blunted by corrugated pieces and no hanging tags. | Yes, for packaging: it is not fully encased in corrugated cardboard. | The wheel measured at its extreme points, or its actual weight if higher. |
| Tire or wheel in a corrugated box | On a flat face of the box, not on a seam, edge or sealing tape. | None for packaging; a size or weight line can still apply. | The box measured, or its actual weight if higher; the box is larger than the part, so it bills more dimensional weight. |

How do you ship bumpers, hoods and other long parts?
Ship a long part in the shortest, narrowest corrugated box that protects it, because size sets its price long before weight does. Past 48 inches long a box adds UPS Additional Handling, billed at no less than 40 lb; past 96 inches long or 130 inches in length plus girth it becomes a Large Package, billed at no less than 90 lb; past 108 inches long or 165 inches in length plus girth, UPS does not accept it.
A bumper shows how fast this adds up. A 72 x 20 x 16 inch bumper box weighing 30 lb measures 144 inches in length plus girth (72, plus twice 20, plus twice 16), so it is a Large Package, and UPS bills its dimensional weight of 166 lb plus the Large Package Surcharge. Trimming the box's width and height until length plus girth is 130 inches or less leaves it with Additional Handling instead. USPS will not take the 144 inch box at all, because its limit is 130 inches.
Hoods, doors and body panels add width, and a second-longest side over 30 inches adds Additional Handling even on a short box. Protect paint and edges inside the box rather than with wrap outside it, because an outer layer of shrink wrap or stretch wrap is an Additional Handling trigger too. A part past UPS's maximums goes by freight instead.
| Line | UPS treatment | Billed at no less than |
|---|---|---|
| Longest side over 48 in | Additional Handling | 40 lb |
| Second-longest side over 30 in | Additional Handling | 40 lb |
| Length plus girth over 105 in | Additional Handling | 40 lb |
| Longest side over 96 in | Large Package Surcharge, in place of Additional Handling | 90 lb |
| Length plus girth over 130 in | Large Package Surcharge, in place of Additional Handling | 90 lb |
| Longest side over 108 in | Not accepted; if found in the UPS network, Over Maximum Limits charges on top of the Large Package Surcharge | 90 lb (Large Package), if found in the network |
| Length plus girth over 165 in | Not accepted; if found in the UPS network, Over Maximum Limits charges on top of the Large Package Surcharge | 90 lb (Large Package), if found in the network |

How do you ship engines, transmissions and other heavy parts?
Ship a heavy part as a parcel only while the packed box weighs 150 lb or less, and plan for UPS's weight lines on the way there: over 50 lb it adds Additional Handling, over 70 lb it requires its Heavy Package sticker to the right of the address label, and over 110 lb the Large Package Surcharge applies, billed at no less than 90 lb. Past 150 lb, UPS treats the package as freight.
Pack for the load. For packages over 70 lb, UPS asks for a strong, new box, preferably with stitched or stapled seams, dense cushioning rather than packing peanuts or crumpled paper, which crush and shift under heavy loads, and three strips of heavy-duty tape across both the top and the bottom. A wooden crate counts as packaging that is not corrugated cardboard, its own Additional Handling trigger, though UPS charges only one Additional Handling per package.
Used engines and transmissions raise one more question. UPS lists engine parts among items that may contain fuel, fuel residue or batteries and so may be regulated, so read UPS's hazardous materials guidance before you pack a used one, and do not buy an ordinary label until you know the answer.

What about batteries, airbags and fuel parts?
Batteries, airbags and parts that held fuel can be regulated hazardous materials, so check UPS's hazardous materials guidance for the exact item before you pack it. The answer depends on the specific item, so this guide does not rule on any part.
UPS says several battery types are regulated, including spillable lead-acid batteries and many lithium batteries, and that these may only be shipped by contract hazmat shippers. Its guidance also sets out exceptions, such as batteries tested and proven non-spillable, and the markings they need. UPS requires a dangerous goods contract for hazardous shipments that need shipping papers.
GoatLabels does not offer hazmat shipping: if a part is regulated, arrange it with the carrier under its rules rather than on an ordinary label. Everything else on this page assumes a part UPS treats as an ordinary parcel.

Shipping auto parts, answered
- Do tires need to be boxed to ship with UPS?
- No. UPS accepts a bare tire with the label on a band of tape run through the center and around the tire, but it charges Additional Handling on any tire that is not fully encased in corrugated cardboard. A boxed tire avoids that packaging charge, though UPS then measures the box instead of the tire, so it bills more dimensional weight and can cross a size line of its own.
- Can a car bumper ship without the UPS Large Package Surcharge?
- Yes, if the box measures 130 inches or less in length plus girth, 96 inches or less on its longest side and 17,280 cubic inches or less, and weighs 110 lb or less; past any of those lines UPS charges the Large Package Surcharge. A 72 x 20 x 16 inch bumper box measures 144 inches in length plus girth, so UPS bills it at its 166 lb dimensional weight plus that surcharge. Narrowing the box until length plus girth is 130 inches or less leaves the 72 inch box with Additional Handling instead, a far smaller surcharge, and a lower dimensional weight.
- Does a used engine count as hazardous material for UPS?
- It can: UPS lists engine parts among items that may contain fuel, fuel residue or batteries and so may be regulated, so check UPS's hazardous materials guidance for that engine before you pack it. If it is not regulated, UPS accepts it as an ordinary parcel while the packed engine weighs 150 lb or less and fits UPS's size limits, with Additional Handling over 50 lb, replaced by the Large Package Surcharge over 110 lb; past 150 lb, UPS treats it as freight.
- How do I ship a set of four wheels for less?
- Quote one wheel boxed and one bare on the same lane, add the Additional Handling that UPS and FedEx charge on an unboxed wheel to their bare quotes, then compare carriers for all four. UPS adds Additional Handling to every wheel or tire that is not fully boxed in corrugated cardboard, and charges it per package, while a box adds dimensional weight to each one. USPS takes parcels up to 70 lb but bills large ones by dimensional weight and adds fees for long or bulky boxes, so quote USPS too.
- Are parts shipped to a repair shop charged as residential?
- Not if the shop is a business location rather than a home. UPS charges its Residential Surcharge for delivery to a home, including a business run from a home, so a mechanic working out of a home garage is a residential delivery and a shop at a commercial address is not. For a Large Package the gap is wider, because UPS's Large Package Surcharge is higher for residential delivery.
