You sold a part, now you have to ship it. What now?
Congratulations, you sold a used car part! Maybe you offered it through the PoDi platform, maybe through an ad, but the point is the same: someone paid you and now expects that part to arrive in the same condition you described. And between your garage and the buyer's hands stands a courier service that carries, throws, stacks and drives that package in a truck full of other packages.
Poor packing is the most common reason for complaints in online used parts sales. A part that was in perfect condition can arrive broken, scratched or damaged if it is not properly protected. Then the problems start: the buyer demands a refund, you lose the money on postage and the part, and everyone is unhappy.
Packing is not just "put it in a box". Small sensors and large bumpers follow different rules. Here is what you actually need, how to wrap each type of part, and which courier service to pick for what.
Packing materials you should have
Before you start packing, get these materials. You can get most of them for free or cheap:
- Cardboard boxes - in various sizes, preferably double-walled cardboard for heavier parts
- Bubble wrap - the main protection for most parts
- Newspaper or filler paper - for filling empty space in the box
- Stretch film - for wrapping parts that must not get scratched
- Adhesive tape - wide, brown packing tape, not regular cellotape
- Styrofoam or foam padding - for fragile parts like headlights and glass
- Plastic bags - for small parts and screws
- Marker - for labelling "FRAGILE" and "THIS SIDE UP"
Where to get them? Bubble wrap and boxes can be bought at hardware stores or online. But before you spend money, ask local shops if they have cardboard boxes to throw away. Most of them will happily give them away.
Basic rules for packing car parts
Regardless of which part you ship, these rules always apply:
Rule 1: the part must not move inside the box
This is the most important rule. When you close the box and shake it, the part inside must not move. Any movement means the part is hitting the walls of the box, and that means damage. Fill every empty space with paper, bubble wrap or styrofoam.
Rule 2: protect sensitive surfaces
Connectors, threads, sealing surfaces and any surface that must remain undamaged need extra protection. Wrap them in bubble wrap or fit a plastic cap if you have one.
Rule 3: box inside a box for fragile parts
For truly fragile parts (headlights, glass, electronic control units), use the box-in-a-box principle. Put the part in a smaller box with bubble wrap, then put that box in a larger one with extra padding around it. Double protection dramatically reduces the risk of damage.
Rule 4: drain liquids
People often forget this one. Parts like pumps, radiators, AC compressors and similar can contain liquid. Drain them as best you can and wrap them in a plastic bag in case something leaks. Courier services do not like wet packages and can refuse delivery.
Rule 5: document the condition before shipping
Photograph the part before packing and during packing. If a complaint comes up, you have proof of the condition the part was in when you sent it. This is especially key for more expensive parts.
How to pack specific parts
Small parts (sensors, relays, spark plugs, small electric motors)
Small parts are usually the easiest to pack, but do not underestimate them. A lambda sensor with a damaged thread is useless.
- Wrap each part separately in bubble wrap
- Put it in a plastic bag
- Place it in a small box with padding around it
- If you are shipping several small parts in one package, each must be separately protected so they do not knock into each other
Electronic components (ECU, control units, instrument cluster)
Electronics are sensitive to impacts and static electricity. Wrap them in an antistatic bag (or at least a regular plastic one), then in bubble wrap, then in a box. Never ship electronics in an envelope or without a box.
Headlights and tail lights
Headlights are fragile and pricey. Use the box-in-a-box principle. The headlight lens scratches easily, so wrap it in a soft material (an old towel works great). Fill the space around the headlight in the box so densely that the headlight cannot move at all.
Bumpers and large plastic parts
Bumpers are tricky because of their size. Most courier services have limits on package dimensions. Here are your options:
- If a bumper fits in a large box, wrap it in stretch film and place it in the box with padding
- If it does not fit in a box, wrap it in bubble wrap, then in stretch film, and clearly label "FRAGILE"
- For large parts, consider a pallet service instead of regular post
- Personal delivery is often the best option for large parts, especially if the buyer and seller are in the same city or region
Metal parts (alternator, starter, pumps, brake callipers)
Metal parts are heavy and tough, but they can have sensitive connections. Wrap connectors in bubble wrap, and the whole part in newspaper or paper so it does not scratch the box (and other packages). Use a strong, double-walled box because the weight can puncture thin cardboard.
Glass parts (windscreen, side, rear)
Car glass is one of the hardest parts to ship. It is heavy, fragile and large. If you can at all, arrange personal pickup for glass. If you have to ship:
- Use specialised boxes for glass (they have a slot that holds the glass upright)
- Place cardboard or styrofoam on both sides of the glass
- Label the package clearly: "GLASS - FRAGILE - DO NOT DROP"
- Consider extra insurance on the shipment
Courier services: which to choose?
Different courier services have different rules for car parts. Here is an overview:
GLS
Maximum package weight: 31.5 kg. Dimensions: longest side up to 200 cm, girth up to 300 cm. Good coverage in the region and acceptable prices for standard packages. For medium-sized car parts, GLS is a solid option.
DPD
Maximum weight: 31.5 kg. Fast delivery, good shipment tracking. The price is a bit higher than GLS, but the service is reliable.
National postal services
For small and light parts, national post is the cheapest option. But for heavier packages and non-standard sizes, commercial couriers are a better choice. Typical limits: 30 kg and dimensions up to 150 cm on the longest side.
Pallet services
For engines, gearboxes and other large, heavy parts, use a pallet service. Place the part on a Europallet, secure it with straps and wrap it in stretch film. Services like DB Schenker or similar logistics providers offer pallet delivery. The price is higher (50 to 150 EUR depending on weight and route), but for an engine worth 1,000 EUR that is an acceptable cost.
Shipping cost: how to reduce it?
Postage can be a significant cost, especially for heavier parts. Here are tips for saving:
- Use the smallest possible box - courier services charge by dimensions or weight (whichever is greater), so do not put a small part in a large box
- Negotiate the price - if you ship packages regularly, contact the courier service for contract rates
- Compare prices - every service has a calculator on its website, check them all before shipping
- Offer personal pickup - for local buyers, this eliminates postage cost entirely
- Include postage in the part price - buyers love seeing "free delivery", even if the part price is slightly higher
Insuring the shipment
For parts worth more than 100 EUR, consider insuring the shipment. Most courier services offer basic insurance up to a certain amount (usually 50 to 100 EUR), and you can pay extra for higher amounts.
Document the part's condition and packing with photos. In case of damage, this is your proof for a claim with the courier service. Without proof, you will have a hard time getting compensation.
Common mistakes when shipping car parts
From experience, here are the most common mistakes sellers make:
- Too little protection - "it's solid, it'll hold up" is a phrase that usually ends in a complaint
- Reusing old boxes without checking - old boxes are fine, but check that the cardboard has not softened or been damaged
- Forgetting about liquids - if oil leaks in the courier's van, you will have problems
- Wrong details on the package - check the address, name and phone number of the recipient
- Shipping without coordinating with the buyer - tell the buyer when you are shipping and give them a tracking number
How packing affects your reputation
If you sell used parts regularly, the way you pack and ship parts directly affects your reputation. A buyer who receives a well-packed part in the described condition will come back to you and recommend you to others. A buyer who receives a damaged part in a thin bag will not.
On platforms like PoDi, a good reputation means more buyers and faster sales. Invest those extra 10 minutes in packing because it pays off in the long run.
Practical tip for the end
Set up a "packing station" in your garage. Keep a stock of boxes, bubble wrap, tape and newspaper in one place. When you sell a part, packing takes you 10 to 15 minutes instead of an hour because you do not have to hunt for materials. And while you wait for a buyer, browse the PoDi platform for new requests and offers. Maybe you have exactly the part someone is looking for.
Remember: a well-packed part is a part that arrives in the same condition it was sent. And that means a happy buyer, zero complaints, and money that stays in your pocket. It is worth a little effort.
