Common International Shipping Mistakes: 7 Easy Fixes

Most common international shipping mistakes are not dramatic. They are small, quiet decisions made in the ten minutes before a parcel leaves the house, and they show up later as a surcharge, a customs hold or a damaged box.

This guide lists the seven that cost people the most money, explains why each one happens and gives the fix. CourierAPP ships door to door to 220+ destinations worldwide through DHL and FedEx, with the final VAT-inclusive price shown before you pay.

Mistake 1: guessing the weight

This is the most frequent of all common international shipping mistakes, and the most avoidable. People estimate, book on the estimate, and are surprised when the invoice changes.

Carriers reweigh every shipment at the first hub. If your figure was low, the difference is adjusted afterwards. Nothing is being hidden from you, but nothing is being forgiven either.

The fix. Weigh the box on any bathroom scale: stand on it holding the parcel, then without it, and subtract. If you have no scale at all, the app can estimate weight from a description of the contents. You confirm the number before booking.

Mistake 2: ignoring volumetric weight

A large, light box is priced on the space it occupies, not on what the scale says. Duvets, lampshades and packing peanuts all cost far more than their weight suggests.

Carriers compare actual weight with volumetric weight and charge whichever is higher. That is standard across the industry, not a quirk of one network.

The fix. Use the smallest box that safely fits the contents. Cut down an oversized carton rather than filling it with air. Measure all three dimensions, or photograph the box beside a plain A4 sheet and let the AI estimate them.

Mistake 3: writing a vague content description

Gifts, personal items and sundries are not descriptions. A customs officer cannot classify them, so the shipment waits until somebody can.

Held parcels generate storage charges and re-delivery attempts, and both are billed. This is one of the common international shipping mistakes that costs time as well as money.

The fix. Write what is actually inside: used cotton clothing and shoes, one ceramic vase, three paperback books. Specific, honest, boring wording clears fastest.

Mistake 4: sending something restricted

People rarely do this deliberately. A power bank tucked into a bag of clothes, a bottle of olive oil as a present, a half-used aerosol in a toiletry case.

Any of these can stop the parcel, and in some cases the item is removed and destroyed without compensation.

• Loose lithium batteries and power banks.
• Aerosols, perfumes, alcohol and flammable liquids.
• Perishable food and anything needing refrigeration.
• Cash, jewellery and documents of monetary value.
• Weapons, replicas and pressurised containers.

The fix. Empty the box mentally item by item before sealing it, and check destination-specific rules for cosmetics, supplements and used clothing quantities.

Mistake 5: leaving old labels on the box

Reusing a carton is sensible and cheap. Leaving the previous barcode on it is not.

Automated scanners read whatever they see first. A leftover code from an earlier shipment can send your parcel to the wrong depot, and tracking will look normal while it does.

The fix. Remove or fully cover every old label, sticker and barcode. Attach the new label flat on the largest surface, never across a seam or a corner.

Mistake 6: choosing the wrong service level

Two versions of this exist and both are expensive. Paying for Express when nothing was urgent, and choosing Economy for something that had a real deadline.

Within Europe, Express is normally 1 to 3 working days and Economy 3 to 6. Both are collected from your door and both are tracked at every scan.

The fix. Decide the deadline before you look at prices. If nobody is waiting, Economy is the honest answer. A 5 kg parcel to Europe on Economy starts at €49.90 with VAT included.

Mistake 7: bad packaging for the journey

A box that survived one trip in a car will not necessarily survive a conveyor network, several handovers and a stack of heavier parcels on top of it.

Single-wall cardboard above about 5 kg, contents touching the outer walls, and tape on the top seam only are the three failures that appear again and again.

The fix. Use double-wall board for heavier loads, wrap fragile items individually, keep everything a few centimetres from the walls, and tape both top and bottom seams in an H pattern.

The customs mistakes nobody warns you about

Inside the European Union there is no customs step for personal shipments, so these problems simply do not arise on European routes.

Outside the EU, including the United Kingdom, the United States and Switzerland, a declaration is required and duty or import VAT may be payable by the recipient.

Two errors dominate. Understating declared value, which reduces any compensation you could claim and can be challenged anyway. And not telling the recipient that import charges may apply, which is how parcels end up refused at the door.

CourierAPP prepares the paperwork with the carrier, so your part is the description and the value. Both should be accurate.

The carrier perspective on international express standards is set out on the DHL Express website.

Delivery times and tracking: what is normal

Transit estimates are working days from collection and exclude the pickup day. Public holidays in either country extend them.

Tracking follows a predictable path: collected, origin hub, export, arrival, customs where applicable, local depot, out for delivery.

A quiet day or two mid-transit is normal and not a sign of a problem. A status that has not changed for several working days is worth a question.

No responsible courier guarantees a date for a shipment crossing a customs border. Treat any promise of one with suspicion.

Prices, so you can judge the trade-offs

All figures include VAT and reflect the live price list.

• Europe, 5 kg parcel, Economy: €49.90
• Europe, 10 kg parcel, Economy: €59.90
• Europe, 10 kg parcel, Express: €85.90
• Cyprus, 1 kg envelope, Express: €20.90
• United Kingdom, 10 kg parcel, Economy: €71.90

International shipping starts from €20.90. Inside Greece the DHL Express Domestic service starts at €13.90 for an envelope or parcel up to one kilo, positioned for next-working-day speed rather than lowest price.

How to book correctly in about 30 seconds

Avoiding common international shipping mistakes is mostly about the order you do things in. Here is the sequence that works.

Destination first. Country and city. No account is required to see a price, so you can compare before committing.

Addresses second. Type them, or photograph an existing label or invoice and let the AI address scanner read them. You confirm the result.

Weight and dimensions third. Measure if you can. If not, one photo with a plain A4 sheet beside the box gives the AI a reference to estimate from.

Service fourth. Economy and Express appear side by side with the final VAT-inclusive amount. This is where the deadline decision is made.

Collection last. Pick a day, pay online, receive the label by email and hand the parcel over at your door.

Mistakes that only appear on the recipient side

Half of failed deliveries have nothing to do with the sender packing badly. They happen at the far end.

An unmonitored phone number is the biggest one. Drivers call before or during delivery, and a number nobody answers becomes a failed attempt.

An incomplete address is the second. Building name, floor, apartment number and entrance code all matter in dense European cities.

A recipient who does not know a parcel is coming is the third. If import charges apply and nobody warned them, refusal is a common outcome.

The fix. Send the tracking number to the recipient as soon as you have it, along with the estimated window and a note about possible import charges on non-EU routes.

Multi-piece bookings: stop splitting shipments

Booking three separate shipments for three boxes going to the same address is a mistake that used to be unavoidable. It no longer is.

A single booking can carry up to 10 parcels. The form has an Add parcel button, the price is combined, and each piece gets its own tracking number.

One collection, one payment, one set of paperwork. For families relocating, students moving abroad and e-shops sending a batch, this is usually the single biggest saving available.

It also helps with weight bands: splitting a heavy load across several right-sized boxes often lands in better pricing than one oversized carton.

Documentation mistakes for non-EU destinations

Outside the European Union the paperwork is short but unforgiving. Small inconsistencies cause disproportionate delays.

Names must match identification. A nickname on the label and a legal name on the passport is enough to stall a collection at the destination.

Quantities must match the description. Three items declared and five in the box is treated as a discrepancy, not an oversight.

Currency must be stated. A number with no currency is ambiguous, and ambiguity is resolved slowly.

Some countries require a recipient tax or identification number. The app asks for it only where it is genuinely mandatory, so if you are asked, it is not optional.

Insurance, claims and evidence

Every shipment travels with standard carrier liability, calculated by weight rather than by the value of the contents. For ordinary goods that is usually adequate.

If the contents are worth more, declare the real value and add cover at booking. A claim can only ever reflect what was declared.

Photograph the contents laid out and the box sealed before it leaves. Keep receipts for anything valuable. Claims are decided on documentation.

If a parcel arrives damaged, note it at delivery and photograph the packaging before unpacking. Reporting later, with the box already flattened, weakens the claim considerably.

A pre-shipping checklist

• Box is the smallest that safely fits the contents.
• Weight and all three dimensions measured, not guessed.
• Deadline decided before the service was chosen.
• Content description specific and honest.
• Nothing restricted inside.
• Old labels removed, seams taped top and bottom.
• Recipient phone, email and full address confirmed.
• Everything going to one address in a single multi-piece booking.

Eight lines, two minutes, and most of the common international shipping mistakes in this guide simply stop happening.

Let the AI handle the measuring

If measuring is the step you always skip, hand it over. The app estimates dimensions from a single photo using a plain A4 sheet as a ruler, with a green frame guide to help you line up the shot.

It is an assistant rather than a replacement. You confirm the numbers, and the carrier reweighs on collection so only the difference is ever adjusted. Photos are used solely to calculate the shipment.

See how it works in our guide to measuring a parcel from a photo, and compare related reading in parcel shipping mistakes and extra charges and sending a parcel abroad without mistakes.

Travellers: the forgotten-item mistake

Leaving something behind at a hotel, villa or short-term rental is its own category of problem, and it has a straightforward answer.

The traveller arranges and pays for the return online through the Lost and Found service, seeing the final VAT-inclusive price before confirming. The property receives a prepaid label by email, hands the item to the courier and pays nothing.

Packaging materials that actually work

Good packaging is cheap and boring. Bad packaging is expensive and interesting, which is why it appears in every damage story.

Double-wall cardboard is the baseline for anything above roughly 5 kg. Single-wall is fine for clothes and light goods, and inadequate for books, tools or ceramics.

Bubble wrap protects surfaces; crumpled paper fills voids. You usually need both, and neither works if the contents can still shift when you shake the box gently.

Wide packing tape, not household sticky tape. Reinforced tape on heavy loads. Tape the bottom seams before you fill the box, not after.

Skip string and rope entirely. They catch in sorting machinery and are refused by most networks.

For suitcases, wrap the zip line in stretch film or use a fabric cover so nothing snags in transit.

Seasonal timing mistakes

Volume is not constant through the year, and transit estimates stretch when networks are busy.

The weeks before Christmas are the obvious peak, but the September and January student waves are just as congested on European routes.

Public holidays are the quiet trap. A shipment booked on a Thursday before a long weekend in the destination country loses days that were never in the estimate.

The fix. Add a working week of margin during peak periods, and check the destination holiday calendar rather than only the Greek one.

When a parcel goes wrong: the right order of steps

Panic produces phone calls. Evidence produces resolutions.

Start with the tracking number and the last scan. That single data point tells you whether the parcel is in transit, held at customs or sitting at a local depot.

If it is held at customs, the usual cause is documentation, and the usual fix is a clearer content description or a missing recipient identification number.

If it is at a local depot after a failed attempt, contact the recipient before contacting the courier. Most cases are resolved by rescheduling.

Only escalate when the tracking has genuinely not moved for several working days, and bring the number, the booking reference and the declared contents with you.

Business shippers: the mistakes that scale

A mistake that costs a private sender a few euros costs a repeat shipper a margin. The same errors simply repeat.

Inconsistent box sizes are the most damaging. Standardising on two or three cartons that match your typical order makes weight bands predictable and surprises rare.

Ad hoc collections are the second. Batching pickups into one daily slot cuts both cost and the time somebody spends waiting for a driver.

Copy-pasted vague descriptions are the third. If the wording is wrong once, it is wrong on every shipment of that product until somebody fixes it.

Track your own failure rate. Returns and failed deliveries erode international margin far more quietly than headline rates do.

Where you can ship: 220+ destinations worldwide

Route availability is rarely the issue. The network reaches 220+ destinations worldwide through DHL and FedEx, including Europe, the United Kingdom, Cyprus, the United States, Canada, Australia and the Gulf.

What changes between them is paperwork and transit estimate, not the door-to-door principle. European Union routes have no customs step, which makes them the most predictable and the most forgiving of small errors.

Long-haul routes are less forgiving, because a documentation problem compounds with a longer transit. That is where the checklist earns its keep.

Conclusion

None of these common international shipping mistakes require expertise to avoid. They require two minutes of attention at the point where most people are already in a hurry.

Measure properly, describe honestly, pack for a conveyor belt rather than a car boot, and choose the service that matches the deadline. The rest of the process takes care of itself.
