"Why Was I Charged for 6.5kg When My Package Only Weighs 3.6kg?" — The Volumetric Weight Answer

This is the question we get more than almost any other, and it usually arrives sounding a little suspicious: "why am I being charged for 6.5kg when my package clearly says 3.6kg on the label?" It's a completely fair question. Here's the honest, full answer — using a real case, shipping a recovered item from Hong Kong to Japan.

The moment of confusion

The traveller had already paid, already received the shipment, and then looked closely at the DHL label:

"I noticed that the DHL shipping label states a shipment weight of 3.6 kg, while I was charged based on 6.5 kg. Could you please explain how the 6.5 kg chargeable weight was calculated?"

That's not a customer being difficult. That's a customer doing exactly the right thing — checking the math instead of just trusting it. The answer deserves to be given clearly, not defensively.

The two numbers that both exist, and why couriers charge the bigger one

Every international shipment has two weights: the actual weight (what it would read on a bathroom scale) and the volumetric weight (a calculated figure based on the size of the box, regardless of how light the contents are). The formula couriers worldwide use is:

Length × Width × Height (in cm) ÷ 5000 = Volumetric Weight (kg)

In this case, the box measured 48 × 36.9 × 18.3 cm. Run that through the formula and you land almost exactly at 6.5kg — even though the actual contents weighed only 3.6kg on a scale.

Why does this exist at all? Because a courier plane or truck runs out of physical space long before it runs out of weight capacity. A large, light box takes up the same volume as a heavy one, so couriers charge for whichever number is bigger — actual or volumetric — to reflect the space it actually occupies. This isn't a ParcelGo markup or a DHL quirk specifically; it's standard practice across FedEx, DHL, UPS, and every major international courier.

What this means practically, if you're shipping a recovered item

Packing matters more than most people expect. A recovered laptop bag padded generously for protection can easily push a shipment's volumetric weight well past its actual weight — and that difference is what you're billed on. It's worth asking, before a recovery ships, what the box dimensions are and doing the quick math yourself. We'll always share it upfront, because a surprised customer after delivery is a worse outcome for everyone than a slightly bigger number explained clearly before payment.

The other line item people ask about: D&T charges

The same conversation touched on "D&T" — duties and taxes that a destination country's customs might apply. For genuinely lost-and-recovered personal items (as opposed to newly purchased goods), these are typically waived once the right documentation — passport, travel proof, ownership declaration — is shown to customs. It's the same principle covered in our post on EU customs duty on recovered luggage — worth a read if you're shipping internationally.

Our end of the deal

When this traveller asked for a breakdown, we didn't just repeat "you were charged correctly." We went to our accounts team, got the exact line-item calculation, and shared it — because a vague reassurance isn't an answer, and a customer who does the math deserves to see ours too.

If a shipping quote looks higher than you expected

Ask for the box dimensions and run the L×W×H÷5000 formula yourself. If the volumetric figure is what you're being charged, that's standard industry practice, not padding. If the numbers don't add up even after that, ask for the line-item breakdown — any courier worth using will give it to you without an argument.
