Packing is where the invisible tax lives. Oopbuy charges on chargeable weight — the higher of actual weight or volumetric weight — and beginners routinely overpay because they don’t request tighter packing. Get this right and you’ll typically shave 10–30% off your oopbuy shipping invoice, sometimes more. Pair this with oopbuy shipping explained for the line-level view.
Volumetric weight in one paragraph
For most air lines, volumetric weight = (L × W × H in cm) ÷ 6000. A big box of light things (puffer jackets, boxed sneakers) will bill volumetric almost every time. Attack the volume, not the mass.
The packing request checklist
- Ask the warehouse to remove shoe boxes unless you actually need them.
- Request vacuum bags for jackets, hoodies and coats.
- Group by material — soft items compress, hard items go in the corners.
- Keep fragile items in original packaging only when damage risk is real (electronics, perfume).
- Fold instead of roll for tighter dimensions.
- Choose the smallest carton option in oopbuy’s parcel builder.

The volumetric-heavy hall of shame
- Puffer jackets and down coats
- Boxed sneakers
- Winter boots
- Any large, low-density item
Customs-friendly packing
Customs cares about declared value, item mix, and quantity. Red flags to avoid:
- Mixing perfume + electronics in the same air parcel.
- 10+ identical units (looks commercial).
- Under-declaring value below realistic thresholds — a slower parcel is better than a seized one.
