Why Packaging Matters for International Shipments
International packages travel farther, change hands more often, and face more handling stress than domestic parcels. A poorly packaged shipment risks arriving damaged, being delayed at customs due to inadequate labelling, or incurring additional costs. Getting packaging right is one of the simplest ways to ensure a smooth delivery experience.
1. Choose the Right Box Size
Use a box that fits your items snugly without excessive empty space. Oversized boxes increase dimensional weight (which carriers use to calculate shipping costs) and allow contents to shift in transit. Undersized boxes put pressure on the contents and are more likely to burst or crush. A general rule: leave about 5–7 cm of space on all sides for cushioning material.
2. Use Adequate Cushioning Material
International shipments experience rough handling at multiple points — loading bays, aircraft holds, conveyor belts, and customs inspection tables. Protect your items with:
- Bubble wrap – ideal for fragile items like glassware or electronics
- Foam inserts or foam peanuts – fill empty space and absorb shock
- Air pillows – lightweight and effective for filling voids
- Crumpled kraft paper – an eco-friendly option for lighter items
Shake the sealed box — if you can hear or feel movement inside, add more cushioning.
3. Seal the Box Properly
Use strong packing tape (not masking tape or scotch tape) to seal all seams — top, bottom, and all four edges. Apply at least two layers of tape along the main seam. Reinforce the corners, which are the most vulnerable points during transit.
4. Label Clearly and Legibly
Customs and carriers rely on your label to process and deliver your package. Ensure your label includes:
- Full sender name and address (including country)
- Full recipient name, address, and phone number
- Accurate description of contents
- Declared value in the destination country's currency or a universally accepted currency
Print labels rather than handwriting them to avoid misreads. Apply the label to the largest flat surface of the box and cover it with a strip of clear tape to protect it from moisture.
5. Include a Duplicate Label Inside the Box
If the outer label gets damaged or detached in transit, a duplicate label inside the package allows the carrier to still identify and deliver it. Simply place a copy of the shipping label inside before sealing the box.
6. Complete the Customs Declaration Accurately
For most international shipments, you're required to attach a customs declaration form (CN22 or CN23 for postal services, or a commercial invoice for courier shipments). This form should accurately state:
- A clear description of each item (avoid vague terms like "gift" or "stuff")
- Quantity and weight of each item
- Declared value per item
- Whether the shipment is a gift, commercial sample, returned goods, or sale item
Never undervalue or misdeclare your contents. This can lead to seizure, fines, or a permanent flag on your shipping account.
7. Consider Environmental Conditions
Your package may travel through extreme temperatures, humidity, or altitude changes. If you're shipping items sensitive to temperature or moisture (such as food, cosmetics, or certain electronics), use insulated packaging or moisture-barrier bags. Mark the package clearly with handling instructions such as "Keep Dry" or "Temperature Sensitive."
