The Ultimate Guide on How to Pack for International Shipping.

When shipping internationally, your items face a long and complex journey. Unlike a domestic delivery, your package will be handled by multiple carriers, cross oceans, and undergo rigorous customs inspections. A poorly packed box is the #1 cause of damage, customs delays, and costly surprises.

Simply “using a good box” isn’t enough.

As an IATA-certified logistics partner, we’ve seen why shipments fail—and how to ensure they succeed. This is our expert guide on how to pack for international shipping, whether you’re sending a small package by air or a full household by sea.

Why Proper Export Packing Isn’t Just a Suggestion

Proper packing is about three things: Safety, Compliance, and Cost.

  • Safety: Your shipment will be stacked, moved by forklifts, and subject to turbulence or ocean movement. Our professional export packing services are designed to protect your goods from breakage and moisture.

  • Compliance: A poorly labeled or incorrectly packed item (e.g., undeclared batteries) can be flagged by customs in Lagos. This can lead to your entire shipment being detained, inspected, and fined.

  • Cost: Airlines and shipping lines charge by volumetric weight (the space your box takes up), not just its actual weight. An oversized, half-empty box will cost you significantly more. Efficient packing saves you money.

The Right Tools: Packing Materials for International Shipping

Using the right materials is the most important first step. Do not reuse old or damaged boxes for international transit.

  1. The Box: Use a new, double-walled or triple-walled corrugated cardboard box. A single-walled box (like a shoebox) will be crushed.

  2. The Cushioning:

    • Bubble Wrap: Essential for wrapping individual fragile items.

    • Packing Peanuts / Air Pillows: Use these to fill all empty space in the box to prevent items from shifting.

    • Foam Inserts: Best for high-value electronics or delicate industrial parts.

  3. The Tape: Use industrial-grade plastic packing tape (at least 2 inches wide). Do not use duct tape, masking tape, or standard office tape, as they will not hold.

How to Pack Your Box: A Step-by-Step Guide

  1. Wrap Individual Items: Wrap all fragile items in bubble wrap and secure with tape.

  2. Cushion the Bottom: Create a 2-3 inch layer of packing peanuts or crushed paper at the bottom of the box.

  3. Pack: Center and Fill:

    • Place the heaviest items at the bottom.

    • Place your most fragile items in the center of the box, surrounded by other items.

    • Fill all empty spaces and voids with packing peanuts or air pillows. The box should be firm and nothing should move when you shake it.

  4. Seal with the “H-Tape” Method:

    • Tape all the seams on the top and bottom of the box.

    • Then, apply tape across the middle seam and along the two side seams, forming a capital “H”. This provides the best structural support.

  5. Label Clearly: Remove all old labels. Apply your new shipping label flat on the top of the box. Include a duplicate label inside the box in case the outside one is damaged.

The Professional Difference: Air vs. Sea Freight Packing

How you pack should change based on the service you’re using.

  • Packing for Air Freight: The main concerns are weight and durability. Use strong, lightweight materials (like double-walled cardboard) to keep volumetric weight down.

  • Packing for Sea Freight: This journey is longer and harsher. Your items will be exposed to humidity, moisture, and immense stacking pressure in a container. For furniture or large items, plastic wrap and moisture-absorbing desiccant packs are highly recommended.
