Metal Bolts vs Plastic Clips: Why Your Crate Will Be Rejected
You bought an expensive 'airline approved' crate. You measured your pet correctly. You have all the documents. But for cargo, IATA requires the two halves of a plastic crate to be bolted together: plastic clips alone are not sufficient.

The Plastic Clip Problem
Many plastic pet crates come with PLASTIC CLIPS securing the top and bottom shell.
IATA Pet Container Requirements state that the top and bottom halves of plastic containers must be bolted together, and that plastic clips alone are not sufficient. Metal bolts are recommended in every hole.

What Airlines Actually Require
For cargo transport, IATA requires:
ACCEPTABLE:
NOT SUFFICIENT ON THEIR OWN:
Your airline may add its own requirements (for example cable ties). Check its official policy.

How to Fix Your Crate
You don't need to buy a new crate. Here's how to upgrade:
WHAT YOU'LL NEED:
STEP BY STEP: 1. Remove plastic clips 2. Line up top and bottom shells 3. Insert bolt through existing holes 4. Add washer and nut on inside 5. Tighten firmly (not overtight - don't crack plastic) 6. Add zip tie through same holes as backup 7. Repeat for all four corners
Check the airline's official policy for any additional fastening requirement.
Visual Inspection at Check-In
When the airline agent inspects your crate, they will:
1. Check ALL four corners for secure fastening 2. Pull on the shell to test if it separates 3. Verify metal hardware (they know plastic from metal) 4. Ensure clips aren't just hidden under tape
If they see plastic clips - or if the shells move when pulled - your crate fails.
Check Your Crate Before You Fly
