Normally the payload for 20ft is nearly 25 TON, and 28 TON for 40ft. But per different shipping line and shipping route, there will have weight limit by carrier. Especially 20ft container.

Based on our operation experience, shipping line prefer cargo under 15-20t TON for 20ft. When overweight, special application is required and additional surcharge  will be incurred.

And for 40ft and 40HQ, normally only require less than the payload which painted on the container door.
