Remember that the stuff that goes back to China, Japan, Korea, etc is often recycled material, especially metal scrap or paper/cardboard, which are very heavy if you load them into a 20-foot container. 40-foot ISO containers and domestic containers carry lighter things like microwave ovens, televisions, model trains, etc. The 20-foot containers I see in the Los Angeles area are almost always on 3-axle trailers.
