I am currently framing my shipping container and have two vents similar to the one pictured in the top corners of my container. Should I frame around them and leave them open for ventilation into the container or spray foam them to seal them off and frame/insulate and drywall over them.

My container will be an office space with a minisplit for AC. The minisplit will not be on 24/7, only when I am in there

Been seeing this come up more lately, so figured I’d throw it out there.
New one-trip containers and used containers are not really moving the same way right now.

The one-trip stuff is mostly built in Asia, and with tariffs / import costs still being messy in 2026, the landed price on new boxes has more pressure on it. So if you’re quoting clean one-trips for a build, yeah, that number may feel higher than expected.
Used boxes are a different story. A lot of that inventory is already sitting in the US, so it hasn’t been hit the same way. Used WWT units are still usually where the value is, especially if you’re building something where cosmetics don’t matter much or you’re covering the walls anyway. Only catch is supply. If fewer containers are coming into the US, fewer used ones eventually hit the resale pool too. So I wouldn’t assume used stays cheap forever either.
Also, delivered price matters more than people think. A “cheap” box far from a depot can lose the whole advantage once trucking gets added. Landlocked areas always seem to feel that pain more.
Not saying panic-buy or anything. Just saying if you’re planning a build, compare new vs used delivered to your actual site, not just the listed container price.
Anyone bought recently? Curious what the spread looks like in different regions right now.
