Cargo-worthy certifies four things: solid steel walls, a square frame, a floor that carries a load, and doors that close and seal. It says nothing about paint. Surface rust, faded coats and cosmetic dents are normal and still pass. What fails the grade are holes, soft floor spots and patched-over rot, the problems that actually let weather in.
Cargo-worthy is a structural claim, not a beauty claim. When a box is graded cargo-worthy, it means the walls are solid steel with no holes punched through, the frame is still square instead of racked out of true, the floor holds weight without flexing, and the doors close all the way and seal against the frame. Those four things are what let a certified box legally carry freight across an ocean, and they are the same four things that matter when the box is sitting on your gravel instead of a ship's deck.
Every container we sell in this grade starts from the same steel as a brand new one: 14-gauge Cor-Ten weathering steel built to shrug off decades outdoors. Cargo-worthy does not weaken that recipe. It only tells you the box in front of you has held onto the strength it was built with.
A cargo-worthy stamp has nothing to say about how a box looks. Years of ocean and yard service leave marks: surface rust wherever a scratch opened bare metal, a chalky or faded topcoat, dents from a forklift mast or stacking gear, scuffs on the corner posts. None of that fails the grade, because none of it touches the frame, the floor or the seal.
That is the trade you are actually making with a used box. You give up the factory finish and pick up years of proven service for less money. If the finish matters more than the price, that is a different grade entirely, covered on our one-trip page.
Wind and watertight sits just below cargo-worthy on the ladder. A WWT box keeps weather out and stays dry, but it has not been certified sound enough to ship freight again. Every cargo-worthy container is also wind and watertight; not every WWT container clears the higher bar.
As-is sits below both. An as-is unit is sold with a known problem, a hole, a rotted floor, a roof gone through to rust, and it belongs in a scrap pile or a welding project, not on your property for storage. We do not put that grade on a delivery truck.
Here is the part that trips buyers up: nobody polices the word cargo-worthy in an online listing. A dealer selling boxes sight unseen can type the label onto a stock photo from three years ago and never have to answer for what actually arrives. Most sellers are honest, but the words alone cannot prove it.
That is why we build our yard around letting you check the claim instead of taking our word for it. Walk the lot in Woodlawn or the sales lot in Wytheville, look at the actual box, and use our used container inspection checklist to confirm the frame, floor and doors match the grade before anything changes hands.
We will point you to the right grade and give you a real number the same day.
Same-day reply. We'll send a real number, a real delivery window, and any photos we need to confirm fit.
You'll hear back from us today (or first thing tomorrow if it's late). For anything urgent, call (276) 237-6144.
