Question 1

What does "One-Trip" actually mean, and how is it different from a brand-new container?

Accepted Answer

One-Trip is the standard industry name for a container that has made exactly one cargo voyage — typically from the factory in China where most dry containers are manufactured to a discharge port in Europe, the Americas or Africa. It was loaded with paying cargo on that single voyage to offset the repositioning cost; if it had moved empty, it would have been labelled New. In every practical sense — paint, floor, door seals, structural condition, certified maritime lifespan — a One-Trip is effectively new: it has more than 24 years of remaining certified service ahead of it, the manufacturer's QC is intact, and the only difference from a truly brand-new unit is that single loaded leg, which leaves no visible trace on a well-handled box. The reason the One-Trip grade exists at all is logistical: manufacturers and traders move new containers from factory to demand markets, and selling them as One-Trip with that single voyage embedded in the sale is cheaper for both sides than positioning empties. For the buyer, One-Trip is the practical near-equivalent of New at a lower price — which is why it dominates the near-new market segment.

Question 2

How many voyages has a typical Cargo Worthy container made, and how old is it?

Accepted Answer

A typical Cargo Worthy container at the point of sale is roughly 8 to 12 years into its maritime life, having completed dozens to over a hundred international rotations depending on the trade lane. The exact number is rarely tracked at unit level — what matters for the CW grade is the current condition, not the count of past voyages — but the age range is consistent because that is when most containers move from active liner fleets, which prefer younger boxes for operational reasons, into the secondary market. A CW unit has typically been used by one or more shipping lines, then sold off as part of fleet rotation, inspected against the CSC standard, certified for further maritime service, and is offered with roughly 15 years of certified maritime life still ahead of it (see our guide on container lifespan). Practical implication: a CW is not old in any meaningful sense — it's mid-life, with significant remaining service life on water and effectively unlimited remaining life on land.

Question 3

How much cheaper is a Cargo Worthy than a One-Trip?

Accepted Answer

A CW unit typically sells for roughly half the price of an equivalent One-Trip in stable markets, sometimes less in well-supplied regions, sometimes closer to the One-Trip price in undersupplied or distant markets. For a 20DC, that often means starting around 800 USD for CW in well-supplied locations, compared to a 20DC One-Trip that sits closer to the New price band. For a 40HC, the gap is similar in proportion — a CW well below the 4,000 USD ceiling that a One-Trip 40HC can reach in undersupplied cities. The price gap is driven less by remaining lifespan (CW still has years of certified life ahead) and more by buyer perception and market positioning: One-Trip carries the near-new premium, CW is positioned as the workhorse used grade. Two practical takeaways: (1) for buyers focused on total-cost-of-ownership over a defined holding period, CW is almost always the better economic choice; (2) the gap narrows significantly in undersupplied markets, where any available CW commands a premium close to the One-Trip range — in those markets the One-Trip becomes the rational choice on value-for-money grounds.

Question 4

When does it actually make sense to pay the One-Trip premium?

Accepted Answer

Three cases where the One-Trip premium is justified, and outside them CW wins. (1) Visible presentation: showroom, customer-facing modular office, branded fleet, conversion to public-facing housing or café — the paint and the visible condition matter, and a CW (even a clean one) will show its use under close inspection. (2) Long-haul maritime ahead: if you're planning 15+ years of certified international shipping, starting at year zero of certified life rather than year 10 changes the economics — you'll get more rotations before re-certification or replacement, and the unit holds residual value longer through its first 10 years (roughly 5% per year as discussed in the new vs used guide). (3) Conversion projects where heavy cutting, welding, insulation and finishing will be done: starting from a clean shell saves rework, avoids structural surprises hidden under old paint, and gives a predictable substrate. Outside these three cases, CW is the correct grade — the One-Trip premium becomes pure aesthetic spend, and for static storage, workshops or modular building it's spend that delivers no functional return.

Question 5

How do I make sure I'm getting the One-Trip or CW grade I'm paying for?

Accepted Answer

The container trade is mostly remote — boxes are bought from depot inventory, often sight-unseen — so the verification chain at the moment of sale carries real economic weight. For both grades, three things should be in the seller's quote and your acceptance: (1) Photos of the actual unit you're buying (not stock photos), showing exterior, interior, floor, and the CSC plate at legible resolution. (2) Inspection report from the depot, naming the grade and the date of inspection. (3) For CW specifically: the next CSC inspection date on the plate, which must be far enough in the future to cover your intended shipping use — if you'll ship within months, any future date works; if you'll ship in 18 months, look for at least that much margin. For any used grade bought at distance, you can also have an independent third party inspect the container on site and issue a counter-report — a service commonly offered by port survey companies. MG-Atlantic operates across all five grades including a steady stock of CW and One-Trip units in the 20DC, 40DC and 40HC formats, with depot photos and CSC inspection details supplied on every quote — and a one-way SOC quote in under 24 hours once the route is confirmed.
