Types of inland barges: which vessel fits your cargo?

Types of inland barges: Kempenaar, Rhine vessel and push-tow convoy

The inland shipping fleet is diverse, and each of the types of inland barges has a direct effect on your supply chain. Pick the wrong vessel type, and it can undermine your entire import strategy. Below are the three types you'll run into most often as an importer bringing cargo from Asia into Benelux or NRW.

The Kempenaar/Spits — the flexible specialist. Its limited dimensions get it into places larger inland barges can't reach. What this means for your shipment: ideal for smaller volumes (LCL) or FCL deliveries to regional terminals further inland. You pay for precision and reach, not bulk volume.

The large Rhine vessel — the workhorse for FCL. The backbone of container transport on major rivers like the Rhine, with a capacity of 100 to 400 TEU. What this means for your shipment: the obvious choice for cost efficiency on major corridors like Rotterdam-Duisburg. The condition is a destination at a large inland terminal.

The push-tow convoy — the volume king. A pusher tug with multiple barges moving over 500 TEU combined: barging at industrial scale. What this means for your shipment: the lowest cost per TEU, but only worthwhile for large, constant volumes to a single central hub. Transit time can be longer, since consolidating volume takes time.

Comparison: cost and flexibility per vessel type

Here's a quick cheat sheet to see the differences at a glance.

Why the lowest slot price is often the most expensive option

Now that you know the vessel types, here comes the step that matters most — and where most importers go wrong. They fixate on the "slot price," the price for one container on the vessel. A classic mistake.

The lowest price per container is not the same as the lowest total landed cost. I see it every week: an importer picks the cheapest barge, which sails to a terminal 50 kilometers further from the final destination. Result: the savings on the water evaporate completely into the extra cost of the last-mile truck ride. You see the same trap when comparing freight forwarders: the lowest quote on paper is rarely the lowest bill in practice.

Add the cost of unpredictability on top. A truck looks faster, but anyone who's sat on a jammed highway during rush hour knows better. An inland barge liner service runs on a fixed schedule, with punctuality of over 98%. That predictability is worth money.

"This is why at Cargoplot we show the all-in price with every line detailed, from port to door. No hidden terminal fees, no surprise trucking surcharges. Radically transparent, right down to our margin."

From reactive phone calls to proactive control

Coordinating the ocean vessel, the terminal, customs, the barge, and the final truck is the biggest hidden cost. The traditional process is reactive: the vessel arrives, and the frantic phone calls begin.

The smart approach is proactive, with technology as an ally. Instead of juggling multiple freight forwarders and endless email threads, a digital platform centralizes all of that communication. You move from fragmented chaos to a single dashboard where the whole shipment is visible, from Shanghai to your warehouse door.

The result? Your team no longer has to fight fires — it stays in control. Transit times become predictable, and the risk of handover errors disappears.

Choose your inland barge type based on data, not guesswork

Choosing an inland barge is not an operational detail — it's a strategic decision. Knowing the types of inland barges helps you stop guessing on incomplete data and take back control.

That same logic — look past the lowest price and keep control yourself — is also why, for the ocean leg itself, we usually advise FOB: it lets you choose the carrier yourself for the most expensive, most decisive link in the chain, instead of leaving that choice to your supplier.
