How Much Rice Fits in a Container: 20ft vs 40ft
A 20ft container holds 25 tonnes of rice and a 40ft holds 27 tonnes. Why the bigger box carries barely more, and how to size your first order.

Short answer
A 20ft container holds 25 metric tonnes of rice, which is 500 bags of 50 kg. A 40ft container holds about 27 tonnes, only two tonnes more, because rice is dense enough to reach the container's weight limit long before it fills the space. For rice, the 20ft is almost always the more economical box.
1. The numbers
| Container | Rice capacity | 50 kg bags | 25 kg bags |
|---|---|---|---|
| 20ft standard | 25 tonnes | 500 | 1,000 |
| 40ft standard | 27 tonnes | 540 | 1,080 |
| 40ft high cube | 27 tonnes | 540 | 1,080 |
2. Why a 40ft holds barely more than a 20ft
This is the single most useful thing to understand before you order, and it catches out buyers who assume double the length means double the load.
- A container has two limits: how much space is inside, and how much weight it may legally carry. Rice hits the weight limit first.
- A 20ft container has a payload limit around 28 tonnes, and 25 tonnes of rice fills that with room to spare in volume terms.
- A 40ft container is twice as long but its payload limit is only around 30 tonnes, because the limit is set by road and handling rules rather than the box itself.
- The result: you pay for a much larger container and carry two extra tonnes. For rice, two 20ft containers beat one 40ft almost every time.
- A high cube 40ft adds height, not payload. It makes no difference to rice at all.
3. Sizing your first order
One 20ft is the practical minimum
Twenty-five tonnes is the smallest quantity that ships economically. Below a full container you are paying groupage rates and sharing a box, which adds cost, delay and handling risk to a food product.
Match bag size to your market
Fifty kilogram bags are standard for wholesale and re-bagging. Twenty-five kilogram bags suit distributors selling on directly. Smaller retail packs reduce the tonnage that fits, because packaging takes up weight and space.
Budget the whole landed cost, not the rice
To the CIF price add destination port charges, import duty, clearance and inland delivery. These are yours under every Incoterm and are the usual reason a first import comes in over budget.
4. VGM — the declaration without which nothing sails
Verified Gross Mass is a safety-of-life-at-sea requirement, not paperwork you can catch up on later.
- SOLAS Regulation VI/2 has required a verified gross mass for every packed container worldwide since 1 July 2016. Without it, the container is not loaded onto the vessel.
- VGM is the total weight: the rice, all bags, dunnage and securing material, plus the empty container's own tare weight — not just the cargo.
- The shipper named on the bill of lading carries the legal responsibility, even where a forwarder or the packing facility does the weighing and files on their behalf.
- It must be submitted sufficiently ahead of loading. A late VGM is one of the commonest reasons a booked container rolls to the next sailing, which on a weekly service costs a week.
- Ask your exporter to confirm VGM submission alongside the bill of lading. It costs nothing to ask and it is a quick test of whether they have shipped before.
5. Loading and condition on arrival
- Ask for a container inspection before loading. A box that previously carried chemicals or has a damaged seal is not fit for food and this is checked visually, not assumed.
- Dunnage and kraft paper lining protect against condensation, which is the main cause of damage on a long sea leg into a humid port.
- Confirm the fumigation is done before or at loading and that the certificate matches the container number on the bill of lading.
- Ask for photographs of the loaded container and the seal number. It costs the exporter nothing and gives you evidence if there is a dispute at the other end.

Frequently asked questions
How many 50 kg bags of rice fit in a 20ft container?
Five hundred bags of 50 kilograms, which comes to 25 metric tonnes. This is the standard full container load for rice and the quantity most Indian exporters quote against. In 25 kilogram bags the same container takes 1,000 bags for the same total weight.
Should I order a 40ft container instead of a 20ft?
For rice, usually not. A 40ft carries about 27 tonnes against the 20ft's 25, because rice reaches the container weight limit before filling the space. You pay considerably more for the larger box and gain two tonnes. If you need more than 25 tonnes, two 20ft containers normally cost less than one 40ft.
Can I order less than a full container of rice?
It is possible through groupage, where your cargo shares a container with other shipments, but it rarely makes sense for rice. You pay a higher rate per tonne, transit takes longer, and your food product is handled more often and stored alongside cargo you did not choose. One 20ft container is the practical minimum.
Does the rice grade change how much fits in a container?
Only slightly. Basmati is a longer, lighter grain than most non-basmati varieties, so a container of basmati can gross out marginally lower than parboiled rice. The difference is small enough that 25 tonnes in a 20ft remains the working figure across grades for quoting and budgeting.
What is VGM and do I need to worry about it as the buyer?
Verified Gross Mass is the total weight of the packed container including bags, dunnage and the container tare, required under SOLAS rules since 2016. Without it the box is not loaded. The legal duty sits with the shipper named on the bill of lading, so it is your exporter's job — but a late VGM rolls your container to the next sailing.
