Yes, grains can ship in bulk. For container lots, loose grain is poured into a liner bag fitted inside a standard container. For very large volumes, grain moves in the holds of bulk vessels. Flexitanks are not used for grain: they are for liquids.
Most first orders from India still ship bagged. Bulk makes sense when you buy large volumes of one grade and have the equipment to discharge it.
Bulk in containers
A container liner is a large bag shaped to fit a 20 ft or 40 ft container. It is fixed inside the container and filled through a hatch at the door end, often with a conveyor or blower. At destination the container is tipped or the grain is drawn out through a discharge spout.
This avoids the cost of bags and bag handling. It also usually lets you load closer to the weight limit. See how many tonnes of grain fit in a 20 ft container.
- You need a tipping chassis, a pit or a suction system at your end.
- The whole container must be one grade and one lot.
- Fumigation and sampling are harder once grain is loose.
- Any moisture or infestation affects the whole load, with no bags to separate the damage.
Bulk vessels
Large grain trades move in bulk carriers, loaded at ports with grain-handling equipment. This route suits mills and big importers buying many thousands of tonnes at a time. It uses different contracts, surveys and port arrangements from container shipping, and it is rarely the right starting point for a new buyer.
Quality control also changes with bulk vessels. Sampling is done during loading by independent surveyors, and the result applies to a very large quantity. A single problem affects the whole parcel, so the contract terms on quality and weight need to be precise.
Why not flexitanks
A flexitank is a single large bladder fitted inside a 20 ft container and filled with a liquid, such as edible oil, glycerine or some food liquids. It is not designed for dry, flowing solids. For grain, use bags, jumbo bags or a dry bulk liner.
If you also buy oils, flexitank shipping is explained in how edible oil is packed for export.
Choosing bags or bulk
Packing options are compared in what packing is used for grains.
- Bags: easier to inspect, sample, fumigate and sell in part. Suits distributors and mixed buyers.
- Jumbo bags: a middle option for mills with forklifts.
- Container liners: lower handling cost for large, single-grade orders to a plant that can discharge them.
- Bulk vessels: for very large volumes and established buyers only.
