Yes, you can buy bentonite either way. Crude lumps and coarse grades for processors often ship loose in bulk carriers. Processed powder and granules usually ship in small bags or one-tonne jumbo bags, packed in containers or loaded as break bulk.
The right choice depends on your volume, the grade, your receiving facilities and how sensitive the product is to moisture.
Bulk shipments
Bulk suits buyers who take full or part shiploads and process the clay themselves. Typical examples are grinding plants, pelletising plants and large foundry sand suppliers. The clay ships as dried lumps or coarse material, loaded by grab or conveyor at ports such as Deendayal (Kandla) and Mundra.
Bulk needs a buyer with a suitable berth, unloading gear and covered storage. Moisture control is critical, because wet clay adds weight and can become sticky and hard to discharge. The shipper must also declare the cargo correctly under the IMSBC Code, the international code for solid bulk cargoes. Ask how the clay is stored at the port before loading. Stockpiles left uncovered in a late shower can pick up moisture that you will then pay freight on and struggle to discharge.
Bagged shipments
- Small bags of 25 kg or 50 kg suit powder and granules for retail, distribution and smaller users, often on pallets.
- Jumbo bags of about one tonne suit industrial users with forklifts or cranes, such as drilling contractors and foundries.
- Printed retail bags or boxes suit cat litter and some consumer grades, which bring branding and labelling into the order.
- Bags should be woven polypropylene or multi-wall paper, with a liner where moisture matters.
Containers and break bulk
Bagged bentonite usually travels in 20-foot containers. Bentonite is dense, so a box reaches its weight limit before it is full. Check the legal road weight in your country before agreeing a load, because it is often lower than the sea limit.
Large bagged orders can also go as break bulk, with bags or jumbo bags stowed directly in the ship's hold. That can suit buyers near a port with good handling, but bags face more handling damage and moisture risk than in a sealed container. Our article on freight options for bulk minerals compares the routes.
Packing checks
Most complaints about bagged bentonite come from packing, not the clay. Ask for bag strength, liner and stacking details in the contract. Check that each bag shows the grade, lot number and net weight. Have the bags inspected for torn seams, short weight and dampness before loading.
Containers should be clean, dry and free of odours, especially for litter grades. Our guide to common complaints with bulk mineral shipments lists the problems to watch for.
