Most castor derivative plants prefer orders of at least one full 20-foot container. Many will accept smaller orders of a few pallets for standard products such as hydrogenated castor oil and 12-HSA, especially from stock.
Special grades, such as micronised powders or polyols made to your hydroxyl value, usually need a full production batch. That batch size is set by the plant's reactor.
What decides the minimum
- Batch size: a reactor or hydrogenator runs a fixed volume, and the plant must sell all of it.
- Stock: standard grades made for many buyers can be sold in smaller lots.
- Packing: custom bags, labels or drum colours add set-up work.
- Cleaning: changing grades on a line means cleaning time and some lost product.
- Export paperwork: a small lot needs the same documents as a full container.
- Seed and oil markets: when feedstock is tight, plants favour larger, regular orders.
How to buy less than a container
If you need a small volume, combine several products from one plant into a mixed container. For example, you might take HCO, 12-HSA and castor oil in one load. Or take a standard grade from stock while you qualify the plant.
Less-than-container shipments are possible but add handling and risk. Liquids in drums travel more safely in a full container that you control.
Start with samples, then a trial lot before committing to regular volumes. Our guide on what a trial batch is and how large it should be explains the steps. For general MOQ logic across chemicals, see MOQs from Indian chemical manufacturers.
A plant's MOQ is often negotiable once it sees a clear forecast. Share your expected annual volume and how often you will order.
Shared container and stock options
Some plants keep stock of standard grades at the factory or at a port warehouse. Buying from stock lets you take a smaller lot, but check the manufacturing date, because older lots have less shelf life left.
If you buy several castor products from different plants, a consolidated container can work. Each plant delivers to one loading point, and the cargo is checked and loaded together. This needs careful coordination of documents and lot numbers, and someone at loading to check each delivery.
Ask each plant to state its MOQ in writing for each product and form. A plant that accepts small lots on one grade may not do so for another.
Sample sizes
Samples are a separate matter from MOQ. Most plants will send a laboratory sample of a few hundred grams to a kilogram for standard grades. For a plant trial you may need tens of kilograms, which some plants charge for or supply only once you share your expected volumes. Agree sample size and form at the start, so the sample matches what you will buy.
