Shipping & documentation
Shipping used cooking oil in a flexitank
Prepare a UCO flexitank shipment with carrier approval, equipment compatibility, payload checks, sampling and receiving arrangements.
Direct answer
A UCO flexitank shipment requires agreement on liquid compatibility, container and flexitank suitability, carrier acceptance, permitted payload and loading/discharge arrangements. Do not treat a typical payload estimate as a guaranteed booking or an equipment approval.
Confirm equipment and cargo compatibility
Give the equipment provider and carrier an accurate material description and the handling conditions. Obtain their acceptance for the planned cargo and route. A technical data sheet cannot replace the specific equipment and carrier checks.
Check container condition, flexitank installation requirements and the loading location’s ability to comply. Establish who inspects the setup and records the equipment and container identifiers.
Validate quantity against the actual route
Permitted payload depends on the equipment, container, carrier and road legs. The site’s indicative 21–23 metric tonne example for a 20-foot flexitank is a planning reference only. Confirm the actual limits before ordering or booking.
Record loaded quantity using the agreed weighing procedure. Do not confuse nominal container capacity, liquid volume and metric tonnes. Clarify how quantity tolerances will be assessed and who supplies the weighing evidence.
Plan unloading before dispatch
Confirm receiving access, compatible connections and pumping arrangements, and any approved handling-temperature instructions. Agree inspection and sampling before loading and keep seals and shipment references linked to the cargo.
Allocate freight and destination handling through the agreed delivery basis. Resolve free-time, delay and equipment responsibilities with the logistics provider before dispatch.
- Cargo accepted by carrier and equipment provider
- Actual payload and route limits checked
- Loading and weighing plan agreed
- Seals and sample references recorded
- Receiving equipment and unloading window confirmed
Buyer questions
Does every flexitank carry 23 tonnes of UCO?
No. Confirm equipment, container and route restrictions. An indicative range is not approval of a payload.
Can loading be booked before receiving arrangements are confirmed?
The receiving equipment and discharge plan should be resolved before dispatch to avoid an unworkable delivery.
Sources and evidence
Primary references support the stated technical definitions. Procurement checklists are editorial guidance, not evidence of a specific lot, shipment or certification.
Confirm laboratory methods, commercial terms and applicable requirements with the buyer and qualified advisers before contracting. No guide establishes stock availability or company certification.
