Agreed characteristics
Grade, sulphur content, density, test methods and acceptance criteria are defined in a technical specification attached to the contract.
The right product.
A precise specification.
Harper’s commercial development focuses on diesel and industrial fuel oil. Every requirement is qualified before a proposal: a commercial product name alone does not define a specification.
Demand determines volumes
First lot, frequency and forecast programme are assessed with the buyer. This website does not advertise available inventory or committed volumes.
Documented quality
The contract must define sampling, independent inspection, quality and quantity certificates, and the points at which checks take place.
