Shipping costs per kg for big consignments are very reasonable. Ideally we would like a batch size big enough to satisfy the global demand for that particular Reference Material for three years. If resupply of the raw material is likely to be a problem, send enough for six years. We would rather not repeat the manufacturing exercise in less time than that.
Our production is geared up for batches between 500kg and 5000kg. We can do smaller batches, but special pricing will apply.
