Diesel purchases fail most often on identity, specification and delivery detail, not on slogans. Verify those points before a discussion becomes a transaction.
Know who you are dealing with
Check the company name, country and registration details the counterparty gives you against a public register where one exists. For ORION-T LTD, the Kazakhstan register lists BIN 060440008872, Karaganda, with registration in 2006. Use the contact details published on this website when you want this company, and treat unexpected account or email changes as something to confirm by phone.
Know the product the destination will accept
Ask for the specification that will govern the parcel. Sulfur, density, cetane and cold-flow performance should come from that specification, not from a general page. See what EN590 does and does not specify by itself and the EN590 diesel page. If the discharge terminal has its own quality rules, get them in writing.
Know the operational points
Confirm quantity and any tolerance, the loading or discharge place, the delivery basis, and how quality and quantity will be inspected. Agree which commercial documents the transaction will use before money moves. Do not send funds on the strength of a website page or an informal message.
When those points are clear, submit the diesel requirement for review. Availability is not guaranteed by this article.
