Duncan Sterling International

Most oil and natural gas suppliers based in the UK have strong verification of contact details and business documents to build trust with international buyers. Duncan Sterling International lacks verified work email, phone, and business documents — which raises concerns about legitimacy and responsiveness. While operating since 2012 shows stability, the absence of verification makes it harder for buyers to confirm the company's real-world operations. Buyers should request additional proof, such as a company registration or a recent invoice, before placing any orders. This lack of verification is common among smaller or newer energy suppliers, but it increases risk when dealing with high-value commodity trades. Without clear contact validation, coordination and contract negotiation become more difficult and time-consuming.
