Chongqing Yuneng Oil Refinery Plant Mfc Co

Chongqing Yuneng Oil Refinery Plant Mfc Co is a long-standing supplier, having operated since 1997 — a strong indicator of stability and experience in the oil refining sector. Their product range includes machine oil purifier, oil residue, oil paper, used oil, and electric testers, which suggests they serve both industrial maintenance and recycling markets. Unlike many new suppliers, this company has decades of operation, which can build trust with buyers looking for reliable, consistent quality. However, none of their key verification fields — work email, phone, account email, or business documents — are verified, which raises concerns about legitimacy and contact reliability. Buyers should treat this as a red flag and request additional proof before placing large orders. Without verified contact details, it's hard to confirm real-time communication or respond to urgent inquiries. This lack of verification is common among older Chinese suppliers who may not prioritize digital transparency, but it increases risk for international buyers.
