Yunnan Petroleum & Chemical Group.

Yunnan Petroleum & Chemical Group. has been operating since 1960, which is much longer than most modern chemical suppliers — this suggests deep industry roots and likely strong operational stability. Their product range includes phosphoric acid and fertilizers, which are key inputs for agriculture and industrial use, making them a relevant supplier for buyers in farming or manufacturing sectors. Being based in China, they have access to large-scale production and supply chains, especially in the southern region where chemical processing is well established. However, none of their verification details — including documents, work email, phone, or account email — are confirmed, which raises a red flag for buyer trust and due diligence. Without verified contact or business documents, it's hard to verify their legitimacy or respond to urgent inquiries. Buyers should request additional proof before placing any large orders or sharing sensitive requirements.
