Dongying Haode Petroleum Technology Development Co., Ltd.

Dongying Haode Petroleum Technology Development Co., Ltd. offers a diverse range of industrial chemicals and bearings that are in demand across oil refining and filtration sectors. Being based in China gives them access to large-scale manufacturing and low-cost production, which helps keep prices competitive. The product range includes specialty materials like silica gel and oxalic acid — commonly used in petrochemical processing — which can be valuable for buyers in refining or chemical treatment. However, no work email, phone, or documents have been verified, which raises concerns about business legitimacy and responsiveness. Buyers should request additional proof of identity and contact details before placing large orders. Without verified communication channels, it's hard to confirm real-time availability or respond to urgent inquiries. This lack of verification is common among smaller or newer suppliers, but it increases the risk of miscommunication or fraud. Always verify the company's credentials before engaging in serious trade discussions.
