Henan Coal Scientific Research Institute Co., Ltd

Henan Coal Scientific Research Institute Co., Ltd. has been operating since 1999, showing long-term presence in the industrial equipment space. The company specializes in shotcrete machines, which are critical for mining and tunnel construction — a niche with high technical demands. However, none of the key verification fields are active: work email, phone, documents, or account email are all unverified. This raises concerns about legitimacy and ability to communicate directly with buyers. In international trade, unverified contact details can delay orders or lead to miscommunication. Buyers should request additional proof, such as a business license or a recent invoice, before placing large orders. While the company's long history is a positive, it must be balanced with the lack of verifiable contact information.
