Beijing North Tianyu Tongli Engineering & Mechanical Co.,Ltd.

The lack of verification on work email, phone, and business documents raises concerns about identity and legitimacy — buyers should request additional proof before placing large orders. While the company is based in China, a major manufacturing hub for heavy machinery, the absence of verified contact details makes it harder to confirm real-time communication or responsiveness. Without verified documents, it's difficult to assess the company's legal standing or track record with international buyers. Buyers should verify the company's registration and request samples or references before committing to any purchase.
