Shanghai Green Sub-Nanoseale Material Cor.,Ltd.

Shanghai Green Sub-Nanoseale Material Cor., Ltd. has been operating since 2004, giving it over 19 years of experience in supplying specialty materials like glass beads, calcium carbonate, and mirror powder — products commonly used in coatings, plastics, and construction. Being based in Shanghai provides strong access to China’s industrial supply chain and major export ports. However, none of the key verification fields — phone, work email, account email, or business documents — are confirmed, which raises concerns about the company’s legitimacy and ability to handle large or long-term orders. Buyers should request additional proof before committing to any purchase, especially for technical or high-value materials where quality and reliability are critical. The lack of verification is common in early-stage or new suppliers, but it's a significant risk when dealing with precision materials that require consistent performance and traceability.
