Chengrand Research Institute Of Chemical Indust... has been in business since 1965, which is much longer than most modern suppliers — suggesting deep industry experience and possibly strong technical expertise. Their product range includes silicone, fireproofing materials, rubber, seals, and adhesive paper, which are common in industrial and construction applications. However, none of their key verification details — work email, phone, or business documents — are confirmed, which raises concerns about legitimacy and ability to respond to buyer inquiries. This lack of verification is common among older Chinese suppliers who may not have adopted modern digital verification practices. Buyers should treat this as a red flag and request additional proof before placing large orders. While the long history is a strength, it doesn't compensate for missing verification signals that could affect trust and due diligence.
