Gray Mackenzie Engineering Services L.L.C.

Gray Mackenzie Engineering Services L.L.C. has been in business since 1862, making it one of the oldest companies in the UAE — a rare longevity that suggests deep industry roots and institutional knowledge. Offering petrochemicals, gum resin, and solvents, the company is well-positioned to serve industrial clients in oil and chemical sectors. However, no phone number, work email, or business documents have been verified, which raises concerns about legitimacy and contact reliability. Buyers should treat this lack of verification as a red flag and request additional proof before placing any orders. While the company's long history is a strong credibility signal, the absence of verifiable contact details makes it harder to trust or engage with directly. In international trade, especially for technical or chemical products, having verified contact points is essential for due diligence and smooth communication.
