Phosagro.com is the official site of PhosAgro, a major Russian fertilizer producer with a domain dating back to 2005. The site has a clean history — no blacklists, no malware reports, and 19 years of web archive records. However, the SSL certificate has expired, which means any data sent to or from the site is not encrypted. That's a serious concern for a company of this scale. While the site is almost certainly not a scam, the broken security is unusual for a legitimate corporate website. Most established companies keep their certificates up to date. If you need to contact PhosAgro, use the phone number listed on the homepage. Check back after the certificate is renewed, or verify the company's contact details through other official channels.
