Ist mistralni.co.uk sicher?

I've ordered products from Mistral three times now and found them completely reliable, so I'm surprised to see that it's got an 'orange' WOT rating. I'm even more surprised to see that LegitScript has seen fit to designate it as a 'rogue pharmacy' as this company is not a pharmacy. It sells chemicals, not prescription drugs. LegitScript defines a pharmacy as follows: "A website is designated by LegitScript as an Internet pharmacy website if the website facilitates the sale or dispensing of a prescription drug or medical device, either via the website or by directing the Internet user to another website or pharmacy." I fail to see how Mistral chemicals comes under that definition - it doesn't sell prescription drugs, nor does it sell medical devices. It sells things like bulk bicarbonate of soda, sodium carbonate, and so on.
