Well, I have a couple. These apply to not only you but to any other vendors that follow suit with certifying standard work practices. Basically, certifying your working standards does not necessarily guarantee quality in all aspects. I don't mean that as an insult or in any way negative to your business, just mentioning it for discussion
Where I work, we have more certifications and standards than any one person can keep track of, but many of them can still be adhered to completely and result in a product that doesn't pass final QC.
On to my questions (and again, this is not just for you and in no way is meant to be an attack, but just something to think about/discuss for all vendors):
Do your standards cover the allowed percentages of potentially hazardous chemicals in the finished product? And which ones?
Min and max quantities of all non-hazardous components for QC purposes (consistency of product)?
Do they cover practices concerning hygiene?
Packaging processes to avoid contamination at that late stage?
These are the sort of things that I think the general vaper wants to know, without giving away trade secrets of course, and I applaud you for implementing standards in this way
That's just my
