I've stated in the past that QA and QC on
eliquids in general is an apparent problem for the industry as a whole. The Chinese(Dekang) have gone to the length , at least, of getting some type of certification's(i.e CE, SGS, RoHS, TUV and Korean FDA - although all non USA, these are reputable worldwide/regional certification entities) and avow that they adhere to manufacturing standards of ISO9001:2008 & Korean GMP(good manufaturing practices-how this compares to US FDA cGMP is up for debate). My point is they've been accredited by independent non-biased certification entities and adhere to some verifiable manufacturing standards.
To my knowledge, no
eliquid manufacturer in the US(other then Johnson Creek's FDA standard 2002 bioterrorism registration- which is not the same thing as FDA product approval) has gone to any length to get their product or process approved by any independent certification entity or analyzed by an independent non-biased lab source. I would also be very interested to see if any US
eliquid manufacturers approach standards such as cGMP in their particular manufacturing process.
It just seems odd to me that , of all countries, the Chinese have one up'd US manufacturing on apparent Quality control/assurance issues in any arena, especially one that is as inherently dangerous as production of a product intended for direct human inhalation.
I would hope this situation will change in the near future, especially with the recent court decision which, at the very least, now seems to lend some legal credence to US e-cig industry as a whole.
