29. Nicotine strength
a. The maximum nicotine strength of eliquids allowed to be offered for sale on ECF by Suppliers is 36mg or 3.6%. No liquid of strength higher than this can be specifically offered or specifically mentioned by Suppliers. Trade deals are exempt, within private supplier boards only, as higher strengths are needed for trade bulk mixing. Note that there are shipping restrictions in some countries for toxic materials, which can be obtained by application to your local Postal Service and private shippers, and you are cautioned not to contravene these restrictions.
b. Suppliers can sell whatever strength they wish with the exception of pure nicotine (900mg / 90% and above). Sites that sell pure nicotine will be blocked by ECF. We define 'pure nicotine' as 90% / 900mg/ml or higher.
c. There is a limit on public discussion of 200mg (20%) maximum for mixing discussion, recipes and tutorials, and also in the Classifieds.
d. The use of 'Pure Nicotine' cannot be discussed (in detail) on public forums on ECF (trade forums are exempt) due to the hazard [1] - see Notes below. That is to say, it can be mentioned in passing but not discussed at length especially as regards mixing.
