When the TPD regulations came into effect in May 2016, this caused a big shakeup in the way vape e-liquids would be able to be sold in vape shops.
Long gone are the days of buying any bottle size containing the nicotine strength you required, and this was due to the restrictions on the sizes of e-liquid bottles. The bottles that could be sold with nicotine-containing e-liquid were limited to only 10ml in size and the nicotine content was also restricted making the highest dosage of nicotine 20mg (20mg/ml).
The good news is this saw the beginning of short fill bottles of e-liquid. So what are shortfill e liquids mean I hear you asking?
As the bottle size was not limited for bottles containing nicotine free e-liquid this meant that companies were able to produce the same (if not more) e-liquids but all in bigger bottles. The size of the short fill bottles would differ, company to company but the one thing that stayed consistent was the nicotine that had to be 0mg/ml.
So, the term "short fill bottle" related to the larger bottles of e-liquid which you still see available today at most vape stores. Usually, the sizes of these bottles would be either 30ml, 60ml or 120ml. All of the liquids that come in the short fill bottles would appear to be missing a little bit of e-liquid, but this is intentional. Leaving space within the bottle would allow the user to add “nicotine shots” themselves (if required) to reach the nicotine strength preferred for their ideal vape.
Nicotine shots / Nic Shots also became a staple product within the market, as most e-cigarette users tend to use e-liquid with nicotine.
