The short answer

Imp Jar shortfills and nic shots comply with the UK Tobacco and Related Products Regulations 2016, which set strict requirements for child-resistant packaging, maximum nicotine strength, ingredient testing and labelling. Used and stored correctly, by adults aged 18 and over, they are a regulated consumer product. As with any nicotine containing item, sensible handling and storage matters, particularly around children and pets.

What UK regulation requires

Under TRPR 2016, any nicotine containing e-liquid sold in the UK, including the nic shots used to mix Imp Jar shortfills, must be capped at a maximum strength of 20mg per ml, supplied in child-resistant and tamper-evident packaging and carry clear health warnings and ingredient information. These rules exist specifically to limit accidental exposure and ensure consistent product safety across the market.

Storage best practice

Keep all e-liquid, mixed or unmixed, out of reach of children and pets at all times, ideally in its original labelled container with the cap fully tightened. Store bottles in a cool, dry place away from direct sunlight and heat sources, which also helps preserve flavour quality for longer.

Storing a partially used bottle correctly also affects how it tastes over time, see our guide on how long a 50ml shortfill lasts.

Safe handling when mixing

Step Why it matters
Mix over a clean, dry surface Limits spills and makes cleanup straightforward
Wipe any spilled liquid immediately Reduces unnecessary skin contact with nicotine
Wash hands after handling nic shots Standard precaution before eating or touching your face
Reseal bottles fully after use Maintains the child-resistant function of the cap

None of this is complicated, it mirrors the basic care most households already take with cleaning products or medicines kept at home.

Common questions about safety

What should I do if e-liquid is accidentally swallowed?

Seek medical advice immediately, taking the bottle with you so medical staff can see the exact product and nicotine strength involved. Do not wait to see if symptoms develop.

Is it safe to leave a mixed shortfill bottle assembled long term?

Yes, provided it is kept sealed, stored correctly and out of reach of children, in line with the same storage advice that applies to any e-liquid.

Are Imp Jar products tested before sale?

All nicotine containing products sold in the UK, including nic shots used with Imp Jar shortfills, must be notified to the MHRA and meet TRPR 2016 testing and labelling requirements before they reach retailers.
