What's the TPD Regulation, and How Does It Affect Vapes You Buy Online in the UK?

TPD stands for Tobacco Products Directive, the EU law the UK kept as the Tobacco and Related Products Regulations (TRPR). Every retailer that lets you buy vapes online in the UK follows 5 core TPD limits on strength, tank size, and bottle size.

What Is the TPD Regulation and Where Did It Come From?

The Tobacco Products Directive (TPD) started as EU legislation in 2016 to standardise tobacco and vaping products. The UK copied these rules into domestic law as the Tobacco and Related Products Regulations (TRPR) after Brexit. The Medicines and Healthcare products Regulatory Agency (MHRA) enforces TRPR across Great Britain today.

Check the small print on any product before you buy vapes online UK, since a compliant listing always references TRPR or TPD directly. Retailers that skip this detail on nicotine products often sell non-compliant or imported stock.

Which 5 Product Categories Does TPD Regulate?

TPD regulates 5 categories: nicotine strength, tank capacity, refill bottle size, packaging requirements, and ingredient safety. Every legal device and e-liquid sold in the UK meets all 5 categories before it reaches a retailer's shelf. Manufacturers submit product data to the MHRA before any nicotine-containing item goes on sale.

Ingredient safety rules exclude specific banned additives, including diacetyl and vitamin E acetate, from every e-liquid. Packaging requirements demand child-resistant caps and tamper-evident seals on every nicotine bottle. These 5 categories apply equally whether you shop in person or buy vapes online UK-wide.

What's the Maximum Nicotine Strength Allowed Under TPD?

The maximum nicotine strength permitted under TPD is 20mg/ml (2%), and this limit applies to every nicotine type. Nic salts, freebase e-liquids, prefilled pods, and nic shots all share this same 20mg/ml ceiling. Common legal strengths at UK retailers include 3mg, 6mg, 10mg, 11mg, and 20mg.

Any bottle advertised above 20mg/ml is non-compliant and illegal to sell in the UK, regardless of where it ships from. Report a listing above this limit to the retailer, since selling it breaches TRPR directly.

Why Are Vape Tanks and Pods Limited to 2ml?

TPD limits vape tanks and pods to a 2ml (0.07fl oz) maximum capacity to control how much nicotine a device holds at once. This cap reduces the risk of nicotine overexposure from a single refill or leak. Every compliant tank, pod, or cartridge you buy online in the UK meets this 2ml limit.

Some devices work around the 2ml cap using a larger outer tank with a 2ml internal chamber, which remains fully legal. Check the specification sheet for the internal nicotine-holding capacity, not the visible tank size, before you order.

Why Can You Only Buy Vapes Online UK With 10ml Nicotine Bottles?

TPD restricts nicotine-containing e-liquid to bottles of 10ml (0.34fl oz) or smaller at the point of sale. This bottle-size rule does not apply to nicotine-free liquid, which is why shortfills come in 50ml (1.7fl oz) or 100ml (3.4fl oz) sizes. Add a separate nic shot to a shortfill if you want nicotine in a larger bottle.

How Does the 2025 Disposable Ban Fit Into TPD Rules?

The single-use disposable vape ban took effect on 1 June 2025 and sits alongside the existing TPD framework. A legal device must now be rechargeable and refillable, or use replaceable pods, to stay on sale. Every TPD nicotine and tank limit still applies to these rechargeable devices exactly as before.

Retailers pulled every single-use device from shelves and websites the same week the ban started. Most shoppers who once bought disposables now buy vapes online UK retailers stock as prefilled pod kits instead, which meet the same 2ml tank rule.

How Do You Know a Vape Is TPD Compliant When You Buy Vapes Online UK?

Check Packaging Labels

Check the packaging for a nicotine warning label and full ingredient disclosure before you buy vapes online in the UK. A compliant product lists nicotine content, batch details, and a child-resistant cap on every bottle. Missing labels on a nicotine product signal a non-compliant or counterfeit item.

Check MHRA Notification

Check that a product has an MHRA notification number, since every legal nicotine device and e-liquid needs one. Retailers list TPD compliance directly on product pages for prefilled pod kits and bottled e-liquids. Ask the retailer directly if you cannot find this information before you order.

A genuine MHRA notification number appears on the manufacturer's own compliance page, searchable by product name. Cross-check this number if you plan to buy vapes online UK from a retailer you have not used before.
