TPD Explained: What Every New Vaper Needs to Know
If you are new to vaping in the UK or Europe, you might have noticed some interesting things about the products you buy. Your e-liquid bottles are always 10ml or less. Your vape tank never holds more than 2ml. The nicotine strength never goes above 20mg. Have you ever wondered why these specific limits exist?
The answer lies in something called TPD, which stands for the Tobacco Products Directive. Understanding TPD is essential for every new vaper because it affects what products you can buy, how they are packaged, and what safety standards they must meet. In this comprehensive guide, we at UK Vape Deals will walk you through everything you need to know about TPD compliance. By the end of this article, you will understand why these rules exist and how they actually protect you as a consumer.
What Exactly is TPD?
The Tobacco Products Directive is a set of regulations created by the European Union in 2014. These rules came into full effect in May 2016 and were designed to regulate tobacco and nicotine products across all EU member states. The directive covers traditional tobacco products like cigarettes, but Article 20 specifically addresses electronic cigarettes and e-liquids.
When the UK was part of the European Union, these rules applied automatically. After Brexit, the UK government decided to keep these regulations in place under a different name. In the UK, we now follow the Tobacco and Related Products Regulations, commonly known as TRPR. However, the rules remain essentially the same as the original TPD guidelines. The main goal of these regulations is to ensure consumer safety, maintain product quality, and provide clear information to users. Whether you are buying from UK Vape Deals or any other reputable retailer, the products (prefilled pod kits & pods) you purchase must meet these strict standards.
The Key Rules You Need to Know
Understanding the specific requirements of TPD will help you make informed decisions when shopping for vaping products. Here are the main rules that affect your everyday vaping experience.
E-Liquid Bottle Size Limits
One of the most noticeable TPD rules is the restriction on e-liquid bottle sizes. Any e-liquid that contains nicotine can only be sold in bottles of 10ml or smaller. This is why you will never find a 30ml or 50ml bottle of nicotine e-liquid in any legitimate UK vape shop.
This rule exists primarily for safety reasons. Nicotine can be harmful if consumed in large quantities, and smaller bottles reduce the risk of accidental poisoning or overconsumption. The 10ml limit also makes it easier for users to track their nicotine intake over time. At UK Vape Deals, all our nicotine e-liquids come in compliant 10ml bottles with proper safety features and labeling.
Maximum Nicotine Strength
TPD regulations cap the maximum nicotine concentration at 20mg per ml, which is sometimes written as 2.0% nicotine. You will not find any legal nicotine e-liquid in the UK with a higher strength than this.
This limit was set based on research into nicotine absorption and safety. The 20mg limit is considered sufficient for most smokers transitioning to vaping while remaining within safe consumption levels. If you have seen videos or heard about vapers in the United States using 50mg nicotine products, you should know that such products are illegal in the UK and EU. Steer clear of any seller offering nicotine strengths above 20mg, as these products are not regulated and could be dangerous.
Tank and Pod Capacity

Your vape tank or pod cannot hold more than 2ml of e-liquid under TPD rules. This is another safety measure designed to limit nicotine exposure in a single session. While 2ml might seem small, especially if you are using a powerful device, it is the legal maximum for any refillable tank or pre-filled pod. Some vapers find this limit frustrating, especially those who vape frequently throughout the day. However, many modern tanks are designed to make refilling quick and easy, minimizing any inconvenience.
Childproof Packaging
All e-liquid bottles must feature child-resistant caps and tamper-evident seals. This is one of the most important safety features required by TPD. Nicotine is toxic, especially to children, and these packaging requirements help prevent accidental ingestion. When you receive your order from UK Vape Deals, you will notice that all bottles have push-and-twist caps that are difficult for young children to open. The tamper-evident seal also ensures that you know your product has not been opened before reaching you.
Health Warnings
Every e-liquid bottle and vape product must carry a specific health warning. The required text reads: “This product contains nicotine which is a highly addictive substance.” This warning must cover at least 30% of the front and back of the packaging. While this might seem obvious to experienced vapers, these warnings are important for people who are new to nicotine products. They serve as a constant reminder that nicotine is addictive and should be used responsibly.
Banned Ingredients
TPD prohibits certain ingredients from being used in e-liquids. These include vitamins, caffeine, taurine, and other additives that might suggest health benefits. Coloring agents are also restricted unless they are necessary for the product. These restrictions exist because there is limited research on the effects of inhaling these substances. By keeping e-liquids simple, regulators aim to minimize unknown health risks.
The Notification Process for Manufacturers
Before any vape product can be sold in the UK, manufacturers must go through a rigorous notification process. They must submit detailed information to the Medicines and Healthcare products Regulatory Agency, known as MHRA, at least six months before the product goes on sale.
This notification must include laboratory test results, toxicology data, ingredient lists, and details about nicotine delivery. The MHRA reviews this information to ensure that products meet safety standards before they reach consumers. This process is one of the reasons why buying from reputable retailers like UK Vape Deals is so important. When you shop with us, you can be confident that every product has gone through proper testing and notification procedures.
How TPD Protects You
While some vapers view these regulations as restrictive, TPD actually provides significant benefits for consumers. Here is how these rules protect you.
Quality Assurance
Before TPD, the vaping market was largely unregulated. Anyone could mix e-liquids in their kitchen and sell them online. There were no requirements for testing, labeling, or ingredient disclosure. TPD changed all of this by establishing minimum quality standards that all products must meet.
Consistent Products
TPD ensures that what you see on the label is what you get in the bottle. Nicotine strengths must be accurate, ingredients must be listed, and batch numbers allow for traceability. If there is ever a problem with a product, manufacturers can quickly identify and recall affected batches.
Safer Devices
TPD also includes requirements for the devices themselves. Tanks must not leak when refilled, and there are standards for how devices deliver nicotine. These requirements have pushed manufacturers to improve their products and eliminate many of the issues that plagued early vaping devices.
What About Shortfills and Nic Shots?

If you have been exploring the vaping market, you might have come across terms like shortfills and nic shots. These products exist as a creative solution to the 10ml nicotine e-liquid limit. A shortfill is a larger bottle of nicotine-free e-liquid, typically 50ml or 100ml, that is not completely full. Because it contains zero nicotine, it does not fall under the 10ml restriction. The empty space in the bottle is designed to accommodate nic shots, which are small 10ml bottles of unflavored nicotine base.
By combining a shortfill with one or more nic shots, you can create a larger quantity of nicotine e-liquid at your preferred strength. This method is completely legal and allows vapers to enjoy more e-liquid without buying numerous 10ml bottles. At UK Vape Deals, we offer a wide range of shortfills and nic shots, making it easy for you to mix your perfect vape juice at home.
How to Spot Non-Compliant Products
Unfortunately, not every product on the market is TPD compliant. Illegal vapes and e-liquids do circulate, often through social media sellers or unauthorized websites. Here are some warning signs to watch for. Be suspicious of any nicotine e-liquid sold in bottles larger than 10ml. If someone is selling a 30ml bottle of nicotine juice, it is not compliant with UK law. Similarly, any product claiming to have more than 20mg nicotine is illegal in the UK.
Products without proper health warnings or those with unprofessional labeling should also raise concerns. Legitimate products will always have clear ingredient lists, batch numbers, and manufacturer information. When you shop at UK Vape Deals, you never have to worry about product legitimacy. We only stock TPD compliant products from reputable manufacturers, ensuring your safety and satisfaction with every purchase.
Conclusion
TPD regulations might seem complicated at first, but they exist to protect you as a consumer. By understanding these rules, you can make smarter purchasing decisions and avoid potentially dangerous non-compliant products.
