TPD Compliance Guide: E-Liquid Regulations in the EU (2026)

What Is the Tobacco Products Directive?

The Tobacco Products Directive (TPD) is Directive 2014/40/EU of the European Parliament and of the Council, and it is the primary legislation governing e-cigarettes and e-liquids across the European Union. Article 20 of the directive specifically addresses electronic cigarettes and refill containers, establishing the baseline requirements that every manufacturer, importer, and distributor must follow before placing products on the EU market.

Understanding TPD compliance is not optional — it is a legal requirement in every EU member state, and non-compliance can result in products being seized, fines, or market bans.

Core TPD Article 20 Requirements

Nicotine and Volume Limits

The directive sets clear limits on nicotine concentration and container sizes:

Maximum nicotine concentration: 20 mg/mL
Maximum refill bottle size: 10 mL
Maximum cartridge/pod capacity: 2 mL

These limits apply to all nicotine-containing e-liquids sold in the EU. Nicotine-free liquids are not regulated under Article 20, which is why shortfill and longfill formats have become popular alternatives (see our article on OEM vs White Label vs Private Label for more on these formats).

Banned Ingredients

The TPD prohibits the following substances in e-liquid formulations:

Diacetyl and acetyl propionyl (diketone flavoring compounds)
Colorings — additives that color the liquid
Caffeine and taurine — stimulant additives
CMR substances — carcinogenic, mutagenic, or toxic to reproduction (classified under CLP Regulation)

Manufacturers must ensure that every ingredient in their formulations has been screened against these prohibitions before submitting for notification.

Packaging Requirements

TPD packaging rules are strict and specific:

Child-resistant closure mechanisms are mandatory
Tamper-evident seals must be present
Health warnings must cover at least 30% of the two largest surfaces of the packaging
The required warning text: “This product contains nicotine which is a highly addictive substance”
A full ingredient list, nicotine content, batch number, and manufacturer details must appear on packaging

Emissions Testing

Every product variant must undergo emissions testing to determine what the user actually inhales when the liquid is vaporized. This includes testing for nicotine delivery, aldehydes, and other compounds released during heating. Each nicotine strength variation requires separate emissions testing.

The EU-CEG Notification Process

Before any e-liquid product can be sold in an EU member state, it must be notified through the EU Common Entry Gate (EU-CEG) system. Key facts about this process:

Notification must be submitted 6 months before the intended market launch
Notification must be submitted to each member state individually where you plan to sell
The submission includes detailed product data: ingredients, emissions data, toxicological data, nicotine dose information, and production process descriptions
Annual reporting is required: sales volumes by brand, product type, and member state

The 6-month waiting period is one of the most significant barriers to market entry for new brands. However, there are legitimate strategies to reduce this timeline — for example, registering a new brand as a sub-brand under an existing registered product line.

Country-Specific Variations

While the TPD sets the EU-wide baseline, individual member states can — and do — impose stricter national regulations:

Country	Additional Regulation
Belgium	Banned disposable e-cigarettes (January 2025)
France	Banned disposable e-cigarettes (February 2025)
Netherlands	Implemented a tobacco flavor ban on e-liquids
Romania	Banned disposable e-cigarettes (January 2026)

These national variations mean that a product compliant with baseline TPD requirements may still be non-compliant in specific markets. Manufacturers must check each target country’s regulations individually.

The EU Battery Regulation

The EU Battery Regulation introduces sustainability requirements that function as a de facto ban on disposable vaping devices. By February 2027, all portable batteries in consumer products must be removable and replaceable by the end user. Since disposable e-cigarettes contain sealed, non-replaceable batteries, they will effectively be prohibited across the entire EU by this date.

What Is Coming: TPD3

The European Commission is working on a revision to the Tobacco Products Directive, commonly referred to as TPD3. Originally expected in Q1 2026, the proposal has been delayed to mid-2026, with the revised directive unlikely to take effect before approximately 2028.

While the final text is not yet available, the revision is expected to address gaps in the current framework, particularly around novel products, flavors, and cross-border online sales.

Tobacco Taxation Directive

Separately, the European Commission proposed a revision to the Tobacco Taxation Directive in July 2025, which would harmonize excise duties on e-liquids across member states. This proposal has not yet been adopted and is still under legislative review.

Compliance Checklist

For manufacturers and brands entering the EU market, here is a practical compliance checklist:

Formulation review — screen all ingredients against TPD banned substances list
Laboratory testing — complete emissions testing for every product variant (see our Quality Control Testing guide)
EU-CEG notification — submit to each target member state, 6 months in advance
Packaging design — ensure child-resistant, tamper-evident, with 30%+ health warnings
Country-specific checks — verify compliance with national regulations beyond TPD baseline
CLP/UFI compliance — register with Poison Centres where required
Annual reporting — set up systems to track and report sales data by country
