| Regulatory scope | Nicotine-containing electronic cigarettes and refill containers placed on the EU market are covered by Directive 2014/40/EU, commonly known as the Tobacco Products Directive (TPD). | A flavored pen containing nicotine must be designed and documented as a regulated e-cigarette product for the destination EU member state. | Confirm whether the product is nicotine-containing, nicotine-free, or supplied in both versions, because the applicable obligations can differ. | Required |
| Nicotine concentration | Maximum nicotine concentration: 20 mg/mL, equivalent to 2% nicotine by volume. | Offer EU-ready nicotine strengths at or below 20 mg/mL and keep strength information consistent across the device, packaging, and technical documents. | Check laboratory test results, formulation records, batch specifications, and label declarations. | Required |
| Cartridge or tank capacity | Maximum liquid capacity of a disposable cartridge or tank: 2 mL. | A compact air pen with a controlled 2 mL or lower reservoir is easier to configure for the EU baseline. | Verify the nominal and maximum fill volume using engineering drawings and production inspection records. | Required |
| Refill container capacity | Maximum refill container capacity: 10 mL. | If the product is refillable, supply refill packaging that does not exceed the EU limit and clearly identifies the liquid volume. | Review bottle drawings, net-content measurement, closure specifications, and packaging artwork. | Required |
| Leakage control | Electronic cigarettes and refill containers must be protected against leakage under normal use and during refilling. | Sealed pods, stable airflow paths, secure mouthpieces, and controlled filling interfaces support a cleaner flavored-air experience. | Request leak, pressure, transport, orientation, and repeated-use test records. | Required |
| Child-resistant and tamper protection | Products must be child-resistant and protected against breakage and leakage. Refill containers must also include a child-resistant opening mechanism and tamper-evident protection. | Packaging and refill accessories should be designed as part of the product system rather than added after production. | Check packaging test reports, closure performance, tamper-evident features, and user instructions. | Required |
| Materials and component safety | Under normal use, the device should not release substances in quantities that present a risk to human health. Components include the liquid container, heating element, and materials in contact with the e-liquid. | Flavor consistency should be supported by controlled materials, stable heating components, and documented e-liquid compatibility. | Review bills of materials, food-contact or relevant material declarations, supplier specifications, and chemical risk assessments. | Required |
| Ingredients and emissions information | Manufacturers and importers must provide ingredient information and available emissions data to the relevant authorities before market placement. | Flavor formulations should be traceable by batch, with consistent ingredient naming and supporting technical documentation. | Request the ingredient list, safety data sheets where applicable, emissions testing, and product notification records. | Required |
| Health warning | Nicotine-containing e-cigarette unit packaging must carry the required nicotine health warning in the language or languages required by the destination member state. | Packaging artwork must be localized for each EU market instead of using one unverified multilingual label. | Confirm warning wording, placement, contrast, size, language, and print-control procedures. | Required |
| Leaflet and consumer information | Unit packaging must include relevant instructions, precautions, contact information, ingredients, nicotine content, batch information, and other required consumer details. | A clear leaflet helps global buyers support responsible use, correct charging, storage, refilling, and disposal. | Check the final leaflet against the destination country’s language and labeling requirements. | Required |
| Flavor positioning | The TPD does not create a single EU-wide ban on all e-liquid flavors; however, member states may adopt additional national rules, and products must not make misleading or medicinal claims. | Flavored air pens can offer product differentiation, but flavor availability must be checked separately for every target country. | Screen flavor names, descriptors, advertising claims, and destination-market restrictions before launch. | Market-specific |
| Pre-market notification | Manufacturers and importers generally must submit product information to the competent authority before placing a covered product on the market. The TPD provides a six-month pre-market notification period. | Allow time for product files, translations, laboratory evidence, packaging, and national submission workflows. | Obtain confirmation of the responsible manufacturer or importer, submission status, and applicable national authority process. | Required |
| Battery and charging design | The TPD does not prescribe one universal battery capacity for all electronic cigarettes, but general product-safety and electrical requirements still apply. | Stable output, overcharge protection, short-circuit protection, and clear charging instructions improve safety and buyer confidence. | Review electrical safety tests, battery specifications, protection-circuit documentation, and transport classification where relevant. | Safety-dependent |
| Packaging and recycling | Packaging, batteries, and electrical equipment may be subject to additional EU and national environmental, waste, and producer-responsibility obligations. | A standardized, low-material package can simplify international documentation while supporting sustainability goals. | Confirm applicable producer-registration, battery, WEEE, packaging, and waste-labeling obligations in each destination country. | Market-specific |
| Global market adaptability | EU TPD compliance is an EU baseline and does not automatically prove compliance in non-EU markets. | A modular flavor, pod, label, and firmware strategy can help adapt one platform to different nicotine limits, capacities, and labeling rules. | Prepare a country-by-country regulatory matrix before selecting a global production configuration. | Market-specific |
