Overview

EN 18050:2025 (CEN) specifies the user information that producers must provide with vaping products, cartridges, prefilled containers and related accessories. It covers what must appear on outside packaging, unit packets, product information leaflets or online content supplied with the product. The standard aims to harmonize minimum information for safe and correct use across European markets while recognising that national regulations (e.g., TPD, CLP) may take precedence.

Key topics and requirements

• Scope and audience: Applies to vaping products, cartridges, prefilled containers, refillable systems and accessories; intended for producers, manufacturers and suppliers.
• Presentation and language: User information must be legible, irremovable if printed on the product, and provided in the official language(s) of the country of sale. Presentation should follow EN IEC/IEEE 82079-1 principles.
• Packing list: Detailed list of enclosed contents and relevant specifications (including electronic safety information where applicable).
• Ingredients and labelling:
  • Nicotine concentrations reported in mg/mL.
  • If nicotine salts are used, the information must state the presence of nicotine salts and report nicotine based on the nicotine moiety, not total salt weight.
  • Acids used to form nicotine salts must be listed in the ingredients.
  • Requirements for ingredient information cross-reference EN 17648 (e-liquid ingredients).
• Usage instructions:
  • Full instructions for activation, operation, maintenance, cleaning, storage and disposal.
  • Charging instructions (cable/adaptor specs, connection, charging feedback such as lights or messages).
  • Cartridge docking and removal procedures for closed systems.
  • Filling, priming, waiting times and spill handling for refillable reservoirs.
  • Compatibility guidance for PG/VG ratios, power settings and nib dimensions for refill bottles.
  • Instructions for connected devices, including app setup and pairing.
• Safety and compliance: Product instructions should conform to EN IEC 60335-1 and EN IEC 60335-2-120:2025 for electrical appliance safety. Readability and accessibility of instructions are emphasised.

Practical applications - who uses this standard

• E-liquid and device manufacturers - to design compliant packaging, leaflets and online user guides.
• Regulatory and compliance teams - to align labelling and documentation with EU harmonised practice.
• Product designers & technical writers - to produce clear, legally sound instructions for use.
• Retailers and importers - to verify that products meet information requirements for sale.
• Testing and certification bodies - for conformity checks against documented user information.

Introduction
User information is a set of instructions that come with vaping products, cartridges, prefilled
containers, and accessories. The user information can be documented on a pull-out book known
as a product information leaflet, adhered to the product itself in the case of prefilled containers,
or detailed on the packaging. Additionally, a reference can be provided that directs the consumer
to the user information online.
This document establishes the instructions that can be provided to the consumer, such as the
instructions for the use and storage of the product as part of these user information details. The
recommendations given in this document are relevant to most product types currently available,
as well as to those that will be developed.
NOTE 1 This document can provide state of the art guidance; however, in cases where national
regulations currently exist, said regulations can take precedence over this document. This document can
provide supplementary information in addition to national regulations.
NOTE 2 Legal requirements with regard to labelling and nicotine content are dictated by the TPD and
CLP legislation. The aim of this document is to bring consistency and a minimum standard across different
legislative regimes as well as supplement and aid in the implementation of said regulations.
