TPD Imported E-Liquid Checklist: Nicotine Strength, Pack Size and Child Safety

Quick answer: before imported nicotine-containing e-liquids, refill containers, pods or devices are listed for sale in Great Britain, check the legal limits, packaging and notification evidence against official sources, not only against supplier sales copy.

This guide is for adult-facing UK importers, wholesalers and retailers who need a practical goods-in checklist. It covers nicotine concentration, container size, tank or cartridge capacity, child-resistant and tamper-evident packaging, labelling, ingredients, product notification and record keeping. It does not provide legal advice and it does not make safety or health-benefit claims.

The angle matters because imported stock can look compliant at a glance while still leaving gaps: a 20mg/ml label with an oversized refill bottle, a compliant-looking pod kit without clear notification evidence, packaging claims that do not match the unit pack, or supplier paperwork that does not identify the exact product variant.

Use this alongside our wider compliance cluster: UK vape laws in 2026, vape WEEE compliance and NI to GB vape movements and VPD checks.

Start with the official Great Britain consumer-product rules. GOV.UK guidance says e-cigarette tanks are restricted to no more than 2ml, nicotine-containing refill containers for sale are restricted to no more than 10ml, and e-liquids are restricted to a nicotine strength of no more than 20mg/ml. It also says nicotine-containing products or their packaging must be child-resistant and tamper-evident, with labelling requirements and warnings.

For imported stock, turn those limits into a receiving checklist. Do not accept "TPD-ready" or "UK-compliant" as a substitute for line-by-line evidence. Match the paperwork to the product name, flavour or variant, nicotine strength, bottle size, pack size, batch or lot reference where available, and the party responsible for placing the product on the market.

MHRA's retailer and producer advice is especially useful at goods-in stage because it states that the nicotine concentration and size-of-presentation requirements apply to products sold to end consumers, irrespective of whether the end consumer intends to modify the product.

The three numbers that should appear in every imported-liquid check are 20mg/ml, 10ml and 2ml.

These are not buying-guide preferences. They are compliance thresholds described in GOV.UK and MHRA guidance. A retailer should therefore record the checks before stock is listed online, put into a display, or moved to branch inventory.

Imported products deserve extra care because packaging conventions differ by market. A product made for another country may use a larger bottle, different warning layout, different pack language or a device format that does not map neatly to the Great Britain shelf. Do not assume a supplier's UK-facing catalogue page proves every delivered variant matches the UK rules.

GOV.UK guidance says nicotine-containing products or their packaging must be child-resistant and tamper-evident. Directive 2014/40/EU Article 20 sets the EU framework for electronic cigarettes and refill containers, including child- and tamper-resistant packaging and refill mechanisms designed to avoid leakage.

The practical mistake is treating "child-resistant" as a label phrase rather than a control. Importers and retailers should keep supplier declarations, packaging specifications or other evidence in the product file. Staff receiving stock should check the physical pack: seal intact, warning information present, bottle cap or unit-pack mechanism consistent with the file, and no obvious mismatch between sample paperwork and delivered stock.

A good compliance note is short but specific: "SKU checked on arrival against supplier pack file; unit pack sealed; nicotine strength and bottle size match invoice and specification; retained evidence in product folder." That kind of note is more useful than a generic "TPD checked" tick box.

The Tobacco and Related Products Regulations 2016 require a producer who supplies or intends to supply electronic cigarettes or refill containers to notify the Secretary of State in accordance with the regulations. In practice, a retailer buying imported stock should know who the producer or importer is for the Great Britain market and keep evidence that the exact product line has been handled through the notification route.

This is where imported stock often becomes messy. A supplier may provide a brand-level statement, but the retailer needs variant-level confidence: flavour, strength, bottle or pod format, pack size and device configuration. If the evidence only covers a different strength or older pack, it should not be treated as evidence for the delivered SKU.

Retailers do not need to turn every buyer into a regulatory lawyer, but they do need a repeatable escalation path. If branch or ecommerce teams cannot match the product to a current compliance file, the stock should move to a hold queue rather than straight to sale.

GOV.UK ingredient guidance links nicotine-containing liquids back to TRPR requirements and says producers must ensure that nicotine-containing liquid in electronic cigarettes and refill containers does not contain additives listed in Regulation 16 and, except for nicotine, only includes ingredients that do not pose a risk to human health in heated or unheated form.

For a retailer, the realistic check is not laboratory verification. It is documentary discipline. Make sure the supplier's product file covers ingredients and formulation; watch for claims about vitamins, caffeine, taurine, colourings or other features that official guidance flags; and avoid adding marketing copy that turns a compliance check into a health or lifestyle claim.

Be especially careful with imported flavour and packaging descriptions. Adult product information can say what the flavour family is in plain language. It should not lean into sweet-shop language, youth-coded imagery, cartoon-like presentation or unsupported claims about being clean, safe, healthy or risk-free.

The strongest workflow is boring by design. It gives buying, goods-in, ecommerce and store teams the same stop/go rules.

This also protects ecommerce teams. If a product is not cleared at goods-in, the product page should not go live with placeholder copy. If it is cleared, the page should use factual specifications and neutral service information, not promotional claims that imply the product is safer, healthier or suitable for non-smokers.

Imported-liquid checks do not sit alone. GOV.UK says the ban on selling or supplying single-use vapes came into force on 1 June 2025. The Tobacco and Vapes Act 2026 is now on legislation.gov.uk and sits beside existing product standards, notification duties and future powers.

For retailers, that means a compliant imported nicotine liquid file is only one part of the control stack. The same business may also need WEEE and battery handling, Vaping Products Duty preparation, age-of-sale controls, advertising-rule review and future licensing readiness. Keep those workstreams separate in the file so one passed check does not imply everything else is cleared.
