Some regulatory questions are easy to answer. Others are not, especially when a product sits between categories and does not fit neatly into one legal definition. At CE.way, we recently looked at a product that raised exactly this kind of question: should it be treated as a general consumer product under the General Product Safety Regulation framework, or should it be handled as a cosmetic product under cosmetics legislation?
The product was a semi-cured UV gel nail wrap intended for consumer use. In practical terms, it sat somewhere between a false nail, a nail sticker and a UV gel nail product. It came in a pre-formed shape, was applied directly to the natural nail, and then cured under a UV or LED lamp to create the finished decorative effect. At first glance, that may sound simple. From a regulatory point of view, it was not.
The classification question
The main question was whether the product should be treated as an article or as a cosmetic product. There was a reasonable case for the article route, because the product was supplied in a finished, shaped form. Its size, surface and design were all important to how it was used. In that sense, it looked similar to a decorative nail accessory or an artificial nail product – and it was not a liquid, a cream, nor a powder so it didn’t come in any common cosmetic form, which further made this look like an article case from the start.
At the same time, there was also a strong case for cosmetic classification. The product was applied directly to the nail to change its appearance. It contained a semi-cured gel formulation based on an acrylate system, and it needed UV or LED curing after application. Another important point was that the product did not need a separate adhesive. Its ability to stick to the nail and form the final decorative result depended on the material itself.
That made a real difference. With a traditional false nail, the nail tip may be seen mainly as a shaped object, while the glue performs the adhesive function. Here, the product’s performance depended on the gel material. The composition was not a side detail. It was central to how the product worked.
Even the authorities recognise the grey area
To support the assessment, we asked for external clarification. The response confirmed something regulatory consultants often see in practice: not every product fits neatly into one category.
There were valid points on both sides. On one hand, the product was supplied in its final shape and form, which could support an article classification. On the other hand, it had a cosmetic purpose, changed the appearance of the nail, and relied on its specific chemical composition to adhere and cure in a way that was similar to a traditional UV-cured gel system.
For that reason, the answer was not a simple yes or no. The product needed to be assessed specifically, as such case-by-case assessment and analysis are often required in borderline cases. For us, that is exactly where good regulatory work begins.
Why we chose the cosmetic route
In this case, CE.way decided to classify the product as a cosmetic product. This was not because the other argument was impossible. It was because, after looking at the intended use, method of application, chemical behaviour and consumer exposure, the cosmetic route gave the more suitable and protective compliance pathway.
The product was designed to beautify the nail. It was placed directly on the natural nail. It relied on a semi-cured chemical system that was completed through UV or LED curing, and its adhesion and final performance came from the formulation itself, not only from its pre-formed shape. From a consumer safety perspective, that matters.
Cosmetic regulation gives a specific framework for products used on external parts of the human body, including nails. It also includes clear requirements around prohibited and restricted substances, safety assessment, product information, labelling, responsible person obligations and market surveillance.
For coloured nail products, this is especially important. Pigments and colourants cannot be selected only because they look good. They must be suitable for cosmetic use, meet the relevant purity expectations, and be allowed under the applicable regulatory framework. In other words, the final look is only part of the question. The ingredients used to create that look matter just as much.
By treating the product as a cosmetic product, we chose to look at it through a more safety-focused lens. That meant assessing not only how it looks and functions, but also how its ingredients and application method affect consumer safety.
Borderline products need more than checkbox compliance
Borderline classification is not about finding the easiest route. It is about understanding the product well enough to choose the route that can be properly justified. A semi-cured UV gel nail wrap is not just a sticker. It is not simply a false nail. It is also not exactly the same as bottled UV gel polish. It takes features from several product types, which is why the classification needs proper technical and regulatory analysis.
The assessment needs to consider the product’s intended purpose, where and how it is applied, whether it comes into contact with the human body, and whether its effect is decorative, protective, functional, or a mix of these. It also needs to look at whether the shape or the chemical composition is more important to how the product works, what happens during and after application, which substances are present, what level of consumer exposure can reasonably be expected, and which regulatory framework gives the most suitable safety controls.
The EU Cosmetics Borderline Manual, officially the Manual of the Working Group on Cosmetic Products (Sub-Group on Borderline Products) on the Scope of Application of the Cosmetics Regulation (EC) No 1223/2009 (Art. 2(1)(a)), is the main reference document for these assessments. It is published by the European Commission and regularly updated as new product types emerge. It covers a wide range of grey-area product types, such as adhesives, vial products, nail products, and others, along with practical guidance and worked examples. But even with the manual as a reference, classification is always done case by case. The same product type can land on different sides of the line depending on its formulation, its claims, how it is presented, and what it actually does.
This is why borderline cases cannot be solved by looking only at a product photo or marketing description. They require a full assessment of the product, including formulation, claims, instructions for use, exposure, performance, safety data and any relevant regulatory precedent.
The real role of a consultant in borderline cases
For brands, classification can feel like an administrative step. In reality, it shapes the whole compliance strategy. If a product is treated as a general consumer product, one set of obligations applies. If it is classified as a cosmetic product, the brand must consider cosmetic-specific requirements, including safety assessment, ingredient review, responsible person obligations, product information documentation, labelling and notification requirements where relevant.
This can affect timelines, testing, documentation, ingredient selection, claims, packaging and market access. That is why CE.way takes a cautious and practical approach. We do not look for the lowest regulatory burden. We look for the classification that is technically justified, defensible and aligned with consumer safety.
In this case, because the product’s cosmetic purpose and chemical mode of action were so important to its performance, we considered cosmetic classification the safer and more responsible route.
Why this matters for beauty brands
Beauty innovation often moves faster than regulation. New product formats are constantly entering the market: hybrid nail systems, cosmetic patches, beauty devices used with formulas, semi-cured products, adhesive-free applications and products that combine a physical form with chemical performance.
These products often sit between familiar categories. They may look like accessories, behave like cosmetics and be marketed as beauty products. For brands, this creates both opportunity and risk.
A weak classification decision can lead to incomplete documentation, unsuitable ingredients, incorrect labelling, missed safety obligations or enforcement problems that could have been avoided. A strong classification decision gives the brand a clearer route to market and a better foundation for long-term compliance.
This is why early regulatory assessment is so valuable, especially for innovative products that do not fit neatly into an existing category.
Our view
The most responsible classification is not always the most convenient one. For this semi-cured UV gel nail product, there were arguments on both sides. It had some characteristics of an article because it was supplied in a pre-formed shape. But it also had clear cosmetic characteristics: it was applied to the nail, intended to change appearance, relied on a specific gel composition, adhered without separate glue, and required curing to complete the cosmetic effect.
After assessing the product as a whole, CE.way chose the cosmetic route because it gave the more specific and protective safety framework for the consumer. This is the kind of regulatory judgement that matters in modern beauty compliance and builds consumer trust.
At CE.way, we support cosmetic and non-cosmetic brands through exactly these types of decisions. Whether a product clearly falls under cosmetic regulation, clearly belongs under general product safety rules, or sits somewhere in between, our role is to help brands build a compliance strategy that is technically sound, commercially practical and centred on consumer safety.
Because in the most complex cases, good compliance is not just about knowing the rules. It is about knowing how to apply them.
