Packaging labels and instructions for use: how to interpret information on personal wellness products

Packaging labels and instructions for use: what information to actually look for

Packaging labels are not decoration. They help identify the product, the manufacturer, the composition, the shelf life and any restrictions on use. A good online store shows the essential information before the order and does not leave it to the packaging alone.

Product name and variant

Check that the name, size, colour or other variant on the packaging matches the order confirmation. The same product name may come in several different sizes or versions.

Manufacturer and responsible operator

For product traceability, the details of the manufacturer or another responsible operator are essential. If the packaging shows no identifiable company or product identifier, it is harder to trace the origin of the product in a complaint situation.

Batch and product identifiers

EAN/GTIN, SKU, batch number and the manufacturer's model code serve different purposes. A GTIN identifies a commercial product internationally, a SKU is usually the seller's or manufacturer's own stock identifier, and a batch number helps trace a specific production batch.

More about identifiers: EAN, SKU and product codes.

Ingredient list

In cosmetic-type products, the ingredient list is given using INCI names. A long list does not automatically mean a bad product, and a short list does not automatically mean a good one. What matters is whether the list includes ingredients you want to avoid.

PAO and expiry date

The open jar symbol, for example 12M, indicates the period of use after opening stated by the manufacturer. It is not the same thing as an expiry date printed on the calendar.

It is worth noting the opening date on the packaging if the product is used over a long period.

Textile products

EU textile labelling rules require the fibre composition to be stated. For a product made of several fibres, the fibres and their percentages are stated by weight. Size, country of origin and care instructions, on the other hand, are not part of the mandatory fibre labelling under the same EU rule, even though they are useful additional information for the consumer.

Language of the instructions

In international products, the printed instructions on the packaging may be in another language. An online store should state this if the understandable use of the product depends on the written instructions.

When to complain about a labelling error

If the product information on the packaging differs substantially from the product page, for example the quantity, variant or material information is different, document both. Take a photo of the packaging and keep the order confirmation.

Quick checklist

Before use, check at least:

• the correct product and variant
• the manufacturer
• the material or ingredients
• the date/PAO, if applicable
• warnings
• storage instructions
• any batch or product identifier.

What information an online store should show before the order

A good product page should give the customer at least the information needed to identify and assess the product without opening the packaging. In practice, this means the exact name of the product, the variant, the manufacturer or brand, the quantity or size, the material or composition, and any warnings relevant to the product category.

If the product falls under cosmetics regulation, the ingredient list is essential. If it is a textile, the fibre composition is key. For a product containing electronics, the manufacturer's information on the power source, charging method and water resistance, for example, becomes important.

Example: three similar-looking packages, three different decisions

Imagine three 100 ml bottles. The first has a clear INCI list, a PAO marking and manufacturer details. The second has only a marketing name and a scent description. The third has the same information as the first, but the size on the product page differs from the packaging.

The first is easy to assess. In the second, information is missing. In the third, a discrepancy arises that is worth documenting and checking with the seller. This is a much more useful way to read a package than judging a product by its appearance alone.

Textile fibres must be stated precisely

Under EU textile labelling rules, the fibre composition of textile products is stated using fibre names and percentages. If a product contains several fibres, their proportions are not optional extra information but an essential part of the product's labelling.

This helps assess, for example, elasticity, washing and the feel of the material. It is also good to understand that care instructions are not covered by the same EU rule on fibre composition, even though in practice they are very important instructions for use.

GTIN, SKU and batch number are not the same thing

According to GS1, a GTIN is a globally unique product code. It helps distinguish commercial products and variants from one another. A SKU, in turn, is a company's own stock identifier. A batch number relates to a specific production batch.

If, for example, the same product is sold in 50 ml and 100 ml sizes, each should have its own product identifier. If the online store's image, name and GTIN do not match, it may be an error in the product data.

When to keep the instructions for use

Keep the instructions at least when the product has:

• electronic parts
• several modes of use or cleaning
• replaceable parts
• specific storage limits
• safety warnings
• terms relevant to the warranty.

Paper instructions can be photographed with a phone if that makes them easier to keep. The most important thing is that the instructions can be found later when needed.

When the online store's and the packaging's information differ

Do not resolve a discrepancy by guessing. Save:

1. a screenshot of the product page
2. a photo of the packaging label
3. the order confirmation
4. any SKU/GTIN
5. the seller's reply.

This forms clear documentation if the issue concerns a wrong product or incomplete product information.

The purpose of packaging labels is to make the product traceable

The manufacturer's name, batch number, EAN, date and warnings are not isolated details. Together they help identify the product, the production batch and the correct instructions for use.

If the information on the product page differs from the packaging, it is worth clarifying before use.

The batch number is especially important in recalls

A manufacturer may limit a safety notice to a specific batch. If the batch code appears only on the packaging, take a photo of it before discarding the outer packaging.

A batch number is not the same thing as an EAN or SKU.

An EAN identifies a version of a commercial product

A GTIN/EAN helps distinguish, for example, different package sizes or variants. The same EAN should not be used for two different commercial products if the GTIN rules require a separate identifier for them.

For the consumer, the EAN is useful for comparison between different stores.

The PAO symbol starts from opening

The open jar symbol, such as 12M, indicates the period stated by the manufacturer after the package is opened. Note the opening date if the product is used over a long period.

PAO and expiry date are different pieces of information, so check both if they appear on the packaging.

Warning labels must be read before first use

A warning may concern storage, a specific material, temperature or another restriction on use. Do not wait for a problem before reading the instructions for use.

If the instructions are multilingual, make sure you understand the instructions for the correct version of the product.

The CE marking does not automatically apply to every product

CE relates to certain product categories covered by EU legislation. Its absence is not a defect in a product to which the CE requirement does not apply, and CE alone does not prove the quality of the whole product.

Assess the marking on the basis of the product type and the applicable regulation.

The INCI list in cosmetics is standardised ingredient information

The ingredient list helps identify the composition of the product. If the online store's list and the packaging's list differ, it is important to check the up-to-date information with the manufacturer.

The composition may change over time even if the product name stays the same.

It is worth keeping the instructions for use in electronic form

If the paper instructions are small or easily lost, take a photo of them or save the manufacturer's PDF. This makes later cleaning, storage and identification of spare parts easier.

However, make sure the PDF matches your own model number exactly.

The language of the packaging and the language of the product page may differ

An international product may come in multilingual packaging. Important safety and usage instructions should be available to the consumer in an understandable form in accordance with the applicable requirements.

If essential instructions are missing in an understandable language, ask the seller before use.

Checking packaging labels takes a minute

Check the product name, manufacturer, variant, batch, date, materials/ingredients and warnings. This way you make sure you received the product you ordered.

This is a more effective routine than trying to remember all the details later.

Discrepancies in labelling should be dealt with before the product is taken into use

If the material, size or ingredient list on the product page differs from the packaging, stop before use and find out which information is up to date. The manufacturer's model number, EAN and batch code help identify the correct version.

The online store should also correct the conflicting product information so that the same ambiguity does not recur for other customers.

The version number of the instructions can be important for a technical product

A manufacturer may update the instructions without the product name changing. If the PDF instructions show a version or date, make sure it matches your own model.

Outdated instructions may contain different charging, cleaning or maintenance information from the current product version.

A symbol should always be interpreted in the context of the product category

A symbol on the packaging does not always mean the same thing in all product categories. For this reason, a marking should not be interpreted in isolation from the instructions for use or the manufacturer's website. For example, a recycling mark may indicate the material, the collection system or the sorting of the packaging, whereas a symbol related to use may refer to separate instructions from the manufacturer.

If a symbol is unclear, the safest way is to look for its explanation in the product documentation. A guess based on the image may lead to the wrong way of using, cleaning or disposing of the product. A good online store also explains the key symbols in text so that the information does not rely on an icon alone.

The language and version of the instructions should be checked

On multilingual packaging, not all instructions always fit on the product itself. Some of the information may be in a separate leaflet or behind a QR code. It is important to make sure that the instructions correspond to the exact model and version in question. Very similar-looking products from the same manufacturer may have different cleaning, charging or storage instructions.

If the instructions are downloaded from the internet, it is worth checking the file name, model number and any publication date. This helps avoid a situation in which instructions for an older version are applied to a newer product.

Batch number and model number serve different purposes

A model number usually identifies the product type, whereas a batch number or production batch code helps trace a specific production batch. Both can be useful in a complaint or when checking manufacturer notices. However, they should not be confused with the EAN code or the online store's own SKU.

Once the packaging is opened, it is worth keeping the key identifiers at least as long as the product's return or warranty period is still current. A photo of the identification details on the packaging can be a practical solution if you do not want to keep the packaging itself for long.

A warning label is not marketing text

Warnings, restrictions on use and storage instructions are product information that should be read before use. They should not be skipped because the product seems familiar or similar to a model used previously. A manufacturer may change the material, construction or technical features even within the same product family.

A good practice is to read, at the first use, at least the warnings, the cleaning instructions, the storage instructions and any information related to charging or batteries. This way the labels on the packaging become practical instructions rather than just small text on the side of the box.

Digital instructions for use should be saved in your own archive

If the instructions are available only on a website or via a QR code, it is worth saving your own copy when the product is taken into use. The address or file structure of the manufacturer's site may change over the years, but the original instructions may still be useful later for cleaning, storage, troubleshooting or a complaint.

The model name and purchase date can be added to the saved file so that instructions for different products do not get mixed up. This is especially useful if there are several models from the same manufacturer at home.

Packaging labels should be photographed before the packaging is discarded

It does not make sense to keep every package for a long time, but important identification details can be documented with a photo. The model number, batch number, manufacturer's contact details, recycling marks and any warnings are then available later without keeping the whole box.

The photo should be sharp enough that even small numbers are legible. This way the usefulness of the packaging labels remains even after the packaging itself has been sorted for recycling.

Dates and periods of use should be distinguished from each other

Packaging may show a production date, a best-before date, an expiry date or a PAO marking relating to shelf life once opened. These mean different things and should not be interpreted as synonyms. If the meaning of a marking is unclear, the manufacturer's instructions are a better source than an assumption. Especially with liquid products, noting the opening date in your own records makes later assessment easier.

Products containing batteries or other technical parts may also carry production or serial number information that has nothing to do with the period of use. For this reason, each number should be interpreted in the context of its heading or symbol.

A small product information card of your own makes long-term use easier

If a product is used for a long time, the most important information can be saved in one place: the model number, purchase date, link to the instructions, cleaning instructions and any batch number. This is not necessary for every product, but it helps when the original packaging has already been disposed of.

The information card can be a simple note on a phone. Its purpose is not to collect extra information but to preserve the facts that may be needed later for maintenance, spare parts or a complaint. This way the most important information in the instructions does not disappear with the packaging.

Unclear labelling should be resolved before use

If a symbol, warning or number on the packaging is not explained in the instructions for use, it is worth checking with the manufacturer's official source or the seller. There is no need to interpret an unclear marking yourself. This is especially important when the same packaging has been made for several market areas and there is little text. It is worth saving the explanation together with the instructions so that the same matter does not need to be clarified again later.

The instructions should also be checked after a long break

If the product has not been used for months, it is worth glancing at the key points of the instructions again before taking it into use. This way any cleaning, storage or charging instructions are not left to an old recollection.

Keeping the instructions makes later checking easier

A single saved set of instructions for use can save time years later, as the detail does not need to be searched for again.
