CLP & GHS Labelling for Cosmetic OEM Shipments

Classification sits upstream of artwork in a way that is easy to miss, because the two documents look unrelated. A hazard classification decides whether a pictogram, a signal word & a set of statements go on the pack at all; the presence of those elements changes the size of the label panel, the amount of text that has to be laid out around them, the print method, & in some cases whether the primary pack can stay the size the brand wanted. A hundred millilitre bottle designed without a pictogram in mind will not accommodate one afterwards, & a label that has to be reprinted because a classification was revised after print is a cost nobody budgeted.

This note sets out where hazard classification applies to a cosmetic shipment & where it does not, how the European CLP regulation & the United Nations GHS framework relate to each other, which hazard classes appear most often in this sector, how pictograms & signal words are selected rather than chosen, how precautionary statements differ from hazard statements, what the boundary looks like between this regime & the cosmetic rules, who compiles a safety data sheet & what the sixteen sections hold, where such a sheet is actually wanted & where asking for one is wasted effort, how supply labelling differs from transport labelling, which fields must match between documents, & what happens when the formula is revised. Nothing here is a statement that any product or any classification is correct for a given market; that determination belongs to whoever holds responsibility for the product in that market, against the current texts.

Why classification happens before the artwork does

The sequence problem is structural. Classification is derived from the composition & from test data or accepted calculation methods applied to that composition. Once derived, it dictates elements that occupy physical space on a surface whose dimensions were already chosen. Working the other way round — designing the pack, printing it, then discovering that two pictograms & six statements must appear — leaves three bad options: print an overlabel, accept a smaller format, or re-design.

The classification also does not belong to the artwork team. It belongs to whoever holds the compositional knowledge & the toxicological input, which in most OEM arrangements means the factory supplies the composition & the raw material data, & the responsible person for the market uses it to derive the position. A brand that asks the factory to "just put the right pictograms on" has moved that derivation to someone who does not hold the destination-market responsibility for it.

Time is the practical constraint underneath all this. Composing the hazard & precautionary statements, translating them into every required language, laying them out legibly at the mandated minimum sizes, & having them checked is a sequence of weeks for a multi-market launch. Compression at the end of that sequence is what produces the errors that are found on a pallet rather than on a screen.

Hazard classes that appear in cosmetic work

The classification system sorts hazards into physical, health & environmental classes, & cosmetic work touches each of them in predictable places. Physical hazards dominate for anything with alcohol: a product above a certain ethanol content & flash point is a flammable liquid, & that single finding dictates more label content than any other finding in this sector. It applies most obviously to a fragrance, a hair spray, a setting mist, an aftershave & some toners.

Aerosols are their own category rather than a flammable liquid, & a pressurised container carries specific hazard statements about pressure & heat regardless of what is inside it, with the flammability of the propellant adding further statements. Where a brand moves from a pump to an aerosol for the same formula, the label content changes substantially even though nothing about the liquid did.

Health hazards in this sector most often concern irritation or sensitisation. A product classified for serious eye irritation or skin irritation takes the corresponding pictogram & statements; one classified as a skin sensitiser does, & this is the classification a fragrance-heavy product most often attracts through its components rather than through anything the formulator added deliberately. There are also accumulation-based approaches for mixtures where data are limited, & the outcome depends entirely on the percentages & on what is known about the components.

Environmental hazards occasionally reach a cosmetic label through components such as certain silicones, certain preservatives or a UV filter, though the single most common environmental trigger is a material that is not there for cosmetic reasons at all. Cleaning agents used in the plant are not relevant to the label, obviously, & neither is the fact that a component is persistent in the abstract; what matters is a formal classification with the specific criteria attached, & that is a determination rather than an impression.

Pictograms, signal words & hazard statements

A pictogram is not decoration & it is not a choice. It is a black symbol on a white background inside a red diamond, & it follows from the hazard class & category that the classification produced. Flammable, irritant, corrosive, health hazard, environmental hazard, compressed gas & oxidising each have their own symbol. Where several apply, the set is placed together rather than selected down to the most alarming one.

The signal word works the same way: it is either "Danger" or "Warning", decided by the severity band reached rather than by preference. Some categories attract no signal word at all. The choice is made by the classification result & not by the person laying out the label, which is why the classification has to be recorded as a document before artwork begins.

Hazard statements are coded phrases such as H225, H315, H317 or H319 in their European form. They describe the nature of the hazard in standardised language, they carry no instruction, & they must be reproduced accurately in every required language. Misquoting the wording while keeping the code is a common & consequential error, because the code is what is checked against the list & the wording is what a reader actually sees.

There is also an arrangement most people learn the hard way: certain combinations are redundant & should be suppressed. Where both a general & a specific statement could apply, the framework generally directs that the narrower one is used, & where a product carries one hazard statement another becomes unnecessary. Getting this right is a technical read rather than a matter of taste, & it should be done by whoever derived the classification.

Precautionary statements & where they sit

Precautionary statements are coded P phrases, & they exist to describe recommended measures: prevention, response, storage & disposal. They are selected from a defined table per hazard class & category, & some are mandatory in specified circumstances. This is where a large part of the label volume comes from, & it is why a classified product needs a larger panel than an unclassified one.

Placement follows rules of its own. A set number of precautionary statements normally appears on the label rather than being pushed into a leaflet, & where space genuinely does not allow, derogations exist for small packs with specified limits on dimension. Those derogations are narrow, they differ between pack sizes, & they are not a general licence to move text off the panel. Deciding to ship in a travel size without checking the small-pack rules is a frequent way to inherit a problem.

Then comes the interaction with the cosmetic information that also has to be present. A cosmetic label already carries an ingredient list, a nominal content, a responsible person address, a batch code, a durability indication & possibly warnings & instructions for use. The hazard & precautionary content joins that set rather than replacing any of it, so the total panel requirement is the sum of two regimes. Where those texts end up in different languages or in different formats on the same label, the result is usually a reprint.

The final practical point is the combination deadline. Where several hazards attract several statements, some combinations are explicitly disallowed or are to be preferred over others. A label carrying contradictory instructions — keep away from heat alongside no particular storage caution, or two conflicting disposal routes — is a symptom that nobody checked the set as a set.

The exemption boundary & the cosmetic rules

Cosmetic products placed on the European Union market are within the scope of CLP for classification & labelling purposes, with specific provisions affecting how certain elements appear. The relationship has been revisited over successive updates, so the boundary is not a fixed line that can be memorised once. What can be said generally is that the two regimes do not cancel each other out: a cosmetic product may carry both a cosmetic ingredient declaration & hazard communication, & where the cosmetic rules prescribe a warning in specific wording, that requirement is additional rather than substitutable.

The practical consequence for a buyer is that there are two answers to two questions. The first is whether this product, as a mixture, meets the classification criteria; the second is what has to appear on the pack under the cosmetic rules. Both have to be answered for the same unit, they are answered from different texts, & they are answered by different functions. Collapsing them into one question is the origin of most confusion in this area.

Transport & supply are then a third & fourth answer, described below, which is why large organisations separate these into named responsible individuals. In a small brand they are usually one person working through four checklists, which works provided the separation is understood.

Finally, the geographical scope matters more than it appears. Great Britain maintains its own version of the classification & labelling rules after the end of the transition period; the European Union maintains CLP; the United States has a different framework again, as do Canada, Japan, Korea, China, Australia, the ASEAN bloc & most others, many of which are based on the same United Nations model while differing in which building blocks & thresholds they adopt. A single global artwork file is rarely achievable without variation.

Safety data sheet: the sections & who compiles them

A safety data sheet is a sixteen-section document, & the section structure itself is standardised. Sections one through three cover identification, hazard identification & composition: product identifier, other means of identification, recommended use & supplier details, the classification & label elements, & the composition with each component identified to the extent required. Sections four through six cover first aid measures, firefighting measures & accidental release measures. Section seven covers handling & storage, section eight exposure controls & personal protection.

Sections nine to eleven are the physical & toxicological core: physical & chemical properties, stability & reactivity, & toxicological information. Sections twelve to fifteen cover ecological information, disposal considerations, transport information & regulatory information. Section sixteen covers other information, including the version history. That structure is the reason the document is long & why it is rarely read in full; most readers go to sections one, two, three, nine, fourteen & fifteen.

Who compiles it depends on who holds the composition & the data behind it. For a raw material, it comes from the raw material supplier & must be dated, in the language required by the destination, & in the current format. For a finished mixture, it comes from whoever classifies that mixture & places it on the market — in a cosmetic context, that is normally the responsible person for the market in question rather than the factory that filled it. The distinction matters because it decides who has to maintain it & who has to sign it.

The version & language fields are where practical failures concentrate. A sheet three years old may have been superseded; a sheet in English only may not be acceptable in a market where another language is required; a sheet whose revision date precedes a change in the formula is describing a product that no longer exists. Each of those is trivial to check & each is frequently not checked.

Where a safety data sheet is wanted & where it is not

A finished cosmetic supplied to a consumer generally has no safety data sheet obligation, since the obligation attaches to substances & mixtures supplied for use at work or certain other circumstances rather than to a retail unit handed to a customer. Asking a factory for a sheet for a retail cream is therefore usually asking for something the framework does not require, & receiving one usually means receiving either a raw material set or a document produced as a courtesy.

What is genuinely needed is different. For each raw material, the manufacturer's current sheet supports the factory's own hazardous substance inventory, its storage segregation, its worker training & its emergency response. For a bulk shipment moving between two businesses — factory to brand, brand to a third-party filler, factory to a distributor — the receiving party may need transport documentation & may need compositional data to perform its own duties. Those are legitimate requests & should be made as such rather than bundled into a vague "send the SDS".

Where a product is classified, the situation changes. A classified mixture supplied onward triggers its own communication obligations, & the sheet is part of how those are met. An alcohol-based product sold through professional channels — salon, spa, clinic — is the case where this most often bites, because professional use is a workplace use & the expectations attach accordingly.

For international movement there is a further layer: a shipment may need documentation to satisfy a customs authority or a carrier regardless of the hazard classification. The broader picture of what travels with a consignment sits in our note on export documentation & shipping requirements, & the ingredient-facing part of the same problem — what each component is called & how it must be named — is set out in our guide to ingredient naming across markets.

Supply labels versus transport labels

Supply labelling & transport labelling are two systems with two histories, & they frequently end up on the same carton. Supply labelling is the CLP or equivalent label: pictogram, signal word, hazard & precautionary statements, product identifiers. Transport labelling carries the diamond placards, the UN number, the proper shipping name, the packing group where applicable & handling marks such as orientation arrows or fragile markings.

The mistakes here are predictable. A carton printed with a supply pictogram because someone thought it looked appropriate. A pallet without the required placard because the print space was used for a bar code. A limited quantity shipment that the sender did not know qualified for simplified arrangements, & therefore packed & documented at greater expense than necessary. A shipment that did not qualify but was handled as though it did.

The classification for transport is separate from the classification for supply, even though both start from the same composition. Certain hazard classes are handled differently, some are out of scope for one mode & not another, & air, sea, road & rail each have their own governing text with the same parent model behind them. A consignment moving by sea & then by road crosses two sets.

There is also an obvious but overlooked consequence for e-commerce. A parcel handed to a courier by a retail warehouse enters a transport chain with expectations attached, & those expectations do not disappear because the parcel came from a retailer rather than a manufacturer. Returns flows carry a further complication, because a customer returning a classified product is undertaking a transport activity they have no reason to know about.

Language, field size & legibility on pack

Language is a hard requirement rather than a courtesy: in most markets the label information must appear in the language or languages prescribed by that market, & it must be legible & indelible. For a multi-market launch this multiplies the panel content, since the same statements have to be reproduced in each required language on the same surface. Where the required set will not fit, the practical answers are a larger label, a folded leaflet where permitted, or a market-specific artwork variant — & each of those changes the unit cost & the print minimum.

Minimum font sizes interact with this. The European rules set minimum type sizes scaled to pack capacity; other markets set their own; & the effect of a prescribed minimum is that a statement set that fits aesthetically may not fit legally. Checking the text set against the smallest unit in the range, rather than against the hero size, is the step that prevents a launch-wide reprint.

Type colour & contrast are governed too. Statements must be legible against their background, which rules out much of the pale-on-pale design language that appeals to premium skincare brands. Where a brand requires a specific aesthetic, the usual resolution is a separate panel, a separate carton face, or a secondary card rather than an attempt to integrate the statements into a design that cannot carry them.

Durability is the requirement most often skipped. Information must remain legible under normal conditions of storage & use, which for a product that lives in a wet bathroom means print that survives condensation & handling. A rub test set as a defined method rather than as an opinion is the cheap control, & it belongs in the specification rather than in a memory.

Revision control when the formula changes

Any change to the composition has the potential to change the classification, & therefore the label. This is the mechanism by which a launched & apparently settled product acquires a requirement unexpectedly: a raw material supplier reformulates a preservative blend, a fragrance house substitutes a component for availability reasons, a concentration moves within its permitted range, & the accumulation arithmetic produces a different answer than it did before.

The route for managing it is mundane but effective: a named trigger, a named reviewer, & a named record. The trigger is any notification from a supplier that a composition has changed, plus any internal change to concentrations. The reviewer whoever derived the classification. The record is a revision table showing what changed, when, what was re-derived, & whether the label set changed as a result.

What makes this difficult in practice is that supplier notifications are inconsistent in quality. Some suppliers notify everything, some notify nothing, & some notify only when asked. Building the obligation into the purchase terms — that changes must be notified in writing before shipment — is the only dependable means of receiving them.

Then there is the stock question. A classification change affects goods in the warehouse, goods in transit & goods already on shelf, & those three populations may be handled differently with transition periods available for some situations. Deciding before it happens how the brand will handle each population is faster than deciding during it.

Labelling & classification fields at a glance

The table below sets the principal fields against what each controls, who usually provides the input, & the point most often missed. Read it as a description of how such files are normally assembled rather than as a statement of requirement for any particular product; the applicable rules depend on the composition, the classification derived from it, the supply route & the destination market.

The dependency again runs in one direction. The composition yields the classification; the classification yields the elements; the elements yield the space requirement; & the space requirement decides whether the pack & the artwork can proceed as designed. Working backwards from a finished design is what produces overlabels at the last moment.

What to put in the brief

A labelling brief should separate three things that are usually merged into one request: what has to appear under hazard communication rules, what has to appear under cosmetic rules, & what documentation has to travel with the goods. Each is drawn from a different source & owned by a different party, so stating them separately gets each answered by the right person.

• The destination markets, named individually rather than as a region or a bloc.
• The alcohol content & flash point where a spray, mist, toner or fragrance is involved.
• Whether the pack is a pump, an aerosol or a bag-on-valve, since each changes the result.
• The languages required on pack for each market, & whether variants will be accepted.
• The smallest & largest unit of the range, so the type size check covers both ends.
• Whether any part of the channel is professional rather than retail.
• The raw material data set required, with revision dates & languages specified.
• Who holds responsibility for the classification & for maintaining it after launch.

Then settle the change route before the first order: what counts as a change, who has to be told, what happens to stock already made, & how quickly the panel will be revised if it must be. Those four answers turn a future surprise into a scheduled task, which is the difference between a reprint & a recall discussion.

Where our capability fits

We regard classification & labelling as inputs to the artwork rather than as outputs of it. The composition is captured with identifiers & concentrations at the point a formula is frozen, the raw material data set is collected with its revision dates attached, & the physical properties that bear on classification — flash point where relevant, alcohol content, pH band, physical form & the pack type — are recorded alongside the formula version. Where the derivation belongs to the responsible person for a market rather than to us, we supply the composition & the data rather than the conclusion, because that is where the responsibility sits.

We work with brands on private label (your brand on a proven base), OEM/ODM contract manufacturing & full custom formula development, & we flag the design consequences of a classification early enough for the pack to accommodate them. The same approach runs across a cleanser filled into a tube, a lotion filled into a pump bottle & an argan hair oil programme, where the panel content, the language set & the print durability checks differ but the sequence does not.

Tell us the formula direction, the pack types you are considering & the markets you plan to sell in, & we will come back with the data we can provide, the fields your own responsible person has to derive, & the order in which we would run it.

General manufacturing information, not regulatory or legal advice. Whether a product meets the classification criteria, which elements must appear on its label, which languages apply & what documentation travels with a consignment all depend on the composition, the supply route & the destination market; the texts & their transition periods change; & the position for any specific product must be confirmed with the competent authority in the market where it will be placed.
