Cosmetic Label Requirements: A US, UK and EU Checklist Using AI

Use AI as a checklist runner: paste your label copy, name the market, and have it mark each mandatory element as present, missing or unclear. The core elements are product identity, quantity, ingredients, company name and address, warnings, batch or date information and, for UK and EU sales, a responsible person. A person must verify anything AI cannot see.

The split matters. AI reads text well and will find a missing batch code or an ingredient list that says "Perfume" where your market wants another term. It cannot know that your formula holds 4 percent niacinamide and 3 percent glycerin, so it cannot tell you whether those two are in the right order. This checklist keeps the two jobs apart, region by region, with a manual list at the end.

Cosmetic or drug: decide this before reading any checklist

Every checklist below assumes your product is a cosmetic, meaning it cleanses, beautifies or changes appearance. Claims can move it into another category. In the US, FDA's labelling summary notes that products which are both cosmetics and drugs must identify the drug ingredients first as "active ingredient(s)". A sunscreen, an anti-dandruff shampoo or a spot treatment that says it treats acne are typical examples. Those carry drug labelling rules that this tutorial does not cover.

The test is the words on the pack and the website, not what is in the bottle. "Moisturises dry skin" is a cosmetic claim. "Heals eczema" is not. Before you run any label through AI, read your claims, and if any claim sounds like treating a condition, stop and take that product to a regulatory adviser. What AI copy must not say about skincare claims goes through the wording in detail.

What the label must carry in each market

The table compares the elements side by side. Treat it as a map for the AI run and for your own checking, not as legal advice: rules differ for small packs, professional-only products and special categories, and they get amended.

Two cells say "check", and that is deliberate. The US fragrance allergen line depends on FDA finishing a rulemaking the law requires of it, and the GB allergen list can drift from the EU's now that the two systems are separate. A table that filled every cell with confidence would be inventing certainty. Confirm each row for your product against FDA's labelling pages, GOV.UK and the current consolidated EU regulation before print.

US label items, one at a time

Under FDA's summary, the front panel carries the product name, what it is or does, and the net quantity. The net quantity sits in the bottom area of the panel, in US units: pounds and ounces for solids and semisolids, fluid ounces, pints, quarts and gallons for liquids, with metric units optional. Once the quantity is a pound or a pint or more, it is stated in ounces with the larger units in brackets.

The information panel carries the name and place of business of the firm marketing the product, with street address, city, state and ZIP code. The street may be dropped if the firm is listed in a current directory. If the marketer is not the manufacturer or packer, add a phrase such as "Distributed by". Ingredients go in descending order of predominance, with colour additives and anything at 1 percent or less allowed in any order. They must be in English, with letters at least 1/16 inch tall, or 1/32 inch where the package surface is under 12 square inches.

For imports, the English name of the country of origin goes on the label. A cosmetic that may be hazardous when misused needs warnings and directions. FDA's summary also notes the statement "Warning--The safety of this product has not been determined" for products without adequate safety substantiation, which is a red flag you should never need. MoCRA added a labelling section, section 609, to the FD&C Act: since 29 December 2024, every cosmetic label must carry a domestic address, domestic phone number or electronic contact, which may be a website, through which the responsible person can receive adverse event reports. The same section requires a product meant only for licensed professionals (in cosmetology, nail care, barbering or esthetics) to say clearly and prominently that only licensed professionals may use it.

UK and EU label items, and the responsible person

For Great Britain, GOV.UK lists what the container and packaging must show: the responsible person's name and address, country of origin for imports, weight or volume, use-by date, precautions, a batch or identification number, what the product does and the ingredients. The ingredients may sit on the outer packaging alone. If space prevents precautions or ingredients appearing on the pack, the guidance allows them in an enclosed leaflet (the regulation also allows a label, tape, tag or card) with a symbol pointing to it. GOV.UK says the weight or volume and the use-by date may not be needed where contents are under 5 grams or 5 millilitres.

The responsible person is the legal owner of compliance. GOV.UK describes it as the manufacturer, the importer, a distributor selling under its own brand, or a person or company the manufacturer or importer appoints. It can be a sole trader. It must have a UK established address; a mail-forwarding or PO box address does not count. GOV.UK's guidance covers Great Britain; for Northern Ireland it says the responsible person must be established there or in the EU. The EU works the same way: the responsible person must be established in the EU, appointed by written mandate if it is not the maker or importer. A business selling into both markets therefore needs a responsible person in each.

The label line has a wrinkle. The GB version of Article 19 contains a transitional clause, running for seven years from the start of 2021, so to the end of 2027, under which a label that meets the EU name-and-address rule also meets the GB one. A label carrying only your EU responsible person's details can therefore still satisfy GB for now, though the GB responsible person must still exist and file the notification. Put the artwork change for 2028 on your calendar, and check legislation.gov.uk for any extension before relying on the clause.

Article 19 of the EU regulation lists the same family of items: responsible person, country of origin, nominal content, date of minimum durability or the period-after-opening symbol, precautions, batch number, function and the ingredients list headed "Ingredients". The date rule runs on a 30-month line: a product that will last longer than 30 months does not need a date but needs the open-jar symbol and a number of months. Where a date is used, it is month and year (or day, month and year) after the regulation's symbol or the words "best used before the end of". Perfume and aroma compositions are declared as "parfum" or "aroma", colourants by their colour index numbers after the other ingredients, and ingredients under 1 percent can be listed in any order after those above 1 percent.

Both systems require a notification before sale, filed by the responsible person: GOV.UK's Submit cosmetic product notifications service, and an electronic notification to the European Commission. That is not a label item, but the EU filing includes the original labelling and, where legible, a photograph of the packaging, so a late artwork change means updating a filing.

The EU fragrance allergen update

The EU extended the list of fragrance allergens that must be named on the label through Regulation (EU) 2023/1545. The European Commission's page on the change says it adds individual labelling for 56 more allergens. Products that do not meet it may no longer be placed on the EU market from 31 July 2026, and products placed on the market before that date may stay on sale only until 31 July 2028. Summaries quote different counts because some annex entries group several related substances, so check your fragrance against the annex itself rather than a number. The thresholds are 0.001 percent in leave-on products and 0.01 percent in rinse-off products.

The practical effect: a new leave-on product placed in the EU now may need newly listed names such as Vanillin, Menthol or Camphor after "Parfum" in the ingredients list, because a fragrance blend contains them above the threshold. You cannot tell from the label. Ask your fragrance supplier for the allergen declaration for the exact blend and batch, and compare it with the printed list.

A worked run: three products, three markets

An illustration. A small skincare brand sells a 30 ml face serum, a 15 g lip balm and a 250 ml body wash, wants to ship all three to US, UK and EU customers, and uses one shared artwork template. The owner pastes each label's text, region by region, into a chat with the prompt below. A realistic first run takes about 20 minutes for all nine combinations (three products, three markets) because the prompt is reused.

You are a label checklist runner, not an approver. I will paste the
exact text printed on a cosmetic label. Market: [US / UK / EU].
Product type: [leave-on / rinse-off], pack size: [30 ml].

Using only the checklist below, produce a table: element | text found
(quote it, or "none") | verdict (PRESENT / MISSING / UNCLEAR) | what a
human must verify. Do not say the label is compliant. Do not guess
ingredient order or percentages. If a rule depends on pack size, say so.

CHECKLIST (US): name and what it is; net quantity (US units, bottom
area of front panel); name and place of business, with "Distributed by"
if not the maker; ingredients in descending order, English; warnings
and directions where relevant; US contact for adverse events.
CHECKLIST (UK/EU): function; nominal content; responsible person name
and market address; country of origin if imported; precautions;
batch number; use-by date or open-jar symbol with months; ingredients
headed "Ingredients"; fragrance allergens named where required;
(nano) marked where present.

LABEL TEXT:
[paste]

Illustrative output for the serum in the EU (shortened):

Function | "Brightening face serum" | PRESENT | check "brightening" claim evidence
Nominal content | "30 ml" | PRESENT | check units and size on print proof
Responsible person | "Made by [brand], [street], [city]" | UNCLEAR |
   address appears to be outside the EU; confirm the EU responsible
   person's name and address are on the pack
Batch number | none | MISSING | add a batch code area
Durability | "PAO 12M" symbol described | PRESENT | confirm symbol is the
   open-jar graphic, not just text
Ingredients | "Aqua, Glycerin, Niacinamide, Parfum..." | PRESENT |
   verify order against formula; verify allergens against fragrance
   supplier declaration
Allergens | "Parfum" only | UNCLEAR | confirm whether named allergens
   exceed 0.001 percent in this leave-on product

Notice what the output does not say. It does not say the serum passes. It found two gaps it can see (no batch code, a probable missing EU responsible person) and three things it must hand to a human. The brand fixes the first two on the artwork, and the three hand-offs go onto the manual list. Run the same prompt for the lip balm, where the 15 g pot gets no small-pack relief (a sample under 5 g would), and for the body wash, where the allergen threshold is the higher rinse-off one and the 250 ml bottle has plenty of room.

The manual verification list: what AI cannot sign

These are checks a person does with documents, not with a chat window. Each line says where the answer lives.

1. Ingredient order against the formula. Take the formula sheet from your manufacturer, sort descending by percentage, and compare line by line with the printed list. In the EU and UK, ingredients below 1 percent may follow in any order after the rest; in the US, ingredients at 1 percent or less and colour additives may go in any order. Check the one-percent boundary ingredient by ingredient.
2. INCI names. Each ingredient must appear under its INCI name or the legal equivalent in the market. Do not trust a supplier's trade name. See checking an INCI list with AI for the name-checking routine; it is a naming check, not a safety sign-off.
3. Fragrance allergen declaration. Written supplier statement for the exact fragrance, matched against thresholds and the current list for the market.
4. Responsible person agreement. A written appointment, the address you print, and a named contact who can answer a regulator. Check the address is real and not a forwarding service.
5. Notification filed. UK and EU notifications submitted before the first sale, with the label images matching the artwork you print.
6. Safety assessment on file. A qualified assessor's report exists for each formula. Can AI write a cosmetic safety report explains why that signature is a person's.
7. Claims evidence. A file for every claim on pack. "Dermatologically tested" and "vegan" need paperwork behind them.
8. Print proof size. Measure the printed lettering and the quantity statement on the proof, not the PDF on screen. US ingredient lettering has a minimum height; AI cannot measure it from text.
9. Date and batch coding. The coding on the real bottle is legible, permanent and matches the batch record.
10. US contact and company line. The address, phone or electronic contact for adverse event reports is correct and monitored.

Keep this list as a signed one-pager per product with a date and the checker's name. Treat the AI table as the first draft of that document, not a substitute for it.

A mistake that passes the AI check and fails in the real world

Here is the kind of error AI will not catch. An illustrative maker reformulates a serum, raising glycerin from 3 percent to 5 percent, and reduces niacinamide to 2 percent. The ingredient list on the artwork is never updated, because the text is copied from the old file. AI runs the checklist, finds an ingredient list present, headed correctly, in English, and marks it PRESENT. The label is wrong: glycerin should now come before niacinamide.

The fix is process, not a better prompt. Make the formula sheet the source of truth, regenerate the ingredient list from it every time the formula changes, and add a line to the change record: "label ingredients re-checked against formula version [number]". A second prompt does help here when you paste the formula sheet in as well: "Sort these ingredients by percentage and compare with the printed list; flag differences." That works because you gave it the data it was missing. A formula sheet is confidential, so use an AI plan with business data protections and strip anything you do not need to share, such as supplier names.

Smaller details that keep catching new brands

Pack size, multipacks and gift sets

A gift set of three products needs the information for each item on the item, plus the outer box information. If the outer box hides the inner labels, the outer must carry the full mandatory set. Ask the AI to run the checklist twice, once for the inner container and once for the box, and list what repeats.

Imports and repackaging

A US brand that sells into the UK has to name a UK responsible person, and their address replaces or sits beside the brand's own. A UK brand selling into the EU needs the EU equivalent. Where a distributor repackages, the distributor may take on the responsible person role, and with it the duty to hold the safety file. The label should say who that is, and that person should know.

Languages and units

US ingredient declarations must be in English, and the net quantity is given in US units with metric optional. The EU leaves the language of some mandatory items to each member state, so a label for several EU countries may need several languages for precautions and function. For Great Britain, the Cosmetic Products Enforcement Regulations require the content, durability, precautions and function information in English, whether or not other languages appear as well. Ask AI to translate a precaution only as a draft, and have a speaker of that language approve it, since a mistranslated warning is a bigger problem than a missing one.

Sample sizes and testers

Under 5 g or 5 ml, some UK items are relaxed. The relief is narrow: it does not drop the responsible person or the ingredients, which can move to packaging or a leaflet with a symbol. A tester or sample in a shop is still a product placed on the market.

How to run the checklist each time you change something

Build the habit around change, because labels go wrong when a small edit sneaks in. Run the checklist whenever one of these happens: a formula changes, a fragrance supplier changes, a pack size changes, a new market is added, a new claim appears on pack or website, or a regulator's update lands (the EU allergen change is the live example). Keep a one-line log per product: date, trigger, who checked, which version of the artwork.

1. Export the final label text from the artwork file, not from a screenshot, so it matches what prints.
2. Paste the text and the market into the prompt above.
3. Read the table, fix PRESENT/MISSING items on the artwork.
4. Work through the manual list for anything marked UNCLEAR or changed.
5. Have a second person read the printed proof against the table.
6. Save the table, the proof and the sign-off together, and file the notification update if the label changed.

The review step is the same pattern as any AI work that reaches customers; setting up human review for AI work shows how to keep it from slowing everything down. If you have several products, put the checklist prompt in a shared place, which a shared prompt library for your team covers.

What to check before you trust the result

Test the process on a label you know is flawed. Take an old pack, delete the batch code, swap two ingredients and remove the company address, then run the prompt. If the AI does not flag the missing batch code and address, tighten the prompt: make it quote the text it found and say "none" when nothing matches. If it flags the swapped ingredients without having the formula, it is guessing, which is a sign to stop trusting that output. Run the test once a quarter, since models and your own prompt drift.

The most useful single rule: never accept a PRESENT verdict without the quoted text beside it. A verdict with no quote is a claim with no source. If a regulator, retailer or marketplace asks about a label, your answer is the signed manual list and the notification, not a chat transcript. If you would like help turning this into a routine for your range, that is what my AI implementation consultation covers, though the sign-off on a specific label belongs to a regulatory adviser who knows your markets.

Label questions skincare makers ask

Can AI approve my cosmetic label as compliant?

No. It can compare your label text against a checklist and flag missing or unclear items, which saves time. It cannot see your formula percentages, your safety report, your claims evidence or the printed artwork size, and the regulations change. A person responsible for the product signs off.

Do I need a responsible person for UK and EU sales?

Yes, each market needs a named responsible person established inside that market, and a responsible person's name and address go on the label (until the end of 2027, the GB rules also accept the EU person's details on the label). GOV.UK says a UK address cannot be a mail forwarding or PO box address. Your supplier, importer or an appointed service can hold the role, in writing.

Do the UK and EU label rules match?

They are close in structure, because the UK kept the same core regulation, but they are now separate systems with separate responsible persons, notification portals and updates. A change in one, such as the EU's expanded fragrance allergen list, does not automatically apply in the other. Check both for each product.

How do I list ingredients when a fragrance is a blend?

Declare the blend as a fragrance term in the allowed form for the market, and in the EU and UK also name any listed fragrance allergens present above the leave-on or rinse-off thresholds. Get the allergen declaration from your fragrance supplier in writing, not from AI.

What if my product is too small to fit everything?

Small packs have partial relief in some markets, such as a leaflet or tag with a symbol pointing to it, and a lower size limit for some items. Check the exact exemption for your market and pack size, then ask AI to list what must stay on the container itself.
