Four Compliance Pitfalls in Cosmetic Packaging Labels: The Real Costs of Incorrect Filing Numbers, Ingredients, Shelf Lives, and Warning Statements

Last month, a client who produces facial masks contacted me after receiving a corrective action notice from the drug regulatory authority: “The ingredient list on the packaging of this facial mask does not comply with the ordering requirements, the INCI names mix Chinese and English, and the required warning statements are missing.Please rectify the issues within 7 days; otherwise, the product will be removed from sale.」The customer's first reaction was not to take corrective action, but to ask the printing factory: “Why didn't you remind me at the time?”The printing company is also wronged—the customer never said the product would be launched on the market, only, “Print a small batch for me to try.” Who would have thought it would end up being officially distributed?

This client’s pain point is one that 90% of cosmetics packaging buyers encounter: the risk of non-compliant cosmetics labels. Both the printing supplier and the client assume the other party will manage it, so in the end, no one does. When a serious problem arises, they share the blame.This article thoroughly explains 4 major pitfalls in cosmetic packaging labels.

Minefield 1: Filing Number Font, Placement, and Contrast

The cosmetics filing number is the product’s “identity card” issued by the National Medical Products Administration. An incorrect filing number means that the product lacks “legal status” and cannot be marketed.

Three common errors in cosmetic product filing numbers:

1) Font size too small (below 1.5 mm).Regulations require the filing number to have a font height of no less than 1.5mm, but in practice, many customers print the registration number at 1mm or even smaller to make the packaging more visually appealing.The customer believes that “as long as it is visible to the naked eye, it is acceptable,” but during spot checks by the drug regulatory authority, a caliper is used to measure it, and 1 mm makes it noncompliant.

2) The position is obscured by the pattern.The registration number is printed on the bottom or side of the box, but it may be covered by gold foil patterns, UV spot varnish, embossing, or similar finishes, making some strokes of the registration number difficult to read.Regulations require the registration number to be clearly legible; if it is covered, it is treated as missing.

3) Insufficient color contrast.The filing number is printed in light gray or pale gold, making it almost invisible on light-colored boxes.Regulations specify color contrast requirements for registration numbers: dark text should appear on a light background, and light text on a dark background, so that the text does not blend into the background.

Real-world costs: A customer's facial mask registration number was printed in 1mm light gray lettering on the bottom of the box. Following a spot inspection, the company was fined 50,000 Yuan and required to recall all 8,000 boxes. Recall, shipping, and storage costs totaled approximately 120,000 Yuan.The loss from a single transaction was 170,000 Yuan, while the total cost of printing this batch of boxes was only 40,000 Yuan.

How business owners can avoid pitfalls: look at 3 key details.- Font height ≥ 1.5mm (measured with calipers) - Filing number placement: not covered by any finishing process (hot stamping, UV, and embossing must all avoid this area) - Color contrast: dark text on a light background or light text on a dark background; avoid using similar colors for the text and background

Pitfall 2: Mixing Chinese and English in the INCI ingredient list or using an incorrect order

The cosmetic ingredient list is a major challenge in label compliance.Regulatory requirements: Ingredients must be labeled using their Chinese INCI names, which are internationally standardized, and must be listed in descending order of concentration. Ingredients with concentrations below 1% may be listed in any order after all ingredients with concentrations above 1%.

Three common types of errors in the ingredients list:

1) .,"Glycerin / Glycerin / Propylene Glycol / ".INCI ; a."," +.

2) ."," ",.",,.",Glycerin,Propylene Glycol,Glycol…" —,.a ( 0.5%),≥1%.

3) INCI .,"Dipotassium Glycyrrhizinate" " Glycyrrhizinate," "Sodium Hyaluronate" "Sodium Hyaluronate " — -.INCI ; "."

Actual cost: A client mislabeled “CI 77491” (iron oxide red) as “CI 77419” on the lipstick ingredient list. This one-digit discrepancy was deemed “ingredient fraud,” resulting in a fine of 80,000 Yuan, more than 200 customer complaints, and a complete delisting from all e-commerce platforms.A loss exceeding 300,000 Yuan.

How Business Owners Can Avoid Pitfalls: Look for These 3 Details.- Chinese INCI names must be checked against the Catalogue of Cosmetic Ingredient Names, an official document issued by the National Medical Products Administration. - Ingredients must be listed in descending order of concentration. - The ingredient list provided by the customer must bear the signature of the formulator and the company seal; a verbal description is not acceptable.

Pitfall 3: Labeling the "Production Batch Number" and "Use-by Date"

Shelf-life labeling for cosmetics is another area prone to violations.Regulatory requirements: Cosmetics must be labeled with the “production batch number” and “date of minimum durability” (or “production date + shelf life”).

Three common shelf-life errors:

1)Only the production date is marked, but the shelf life is not indicated. For example, only 「Production date: 20250101」 is printed, without indicating 「Shelf life: 36 months」 or 「Use-by date: 20280101」. Regulations require both to appear together.

2) Incorrect date format for the “best before” date. The correct format is "2028/01", "20280101", or "January 2028". However, customers often write "2028.1", "2028-1", or "2028/1", and submissions are rejected because the format is not standardized.

3) The use-by date is obscured by the printing process.The same issue occurs with the filing number: when printed on the bottom or side of the box, it may be covered by hot foil stamping, UV printing, or embossing, making the date partially illegible.Customers cannot determine whether the product has expired when using it, leading to complaints.

Actual invoice: A client’s serum packaging had the use-by date printed as “2028.01」, was judged as “improperly labeled,” resulting in mandatory corrective action and a fine of 30,000 Yuan.The bigger issue is that this serum has already sold 50,000 units through e-commerce, and every unit needs an additional label. The combined labor and material costs for applying the labels amount to approximately 80,000 Yuan.

How Bosses Can Avoid Pitfalls: Look at 3 Key Details.- The production batch number and the use-by date must be indicated together, or the production date and shelf life must be indicated together. - Use-by date format: YYYY/MM or YYYYMMDD. Avoid using an open date format.Symbols such as 」 and - are nonstandard — Label placement: same as for the registration number; avoid hot-foil stamping, UV, and embossed areas.

Minefield 4: Missing or Nonstandard Warning Statements

Cosmetic warning statements are "safety reminders" required by regulations. Certain product categories, including hair coloring, perming, spot-removing and whitening products, sunscreens, and infant and child products, must bear specific warning statements.

Three common types of errors in warning statements:

1) Missing warning statement.For example, hair dyes must bear the warning, “Hair dyes may cause allergic reactions. Test on the skin for 48 hours before use.” However, many customers omit this statement to keep the packaging simple.Regulations require mandatory labeling; omitting it constitutes non-compliance.

2) The warning text placement or font size is noncompliant.Regulations require warning statements to be clear and legible, with a font size of no less than 1.5mm, and it must not be obscured by other graphics.Many customers print warning statements on areas measuring just 1mm or hide them on the bottom of the box, resulting in noncompliance.

3) The warning wording is not standardized.For example, “Do not come into contact with eyes” is improperly phrased as “Keep it out of your eyes,” and “Children must be supervised when using this product” is improperly phrased as “An adult must watch children use this product.” Improper wording means non-compliance.

Actual cost: A customer's sunscreen was missing the warning, “Children must use under the supervision of a guardian.” After being selected for inspection, the company was fined 50,000 Yuan, had its products delisted from all sales channels for 7 days, and received widespread media exposure.Loss of GMV from being delisted for 7 days ≈ 150,000 Yuan.

How Business Owners Can Avoid Pitfalls: Look for These 3 Details.- Hair dyeing / perming / spot removal and whitening / sun protection / infant and children’s products: the 5 categories must display specific warning statements - warning statement font size ≥ 1.5mm; the position must not be covered by any process. For warning text, use the standard wording recommended by the applicable regulations; do not simplify it or rewrite it in an informal style.

4 Lines of Defense for Cosmetics Label Compliance

Having covered the 4 major risk areas, let us now look at the 4 lines of defense in cosmetic label compliance.

The first checkpoint: the label information provided by the customer must be complete, including the filing number, ingredient list, shelf life, and warning statements. None may be omitted.If the customer has not provided complete artwork, the printing plant should proactively ask for clarification rather than simply printing whatever the customer says to print.

Step 2: Print Factory Internal Audit — Verify INCI Ingredient Names against the Cosmetic Ingredient Name Catalogue, ensure that shelf-life statements follow the required format, and check warning statements against the applicable regulations for each product category.Many printing plants skip this safeguard and print directly from the imposed layout; when problems arise, they shift all the blame to the customer.

Step 3: Sample Confirmation — During sampling, photograph each label field separately and submit the photos to the customer for confirmation. Have the customer provide a written response stating, “Confirmed as correct and approved for mass production.”This step can eliminate 80% of compliance issues.

Step 4: Check once more before mass production—the final proofreading before mass production. Compare the 4 fields: filing number, ingredient list, shelf life, and warning statement against the applicable regulations item by item, and start the machine only after confirming that everything is correct.

Cosmetic label compliance is not simply a matter of “having the printer print it”; it means that the printer helps the customer clear the regulatory hurdles. Customers cannot be expected to understand every regulation, so the printer should proactively provide a safety net, helping the customer avoid compliance pitfalls while also protecting the printer from being held responsible.

The 4 Questions Every Business Owner Should Ask a Printing Company

Finally, here are 4 questions the boss should ask the printing factory to avoid being misled by a “low-price printer.”

1: " ?".",'t,",'t —.

2: " - INCI ?"." "." 't,," -.

3: " / ?"." 's,".

Question 4: “During the proofing and confirmation stage, do you have the customer confirm every label field in writing?” This is the final line of defense for compliance. If the printer answers, “We only need to check the appearance of the proof; there is no need to confirm it word by word,” it means that the risk exposure has not been closed.

After asking these 4 questions, you can basically determine whether this printing company is a cosmetics label supplier that helps you clear regulatory hurdles or simply prints your boxes.Bosses do not need to memorize every regulation. Ask the right questions, and the printer will know you understand the industry and will not cut corners.
