Why FDA Detains Korea-Made Cosmetics: Import Alerts for Founders

A shipment reaches a US port, and instead of a delivery date your importer forwards a Notice of FDA Action. For brands that make product in Korea, that notice rarely comes out of nowhere. FDA publishes the reasons it stops cosmetics at the border, and it publishes the products and firms it has already flagged, country by country.

This guide reads those lists for Korea, explains detention, refusal, and import alerts, and ends with the checks to run with your ODM before the purchase order.

Why Does FDA Detain Cosmetics Made in Korea?

FDA detains a cosmetic shipment when it appears to break US law, and the legal test is appearance, not proof. The import section of the Food, Drug, and Cosmetic Act uses those words. A product is refused if it “appears from the examination of such samples or otherwise” to be adulterated or misbranded (21 U.S.C. 381). Imported cosmetics follow the same rules as products made in the US.

FDA lists the most common refusal reasons on its Cosmetics Importers page:

• Ingredients or contaminants that make the product unsafe.
• Color additive violations.
• Prohibited or restricted ingredients.
• Microbial contamination.
• Labeling gaps, such as an incomplete ingredient declaration or required information missing in English.
• Claims that turn a cosmetic into a drug under US law.

Not every box gets opened. FDA uses import alerts to focus examinations, and says a product never detained before can still be detained later.

Detention, Refusal, and Import Alerts Compared

Detention, refusal, and an import alert are three different steps, and founders often mix them up. Detention is a hold on one shipment while FDA decides. Refusal is the final decision that the shipment cannot enter. An import alert is guidance to FDA field staff that lets them detain named products from named firms without physical examination.

DWPE refers to that last practice: detention without physical examination.

A listing can come fast. The microbial alert states that a firm's product can be recommended for the Red List after one violative entry when FDA's other criteria are met.

What Puts a Korean Product on Import Alert 53-06?

Import Alert 53-06 covers cosmetics that are adulterated or misbranded because of color additive violations. The alert sorts color problems into three types. A “non-permitted” color is unapproved or used outside its approved use. An “uncertified” color needs FDA batch certification but has no valid certification lot number. An “undeclared” color is missing from the label (Import Alert 53-06).

The Korea section of the alert's Red List repeats a handful of product patterns (firm and brand names left out):

• Eye products. Eye shadows, eyeliners, and brow tint packs with colors that are not permitted in the area of the eye, such as D&C Red No. 30, FD&C Yellow No. 6, and a carbon black grade listed as channel black.
• Lip tints and crayons. Several entries list four or more flagged colors on a single shade.
• Sleeping masks. FD&C Yellow No. 5 and D&C Red No. 30 marked as non-certified.
• Lash glue and hair color rinses. Carbon black in adhesives, and dyes not permitted in the US.
• Specialty colorants. Gold, silver, charcoal powder, and squid ink melanin were each listed as non-permitted.

Two rules sit behind most of these entries. A color allowed in Korea or the EU is not automatically allowed in the US, and US approval is use-specific. D&C Black No. 2, a high-purity carbon black, is permitted in eyeliner, mascara, eye shadow, and brush-on-brow, but every batch must be FDA certified (21 CFR 74.2052).

The label is the second half. FDA does not accept Color Index (CI) numbers alone on US labels. The US color name comes first, with the CI number in parentheses if you want it, and a CI number does not show FDA approval or certification. Lip products add their own color limits, covered in the lip treatment development guide.

Microbial Contamination Is the Second Pattern

Import Alert 53-17 covers cosmetics detained for microbiological contamination, and Korean firms appear on it too. FDA's standard in the alert is short. Cosmetics must be completely free of high-virulence microbial pathogens, and aerobic counts per gram must be low (Import Alert 53-17).

The Korea entries are water-rich, eye-area, or single-use formats: hydrogel eye patches, facial mask packs, mascara, eye shadow, and eyelash kits. Organisms recorded include Pseudomonas, Staphylococcus aureus, Burkholderia cepacia, and yeast and mold.

Release takes evidence. For a detained shipment, the alert points to a private lab analysis of a representative sample with at least five sub-samples, such as five retail units. Removal from the Red List takes more: satisfactory third-party results on the detained product from each of five consecutive shipments.

Your ODM's micro and preservative efficacy reports are the first line of defense. The stability and challenge test report guide shows how to read them before production.

When Does a Skincare Claim Trigger the Drug Alert?

A claim triggers the drug alert when it says the product treats, prevents, or changes the body, because that makes it a drug under US law. Import Alert 66-41 covers unapproved new drugs promoted in the US. Its Korea section includes hair-loss shampoos, anti-blemish masks, SPF sun creams, dark-spot creams, and acid toners sold with treatment claims (Import Alert 66-41).

Those SKUs follow drug rules, not cosmetic ones. The OTC acne product steps show what that path involves.

Five Steps After a Notice of FDA Action

A Notice of FDA Action names the charge and the response window, and your reply has to match both. The sequence below follows FDA's import regulations:

1. Read the charge. Pull the formula sheet, label proof, and lot documents from your ODM the same day.
2. Respond in the window. Testimony and evidence go in at the time and place the notice specifies (21 CFR 1.94).
3. Apply to fix it. If relabeling or another fix can bring the goods into compliance, apply for authorization. The owner or consignee files a plan, location, and timeline on Form FDA 766 (21 CFR 1.95).
4. Export or destroy if refused. Refused goods are destroyed unless exported within 90 days of the refusal notice or any extra time allowed (21 U.S.C. 381).
5. Fix the cause. Correct the formula, label, or claims before the next PO, and keep the evidence file for future entries.

Your customs broker files the entry, but what to submit to FDA is a regulatory call. Bring in a regulatory advisor early.

How Do You Check FDA's Lists Before a PO?

Check two free public sources before the PO: FDA's import alert pages and its import refusal data. Both show what FDA has already flagged.

• Import alerts by country. FDA's Korea page lists every import alert with Korean entries, including 53-06, 53-17, and 66-41. Search each Red List for your factory's name and for the product type you plan to make.
• Import refusals. The FDA Data Dashboard lets you filter refusals by product category and country. Choose cosmetics, choose Korea, set a date range, and read the refusal charges. Note the period you pulled, because the data covers final actions only and refreshes over time.
• The ODM itself. Ask in writing whether the factory has received a Notice of FDA Action on any US shipment, and ask for the corrective records if so.

A Red List entry for your product type is a reason to stop and ask before money moves.

Pre-PO Checklist for Korea-Made Cosmetics

Run these checks with your ODM before you sign the PO, and keep the answers in one file per SKU. Each line maps to a refusal reason FDA lists.

Frequently Asked Questions

Can a Korean product be detained if it was never detained before?
Yes. FDA states that a clean history does not protect a product from future detention if it appears to violate US law. Examinations are not limited to products named in import alerts.

Does a CI number on the label prove a color is approved?
No. FDA says CI numbers do not indicate FDA approval or color certification, and they are not acceptable on US labels unless the US color additive name comes first. The color must also be approved for the specific use, such as the eye area.

Who receives the Notice of FDA Action, the factory or the brand?
FDA sends the notice to the owner or consignee of the shipment, which is often the importer rather than the Korean factory. Ask your broker to forward any notice the day it arrives, since the notice sets the response window.

How does a factory get off an import alert?
The firm petitions FDA with evidence that the problem is resolved. For the microbial alert, FDA asks for satisfactory third-party test results on the detained product from five consecutive shipments. For the color additive alert, FDA points to Chapter 9-8 of its Regulatory Procedures Manual.
