K-beauty is one of the biggest forces in the American beauty market. Korean serums, cushion compacts, sheet masks, and sunscreens now sell across Amazon, TikTok Shop, Ulta, Sephora, and U.S. distributors. Demand is not the problem. The problem is that most Korean brands plan their U.S. entry around Korean rules — and Korean rules end at the border.

This guide is written for the Korean brand owner planning a U.S. launch: what MoCRA requires of you, where Korean and U.S. rules diverge, and the specific mistakes that catch Korean brands. For the full compliance picture, start with the MoCRA Compliance Guide for Cosmetic Brands.

The core rule: Korean compliance does not transfer

Everything in this guide follows from one fact: FDA does not recognize Korean compliance as a substitute for U.S. compliance. Specifically:

Your MFDS (Ministry of Food and Drug Safety) approvals and notifications have no standing with FDA. They prove you can legally make and sell cosmetics in Korea under the Korean Cosmetics Act; they satisfy no U.S. filing requirement.
Your Korean functional cosmetics status — whitening, wrinkle improvement, UV protection — means nothing as a cosmetic category in the U.S. FDA has no “functional cosmetics” class. Your product is a cosmetic or a drug, and FDA decides which based on your claims — and, as Step 4 explains, most functional categories land on the drug side.
Korean product registrations and labelling approvals do not transfer. The U.S. runs its own facility registration and product listing systems.
Export certificates, including a Certificate of Free Sale, are supporting paperwork for customs and buyers. They are not FDA filings.

Plan your U.S. launch as a fresh compliance project, not an extension of your Korean paperwork.

Step 1: Register your facility with FDA

If your products are manufactured or processed in Korea (or anywhere outside the U.S.) for sale in America, the facility must register with FDA. Key points for Korean brands:

You need an FEI number first. The FDA Establishment Identifier is required before registration can be filed. Request it from FDA by email; processing typically takes 7 to 10 business days. Run the free FEI check to see whether your facility already has one.
Registration is filed through Cosmetics Direct, FDA’s online portal, using Form FDA 5066. The step-by-step process is covered in Cosmetics Direct: How to Register Your Facility.
Registration renews every two years, based on your facility’s initial registration date, with automated reminders from FDA. See MoCRA Biennial Renewal Explained.
Using a contract manufacturer? The facility that manufactures the product is the one that registers. Most K-beauty brands are made by OEM/ODM manufacturers such as Cosmax or Kolmar Korea — if one of them makes your products, that facility registers (and it needs its own U.S. agent). See Private Label Cosmetics: Who Registers Under MoCRA.

A common Korean-brand mistake: assuming your OEM’s export paperwork covers you. Large Korean manufacturers ship all over the world and may already be FDA-registered — but their registration covers their facility, not your brand’s obligations, and it does not make your products listed or your labels compliant. Confirm exactly what your manufacturer has filed, and what remains yours.

Step 2: Name a U.S. agent

Every foreign facility registering with FDA must designate a U.S. agent: a person or business physically present in the United States who serves as FDA’s official contact for the facility. This is not optional, and neither a Korean address, a virtual mailbox, nor your U.S. importer can fill the role.

The agent receives FDA correspondence, relays it to you, and is the contact FDA reaches out to with questions about your facility. Our own service is flat pricing: $450 one-time plus $34.99 per month per facility. For how to evaluate providers, see How to Choose a MoCRA U.S. Agent and Who Can Be a MoCRA U.S. Agent.

One Korea-specific wrinkle: if your brand is made by an OEM, the agent designation sits with the manufacturing facility’s registration. Brand owners should know who their manufacturer’s agent is — and if you move production to a different facility, the new facility needs its own registration and agent before it ships.

Step 3: List your products

Each cosmetic product sold in the U.S. must be listed with FDA through Cosmetics Direct (Form FDA 5067), filed by the responsible person — the manufacturer, packer, or distributor whose name appears on the label. Listings include product and ingredient information and must be kept current with annual updates.

Note the difference from Korea: the U.S. listing is a separate federal filing in a different format, and neither system recognizes the other. An MFDS notification or a listing with your Korean distributor does not carry over. For how registration and listing differ, see Facility Registration vs Product Listing Explained.

Step 4: Fix your labels — and your claims — for the U.S. market

Korean labels do not automatically comply with U.S. labeling law. The differences that matter most:

Ingredient declaration. The U.S. uses INCI-style nomenclature, so your ingredient names mostly transfer. But the U.S. requires ingredients in descending order of predominance with specific formatting rules, and FDA is developing fragrance allergen labeling regulations that will add new disclosure requirements.

Net quantity. U.S. consumer commodities must state net quantity in both U.S. customary and metric units, placed in a specific location on the principal display panel. Korean labels showing metric only need updating.

Name and place of business. The label must show the name and place of business of the manufacturer, packer, or distributor. A Korean address alone is acceptable only if the product is not misleading about origin; many Korean brands add their U.S. distributor’s information.

Domestic contact for adverse events. MoCRA requires labels to carry a U.S. domestic contact — address, phone number, or electronic contact such as a website — for adverse-event reports. A Korea-only contact does not satisfy this.

Language. All required label information must be in English and must be prominent and conspicuous. Korean text can appear, but never as a substitute. (Products also regulated as drugs need Drug Facts labeling and specific warnings instead.)

Claims review. This is where Korean brands get hurt most — see the next section. Claims are judged by intended use as read from your label, listing copy, and ads. See Is Your Product a Cosmetic or a Drug?.

The pitfalls that catch Korean brands specifically

The functional cosmetics trap. Korea’s functional cosmetics system lets MFDS-reviewed products claim whitening, wrinkle improvement, and UV protection as cosmetics. The U.S. has no equivalent category. In the U.S., a product intended to whiten or lighten skin, to reduce wrinkles by affecting skin structure, or to protect against the sun is a drug — and every sunscreen sold in the U.S. is an over-the-counter drug, full stop. Drug products follow a different pathway entirely: drug establishment registration, drug listing, and Drug Facts labeling, not MoCRA cosmetic filings. Many K-beauty bestsellers — brightening serums, anti-wrinkle creams, and Korea’s famously elegant sunscreens — cannot simply be relabeled and shipped as cosmetics. Classify every product before anything else.
FDA import refusals at volume. Korean cosmetics manufacturers appear regularly in FDA import refusal records, and shipments from unregistered or misbranded facilities can be detained at the port under import alert. A detention costs weeks, storage fees, and sometimes the whole shipment. If your products are stopped, read FDA Detained Your Cosmetic Shipment? — but the cheaper move is getting the filings right before the first container leaves Incheon.
Assuming your OEM’s paperwork covers your brand. Cosmax, Kolmar Korea, and other large OEM/ODM manufacturers export worldwide and handle their own facility compliance. That does not list your products, fix your claims, or make your labels legal. The brand owner’s obligations are the brand owner’s.
Assuming a marketplace listing means compliance. Many Korean brands sell on Amazon USA or TikTok Shop and assume a live listing means the regulatory side is handled. It does not: Amazon’s checks are Amazon’s, and FDA’s requirements apply regardless. See Selling Cosmetics on Amazon: FDA Requirements.
Small-business exemption confusion. The U.S. small-business exemption (Section 612 of the FD&C Act, 21 U.S.C. section 364h) is based on U.S. sales, not Korean revenue, and it never exempts labeling, safety substantiation, or adverse event reporting. Check the exemption worksheet rather than assuming.
Forgetting the ongoing duties. Registration is not a one-time event: biennial renewal, annual listing updates, adverse event reporting within 15 business days for serious events, and records kept for six years that FDA can demand to see. See MoCRA Adverse Event Reporting.

A realistic Korea-to-US launch sequence

Classify every product as cosmetic or drug for the U.S. market (re-do the claims first — functional cosmetics need this decision before anything else).
Confirm whether you qualify for the small-business exemption; if not, proceed with full compliance.
Request your facility’s FEI number (7 to 10 business days) — or confirm your OEM facility already has one.
Choose and appoint your U.S. agent (through the manufacturing facility’s registration).
File facility registration via Cosmetics Direct.
File product listings.
Finalize U.S.-compliant labels before the first shipment.
Set up adverse event intake and record-keeping from day one.

FAQ

Does my MFDS approval count for anything in the US?
No. Korean approvals under the Cosmetics Act have no standing with FDA, the U.S. has no functional cosmetics category, and your registration, agent, listings, and labels must all be done under MoCRA (or the drug rules, where they apply) regardless.

Is my sunscreen a cosmetic or a drug in the US?
A drug. Every sunscreen sold in the U.S. is an over-the-counter drug, as are products claiming to whiten skin or reduce wrinkles by changing skin structure. Those products need drug registration, drug listing, and Drug Facts labeling — a different filing pathway from MoCRA cosmetics compliance. Ordinary moisturizers and cleansers with cosmetic-only claims stay cosmetics.

Do I need a U.S. agent if my OEM already exports to America?
The manufacturing facility must designate a U.S. agent as part of its FDA registration — if your OEM manufactures your products, the agent sits on their facility registration. But your OEM’s agent and registration do not cover your brand’s product listings, claims, or labels. Confirm who their agent is and what their registration covers; the rest is still yours to file.

Are Korean cosmetic labels acceptable in the US?
Usually not without changes. Net quantity declarations, the domestic adverse-event contact, name and place of business, warning statements, and claims all need review against U.S. requirements. Ingredient nomenclature mostly transfers, but formatting rules differ — and Korean-language text can never substitute for the required English information.

How long does the whole process take for a Korean brand?
The FEI request alone takes 7 to 10 business days, and gathering registration details, appointing an agent, and finalizing labels adds more time. Plan for several weeks minimum from a standing start; see How Long Does MoCRA Facility Registration Take? for the full breakdown.
