MoCRA for Amazon and Marketplace Cosmetic Sellers

Picture three sellers on the same marketplace, all listing what looks like the same face serum, and all three having a completely different answer to "who's responsible for MoCRA compliance here." That's not a hypothetical. It's basically every private-label cosmetics category on Amazon right now.

The three seller types and why they diverge

Seller one buys white-label serum from a contract manufacturer, slaps their own brand name on it, and lists it. They didn't formulate anything, but they're the ones whose name is on the label and who decided to bring this specific product to market.

Seller two is reselling an established brand's product they bought wholesale, listing it under that brand's existing name and packaging with no changes.

Seller three is drop-shipping, meaning they never touch the physical product; a third party ships it directly to the customer under the seller's storefront listing.

Under MoCRA (the Modernization of Cosmetics Regulation Act, 2022), the responsible person is generally the manufacturer, packer, or distributor whose name appears on the label. For seller one, that's almost always them. They chose to put their brand name on someone else's formulation, and MoCRA's structure puts the compliance weight on whoever's name the consumer sees on the product, not on whoever mixed the batch.

For seller two, if they're reselling under the original brand's name and label without alteration, the responsible person is generally whoever's name is actually on that label, meaning the original brand, not the reseller. This is why private labeling versus straight reselling is such a meaningful distinction. Changing the label to your own brand is what pulls the compliance obligation onto you.

Seller three is the messiest case in practice, and it's exactly the kind of scenario where the label details and the actual business arrangement need to be looked at together rather than assumed.

Facility registration and product listing

MoCRA requires facility registration and product listing with the FDA, alongside a named responsible person, safety substantiation, and adverse event recordkeeping. For a private-label seller who never manufactures anything themselves, the facility registration obligation typically falls on the contract manufacturer that actually produces the product, while the product listing and responsible person obligations tend to track back to whoever's brand is on the label.

It's worth noting MoCRA includes exemptions for some small businesses from registration and listing requirements, so the size and structure of the specific business matters here too, not just the seller-manufacturer-brand relationship. That's a detail worth confirming against current FDA guidance for your specific situation rather than assuming either way.

Where marketplace sellers commonly get it wrong

• Assuming that because Amazon required documentation to approve the listing, MoCRA obligations have somehow already been satisfied. Marketplace onboarding and federal regulatory compliance are unrelated processes.
• Private-label sellers assuming their contract manufacturer's registration covers everything, when the responsible person and listing obligations typically follow the label, not the factory.
• Not having a real conversation with the contract manufacturer about who is filing what, and discovering the gap only when asked for documentation later.
• Treating "the supplier said it's compliant" as equivalent to having actually confirmed a named responsible person and safety substantiation exist for the specific labeled product.

A basic sequence for sorting this out

1. Pull up the actual product label as it will appear to the customer and identify whose name and address are on it.
2. If it's your brand name, you are very likely the responsible person under MoCRA's framework and need to have safety substantiation and recordkeeping in place.
3. If it's someone else's brand name that you're reselling unchanged, confirm directly with that brand (or through your supplier agreement) that they've handled registration and listing.
4. For drop-shipping arrangements, get this in writing with whoever is actually fulfilling the product, since verbal assumptions about who's "handling compliance" tend to fall apart exactly when someone asks for documentation.
5. Don't assume sunscreen, anti-acne, or other drug-adjacent products in your catalog follow the same path. Sunscreen specifically is regulated as an OTC drug in the US, not a cosmetic, which is an entirely separate framework from MoCRA.

Why this is worth sorting out before an issue, not after

The responsible person designation isn't just a paperwork formality. It's the name the FDA looks to and the party who's expected to maintain adverse event recordkeeping and safety substantiation. If you're a marketplace seller who put your brand on someone else's formulation, that responsibility most likely sits with you, whether or not you were the one who thought through the ingredient safety in the first place.

Cosmetic Comply is currently focused on Canada's Cosmetic Notification Form process, with US MoCRA support on the roadmap. For sellers running products into both markets, the underlying discipline is the same either way: know exactly what's in your product down to the INCI and CAS level, and know exactly whose name and legal obligation sits behind the label before you list it anywhere.
