Myth: The Marketplace Handles Cosmetic Compliance for You

Somewhere along the way, a lot of makers picked up the idea that because a big marketplace lets you list a cosmetic product, the marketplace has already checked it's legal to sell. It hasn't. Etsy, Amazon, and similar platforms are storefronts, not regulators, and the compliance obligation sits entirely with you as the seller.

Where this belief comes from

It's an understandable mistake. These platforms do have their own content policies, they'll pull listings that make egregious medical claims, and some have terms of service that mention you're responsible for legal compliance. That last part is the tell: the platform's terms are telling you that you're responsible, not that they've checked for you. A policy that says "sellers must comply with applicable law" is not the same as the platform verifying you actually do.

What the marketplace is not doing

• It is not filing your Cosmetic Notification Form with Health Canada.
• It is not checking your ingredient list against the Cosmetic Ingredient Hotlist.
• It is not verifying your label is bilingual if you're selling into Canada.
• It is not confirming your fragrance allergen disclosures are correct or complete.
• It is not distinguishing for you whether your soap counts as a cosmetic because of the claims you've made on the listing.

All of that is on you, the same as if you were selling from your own website. The only thing that changes with a marketplace is where the transaction happens, not who's answerable for the product being lawfully sold.

The soap claim trap, specifically on marketplaces

This one comes up a lot. A true soap, meaning an alkali salt of fatty acids sold purely on a cleansing claim, can sit outside typical cosmetic regulation in some markets. But the moment your Etsy listing says your bar is "moisturizing" or "clears acne" or "softens skin," you've made a cosmetic claim, and now it's a cosmetic regardless of what the product physically is. Marketplace listing templates often nudge sellers toward exactly this kind of descriptive, benefit-driven language because it sells better, which means the platform's own product-description prompts can quietly walk you across a regulatory line without anyone flagging it.

What actually happens if something goes wrong

If a customer has a reaction, or a regulator does a spot check, or a competitor files a complaint, the marketplace's role is typically to pull the listing and point back to the seller. You're the one who needs to show you notified the product correctly, that your ingredient list is accurate, and that your claims are substantiated. The platform isn't going to produce your CN number for you, because it never had one on file to begin with.

What sellers should actually do

1. Treat a marketplace listing exactly like a listing on your own website: file your CNF, get your CN number, and keep it on record.
2. Read your own product description as a regulator would. Look for words that shift a product from cosmetic to drug territory, or that turn a true soap into a cosmetic claim.
3. Don't assume a marketplace's approval to list means legal clearance. Those are two entirely different gates.
4. If you're selling the same product across your own site and a marketplace, keep your compliance documentation centralized so you're not scrambling to reconstruct it if one channel gets a buyer inquiry or a customer complaint.

The upside of clearing this up early

Once you accept that the platform isn't doing this for you, the actual workload isn't that different from selling any other way. You still need one CNF per product, one accurate ingredient declaration, and marketing language that matches what the product legally is. The myth mostly causes damage by delaying that work until something forces the issue.

Cosmetic Comply exists partly because of exactly this gap: it takes your ingredient list, matches it to INCI and CAS, screens it, has a real reviewer check it, and files the notification, regardless of whether you're selling on your own site, a marketplace, or both.
