Marketplace Tax Collection vs Cosmetic Compliance

A maker messaged us last month asking why she needed to "register her products" when Etsy already collects and remits sales tax for her orders. She had genuinely conflated the two, and honestly, it's an easy mix-up. Both involve paperwork, both involve a platform, and both sound like "the government wants proof you're doing this right." But they are entirely separate systems answering entirely separate questions.

What marketplace tax collection actually does

Marketplace facilitator laws exist to make sure sales tax gets collected somewhere, since tracking down thousands of individual small sellers is a nightmare for tax authorities. So platforms like Etsy, Amazon Handmade, and Shopify's tax add-ons calculate, collect, and remit sales tax on the transaction itself. It is about the sale of goods, full stop. The platform doesn't look at your ingredient list, doesn't care if your lavender lotion contains a botanical extract that needs INCI mapping, and has no mechanism for checking whether your product is legally allowed to be sold at all.

That distinction matters because sellers sometimes read "tax handled" as "compliance handled." It isn't. A marketplace collecting 8% sales tax on your order has zero relationship to whether your product's ingredients have been screened against a prohibited substances list or whether the government even knows your product exists.

What product-safety compliance actually does

This is the part that has nothing to do with money moving between buyer and seller. It's about whether the product itself is safe and properly disclosed. In Canada, for example, cosmetic sellers file a Cosmetic Notification Form through the Cosmetic Notification System, a NOTIFICATION rather than an approval, due within 10 days of first sale. That filing lists every ingredient by INCI name with concentration, gets checked against Health Canada's Cosmetic Ingredient Hotlist, and results in a Cosmetic Notification number tied to that specific formula.

None of that lives inside your Etsy shop settings or your Shopify tax dashboard. It's a separate regulatory relationship between you as the seller and the government body overseeing cosmetic safety, completely independent of which marketplace you happen to sell through.

Why the confusion happens so often

A few reasons this mix-up is common among newer makers:

• Both processes involve forms, portals, and identifying numbers, so they feel structurally similar.
• Marketplaces do enforce some rules (banned ingredient lists, prohibited claims language) which can feel like a compliance check even though it's really just platform policy, not government notification.
• New sellers often onboard tax collection first because the platform prompts them to during setup, creating a false sense that "the hard part" is done.
• Neither process is visible to the end customer, so there's no obvious signal telling you which boxes are actually checked.

A simple way to keep them separate in your head

Question	Who answers it	What it's called
Did I collect the right sales tax on this order?	Your marketplace or ecommerce platform	Tax remittance
Is my formula screened and disclosed to the regulator?	You, as the seller, directly to the government body	Cosmetic notification
Do I have a bilingual label with the ingredient list in the right order?	You	Labeling compliance
Is my facility registered and my formula's safety substantiated?	You (market-dependent, e.g. MoCRA in the US)	Facility/product registration

Selling on five marketplaces simultaneously doesn't multiply your notification duty. It's still one product, one formula, one notification per market you sell into. But it also doesn't reduce it. Being a "small Etsy shop" doesn't exempt you from notifying just because the volume feels hobbyist-scale.

What to actually check before you scale up

If you're selling handmade cosmetics anywhere online, worth confirming for each market you ship to:

1. Whether your product legally counts as a cosmetic (a soap with a moisturizing or anti-acne claim usually does, even if it started life as "just soap").
2. Whether that market requires a notification, registration, or listing, and what the deadline is after first sale.
3. Whether your label meets that market's language, ingredient-order, and allergen disclosure requirements.
4. Whether you've mapped every ingredient, including supplier blends, to its correct INCI name.

None of that shows up on a tax dashboard, and none of it gets handled by the marketplace on your behalf. Cosmetic Comply was built for exactly this gap. It takes your ingredient list, maps everything to INCI and CAS, screens against the relevant prohibited and restricted lists, has a real reviewer confirm it, and files the notification for you, separate entirely from whatever your sales channel is doing with tax. Worth setting up before your next product launch rather than after a customer or regulator asks about it.
