Supplier Document Checklist to Complete Before Filing

Half the delay in most first-time filings isn't the regulator. It's realizing halfway through that you're missing a document for one ingredient out of fifteen, and now you're emailing a supplier who takes four business days to respond. Getting your documents lined up before you start the actual filing saves that entire cycle.

Here's what to have on hand, per ingredient, before you sit down to file.

The core documents, ingredient by ingredient

For every single ingredient in your formula, including the ones you consider minor:

• Safety Data Sheet (SDS). Sixteen sections, with section 3 giving you composition and CAS numbers. Confirm it's current, matching the exact product code and batch you're using.
• Certificate of Analysis (COA), if available. Not always mandatory, but useful as a cross-check against the SDS, especially for natural extracts where composition can vary batch to batch.
• Confirmed INCI name. Not the trade name, not your own shorthand for it. If the supplier's paperwork doesn't clearly state the INCI name, you need to resolve it yourself using the CAS number as your anchor.
• Concentration or use level. Either the percentage in your finished formula (for raw ingredients you add directly) or the blend's internal composition percentages plus your use level of the blend (for anything that's a supplier mixture).

A one-page checklist format

Use something like this per ingredient, and don't consider a formula filing-ready until every row is filled in:

Item	Have it?	Notes
SDS current and matches product code		Check revision date
INCI name confirmed		Not trade name
CAS number confirmed		Some botanicals have none, note if so
Concentration in finished product		Exact figure, not a range if avoidable
Blend components identified (if applicable)		List each component's % within the blend
Language readable (English, or French for Canada)		Request official translation if not
Restricted-list screening done		Cross-check against target market's list

Print that, or keep it as a spreadsheet template, and run every ingredient through it once before you touch the actual notification form.

Why blends deserve their own line item

A single line on your formula sheet, like "preservative blend, 1%," can hide three or four actual chemical components once you open the SDS. Each of those components needs its own INCI name, its own CAS number where applicable, and its own calculated concentration in your finished product, found by multiplying the component's percentage within the blend by your 1% use level.

Skipping this step is the single most common reason a filing looks complete on the surface but isn't. The formula sheet says "preservative blend" and everyone assumes that's descriptive enough. It isn't, for regulatory purposes.

What "filing-ready" actually looks like

You're ready to file when:

1. Every ingredient, including minor additives and blend components, has a confirmed INCI name.
2. Every ingredient has a CAS number or a documented reason it doesn't have one.
3. Every concentration is either an exact figure or a conservative estimate you're comfortable defending.
4. You've screened the full list against your target market's prohibited and restricted substances (in Canada, that means the Cosmetic Ingredient Hotlist).
5. Any fragrance components have been checked against relevant allergen disclosure thresholds, since several markets are tightening these requirements.
6. Language and format match what your target regulator expects, bilingual labeling included for Canada.

Skipping this step costs more time than it saves

It's tempting to start the filing form first and chase down missing documents as you hit them. In practice this usually means starting the same ingredient's paperwork trail two or three separate times instead of once, because you didn't have the full picture when you first went looking.

This kind of pre-filing organization is the exact gap Cosmetic Comply is meant to close. It takes your ingredient list and supplier documents, maps every ingredient to its INCI name and CAS number, expands blends into real percentages automatically, and flags gaps, like a missing CAS number or an unscreened ingredient, before you're stuck mid-filing wondering what's missing. A real compliance reviewer checks the result before anything is submitted, so the checklist above becomes something the system verifies with you rather than something you're tracking alone in a spreadsheet.
