The Information Checklist to Gather Before Filing a CNF

Most CNF filings that drag on aren't stuck because of anything complicated in the regulation. They're stuck because somebody sat down to file and realized they didn't have the exact concentration range for one ingredient, or nobody had confirmed which entity name should legally be listed as the notifier. Gathering everything up front turns a filing that could take a while into one that takes an afternoon.

Why this matters more than it seems

The Cosmetic Notification Form has to be filed through the Cosmetic Notification System within 10 days of first sale. That's not a long runway if you're starting the information-gathering process after you've already started selling. Health Canada issues a Cosmetic Notification number once the filing goes through, and that CN number is your proof the product was properly notified, but you can't get there without the underlying data being accurate and complete first.

The core checklist

Company and contact information

• Legal company name exactly as it should appear on the notification
• Full mailing address
• A contact person and reachable contact details for follow-up questions

Product identity

• The product's exact name as it will appear on the label
• The product's function or category (for example, moisturizer, shampoo, lip balm)
• Whether this is a genuinely new product or a variant of something you've already filed, since duplicating a past filing can save real time on near-identical formulas

The complete formula, by INCI name

This is where most of the actual work lives. For every ingredient in the formula:

• The correct INCI name, not the trade name or the supplier's internal code
• The concentration or concentration range in the finished product
• For any supplier blend, its expanded component ingredients, with each component's real concentration calculated by multiplying its percentage within the blend by the blend's use level in your formula

Fragrance allergen data, if applicable

If your formula includes fragrance materials or essential oils, check what fragrance allergens are present and at what concentration. Disclosure becomes mandatory for List 1 allergens (the original fragrance allergen set) on the CNF and label starting April 12, 2026, with List 2 (an expanded, internationally aligned set) becoming mandatory August 1, 2026. Thresholds are above 0.001% (10 ppm) in leave-on products and above 0.01% (100 ppm) in rinse-off products. Common allergens like limonene, linalool, citronellol, geraniol, eugenol, and coumarin occur naturally in a lot of essential oils, so check your natural fragrance components carefully, not just any added fragrance blend.

Hotlist check

Cross-reference your full ingredient list, at actual finished-product concentrations, against the current Cosmetic Ingredient Hotlist for anything prohibited or subject to a concentration ceiling.

A quick reference table

Category	What to have ready	Common trip-up
Company details	Legal name, address, contact	Using a trade name instead of the legal entity name
Product identity	Name, function, new vs. variant	Not checking if a near-identical product was already filed
Formula	INCI names, concentrations, expanded blends	Filing a trade name instead of the mapped INCI name
Allergens	Fragrance allergen presence and level	Missing allergens naturally present in essential oils
Hotlist	Cross-check at true finished-product concentration	Checking the ingredient's raw percentage in a blend, not its diluted percentage in the final product

What happens after you file

Filing isn't the end of the relationship with your CNF. If your formula changes, even a modification to an existing ingredient's concentration, you file an amendment. If you discontinue the product, you file a discontinuation. Keeping your original filing information well organized makes both of those follow-up filings much faster, since you're updating a known baseline rather than reconstructing it.

Building this list is genuinely the hard part

None of the individual pieces on this checklist are difficult in isolation. The friction comes from doing all of it accurately, for every ingredient, including the ones buried inside a supplier blend you haven't looked closely at in months. That's the exact gap Cosmetic Comply is built to close: you give it your product and ingredient list, it maps everything to INCI names and CAS numbers, expands blends and carries the real percentages through, screens against the Hotlist with a confidence score, has a compliance reviewer check the result, and files the CNF, returning your CN number at the end. If you've already filed something similar before, it can duplicate that past filing for a minor variant instead of starting from zero.
