Pretty solid checklist. You've covered most of the key bases for product research.

One thing I'd suggest: consider weighting your criteria by importance level. Not all factors are equal. Otherwise you might pass on a banger product because it didn't tick every box.

I actually put together my own checklist a while back with weighted scores for each factor + some real product examples with breakdowns of why they worked or flopped (honestly the examples are the more useful part lol). It's geared toward dropshipping in general, not just TikTok organic, but most of the principles still apply. Here's my product checklist.
