How to Evaluate Any Category Before Entering

Before committing to any category for wholesale FBA on Amazon USA evaluate it across the same five criteria regardless of which category you are considering. These criteria determine whether a category is genuinely suitable for wholesale FBA — not just popular or frequently recommended:

Evaluation Criterion	What to Look For
Referral fee rate	Lower referral fees leave more gross margin for your FBA fulfilment fee and net profit — categories with 8% referral fees are structurally more attractive than those with 15% or 17%
FBA size tier of typical products	Categories where typical products fall into the small standard or large standard tier have significantly lower FBA fulfilment fees than oversize-heavy categories
Wholesale supply chain accessibility	Categories with well-developed US wholesale distribution infrastructure — many authorised distributors across price points — are easier to source in profitably than categories dominated by exclusive or restricted distribution
Buy Box dynamics on Keepa	Confirm that typical ASINs in the category show two to six sellers rotating through the Buy Box — stable prices over 12 months — and Amazon not holding the majority of Buy Box time
Brand gating and approval requirements	Some categories and brands require prior approval before a seller can add an offer — gating that is achievable with supplier invoices is workable but categories with widespread impenetrable gating reduce the accessible product pool significantly
