Not the same as tarkov.dev's curated "Loot tiers" page - that ranking is hand-maintained by their team, and isn't available through this app's data source. This is a locally computed substitute: every flea-tradable item ranked by flea value per kilogram (a rough "worth carrying" measure), bucketed into 5 tiers by percentile. Treat it as a starting point, not a definitive ranking - it doesn't account for slot efficiency, quest/hideout use, or trader-only value.
