Google refreshes country-specific price tiers and their minimum and maximum bounds periodically, and emerging markets move faster than the majors because of exchange-rate volatility and local tax changes. The practical risk is not the tier table itself but manual price mapping: apps that pinned each in-app product to a specific tier can end up either priced far below the local market or above the ceiling Google will accept.
The first thing to check is Play Console > Monetize > Products > In-app products, then the price template attached to each country. If a product uses a fixed tier rather than automatic conversion, verify that the tier still exists for Brazil (BRL), India (INR) and the Southeast Asian currencies, and that the resulting local price still clears tax-inclusive display rules and any local rounding expectations.
For most accounts the safest configuration is automatic currency conversion with minimum and maximum bounds set per country. That keeps you inside the band Google accepts, follows FX movement without manual work, and avoids the situation where a tier is retired and the product silently stops selling in a market. Set bounds deliberately: a floor that protects margin and a ceiling that keeps the product competitive.
Before shipping a price change, run a sandbox purchase in each affected market and confirm the amount the user sees, the amount Play reports, and the amount your backend receives agree after tax. Also check whether the change affects existing subscriptions: existing subscribers normally keep the price they signed up at until they are notified, and a price increase requires the notice flow.
Finally, keep a written price log (date, country, tier, local price, effective date). When revenue in a market moves unexpectedly, that log is the only way to tell whether the cause was a tier change, an FX move or a promotional campaign.
