The site mirrors the PSIC 2019 ladder from section down to subclass so users can narrow codes in a controlled way instead of guessing from a single keyword.
This page is part of an independent reference site. Verify critical tax, registration, legal or reporting decisions against the current official PSA, BSP or BIR source that applies to your workflow.
Start from section pages if you only know the broad industry family. Move to divisions when the field is still wide, then compare groups and classes before landing on a subclass.
If you already know the product, service or business wording, use the PSIC search page first and then confirm the result by checking its parent hierarchy and sibling codes.
This project uses the BSP workbook as the practical operational layer and surfaces any count differences from the PSA public overview rather than hiding them.
Section is the broadest public level and is useful for orientation before narrowing the search.
Those levels are still broad enough to hide important differences. The subclass level usually gives the best practical match.
If you already know the wording, search first. If you only know the broad sector, browse top-down through the hierarchy.
