Costa Rica CABYS Code Lookup: Description, Category Path and Tax Rate for a 13-Digit Code (Hacienda)

haciendacr/cabys-by-code

Looks up one entry of Costa Rica's Catalogo de Bienes y Servicios (CABYS), the product and service classification used on electronic invoices, by its 13-digit code: the description in Spanish, the classification path and the tax rate (a percentage such as 13). A well-formed code that is not in the catalogue returns an empty list rather than an error. Use the search tool to find a code from a description. Data from the Ministerio de Hacienda de Costa Rica, passed through unmodified and served by Eden Engine; not an official Ministerio de Hacienda product.
