TASTE for GTAP 12
TASTE uses the International Trade Centre (ITC) Market Access Map (MacMap) trade flows and applied tariff data. Tariff simulations for applied tariff rates can be conducted using the "A" series of tariff rules (AEQUALS, AMIN, ASWISS, AFSWISS, AGIRARD, ALINEAR and ATIERED).
This version includes applied and bound tariff rates as well as the corresponding bilateral and reference group weighted trade flows for the year 2023. The dataset is based on, and broadly consistent with, the ITC Market Access Map tariff database employed in GTAP 12 (February 2026).
Compared to the standard GTAP tariff database, TASTE remains closer to the original HS-level tariff information from ITC Market Access Map. Consequently, tariff rates may differ from those reported in GTAP due to aggregation and balancing adjustments applied during GTAP database construction.
The Sens.har file has been updated and mapped to the GTAP 12 sectoral and regional aggregation but no predefined sensitive products are included in this file.

TASTE for GTAP 11
TASTE uses ITC MacMAP flows and applied tariffs. You can run a TASTE tariff simulation using the "A" series of tariff rules [AEQUALS, AMIN, ASWISS, AFSWISS, AGIRARD, ALINEAR and ATIERED], which changes applied rates. This TASTE version includes applied and bound tariff rates as well as the corresponding trade flows for the year 2017. The data is based on, and broadly consistent with, the ITC MacMAP tariff dataset employed in GTAP 11.

TASTE is a program, developed by Mark Horridge and David Laborde, that reads from the MAcMapsHS6 data, produced by ITC-Geneva. The TASTE program addresses two needs of GTAP users:
- To prepare files of tariff shocks where GTAP users need information about bound rates (not part of GTAP) and applied rates at a detailed sectoral level (HS6).
- To provide tariff data for SplitCom, which allows you to split one or more of the supplied GTAP sectors.
The TASTE program itself reads the enormous MAcMapHS6 dataset and performs various operations, in particular:
- Transformation of scenarios about formula-based changes in bound rates into files of percent change shocks to applied rates which could be used by RunGTAP.
- Generation of matrices of splitting weights which could be used to split a sector in the trade matrices of a GTAP Model Data Base (maybe using the SplitCom method).
