GTAP Data Bases: What data are not required?

Once accepted your data undergoes a number of changes before being included in the GTAP Data Base (see What happens to my data after it is accepted?). Due to these changes land rentals can be contributed, however they will be replaced. Other data which can be left blank (zeros) are the taxes and import duties.
