This includes only expenditures on inspection of domestically produced commodities at first level of processing and border inspection for exported commodities. Import control activities are not included. Production and trade data may be used to make an approximate estimation of a differentiation between export and import inspections. In case that such a separation is not possible, the entire expenditure on food safety and inspection should be included and mention should be made in the documentation. Water subsidies granted to individual farmers and investment subsidies to on-farm irrigation infrastructure are included in the PSE. In the case of large investments, such as dams, with multiple outputs (irrigation, water retention, flood prevention, hydro-energy), the GSSE accounts only for the share of the outputs used by primary agriculture.
