In this type of safeguard, an additional duty may be applied if the import price of a designated agricultural product falls below defined trigger price.
Example:  An additional duty of 2.79 Php/kg is applied to a shipment of frozen meat and offal of fowls of the species Gallus domesticus when the c.i.f. import price of that shipment is 20 per cent below the trigger price of 93 Php/kg.
