Also during the nine-month period, 26.59 million tons of goods worth $37.57 billion were imported showing a growth of 18.31 percent against the figure for the same time span last year.

The government has recently limited the hours for registering import orders. Based on the new regulation, importers are required to register their orders online from 8:00 a.m. to 4:00 p.m. every day.
