There are many problems in export trade data. This give rise to distrust of trade statistics. Most of all we survey random sample to estimate error rate because we don't know how many there are. This error rate for all export data recorded in first half 2004 is estimated by 2% and consists of many items-price, quantity and weight. We adopt to statistical technique so that solve these errors. First, we use an unit of mean price besides of standard price, which can be calculated by HS. This result that detection rate of errors estimated by 11.5%. Second we inspect trade data with fault using regression model.
