The CCL uses “Customs Analysis methods Information” as the standard analysis methods in order to contribute to the implementation of a unified analysis in Customs. And they are available to the public in terms of transparency.

The CCL is translating these methods into English in order to serve for a reference as good practices of chemical analysis by Customs to other members of the World Customs Organization (WCO), as one of the activities of the WCO Regional Customs Laboratory (RCL). (As for the WCO RCL, please refer to the topic of 12 Nov. 2014 at http://www.customs.go.jp/ccl/e_activities/movement2014.htm#141128)

Now 104 method is newly open. And 302 method is updated to new version. Please refer to the following list.
