Customs expertise can be considered as a special class of examination as it has special tasks and methods of studies. The objects of the Customs expertise are the goods crossing the border or samples of the goods.
Customs expertise
There are rather often cases when unfair exporter/importer tries to declare goods with another code to reduce taxes and duties. It happens often when the visual determination of the goods class is similar (metals for example).Chemical methods of composition analysis are rather long.
X-ray fluorescent method provides rapid Customs expertise for determination of actual goods validity dependent on the type, class grade of material.
Material composition may vary in a wide range, therefore it can be determined by two methods:
In the first case quantitative analysis of the sample is fulfilled with preliminary made calibrations. It is possible when the sample material is close to composition and can be treated the same way as the calibration standards.
In the second case fundamental parameters method (standardless analysis) is applied. It is usually used for metal alloys composition determination, the sample may have any shape within the size of the sample holder.
XRFA provides high validity, multiple examinations; it is simple and clear. Therefore it is widely used in Customs expertise laboratories.
