Sampling for Realisation-The Practice in Japan

Most mineral products exported from Australia to Japan, with the notable exception of coal, are purchased with weight and quality determined on discharge. Sampling of imported minerals for purpose of payment is done at facilities owned and operated by the purchaser. The selling shipper is represented at the weighing, sampling and testing by an independent inspection group who supervises the whole procedure. Sampling and testing are done within the provisions of the contract between the two parties, and normally in accordance with the relevant Japanese Industrial Standards (JIS). These JIS specify such things as the number and mass of increments to be taken; the practice of taking these increments; the method of determination of moisture, size distribution and quality. The JIS concerned with sampling however, are meant to be basic guides rather than rigid rules. Hence sampling and testing practice varies from plant to plant. In general Japanese sampling facilities and methods are elaborate and efficient. Opportunity is given for the discussion of varying technical viewpoints between consumer and shipper. However the resolution of differences and the implementation of changes normally takes a long time. Such discussions seem best reduced by prior contract agreement on reasonable specifications and detailed testing methods. The independent inspectors
