It is a document for the result of the tariff issue in November 2011. It seems that supplier had used a wrong HS code (coordinates), and that is why there is an issue to be resolved. the document does not conclude that the LED tube belongs to HS 8543, as the last column Guidelines just indicates what the HS 8543 is for machinery and other equipment that function independently. the coloum product and description indicate the results of the finding what the product is. Does not conclude that it is ok to be used as HS 8543.
