Please refer to the HS/CA Product Code Checker to do a quick search for the HS codes, product codes and descriptions of a product within our online version of the Singapore Trade Classification, Customs and Excise Duties (STCCED). Alternatively, as the HS is internationally harmonised at the 6 digit level, you may use the HS code provided by your overseas supplier as a reference to determine the 8 digit HS code applicable to your product via the resources mentioned.
