An international, non-profit association founded in 1974 under Belgian law.
Developed by the World Customs Organization (WCO), this is a six-digit figure for describing internationally traded goods. Individual countries may further extend this code with an additional two or four digits, however these additional digits are not harmonised and may have different meanings from country to country.
Below is a list of six-digit HS codes known to apply, or to have applied at some time, to niobium and tantalum materials, as well as a selection of variants used in some Customs jurisdictions. Note that these HS Codes may change from time to time, e.g. by WCO review at five-yearly intervals, or as per individual countries.
When referring to country specific eight- or ten-digit codes, cross-reference should be made to the title of the primary four- or six-digit HS code.
