The Harmonised Commodity Description and Coding System, also known as the Harmonised System (HS) of tariff nomenclature is an internationally standardized system of names and numbers to classify traded products.
The Harmonized System is used by the Standards Organisation of Nigeria as a mechanism for the identification, modification, and implementation of regulatory control over all products. The Nigeria Customs Service also uses it to implement duties and taxes on products, and for gathering statistics.
