Relations with HS

The WCO Guide for Technical Update of Preferential Rules of Origin provides practical information on how to conduct a technical update of Rules of Origin in relation to changes in the Harmonized System. 

The Guide has been prepared for Members who wish to update their existing Rules of Origin based on an older edition of the HS to ones based on the latest edition of the HS. 

The technically updated Rules of Origin may replace the existing ones or be used as a basis for reviewing and amending the former, according to the procedures set out in the applicable Free Trade Agreements (FTA). 

Carrying out a technical update may also help Members to identify items requiring adjustment to the product specific rules of FTAs already in place.
