These certifications are in full or partially required to be compliant in the below listed target countries, but might require additional local approvals & paperwork:

HICS will not perform a formal patent / license check for every component or combination of components for every region/country indicated. For a defined list of (key) components the supplier of the component will be asked by HICS to verify the country list against the applicable components and provide answers in writing to HICS. HICS will build a file with the replies of the individual suppliers. HICS is not liable for false answers provided by components suppliers. HICS is not liable for formal usage right approval for every country/region since not all licenses / patents / IP rights on components or the application of combinations of components, technologies can be overseen for every region.
