WTO members/observers use the TBT Committee to discuss specific trade concerns (STCs) — specific laws, regulations or procedures that affect their trade, usually in response to notifications. Essentially, members raise STCs to find out more about the scope and implementation of each other's regulations in light of the core TBT obligations. The discussion is mostly about measures in the pipeline, but can also be about the implementation of existing measures. To date, more than 400 “STCs” have been raised which can be accessed through the TBT Information Management System TBT IMS — the database of WTO information on TBT notifications, specific trade concerns, enquiry points, etc.
