Use ePing to review proposed technical regulations and conformity assessment procedures 

The ePing SPS&TBT platform (, or “ePing”, provides access to notifications made by WTO Members under the Agreements on Sanitary and Phytosanitary Measures (SPS) and Technical Barriers to Trade (TBT), distributed by the WTO from January 16, 1995 to present.  ePing is available to all stakeholders free of charge and does not require registration unless the user wishes to receive customized e-mail alerts.  Use it to browse notifications on past as well as new draft and updated product regulations, food safety and animal and plant health standards and regulations, find information on trade concerns discussed in the WTO SPS and TBT Committees, locate information on SPS/TBT Enquiry Points and notification authorities, and to follow and review current and past notifications concerning regulatory actions on products, packaging, labeling, food safety and animal and plant health measures in markets of interest.
