Export restriction on guar gum: exports allowed only with health certificate and PCP-free analytical report. Exports of refined, treated or pulverized guar gum to the European Union for human or animal consumption are allowed only if accompanied by a Health Certificate from the authorized representative (SHEFEXIL) and the original analytical report from Vimta Labs certifying that samples taken by the authorized representative contain no Penta Chlorophenol (PCP) in any proportion, replacing the earlier permitted trace tolerance.
