Certified Parev only when 'KLBD Kosher' is inkjetted on the lid. Available from kosher shops. Other wholesalers, such as Costco, also sell the 600g tubs but it is important to check before purchase that each tub has 'KLBD Kosher' on the lid, as old stock in identical tubs and not bearing the KLBD stamp, is Not Kosher. At the present time, we do not recommend purchasing these tubs from online retailers such as Amazon as they may still be selling old, non-kosher stock.
