I just checked mine, which was made in France & packaged in Toronto. It doesn't say kosher or pareve like most foods, or have the more common Circle-K symbol, but it does have the Star-K and Circle-U kosher symbols ... on the last side of the box I checked and they are very tiny.

I suspect tallow or some sort of oil is used to make parchment non-sticky, but silicone is probably used instead to achieve nonstickiness (unless it is more expensive). Curiously this French parchment is more pliable and was half the price of parchment made in North America, despite the shipping. An 80 yr old friend always complained about American parchment being stiff and noisy (like cellophane) and preferred European parchment.
