Why is there a gap in the top of the tin of formula?

Formula powders are packed by weight, not volume, powder tends to settle and compress over time, so at the time of filling, the product level normally sits higher compared to where it would be in 3 or 4 or 6 months later. Our state-of-the-art equipment weighs every single tin to a high level of accuracy.
All our products are carefully weighed during our manufacturing process. It’s very normal for the our formula powder to settle during transport and storage. Please rest assure that the weighted amount is as we have stated on the packaging.
