I bought 175 g pack of salami which had 162 g of salami as well.

    It’s a 2% difference. The cutting and packaging is done (most probably) by machines. I have clinically diagnosed OCD, and I wouldn’t care about 8g of missing pasta… How much do you leave on the plate/in the pot/throw away? :)

    Otoh, hitting exactly 410g (assuming the scale is calibrated, and you have the same temperature, air moisture and altitude as the factory), is very difficult. They could adjust their machines so the variation hangs a bit more towards the customer, but for them, 2% x millions of boxes = profit.

      Most of our packaging machines require < 1%, target <0.5% variance (both ways). Honestly in practice, over a whole batch the total variance is extremely tiny.

      Add to this story the accuracy of a household, not-calibrated scale? Yeah I’d say this seems OK.

        What do you make?

        Tolerances for food items depend a lot on item size, shape, and irregularity.

          I mean… that’s a good point. I only make bulk materials, like 1 ton supersaks, and we tend to OVERfill so customers don’t complain, with the target still being close to zero for a whole batch.
