In the Parcel Packing > Parcel Adjustments tab you can set the default weight and measurements for parcels (27). These values are required to quote the shipping rates and will be applied by default to products without weight or dimensions set.
You can also set an additional weight (in % or fixed amount) to add to all your parcels (28). This is useful if you include some gadgets, flyers, instructions, promotional materials, etc., in all your parcels.
