With Thunderbolt Express, your service fee is based on both what your parcel is worth and how big or heavy it is. First, we look at your invoice total in ZAR. Then we compare your parcel’s actual weight with its volumetric weight (how much space it takes up).

We always use the higher of the two as the chargeable weight, then apply our internal percentage and minimum fee to give you an all‑inclusive estimate. This covers handling, storage, courier, customs clearance and door‑to‑door delivery in Malawi. Use the calculator below to see a quick estimate before you request your official quote.
