Can prepaid and add freight be EXW terms?

Yes, prepaid and add freight can be used under EXW (Ex Works) terms, but it is not typical. In EXW, the seller's responsibility ends when the goods are made available for pickup at their premises, and the buyer assumes all costs and risks from that point onward. If the buyer chooses to have freight prepaid and added, they would need to arrange and pay for transportation while still taking responsibility for the goods once they leave the seller's location.
