Trade in the Phoenician World – World History Encyclopedia
Here’s a start LMK if you need more:
Phoenician sea trade can, therefore, be divided into that for its colonies and that with fellow trading civilizations. Consequently, the Phoenicians not only imported what they needed and exported what they themselves cultivated and manufactured but they could also act as middlemen traders transporting goods such as papyrus, textiles, metals, and spices between the many civilizations with whom they had contact. They could thus make enormous gains by selling a commodity with a low value such as oil or pottery for another such as tin or silver which was not itself valued by its producers but could fetch enormous prices elsewhere.
