The trans Atlantic trade system had three parts that included

The trade proceeded in three steps. The ships left Western Europe for Africa loaded with goods which were to be exchanged for slaves. Upon their arrival in Africa the captains traded their merchandise for captive slaves. Weapons and gun powder were the most important commodities but textiles, pearls and other manufactured goods, as well as rum, were also in high demand. The exchange could last from one week to several months. The second step was the crossing of the Atlantic. Africans were transported to America to be sold throughout the continent. The third step connected America to Europe. The slave traders brought back mostly agricultural products, produced by the slaves. The main product was sugar, followed by cotton, coffee, tobacco and rice.
