Dilmun (i.e Bahrain) was referenced by Mesopotamian Kings as the exporter of teak, Indian cedar, and probably rosewood. This was all back in the mid 3rd millennium B.C. .
Frankincense perfumes are also famous to Oman via the Dhofar region, but Dilmun was a famous for trade in the stuff. Myrrh has been found (probably from Baluchistan) taken from Dilmun by the Assyrians in the 7th century BC, but deposits of it may exist on the Ras Al Jinz finds.
Relating to the perfume export business, through which Magan often acted as a centre, soft-stone containers and dishes have been found to originate, which, Potts (2017) surmises were mostly for the holding or perfumes and oils and incense gums and resins. These have been distributed as far afield in the 3rd mill BC as Palmyra in Syria, Iran, Pakistan, Iraq, and Uzbekistan.
Dates were also traded, as the letter from the Queen of Dilmun to the Queen of Lagash illustrates, and although Iraq would have been no stranger to date cultivation, maybe ancient men and women preferred variety in their produce as much as modern day Omanis do, when it comes to dates?:).
Potts (2017) surmises that the most common trade Magan and Dilmun made with Mesopotamia was for clothing and textiles.
