While getting ready for departure; the First Officer brought to my attention the fact that he smelled some odor coming from the Dangerous Goods pallet in position 1.  I went to inspect the pallet myself after the Hazmat Specialist was notified and was present. I confirmed the First Officer's findings and smelled the odor as well. The rest of the crew smelled it (second First Officer); and agreed on it too. The Hazmat spill specialist in ZZZ was contacted via phone; and we agreed with the senior specialist and followed her directives for removing the pallet for verification;  and accountability. The process to accomplish such a task exceeded the time available for departure; and leaving the pallet at the station for processing was the preferred option to avoid further delays. A new Weight and Balance was calculated and received. No further incidents.
B777 Captain reported an undefined odor emanating from Dangerous Goods pallet. After conferring with the DG specialist the pallet was removed; flight crew completed an uneventful flight.
