OSLO, June 6 (Reuters) - The export of fertilisers from Qatari producer Qafco is unaffected by a regional diplomatic row that has cut off other commodity shipments, Norway's Yara YAR.OL said on Tuesday.

Yara has a 25-percent stake in Qafco while state-controlled Industries Qatar IQCD.QA owns the rest.

"We have no logistics problems. Production from that facility is shipped from a dedicated port (in Qatar)," said a Yara spokesman.

Yara's share of Qafco's production amounted to 1 million tonnes of ammonia and 1.5 million tonnes urea fertiliser, he added.

Qatar is the world's fourth largest producer of urea, Qafco said.
