Heerlen, The Netherlands-DSM Agro, a unit of Royal DSM NV, reports that problems at one of its ammonia plants in the Netherlands that began in June may take into October to repair. The production interruption was originally estimated to last only a few weeks. DSM said the incident was unexpected, but once repairs are complete the plant will be back at full production. While the damage to assets is limited, the business loss for DSM Agro, for which ammonia is the primary raw material, could run into several tens of millions. However, the company said that due to insurance, the one-time impact to the company is expected to be between E25-30 million, most of which will occur in the third quarter. DSM said considering the current positive business climate for both DSM and DSM Agro, this interruption in production is no reason for DSM to lower the outlook it has given for the full year.
