BASF SE has detected quality fluctuations in the production of TDI in Ludwigshafen. Deliveries of TDI from Ludwigshafen produced between August 25 and September 29, 2017, contain a significantly higher concentration of dichlorobenzene. This is due to a technical defect in the production, the cause is currently being eliminated.
BASF has informed about 50 affected customers and stopped delivering the product. None of the affected material has been delivered to Asia. The quality fluctuation does not affect any production plants in Asia, and no related issues have been detected.
Of the 7,500 tonnes of TDI, which have a higher dichlorobenzene value, about two-thirds are not yet further processed and are being withdrawn by BASF.
BASF is in close contact with its customers for already processed products. A team of around 75 specialists, for example, assists customers in testing DCB concentrations to avoid any hazard.
