The force majeure on chlorine and caustic soda at the French site had been put in place at the end of June, resulting from some downtime caused by a labour dispute.
Toluene diisocyanate (TDI) production at Le Pont-de-Claix had also been impacted by the labour dispute, but no force majeure had been declared on this product.
Operations restart at the production site in France began in July, with a gradual ramp-up implemented, following the end of the labour dispute.
The TDI facility at Le Pont-de-Claix has returned to normal output, an isocyanate company source confirmed on Tuesday, although it added that supply remains tight and that it is in the process of rebuilding stocks.
Planned maintenance work had also taken place at Le Pont-de-Claix operations, prior to the labour dispute.
The TDI facility at Le Pont-de-Claix has the capacity to produce 125,000 tonnes/year, as previously confirmed by a company source. Details on the nameplate capacity for chlorine and caustic soda unit at Le-Pont- de Claix were not available at the time of writing.
