The Portuguese papermaker said the new European prices will be effective for all deliveries from 1 March onwards. It had previously implemented UWF increases in early January.

“Reflecting the volatility of the current market conditions, Navigator will revise the situation continuously and price lists will have a maximum validity of two months,” the company stated.

Navigator added it would not be able to keep its usual four-week pre-notice for price list changes.

“This decision was taken due to [unprecedented] times that the market is experiencing with a continuous cost increase in all relevant manufacturing inputs, as well as logistics, several abnormal disruptions that keep limiting supply and unparallel order book in the industry.”

Navigator said it believes this “exceptional measure” is imperative to support the long-term sustainability of its business model and of the overall supply chain.

“The company will continue working to reinforce its partnerships with its clients, strengthening its value proposition across several dimensions, appreciating the support provided by its large and very loyal customer base,” the business added.

Navigator brands include Discovery, Inacopia, Inaset, Pioneer, Soporset and Target and the eponymous Navigator.
