The Portuguese papermaker said the price increase, which is effective on products dispatched from 3 January onwards, includes a rise of the surcharge announced by the company in October, from €50/tonne to €100/tonne.

The business said that since its last communication, where the prior surcharge was accompanied by a price increase of around 8% effective as of 1 November, the industry “has been continuously facing additional variable cost increases, particularly in energy and logistics, that is also leading to increases in the majority of other commodities, such as chemicals and packaging materials”.

“Additionally, The Navigator Company is witnessing a significant increase in demand for its products and brands, which leads to a record of its order book,” the company stated.

It added that, reflecting the volatility of the current market conditions, the surcharge will be revised on a monthly basis and the price list will have a maximum validity of two months.

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

“Navigator understands that these circumstances are extremely challenging and genuinely appreciates the trust of its commercial partners during this challenging period we are all living,” the company said.

Navigator brands include Discovery, Inacopia, Inaset, Pioneer, Soporset and Target and the eponymous Navigator. The group sells its products to 130 countries over five continents.
