In a statement released this week, the Portugal-based papermaker said it will increase paper prices across all its products and target markets as of 18 January next year.

Due to “the continuous increase in the key production costs”, Navigator will raise prices for its clients in Europe by increments ranging from 4% to 6%. Its portfolio, sold across five continents, includes paper brands such as Navigator, Pioneer, Inacopia and Discovery.

Further price increases were announced for Navigator’s folio and reels by €100/ton (£88.4) in the Middle East, Africa and Turkey due to low profitability.

A spokesperson was unavailable to comment further at the time of writing.

In late October, German papermaker Zanders announced it will increase prices for all deliveries from 1 January, with the amounts discussed on an individual basis with customers.

Prices for chemical, energy and pulp being at an “all-time high” were attributed as the main causes by Zanders sales director John Tucker. He said the strategic increase was hoped to “ensure a stable future for the company”.
