What is Generalized Scheme of Preferences (GSP)?

Generalized Scheme of Preferences (GSP) provides developing country exporters possibility to pay less/ no duty on their plywood and hardboard exports to the EU. In this way countries receive access to EU markets. On January, 01, 2014 the new GSP preferences under EU Regulation 978/2012 started to apply.
More than 80 countries and territories are no longer beneficiaries of GSP. As a result, plywood and hardboard products originating in these countries will no longer benefit from a preferential trade scheme upon importation into the EU. As the list of removed countries contains some major economies, products originating in these countries will be affected by the new regime. Russian and Belarusian plywood and hardboards as the goods originated in the mentioned countries are excluded from the GSP regime

Classification, packaging, labelling and marking of the material itself are significant. For dangerous goods transportation UN approved hardboard boxes and plywood boxes, certified fiberboard boxes for lithium batteries, packaging for infectious and biological substances and certified polyethylene bags. Also should be all required transport documentation corresponding to the regulations. Interior birch or birch/alder plywood of low grades is usually used for packaging production
