Apple’s Russian distribution arm, Apple Rus, is suing the customs agency over import duties on the iMac. Apple Rus's claim stems from a customs' decision to introduce a 6% duty on the iMac. Prior to fall of 2013, Apple had declared the iMac under customs code 8471 49, which denotes industrial equipment necessary for knowledge-based economic development (and does not require import duties). Several months ago, however, Apple reregistered the iMac under the category of all-in-one computers and laptops (which stipulates a 6% customs duty). According to Gartner, an information technology research and advisory company, in mid-2013 Apple held 3% of the shrinking Russian PC market, which is dominated by HP (12%) and Lenovo (10%).
