National Urethane Industries has brought a duty increase application on Polyurethane Prepolymers, classifiable under tariff subheading 3909.50, from zero to 10%, by way of creating an additional 8-digit tariff subheading under tariff heading 39.09, which reads as follows: “Polyurethane prepolymers with an NCO percentage of less than 20 per cent“. The reasons given for the duty increase are that these imports are causing injury to the domestic producers, particularly because “certain foreign companies are receiving subsidies from their governments in one way or the other, which is difficult to prove.”  The difficulty in proving these subsidies is presumably the reason why something like a countervailing action was not attempted. As can be seen there has been a 35% increase in the volume being imported in the last 3 years, accompanied by a 5.5% drop in price in the last 12 months, so there would appear to be some pressure being felt. Interested parties have until 18 September 2015 to respond
