ISLAMABAD - Pakistan Jute Mills Association (PJMA) has requested the government to increase tariff on import of jute yarn and jute twines in order to protect the domestic industry. “The PJMA has requested National Tariff Commission (NTC) to enhance present customs duty of 10 per cent to 25 per cent on import of jute yarn and jute twines “, said a statement issued here by the NTC on Tuesday. The association made its demands on the grounds that yarns and twines are made from both jute and sisal plants and are of same nature and use for similar purposes.
