15. MAJOR SUPPLIERS

During the three-month period ended March 31, 2014 and 2013, the Company purchased 89.8% and 83.6% of its raw materials from its top five suppliers, respectively.  As of March 31, 2014 and 2013, amounts due to those suppliers included in accounts payable were $3,988,704 and $3,847,225, respectively. This concentration makes the Company vulnerable to a near-term severe impact, should the relationships be terminated.
