Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

UHY LLP (“UHY”) served as USD Partners LP’s (the “Partnership”) independent registered public accounting firm to audit the combined financial statements of the Partnership’s Predecessor for the fiscal year ended December 31, 2013. The Board of Directors of USD Partners GP LLC (“USD Partners GP”), the general partner of the Partnership, selected UHY to serve as the Partnership’s independent registered public accounting firm for the fiscal year ending December 31, 2014. On December 1, 2014, UHY informed the Partnership that effective on that date, its Texas practice had been acquired by BDO USA, LLP (“BDO”), a U.S. professional services firm which provides assurance, tax, financial advisory and consulting services to a wide range of publicly traded and privately held companies, and that all partners and professional employees of UHY’s Texas practice working on matters on behalf of the Partnership had joined BDO. As a result of this transaction, effective December 1, 2014, UHY resigned as the Partnership’s independent registered public accounting firm for the fiscal year ending December 31, 2014.

Subsequently, on December 4, 2014, the Audit Committee of the Board of Directors of USD Partners GP engaged BDO to serve as the Partnership’s independent registered public accounting firm for the fiscal year ending December 31, 2014. Prior to such appointment, neither the Partnership nor its predecessor had consulted with BDO with respect to the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Partnership’s or its Predecessor’s financial statements, or any other matter or reportable events listed in Items 304(a)(2)(i) and (ii) of Regulation S-K.

The audit reports of UHY on the Partnership’s Predecessor combined financial statements for the years ended December 31, 2013 and 2012 did not contain an adverse opinion or disclaimer of opinion, and these statements were not qualified or modified as to uncertainty, audit scope or accounting principles.

During the fiscal years ended December 31, 2013 and 2012, and the subsequent interim periods through December 1, 2014, there were no disagreements with UHY on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreement, had it not been resolved to the satisfaction of UHY, would have caused UHY to make reference thereto in its reports on the financial statements for such periods. During this time, there have been no “reportable events,” as that term is described in Item 304(a)(1)(v) of Regulation S-K.

The Partnership provided UHY with a copy of this Current Report on Form 8-K and requested that UHY furnish it with a letter addressed to the Securities and Exchange Commission stating whether UHY agrees with the above statements. A copy of such letter dated December 2, 2014, is filed as Exhibit 16.1 to this Current Report on Form 8-K.
