Dear Friend ,
Your understanding is right and now there is no requirement of getting re-warehousing certificate from the officer.
If your supplier, insists or requesting for Signed ARE-3A, then you may send with self signature.
Further, Notification No. 44/2016-Cus dated 29.07.2016 issued withdrawing warehousing procedure for imported materials under EOU Scheme ( NF 52/2003-Cus). In this context, board also issued circular No.35/2016-Cus Dated 29.07.2016 . Vide point NO. 6 and 7 of the circular, the Board clarified as below for your ready reference.
In view of the warehousing procedures having been dispensed with for these units, the system of sending re-warehousing certificates to the customs station of import shall also stand dispensed w.e.f 13th August 2016.
