(1) The authorised packer shall have suitable arrangements for filtration, blending and storage of essential oils;
(2) If the packer proposes to handle more than one essential oil in the same premises, there should be detail oil in the same premises, there should be adequate arrangements to avoid mixing of different oils;
(3) The packer shall either set up his own laboratory manned by qualified chemist duly approved by the Agricultural Marketing Adviser or an officer authorised in this regard for testing the quality of essential oils, or have access to the State Grading Laboratory, Co-operative or Association Laboratory or Private Commercial Laboratory approved for purpose of grading and marking of essential oils by the Agricultural Marketing Adviser or an officer authorised by him in this regard.
