    (e) A sale or transfer of machinery and equipment used primarily in the process of the manufacturing or assembling, either in an existing, an expanded or a new manufacturing facility, of tangible personal property for wholesale or retail sale or lease, whether such sale or lease is made directly by the manufacturer or by some other person, whether the materials used in the process are owned by the manufacturer or some other person, or whether such sale or lease is made apart from or as an incident to the seller's engaging in a service occupation and the applicable tax is a Service Occupation Tax or Service Use Tax, rather than Retailers' Occupation Tax or Use Tax.

The purchase of such tangible personal property by the serviceman shall be subject to tax under the Retailers' Occupation Tax Act and the Use Tax Act. However, if a primary serviceman who has made the election described in this paragraph subcontracts service work to a secondary serviceman who has also made the election described in this paragraph, the primary serviceman does not incur a Use Tax liability if the secondary serviceman (i) has paid or will pay Use Tax on his or her cost price of any tangible personal property transferred to the primary serviceman and (ii) certifies that fact in writing to the primary serviceman.

The purchaser of such machinery and equipment and tools without an active resale registration number shall furnish to the seller a certificate of exemption for each transaction stating facts establishing the exemption for that transaction, which certificate shall be available to the Department for inspection or audit.
    Except as provided in Section 2d of this Act, the rolling stock exemption applies to rolling stock used by an interstate carrier for hire, even just between points in Illinois, if such rolling stock transports, for hire, persons whose journeys or property whose shipments originate or terminate outside Illinois.
    Any informal rulings, opinions or letters issued by the Department in response to an inquiry or request for any opinion from any person regarding the coverage and applicability of exemption (e) to specific devices shall be published, maintained as a public record, and made available for public inspection and copying. If the informal ruling, opinion or letter contains trade secrets or other confidential information, where possible the Department shall delete such information prior to publication. Whenever such informal rulings, opinions, or letters contain any policy of general applicability, the Department shall formulate and adopt such policy as a rule in accordance with the provisions of the Illinois Administrative Procedure Act.
