Notwithstanding the preceding sentence, a retailer engaging in convention and trade show activities, as described in Section 513(d)(3)(A) of the Internal Revenue Code, is a “retailer engaged in business in this state,” and is liable for collection of the applicable use tax, with respect to any sale of tangible personal property occurring at the convention and trade show activities and with respect to any sale of tangible personal property made pursuant to an order taken at or during those convention and trade show activities.(f) Any limitations created by this section upon the definition of “retailer engaged in business in this state” shall apply only for purposes of tax liability under this code. Nothing in this section is intended to affect or limit, in any way, civil liability or jurisdiction under Section 410.10 of the Code of Civil Procedure.
