The term “imported taxable product” means any product (other than an ozone-depleting chemical) entered into the United States for consumption, use, or warehousing if any ozone-depleting chemical was used as material in the manufacture or production of such product.
The term “imported taxable product” shall not include any product specified in regulations prescribed by the Secretary as using a de minimis amount of ozone-depleting chemicals as materials in the manufacture or production thereof. The preceding sentence shall not apply to any product in which any ozone-depleting chemical (other than methyl chloroform) is used for purposes of refrigeration or air conditioning, creating an aerosol or foam, or manufacturing electronic components.
No tax shall be imposed by section 4681 on any ozone-depleting chemical which is diverted or recovered in the United States as part of a recycling process (and not as part of the original manufacturing or production process), or on any recycled Halon-1301 or recycled Halon-2402 imported from any country which is a signatory to the Montreal Protocol on Substances that Deplete the Ozone Layer.
Except as provided in subparagraph (B), rules similar to the rules of section 4662(e) (other than section 4662(e)(2)(A)(ii)(II)) shall apply for purposes of this subchapter.
A person’s 1986 export percentage is the percentage equal to the ozone-depletion factor adjusted pounds of ozone-depleting chemicals manufactured or produced by such person during 1986 which were exported during 1986, divided by the ozone-depletion factor adjusted pounds of all ozone-depleting chemicals manufactured or produced by such person during 1986. The percentage determined under the preceding sentence shall be computed by taking into account the sum of such person’s direct 1986 exports (as determined by the Environmental Protection Agency) and such person’s indirect 1986 exports (as allocated to such person by such Agency in determining such person’s consumption and production rights for ozone-depleting chemicals).
Subparagraph (B) shall be applied separately with respect to newly listed chemicals and other chemicals.
The term “importer” means the person entering the article for consumption, use, or warehousing.
In the case of a fraction of a pound, the tax imposed by this subchapter shall be the same fraction of the amount of such tax imposed on a whole pound.
The provisions of subsections (a)(3) and (b)(3) of section 7652 shall not apply to any tax imposed by this subchapter.
If any substance on which tax was paid under this subchapter is used by any person as a propellant in metered-dose inhalers, credit or refund without interest shall be allowed to such person in an amount equal to the tax so paid. Amounts payable under the preceding sentence with respect to uses during the taxable year shall be treated as described in section 34(a) for such year unless claim thereof has been timely filed under this paragraph.
If, on any tax-increase date, any ozone-depleting chemical is held by any person (other than the manufacturer, producer, or importer thereof) for sale or for use in further manufacture, there is hereby imposed a floor stocks tax.
For purposes of this paragraph, the term “tax-increase date” means January 1 of any calendar year.
The taxes imposed by this subsection on January 1 of any calendar year shall be paid on or before June 30 of such year.
All other provisions of law, including penalties, applicable with respect to the taxes imposed by section 4681 shall apply to the floor stocks taxes imposed by this subsection.
