# §7671o. Transfers among Parties to Montreal Protocol

- (a) **In general—** Consistent with the [Montreal Protocol](/usc/42/7671.md?p=9), the United States may engage in transfers with other Parties to [the Protocol](/usc/42/7671.md?p=9) under the following conditions:
  - (1) The United States may transfer [production](/usc/42/7671.md?p=11) allowances to another Party if, at the time of such transfer, the [Administrator](/usc/42/7602.md?p=a) establishes revised [production](/usc/42/7671.md?p=11) limits for the United States such that the aggregate national United States [production](/usc/42/7671.md?p=11) permitted under the revised [production](/usc/42/7671.md?p=11) limits equals the lesser of (A) the maximum [production](/usc/42/7671.md?p=11) level permitted for the substance or substances concerned in the transfer year under [the Protocol](/usc/42/7671.md?p=9) minus the [production](/usc/42/7671.md?p=11) allowances transferred, (B) the maximum [production](/usc/42/7671.md?p=11) level permitted for the substance or substances concerned in the transfer year under applicable domestic law minus the [production](/usc/42/7671.md?p=11) allowances transferred, or (C) the average of the actual national [production](/usc/42/7671.md?p=11) level of the substance or substances concerned for the 3 years prior to the transfer minus the [production](/usc/42/7671.md?p=11) allowances transferred.
  - (2) The United States may acquire [production](/usc/42/7671.md?p=11) allowances from another Party if, at the time of such transfer, the [Administrator](/usc/42/7602.md?p=a) finds that the other Party has revised its domestic [production](/usc/42/7671.md?p=11) limits in the same manner as provided with respect to transfers by the United States in this subsection.
- (b) **Effect of transfers on production limits—** The [Administrator](/usc/42/7602.md?p=a) is authorized to reduce the [production](/usc/42/7671.md?p=11) limits established under this chapter as required as a prerequisite to transfers under [paragraph (1)](#a-1) of subsection (a) or to increase [production](/usc/42/7671.md?p=11) limits established under this chapter to reflect [production](/usc/42/7671.md?p=11) allowances acquired under a transfer under [paragraph (2)](#a-2) of subsection (a).
- (c) **Regulations—** The [Administrator](/usc/42/7602.md?p=a) shall promulgate, within 2 years after November 15, 1990, regulations to implement this section.
- (d) **“Applicable domestic law” defined—** In the case of the United States, the term “applicable domestic law” means this chapter.
