Registration Certificate requirement for IPA imports imposes country-wise quantitative restrictions and quarterly allocation controls. The Public Notice imposes country-wise quantitative restrictions on Isopropyl Alcohol imports for 2023-24 and prescribes online application procedures for Registration Certificates (RCs) valid to year-end, with a filing deadline of 20 April 2023 and disclosure of past imports. RC utilization is subject to quarterly review and adjustment: quarterly imports cannot exceed that quarter plus the next; over-utilisation is deducted from the following quarter while unutilised QR rolls forward; exhausted country-specific QR may be met from residual allocations of other countries. The Directorate may cap any single RC and modify allocation modalities.
