A word of counsel

The most common error on this tariff line is treating the CDSCO drug-registration pathway as the sole compliance obligation and overlooking the CWC post-import notification requirement. Failure to notify the National Authority CWC, the Department of Chemicals and Petrochemicals, and DGFT within 30 days of each consignment's import is an independent breach under the ITC (HS) Schedule-2 chemical regime — it does not become compliant retrospectively by filing a late bill-of-entry copy, and the 30-day window runs from the date of import, not the date of out-of-charge.
