A word of counsel

The most common error on this tariff line is treating the CDSCO import licence as the sole compliance gate and overlooking the CWC Category 1B post-import notification obligation. The 30-day notification window to the National Authority CWC, the Department of Chemicals and Petrochemicals, and DGFT — together with submission of the bill of entry to DGFT — is a separate statutory obligation that runs after customs out-of-charge; failure to notify within the window constitutes a CWC-policy breach independent of the import licence validity.
