A word of counsel

The most common error on this tariff line is importing strontium sulphate as a general inorganic chemical without verifying whether the specific end-use formulation or purity grade triggers the drug-documentation overlay. If the consignment is routed through a PGA-facilitated bill without the five drug-related documents uploaded in e-Sanchit, the proper officer will withhold out-of-charge pending rectification — generating detention and demurrage that cannot be resolved retrospectively at the port.
