A word of counsel

The most common error on this tariff line is treating the drug-documentation set as universally mandatory for all nitrite imports. The CDSCO drug-registration and import-licence documents (101dc1, 9111dc) are triggered only when the nitrite is being imported as a pharmaceutical substance; industrial or reagent-grade nitrites not classified as drugs do not require those documents but still attract the Chapter 28 mandatory qualifiers under CBIC Circular 23/2023-Cus and the Public Liability Insurance overlay when hazardous-substance quantity thresholds are met.
