A word of counsel

The most frequent compliance failure on this tariff line is treating strontium carbonate as a plain industrial chemical and omitting the Chapter 28 mandatory qualifiers from the import declaration. CBIC Circular 23/2023-Cus applies to all Chapter 28 commodities without exception — including industrial-grade strontium carbonate — and a declaration filed without the stipulated qualifiers from 15 October 2023 onward faces detention and ground rent while the importer files a revised entry.
