A word of counsel

The most common error on this tariff line is filing the bill of entry without completing the Chapter 28 mandatory qualifiers under CBIC Circular 23/2023-CUS, treating silicon tetrachloride as a routine inorganic chemical that warrants no special declaration. The qualifier obligation applies at the line level, not only at the chapter heading — an incomplete entry triggers amendment proceedings and port detention before out-of-charge can be granted.
