A word of counsel

The most common error on this tariff line is filing the bill of entry without the Chapter 32 mandatory qualifiers, treating them as optional supplementary data rather than a hard pre-clearance requirement. A declaration deficient in the paragraph 4.1 and 4.2 qualifiers will be held at the customs station pending amendment, attracting demurrage and ground rent; the circular does not provide a post-filing rectification window at the port gate.
