How to use this provision
When and how this overlay shows up at entry
Chapter 99 provision 9903.27.14 is a tariff modification — it doesn't classify a product on its own. When a base 10-digit HTS code falls within this provision's scope and a shipment matches the country and date conditions, the broker declares the base code at entry, then references 9903.27.14 on a separate line so its rate stacks on top.
Worked example
How this overlay applies to a real covered code
Imagine an importer files a $10,000.00 shipment of 7601.20.90.30 (aluminum vanadium master alloy) from a country in scope. The overlay rate of 100% stacks on top of the base HTSUS rate of Free.
