How to use this provision
When and how this overlay shows up at entry
Chapter 99 provision 9903.80.29 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 9903.80.29 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 7220.12.10.00 (of a width of 300 mm or more) from a country in scope. The overlay rate of Free stacks on top of the base HTSUS rate of Free.
The base rate or overlay rate isn't a clean ad-valorem percentage, so the math stays narrative here. Use the calculator for a precise stack.
