How to use this provision
When and how this overlay shows up at entry
Chapter 99 provision 9903.81.80 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 9903.81.80 on a separate line so its rate stacks on top.
