How to use this provision
Filing mechanics during the provision's effective period
Chapter 99 provision 9903.17.31 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 during its effective period and a shipment matches the country and date conditions, the broker declares the base code at entry and follows the source instructions for reporting 9903.17.31 on a separate line.
