Plain-English explanation
HTS 9903.05.01 is a Chapter 99 tariff modification under Section 301 Brazil. For a qualifying entry during this provision's effective period, the published rate notation is the duty provided in the applicable subheading + 25%; the source instructions determine how that notation relates to the underlying base duty. Its published country scope lists BR. Active for entries on or after 2026-07-22; no expiration is on file.
Illustrative rate mechanics for a qualifying entry
This catalog record does not establish an additive rate relationship, so the page preserves the published notation without adding it to the base rate. Active for entries on or after 2026-07-22; no expiration is on file. The calculator checks the selected entry date and shipment facts before including any Chapter 99 provision.

How to use this provision
Filing mechanics during the provision's effective period
Chapter 99 provision 9903.05.01 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 9903.05.01 on a separate line.
