Plain-English explanation
HTS 9903.82.05 is a Chapter 99 tariff modification under Section 232. For a qualifying entry during this provision's effective period, the published rate notation is 15%; the source instructions determine how that notation relates to the underlying base duty. Its published country scope lists GB. Active for entries on or after 2026-04-06; no expiration is on file. Tandom maps 685 base HTS codes to this provision for catalog screening; a dated calculator scenario determines whether it applies.
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 2026-04-06; 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 9903.82.05 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 9903.82.05 on a separate line.

Worked example
Published notation shown without assuming an additive rate
For an illustrative $10,000.00 entry during a period when this provision is in effect, assume an importer files 7321.11.10.30 (stoves or ranges) from a country in the published scope and all product conditions are met. The published rate notation is 15% and the base HTSUS rate is 5.7%. The catalog does not carry a structured additive relationship for this provision, so this example does not add the displayed percentage to the base rate. Active for entries on or after 2026-04-06; no expiration is on file.
No numeric total is shown because a published percentage alone does not establish whether the provision is additive, total, or otherwise conditional. Use the calculator for a dated scenario.
