Plain-English explanation
HTS 9903.80.43 is a Chapter 99 steel derivative tariff modification under Section 232 Steel Exclusion. For a qualifying entry during this provision's effective period, the published rate notation is free; the source instructions determine how that notation relates to the underlying base duty. Its published country scope lists all countries, subject to any carve-outs in parallel provisions or the source text. Expired for entries on or after 2025-03-12. Tandom maps 6 base HTS codes to this provision for catalog screening; a dated calculator scenario determines whether it applies.
Historical or scheduled rate mechanics
This catalog record does not establish an additive rate relationship, so the page preserves the published notation without adding it to the base rate. Expired for entries on or after 2025-03-12. The calculator checks the selected entry date and shipment facts before including any Chapter 99 provision.

Authoritative scope text from the U.S. Harmonized Tariff Schedule
Bars and rods, hot-rolled, in irregularly wound coils, of stainless steel, provided for in heading 7221.00.00 (except for statistical reporting numbers 7221.00.0005, 7221.00.0045 and 7221.00.0075)
How to use this provision
Filing mechanics during the provision's effective period
Chapter 99 provision 9903.80.43 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 9903.80.43 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 7221.00.00.05 (of high-nickel alloy steel) from a country in the published scope and all product conditions are met. The published rate notation is Free and the base HTSUS rate is Free. 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. Expired for entries on or after 2025-03-12.
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.
