Origin: 🇿🇦 South Africa (ZA) · Unit: kg · Base: MFN Base Rate (General)
Program lapsed 2020-12-31. CBP advises filers to continue flagging SPI "A" on qualifying entries so duties can be refunded if Congress reauthorizes retroactively (H.R. 4276 pending).
Reauthorized through 2026-12-31 by Pub. L. 119-75 (Consolidated Appropriations Act, 2026), retroactive to 2025-09-30. Long-term extension under USTR "AGOA modernization" review per 2026-02-03 statement.
Unilateral preferences are claimed at entry by prefixing the SPI to the HTSUS number. The simulator does not auto-zero the MFN rate for these programs because eligibility depends on article-specific tariff-shift, de minimis, and substantial-transformation rules outside the HS + country pair. Confirm with the CBP reference before filing.
Landed-cost Fee Overlay (MPF + HMF)
Estimate the Merchandise Processing Fee and Harbor Maintenance Fee separately from the ad-valorem duty stack. Fees are charged on entered value, not as a percentage on top of the tariff.
Simulation, not a filing basis. This tool models the ad-valorem duty stack for directional analysis. It does NOT replace the official HTSUS, a licensed customs broker, or Commerce / USTR / CBP rulings. The total does not include antidumping or countervailing duties (AD/CVD), non-ad-valorem specific duty components, preferential FTA rates that require origin qualification, Chapter 98 provisions, Chapter 99 exclusions, or §232 absolute-quota fill status. Rates change frequently. Before entering any commercial shipment, verify the applicable rate in the USITC HTSUS and confirm with CBP or a licensed customs broker.
