One or more required product facts or contemporaneous policy records are unresolved. Review the critical warnings below before relying on this scenario.
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).
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.
Section 232 pharmaceutical declaration
Patented Annex I products require a company tranche and treatment. Company adjustments require written Commerce approval; selecting an option is an importer attestation, not an approval lookup.
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.
