HTS heading 0603 covers cut flowers and flower buds, entering the United States at a 6.4% MFN duty rate. Fresh cut flowers and buds suitable for bouquets or ornamental purposes. Roses and carnations dominate imports. Beyond the base MFN duty, goods under this heading from most non-EU origins add the Section 301 forced-labor tariff (10% standard, 12.5% for the ~28-economy forced-labor tier such as China, Vietnam, and Thailand), which took over from the expired Section 122 rate on July 24, 2026. EU-origin goods are capped at the 15% all-inclusive EU-US deal ceiling instead. Worked example: a $10,000 shipment under HTS 0603 owes about $640 in MFN duty (6.4%); adding the 10% base forced-labor surcharge brings it to roughly $1,640 from a standard-tier origin, or about $1,890 from a 12.5%-tier origin such as China.
