US imports of Cut flowers and flower buds of a kind suitable

US imports under HTS 0603 at a glance

Between March and July 2026, US importers entered $711 million of cut flowers and flower buds of a kind suitable under HTS heading 0603, from 33 of the 55 origin countries covered here and across 35 ten-digit tariff lines — roughly $142 million a month of customs value under a single four-digit heading.

The heading belongs to chapter 06, live trees, plants and cut flowers. Classification disputes in this range usually turn on the six-digit subheading, which is where the rates start to diverge.

Who exports cut flowers and flower buds of a kind suitable to the United States

Colombia supplies 77.7% of everything entered under this heading — $553 million over the five months — which makes this a single-source market in practice. Canada is a distant second at 9.1%, then Netherlands at 6.8%. When one origin carries this much of a heading, a tariff action aimed at that country moves the landed cost of the whole category rather than shifting share between suppliers.

Canada and Mexico sit near the top of the table, and the duty numbers reflect it: Canada entered 99.9% of its value free of duty and Mexico entered 99.5% of its value free of duty. Cargo that qualifies under USMCA and is claimed correctly at entry pays nothing; cargo that does not qualify, or that is never claimed, pays the ordinary rate. The certification is the whole difference.

What importers actually paid in duty

Almost everything under this heading is dutiable: 87.8% of entered value carried duty, and CBP collected $67.0 million over the five months. The effective rate on dutiable value was 10.7%, which works out to $9.42 of duty per $100 of goods. There is no meaningful duty-free channel here — classification and origin are the only levers.

The spread between origins is real. Among origins with at least 2% of the heading, Netherlands paid the most duty relative to value — $16.30 per $100 — while Canada paid $0.01. On a $250,000 purchase order that gap is about $41,000 in duty alone, which is worth pricing into a sourcing decision rather than discovering on the entry summary.

The 10-digit lines under heading 0603

35 ten-digit lines carried trade under this heading in the period. The largest, 0603.11.00.50 (other), took 31.1% of the heading at $221 million. 0603.14.00.10, 0603.19.01.45 and 0603.12.70.00 follow. Rates diverge between those lines, so the classification your broker files is worth checking against the goods rather than carried over from the last entry.

What the duty stack looks like

The rate on an entry is not one number. It is a stack: the general (column 1) rate for the 10-digit line, less any trade-agreement preference the goods qualify for, plus whatever additional duties apply to that product and origin, all applied to the customs value declared. The $9.42 per $100 above is what that stack averaged across every entry in this heading — a benchmark, not a quote.

For the origins carrying the most volume, the per-country breakdowns go a level deeper: Colombia (0603.11.00), Netherlands (0603.19.01) and Guatemala (0603.11.00). To price a specific shipment, put your 10-digit code and country of origin into the tariff simulator.

What this means for your next shipment

The numbers above are a starting point, not the answer for a specific shipment: the rate depends on the exact 10-digit line, the origin, and any trade-agreement claim you can substantiate.
