US imports of Vacuum flasks and other vacuum vessels, complete

US imports under HTS 9617 at a glance

Between March and July 2026, US importers entered $719 million of vacuum flasks and other vacuum vessels, complete under HTS heading 9617, from 26 of the 55 origin countries covered here and across 4 ten-digit tariff lines — roughly $144 million a month of customs value under a single four-digit heading.

Heading 9617 sits in chapter 96, miscellaneous manufactured articles, so anything classified here shares a duty structure with the rest of that chapter.

Who exports vacuum flasks and other vacuum vessels, complete to the United States

China supplies 75.7% of everything entered under this heading — $544 million over the five months — which makes this a single-source market in practice. Thailand is a distant second at 10.3%, then Vietnam at 10.2%. 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.

Asian origins supply 99.9% of the heading, led by China, Thailand, Vietnam and Malaysia. That means ocean transit from Asian base ports and, for most of these countries, no free-trade-agreement relief — so the tariff line you classify into carries the full cost.

What importers actually paid in duty

Almost everything under this heading is dutiable: 100% of entered value carried duty, and CBP collected $122 million over the five months. The effective rate on dutiable value was 17%, which works out to $17.00 of duty per $100 of goods. There is no meaningful duty-free channel here — classification and origin are the only levers.

Duty treatment is fairly uniform across origins here: the countries with real volume all land within a narrow band of $16.92–$17.02 per $100 of goods. Where that happens, switching origin does little for the duty bill, and savings have to come from classification, valuation or freight.

The 10-digit lines under heading 9617

4 ten-digit lines carried trade under this heading in the period. The largest, 9617.00.10.00, took 78.4% of the heading at $564 million. 9617.00.30.00, 9617.00.40.00 and 9617.00.60.00 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 $17.00 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: China (9617.00.10), Thailand (9617.00.10) and Vietnam (9617.00.10). 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

Classify first, confirm origin second, quote freight third. A heading like 9617 rewards that order, because the duty differences between lines and between origins are usually larger than the freight differences on the same lane. Airlift USA handles the freight and coordinates classification and entry through our licensed broker network.
