Product classification
HS code for Vacuum flask: 9617.00
Vacuum flasks and other vacuum vessels, complete with cases, parts thereof other than glass inners.
Classification of vacuum flask under HS 9617.00
Vacuum flasks and other vacuum vessels are classified under HS code 9617.00. This code is unique because it covers the complete assembly, including the insulating vessel and the protective outer case. The defining characteristic is the vacuum insulation technology used to maintain the temperature of liquids. This heading also includes parts of these vessels, such as caps and carafes, but explicitly excludes glass inners (which are classified under 7020). The classification is straightforward under GRI 1, as the heading text specifically names vacuum flasks. The construction typically involves a double-walled container with the air evacuated from the space between the walls to prevent heat transfer by conduction or convection. Whether the outer casing is made of plastic, stainless steel, or aluminum, the product remains under 9617.00 as long as it utilizes a vacuum for insulation. This heading is part of Chapter 96, which covers miscellaneous manufactured articles, reflecting the fact that these items are finished consumer goods rather than simple kitchenware.

Codes often confused with 9617.00
Common mistake. Vacuum flasks are frequently misclassified under 7323.93 (stainless steel table/kitchenware) or 3924.10 (plastic kitchenware). However, if the item features vacuum insulation, 9617.00 takes precedence as the more specific heading. Another common error is classifying the glass inner vessel under 9617.00; glass inners for vacuum flasks are specifically directed to HS code 7020.00 by the Chapter 96 notes.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
