HS Code for Thermos

A thermos, or vacuum flask, is classified under HS code 9617.00. This heading is part of Chapter 96, which encompasses miscellaneous manufactured articles. The specific description for 9617.00 includes vacuum flasks and other vacuum vessels, complete with cases, as well as parts thereof other than glass inners. The classification is determined by the physical construction of the vessel, which must feature a double-wall design with a vacuum-sealed space between the walls to prevent heat transfer by conduction or convection. This heading is unique because it covers the finished article regardless of the material of the outer shell (whether plastic, stainless steel, or aluminum). The General Rules of Interpretation (GRI) 1 dictate that the terms of the heading are the primary authority; since 9617.00 explicitly names vacuum flasks, it takes precedence over headings based on the component material (like 7323 for steel or 3924 for plastic). It is important to note that this code applies to the complete assembly. If a vacuum flask is imported without its outer case (just the glass inner), it is excluded from this heading and must be classified according to its material, typically under heading 7020 as an article of glass.

Products Included

Common Misclassification

Thermoses are frequently misclassified under 7323.93 (table or kitchenware of stainless steel) or 3924.10 (plastic tableware). While many thermoses are made of these materials, the specific function of vacuum insulation moves them to 9617.00. Another common error involves glass inners; if imported alone, they should be classified under 7020.00, but many importers mistakenly use 9617.00 for the parts, forgetting the exclusion for glass inners in the heading text.

FAQ

What is the HS code for thermos?

The HS code for a complete thermos or vacuum flask is 9617.00.

Does this code cover insulated mugs without a vacuum?

No, if the mug uses foam insulation or simple double-wall air insulation without a vacuum, it is classified by its material (e.g., 7323 for steel or 3924 for plastic).
