HTS Codes, Duty Rates & Common Classification Mistakes<\/h3>\n\n\n\n

Importing vacuum insulated tumblers (also known as thermos flasks) into the United States can be confusing due to different materials, constructions, and duty treatments<\/strong>. Choosing the wrong HTS code may result in overpaying duties, shipment delays, or customs audits<\/strong>.<\/p>\n\n\n\n

This guide explains how vacuum insulated tumblers are classified in the U.S., which HTS codes apply to different materials, and how to estimate duties using real tariff data.<\/p>\n\n\n\n

1. What Is a Vacuum Insulated Tumbler?<\/h2>\n\n\n\n

A vacuum insulated tumbler is typically a double-wall container with a vacuum layer<\/strong> designed to keep beverages hot or cold. Most consumer products sold on Amazon or through U.S. retailers are made of stainless steel<\/strong>, have no glass inner<\/strong>, and hold less than 1 liter<\/strong>.<\/p>\n\n\n\n

2. Correct HTS Code for Most Vacuum Insulated Tumblers<\/h2>\n\n\n\n

\u2705 HTS 9617.00.1000 \u2014 Vacuum Flasks (Non-Glass Inner, \u22641L)<\/h3>\n\n\n\n

For the vast majority of consumer vacuum tumblers, the correct U.S. HTS code is:<\/p>\n\n\n\n

HTS 9617.00.1000<\/strong> \u2014 Vacuum flasks and other vacuum vessels, complete; excluding glass inners, capacity not exceeding 1 liter.<\/em><\/p>\n\n\n\n

You can verify current U.S. duty rates (including additional trade measures) here:

https:\/\/www.fiowind.com\/duty\/CN\/US\/9617-00-1000<\/a><\/p>\n\n\n\n

This is the preferred classification<\/strong> for stainless steel vacuum tumblers and thermos cups used for beverages.<\/p>\n\n\n\n

3. Why Material Matters: Commonly Confused HTS Codes<\/h2>\n\n\n\n

Many importers overpay duties because they classify products based on material alone<\/strong>, instead of construction and intended use. Below are HTS codes that are often confused with vacuum tumblers \u2014 and why they usually don\u2019t apply.<\/p>\n\n\n\n

\u274c Steel Containers (Not Vacuum Tumblers)<\/h3>\n\n\n\n

HTS 7310.10.0090 \/ 7310.10.0005<\/strong>
These codes cover iron or steel containers<\/strong>, such as industrial drums or cans (up to 300 liters), not consumer vacuum drinkware.<\/p>\n\n\n\n
