Last updated: April 2026 dataVacuum flasks and insulated vessels — commonly known as thermos bottles — are segmented in the US tariff schedule by capacity: not over 1 liter (9617001000), over 1 liter but not over 2 liters (9617003000), over 2 liters (9617004000), complete with cases (9617002000), and non-glass parts (9617006000). China is the dominant supplier, with Vietnam a growing secondary source. Goods of Chinese origin in this category are subject to Section 301 tariffs, making Vietnam and other ASEAN suppliers increasingly attractive for supply-chain diversification.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The US schedule breaks vacuum vessels into three capacity brackets — not over 1 liter, over 1 liter up to 2 liters, and over 2 liters — plus a separate line for vessels sold complete with cases and another for non-glass parts. Importers should measure the actual internal volume and confirm whether the product is sold with a carrying case, as each condition maps to a distinct tariff line.
No. The heading explicitly excludes glass inners; replacement glass liners for vacuum flasks are classified elsewhere in the schedule. Only non-glass parts fall under 9617006000 within this heading.
