Vietnam origin · HTS candidates
Vacuum flask import duty from Vietnam
Find US HTS candidates for vacuum flask from Vietnam, then check the current MFN and Chapter 99 stack. Vietnam-origin goods typically avoid Section 301, but AD/CVD and reciprocal rules may still apply.
Quick answer
9617.00.10.00
At a $10,000 customs value, the current Vietnam-origin total rate is about 7.2% ($720).
Classification risk & HTS split
Vacuum flasks classify under HTS 9617.00.10 (vacuum vessels not exceeding 1 liter — 7.2% MFN) or 9617.00.60 (vacuum vessels exceeding 1 liter — 6.9%), based on capacity. The vessel must be a true double-walled vacuum-insulated construction; single-walled insulated bottles go to other chapters (e.g. 3924 plastic, 7323 base-metal household). Food-contact testing under FDA 21 CFR §177 applies to interior liner materials regardless of HTS.
Vietnam origin context
Vietnam's stainless-steel vacuum flask production cluster sits primarily in Hai Duong and Bac Giang, with OEM lines serving the US private-label channel for thermos and tumbler brands. Vietnam-origin flasks under HTS 9617.00.10 / .60 avoid Section 301, but the BPA-free liner and food-contact compliance still routes through FDA. China-origin Sec. 301 overlay on 9617.00 is +7.5-25%, so the duty arbitrage is real — but verify the stainless steel grade (304 vs 201) before claiming SS quality in the import file.

This page provides candidates and reference math, not a CBP ruling. CBP makes the binding classification and duty determination at entry; AD/CVD, exclusions, and product facts still need separate review.

FAQ
How do I find the US HTS code for vacuum flask from Vietnam?
Start from the product name or local HS code, anchor on HS6, then compare US HTS candidate descriptions. Vacuum flask can split after HS6 by material, use, construction, or function; the applicable Chapter 99 overlays differ between Vietnam and China origins.
Does Vietnam origin trigger Section 301?
Typically no. Section 301 (9903.88.x) is China-origin only. If processing in Vietnam does not amount to substantial transformation, CBP can still rule the goods China-origin at entry. AD/CVD, reciprocal, and Section 232 may apply to Vietnam independently.
