Most savings hide in the products you already import: an exemption nobody claimed, or a trade program left off the entry. HTS Hero checks every product for both, then prices every other country of origin.

Can we move the steel brackets to the Mexico supplier?
Worth asking your broker. If they qualify for USMCA, they could enter at 0%. We'll go through it on Thursday's call.

Stainless steel double-wall vacuum insulated water bottle, 32oz with leak-proof lid
Candidate headings
This is a complete vacuum-insulated vessel, not a steel kitchen article or residual container. Chapter 96 Note 1(d) and Section XV Note 3 keep vacuum flasks out of the base-metal headings. NY N353266 supports 9617, so that’s the heading I’m taking.
