Switching glass & ceramics sourcing from China to Mexico

When glass & ceramics crosses a US border, where it was made now decides a surprising share of what it costs. The effective rate falls from 41% on China shipments to 16% on Mexico shipments — close to $26,375 per $100,000 of imports each year. For a category this exposed to surcharges, the sourcing map is effectively a pricing map. Below, each tariff layer is laid out for both origins, with the saving scaled to several order sizes.

How the tariff stacks compare

The gap is easiest to see by walking each origin's tariffs in turn. From China, the entry is assessed a 6% Most-Favoured-Nation base duty, a 25% Section 301 surcharge, and a 10% Section 122 reciprocal surcharge on its glass & ceramics, an effective 41% once the $49.74 in processing fees are added. Sourced from Mexico, the goods face a 6% Most-Favoured-Nation base duty and a 10% Section 122 reciprocal surcharge on its glass & ceramics, an effective 16% once the $49.74 in processing fees are added. China carries the 25% Section 301 China duty, a punitive layer that compounds on top of the ordinary tariff and has no equivalent on the Mexico side. The reciprocal Section 122 charge is the most volatile element of this comparison, set to expire and therefore worth modelling in both states. The Merchandise Processing Fee and Harbor Maintenance Fee are charged on customs value, not origin, so they sit at $49.74 on either stack and never contribute to the gap. Subtract one stack from the other and $2,637.50 per $10,000 shipment separates the two origins. Across a year that is roughly $6,594 on a $25,000 purchase order and about $26,375 on a $100,000 program. Per $25,000 order, $6,594 separates the two origins — small per shipment, compounding fast across a program.

Trade context

The category, HTS 69, 70, takes in Flat glass, Ceramic tiles, Glassware, and Porcelain tableware among other glass & ceramics. The US imports glass & ceramics at scale, so the origin mix for this category is unusually sensitive to tariff policy. From Asia-Pacific, China's top US-bound categories include consumer electronics, computers servers, and clothing garments. Absent a trade deal, China's glass & ceramics is assessed standard duties and whatever surcharges apply. From North America, Mexico's top US-bound categories include passenger vehicles, auto parts components, and consumer electronics. Mexico's USMCA membership can zero out duties on qualifying glass & ceramics, which is why it so often undercuts non-agreement origins. Spanning Asia-Pacific and North America, the two lanes differ in freight and transit, so weigh those against the duty saving. Mexico clears this category at a structurally lower rate than China, an edge that persists across order cycles rather than a spot-price blip. With the US running its highest average tariff in decades, concentrated exposure to one high-duty origin is now a measurable annual cost rather than an abstract risk.

Recommendation

For $100,000 a year of glass & ceramics, the move from China to Mexico is worth about $26,375, scaling to $13,188 at $50,000, $65,938 at $250,000, and $263,750 at $1,000,000. These are engine-computed stacks, not estimates: identical inputs on both sides except country of origin, so the gap is purely a duty result. These figures reflect tariff and fee savings only, assuming equal product cost — your actual landed cost also depends on price and freight, which vary by supplier. Treat the annual saving as the ceiling on switching cost: as long as moving to Mexico costs less than that, the change is accretive. Request parallel quotes from your China incumbent and a vetted Mexico source, then compare landed cost with the duty gap held constant. The saving is current today; given the pace of 2026 revisions, verify it again at contract signing. Run your own volume — and a post-Section-122 view — through the interactive Tariff Savings Finder. One origin still carries the Section 122 surcharge, due to expire mid-2026; the ranking can shift once it lapses.
