Sourcing comparison · Solar Panels & Components
Tariff & fee savings only, assuming equal product cost — your actual landed cost also depends on price and freight, which vary by supplier.
| Annual import value | Estimated duty & fee savings / year |
|---|---|
| $50,000 | $26,375 |
| $250,000 | $131,875 |
| $1,000,000 | $527,500 |

Calculate your exact volume →The cheapest factory for solar panels & components is no longer always the cheapest landed cost — tariffs have reshuffled the math. Thailand's 13.5% effective rate undercuts China's 63.5% by enough to free roughly $52,750 a year at $100,000 of volume. Origin is one of the few cost levers a US importer controls outright, and it has rarely mattered more. Below, each tariff layer is laid out for both origins, with the saving scaled to several order sizes.
The gap is easiest to see by walking each origin's tariffs in turn. From China, the entry is assessed a 3.5% Most-Favoured-Nation base duty, a 50% Section 301 surcharge, and a 10% Section 122 reciprocal surcharge on its solar panels & components, an effective 63.5% once the $49.74 in processing fees are added. A Thailand origin attracts a 3.5% Most-Favoured-Nation base duty and a 10% Section 122 reciprocal surcharge on its solar panels & components, an effective 13.5% once the $49.74 in processing fees are added. Section 301's 50% China-only charge is what separates the two origins; strip it out and the stacks would look far closer. A Section 122 reciprocal surcharge is also in play — a temporary balance-of-payments measure scheduled to lapse in mid-2026, so its weight on this comparison is time-limited. 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 $5,275.00 per $10,000 shipment separates the two origins. A $25,000 order therefore differs by about $13,188, and a $100,000 year by roughly $52,750. Scaled to a single $25,000 PO, the gap is near $13,188, repeated on every reorder.
Classified in HTS chapter 8541.40, 8537, solar panels & components spans products like Solar panels (crystalline silicon), Thin-film modules, Solar inverters, and Mounting systems. The US imports solar panels & components 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. With no preferential deal in force, China solar panels & components faces the standard rates plus any applicable surcharge. From Asia-Pacific, Thailand's top US-bound categories include consumer electronics, auto parts components, and rubber. Absent a trade deal, Thailand's solar panels & components is assessed standard duties and whatever surcharges apply. With both origins in Asia-Pacific, freight lanes and transit times are broadly similar, so duty is the cleanest variable to compare. The recommendation is filtered to feasible suppliers, so Thailand appears because it plausibly makes solar panels & components, not merely because its rate is low. The figures here reflect the rules in force today; in a year of frequent revisions, the value is in re-running them as policy moves, which this site is built to do.
The headline is $52,750 at $100,000; because the rate gap is fixed, larger programs scale cleanly — $26,375, $131,875, and $527,500 at $50,000, $250,000, and $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. Subtract any per-unit premium Thailand charges from the duty saving to get the true net benefit before deciding. A quick checklist for the Thailand option: match the HTS classification, get a quote that itemises duty apart from freight, and check for any antidumping or countervailing order on your item. The saving is current today; given the pace of 2026 revisions, verify it again at contract signing. Model your exact volume and compare further origins in 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.
At $100,000 of annual import value, switching from China to Thailand saves an estimated $52,750 in duties and fees, because the effective tariff rate falls from 63.5% to 13.5%. The saving scales linearly with volume. 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.
Thailand-origin solar panels & components is assessed a 3.5% Most-Favoured-Nation base duty and a 10% Section 122 reciprocal surcharge, for an effective 13.5% duty rate before the Merchandise Processing Fee ($36.55) and Harbor Maintenance Fee ($13.19).
China carries an effective 63.5% rate versus 13.5% for Thailand. The gap is driven mainly by the 50% Section 301 surcharge that applies to Chinese-origin goods and stacks on top of every other layer.
Possibly. One of these origins currently carries the Section 122 reciprocal surcharge, which is scheduled to expire in mid-2026. The Tariff Savings Finder lets you toggle a post-expiry view to see whether the ranking shifts once that surcharge is removed.
