Calculate your exact volume →A electrical wiring & conduit importer's margin increasingly turns on a single field on the entry: country of origin. At 19.5%, South Korea sits well above Mexico's 14.5%; on $100,000 of annual buying that difference is around $5,275. The duty line moves with paperwork, not production cost, which is why it rewards attention. The sections that follow show where every dollar of the difference comes from.
Start with the two duty stacks side by side. Shipped out of South Korea, the product is hit with a 4.5% Most-Favoured-Nation base duty and a 15% negotiated bilateral rate on its electrical wiring & conduit, an effective 19.5% once the $49.74 in processing fees are added. On the Mexico side, Customs applies a 4.5% Most-Favoured-Nation base duty and a 10% Section 122 reciprocal surcharge on its electrical wiring & conduit, an effective 14.5% once the $49.74 in processing fees are added. 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. Because the MPF and HMF ($49.74 combined) track customs value rather than origin, they wash out of the comparison entirely. The arithmetic difference between the stacks is $527.50 per $10,000 entry, all of it in the duty layers since the processing fees are origin-blind. Multiply across your volume and it is near $1,319 for $25,000 and about $5,275 for $100,000 a year. Scaled to a single $25,000 PO, the gap is near $1,319, repeated on every reorder.
Within HTS 8544, 7306, electrical wiring & conduit includes Romex wire, THHN wire, Armored cable, and Conduit pipe. The US imports electrical wiring & conduit at scale, so the origin mix for this category is unusually sensitive to tariff policy. South Korea's trade profile leans toward consumer electronics, passenger vehicles, and steel iron products, and it sits in Asia-Pacific. South Korea's bilateral deal substitutes a set rate for the reciprocal surcharge, a structurally different stack for electrical wiring & conduit. Mexico's trade profile leans toward passenger vehicles, auto parts components, and consumer electronics, and it sits in North America. Through USMCA, qualifying Mexico electrical wiring & conduit enters duty-free, collapsing the special-tariff layer to nothing. Spanning Asia-Pacific and North America, the two lanes differ in freight and transit, so weigh those against the duty saving. The recommendation is filtered to feasible suppliers, so Mexico appears because it plausibly makes electrical wiring & conduit, 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.
Where Mexico is a viable supplier, expect roughly $5,275 at $100,000, rising to about $13,188 at $250,000 and $52,750 at $1,000,000 as volume grows. Every figure is produced by the same tariff engine behind the site's calculators, holding FOB value, freight and insurance constant so only the duty effect of origin shows through. 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. If any price premium from Mexico is smaller than the duty saving, the switch still wins on net landed cost. Before acting, confirm the Mexico supplier classifies under the same HTS heading, can meet your volume and certifications, and faces no product-specific exclusion or quota that shifts the duty. Lock the comparison to a quote date; a surcharge added or lifted can change the ranking between negotiation and purchase order. Open the Tariff Savings Finder to rank every feasible origin for your specific volume. 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 South Korea to Mexico saves an estimated $5,275 in duties and fees, because the effective tariff rate falls from 19.5% to 14.5%. 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.
Mexico-origin electrical wiring & conduit is assessed a 4.5% Most-Favoured-Nation base duty and a 10% Section 122 reciprocal surcharge, for an effective 14.5% duty rate before the Merchandise Processing Fee ($36.55) and Harbor Maintenance Fee ($13.19).
South Korea carries an effective 19.5% rate versus 14.5% for Mexico. The gap comes from differences in the base, Section 122, Section 232 and bilateral rates that apply to each origin.
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.
