Shipping from South Korea to Mexico: Ports, Duties, Docs

·Last reviewed:

Short answer: Containers from South Korea usually sail from Busan to Manzanillo or Lázaro Cárdenas; one carrier rotation on Flexport Atlas (checked October 31, 2026) shows about 14 and 16 days port to port. Mexico and Korea have no trade agreement in force, so Korean goods pay the general duty rate, including 2026 increases. A registered Mexican importer is required.

Information checked on October 31, 2026. This guide is for orientation; it is not legal or tax advice.

You make auto parts, electronics, steel or chemicals in Korea and have a buyer in Mexico. Or you are that buyer. Either way, the questions are the same: which port, how long, what duty, which documents and whose name goes on the import declaration. This guide answers them with dated sources.

How big is Korea–Mexico trade?

Large, and lopsided. According to Data México, the Ministry of Economy's statistics portal (using INEGI and Banxico data), Mexico's imports from South Korea in August 2026 alone were US$3,185 million, against exports to Korea of US$468 million: a monthly balance of minus US$2,717 million for Mexico.

The same portal lists "parts and accessories of machines" as Mexico's top purchase from Korea, both for all of 2024 (US$2,528 million) and for August 2026 (US$1,269 million). The main destination states are industrial: Chihuahua, Nuevo León and Baja California in 2024; Chihuahua, Nuevo León and Jalisco in August 2026.

At a business forum in Mexico City on September 25, 2026, Korean President Lee Jae Myung said Korea is Mexico's fifth-largest trading partner, with bilateral trade of US$20.6 billion "last year", as reported by The Korea Times. That figure is his, not an official Mexican statistic.

Is there a free trade agreement between Korea and Mexico?

No. As of October 31, 2026:

  • The OAS Foreign Trade Information System (SICE) lists Mexico's agreements in force, and the agreements signed but not yet in force. Korea appears in neither list.
  • The Ministry of Economy's page of agreements signed by Mexico (dated June 1, 2026) says Mexico has 14 free trade agreements with 52 countries. The only agreement with Korea it lists is the investment protection agreement (APPRI) signed in 2000 and promulgated in the Official Gazette (DOF) on August 9, 2002; the page also links a 2008 report to the Senate on negotiations with Korea. An investment agreement does not lower import duties.
  • On September 25, 2026, President Lee called for a "swift resumption" of negotiations for a trade agreement, and noted that the two economies "have yet to have a comprehensive trade agreement" (The Korea Times, September 26, 2026).

In practice, a Korean certificate of origin does not unlock a preferential rate in Mexico today.

What duty applies to Korean goods in 2026?

Without an agreement, Korean goods pay the general rate of their Mexican tariff line (fracción arancelaria, 8 digits) in the tariff schedule of the LIGIE. Two 2026 decrees raised many of those rates:

  • December 29, 2025 decree (in force January 1, 2026): new rates for 1,463 tariff lines by our count, from 5% to 50%. A transitional article says the Ministry of Economy may implement specific mechanisms for imports from countries with which Mexico has no free trade agreement in force.
  • April 23, 2026 decree (in force April 24, 2026): 185 more lines, from 5% to 35%. Its recitals state that originating goods from Mexico's treaty partners keep their preferential treatment when they meet the treaty's requirements.

Neither decree names a country. They hit goods that cannot claim a trade agreement preference, and Korean goods cannot claim one. Whether your product pays more depends on its fracción. Steel, auto parts, electronics and chemicals are all broad categories with many lines; check yours one by one. Our guide Did Mexico raise the duty on your HS code in 2026? explains how, and the tool ¿Subió mi fracción? (in Spanish) checks a fracción against the December decree.

On top of the duty, the importer generally pays the customs processing fee (DTA) and 16% VAT. Non-tariff rules (Mexican standards, or NOMs, and permits) also depend on the fracción.

What can lower the duty, in general terms. These are Mexican programs for the importer, not for the Korean seller, and none is automatic:

  • PROSEC (sector promotion programs) lets registered Mexican producers import certain inputs at a preferential duty, only to make the products listed for their sector.
  • IMMEX lets manufacturers and exporters import goods temporarily and defer duty and VAT. Deferring is not exempting, and duty can become payable in some cases.

Your buyer and its customs broker decide whether either applies. Changing a tariff line without a technical basis, or declaring an origin you cannot prove, is not an option.

Ocean routes: Busan to Manzanillo or Lázaro Cárdenas

Busan is the usual Korean origin port for containers to Mexico's Pacific coast. The two Mexican gateways are:

  • Manzanillo (Colima): the natural gateway to Guadalajara and western Mexico.
  • Lázaro Cárdenas (Michoacán): rail connections toward the Bajío and central Mexico.

The choice depends on final destination, the carrier's rotation for that sailing and congestion at the time, not on habit. See choosing a Mexican port for the full comparison.

These are approximate ranges, not delivery commitments. Schedules change from one sailing to the next, and published rotations are indicative.

Kold Gold works with partner carriers on Asia–Mexico lanes, including sailings that connect Busan with Mexico's Pacific ports, in full containers or consolidated cargo. Our route page Korea to Manzanillo / Lázaro Cárdenas (in Spanish) describes how we run it. For the service overview, see ocean freight.

Air option: Incheon to Mexico

For urgent electronics, samples or high-value parts, air freight from Incheon International Airport is the alternative. Cargo can arrive at Mexico City (AICM), Felipe Ángeles (AIFA) or Guadalajara (GDL), depending on the airline and the routing, which may include a connection through another hub. Ask for the routing, the arrival airport and the customs office in writing, because the customs office of entry is where the clearance takes place. Air changes the transit, not the rules: duty, VAT, the importer of record and the documents work the same way as for ocean cargo.

Documents for a Korea–Mexico shipment

Technical sheetKorean sellerNeeded to classify electronics, auto parts, steel and chemicals correctly and to identify NOMs and permits.
Pedimento (import declaration)Importer, through its licensed customs brokerFiled in the importer's name.
Electronic value declaration (MVE)ImporterSee below.

MVE. The Manifestación de Valor Electrónica is the importer's declaration of how the customs value was set. In a joint statement of October 2, 2026, the SAT, the customs agency (ANAM) and the digital agency (ATDT) said the deadline for the MVE was extended to October 31, 2026, and that from November 1, 2026 the MVE is transmitted gradually by customs regime, with definitive imports from January 15, 2027. According to the statement, this calendar comes from the SAT's first advance version of the Third Resolution of Amendments to the 2026 General Foreign Trade Rules, posted on the SAT portal. It is not yet DOF law: the latest amendment in the DOF, the Second Resolution of September 22, 2026, still reads "until September 30, 2026", and we found no Third Resolution in the DOF as of October 31, 2026. Confirm the rule in force with your customs broker before shipping. The importer files the MVE, not the Korean seller, but the seller supplies much of the data.

The importer of record requirement

A Korean company cannot simply ship to Mexico and clear the goods in its own name. For a regular commercial import, the importer of record must be a taxpayer registered in Mexico and listed in the importers' registry (Padrón de Importadores) kept by the SAT. Some goods also need the sectoral registry: Annex 10 of the 2026 General Foreign Trade Rules (DOF, January 14, 2026) lists 16 sectors, among them chemical products, steel, steel products and automotive, each covering specific tariff lines.

If you sell delivered (DDP), agree in writing who the importer is before you quote. Our guide importer of record in Mexico covers the options, and how to ship to Mexico walks through the whole sequence. Kold Gold does not register importers in the registry; the importer applies, and we confirm its status before the cargo ships.

Frequently asked questions

Does Mexico have a free trade agreement with South Korea?

No. As of October 31, 2026, Korea appears neither among Mexico's agreements in force nor among those signed but not in force in the OAS SICE list. The two countries have an investment protection agreement, which does not lower duties. Korea's president called for resuming trade talks on September 25, 2026.

Do the 2026 Mexican tariff increases apply to Korean goods?

They can. The December 2025 and April 2026 decrees set new general rates on specific tariff lines and name no country. Goods that cannot claim a trade agreement preference pay them, and Korean goods cannot claim one. Whether your product is affected depends on its 8-digit Mexican tariff line.

How long does shipping from Busan to Mexico take?

One published rotation, HMM's NW1 service on Flexport Atlas (checked October 31, 2026; the page does not date it), shows about 14 days from Busan to Manzanillo and about 16 to Lázaro Cárdenas, port to port. Door to door takes longer once loading, clearance and inland delivery are added. These are approximate figures, not delivery commitments, and change by sailing.

Can a Korean exporter be the importer of record in Mexico?

In general, no. For a regular commercial import the importer must be a taxpayer registered in Mexico and listed in the SAT's importers' registry. A Korean seller usually needs its Mexican customer, or another registered Mexican party, to import. Some steel, chemical and automotive lines also require a sectoral registry.

Does a Korean certificate of origin reduce Mexican duty?

Not today. Without a trade agreement in force, there is no preferential rate to claim with a Korean certificate of origin. The customs broker may still ask for evidence of origin for other purposes. Programs such as PROSEC or IMMEX depend on the Mexican importer's registrations, not on the certificate.
