How to pay Chinese suppliers from Mexico

How to pay a Chinese supplier from Mexico: the short answer

A Mexican company pays a Chinese supplier in three stages. It registers as an importer with the tax authority, it pays the supplier by bank transfer from an account in the company's own name, and it clears the goods through a customs broker with documents that match the payment. The payment is usually a SWIFT transfer in US dollars. SWIFT is the international messaging network banks use for cross-border payments, and each bank has an 8 or 11 character SWIFT code.

Mexico makes the dollar side simpler than most countries. Banco de México (Banxico), the central bank, lets Mexican banks open US dollar accounts for any company domiciled in Mexico, and those accounts can send dollars abroad by electronic transfer. A Mexican importer can therefore hold dollars and pay a supplier in China without converting pesos on the day of each payment.

The usual sequence for an order from China is:

1. Register in the Padrón de Importadores, the SAT register of importers, and appoint a customs broker.
2. Agree the price, the payment terms and the Incoterm with the supplier, and get a proforma invoice. An Incoterm is a standard trade term, such as FOB or CIF, that sets who pays freight and insurance.
3. Check the tariff rate for the goods, because Mexico raised import duties on 1,463 tariff lines from 1 January 2026 for goods without trade agreement preference, which includes goods from China.
4. Pay the deposit by SWIFT from the company's dollar or peso account, quoting the invoice number.
5. Pay the balance against a copy of the bill of lading, or use a letter of credit or a documentary collection.
6. Clear the goods on a pedimento, the Mexican customs declaration, with the value and contract details the broker transmits to customs.

This guide covers the Mexican side of each step. For the supplier's side, such as how Chinese factories invoice and how to pay a Hong Kong account, see our general guide on how to pay suppliers in China.

Mexican import rules that shape the payment

Mexico does not require a foreign exchange approval for an import payment. A company buys dollars from its bank, or uses its dollar account, and sends them abroad. The rules that shape a payment to China sit on the customs and tax side.

The Padrón de Importadores

Companies and individuals that import goods into Mexico must be registered in the Padrón de Importadores. SAT's published requirements are an active RFC (Registro Federal de Contribuyentes, the federal tax ID), a valid e.firma (the SAT advanced electronic signature), a registered tax address, a validated Buzón Tributario (the SAT electronic mailbox), being up to date with tax obligations, and a customs broker, customs agent or legal representative to carry out foreign trade operations. The company must not appear on SAT's lists under Articles 69 and 69-B of the Federal Tax Code, the second of which covers companies found to issue invoices for operations that did not take place. SAT states that it answers within 6 business days. Certain goods also need registration in the sector-specific register, the Padrón de Importadores de Sectores Específicos; your broker can confirm whether your goods are covered.

The 2026 tariff increase

A decree published in the Diario Oficial de la Federación (DOF) on 29 December 2025 amended the general import tariff law (LIGIE) from 1 January 2026. It changed 1,463 tariff lines, raising rates on many of them to between 10% and 35%. The largest groups are textiles (398 lines), clothing (308), steel (248), auto parts (141), plastics (79), footwear (49), paper and cardboard (47) and toys (37). The increases do not affect preferential treatment under Mexico's trade agreements, and Mexico has no trade agreement in force with China. Duty is paid on the pedimento, not to the supplier, but it changes the landed cost and so the order size you can fund.

The electronic value declaration

The importer declares the customs value of the goods in the Manifestación de Valor Electrónica (MVE), under Article 59, fraction III, of the Customs Law. From 1 October 2026 it is transmitted under rule 1.5.1 of the 2026 foreign trade rules. A new E15 format records each related contract: the parties, the date, the object, and the consideration, including the amount, the form and terms of payment and the currency. The importer declares this under oath. E15 is optional until 31 December 2026, but the contract must still be kept and produced on request. The payment terms you agree with the supplier are therefore part of the customs record.

How the money reaches a Chinese supplier

Most Chinese suppliers invoice in US dollars, and many invoice through a Hong Kong trading company with a Hong Kong bank account. A Mexican importer pays in one of the ways below. Whichever route you use, the beneficiary on the payment should be the company named on the invoice and in the contract you declare to customs.

Routes as described in this guide; supplier-side checks from PNC Bank's summary of China's goods trade foreign exchange rules. as published on 29 October 2026.

Paying from a Mexican dollar account

Article 46 of Banxico Circular 3/2012 allows Mexican banks to take US dollar demand deposits from companies domiciled anywhere in Mexico. Article 48 lists how those accounts can be debited, including electronic transfers in foreign currency. A dollar account can therefore receive dollars from your customers or from a peso conversion, and pay a supplier in China or Hong Kong directly. The same rule limits dollar accounts for individuals to people living within 20 kilometers of the northern border or in Baja California or Baja California Sur, so a sole trader elsewhere in Mexico pays from a peso account and the bank converts at its rate.

SPID (Sistema de Pagos Interbancarios en Dólares) is the Banxico system for dollar transfers between dollar accounts at banks in Mexico. It does not reach China. A payment to a Chinese supplier always leaves Mexico as an international transfer.

What the supplier's bank checks

China manages foreign exchange through the State Administration of Foreign Exchange (SAFE). As summarized by PNC Bank, a Chinese company must be on SAFE's list of companies with goods trade foreign exchange business, and banks cannot handle foreign exchange for companies that are not on it. The supplier's bank verifies each receipt using documents such as the contract, invoice and customs declaration. The same summary states that the remitter and the beneficiary must be the parties to the contract. A payment from a company that is not on the contract can be held while the supplier's bank asks questions.

Deposit, balance and payment terms

The payment term decides when money leaves Mexico and what you hold in return. Mexico sets no cap on advance payments for imports, so the limit is the risk you are willing to take with a supplier.

Payment terms as commonly used in trade with China; MVE contract data from Pérez-Llorca's note of 30 September 2026. as published on 29 October 2026.

A letter of credit (LC) is a bank's written promise to pay the seller when it presents documents that comply with the credit's terms. A documentary collection sends the shipping documents through the banks, and you receive them only after you pay or accept a bill of exchange. A supplier that has not traded with you before may ask for an LC on the first order and accept deposit and balance on later orders.

If the supplier asks for more than its usual deposit, for example 50% on a first order, weigh the amount at risk against an LC, and check the supplier's business license and bank details before you pay. A change of bank details by email just before a payment is a known sign of invoice fraud; confirm it by phone with a contact you already know.

What it costs: published bank charges

Each Mexican bank publishes its commissions. The table shows published charges from two banks for the steps in this guide, as examples of the items to budget for on each order. The amounts are in US dollars, and both banks state that IVA (value added tax) is added to every commission.

Sources: HSBC México, commissions for payments, and Banorte, Anexo de Comisiones de Servicios, as published on 29 October 2026. IVA is added to all amounts. Other banks set their own charges.

On a $50,000 order paid as a $15,000 deposit and a $35,000 balance, two OUR transfers at HSBC México's published rate cost USD 62 plus IVA. Three costs sit outside the tariff. The first is the exchange rate if you buy dollars with pesos, so ask for the rate before you confirm. The second is correspondent bank charges on the way to China, which OUR covers but SHA and BEN do not. The third is the cost of a correction or inquiry, at USD 60 at both banks, which is why correct beneficiary details matter.

The charge codes decide who pays the fees. OUR means you pay all transfer fees and the supplier receives the full invoice amount. SHA shares the fees, so intermediary deductions come out of the amount. BEN puts all fees on the supplier. A payment that arrives short delays shipment while the supplier queries the gap, so most importers paying China use OUR.

Documents that tie the payment to customs

The broker, customs and the supplier's bank each match the same set of facts: the supplier's name, the invoice number, the value and the payment terms. Keep them identical across every document.

Sources: SAT, Padrón de Importadores; Pérez-Llorca note on the MVE of 30 September 2026. Typical sequence; requirements vary by product. as published on 29 October 2026.

A bill of lading is the document the shipping line issues when it receives the goods. Ask the supplier to send a copy before you pay the balance, and check that the shipper, consignee and goods match the invoice. If the final invoice value differs from the proforma, tell your broker before the pedimento is filed, so the value declared to customs matches what you paid.

Agents, third parties and stablecoins: what goes wrong

Some importers pay through a sourcing agent who collects pesos in Mexico and pays the supplier from an account in China, or through a third party that settles in stablecoins. The facts below are what an importer should weigh before using these routes.

• The customs record names the contract parties. The E15 data in the MVE records the parties to the contract and how payment is made. A payment made by someone else does not match that record.
• The supplier's bank may query it. China's rules expect the payer to be the party on the contract. A transfer from an agent's account is a payment from a third party.
• There is no trace. A SWIFT transfer from your own account carries a reference and can be traced through the banks. Cash handed to an agent cannot.
• Tax deductibility needs a clean trail. Your accountant needs the pedimento and the payment from your own account to support the cost of the goods.
• Stablecoins sit outside Mexican banks. Banxico Circular 4/2019 allows banks and fintech institutions to use virtual assets only for internal operations, and does not allow authorization to offer clients exchange, transfer or custody of them. A USDT payment to a supplier therefore runs through a provider outside the Mexican banking system and creates no Mexican bank record of the import payment.

Where Helm fits

Helm is a financial technology company, not a bank. Accounts are held with regulated partner institutions. A Helm account gives your company USD account details in its own name, with a US routing and account number that receives ACH, Fedwire and SWIFT payments.

For a Mexican business that buys from China, it works like this:

• Pay suppliers in USD. Send international payments by SWIFT from your company's own account to the supplier's USD account in China or Hong Kong, with the rate, fee and expected arrival shown before you send.
• Use the dollars you collect. If you also sell to US customers, they can pay by ACH or Fedwire, and you can pay suppliers from the same USD balance without converting to pesos and back.
• Convert stablecoins. If a customer abroad pays you in USDC or USDT, you can receive them and convert them to USD inside the account, then pay the supplier by SWIFT from your company's name.
• Finance the order. Trade finance, such as supplier finance and working capital, is arranged case by case.

A Helm account sits beside your Mexican bank account, not instead of it. Duties and taxes on the pedimento are paid in Mexico, and dollar payments to other Mexican companies still run on SPID from a Mexican dollar account. Each account has a named account manager, and review questions are answered in writing within one business day. Helm agrees pricing with each business in writing before the account opens, and shows the rate, the fee and the expected arrival before you confirm each payment.

A checklist for paying a Chinese supplier from Mexico

• Register in the Padrón de Importadores and appoint a customs broker before the first order.
• Check the 2026 tariff rate for your goods before you agree the price.
• Put the parties, amount, payment terms and currency in a written contract you can declare in the MVE.
• Check the seller on the invoice, the contract and the payment are the same company.
• Confirm any change of bank details by phone with a known contact.
• Send each payment by SWIFT with charges set to OUR, quoting the invoice number.
• Pay the balance against a copy of the bill of lading, or use a letter of credit for a new supplier.
• Keep the SWIFT confirmations with the contract, invoice and pedimento for each order.
