Key facts for Mexico buyers, as of October 2026
— SAT lists importer registration and representation conditions; the buyer's route needs an individual check.
— A used machine's prior-permit position must be checked by tariff fraction.
— NOM-174 has a defined new-machine scope; a used machine still needs its own conformity answer.
— CPTPP entered into force between the UK and Mexico on 22 June 2026.
— UK export zero-rating depends on exit and valid evidence within 3 months of the time of supply.
Sources are listed at the end of this guide. The buyer's Mexican customs agent checks the actual import route and taxes; the seller confirms export-VAT treatment.
What should I check before buying used machinery for Mexico?
Start with three names: the exact machine, the Mexican importer and the customs agent advising that importer. As of October 2026, Mexico's answers turn on the selected unit and its tariff fraction. A generic description such as “used excavator” or “farm tractor” is not enough for the permit, conformity or tax decision.
Build a machine file before discussing shipment. Record the make, model, serial details, condition, intended use and proposed fraction. Add clear photographs and the seller's available technical documents. This makes the questions concrete and helps keep every later document tied to the unit you intend to buy.
Ask the customs agent to sequence the decisions. The importer route comes first. The prior-permit and conformity questions follow. Duty, import VAT and origin evidence should be assessed only after the fraction and importer are identified. Freight belongs at the end of that chain, when the parties know what must be ready before movement.
Use the European machinery buying guide to organise your seller and condition checks. Arrange a pre-purchase inspection before committing to a machine. Those checks do not decide Mexican admissibility, but they reduce the risk of building an import file around the wrong unit.
Confirm the importer, fraction and order of decisions with the buyer's Mexican customs agent before money moves.
Who can import the machine into Mexico?
Settle the importer before the seller finalises its invoice. These are the October 2026 importer checks. Mexico's Tax Administration Service (SAT) lists an active Federal Taxpayer Registry entry, known as the RFC, a valid electronic signature called the e.firma, up-to-date tax obligations, a located tax address, a validated tax mailbox and Padrón de Importadores registration among its requirements.
SAT also lists a customs agent, customs attorney or legal representative among the importer conditions. That does not prove an exemption or one-off route for a particular buyer. Do not assume that a foreign buyer, private purchaser or occasional importer can use the same route as a registered Mexican business.
The practical question is not simply whether someone can receive an invoice. It is whether the named importer can make the planned declaration for this machine and appoint the right representative. Put the legal name, tax details and consignee wording in front of the customs agent before the purchase contract and transport document are fixed.
Do not build the transaction around an unnamed consignee. Identify the importer and align the consignee details before finalising the commercial and transport papers.
Confirm the named importer's eligibility, registration, representation and any exact-fraction exception with the Mexican customs agent.
Does used machinery need an import permit or NOM approval?
Keep the permit decision separate from the environmental standard. As of October 2026, the Economy Ministry has a prior-permit framework for used goods, but the selected machine's position is not known until its tariff fraction is checked against the current schedule.
Send the Economy Ministry and customs agent the same machine description. Ask them to identify the applicable fraction, whether it appears on the current schedule, what application is required and which documents belong with it. A cautious written answer is more useful than a general assurance based only on the machine's age or condition.
Official Mexican Standard NOM-174-SEMARNAT-2026 has a narrower stated subject. It concerns new diesel engines in new non-road mobile machinery in the stated 19–560 kW range. The Economy Ministry catalogue gives 18 November 2026 as its entry-into-force date.
The standard excludes agricultural machinery and engines intended for electricity generation from its scope. That exclusion does not establish unrestricted admission for an imported unit or answer which other standards apply. Used condition, engine hours, intended use and the machine's first-sale position still need a unit-specific answer from the relevant authority.
Two labels do not decide the case. “Used” does not answer the prior-permit question, and “agricultural” does not settle every import requirement. Keep the fraction, engine and intended-use evidence together.
Confirm the permit schedule and application with the Economy Ministry and customs agent, then confirm the engine and other applicable standards with PROFEPA or SEMARNAT and the agent.
What duty and VAT will apply to my machine?
Do not use a generic percentage in a buying decision. Here is the position as of October 2026. Duty depends on the selected unit, its live Mexican tariff fraction and any applicable origin evidence. The customs agent must provide the live Mexican tariff fraction, ordinary rate, any preferential rate and relevant amendment in writing.
Origin is a separate test. UK–Mexico trade guidance requires the agreement being used to be specified, and eligibility depends on the machine and its origin evidence. A machine standing in a UK yard is not, by that fact alone, proved to be of UK origin.
The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) entered into force between the UK and Mexico on 22 June 2026. That date alone authorises no tariff claim for a used machine. The agent and forwarder still need to decide the agreement, origin proof and route for the actual unit.
The import-VAT treatment and any credit available to the particular buyer are also unresolved. Do not assume one rate or credit outcome for every machine. Ask the buyer's accountant to work from the classification and transaction that the customs agent has identified.
Confirm the live fraction, duty treatment, agreement and origin evidence with the customs agent and forwarder; confirm import-VAT treatment and credit with the agent and buyer's accountant.
What checks apply to an imported tractor or farm machine?
Give a farm machine two separate reviews. These are the October 2026 checks. NOM-174 excludes agricultural machinery from its stated scope, but that narrow exclusion does not answer the complete import route for a tractor, implement or other farm-used unit.
Mexico's National Service for Agrifood Health, Safety and Quality (SENASICA) has an inspection framework covering used agricultural machinery. The current requirements for the selected unit still need to be obtained. Do not invent a cleaning certificate, assume a universal exemption or wait until loading to ask whether the machine's history matters.
Describe the machine's previous use and present condition honestly. Supply photographs of working areas, tyres, tracks, undercarriage, attachments and packaging when the authority or agent asks for them. If cleaning or treatment is required, the written answer should arrive early enough for the seller to act before collection.
A used-tractor buying checklist can help you assess identity and condition, but it does not replace the Mexican entry decision.
Confirm the machine's current requirement sheet, cleaning, certificates and entry office with SENASICA and the buyer's customs agent.
What must be agreed before shipping from the UK or Europe?
Only book transport after the import questions have owners. As of October 2026, a UK VAT-registered seller may zero-rate an export only if the goods leave the United Kingdom and it holds valid export evidence within 3 months of the time of supply.
Where the buyer's side arranges an indirect export, the UK seller may ask for a deposit equal to the VAT until it receives the evidence. Notice 703 also bars zero-rating in specified customer cases. These points belong in the seller's written invoice instructions, not in an assumption made after collection.
The freight plan is still live work. The sailing, freight mode, transit time, free days and inland arrangements for the selected machine must be agreed with the carrier, forwarder and Mexican haulier. Historical ports or timings are not an operating schedule for this shipment.
Measure the machine in its transport configuration and describe any attachment or loose item. Ask whether the proposed movement is accepted, how it will be loaded, what cover applies and who controls the inland hand-off. Keep those answers beside the importer and permit decisions.
Compare working with a buying agent with buying directly from the seller. Whichever route you choose, make sure one person owns each decision and no one mistakes export preparation for Mexican customs clearance.
Confirm the invoice and export-evidence treatment with the UK seller and its tax adviser; confirm acceptance, route, cover and inland terms with the carrier, forwarder and Mexican haulier.
The pre-purchase checklist
For the October 2026 position, work through these steps before you commit to a machine for Mexico:
— Name the Mexican importer and have its customs agent confirm registration, representation and any exception.
— Send the exact machine description, condition and proposed tariff fraction to the agent for a written permit answer.
— Obtain a machine-specific engine and standards answer that distinguishes used condition, hours and intended use.
— Obtain the current fraction, origin-proof and agreement treatment before relying on a tax figure.
— For farm-used equipment, obtain SENASICA's current requirements for the unit and its history.
— Agree the UK seller's invoice treatment and export evidence within 3 months of the time of supply.
— Agree live freight acceptance and inland arrangements for the machine's actual dimensions and weight.
Pause if any answer is still attached to a generic machine category rather than the unit you intend to buy. The point of the checklist is to expose an unanswered dependency while the seller can still supply information and the buyer can still walk away.
Keep every written answer with the machine file. If the seller changes the unit, configuration or invoice party, send the revised details back to the advisers before treating an earlier answer as usable.
Working with a buying agent who already does this
Euro Plant Finder works on the sourcing and export side. We find machinery in the UK and Europe, check the seller, arrange inspection, negotiate for the buyer and coordinate the export-side documents requested by the buyer's advisers.
The buyer's own Mexican customs agent confirms the tariff fraction, permits and tax treatment, then handles the declaration and local clearance. We coordinate with that agent so the machine identity and seller-side paperwork match what they request.

Can I import used machinery into Mexico from the UK or Europe?
A used machine may be importable, but there is no responsible blanket answer for every unit. As of October 2026, the named importer must meet Mexico's registration and representation conditions, while the exact tariff fraction drives the permit, duty and conformity questions. Agricultural and engine-related requirements also depend on the machine. Give its specification, condition, intended use and proposed fraction to a Mexican customs agent, and obtain the relevant authority answers before purchase or shipment.
What documents and importer registration do I need?
As of October 2026, SAT lists an active RFC, valid e.firma, up-to-date tax obligations, a located tax address, a validated tax mailbox and Padrón de Importadores registration among importer requirements. SAT also lists an authorised customs representative among its conditions. That is not a complete shipment pack. Ask the buyer's Mexican customs agent to confirm eligibility, representation, the exact-fraction route, origin evidence and the unit-specific documents before the seller finalises the invoice.
Does used machinery need a prior import permit?
Mexico has a prior-permit framework for used goods, but that does not mean every used machine needs the same permit. As of October 2026, the selected unit's tariff fraction must be checked against the current schedule. Send the full machine description and proposed fraction to the buyer's Mexican customs agent and the Economy Ministry. Ask them to set out the application and document route in writing before you commit to the purchase.
How much import duty and VAT does Mexico charge on used machinery?
Duty and import-VAT treatment depend on the selected unit, its tariff fraction, origin evidence and the buyer's position. As of October 2026, the live tariff fraction, ordinary or preferential rate, origin evidence, import-VAT treatment and buyer's credit position all need a transaction-specific assessment. CPTPP has applied between the UK and Mexico since 22 June 2026, but that date alone establishes no preference for the unit. Ask the Mexican customs agent and buyer's accountant for the written calculation before relying on a figure.
What checks apply to a used agricultural tractor?
Treat engine scope and plant-health treatment as separate questions. As of October 2026, NOM-174 excludes agricultural machinery from its stated scope, but that does not remove other rules for an imported tractor. SENASICA's framework covers used agricultural machinery, while the requirements for the particular unit still need an answer. Ask the Mexican customs agent, SENASICA and the relevant environmental authority to assess the tractor, its history and its intended use before purchase.
Can Euro Plant Finder handle the Mexico customs side?
Euro Plant Finder works on the sourcing and export side. We find machinery in the UK and Europe, check the seller, arrange inspection and coordinate export-side documents with the buyer's advisers. The buyer appoints a Mexican customs agent to confirm the tariff fraction, permits, taxes, declaration and local clearance. We do not act as the Mexican customs representative or make the import declaration, but we keep the machine information and seller-side paperwork aligned with that agent's requests.
