How to import machinery and equipment from China to Mexico: flat-rack and open-top for oversized cargo, used-machinery rules, permits and fracción, NOM electrical safety and DDP.

Importing machinery from China to Mexico is mostly about **handling weight and dimensions correctly** and **getting the classification right** , because heavy or oversized equipment drives both the container choice and the customs treatment. Some machinery also needs **permits** , **NOM electrical-safety** compliance, or falls under **used-machinery** rules. This machinery guide follows the engineering, classification and Mexican clearance checkpoints that determine whether a quote is feasible.

## Key takeaways

- Machinery’s cost and container choice are driven by **weight and dimensions** — a single heavy machine may need a **flat-rack** or **open-top** rather than a standard box.
- **Ocean is the default** ; for **China→Manzanillo or Lázaro Cárdenas** , budget **30 to 45 days port-to-port** for the main leg, then add rigging, out-of-gauge handling and inland delivery. Air suits only urgent spare parts or small, high-value units.
- **Classification drives everything.** Machinery sits across **HS chapters 84 and 85** , and the right *fracción arancelaria* determines the duty rate, any permit, and any NOM.
- A permit, *dictamen* , **NOM-003** or **NOM-050** applies only when the exact classification and equipment fall within the current official scope; confirm before ordering.
- **Used machinery** faces stricter scrutiny in Mexico than new — verify the rules for your specific equipment before buying second-hand.
- As of 2026, plan for **duty (HS-specific) + IVA at 16%** ; confirm current rates, as tariffs are time-sensitive.
- A **DDP door-to-door** arrangement can coordinate freight, import and delivery only through a named eligible Mexican importer and licensed customs broker; feasibility, scope and price are confirmed on WhatsApp.

## Should I ship machinery by ocean or air?

For machinery, **ocean freight is almost always the answer** , because equipment is heavy and the per-kilo economics of air rarely make sense for it.

Air freight is reserved for **urgent spare parts** that are holding up a production line, or small, high-value precision units where speed justifies the premium. For a complete machine or a production line, ocean is the only sensible option on cost. The trade-off is time — plan around weeks, not days. The full comparison is in [air vs ocean freight from China](https://ch-shipping.com/blog/air-vs-ocean-freight-from-china) .

## Which container does machinery need?

The container choice depends on whether your machine fits, and loads, through standard doors — many do not.

- **Standard 20ft / 40ft:** fine for crated machinery and equipment that fits within normal internal dimensions and can be loaded conventionally.
- **40ft High-Cube:** the extra internal height helps for tall machines.
- **Open-top:** for equipment that must be **craned in from above** because it cannot pass through the doors.
- **Flat-rack:** for **over-width or over-height** machines that exceed container internal dimensions and need to be loaded onto an open platform.
- **Out-of-gauge (OOG) / breakbulk:** for genuinely oversized pieces that no container holds, moved as project cargo.

Heavy and oversized cargo also needs correct **lashing, securing and weight distribution** , and sometimes special handling at both ports. Get the dimensions and weight confirmed early, because they determine equipment, cost and feasibility. Our overview of [shipping container types and sizes](https://ch-shipping.com/blog/shipping-container-types-and-sizes) explains when each unit applies, and [how to pack and palletise export cargo](https://ch-shipping.com/blog/how-to-pack-and-palletize-export-cargo) covers crating and securing.

## How is machinery classified, and why does it matter?

Machinery is classified under the **Harmonized System** , mostly in **chapters 84 (mechanical machinery) and 85 (electrical machinery)** , and the exact *fracción arancelaria* decides your duty rate and whether a permit or NOM applies.

Getting this right matters more for machinery than for many goods, because:

- The **duty rate** is fracción-specific and ranges widely across machine types.
- Some fracciones require an **import permit** (*permiso previo* ) or a technical *dictamen* before clearance.
- **Electrical machinery** can pull in a **NOM** safety requirement.

Misclassification can mean an unexpected permit requirement discovered at the border, or the wrong duty. Our guide to [HS codes and tariffs](https://ch-shipping.com/blog/hs-codes-and-tariffs) explains how classification works; confirm your fracción before you order, not after the machine ships.

## What permits, NOM and used-machinery rules apply?

Beyond duty, machinery can trigger product-compliance and import-control requirements that must be sorted before shipping.

- **NOM screening:** check the exact fracción, electrical characteristics and intended use against Anexo 2.4.1 and the official scope of **NOM-003-SCFI** , **NOM-050-SCFI** or any other candidate standard. The broad label “machinery” does not establish that either NOM applies.
- **Import permits / dictámenes:** certain machinery fracciones require a prior permit or a technical opinion from the relevant authority. This is fracción-driven, so it is found at the classification step.
- **Used machinery:** Mexico applies **stricter scrutiny to second-hand machinery** than to new — additional documentation and, for some equipment, specific requirements can apply. If you are buying used, verify the rules for your exact equipment and fracción before committing, because retrofitting compliance on a used machine at the port is difficult.

Treat all of this as planning information, not legal advice — the official determination sits with Mexican customs and the relevant authority for your exact equipment.

## What duties and taxes apply to machinery?

For machinery, reconcile the freight with the fracción-specific duty, 16% IVA and DTA before pricing the shipment; the 2026 layers are:

| Component | What it is | Notes for machinery |
| --- | --- | --- |
| **Import duty** | Tariff on the customs (CIF) value | HS-specific; varies widely by machine type and fracción |
| **IVA** | Value-added tax | **16% as of 2026** , on customs value plus duty |
| **DTA** | Customs processing fee | A percentage of the declared value |

A few planning points:

- **The duty is fracción-specific.** Some machinery enters at low or zero duty; some does not. Confirm your exact code rather than assuming.
- **2026 tariff changes** apply only to classifications listed in the decree effective January 1, 2026. Check the exact machinery fracción, origin and current rate.
- **Anti-dumping duties** (*cuotas compensatorias* ) can apply to specific products and origins on top of normal duty — see [anti-dumping duties (cuotas compensatorias) on Chinese goods](https://ch-shipping.com/blog/anti-dumping-duties-cuotas-compensatorias-mexico) and check your fracción.

## Do I need to register as an importer for machinery?

For a commercial machinery entry, Padrón registration with an active RFC is generally the starting point. SAT publishes limited exceptions, so confirm the applicable procedure and importer before shipping.

Check Anexo 10 to determine whether the fracción needs a sector registration in addition to the general Padrón. A Chinese exporter without the required Mexican setup generally cannot be the importer of record. We can assess DDP and identify an eligible Mexican importer, with the named party and legal structure confirmed for the shipment.

## Who handles freight, rigging, customs and delivery? Our DDP option

If you would rather not coordinate each leg of a heavy shipment separately, we can assess a **DDP (Delivered Duty Paid)** structure and quote the confirmed scope in one price.

We can assess and arrange a compliant DDP structure for the agreed origin, equipment, freight, import and delivery legs. The named eligible Mexican importer, permits, NOM treatment, inclusions, exclusions and price are confirmed for the shipment on WhatsApp.

## Frequently asked questions

**Is it cheaper to ship machinery by sea or air?**
By sea, almost always — machinery is heavy and air’s per-kilo cost rarely makes sense for it. Air is reserved for urgent spare parts or small, high-value units.

**What container do I need for a large machine?**
It depends on dimensions: a standard box if it fits and loads conventionally, an **open-top** if it must be craned in, a **flat-rack** if it is over-width or over-height, and breakbulk/OOG for genuinely oversized pieces. Confirm exact weight and dimensions first.

**Can I import used machinery from China to Mexico?**
Often yes, but used machinery faces stricter scrutiny than new, with additional documentation and sometimes specific requirements by equipment type. Verify the rules for your exact fracción before buying second-hand.

**Does machinery need a NOM?**
Only if the exact classification and equipment fall within the official scope. Check Anexo 2.4.1 and the scope and exceptions of NOM-003, NOM-050 or another candidate standard before ordering.

**How long does machinery take to ship from China to Mexico?**
For a standard machinery booking on **China→Manzanillo or Lázaro Cárdenas** , plan roughly **30 to 45 days port-to-port** for the ocean leg. Flat-rack or open-top loading, rigging, customs and inland delivery can extend the full timeline, so confirm it on the quote.

## Get a quote for your machinery shipment

Machinery rewards getting the details right early: confirm the weight and dimensions so the right container is booked, classify the fracción so any permit or NOM is known up front, check whether duty, the 2026 tariff or anti-dumping duties apply, and register as an importer in good time.
