What Construction Machinery Can You Import from China?

China manufactures different types of gasoline and diesel-powered machinery for construction, excavation, material handling, and industrial applications. The best choice depends on your project requirements, operating conditions, engine specifications, and purchase budget.

Diesel-Powered Construction Machinery

Diesel engines are widely used in heavy construction machinery because they provide the power and torque needed for excavation, earthmoving, and material handling.

Common products include:

  • Mini excavators and crawler excavators

  • Wheel loaders and skid steer loaders

  • Bulldozers and crawler tractors

  • Road rollers and soil compactors

  • Backhoe loaders

  • Telehandlers and material handling machines

Mini excavators are popular among landscaping contractors, utility companies, and residential construction businesses. Buyers can compare different operating weights, digging depths, bucket capacities, and engine configurations.

Gasoline-Powered Construction Machinery

Gasoline engines are more commonly used in compact machinery and light-duty construction applications.

Typical products include:

  • Small construction pumps

  • Plate compactors

  • Concrete mixers

  • Compact construction machines

  • Selected small excavation and material handling equipment

When comparing gasoline-powered models, check engine displacement, rated power, fuel consumption, and applicable emissions standards. Similar-looking machines may have different engine classifications and certification requirements.

New vs. Used Construction Machinery

New machinery generally comes with clearer manufacturing records, current technical specifications, and warranty documentation.

Used machinery requires additional checks before purchase. Pay attention to:

  • Manufacturing year and engine model

  • Operating hours and maintenance records

  • Engine condition and emission control components

  • Machine dimensions and operating weight

  • Hydraulic system and undercarriage condition

  • Availability of replacement parts

For used mini excavators, confirm that the engine and identification plates are clearly documented. A machine’s age alone does not guarantee an exemption from U.S. emissions requirements.

EPA Emissions Requirements for Imported Machinery

EPA emissions compliance is one of the most important considerations when importing gasoline and diesel-powered construction equipment into the United States.

The U.S. Environmental Protection Agency regulates emissions from nonroad engines installed in excavators, loaders, bulldozers, and other construction machinery. Requirements depend on engine type, rated power, displacement, production year, and applicable certification category.

EPA Requirements for Diesel Engines

Nonroad compression-ignition diesel engines are generally regulated under 40 CFR Part 1039, together with applicable provisions of Part 1068.

EPA emissions standards include different tiers, with Tier 4 requirements applying to relevant engine categories.

Before purchasing a diesel machine, request:

  • Engine manufacturer and model

  • Engine family identification

  • Rated power and displacement

  • Engine production year

  • EPA emission control label

  • Certificate of Conformity, where applicable

Do not rely solely on a supplier’s statement that an engine meets Tier 4 standards. Request the actual certification documents and confirm that they match the engine installed in the machine.

EPA Requirements for Gasoline Engines

Gasoline-powered nonroad machinery uses spark-ignition engines. Different engine categories follow different EPA regulations.

  • 40 CFR Part 1054: Covers applicable small nonroad spark-ignition engines and equipment.

  • 40 CFR Part 1048: Covers applicable nonroad spark-ignition engines above 19 kW.

A compact gasoline-powered machine may therefore have different emissions requirements from a larger industrial machine.

Buyers should confirm the engine category and certification status before placing an order rather than assuming that all gasoline engines follow the same rules.

EPA Form 3520-21 and Import Documentation

EPA Form 3520-21 is used to declare the emissions status of covered imported nonroad engines, including engines already installed in machinery.

Depending on the import category, buyers may need to provide:

  • Engine manufacturer and model

  • Engine family name

  • Engine serial number

  • Production year

  • EPA certification information

  • Applicable exemption documentation

The declaration is generally submitted to U.S. Customs and Border Protection (CBP) as part of the import entry process.

Certain new certified products may qualify for a documentation exception when the original engine manufacturer is the importer and the applicable certification and labeling conditions are met. Do not assume this exception applies to every machine purchased from a Chinese equipment supplier.

Used or noncertified machinery should receive an emissions compliance review before purchase. Noncompliant equipment without a valid exemption may be refused entry or require additional procedures.

For official guidance, consult the EPA engine import forms and requirements.

California CARB Requirements

If the machinery will operate in California, buyers should also review applicable California Air Resources Board (CARB) requirements.

California’s In-Use Off-Road Diesel-Fueled Fleets Regulation generally covers qualifying self-propelled off-road diesel vehicles rated at 25 horsepower or greater.

Depending on the equipment and fleet, requirements may involve:

  • Equipment reporting through CARB’s DOORS system

  • Equipment identification and labeling

  • Fleet emissions reduction

  • Restrictions on adding older vehicles

  • Applicable operating requirements

These are primarily in-use fleet regulations, not a universal CARB import license for every machine. Confirm the requirements for the specific equipment and intended operation.

How to Choose a Reliable Supplier in China

Choosing the right supplier is essential when importing machinery from China. A low purchase price does not necessarily mean good manufacturing quality or dependable after-sales support.

Verify the Manufacturer's Background

Before placing an order, check the supplier’s business registration, factory location, production capabilities, and export history.

Ask for:

  • Factory photos and production videos

  • Product catalogs and technical specifications

  • Previous export experience

  • References from buyers in similar markets

  • Warranty and after-sales service information

For larger orders, consider arranging a factory audit or using a sourcing agent to verify the manufacturer.

Compare Technical Specifications

A reliable supplier should provide detailed specifications for every machine model.

For mini excavators, compare operating weight, digging depth, bucket capacity, hydraulic performance, and engine power.

For bulldozers, review blade width, engine power, operating weight, and undercarriage configuration. For telehandlers, check the load chart because lifting capacity changes with boom extension and operating height.

If you need custom machines or specialized configurations, confirm production capabilities and delivery schedules before signing the contract.

Arrange Quality Control and Third-Party Inspection

A pre-shipment inspection helps identify defects before the cargo leaves China.

For gasoline and diesel machinery, inspection should cover:

  • Engine starting and running performance

  • Hydraulic system operation

  • Steering and braking functions

  • Operating controls and safety components

  • Machine appearance and identification plates

  • Attachments and accessories

Request factory test reports and arrange a third-party inspection when necessary. This is particularly important when purchasing multiple machines or customized equipment.

For a detailed checklist, see our Pre-Shipment Inspection in China guide.

Confirm Spare Parts and Warranty Support

Before confirming the purchase, ask whether the supplier can provide replacement filters, hydraulic components, engine parts, and other commonly used spare parts.

Clarify warranty coverage, payment terms, production schedules, and technical assistance in the purchase contract. Also confirm whether after-sales support is available for buyers in the USA.

For international orders, agree on the payment method, such as a bank wire transfer, and establish inspection and payment milestones.

Best Shipping Methods for Construction Machinery

The best shipping method depends on machine dimensions, gross weight, cargo volume, loading requirements, and the final destination in the United States.

Ocean freight is generally the most practical option for heavy machinery. Air freight is more suitable for urgent spare parts and smaller components.

Shipping MethodBest ForMain Consideration
FCLStandard-sized machineryContainer dimensions and payload
Flat RackOversized machineryLifting and lashing arrangements
Open TopTall or top-loaded cargoHeight and crane access
Ro-RoSelf-propelled machineryVessel and route availability
Air FreightSmall parts and urgent cargoHigher transportation cost

FCL Container Shipping

FCL is suitable for machinery that fits inside standard shipping containers.

  • 20GP: Suitable for compact machinery and smaller mini excavators when dimensions and payload permit.

  • 40GP: Provides additional loading space for compatible machinery or multiple units.

  • 40HQ: Offers additional internal height for suitable cargo.

Before booking, confirm machine dimensions, gross weight, loading points, and container payload limits. A machine that fits physically may still exceed the container’s permissible payload.

Flat Rack and Open Top Shipping

Large machines may not fit inside standard containers. Flat rack containers are suitable for oversized cargo, while open top containers can accommodate machinery requiring top loading or additional vertical clearance.

For oversized excavators, confirm lifting points, center of gravity, cargo securing, and port handling requirements before booking.

Ro-Ro and Air Freight

Roll-on/Roll-off (Ro-Ro) shipping is suitable for certain self-propelled machines that can safely drive onto and off the vessel.

Air freight is generally more appropriate for urgent spare parts, small components, and compact equipment rather than full-size excavators or bulldozers.

Prepare Machinery for International Transportation

Before loading, coordinate cargo preparation with the supplier and freight forwarder.

  • Remove or separately secure loose attachments.

  • Protect exposed hydraulic connections and electrical components.

  • Secure movable parts and operating mechanisms.

  • Confirm battery and fuel handling requirements with the carrier.

  • Prepare lifting points and cargo lashing arrangements.

  • Photograph the machinery before and after loading.

If wooden packaging is used, ensure it complies with applicable ISPM 15 requirements. Proper preparation helps reduce damage during loading, ocean transportation, and unloading.

U.S. Customs Clearance and Required Documents

Importing gasoline and diesel construction machinery from China to the USA requires accurate customs documentation, correct HTS classification, and compliance with applicable U.S. import regulations. Before shipment, buyers should prepare the required documents, verify engine emissions compliance, and confirm applicable import duties.

Essential Customs Documents

Prepare the following documents before shipping:

  • Commercial Invoice: Includes the machine description, model, purchase price, HTS code, and agreed Incoterms.

  • Packing List: Shows machine quantity, gross weight, dimensions, package numbers, and container details.

  • Bill of Lading (BOL): Confirms the international transportation arrangement and shipment details.

  • Certificate of Origin: Identifies China as the country of origin and supports customs verification and applicable tariff treatment.

Make sure the equipment description, declared value, and country of origin are consistent across all documents.

EPA and Equipment Compliance Documents

Gasoline and diesel-powered nonroad machinery must meet applicable EPA emissions requirements before entering the United States.

Depending on the engine category, prepare:

  • EPA Form 3520-21: Declares the emissions status of applicable imported engines and equipment.

  • EPA Certificate of Conformity: Supports engine emissions certification where required.

  • EPA Emission Control Label: Identifies the engine’s emissions certification information.

For used machinery, clean the tracks, tires, buckets, and undercarriage before export. Remove soil, mud, and plant debris to reduce the risk of USDA agricultural inspection problems.

Common HTS Codes and Import Duties for Construction Machinery

Most self-propelled construction machinery falls under Chapter 84 of the U.S. Harmonized Tariff Schedule (HTSUS), particularly heading 8429.

The following are common six-digit HTS classifications:

Machinery TypeCommon HTS SubheadingDescription
Crawler Excavators8429.52Machinery with a 360-degree revolving superstructure
Wheel Loaders8429.51Self-propelled front-end shovel loaders
Bulldozers8429.11 / 8429.19Track-laying and other bulldozers
Road Rollers8429.40Self-propelled tamping machines and road rollers

These rates represent general MFN base duties, not the final tax liability for Chinese-origin machinery. Additional tariffs, including Section 301 and Section 232 duties, may apply depending on the exact HTS classification and applicable trade measures.

The six-digit codes are for initial reference. Importers must confirm the complete 10-digit HTS code based on the machine’s specifications before filing a customs entry.

Check the U.S. Harmonized Tariff Schedule and consult a licensed customs broker to verify the current duty rates and additional tariffs.

ISF Filing and Customs Bond

For ocean shipments entering the USA, Importer Security Filing (ISF 10+2) must generally be submitted to U.S. Customs and Border Protection (CBP) at least 24 hours before vessel loading.

Importers must also arrange a customs bond to cover applicable customs obligations. The two common options are:

  • Single Entry Bond: Covers an individual import shipment.

  • Continuous Bond: Suitable for businesses importing machinery regularly throughout the year.

A customs broker typically handles the required entry documentation, including CBP Form 3461 and Form 7501, where applicable.

Customs Inspection and Clearance

CBP may inspect imported machinery to verify its declared value, country of origin, HTS classification, and supporting documents. EPA or agricultural inspections may also apply depending on the equipment.

Before shipment, check that the commercial invoice, packing list, engine information, and physical cargo details are accurate. Proper documentation, equipment cleaning, and timely ISF filing help reduce customs delays and unexpected charges.

Working with an experienced freight forwarder and U.S. customs broker can help coordinate the process from export preparation in China to customs clearance and final delivery.

How to Import Construction Machinery from China Step by Step

Importing machinery requires coordination between the manufacturer, supplier, inspection provider, freight forwarder, customs broker, and final delivery company.

Follow these steps to organize the process:

  1. Select the machinery and verify the supplier. Confirm the model, engine specifications, purchase price, production capability, and supplier background.

  2. Check EPA and local regulations. Verify engine certification, EPA declarations, and CARB requirements if the machinery will operate in California.
