Auto Parts from China to USA: Complete Document Checklist
Every commercial auto parts shipment needs a standard customs file. Engines, safety equipment, road tires, wireless electronics, used parts, and branded products need extra records because US agencies regulate their function, condition, or branding.
The Importer of Record remains responsible for the accuracy of the US entry, even when a customs broker files it. Before shipment, the importer must identify each part and the agency that regulates it.
The standard shipment file includes:
Commercial invoice
Packing list
Bill of lading or air waybill
HTSUS classification information
Country-of-origin information
Importer of Record details
Customs bond for an entry that requires one
Importer Security Filing for covered ocean cargo
Our page on shipping from China to the USA covers the wider customs and transport process. This article deals with the product-specific documents for auto parts.
Which Auto Parts Trigger Extra US Federal Documents?
No single US certificate covers every auto part. Four federal document routes account for the main regulated categories:
| Product Type | US Agency | Main Document or Marking | Responsible Party |
|---|---|---|---|
| Engines | EPA | Form 3520-1 or 3520-21 | US importer or authorized agent |
| Safety equipment | NHTSA | HS-7 and applicable FMVSS certification | Importer and regulated manufacturer |
| Road tires | NHTSA | DOT symbol and Tire Identification Number | Tire manufacturer |
| Wireless electronics | FCC | FCC grant, FCC ID, SDoC, or module records | Grantee or US responsible party |
Supporting evidence covers two other conditions:
Used or remanufactured parts: records showing the condition, value, original identity, and any EPA or NHTSA status.
Branded replacement parts: purchase and authorization records that establish the source and the right to use a protected mark.
Airbags, pyrotechnic seat belt pretensioners, and lithium-battery products also require dangerous goods transport documents when their classification falls under the applicable transport rules. Carriers use those records when they review the cargo for acceptance.
EPA Documents for Engines and Emission-Related Parts
EPA import declarations cover specified vehicles and engines. The EPA vehicle and engine import forms show the current forms and import codes. Transmissions, suspension arms, and ordinary body panels fall outside these engine declarations.
When to Use EPA Form 3520-1
EPA Form 3520-1 covers passenger vehicles, highway motorcycles, and their corresponding engines. The same form covers a loose engine intended for a light-duty vehicle, light-duty truck, or motorcycle.
The importer matches the manufacturer, model, build date, serial number or engine family, intended use, entry number, and EPA import code to the invoice and physical engine.
For a loose light-duty engine, Code W applies only when an EPA certificate covers the engine or will cover it before entry into US commerce. The supplier provides the certificate and engine records that establish this connection.
Which Engines Use EPA Form 3520-21
EPA Form 3520-21 covers heavy-duty highway, nonroad, marine, recreational, and stationary engines listed on the form. It also covers regulated engines already installed in vehicles or equipment.
The supplier's file identifies both the engine and equipment manufacturers, model numbers, serial number, build date, and engine family. A certified engine also needs a valid certification basis and a legible emission control label.
The importer must select the form code before booking. A code that calls for an EPA approval letter or a specific label needs that evidence in the file before entry.
Choosing an EPA Code for a Replacement Engine
Calling an engine a replacement does not create an exemption. The Form 3520-21 replacement-engine provision requires a compliant label, a manufacturer holding a current US EPA certificate of conformity, and the replacement conditions stated on the form.
Light-duty applications use Form 3520-1. Heavy-duty and nonroad applications use Form 3520-21. The supplier connects the replacement engine to its certificate, label, model, and intended installation.
An invoice description such as "used engine" or "replacement motor" lacks enough detail. The commercial documents must state the engine category, fuel type, model year, engine family, serial number, and intended installation.
Documents for Aftermarket Catalytic Converters
A standalone catalytic converter falls outside Forms 3520-1 and 3520-21. Federal Clean Air Act restrictions still govern aftermarket converters and products designed to defeat emission controls.
For an aftermarket catalytic converter, the manufacturer provides its legal name, part number, converter type, and approved vehicle applications. It also supplies the installation instructions, warranty information, and evidence supporting compliance with EPA policy. Any universal-fit claim must match the listed vehicle applications.
Tuning devices and delete kits require a separate Clean Air Act review. The product design and intended use determine whether EPA treats the product as a defeat device.
DOT and NHTSA Documents for Safety Equipment
NHTSA regulates motor vehicles and specified motor vehicle equipment under the Federal Motor Vehicle Safety Standards (FMVSS). Covered equipment includes brake hoses, brake fluid, lamps, reflective devices, glazing, seat belt assemblies, tires, rims, and certain warning devices.
How the HS-7 Declaration Works
The NHTSA import implementation guide explains how the HS-7 declaration states the lawful entry basis for a vehicle or item of motor vehicle equipment. The customs broker transmits the declaration data supported by the product records.
Equipment manufactured to an applicable FMVSS enters under the provision for conforming equipment. The manufacturer places the prescribed certification on the item or its delivery container. Equipment outside an applicable FMVSS uses the corresponding non-FMVSS declaration basis.
The product name, vehicle use, safety standard, certification marking, manufacturer, and import purpose determine the correct HS-7 basis.
What the Manufacturer Must Provide
NHTSA uses manufacturer self-certification. A generic "DOT certificate" provides little value unless it identifies the regulated product and the standard that applies to it.
Before production, the manufacturer confirms:
Applicable FMVSS: the exact standard covering the part.
Certification method: the required wording, symbol, code, label location, or container marking.
Product identity: the model number, part number, production location, and vehicle application.
Test support: records for the same design and production configuration.
Manufacturer filings: NHTSA identification and US agent details required for that manufacturer.
The importer then compares the certification mark and test records with the model, manufacturing plant, and configuration listed on the commercial documents.
Airbags and Seat Belt Pretensioners
Airbag modules, inflators, gas generators, and pyrotechnic seat belt pretensioners fall under both NHTSA requirements and dangerous goods transport controls. The importer uses the HS-7 basis and equipment certification for US entry. The carrier uses the transport classification and dangerous goods records to decide whether it will accept the cargo.
The section on airbags and automotive safety devices explains the required transport records.
NHTSA Filings for Foreign Manufacturers
A foreign manufacturer of FMVSS-regulated equipment files manufacturer identification under 49 CFR Part 566. It also designates a US agent for service of process under 49 CFR Part 551.
The manufacturer file contains its legal name, address, US agent details, applicable standard, test records, and label artwork. A trading company can appear as the seller on the invoice, while the compliance file must identify the factory that manufactured and certified the regulated equipment.
DOT Markings for Imported Tires
US road tires require the prescribed DOT symbol and Tire Identification Number (TIN) on the sidewall. An E-mark or a test report prepared for another market does not meet this marking requirement.
How to Verify a Tire's DOT Marking
A new tire manufactured under the current format carries a 13-character TIN molded into or onto its sidewall. The number includes codes for the manufacturing plant, manufacturer, and production date. Retreaded tires follow a different TIN structure.
Production photographs must show the actual sidewall. The importer checks four details:
The complete DOT symbol and TIN are legible.
The plant code matches the manufacturing location.
The size and tire type match the invoice.
The date code matches the production batch.
Records Required from the Tire Manufacturer
NHTSA assigns the plant code to the tire manufacturer or retreader. The code identifies the production location and forms the first group of the TIN.
The supplier provides records linking each tire to its manufacturer, brand, size, type, plant code, TIN format, and applicable FMVSS. The invoice and packing list separate passenger-car, truck, off-road, and retreaded tires by type and size.
Part 574 also assigns purchaser-registration duties to new tire manufacturers and brand owners. The importer needs a defined process for purchaser records and recall notifications.
Earthmover and other off-road tires require a product-use review. If the product falls outside the definition of motor vehicle equipment, the importer supports the relevant HS-7 basis with a statement describing the intended application.
FCC Documents for Auto Electronics with Wireless Functions
Auto electronics with Wi-Fi, Bluetooth, cellular, radar, or another transmitter fall within FCC equipment authorization procedures. Non-wireless digital electronics also need an FCC classification unless a specific rule exempts them.
Which Auto Electronics Need FCC Review?
The device design determines the FCC route:
| Device Type | Typical Auto Product | Authorization Route |
|---|---|---|
| Intentional radiator | Wireless dashcam, cellular GPS tracker, Bluetooth head unit, TPMS transmitter | FCC Certification |
| Unintentional radiator | Digital controller or non-wireless electronic accessory | SDoC or a stated exemption |
The supplier's technical file identifies the operating frequencies, wireless module, antenna, power level, photographs, and user manual. It must also state the proposed FCC authorization route. A CE report covers a different regulatory system and does not answer these US requirements.
How to Verify an FCC ID
A transmitter subject to FCC Certification needs a valid equipment grant. The FCC ID combines the grantee code and product code.
The importer checks the FCC ID in the FCC database and matches it to the label, manual, radio module, and finished product. The grant must cover the frequency range, equipment class, antennas, output power, and configuration used in the imported model.
Who Maintains the SDoC File?
The Supplier's Declaration of Conformity (SDoC) requires a responsible party located in the USA. The compliance information supplied with the product identifies the model, compliance statement, and US responsible party.
For imported SDoC equipment, the US importer holds this role unless another eligible US party formally assumes it. The responsible party maintains the design, production, test, and compliance records for the imported model.
Using a Certified Wireless Module
A certified wireless module remains subject to the conditions shown in its grant and integration instructions. These conditions cover approved antennas, installation, separation distance, host labeling, simultaneous transmitters, and any final testing.
The supplier provides the module grant, integration instructions, FCC ID, antenna specification, host label, and finished-product assessment. The assessment confirms whether the exterior needs a "Contains FCC ID" statement.
A finished device containing a lithium battery also needs the relevant battery shipping documents for its configuration and transport mode.
Records for Used and Remanufactured Auto Parts
Used auto parts have no universal federal certificate. Their records must establish the product identity, condition, customs value, and any EPA or NHTSA status that still applies.
How to Document Condition and Customs Value
The commercial invoice states whether the item is used, remanufactured, refurbished, or a core. It also lists the part number, quantity, unit value, and a specific product description.
The importer keeps the purchase order, payment record, photographs, grading report, serial-number list, and refurbishment record to support the declared value. Samples, warranty replacements, and cores still need a customs value based on an accepted valuation method.
EPA Documents for a Used Engine
Used or remanufactured condition does not remove the engine from EPA control. The original certification status, engine category, age, configuration, label, and intended installation determine the declaration basis.
The supplier photographs the emission label, manufacturer plate, serial number, build date, and complete engine. For a remanufactured engine, the supplier also records the original identity and all work performed. Changes to the fuel system, aftertreatment system, calibration, or application change the facts used to select the EPA code.
Drainage Statements for Used Components
Used engines, gearboxes, pumps, compressors, and hydraulic components can retain fuel, oil, coolant, or other fluids. Carriers, warehouses, and forwarders use a drainage statement to confirm how the supplier prepared the part. CBP does not require one universal drainage form.
The supplier signs a statement that identifies the part, drainage date, fluids removed, cleaning method, and responsible person. Photographs show sealed openings and the absence of leakage.
The forwarder classifies the cargo from the actual residue, component type, route, and carrier criteria. A drainage statement records the preparation work; it does not determine the transport classification.
When Customs Treats a Part as Scrap
A reusable core sent for rebuilding differs from damaged metal sold only for material recovery. The description, purchase terms, photographs, test results, and intended commercial use must support the status declared at entry.
Customs applies a different classification and valuation when the goods qualify as scrap. Fluids, batteries, or contaminated materials also trigger an environmental and transport review.
Proof for Branded and Replacement Parts
CBP can detain goods when it suspects counterfeit or infringing marks. Importers of genuine or licensed parts need records that trace the goods to the brand owner or an authorized supplier.
Proof of a Genuine or Licensed Supply Chain
Genuine parts originate from the brand owner or its authorized supply chain. Licensed parts carry a protected mark with permission from the rights holder. Independent aftermarket parts use their own branding and avoid marks or packaging that create a false impression of origin.
For genuine goods, purchase records trace the supply chain. For licensed production, the license or authorization identifies the trademark, covered products, territory, parties, and valid period. CBP can compare these records with recorded trademarks and information from the rights holder.
When Branding Does Not Match the Documents
The brand, model, and part number on the goods must match the invoice, packing list, license, catalog, and purchase records. This check becomes especially important when a trading company sells goods that carry another company's mark.
Pre-shipment photographs show the product, packaging, labels, molded marks, and carton marks. These images connect the commercial records and authorization file to the goods that enter the USA.
Document Problems That Delay or Stop US Entry
Four document problems account for many preventable entry delays:
Generic descriptions: Terms such as "auto parts," "accessories," or "electronics" omit the facts needed for classification. The description needs the part name, function, relevant material, vehicle application, condition, and part number. HTSUS heading 8708 does not cover every vehicle component.
Identity mismatches: EPA, NHTSA, FCC, invoice, packing, and label records must describe the same goods. The importer checks part numbers, models, serial numbers, manufacturer names, FCC IDs, and production dates. A signed cross-reference explains any legitimate difference.
Missing marks: The required certification mark must appear on the product or delivery container, even when a laboratory report is available. Production photographs confirm the DOT symbol, TIN, FCC ID, or other prescribed label before collection.
Wrong document owner: EPA declarations, FCC SDoC files, and NHTSA manufacturer records belong to different parties. The importer assigns each record to the party identified by the relevant agency before the broker files the entry.

Frequently Asked Questions
Does a Chinese CE Certificate Satisfy US EPA, DOT, or FCC Requirements?
No. CE documentation belongs to a different regulatory system. It does not replace an EPA declaration, HS-7 basis, FMVSS certification, FCC grant, or FCC SDoC file required in the USA.
Do Brake Pads Need DOT Certification or an HS-7 Declaration?
Brake pads have no brake-pad-specific certification mark under an FMVSS. They remain motor vehicle equipment, so the entry file uses the HS-7 basis for equipment outside an applicable safety standard.
Does a Mixed Auto Parts Shipment Need Several Agency Declarations?
Yes, when the shipment combines products regulated by different agencies. For example, an engine, road tires, and a wireless dashcam require separate EPA, NHTSA, and FCC records even when they share one commercial invoice and bill of lading.
Who Provides the Documents, the Factory or the Trading Company?
The factory provides product identity, test, certification, and label records for the parts it manufactures. A trading company provides the commercial sale documents and any supply-chain authorization, while the US importer completes the declarations assigned to it.
Is a Customs Bond Required for Every Auto Parts Shipment?
The entry type determines the customs bond requirement. Formal entries require a bond, while CBP applies different procedures to qualifying informal entries.
Can One Compliance Report Cover Several Auto Part Numbers?
Yes, when the report and supporting documents clearly cover every model and the differences do not affect compliance. A model cross-reference connects each imported part number to the tested model, hardware version, and relevant marking.
Do Aftermarket Parts Need Authorization from the Vehicle Brand?
An independent aftermarket manufacturer can sell parts under its own branding without vehicle-brand authorization. It needs authorization when the product or packaging uses another company's protected trademark, logo, or branded presentation.
