Importing Machinery: Classification & Compliance
Importing machinery into the United States is mostly a classification and standards exercise: getting the HTS code right (which sets the duty), and meeting any safety, electrical, or environmental requirements that apply to the equipment. Most machinery classifies in HTS Chapter 84 (mechanical machinery and appliances) or Chapter 85 (electrical machinery and equipment), but the classification of a complex machine — and its parts — can be genuinely difficult. On top of customs, machinery often has to meet standards enforced by agencies other than CBP. This guide covers both sides — a specialized application of the general import process.
Classification: Chapters 84 and 85
Machinery generally falls under Chapter 84 (boilers, machinery, mechanical appliances) or Chapter 85 (electrical machinery, equipment). Classification drives the duty rate, and two issues make it tricky:
- Function vs components. A machine is usually classified by its principal function, but the section and chapter notes contain specific rules (including for machines that perform multiple functions and for “functional units” made of separate components).
- Parts. Machine parts may classify with the machine, under a parts heading, or — if they’re “parts of general use” (like fasteners) — under their own headings entirely, the same trap that appears with automotive parts.
Because the right code can be non-obvious and changes the duty owed, complex or high-value machinery is a strong candidate for a CBP binding ruling.
Beyond Customs: Standards That May Apply
Machinery frequently has to satisfy requirements enforced by agencies other than CBP, depending on what it is and how it’s powered:
| Concern | Possible requirement |
|---|---|
| Workplace safety | OSHA standards for equipment used in U.S. workplaces |
| Electrical safety | Compliance with recognized electrical standards; many buyers require a nationally recognized testing lab (NRTL) listing |
| Emissions | EPA standards for engines (e.g., nonroad/diesel engines) |
| Radio/electronic emissions | FCC requirements for equipment that emits radiofrequency energy |
| Refrigerants/ozone | EPA rules where applicable |
Not every requirement applies to every machine, but identifying which agencies’ rules touch your equipment — before it ships — prevents holds and post-import problems.
A Practical Sequence
Classify the machine (and its parts) under Chapter 84/85 using the section and chapter notes, confirming the duty rate and whether any additional trade-remedy tariffs apply. Identify the non-customs standards relevant to the equipment (safety, electrical, emissions) and confirm compliance and any required markings or documentation. File the entry with accurate classification and value, keeping records under the importer’s duty of reasonable care. For complex equipment, resolve classification uncertainty with a binding ruling rather than guessing.
Frequently Asked Questions
How is imported machinery classified?
Most machinery classifies under HTS Chapter 84 (mechanical machinery) or Chapter 85 (electrical machinery), generally by principal function, subject to the section and chapter notes. Machine parts may classify with the machine, under a parts heading, or — for parts of general use — under their own headings.
What duties apply to imported machinery?
Duties depend on the machine’s HTS classification, customs value, and country of origin, and additional trade-remedy tariffs may apply to certain machinery or origins. Because the classification sets the rate, accurate classification under reasonable care is essential.
What standards must imported machinery meet?
It depends on the equipment. Machinery may need to meet OSHA workplace-safety standards, recognized electrical-safety standards (often an NRTL listing), EPA emissions rules for engines, and FCC requirements for radiofrequency-emitting equipment. Identify which agencies’ rules apply before importing.
Should I get a binding ruling for machinery classification?
For complex or high-value machinery where the correct HTS code is uncertain, yes. A CBP binding ruling provides an authoritative classification determination before import, reducing the risk of an unexpected duty rate or a classification dispute later.
