Caterpillar 3516C Diesel Generator Set
A heavy-duty diesel generator set with a 16-cylinder engine rated at 1,500 kVA output, designed for industrial power backup and prime power applications. It falls under HTS 8502.13.0040 because it uses a compression-ignition internal combustion piston engine and exceeds 1,000 kVA capacity. These sets are commonly used in hospitals, data centers, and construction sites requiring reliable high-capacity power.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as a complete diesel-electric locomotive power unit
Machinery with integral generating sets for specific transport equipment may shift to Chapter 84 machinery provisions.
If output is 75 kVA or smaller
Lower capacity diesel generators fall under the 75 kVA but not exceeding 375 kVA subheading based on rated power output.
If equipped with spark-ignition engines instead of diesel
Generating sets with gasoline or natural gas engines (spark-ignition) are classified separately from compression-ignition diesel types.

Import Tips & Compliance
• Verify engine output certification from manufacturer exceeds 1,000 kVA with supporting test data to avoid reclassification to lower subheadings
• Include detailed technical specs, emission compliance docs (e.g
• EPA Tier 4), and country-of-origin certificates for customs clearance
