Description
AC generators, output exceeding 750 kVA
HS Code 850164 covers large industrial AC generators with an output exceeding 750 kVA, subject to a 2.5% US duty rate.
Frequently Asked Questions
What are the specific import restrictions for large industrial AC generators (over 750 kVA) imported into Brazil under HTS 850164?
Brazil requires a specific Import License (LI) issued by SISCOMEX for generators over 750 kVA, which often involves additional technical reviews by ANEEL, the national electrical energy agency. Furthermore, importers must ensure the equipment complies with the Inmetro Ordinance 371/2020 technical standards for electrical safety and efficiency, requiring certification from an accredited body before customs clearance.
How does the incorporation of rare earth magnets affect the classification and duty rate of a large industrial AC generator exceeding 750 kVA?
The use of rare earth permanent magnets, such as neodymium, in the rotor assembly can shift classification from HTS 8501.64 to 8501.31 or 8501.32 for generators with permanent magnet excitation systems. This critical material distinction alters the applicable duty rate, as 8501.64 is for generators with electromagnetic excitation, while 8501.31/32 cover permanent magnet synchronous generators, which may have different tariff treatment.
Alternative & Related Classifications
Large industrial generators can be misclassified under 8502.39 for electric generating sets if the unit includes a prime mover (like a diesel engine). The distinction is that heading 8501 is for generators (alternators) alone, while 8502 covers complete generating sets. Additionally, specialized generators (e.g., for marine propulsion) may fall under 8501.31 if output is over 75 kVA but not exceeding 375 kVA. Parts for these generators, such as rotors or stators, are classified separately under 8503.00.
