What types of transformers fall under HS-6 850421?

HS-6 850421 covers electrical transformers that use liquid dielectric insulation and have a power handling capacity not exceeding 650 kVA.

How can I determine if my transformer is under 650 kVA?

Check the manufacturer's specifications or the nameplate on the transformer, which should indicate its power handling capacity.

Can I use HS-6 850421 for transformers with different cooling methods?

No, HS-6 850421 specifically applies to liquid dielectric transformers. For dry-type transformers, you would need to use HS-6 850423.

What information do I need for customs when using HS-6 850421?

You need to provide details such as the transformer’s specifications, power capacity, and the type of dielectric used.

Are there any restrictions on importing transformers under HS-6 850421?

Check with your local customs regulations, as some countries may have specific import requirements or restrictions for electrical equipment.

How do I ensure accurate classification of my transformer?

Review the product specifications carefully and consult with a customs broker if you're unsure about the correct HS code.

What is the difference between HS-6 850421 and HS-6 850422?

HS-6 850421 is for transformers under 650 kVA with liquid dielectric, while HS-6 850422 is for those exceeding this capacity.

Can I classify a transformer with a capacity of 700 kVA under HS-6 850421?

No, a transformer with a capacity of 700 kVA exceeds the limit for HS-6 850421 and should be classified under HS-6 850422.

HS-6 850421: Electrical transformers; liquid dielectric, having a power handling capacity not exceeding 650kVA

Plain-language overview

Use HS-6 850421 when importing or exporting electrical transformers that use liquid dielectric and have a power handling capacity not exceeding 650 kVA. For example, if you're shipping a transformer designed for a small industrial application, this code is appropriate.

This code specifically covers transformers that utilize liquid dielectric insulation. In contrast, HS-6 850422 applies to transformers with a higher power handling capacity, exceeding 650 kVA, which are often used in larger industrial settings.

When classifying your product, note that HS-6 850421 is distinct from HS-6 850423, which includes transformers that are dry-type and not liquid-cooled. Understanding these differences ensures accurate customs declarations and compliance.

If you're unsure whether your transformer qualifies under this code, consider the specifications such as its cooling method and power capacity. These details are crucial for correct classification.
