8504.31.20.00 - Unrated 🖩

This HTS category encompasses static transformers with a power handling capacity not exceeding 1 kVA. These transformers are designed to convert alternating current (AC) voltage from one level to another without the use of moving parts. Examples include small power transformers used in consumer electronics, lighting systems, and various control circuits where significant power transfer is not required. The key defining characteristic for classification within this subheading is the maximum power rating, specifically limited to 1 kilovolt-ampere.

Within the broader category of "Other transformers," this subheading is distinguished by its precise power limitation. While other transformer categories may cover higher power ratings or specific applications, this subcategory focuses on the lower end of power capacity for general-purpose transformers. The "Other" sibling category at this level would typically include transformers not specifically defined elsewhere within the 8504.31 or 8504.32 subheadings, potentially covering unique designs or very specialized applications not falling under the 1 kVA limit.

As this is a leaf node within the HTS, there are no further subcategories. Classification decisions at this level rely on confirming the transformer's power handling capacity and its status as a static transformer. Factors such as input and output voltages, winding construction, and intended use can be important in confirming the item aligns with the scope of static transformers not exceeding 1 kVA, differentiating it from any other specialized transformer types that might exist at a higher or more specific level of detail.
