Korea Revises KC Safety Standard for Tablet PCs: What It Means for Large-Screen Smartphones

The Korean Agency for Technology and Standards (KATS) has revised the KC Safety Confirmation criteria for tablet PCs by increasing the minimum screen diagonal size from 17 cm to 20 cm.

As a result of this amendment, large-screen smartphones that were previously classified as tablet PCs for KC Safety Confirmation purposes solely due to their screen size will no longer fall under the tablet PC criteria. Instead, they will be clearly regulated under the Supplier's Declaration of Conformity (SDoC) framework applicable to smartphones.

The revised requirements will take effect on November 1, 2026.



Q1. Why were large-screen smartphones previously classified as tablet PCs?

Previously, devices with a screen diagonal of 17 cm or larger were classified as tablet PCs subject to KC Safety Confirmation. As a result, some large-screen smartphones with screen diagonals of 17 cm or more, such as the Galaxy Ultra, were also classified as tablet PCs and were required to undergo the KC Safety Confirmation process. This created additional regulatory burdens and product classification challenges for manufacturers and importers, who had continuously raised concerns about the existing requirements.

 

Q2. What is the difference between smartphones and tablet PCs under the KC safety requirements?

Smartphones are subject to the Supplier's Declaration of Conformity (SDoC), which allows manufacturers or importers to verify compliance with the applicable safety requirements through in-house testing or third-party testing before placing the product on the market.

In contrast, tablet PCs are subject to the more stringent KC Safety Confirmation scheme. Before they can be sold, they must undergo product testing by a designated safety certification body and complete the Safety Confirmation registration process.


Q3. What happens to products that have already been certified or inspected under the previous requirements? (Transitional Measures)

Products that completed KC Safety Confirmation, safety inspections, or received an exemption under the previous requirements before the effective date will be deemed to have complied with the revised requirements for the Supplier's Declaration of Conformity (SDoC) or the corresponding exemption.

Therefore, manufacturers and importers that have already completed the required procedures in accordance with the previous requirements will not be required to undergo a new certification process for the same products.

 

This amendment is intended to clearly distinguish the safety requirements for large-screen smartphones and tablet PCs, thereby reducing the regulatory burden on businesses and eliminating confusion in the marketplace.

Manufacturers and importers planning to introduce smartphones or tablet PCs to the Korean market should review the revised screen size threshold and determine which KC safety management category applies to their products before placing them on the market.
