Singapore, Japan, and South Korea Strengthen IoT Cybersecurity Cross-Border Market Access

Selling a connected device across multiple Asian countries has traditionally meant repeating the same security testing again and again, once for each national scheme. That is starting to change. Singapore’s Cyber Security Agency (CSA), Japan’s Ministry of Economy, Trade and Industry (METI), and South Korea’s Korea Internet & Security Agency (KISA) have strengthened cooperation between their national IoT cybersecurity labelling schemes. For manufacturers, this move brings a more efficient path to reach customers across the region.

IoT Cybersecurity Cross-Border Market Access: Two Key Agreements

This development is built on two separate milestones:

• A Memorandum of Cooperation (MoC) between Singapore and Japan, effective from 1 June 2026.
• A Mutual Recognition Arrangement (MRA) between Singapore and South Korea, covering cybersecurity labelling for consumer smart products.

Together, these agreements align three major labelling schemes: Singapore’s Cybersecurity Labelling Scheme (CLS), Japan’s JC-STAR, and South Korea’s KISA CIC. Each scheme rates the security level of connected devices, but until now, a product certified in one country still needed a separate evaluation to enter another.

How the Technical Mapping Works

The agreements are not just political goodwill. They include real technical equivalencies between certification levels, based on shared international standards such as ETSI EN 303 645.

Recognized Equivalencies Between Schemes

Under the Singapore-Japan mechanism, Japan’s JC-STAR baseline level (STAR-1) is now recognized as equivalent to Singapore’s CLS Level 1. Under the Singapore-South Korea arrangement, South Korea’s KISA CIC Basic Level and above is recognized as meeting the requirements of CLS Level 3. This means a product already certified under one scheme can go through a simplified application process to gain the equivalent label in the partner country, rather than starting the entire evaluation from zero.

What This Means for Manufacturers

For companies building consumer IoT products, routers, smart home devices, and similar connected products, this alignment offers practical benefits. Certification through CSA can now support access to multiple Asian markets while cutting down on repeated evaluation work.

Fewer Duplicate Tests, Faster Time to Market

Product teams no longer need to treat each national requirement as a completely separate project. Instead, they can design against a shared security baseline and apply for equivalent labels more efficiently. This can shorten certification timelines, reduce testing costs, and make regional expansion more predictable for manufacturers planning multi-country launches.

Requirements Are Still Getting Stricter

While cooperation is increasing, standards are not standing still. Singapore has already announced plans to raise its minimum security requirements for certain device categories. For example, residential routers will need to meet at least CLS Level 2, up from Level 1, by 2027. Manufacturers should treat this alignment as an opportunity, not a reason to lower their guard on security investment.

Looking Ahead

This cooperation reflects a broader trend across Asia-Pacific: regulators are working to make cybersecurity requirements more consistent, even as they raise the bar on what “secure” means. For manufacturers with products sold in Singapore, Japan, and South Korea, understanding how these schemes now connect is becoming just as important as understanding each one individually.

Key Takeaways

• Map your product’s current certification level first. Check whether your existing CLS, JC-STAR, or KISA CIC certification qualifies for the new equivalency mapping before applying separately in each market.
• Plan around the simplified application process. If you already hold a baseline certification in one country, use the streamlined path instead of restarting evaluation from scratch — this can save real time and cost.
• Don’t treat CLS Level 1 as a long-term target. With Singapore raising router requirements to CLS Level 2 by 2027, build products to a higher baseline now to avoid re-certification later.
• Watch for further alignment. As more governments in the region pursue similar cooperation, keep track of new mutual recognition arrangements that could open additional markets.
• Get early guidance on scheme mapping. Because equivalency rules involve technical detail, consult a certification body or advisor before assuming your product qualifies for simplified recognition.
