PSE and PSC Certification: Why ACP Alone Won't Get Your Products into Japan

If you're planning to sell physical products in Japan, having an Authorized Customs Procedure (ACP) arrangement is just the beginning. Many foreign companies discover — often too late — that Japan's product safety regulations require separate certifications that no customs procedure can replace. Two of the most critical are PSE (Product Safety of Electrical Appliances and Materials) and PSC (Product Safety of Consumer Products).

What Is PSE Certification?

PSE stands for Product Safety of Electrical Appliances and Materials, governed by Japan's Electrical Appliance and Material Safety Law (電気用品安全法, DENAN). Any electrical product sold in Japan must bear the PSE mark. There are two types:

◇ Diamond PSE (特定電気用品)

Required for high-risk electrical products that could cause fire, electric shock, or injury. These products must be tested by a registered third-party inspection body (登録検査機関) before they can be sold. Examples include:

Power cables and extension cords
AC adapters and chargers
Lithium-ion battery packs
Electric heaters and heating appliances
Transformers and power supplies
Medical-grade electrical equipment

There are approximately 116 product categories that fall under Diamond PSE. The key requirement is mandatory third-party testing — you cannot self-certify these products.

○ Circle PSE (特定電気用品以外の電気用品)

Required for lower-risk electrical products. While still mandatory, manufacturers can self-declare conformity through their own testing, provided they follow the prescribed technical standards. Examples include:

LED lighting fixtures
Television sets and monitors
Audio equipment
Refrigerators and washing machines
Electric fans
Personal computers and peripherals

There are approximately 341 product categories under Circle PSE. While self-certification is allowed, manufacturers must still maintain technical documentation and conform to Japan Industrial Standards (JIS) or IEC standards adopted by Japan.

What Is PSC Certification?

PSC stands for Product Safety of Consumer Products, governed by the Consumer Product Safety Act (消費生活用製品安全法). This certification applies to specific consumer products that pose safety risks, regardless of whether they are electrical or not.

Category 1: Specified Products (特定製品)

These require mandatory third-party inspection before sale:

Portable laser devices (laser pointers)
Baby beds and cribs
Portable pressure cookers
Riding helmets

Category 2: Specified Products with Self-Certification (特別特定製品)

Some products within Category 1 require additional inspection by a registered conformity assessment body designated by the government:

Baby beds (additional structural testing)
Portable pressure cookers (pressure testing)

Non-Specified but Reportable Products

Beyond PSC-marked products, the Consumer Product Safety Act also requires manufacturers and importers to report any serious product accidents to the Consumer Affairs Agency within 10 days. This applies to ALL consumer products, not just PSC-designated ones.

Why ACP Is Not Enough

Many foreign companies assume that once they have an ACP arrangement — which covers customs procedures, import duties, and consumption tax — they are cleared to sell in Japan. This is a dangerous misconception.

ACP handles customs clearance and tax obligations. PSE and PSC handle product safety certification. They are governed by completely different laws, administered by different government agencies, and require separate compliance processes.

Here's the critical distinction:

ACP is administered by Japan Customs (税関) under the Customs and Tariff Bureau of the Ministry of Finance
PSE is administered by the Ministry of Economy, Trade and Industry (METI / 経済産業省)
PSC is administered by the Consumer Affairs Agency (消費者庁) under the Cabinet Office

Having an ACP means your goods can enter Japan legally from a customs perspective. But if those goods are electrical appliances without PSE marks, or consumer products without PSC marks, they cannot legally be sold to consumers. Customs may even seize non-compliant products at the border if inspectors flag them.

The Testing Process and Timeline

Getting PSE or PSC certification is not a quick process. Foreign companies should plan for significant lead time:

Diamond PSE Testing

Timeline: 8-16 weeks typically, up to 6 months for complex products
Cost: ¥500,000 to ¥3,000,000+ depending on product complexity
Process: Submit samples to a registered inspection body → Testing against applicable JIS/IEC standards → Receive test report → Apply PSE mark
Registered inspection bodies include: JET (Japan Electrical Safety & Environment Technology Laboratories), JQA (Japan Quality Assurance Organization), UL Japan, TÜV Rheinland Japan

Circle PSE Self-Certification

Timeline: 4-8 weeks for internal testing and documentation
Cost: ¥200,000 to ¥800,000 (internal testing costs, documentation preparation)
Process: Conduct conformity testing → Prepare technical documentation → Register as a notified business operator with METI → Apply PSE mark

PSC Testing

Timeline: 6-12 weeks for specified products
Cost: ¥300,000 to ¥1,500,000 depending on product type
Process: Similar to Diamond PSE — submit to registered inspection body → Testing → Certification → Mark application

Penalties for Non-Compliance

Japan takes product safety violations seriously. The consequences of selling products without proper PSE or PSC certification include:

Criminal penalties: Fines up to ¥1,000,000 and/or imprisonment up to 1 year for individuals. Corporate fines can reach ¥100,000,000.
Product seizure: Customs can seize non-compliant products at the border
Compulsory recall: METI or the Consumer Affairs Agency can order mandatory product recalls
Business name disclosure: Violating companies are publicly named, causing severe reputational damage in a market where trust is paramount
Platform delisting: Amazon Japan, Rakuten, and other marketplaces actively remove listings for products lacking proper certification marks

Beyond PSE and PSC: Other Certifications You May Need

Product safety in Japan extends beyond PSE and PSC. Depending on your product category, you may also need:

TELEC (技適マーク): Required for any device with radio/wireless capabilities (WiFi, Bluetooth, cellular). Governed by the Radio Law.
Food Sanitation Act compliance: Required for food products and food-contact materials (kitchenware, packaging)
PMDA approval: Required for pharmaceutical products, medical devices, and cosmetics
JIS marking: While often voluntary, JIS certification can be a significant market advantage and is sometimes required for government procurement
SG mark: A voluntary safety mark administered by the Consumer Product Safety Association, but increasingly expected by major retailers

What OPTI Can Help With

At OPTI, we specialize in the compliance areas that complement product safety certification. Our core services include ACP (Authorized Customs Procedure) management and JCT (Japanese Consumption Tax) Fiscal Representative services. For tax filing and customs clearance, we work through established expert partners. Accounting and bookkeeping services are also available through our external partner network.

While PSE and PSC certification falls outside our direct service scope, we understand how these requirements interconnect with the broader compliance landscape. We can help you understand the full picture of what's needed to legally sell in Japan, and connect you with the right testing laboratories and certification bodies.

The Bottom Line

Selling physical products in Japan requires a multi-layered compliance approach. ACP gets your products through customs. JCT compliance keeps you legal from a tax perspective. But PSE and PSC certification ensures your products can actually be sold to Japanese consumers without legal consequences.

Think of it this way: ACP is your passport to enter Japan. PSE and PSC are your license to do business once you're there. You need both.

The companies that succeed in Japan are the ones that plan for all of these requirements before they ship their first container. The ones that fail are the ones who discover PSE and PSC requirements after their products are already sitting in a Japanese warehouse, unsellable.

Start your certification process early. Budget for testing costs. And never assume that one compliance checkbox covers everything Japan requires.
