Short News: CCC Mandatory Certification Officially Implemented for Fuse Industry

Zhejiang Zhenghao Fuse Co., Ltd.: Leading CCC Compliance, Building a Solid Safety Defense Line

Effective July 1, 2026, the State Administration for Market Regulation (SAMR) and the Certification and Accreditation Administration of China (CNCA) have officially implemented the new CCC mandatory certification rules for fuse-links (CNCA‑C02‑02:2026). The fuse industry has officially bid farewell to the era of enterprise self-declaration and entered a new phase of third-party mandatory certification supervision. As of today, certification bodies have fully accepted applications, and the entire industry has entered a critical sprint period to complete certificate conversion by December 31, 2026.

I. Policy Core: From "Self-Declaration" to "Mandatory CCC"

This adjustment stems from SAMR Announcement No. 57 of 2025, which formally reclassified fuse-links from the "enterprise self-declaration" model to third-party CCC mandatory certification. The new rules cover all categories of fuses, including low-voltage, photovoltaic, energy storage, EV charging, and chip fuses, requiring compliance for both domestic sales and export products.

II. Key Timeline

July 1, 2026 onwards: Certification bodies officially accept CCC applications and cease accepting new self-declarations.

Before December 31, 2026: All existing products must complete certificate conversion and cancel original self-declarations.

January 1, 2027 onwards: Fuses without CCC certification are prohibited from production, sale, and import, and violators will face penalties.

III. Upgraded Certification Requirements: Stricter Full-Process Supervision

After the implementation of the new rules, enterprises must complete the full certification process consisting of type testing + factory inspection + post-certification supervision:

Type Testing: Conduct comprehensive tests including breaking capacity, temperature rise, and durability in accordance with national standards such as GB 13539.

Factory Inspection: On-site verification of production consistency, quality system, and testing capabilities.

Supervision Inspection: Conduct irregular follow-up inspections after certification to ensure continuous product compliance.

IV. Industry Impact: Accelerated Consolidation, Enhanced Advantages of Leading Manufacturers

Increased Compliance Costs: Small and medium-sized manufacturers face additional investments in testing, certification, and system construction; some may exit the market due to cost pressures.

Standardized Market Order: Products with false declarations and substandard quality will be eliminated, further increasing industry concentration.

Reduced Export Barriers: CCC certification aligns with international standards, helping enterprises expand overseas markets.

Technology-Driven Upgrading: Demand for high-end products such as high-voltage DC and energy storage-specific fuses surges, driving technological iteration in the industry.

V. Recommendations for Enterprises

Initiate Certification Immediately: Prioritize certification for core models to avoid inventory backlogs and market disruptions.

Sort Product Catalogs: Classify products by voltage, breaking capacity, and application scenarios for batch applications to reduce costs.

Engage Authoritative Institutions: Select CNCA-accredited certification bodies and laboratories to ensure one-time approval.

Optimize Production Systems: Improve quality control to meet factory inspection and product consistency requirements.
