The full name of ST certification is the "Toy Safety Certification System" (Safety Toy), which is a mandatory safety certification system in Japan for toy products. Passing this certification proves that the toy meets Japanese safety standards, ensuring the safety of children when using the toy. Toys without ST certification cannot be legally sold in the Japanese market; therefore, all toys intended for sale in Japan must complete ST certification.

Scope of ST Certification

ST certification applies to all toy products intended for children under 12 years old. Specifically, this includes:

- Plastic toys, fabric toys, plush toys, etc.

- Educational toys and puzzle toys

- Mechanical toys (such as musical toys, remote-controlled toys, etc.)

- Any items that may be accessed by children under 12 for entertainment or educational purposes

Whether traditional toys or smart interactive toys, they are all subject to ST certification regulation.

ST Certification Specific Requirements

Part One: Physical and Mechanical Properties

This part specifies safety requirements for toys intended for children from newborns to 14 years old. It primarily assesses whether toys have sharp edges and dangerous points, and then, after abuse tests (stress, tension, twisting, impact, drop tests, etc.), evaluates whether they contain balls or small parts to prevent choking hazards. The stability of heavy stationary toys is also assessed to prevent injuries from collapse. Additionally, this part lists the methods for toy testing and specifies requirements for packaging and labeling.

Part Two: Flammability

This part mainly concerns toys worn on the head, including hair and touch toys; children's toys (including toy tents); and plush-filled toys, with qualification determined according to burning speed. The maximum burning speed specified in the standard is 30 mm/s.

Part Three: Hazardous Substances Testing

This part not only specifies limits for eight heavy metals in toy material surfaces, paints, and inks, but also requires testing for the migration of dyes, materials such as polyethylene and polyvinyl chloride, formaldehyde content in textiles, and phthalates (6P) testing.

Main Standards of ST Certification

The standards for ST certification are primarily based on Japan's Toy Safety Law (Toy Safety Standards). These standards cover multiple aspects, including:

1. Physical and Mechanical Safety: Ensuring that toys have no sharp edges or easily detachable parts to prevent injuries to children.

2. Chemical Safety: Ensuring that toys do not contain harmful substances, such as heavy metals or excessive phthalates.

3. Fire Safety: Certain toys, such as electronic toys, must have a certain level of fire resistance.

4. Hygiene Safety: Toy materials must be harmless and comply with Japanese hygiene standards.

5. Labeling Requirements: All qualified toys must display the ST mark and include warning instructions in Chinese or Japanese.

Through these strict standards, ST certification ensures the safety of children during play.

ST Certification Application Process

The process of obtaining ST certification is relatively standardized. Businesses can proceed according to the following steps:

1. Product Preparation: Prepare the toy samples that need certification and ensure they meet the relevant safety standards.

2. Choose a Certification Body: There are multiple certification bodies in Japan that provide ST certification services. Businesses can choose an officially recognized body to apply for certification.

3. Submit Application: Submit the toy samples, product manuals, manufacturing processes, and other materials to the certification body, and pay the certification fee.

4. Examination and Testing: The certification body will conduct comprehensive safety tests on the samples, including physical, chemical, and fire safety tests.

5. Obtain Certification: If the tests pass, the certification body will issue the ST certification certificate and allow the product to be sold in the Japanese market.

6. Labels and Compliance Marks: After certification, businesses need to mark the ST certification logo on the product and packaging to ensure compliance with Japanese market regulations.

Precautions for ST Certification

Long certification cycle: The testing and audit process for ST certification usually takes several weeks, so merchants should plan their time in advance when planning to enter the Japanese market.

Details determine success or failure: Some toys may fail certification due to minor design flaws or material issues, so merchants need to pay special attention to details during product design and production.

Regular reviews: Obtaining certification is not a one-time approval. If the toy's design or production changes, it may be necessary to resubmit the certification application.
