What safety standards does a three in one cart meet when used as a basket?

The three in one stroller, with its multifunctional integration advantages of "stroller+basket+bed", has become the mainstream choice in the infant and toddler travel products market. The basket mode is mainly suitable for newborns aged 0-6 months and infants who cannot sit independently. Its core is used for short distance travel, car carrying, and temporary placement, and its safety performance directly affects the safety of infants and toddlers. As the core functional module of the three in one stroller, the basket must comply with the general standards for baby strollers, the special standards for portable baby sleeping baskets, and relevant international regulations when used. Failure to meet any of these standards may result in safety hazards such as falling, squeezing, and suffocation. At present, a safety control system with national standards as the core and international standards as supplements has been formed in China, clarifying various safety standards for the three in one cart and basket mode, providing clear basis for industry production, market supervision, and consumer selection.
The basket module of the three in one stroller is not an independent baby basket product, and its safety standards need to take into account both the overall safety of the stroller and the safety of using the basket alone. The core includes five dimensions: material safety, structural strength, restraint system, protective design, and labeling standards. At the same time, strict special testing is required to ensure safety in handling, loading, temporary placement, and other scenarios. All standard requirements are formulated around the physiological development characteristics of infants and young children, to avoid safety risks such as fragile bones and inability to protect themselves in newborns.
1、 Core National Standard: Basic Compliance Requirements for Basket Use
The safety standards for the three in one stroller basket mode in China mainly refer to the "Safety of Child Care Products - Child strollers" (GB/T 14748-2025), "Technical Requirements for Portable Baby Sleep Baskets for Infant and Child Products" (GB/T 46975-2025), and relevant regulations of 3C mandatory certification. The three standards are interconnected and cover the full scenario safety requirements for basket use. The core requirements are as follows:
1. Material safety standards: eliminate the risk of toxic and harmful contact
As a component that infants and young children come into direct contact with, material safety is the primary standard for carrying baskets. According to the requirements of GB/T 46975-2025, all parts of the basket that come into contact with infants and young children, such as the main body, lining, and fabric, must strictly control the limit of harmful chemicals, clarify the limit requirements for 56 types of chemicals in 6 categories, including the total limit of phthalates not exceeding 0.1%, lead content less than 90mg/kg, formaldehyde release not exceeding 0.05mg/m ³ determined by climate chamber method, pH value and color fastness must meet the safety requirements of infant and young children's textiles, and eliminate the risk of exposure to toxic, harmful, and irritating substances from the source. At the same time, the main frame of the basket should be made of high-strength and odorless materials such as 6061-T6 aviation aluminum alloy and thickened carbon steel. The lining should be made of breathable, soft, and sweat absorbing baby grade fabric, without burrs or sharp edges, to avoid scratching the skin of infants and young children; The filling material should be made of environmentally friendly materials with a rebound rate of not less than 80%. It can quickly recover after being compressed by 50%, providing effective support while avoiding pressure on the bodies of infants and young children.
2. Structural strength standard: Ensure safe handling and loading
The core safety hazard of the basket lifting mode is the fall of infants and young children caused by structural looseness and fracture, so the structural strength standards are particularly strict. According to the requirements of GB/T 14748-2025 and GB/T 46975-2025, the basket needs to use an integrated molding frame without segmented splicing. The welding points should be seamless welded and double reinforced, without virtual welding or leakage welding. It can withstand a static load of 300N vertically, with a deformation of less than 10mm. As the core component for handling, the handle needs to be equipped with a locking mechanism, which can withstand a tensile force of more than twice the weight of infants and young children after locking, without looseness, fracture, or deformation. At the same time, the surface of the handle needs to be treated with anti slip and anti pinch to facilitate stable handling by caregivers. The connection between the basket and the trolley frame needs to be equipped with a dual locking mechanism. Only when the unlocking device is fully in place can it be separated to prevent the basket from accidentally falling off; The connection point needs to pass a torque test, and the torque of the fasteners should not exceed 2N · m to avoid loosening during use. In addition, the internal dimensions of the basket must comply with regulations. For baskets with an internal length greater than 800mm, the specific area height should not be less than 180mm. For baskets with an internal length less than 800mm, the core area height should not be less than 150mm to ensure sufficient activity space for infants and young children, while avoiding body shaking caused by excessive space.
3. Restraint system standard: prevent infants and young children from sliding or falling
When using a basket, the restraint system is crucial in preventing infants and young children from sliding or falling, and must meet strict strength and design requirements. According to relevant standards, the basket must be equipped with a five point safety belt, and the shoulder belt, waist belt, and crotch belt must be synchronously fixed. The width of the shoulder belt should not be less than 19mm, and the crotch belt must be forcibly used. The attachment point of the safety belt must withstand a tensile force of 150N for 1 minute without damage, and the buckle must withstand a tensile force of 200N for 1 minute without failure. The sliding amount should not exceed 20mm. The material of the safety belt should be high-strength nylon with a breaking strength of not less than 5000N, and the surface should be wrapped with soft material to avoid compressing the chest and crotch of infants and young children; After adjusting the tension, it is advisable to insert a finger into the gap between the seat belt and the infant's body to ensure fixation without affecting blood circulation and breathing. At the same time, the seat belt buckle needs to adopt a "dual action unlocking" design, which requires two consecutive actions to be manually completed before unlocking, to avoid infants and young children accidentally unlocking. The buckle opening force should be controlled between 40-60N, and the closing locking force should not be less than 15N, balancing operational convenience and safety.
4. Protection and detail standards: Avoiding hidden safety hazards
The protective design of the basket should be in line with the physiological characteristics of newborns, avoiding hidden dangers such as pinching, suffocation, and bumps. The standard requirement is that there should be no 5-12mm dangerous gap inside the basket to avoid jamming the fingers of infants and young children; The edge radius of all moving parts shall not be less than 2.5mm, simulating skin contact with no risk of scratching, and preventing sharp edges from being exposed. The head area of the basket should be equipped with an adjustable headrest that fits snugly against the newborn's C-shaped spine, providing neck support to avoid neck injuries caused by head shaking. The headrest material should be soft and breathable, and the height can be adjusted according to the baby's head circumference; The bottom of the basket should have anti slip design, making it difficult to slide when placed. At the same time, ventilation holes should be reserved to ensure air circulation and prevent infants and young children from lying flat for a long time, which may cause stuffiness and suffocation. In addition, the basket should be equipped with a detachable sunshade that can block sunlight and dust, as well as provide protection for infants and young children when used outdoors. The sunshade fabric should pass a flame retardant test with a burning rate of no more than 100mm/min.
5. Identification and Explanation Standards: Guiding Standardized Use
According to the requirements of GB/T 46975-2025, the basket should be clearly labeled with key safety information, including rated load capacity (usually 0-9kg), applicable age, 3C certification mark, manufacturer, production date, and testing certificate. At the same time, precautions for use, maintenance methods, and safety warnings should be listed to guide caregivers to use it correctly. The identification should be wear-resistant and durable. After 50 cycles of friction, the information retention rate should not be less than 90%, ensuring that it remains clear and recognizable even after long-term use; The product manual should provide detailed instructions on the connection and separation steps between the basket and cart, the wearing and adjustment methods of the safety belt, as well as warning content such as prohibiting overloading and improper handling, to avoid safety hazards caused by improper use.
2、 International standard: Supplement and improve safety control requirements
In addition to domestic standards, the three in one cart basket mode also needs to refer to internationally recognized standards such as EU EN 1888 and US ASTM F833. These standards provide more detailed requirements in structural testing, dynamic protection, and other aspects, complementing domestic standards to ensure product compliance in the global market.
The EU EN 1888 standard specifies that lifting baskets suitable for infants and young children under 6 months of age must pass rolling ball and weight tests to ensure the reliability of the restraint system; If the gap between the basket and the handle can be reached through the hip probe, it should also be reached through the large head probe to avoid the baby's body getting stuck; The locking mechanism should have at least two locking devices, and at least one device should automatically engage when deployed to avoid accidental unlocking. The ASTM F833-21 standard in the United States emphasizes the requirement that the basket must pass a dynamic collision test. When simulating a frontal collision of a vehicle, the peak acceleration should be controlled within 60g, the displacement should not exceed 50mm, and the peak head acceleration should not exceed 55g to ensure the safety of the vehicle during installation; At the same time, detachable small parts with a diameter less than 3cm are prohibited to avoid swallowing risks for infants and young children. In addition, international standards require the basket to pass a temperature cycling test, with 10 cycles in the range of -20 ° C to+60 ° C, and the structure should not crack or deform, ensuring safety in different environments.
3、 Special testing standards: ensure the implementation of standards
The safety standards for the three in one cart basket mode require strict specialized testing before it can be implemented. Products that fail the testing are prohibited from being sold on the market. According to relevant domestic regulations, the basket must pass the 3C mandatory certification along with the trolley. The core testing items include structural strength testing, restraint system strength testing, dynamic collision testing, drop testing, chemical hazardous substance testing, and sharp edge and point testing. Among them, the drop test requires the basket to be dropped from a height of 1 meter to a hard surface, with complete functionality and no signs of breakage or looseness; The vibration fatigue test requires 100000 cycles at a frequency of 5-50Hz without any failure; The flame retardant performance test requires a vertical combustion test to ensure that the fabric is not easily flammable.
Industry enterprises need to establish a sound quality control system, conduct sampling tests on each batch of basket modules, and entrust third-party laboratories with CMA/CNAS dual certification qualifications to complete the tests to ensure that all indicators meet the standard requirements; Products that fail the inspection must be immediately recalled and rectified to prevent them from entering the market. At the same time, the testing report must have legal effect and can be used for product launch, quality control, and market supervision verification.
4、 Industry standards and consumer guidelines
Currently, with the increasing demand for safe travel for infants and young children, the safety standards for the three in one stroller basket mode are constantly improving. Industry enterprises need to strictly follow relevant domestic and international standards, strengthen the research and production control of basket modules, abandon the practice of simplifying processes and selecting inferior materials, focus on optimizing structural strength, restraint systems, and protective designs, and improve product safety performance through technological innovation. At the same time, enterprises need to strengthen quality control in the production process to ensure that every basket product can pass special testing. At the same time, safety standards and operating procedures for basket use should be clearly marked in the product manual to guide consumers to use them correctly.
For consumers, when choosing a three in one stroller, it is important to pay close attention to the safety and compliance of the basket module. Firstly, priority should be given to products that have 3C mandatory certification and comply with GB/T 14748-2025 and GB/T 46975-2025 standards. Product testing reports can be viewed to confirm that all testing indicators of the basket module meet the standards; The second step is to inspect the structural strength, locking mechanism, and safety belt of the basket on site to confirm that the handle is securely locked, the safety belt is not damaged, the buckle operation is smooth, and there are no sharp edges or corners inside; The third is to check the labeling and instructions, confirm that the rated load capacity, applicable age, and other information are clear, and the precautions for use are clear. When using the basket, it is necessary to strictly follow the standard requirements, not exceed the load capacity, and not disassemble or modify the basket components at will. When handling, ensure that the handle is locked in place, and when placing, ensure stability and anti slip to avoid safety hazards caused by improper use.
The safety standard of the three in one stroller basket mode is an important guarantee for safeguarding the safety of infants and young children's travel. Its core is to avoid safety hazards from various aspects such as material, structure, and protection through scientific standard control. The industry needs to continuously strengthen the implementation of standards and promote the standardization and normalization of basket design and production; Consumers need to establish a scientific awareness of purchasing and using baskets, pay attention to the safety and compliance of baskets, in order to effectively utilize the convenience of baskets, provide safe and comfortable travel guarantees for infants and young children, and promote the healthy, orderly, and high-quality development of the infant and young children's travel supplies industry.
