Persistent Organic Pollutants (POPs) are chemical substances that are harmful to humans and exist in or accumulate within the bodies of animals and plants, and circulate in the natural environment over extended periods. POPs are naturally occurring or synthetic organic pollutants characterized by persistence, bioaccumulation, semi-volatility, and high toxicity. POPs include pesticides, industrial chemicals, and by-products unintentionally generated during industrial processes. These pollutants can travel long distances through various environmental media (air, water, organisms), crossing borders and affecting human health and ecosystems even in areas where POPs were never used or produced, causing significant global harm.

SVHC ,“Substance of Very High Concern”, refers to any substance that has adverse effects on human health and the environment.

PAHs Testing

California Proposition 65 (also known as Safe Drinking Water and Toxic Enforcement Act) was enacted as a ballot initiative in November 1986. Prop 65 businesses are required to provide a "clear and reasonable" warning before knowingly and intentionally exposing anyone to a listed chemical “Known to the State” to cause cancer or reproductive harm.

RoHS Testing

Phthalates is a general term for compounds that result from the reaction of phthalic anhydride and alcohol. Such substances are mainly employed as plasticizers making plastics and rubber more pliable. They are widely used in electronic and electrical equipment (EEE), toys, coatings, inks, garments, packaging materials, detergents, lubricants, and personal care articles. But when the concentration of phthalates exceeds a certain level, it may disrupt the endocrine system of human bodies, bringing harm to the development and health of children.

To comply with California's Safe Drinking Water and Toxic Enforcement Act (Proposition 65), companies must conduct a scientific exposure risk assessment for substances listed in the Proposition 65 List that may be present in their products. This provides a clear, step-by-step framework to help companies determine if their products require a "clear and reasonable" warning label. The core of the assessment involves quantifying human exposure doses and comparing them with official safety thresholds. A complete exposure assessment typically follows the steps below, combining model estimation and experimental testing.

From small issues like paint peeling off phone cases or fading car buttons to major problems like outdoor equipment rusting and failing or electronic components short-circuiting, these seemingly "worn-out" problems often have a common culprit: environmental aging. Excessive humidity, sun exposure, salt spray corrosion, and high-temperature baking—products face environmental stress in real-world use that is far more severe than we might imagine. How can we predict a product's "anti-aging" capability in advance? Aging tests are a critical reliability assessment method. They simulate or intensify various conditions that a product might encounter in actual use, allowing for a quick evaluation of the durability, stability, and lifespan prediction of materials or products.

On January 22, 2025, the European Union officially published the Packaging and Packaging Waste Regulation (EU) 2025/40, also known as PPWR. This regulation will fully replace the existing Directive 94/62/EC on August 12, 2026, becoming the primary EU legislation for the management of packaging and packaging waste.

It is known that "Made-in-China" goes to international along with the development of China's economy. However, the growing purchasing capability and huge market potential of China capture the attention of great numbers of foreign exporters. As one of the largest markets, China has strengthened its quality surveillance on its market during recent years when competent authorities usually select some products on the China market for testing to check conformity. It deserves notice that accompanying measures (penalties, recalls, etc.) will be taken in case of any non-compliance. Manufacturers, importers and distributors to access China market had better send their products for testing prior to shipment.
