1. Concise and Standardized Content, Highlighting Key Points
Use Standard Terminology: Hazard statements (H-codes) and precautions statements (P-codes) must use fixed phrases prescribed by regulations, avoiding self-created expressions.
Scientific Information Order: Arrange information in the order of "Physical Hazards → Health Hazards → Environmental Hazards." When multiple hazards coexist, prioritize displaying the highest risk information.
Avoid Redundancy: Do not repeat similar risks (e.g., "corrosion" already covers "skin irritation"). Ensure label content is concise and easy to read.
2. High-Contrast, Easily Identifiable Visual Design
Font Requirements: Use clear fonts such as bold or Songti for Chinese characters, with a font size no smaller than 3mm (approximately 1.8pt). Key information (such as chemical names and signal words) should be bolded and enlarged.
Foreign language text should not be larger than Chinese text and should be located below the Chinese text.
Strong Color Contrast: The background and text/graphics must have a clear contrast (e.g., white background with black text, black background with yellow text). Pictograms are uniformly displayed as black images on a white background with a red frame. The signal words "Danger" are highlighted in red, and "Warning" in orange.
Layout is logical: Information is layered and clearly prioritized to avoid overcrowding.
Add a black border to the label, leaving at least 3mm of blank space to improve overall readability.
3. Use durable materials suitable for the usage environment.
Select label materials based on storage and usage scenarios:
Ordinary environments: Waterproof coated paper with lamination.
Damp/Outdoor environments: Synthetic materials such as polypropylene (PP) and polyester (PET).
High-temperature/Corrosive environments: Aluminum foil labels or special self-adhesive labels resistant to chemical corrosion.
Printing inks should have UV resistance, fade resistance, and solvent resistance to ensure long-term legibility.
High-adhesion adhesive is recommended to prevent peeling and curling.
4. Labels should be prominently and securely affixed.
Labels should be affixed to the main viewing surface or most easily visible location of the container, avoiding obstruction, wear, or moisture.
For round containers such as drums and cans, the label should be affixed to the upper-middle side, ensuring it is visible at eye level when the container is standing.
When changing packaging, the receiving unit must affix compliant labels; original labels must not be reused.
Regularly inspect the condition of labels; replace them promptly if they are blurred, damaged, or detached.
