1. Source Standardization: Unifying Rules to Prevent Deviations at the Root
Unified Templates and Assets: All labels directly adopt the official templates prescribed by the national standard *GB 15258-2009*. They utilize officially released standard GHS pictograms; unauthorized modifications to pictogram styles or color schemes are strictly prohibited. Only the two compliant signal words-"Danger" and "Warning"-are retained, thereby ensuring unified standardization right from the design stage.
Unified Information Sources: All information displayed on labels must be based on the *latest version of the SDS (Safety Data Sheet)*. Arbitrary citation of outdated information or the fabrication of hazard classifications is strictly forbidden, ensuring that the source of label information remains consistent across all batches of the same chemical product.
2. Three-Tiered Factory Verification: Simultaneous Validation of Accuracy and Consistency
Tier 1: Consistency Check
For different batches or different packaging specifications of the same chemical product, the label content must be absolutely identical. The chemical name, hazard classification, and UN number on the label must correspond exactly-without any discrepancies-to the content found in the corresponding SDS.
Tier 2: Specialized Accuracy Review
Designated personnel are assigned to conduct a specialized review of critical information:
Signal Word Alignment with Hazard Level: High-hazard chemicals must be labeled with "Danger"; downgrading the classification to "Warning" due to mislabeling is strictly prohibited.
Accurate Use of Pictograms: Pictograms must be used without duplication, omission, or modification, ensuring that every identified hazard is correctly represented by the appropriate symbol.
Accuracy of Basic Information: The 24-hour emergency contact number must be fully functional and reachable; the supplier's address and UN/CN numbers must be free of any data entry errors.
Tier 3: Physical Verification
Labels are cross-referenced against the actual chemical product to confirm that the hazard classification aligns with the label's markings (e.g., ensuring that a non-flammable chemical is not erroneously affixed with a flammable symbol). Additionally, the dimensions, margins, and placement of the label are inspected to ensure full compliance with formatting requirements.
3. Long-Term Management: Ensuring Sustained Accuracy and Consistency
Unified Version Management: All label templates are centrally archived and managed, with records maintained for version numbers, update timestamps, and reasons for modification. Whenever a template version is updated, all currently active templates are simultaneously replaced to prevent inconsistencies caused by the mixed use of old and new versions.
Periodic Review and Updates: A comprehensive review of labels across all product categories is conducted every six months to synchronize information with the latest regulatory requirements and SDS content, thereby correcting any outdated information. Furthermore, following any changes to product formulations or regulatory standards, all corresponding templates are updated immediately to ensure information consistency across all distribution channels.
Error Review and Optimization: Compile and categorize errors identified during past inspections, and update internal production guidelines to prevent the recurrence of similar discrepancies.
