In the “Evaluation Criteria for the Measurement Assurance Capability of Quantitative Packaging Product Manufacturing Enterprises”, there are a series of requirements for using the ‘C’ mark, including:
Weight: 5g-25kg
Volume: 5mL-25L
Length: No limit
01
Net Content Marking
Companies must clearly mark the net content of quantitative packaging products on the product packaging, and the net content marking must comply with the requirements of Articles 7 to 12 of the “Regulations on the Supervision of Quantitative Packaging Products”.
02
Net Content
The error of the net content of quantitative packaging products produced by companies must comply with the mandatory product standards and the requirements of Article 5 of the “Regulations on the Measurement Supervision of Quantitative Packaging Products”. The sampling, testing, and evaluation process during the measurement inspection of the net content of quantitative packaging products must comply with the requirements of the “Measurement Inspection Rules for Net Content of Quantitative Packaging Products”.
03
Packaging Materials
The materials used by companies to package quantitative packaging products must meet the requirements for measurement accuracy and must be able to prevent leakage and damage during the packaging (filling) and transportation processes.
04
Non-compliance Control
Companies must ensure that products that do not meet product standards or whose actual net content exceeds the allowable error are under controlled status to protect consumer interests.
05
Corrective Measures
Companies should analyze the reasons for measurement non-compliance of quantitative packaging products and determine the corrective measures taken. The implementation of corrective measures should be recorded.
The outer edge of the ‘C’ mark is a regular octagon, and the inner edge is a square; the proportions must meet the specified requirements.
When using the ‘C’ mark, it should be clear and visible, and it must not be removable under normal usage conditions.
The ‘C’ mark should be displayed simultaneously with the net content, either before or after the net content marking.
The character height of the ‘C’ mark should be the same as the specified height for the net content characters, with a minimum height of no less than 3mm.
The recommended color for the mark is black, but other colors can be chosen based on printing needs.
