ceramic products, as traditional materials for food contact, are ubiquitous in the daily lives of people worldwide. items such as bowls, cups, soup pots, tea sets, knives, ladles, plates, and dishes are commonly made of ceramic materials. ceramics are generally perceived by the public as safe, non-toxic, and healthy materials for daily life. they come in diverse shapes, with smooth and delicate surfaces, vibrant colors, and are easy to clean, making them highly favored by many. however, ceramic products still pose safety risks, primarily stemming from the glazing process. glazes often contain sodium silicate and metal salts, and coloring pigments may also include metal salts, leading to the potential leaching of heavy metals. therefore, countries worldwide have established clear regulatory requirements for ceramic products.

china

china's control requirements for ceramic products are based on gb 4806.4-2016. the standard classifies ceramic products into six categories, each with different lead and cadmium leaching conditions and limits based on their use:

  • cookware: 4% acetic acid, 98°c, 120 minutes;
  • microwave-safe products: 4% acetic acid, 100°c, 15 minutes; and
  • other room temperature conditions: 4% acetic acid, 22°c, 24 hours.

if the individual test sample data does not exceed the listed limits, it is considered to meet the standard requirements. additionally, if the individual test sample data exceeds the listed limits but not by more than 50%, an additional three parallel samples are required. the average of the four test sample data must not exceed the limits, and no single sample result should exceed 50% of the limits, for it to be considered compliant with the standards.

germany

all ceramic and glass products placed on the german market must comply with the din 51032:2017 standard.

france

france's control project for ceramics involves testing for the leaching of lead, cadmium, aluminum, cobalt, and arsenic, with stricter control over the types of elements compared to other countries.

italy

glass products exported to italy must meet the requirements of ministerial decree of 21/03/1973. testing is required to confirm the glass category and usage, including three types:

  • high borosilicate glass & soda lime glass: for use at temperatures >80°c;
  • soda lime glass: for use at temperatures ≤80°c; and
  • lead-containing glass: for short-term repetitive use.

among them, all three types of glass products (a, b, c) require testing for overall migration. for class c, lead-containing glass (crystal glass), additional testing for specific lead migration is also required.

the united states

the control requirement for ceramics in the united states is the release of lead and cadmium, corresponding to fda cpg sec.545.450/7117.07 and fda cpg sec.545.400/7007.06.
