Effect:

The biggest function of the “Health Certificate” is to detect and prove that the content of heavy metals in the materials of glass, ceramics, candle jars and other containers is within the range that is harmless to the human body.

Regarding glass jar and glass bottle :

The main material of glass is silica, which has been included in the list of exempted products.

About the ceramic jar :

After the ceramic is broken, it can be clearly seen that the internal structure has three layers, the innermost is the clay layer, the middle is the color layer, and the outermost is the silica crystal layer.Usually we refer to the color layer and the silica crystalline layer as the color glaze.
The surface that really comes into contact with food is usually covered by glaze, that is to say, the crystalline layer of silica is in contact with food. Therefore, under normal circumstances, the content of heavy metals in the color glaze on the surface of porcelain is up to the standard.
Because different colors of color glaze contain different components.
For example, the red glaze contains a higher proportion of iron elements, the black glaze contains a higher proportion of cobalt elements, and the white glaze contains a higher proportion of pickaxe and aluminum elements, especially the surface of the matte porcelain does not have obvious silica crystals. When the layer is removed, heavy metal testing needs to be done again to prove that the heavy metal content of the color glaze is harmless to the human body.

Status Quo:

At present, China Customs and China Commodity Inspection Bureau have canceled the test of health certificate. Glass, ceramics and candle jars usually exported from China have been changed to SGS for heavy metal testing and provide testing reports.

Some American customers still need to do heavy metal inspection at China Commodity Inspection Bureau and provide “Inspection Certificate For Ceramicware Shipped to the United States of America” ​​to customers.

Some Southeast Asian customers still require suppliers to provide “Health Certificate”, usually we will explain all the reasons and inform customers that China Commodity Inspection Bureau has cancelled the issuance of “Health Certificate”, if the heavy metal test report provided by SGS is acceptable, we will Use SGS test report instead of “Health Certificate”.
