Export of oil storage cotton to the European Union requires REACH testing. This is because the EU implements the REACH regulations on products circulating within the EU, which means that products within the EU must fulfill all obligations under the REACH regulations in order to be legally produced or imported.

The REACH testing project for exporting oil storage cotton to the European Union mainly includes testing the chemical safety of the product. Specifically, it is necessary to test whether the product contains chemicals that are restricted or prohibited by REACH regulations, and evaluate their potential risks to human health and the environment. These testing items may include chemical composition analysis, toxicity assessment, environmental impact assessment, etc.

The REACH testing method for exporting oil storage cotton to the European Union mainly includes the following steps:

1. Sample preparation: According to the testing requirements, prepare oil storage cotton samples that meet the specifications.

2. Chemical composition analysis: Use appropriate chemical methods to analyze and detect the chemical composition in oil storage cotton samples to determine whether there are chemical substances restricted or prohibited by REACH regulations.

3. Toxicity assessment: Conduct toxicity assessment on stored oil cotton samples, including testing for acute toxicity, chronic toxicity, allergenicity, etc., to assess their potential risks to human health.

4. Environmental Impact Assessment: Assessing the environmental impact of stored oil cotton during its use and disposal, including testing for biodegradability, aquatic toxicity, and other aspects.
