Hope: look at the packaging
Look at the packaging and see the certificate. Generally, regular manufacturers, whether purely imported or domestically produced, will use Chinese or Chinese and English text marks on the packaging. If the packaging is full of English, be careful, it is likely that small manufacturers will deceive consumers' "smoke bombs." Regular manufacturers use environmentally friendly raw materials in order to maintain their reputation, and the behavior of small factories is difficult to guarantee. Another point is that the merchant is required to present the ISO14001 International Environmental System Certification and the China Environmental Label Certification.
