Do concrete admixtures need to apply for poetry production certificate? What kind of product catalog does it belong to?

What he said is that 3C is the compulsory certificate of antifreeze, while what you said is the production license. See if you are synthetic or compound. If it is composite, you can get the business license of building materials products, and then there are security, environmental assessment and fire protection, which are easy to pass, but if it is composite, it will be difficult! Even if it's environmental protection, you can't pass it, and it's even more difficult to approve the business license, because what you want to do is a chemical business license.
