Hello everyone i have a question,
what you do if Amazon in the Dangerous Goods Classification say We were unable to classify this ASIN… because it is not enrolled in FBA? When i added the product, Amazon say sell the product. What i do? I buy the product and send to Amazon anyway? Is a risk? ! 
thanks for your answers
If Amazon says that they were unable to classify your ASIN because it is not enrolled in FBA, it means that they cannot determine whether or not your product is a dangerous good. This could be for a number of reasons, such as:
The product is new and Amazon does not have enough information about it.
The product is a combination of materials that Amazon does not have experience classifying.
The product is unique and does not fit neatly into any of Amazon’s existing dangerous goods classifications.
If you are confident that your product is not a dangerous good, you can try to enroll it in the FBA Dangerous Goods Program. To do this, you will need to provide Amazon with a Safety Data Sheet (SDS) for your product. The SDS will provide Amazon with information about the product’s hazardous properties and how to safely handle and transport it.
If Amazon rejects your SDS, you may be able to appeal the decision. However, if Amazon still refuses to classify your product, you will not be able to enroll it in the FBA Dangerous Goods Program and you will not be able to send it to Amazon FBA.
If you are not confident that your product is not a dangerous good, or if you do not want to go through the process of enrolling in the FBA Dangerous Goods Program, you should not send your product to Amazon FBA. It is a risk to send a product to Amazon FBA that may be a dangerous good, as Amazon may refuse to accept the product or may even destroy it.
