Plain-language overview
Use HS-4 3821 when importing prepared culture media designed for the growth or maintenance of micro-organisms, such as bacteria or viruses, as well as plant, human, or animal cells. For example, if you're shipping a sterile nutrient solution used in a laboratory for cell culture, this code will likely apply.
When deciding between HS-6 382100, which covers all types of prepared culture media, consider the specific use case of your product.
