The GST rate and HSN code for disposable plate, cup, glasses and related products depend on the material and type of the products. According to the web search results, some possible GST rates and HSN codes are:
12% GST rate and 7013 HSN code for glassware of a kind used for table, kitchen, toilet, office, indoor decoration or similar purposes123. 18% GST rate and 3924 HSN code for tableware, kitchenware, other household articles and hygienic or toilet articles, of plastics. 5% GST rate and 4823 HSN code for paper cups, plates and napkins. 12% GST rate and 4419 HSN code for tableware and kitchenware, of wood.
As I mentioned before, the GST rate on paper is 12% and the HSN code is 48181. However, I could not find any specific information on the GST rate on dried leaves. It seems that they are not classified under any of the existing HSN codes for paper or paper products.
