Face covering - created in the UK


I have started to sell face covering on etsy and I have an order from the US. My face covering is made using cotton material, with an elastic loop. There is no filter. It is not a medical product.

I need put in the customs code for my item when I am paying for postage with Royal Mail via Click and Drop. I have an online Business Account.

I have had a look and I believe the custom code I should be is 6307901000.

Would it be possible if I can get a sense check?

Kind regards
