Personally, I wouldn't be able to morally ensure my clients the niobium I use is ethical without knowing it for certain. Anyone can make a blanket statement like that- it does not reassure me that your suppliers are ethical. Is there any more proof you could show me your suppliers are ethical or if they are not giving you proof, you should pressure your suppliers into giving you this information. I feel this is your responsibility as a retailer.

Thanks for your reply! Do you know the rest of the supply chain? I'm concerned about the effect that digging up the large amount of ore has on the environment and also the welfare of the miners. I'm trying to make an ethics statement for my products that use your niobium but have no way of tracing it back to the mining source. I have been using your niobium sheet. I know it's a very difficult topic but starting a conversation is the first step. Thanks, Alice
