英国采购需求：粉末加工、钣金、金属零件、钣金加工、金属加工、硅锰合金

I'm looking for alternative sources for Cobalt Oxide (Co3O4) for pigment manufacturing in the UK. Specifically, I need grades similar to industrial or ceramic quality with around 72-74% concentration. Can you confirm if you produce this in-house or if you're a distributor for another manufacturer? Also, I'd like to know if you have REACH certification and if you can export to the UK directly or if it requires a distributor. We are considering a volume of approximately +/- 50 tonnes per year. Please provide indicative pricing based on current cobalt market rates. Thank you!
