I'm a machine builder in the UK and

I'm a machine builder in the UK and I've ben asked to build a prototype machine for classifying (grading and separating) a ground mineral mixture. The machine is for use in the USA and hence will will eventually be exported to the USA where it will be trialed. Never having supplied anything to the States in the past this project raises lots of questions.

Please bear in mind the machinery will be electrically powered via a portable generators or will be direct driven from a diesel engine. It will comprise moving mechanical components, water pumps and water flow system and electrical controls. It is to be transported to operating locations either via trailer mounting or mounting on a truck.

1) This is just a prototype for my clients to evaluate. Must I build it to conform to any particular UL standards?

2) If I simply built it and shipped it to the USA could it be impounded by customs for not having any standards conformity documentation or labels?

3) Are there any particular UL standards for mineral grading machinerey. I had a look at the UL standards list and could not find any specific standards?

4) Are there any general standards for mineral processing / grading machinery?

Any general pointers to relevent standards would be appreciated.

Thanks, Mark
