MSDS Sheets For Shipping Speakers Internationally?

use the Make A Certificate sites on the web to write up something that says "inert components only" - add some borders and words like "certified"

then send that to them

So what is the issue? Magnets? I would search for details regarding hazardous materials, you may find information about magnets. What a crazy request. Either that or tell the seller to find another shipping company. You could also contact the shipping company for information about MSDS requirements with shipments. Put the pressure on them to tell you what you need. I'm guessing they just don't know what they're handling.

Here is a link for reference.....

I think I can make a MSDS sheet myself and send it to them.  

Cancel the sale.  There are no hazardous materials requirement for the Harbeth loudspeaker, so either the shipping company he is using is incompetent, the seller is making this up, or the seller cannot understand what the shipping company is telling him, in effect the seller is incompetent.  Under any of these circumstances the chances of you being a happy buyer are slim to none.  Walk away!
