I was puzzled as in the U.K. you can buy in 250 gm lots [hydroquinone] from Silverprint and there seems to be no limit as to how many lots you can have. So I was tempted to conclude that in the U.K. at least there wasn't a problem.
I have been busy trying to source hydroquinone at a lower cost along with borates & sulphites - Whilst it is possible to purchase Borax and Sodium Metaborate from ebay suppliers, one can never be sure of the purity when it arrives in ziploc bags. Hydroquinone and Sodium Sulphite proved to be difficult to find at a reasonable price online in the UK - Eventually bit the bullet and telephoned one of the two main London photographic suppliers... If you are buying in kilo quantities, it is well worth giving Process Supplies a call and asking for a bulk price
