Wego is the Current Authorized Supplier to NHRA Via VP Race Fuels, It comes from a China Plant. I believe that they have more than 1 plant in China.
ProNitro* is distributed via TORCO** Racing Fuels to IHRA.
ProNitro is also supplied via west Coast Distributor HP-Racing - Dale Pulde to Nostalgia, Sand Drags, Hot boats and Nitro bike markets, We have 3 authorized plants in China supplying ProNitro Nitromethane.

Dow/Angus did in fact get out of drag racing fuels in late 05/ 06, first in the European market in the early spring, then at the end of last year they announced that the US provisions would also be ceased.This was the 2nd supplier to VP for NHRA Competition
There were rumours that the cost of Nitro will/ would be going WAY-UP. ($1000-1500 drum) While it caused a great stir in the racing ranks, this never came to fruition.
While there was a ingredient cost increase, the Price to the racer was stabilized with a slight if any cost increase.
