AUTHORIZATION TO USE BORIC ACID, U.S.P.,
IN SDA FORMULA NO. 40 IS REVOKED
Proprietors of distilled spirits plants
and others concerned:
This circular is issued to inform you that Revenue Ruling 63-249,
which will be published in Internal Revenue Bulletin No. 1963-47, of
November 25, 1963, will revoke Revenue Ruling 58-561 (C.B. 1958-2, 998),
which authorized the use of boric acid, U.S.P., as a substitute for
one-half of the brucine (alkaloid) or brucine sulphate in specially
denatured alcohol Formula No. 40.
Industry Circular 58-22, referring to the then-existing critical
shortage of brucine which developed as a result in the curtailment of
strychnine production, announced that boric acid, U.S.P., would be
authorized as a substitute for one-half of the brucine required.
This was accomplished by Revenue Ruling 58-561. Since brucine is no
longer scarce and since boric acid is no longer being used as a
substitute denaturant in Formula No. 40, Revenue Ruling 58-561 is
being revoked.
Inquiries regarding this circular should refer to its number and
should be addressed to the office of your Assistant Regional Commissioner,
Alcohol and Tobacco Tax.
