Was Unistat exempt when designed to be mixed into animal feed as a growth stimulant or disease preventive?

Short answer Yes. California classified Unistat and the two companion preparations as exempt feed because they were designed for incorporation into animal feed.

Plain-English summary

Unistat was classified as exempt feed because it was designed as a growth stimulant or disease preventive and its instructions directed users to mix it into animal feed.

The same conclusion applied to 3-Nitro Powder and Polystat No. 2. The letter said sales-tax reimbursement should not be charged on sales of the three preparations under section 6358 as then cited.

Attention:

Now: SR -- XX-XXXXXX

Mr. C--- H. R--Vice President

Gentlemen:
This is in reply to your letter of February 15 concerning the taxability of three products: “3Nitro Powder”, “Polystat No. 2”, and “Unistat”, which are used as growth stimulants and in controlling coccidiosis. The instructions of all three products direct the user to mix the preparations with various amounts of feed. It is our opinion that any preparation designed as a growth stimulant or a preventive of disease, which is designed to be incorporated into the feed of the animal, should itself be classified as a feed and exempt under Section 6358 of the California Sales and Use Tax Law. Sales tax reimbursement, therefore, should not be charged the customer on sales of these products. Very truly yours,

E. H. Stetson
Tax Counsel
