Are component parts a manufacturer buys to build demonstration machines exempt from sales tax under the manufacturing exemption?

Plain-English summary

A refrigeration manufacturer with a unique process built two demonstration machines that prospective clients visit to trial the product — both to test whether the process suits their needs and to work out design parameters for their own eventual machine. The manufacturer asked whether the components purchased to build these two demonstration machines were exempt from Texas sales tax.

The Comptroller explained the general "display item" exemption: a manufacturer eligible for manufacturing exemptions can buy, tax-free, a display item — one identical in size and function to other items the manufacturer holds for sale — plus the raw materials used to build it, under Rule 3.300(a)(3), as long as the item is used only to demonstrate itself (and similar items) before that specific item is eventually sold to an ultimate consumer. Any other use before that sale is a taxable "divergent use" under Rule 3.300(d)(6). But the letter then delivers the decisive caveat for this taxpayer's actual facts: if the demonstration machines are not for sale, they do not qualify for the exemption. Based on the facts described — machines built specifically for prospective clients to trial the process and aren't described as inventory ultimately sold to a customer — this points toward the exemption not applying to this manufacturer's specific demonstration machines, though the Comptroller leaves the ultimate factual determination (whether these particular machines will in fact be sold) to the taxpayer.

What this means for you

Manufacturers building demonstration or trial units

The tax-free "display item" treatment is narrower than it sounds: it only covers a unit that will itself eventually be sold to a customer, used purely for demonstration until that sale happens. If your demonstration or trial machines are permanent fixtures you never intend to sell — the way many process-demonstration setups work — the components you bought to build them are taxable, not exempt.

Businesses planning a manufacturing-exemption purchase for a display/demo unit

Before assuming the exemption applies, confirm the specific unit is genuinely intended for eventual retail sale. If it's a standing demo unit that stays in your showroom or lab indefinitely, you likely owe sales tax on it and its components.

Accountants and tax professionals

This letter is a good illustration of how a facially-favorable exemption description (the general Rule 3.300(a)(3) display-item rule) can be undercut by a single factual gap — no ultimate sale of the specific item — spelled out explicitly in the same letter.

Common questions

Q: Are components purchased to build a demonstration machine exempt from sales tax?
A: Only if the demonstration machine itself is a genuine "display item" that will ultimately be sold to a consumer, per Rule 3.300(a)(3) — and only used for demonstration until that sale.

Q: What if the demonstration machine is never intended to be sold?
A: Then it does not qualify for the exemption at all, per this letter's express caveat.

Q: What happens if an exempt display item is used for something other than demonstration?
A: That's a taxable "divergent use" under Rule 3.300(d)(6).

Q: Can other manufacturers rely on this exact letter?
A: No. This is a Texas STAR letter ruling binding on the Comptroller only for the taxpayer it addresses (34 Tex. Admin. Code Rules 3.1, 3.10); confirm whether your specific demonstration units are genuinely intended for sale with a tax professional.

Subject: Sales Tax

Dear **:

I am responding to your e-mail regarding the taxability of component parts that
are purchased to construct demonstration machines.

As a manufacturer, you are eligible for manufacturing exemptions. A display
item is a manufactured item that is identical in size and function to other
items held for sale that it represents and that is ultimately sold at retail.
See Rule 3.300(a)(3) concerning manufacturing.

The purchase of a display item and the raw materials used to make such an item
are exempt from the sales and use tax, so long as the item is used only to
demonstrate itself and the same or similar items prior to the display item
being sold to an ultimate consumer. The item may not be used for any purpose
other than demonstration or display prior to being sold. Any other use by the
manufacturer is taxable as a divergent use. See Rule 3.300(d)(6). If your
demonstration machines are not for sale, the machines do not qualify for the
exemption.

To view or down load Rule 3.300, please go to our web site address at

to the specific rule.

This opinion is rendered based on the facts presented. Other facts though
similar, may yield different results.

As a refrigeration manufacturer with a unique process, an important part of our
sales effort [almost mandatory component] we have built 2 demonstration
machines, which prospective clients come to trial their product through, both
to determine the suitability of the process and second to determine the design
parameters for their particular machine.

We ask are the components purchased to construct the demonstration machines
exempt from Texas State Sales Tax?

With thanks?
