Are anti-static grounding wristbands and anti-static floor mats/carpeting, used by circuit board manufacturing workers to prevent static electricity damage, exempt from Texas sales tax as manufacturing safety apparel?

Plain-English summary

A manufacturer of testing equipment, including circuit boards, needs its manufacturing area and workers to be free of static electricity before handling manufactured items — using either anti-static floor mats/carpeting or grounded wristbands. The taxpayer asked whether these items are taxable, and from what date.

The Comptroller split the answer by item:

• Wristbands are exempt. Tex. Tax Code § 151.318(a)(9), added by House Bill 3211, exempts safety apparel and work clothing used during actual manufacturing or processing of tangible personal property for ultimate sale, if the manufacturing process couldn't happen without it and the apparel isn't resold to the employee. The grounded wristbands qualify.
• Static mats and carpeting are taxable. These items have been taxable since October 1, 1997, the effective date of House Bill 1855, and the later 1999 House Bill 3211 safety-apparel exemption — despite covering the wristbands — did not address or change the taxability of the mats/carpeting.

What this means for you

Electronics and circuit board manufacturers

Grounded anti-static wristbands your workers wear qualify for the manufacturing safety apparel exemption and can be purchased tax-free with a properly completed exemption certificate. But budget for sales tax on anti-static floor mats and carpeting — those remain taxable regardless of how essential they are to preventing static damage during manufacturing.

Any manufacturer buying static-control equipment

Don't assume all static-control gear gets the same tax treatment just because it serves the same underlying purpose (preventing static damage during manufacturing). The Comptroller draws a real line between wearable safety apparel (potentially exempt) and facility/floor equipment (taxable), even where both are essential.

Accountants and tax professionals

This is a useful illustration that the § 151.318(a)(9) safety apparel exemption (from House Bill 3211) is narrower than "anything essential to a static-free manufacturing environment" — it's specifically apparel/work clothing worn by workers, not facility fixtures like mats and carpeting, which remain taxable under House Bill 1855's 1997 rule regardless of their manufacturing necessity.

Common questions

Q: Are anti-static wristbands used in circuit board manufacturing exempt from Texas sales tax?
A: Yes, they qualify for the safety apparel/work clothing exemption under Tex. Tax Code § 151.318(a)(9), since the manufacturing process wouldn't be possible without them.

Q: Are anti-static floor mats and carpeting exempt too?
A: No. They've been taxable since October 1, 1997 (House Bill 1855), and the later safety-apparel exemption (House Bill 3211, 1999) didn't change that.

Q: Why the different treatment if both serve the same static-prevention purpose?
A: The exemption is specifically for safety apparel/work clothing worn by employees, not for facility equipment like floor coverings — mats and carpeting fall outside that category even though they serve a similar function.

Q: Can I rely on this letter for my own manufacturing facility?
A: No. This opinion is based on the facts presented; additional or different facts may change the opinion.

Original ruling text

May 2, 2000

Dear **:

Thank you for your recent letter concerning the taxability of static guard mats
and wristbands.

Your client manufactures testing equipment, including circuit boards. It is
necessary that the manufacturing area and workers must be free of static
electricity before handling the manufactured items. They use either anti
static, mats/carpeting, or use grounded wristbands. The floor coverings and
wristbands free the area and employees from static electricity. You ask if
these items are taxable and from what date.

Response. Texas Tax Code Section 151.318 (a)(9) provides an exemption for
safety apparel and work clothing used during the actual manufacturing or
processing of tangible personal property for ultimate sale if the manufacturing
process would not be possible without its use and the apparel is not resold to
the employee. This section was added by House Bill 3211. The changes to
manufacturing exemptions in this bill are considered clarifications of statute.
The wristbands would qualify for this exemption.

The static mats and carpeting have been taxable since October 1, 1997
(effective date of House Bill 1855). House Bill 3211 (1999) did not address
the taxability of these items.
This opinion is based on the facts presented. If there are additional or
different facts, the opinion may change.

You may call me toll free at 1-800-531-5441, ext. 5-0613. The direct line is

Accounts.
