Were modular radio-frequency anechoic chambers bolted together and to a building floor machinery and equipment?

Short answer No. They were materials because they were not readily removable as units, and providing a room for manufacturing did not make the room itself manufacturing machinery.

Currency note: this ruling is from 1965
Subsequent statutory amendments, regulation changes, court decisions, or later rulings may have changed the analysis. Treat this page as historical context, not current tax advice. Verify current law before relying on any specific rule, rate, or position mentioned here.
Disclaimer: This November 12, 1965 memorandum applies historical Ruling 12 to radio-frequency-shielded chambers assembled from prefabricated panels and bolted together and to an existing building's floor. The opinion depends on the submitted construction and attachment description and compares an earlier special-enclosure memorandum not reproduced here. CDTFA says statutory law controls if it conflicts with an annotation. Panel design, removal as a complete unit, attachment, installed purpose, manufacturing function, and current Regulation 1521 can change the result.

Plain-English summary

The reviewed anechoic chambers were radio-frequency-shielded rooms assembled from prefabricated panels. The panels were bolted together and the completed chambers were bolted to an existing building's floor.

Although workers could disassemble the panels, the chambers were not readily removable as complete units. And even if manufacturing occurred inside them, the rooms were not installed to perform the manufacturing operation themselves.

The memorandum therefore classified the chamber units as construction materials rather than machinery and equipment under historical Ruling 12.

Common questions

Did modular panel construction make the chambers machinery and equipment?

No.

Could they be removed?

They could be disassembled, but were not readily removable as units.

Did manufacturing inside the chamber control?

No. A room containing manufacturing activity was not itself manufacturing machinery.

STATE OF CALIFORNIA

565.0340

STATE BOARD OF EQUALIZATION
November 12, 1965
Mr. ______,

I have reviewed the information which has been submitted in connection with the petition for redetermination filed by "E". Our auditors have taken the position that the modular anechoic chamber units assembled and installed by "E" constitute materials and not machinery and equipment under Sales and Use Taxes Ruling 12. From the information which has been submitted, it appears that these units are substantially similar, in construction and manner of attachment, as the "special enclosures" furnished to the "N" and installed at San Diego, to which we referred in our memo of January 7, 1964. As indicated in "E"'s literature, the anechoic chamber units are radio frequency-shielded chambers, assembled from prefabricated panels, which are bolted together and to the floor of an existing building. If our understanding is correct, although each unit is bolted together and can be disassembled by removing the bolts, nevertheless it does not appear that it is "readily removable as a unit". Further, to paraphrase our statement regarding the "special enclosures", although manufacturing operations may be performed inside the chamber units, it is our opinion that they are not installed "for the purpose of performing a manufacturing operation" as that term is used in Ruling 12. Manufacturing operations could be performed in any room in a factory building, but the Board has never considered that fact as determinative of the status of a room as "machinery and equipment". In view of the foregoing, it is my opinion that the modular anechoic chamber units assembled and installed by "E" constitute materials under Sales and Use Taxes Ruling 12 and not "machinery and equipment".
