Was lumber used for cargo platforms, self-shoring, and blocking aboard seagoing vessels exempt as a watercraft component?

Short answer No. California treated lumber installed to increase cargo capacity and prevent heavy cargo from shifting like dunnage installed on freight cars, not as exempt watercraft property. Counsel recommended denying the petition in full.

Disclaimer: This is a February 5, 1957 California State Board of Equalization associate-tax-counsel recommendation on a redacted petition, published by CDTFA as support for a sales and use tax annotation. It addresses lumber used for cargo capacity and stability and a separate unverified cartage claim. The letter says official Board action would follow, so it is not itself the Board's final notice.

Plain-English summary

A vessel operator used lumber to erect platforms, self-shoring, and blocking on seagoing vessels. The purpose was to increase cargo capacity and keep heavy cargo from shifting.

California concluded that the lumber did not qualify under the watercraft exemption. It compared the installation with dunnage used on freight cars rather than property becoming part of the vessel.

The petitioner also challenged cartage charges in the taxable measure but did not provide requested documentation. Counsel recommended no adjustment and denial of the petition in full.

What this means for you

Cargo contractors, vessel operators, and tax advisers

Temporary lumber serving the needs of a particular cargo load may be treated as taxable dunnage. Preserve invoices and requested support for every separate audit adjustment, including freight or cartage claims.

Q: What function did the lumber serve?

This is to advise you that we have given careful considera­ tion to the data whirh was .~eveloped at the meeting attended by you, Mr. '.. .,,.., _ ___ . 3 Mr. !. __. r and the representatives of this Board, Mr. Roberti and Mr. Swanson. It is our opinion that the sales of lumber used by the

We feel that you have been correctly advised that this installation of lumber is com­ parable to that of the installation of dunnage on freight cars.

(J

Since we have received no reply to our letter of October 19 in which we requested documentary verification of petition­ er's claim that the measure of tax improperly included cartage charges, we can only recommend that no adjustment be made because of this item. We shall, therefore, recommend to the Board that the peti­ tion be denied in its entirety and that the unpaid amount is due. You will receive notice of the Board's official action in due course. Very truly yours,
