Frequently Asked Questions

Does the type of aggregate used in making the unit matter for determining inclusion?
No. If the aggregates are mixed with a cementitious binding material and the resulting unit is made on a block machine and conforms to other definitions, those units made with a wide range of aggregates should be included. A non-exhaustive list of aggregates includes: natural aggregates (calcareous, siliceous, limestone, granite, etc), manufactured lightweight aggregates (expanded clay, shale, slate, bottom ash, etc.), manufactured aggregates (polystyrene, etc.), recycled materials, etc.
Does the type of cementitious material used in making the unit matter for determining inclusion?
No. Portland cement variations might be most common, but units made with alternative cement replacement binders should be included also.
Should units intended to be laid with robotic installations be included?
Yes – assuming that they meet other determining requirements.
Should concrete brick be reported?
Yes – if they are “architectural,” meaning that they are intended to be exposed in the masonry wall (which would typically mean that they have integral coloring) and they meet the standard block criteria that they: 1) have an actual bed depth of 3 inches or greater, 2) are manufactured on a block machine, 3) are made of dry-cast concrete, and 4) are suitable for use in concrete masonry construction.
Should concrete lintels be reported?
U-shaped and knock-out concrete block lintel units (typically 8 to 24 inches in length), SHOULD be reported (see Included Products). These units are simply a type of concrete block that meets all of the definitions of a concrete masonry unit within this program. However, those concrete products that are designed to span and entire opening (typically greater than 24 inches, and typically reinforced) are specifically excluded from this program, regardless of whether they are made of wet-cast or dry-cast concrete.
Are proprietary units included, or only standard, commodity units?
All concrete masonry units, including those licensed and patented, are included if they meet the governing definitions.
Are fly-ash block included?
Yes – this product includes binding mediums referenced in the definition of dry-cast concrete.
Are units made on a big board machine included?
Yes – if those units meet the other qualifications (made for use in masonry construction; width of 3 inches or greater). The definition of "block machine" is such that it would encompass most big-board machines.
Are non-loadbearing units included, or is the program limited to structural block?
The definitions do not distinguish between loadbearing, non-loadbearing, veneer, or other applications. The key factor is whether the units are manufactured and sold primarily for use in “masonry construction.” Therefore, non-loadbearing units used in masonry are included.
Are there certain ASTM unit specifications that apply to included and excluded units?

While ASTM standards are not referenced in the definitions, they can provide a reasonable guide to assist in determining inclusion and exclusion.

In general, units complying with the following specs are included: C 90 Loadbearing Concrete Masonry Units, C129 Nonloadbearing Concrete Masonry Units, C744 Prefaced Concrete Units, C1634 Concrete Facing Brick and Other Concrete Masonry Facing Units, C1790 Fly Ash Facing Brick.

In general, units complying with the following specs are excluded: C55 Concrete Building Brick, C139 Catch Basin and Manhole Units, C216 Facing Brick (Solid Masonry Units Made from Clay or Shale), C652 Hollow Brick (Hollow Masonry Units Made from Clay or Shale), C936 Solid Concrete Interlocking Paving Units, C1372 Dry-Cast Segmental Retaining Wall Units, C1623 Manufactured Concrete Masonry Lintels, C1670 Adhered Manufactured Stone Masonry Veneer Units, C1691 Unreinforced Autoclaved Aerated (AAC) Concrete Masonry Units, C1782 Segmental Concrete Paving Slab, C1884 Concrete Ballast Block, C1877 Adhered Concrete Masonry Units.

Are units made in or shipped to countries outside of the United States assessed?
No. Only those units made and sold within the U.S. are included. Units are excluded if they are manufactured outside of the U.S. For the purposes of this program, those units made in U.S. territories (American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands) are excluded.

Straight Facts about Concrete Masonry Checkoff Assessments

After more than a decade of work by countless block producers and allied industry leaders, the Concrete Masonry Checkoff (CMC) is now underway. On April 1, 2023 assessments officially began, paving the way for game-changing programs designed to win back lost market share and drive new demand for block.
  • When did assessments begin?

    The start date of assessments was April 1, 2023. The checkoff rate is a penny per block sold and only at the first point of sale. Assessments are due 60 days following the end of each quarter.
  • How will I pay into the checkoff?

    Assessments will be remitted to a blind trust to ensure absolute confidentiality in all sales information and remittance amounts. Producers will not be invoiced, but the CMC Board will provide two payment options – ACH and check. A form will also be provided with details of products included in the checkoff and will include all necessary information for calculating and submitting payment. In time, assessments will be randomly audited by an independent third party.

    As a reminder, this is a mandatory checkoff, ensuring all producers contribute at an equal rate working together as an industry to drive preference and demand for concrete masonry products.

  • How do we show documentation of the checkoff when a sale is made?

    Legislation requires that each invoice, bill of sale and/or receipt for eligible block identify the total amount of the checkoff assessment for that purchase. The approved verbiage is:

    "1 cents per masonry unit goes to the Concrete Masonry Checkoff Board pursuant to the Concrete Masonry Products Research, Education, and Promotion Act of 2018".

    You may use other language in addition to or in lieu of the safe harbor language, if you choose, but the approved language will assure that you comply with the statute.

  • Can I pass the penny assessment on to my customers?

    It is up to each producer to decide how you will handle the checkoff on your actual product sales. You may elect to build it into the price or reflect it as a line-item fee on invoices. But it is imperative you do not discuss your plan with any other company.

  • Where can I get more information about assessments?

    The CMC Board chose a later start date for assessments to allow ample time for companies to put processes and any needed software into place and to ensure the checkoff can provide any needed resources to support producers. the Board is in the process of creating additional resources for producers, including a help line, and a series of learning session.
