Please review these procedures thoroughly and ensure that this information is distributed to the 

organization’s command chain and/or management structures for awareness and training measures 

regarding CMC services provided to account holders. *Please note, failure to follow the CMC required 

procedures are measured per instance. Units that continue to have discrepancies with shipments may 

result in a “tasked suspension,” or issued a “non-negotiable account termination.” 

1.1 CMC Account Eligibility 

Organizations requesting a CMC account to send classified materiel/components marked for the CMC 

services are required to verify affiliation or registration during the application process. CMC services 

are available to NSA/CSS elements, other Intelligence Community (IC) members, and certain U.S. 

military units. There are a limited amount of US government agencies and contractors that qualify to 

send classified materiel and internal components to the Classified Materiel Conversion (CMC) facility 

for handling final disposition. To verify the items are GFE contact the Government Contracting Officer 

(CO/COR) or the program director. Section 2 provides an overview of the application process. 

2.1 Register to open a CMC account

Prior to requesting an account please check with your appropriate command structure and/or 

management chain to determine if a CIN has previously been assigned by the CMC Office. 

* Government contractors please reference required information within section 3.1. 

It’s required for a CMC account to be established before sending or delivering materiel items to the 

CMC facility. To request an account, contact the CMC office. The requesting entity would receive 

guidance to submit information on an inquiry form or an application to begin to the review process. 

Newly qualified entities will receive a CMC Policy Letter containing the assigned Customer 

Identification Number (CIN). This policy letter will also outline the responsibilities of the requesting 

entity in conjunction with the handling, protecting and disseminating the assigned CIN. 

2.2 Handling, Protecting, & Disseminating a Customer ID Number (CIN)

It is the sole responsibility of the account holders to ensure that the assigned CIN is stored, protected, 

and disseminated to all present and future assignees of their specific organizations. 

This is CMC Policy and will be enforced to keep the process efficient and cost effective. 

CMC accounts are appointed with a capitol letter followed by a string of several digits. * This is not a 

UIC or COMSEC account number. * The Customer ID is a specific identifier for all records regarding 

CMC services to disposition acceptable classified items. As an account holder, the organization is 

responsible for electing a Point of Contact (POC) that will store the Customer ID for appropriate 

recognition and provide oversight to the rest of the organization to comply with CMC procedures. 

 

*Continued on the next page

The POC is responsible for the following: (I-VII) 

I. Concerns regarding the disposition of classified or CUI NSA/CSS materiel II.

Updating information for the CMC account on record. 

Such as: organization name, location or POC’s role/rank and or contact information 

III. Maintain control of the Customer ID Number (CIN) 

IV. Developing an SOP to pair with CMC guidance 

V. Receiving approval for unlisted materiel to be sent to the CMC 

VI. Update CMC prior to any staff turnover : CMC Online Inquiry Form

VII. Ensure that only categorized or approved items, listed on the current CMC 

receipt, are transported to the CMC facility. 

2.3 Multiple Requests for the Assigned Customer ID Number (CIN)

The CMC Office maintains accounts for the Intelligence Community, a limited amount of 

government agencies, and contractor accounts for the accountability and auditing records within the 

CMC office. Therefore, this office does not hold a priority to re-issue account holders a CIN on 

multiple occasions.

Upon the discretion of the CMC office, if the entity has multiple requests on record for the disclosure 

of a previously assigned Customer Identification Number, another request could require an official 

letter on company letterhead for CMC to provide records. Address official letters from the Organization’s 

Commanding Officer (Military) or a member of the entity’s management chain (Direct or immediate 

supervisor). Note: The letter should include the Officer’s/manager’s name, phone #, and email 

address. In certain instances, the unit would have to elect a new POC, and provide name, position 

title, phone#, and email address for the account holding the discrepancy. Email or fax the official 

letter to the CMC office to begin the review process. 

Non-compliance with this policy may immobilize the disposition process for materiel/components 

sent. This might prohibit the return of the CMC receipt acknowledging disposition occurred, or the 

office could suspend CMC services indefinitely.

3.1 Required Information for Contractors To Maintain a CMC Account

Prior to transferring classified materiel items to the facility, CMC requires companies to submit a 

Contractors Approval Form (CAF) for pre-approval. A Government CO/COR or Program Director provides 

authorization, selects one appropriate statement and provides the date of signature after signing this form.

The submission of the approval form is to verify, (yet accounts are subject to further review) that:

Companies are under a current contract with the NSA/CSS, or a U.S. Intelligence Community Military 

Intelligence element that provided the contractor with Government Furnished Equipment (GFE). 

*Continued on the next page ‘ 
4

I. Contractor owned classified items (Contractor’s Acquired Property/CAP) contain direct 

NSA/CSS information. 

Once the company receives an approval to become a CMC account holder, all contractor entities are 

responsible for updating contract and account information by resubmitting the 

CAF or if the CAF on file has reached expiration (one year after the GOV’T COR signed it). 

Possession of items marked for disposition from multiple contracts requires the account holder to 

submit multiple Contractor’s Approval Forms. 

The COR signature must be updated whenever changes to the contract occur, and signatures must not 

exceed one year after submission. When submitting the CAF the bottom portion of the form must be 

completed by the Government Contracting Officer Representative (COR)/CO or Program Director. 

For further guidance for companies currently under a contract with the Intelligence Community 

please refer to the additional paperwork for contractors section 4.2.

4.1 Required CMC Documentation 

Complete the following documentation to enclose with each shipment to the CMC facility.

 

*Shipments without the required documentation are subject to return to sender. 

I. CMC Receipt for Destruction confirm the most recent version prior to sending 

II. A self-addressed envelope with a pre-paid postage * Military branches are exempt from provided 

postage. 

III. Prepare the classified materiel/component per CMC specifications in section 5. 

If multiple boxes are designated for services, review section 6.3, prior to sending any packages. 

The CMC Receipt for Destruction is the only paperwork required when shipping and/or delivering 

materiel items from Government account holders. Protect the CMC receipt and envelope from damage 

while in transit. 

Additional forms such as a Standard Form (SF) or inventory paperwork will not be accepted, and 

those additional documents will not be returned. Please use the most current pdf version of the receipt 

available for download from the CMC website. 

Previous versions of the CMC receipt will not be accepted as proper documentation after January 1, 2022. 

SF-153 forms are not required to complete the CMC process.
Printed versions of this document are not controlled. Please verify the most recent version of this document from the CMC website.

materiel not listed in the table, please contact the CMC office to inquire about possible acceptance. 

S Identifies “special burn.” This materiel holds a weight restriction referenced in section 6. 

5.2 Materiel Preparation

There are three categories for the disposition of classified materiel: Paper Pulp, Special Burn, and Solid-State 

Conversion. 

Items on Paper: Remove all fasteners larger than a staple. Separate paper documents from the plastic 

document protectors. Documents on paper are also referred to as water-soluble. This means they should break 

-down and dissolve when mixed with water. Classified items related to the IC not meeting this criterion are 

defined as “Special Burn” items; for example, CMC Customers with laminated or coated classified documents 

should contact the CMC Office for pre-approval. Record the non-water soluble materiel in the “Other Classified 

Materiel” category as “Special Burn” on a CMC receipt. An alternative method to paper pulp is shredding. The 

Media Destruction Guidance webpage displays several paper shredders the center has evaluated for use.

Hard Drive Platters: remove from server, computer tower or outer case, etc. Next, remove, all the mounting 

bracketing, the framing, and the circuit board. In addition, remove the hard drive cover. Finally, remove the 

internal platters and prepare for shipment. Previously degaussed hard drives, screws, or brackets/frames 

casing trays shall not be sent to CMC. Note: Hard drives holding NSA data are required to be returned as 

excess regardless of degaussed state; however, please prepare them as stated above, make sure the CMC 

account record notes the unit’s affiliation prior to shipping to avoid discrepancy. 

See policy manual 9-12. 

S Special Burn Items: Following are examples of classified and IC related materiel items defined as “Special 

Burn.” Instructions on how to submit those classified items to CMC are below. 

Hard Copy Media Mylar/Paper Tape, Cassettes, Microfiche, and Film. All CMC Customers with classified 

hard copy media could send it to CMC minus the outer aluminum casing and backing plate. The aluminum or 

metal removed should not be sent to the CMC facility. 

Magnetic Media: Classified Data Tapes, and Floppy Disks, etc. may send these items to CMC minus the outer 

aluminum casing and backing plate. The aluminum or metal removed should not be sent to the CMC facility. 

Optical Media Storage Cases are not accepted unless they contain classification markings ingrained on the 

case. Customers should contact CMC for further guidance/ approval for CD cases. 

Solid State Drives: allowed to be sent as is unless a battery is present. Please remove any battery prior to 

shipment.

Disk Packs: please disassemble per the manufacturer guidelines: unscrew the plastic enclosure and remove all 

platters. 

Cell Phone/Flip Phone and/or Pager Components: Remove the batteries prior to sending the item to 

CMC. Remove circuit boards from device and prepare for shipment. Note: For CMC to accept smartphone 

components see additional guidance about PCD disassembly. 

Circuit Boards: Remove frames, power supplies, plus all batteries: button type (CMOS), and lithium. Please 

do not send items removed to the CMC facility. This category includes, but is not limited to: Printed Circuit 

Boards (PCB), RAM, PCI-E, PCI-X, PCM, or motherboards from any device that will need to be disassembled. 

Computer and COMSEC Chips: To avoid mixture or loss, place computer chips in a bag, label the bag, and 

seal in the same, or if more than 40 pounds, send in a separate box. 
Printed versions of this document are not controlled. Please verify the most recent version of this document from the CMC website.

Key Storage Device Ignition Keys or Transmission Key Encryption Key (KEK) (Just the keys are 

acceptable as is) Any Key Storage Device (KSD 21, 64, etc.) will need to be disassembled. To avoid mixture or 

loss, place each component in a separate bag

Memory Cards/Sticks: Such as classified RAM Cards, MultiMedia Card (MMC), Compact Flash Drive (CF), 

Secure Digital (SD), SIM, and /or KSV 21 Fortezza Cards. Remove any batteries prior to sending. To avoid 

mixture or loss, place each component in a separate bag. 

PDAs, PCDs or MCDs such as a Blackberry, Smartphone, or Tablet, Etc. Disassembly might require 

the use of a tool known as a Pentalobe. Dissemble each device by removing the internal components that hold 

memory, classified information, and all types of batteries prior to sending a shipment to the CMC facility. 

USB Drives: remove the battery prior to sending. To avoid mixture or loss, place the thumb drives in a bag. 

Any materiel or component that is separated in a bag, please indicate the contents on the outside of the bag 

when sealed in the same (≤) 40 pound package or place all alike items in a separate box. Additional guidance is 

provided in section 6. 

Request Demilitarization (DEMIL) instructions for COMSEC gear from the unit’s governing organization/ 

Central Office of Record (COR), or the COMSEC Information Office 

After any type of battery is removed, do not send those batteries in with the classified components. Return 

those batteries to the unit’s internal hazardous material collection area. 

6.1 Shipping Items to the CMC Facility

Please remember to place all receipts and envelopes in an area inside the box that they will be 

resistant from damage by the contents or the handlers. 

CMC considers five packages or more sent at once- a large shipment. Refer to section 6.3 for 

additional guidance. 

SF-153 Forms are not required to complete the CMC Process. The provided envelopes are 

used to mail the signed and dated CMC receipt to the organization’s CMC POC/Account Holder. The 

POC would use the final receipt received to complete the standard form or other documented 

practices to have the materials removed from the unit’s property records. *Please note that SF-153 

Forms are required by your COMSEC Account Manager. Please contact the COMSEC Account 

Manager or the unit’s Central Office of Record for all COMSEC related questions.

*Note for contractors with a CMC account: in addition to including a CMC receipt with valid 

Customer ID #, and account information on record. Contractor entities are required to enclose a copy 

of the current CMC approved Contractors Approval Form (CAF) on file with the account records. 

Attach both documents with the self-addressed envelope. 

Individual packages should not exceed 40 pounds in total weight for handling purposes. Freight identified as 

“S” “Special Burn” should not exceed 1000 pounds per tri-wall container on a pallet. See table 5.1.

*Continued on the next page

 6.2 Self-Addressed Envelopes For Returning Receipts

All envelopes should be properly sized. Paper clip each envelope to the CMC receipt, etc. then place 

them with the materiel ready to be sent. Courier pre-paid envelopes for the return of the CMC 

Receipt for Destruction in a prepaid courier envelope/s: ensure to include the unit’s billing 

information for the courier to charge the account holder for the return shipment (i.e. postage and 

handling). The return label must list the mailing address that is on record with the CMC account and 

the label is affixed to the return courier envelope as required. 

First class USPS return mail is not an option for any return envelopes.

6.3 Large Mail Shipments to the CMC Facility

All individual boxes should hold a CMC receipt, CAF (if a contractor), and a self-addressed envelope in the box 

unless packages are shrink-wrapped together. 

However, CMC considers a large shipment a set of five packages or more. 

If multiple boxes are designated for services, CMC account holders should reduce the amount of receipts sent to 

one master copy -providing inventory for all components and materiel. Number all packages (1 of X), and wrap 

them together (in shrink-wrap) per the courier’s requirements. 

An alternative method would be to send all individual boxes (weight 40# or less) in one 

container (triwall). Sender should place the master CMC receipt, CAF (if a contractor), and a self-addressed 

envelope in box #1, or enclose these required items in the container on top of the individual boxes inside the 

triwall. 

Protect the CMC receipt and envelope from damage while in transit. Failure to comply with the large shipment 

(repeatedly sending five or more boxes without attempting to condense the CMC receipts to a master copy) 

policy could result in suspension of services. 

Each box stacked on a pallet sent should weigh less than or equal (≤) 40 pounds for the handlers that 

assemble and disassemble the pallets. 

Large shipments of one type of materiel (i.e. all circuit boards or all hard drives), CMC suggests a 48” 

x 40” x 36” tri-wall palletized carton to transport the components. A master CMC receipt and one selfaddressed envelope would inventory the alike materiel sent. 
Printed versions of this document are not controlled. Please verify the most recent version of this document from the CMC website. 

11

 

If a tri-wall contains different items, separate components into smaller boxes (weight = ≤ 40 pounds) 

label the contents on the top and one side panel of the box. 

Triwall carton with four sealable flaps:

Freight identified as “special burn” should not exceed 1000 pounds per palletized triwall container. 

*DCD Shipments require certain procedures and advanced notice Contact the Defense Courier station 

closest to the unit’s location for additional guidance for transferring shipments. 

As a courtesy, place two shipping labels on each box/container/case (one on top and one on a side) to assist 

couriers with moving all packages received. 

Once the CMC receipts are complete (per all guidelines in section 4), The CMC destruction facility can 

accept packages via:

I. Overnight mail/courier II. Shrink-wrapped freight 

III. DCS/DCD courier shipment IV. Crate deliveries 

6.4 Requirements For Hand carrying Materiel to the CMC facility

When delivering materiel request an appointment per section 6.5 and hand carry 2 completed copies 

of the CMC Receipt for Destruction. Self-addressed or FED EX envelops are not required because
