CMMC Level 1 Compliance for DoD CNC Machining Suppliers
The Cybersecurity Maturity Model Certification (CMMC) is the U.S. Department of Defense's framework for safeguarding sensitive information in the defense industrial base. CMMC Level 1 — the Foundational tier — applies to contractors and subcontractors that handle Federal Contract Information (FCI) but not Controlled Unclassified Information (CUI). Olympus Machining LLC, an ITAR-registered precision CNC machine shop in Hanover, Pennsylvania (CAGE code 9V9P0, York County), maintains practices aligned with CMMC Level 1 and FAR 52.204-21.
What CMMC Level 1 Means for a DoD Subcontractor
CMMC Level 1 is built on the 17 basic safeguarding practices defined in FAR 52.204-21. Any contractor or subcontractor processing, storing, or transmitting FCI on behalf of the federal government is contractually required to meet these practices. For a precision CNC machine shop, FCI typically includes program-related information shared by a prime contractor — purchase orders, drawings marked as FCI, schedules, and technical correspondence.
Level 1 does not address CUI. Programs that flow down CUI require Level 2 (which adds the NIST SP 800-171 control set). Olympus Machining is sized and scoped for Level 1 work and does not currently bid programs that require Level 2 / SP 800-171 certification.

SPRS Scoring Explained
The Supplier Performance Risk System (SPRS) is the DoD database that hosts contractor cybersecurity self-assessment scores. For Level 1, the assessment is a binary check: each of the 17 practices is either fully implemented (MET) or not (NOT MET). A contractor that achieves MET on all 17 practices is considered Level 1 compliant. Unlike Level 2 (NIST SP 800-171), there is no negative-point scoring at Level 1 — partial implementation does not yield partial credit.
Prime supplier-quality teams reviewing a sub in SPRS see four fields per assessment: the date of the most recent self-assessment, the scope of the assessment (enterprise, enclave, or specific contract), the result, and the date by which any Plan of Action & Milestones (POA&M) items will be closed. Olympus Machining performs the self-assessment on an enterprise scope and re-assesses annually or whenever a material change to the IT environment occurs.
Material changes that trigger a between-cycle review include: new vendor system connections (ERP, accounting), endpoint refresh that changes the firewall or EDR posture, organizational changes that affect role-based access, and any reported security event. The annual self-assessment is approved by management before submission to SPRS.
Flow-Down Clause Language for Primes
Prime contractors purchasing CNC-machined components from Olympus Machining can incorporate the following clause (or equivalent) into the purchase order to flow down FAR 52.204-21 / CMMC Level 1 requirements:
Cybersecurity Flow-Down (FAR 52.204-21 / CMMC Level 1).
Seller shall implement and maintain the basic safeguarding requirements of FAR 52.204-21 with respect to all Federal Contract Information (FCI) processed, stored, or transmitted under this Purchase Order. Seller represents that it has performed and submitted a current CMMC Level 1 self-assessment to the Supplier Performance Risk System (SPRS), and shall provide written confirmation of its current SPRS posting upon request.
Seller shall promptly notify Buyer of any cyber incident affecting FCI handled under this Purchase Order, and shall preserve relevant records for not less than ninety (90) days following discovery. Seller shall flow down equivalent requirements to any lower-tier supplier that will process, store, or transmit FCI on Seller's behalf.
This clause does not impose Controlled Unclassified Information (CUI) handling, NIST SP 800-171 / CMMC Level 2, or DFARS 252.204-7012 obligations unless separately invoked in writing by Buyer.
Olympus Machining will execute this language as-written for Level 1 subcontract work. Programs that require CUI handling, NIST SP 800-171, or DFARS 252.204-7012 should be routed to suppliers sized for that scope; we will identify scope mismatch at quote review rather than at award.
Annual Self-Assessment and SPRS Posting
Olympus Machining performs the self-assessment annually and maintains the SPRS submission as part of our supplier qualification record. A copy of our current SPRS confirmation is available to prime contractors on request.
Self-assessment is not a one-time exercise. Practice implementation is reviewed and any deficiencies are corrected before the score is submitted.
Roadmap to CMMC Level 2
CMMC Level 2 (Advanced) applies to contractors handling Controlled Unclassified Information (CUI) and requires implementation of the 110 controls defined in NIST SP 800-171. For prioritized acquisitions, Level 2 also requires a third-party assessment by a Certified Third-Party Assessor Organization (C3PAO) rather than a self-assessment.
Olympus Machining is positioned to evaluate Level 2 once our AS9100 quality system rollout is complete and the additional cybersecurity controls — audit logging, incident response, configuration management, and assessment rigor — are fully integrated. Customers with active CUI-handling programs should contact us to discuss interim arrangements and joint roadmap planning.
ITAR Registration and CAGE 9V9P0
Olympus Machining is registered with the U.S. Department of State Directorate of Defense Trade Controls (DDTC) under the International Traffic in Arms Regulations (ITAR). Our Commercial and Government Entity (CAGE) code is 9V9P0, registered to our Hanover, Pennsylvania facility. ITAR registration and CMMC Level 1 alignment together cover the baseline supplier-qualification requirements for the majority of Level-1 defense subcontracting work.
