CMMC Level 1 · Plastics & rubber

CMMC Level 1 for plastics & rubber products manufacturers

Injection molders, rubber fabricators, and seal and gasket makers supplying the defense supply chain sit at CMMC Level 1 for build to print work. POs, drawings, material certs, and delivery records are Federal Contract Information (FCI). CUI is uncommon and arrives only with a marked technical data package under a DFARS 252.204-7012 flow-down.

Overview

If you mold, extrude, or fabricate plastic and rubber parts, seals, gaskets, hoses, or components for defense and federal supply, your purchase orders, drawings, material certifications, and delivery records are Federal Contract Information. That triggers FAR 52.204-21 and a CMMC Level 1 self-assessment with an annual SPRS affirmation.

Plastics and rubber work is almost entirely build to print from unmarked drawings, which keeps it at Level 1. A specific job reaches Level 2 only when a prime flows down DFARS 252.204-7012 and sends marked technical data, which is uncommon for commodity molded and fabricated parts.

These shops typically run an ERP or quality system, a couple of office PCs, and email. Level 1 covers those systems, which means named accounts, MFA, controlled access to drawings, and a clear boundary.

Typical contracts you'll see

  • Subcontracts to defense primes for molded and fabricated parts
  • Seal, gasket, and hose supply for military equipment
  • DLA buys for plastic and rubber components
  • Build to print molding for ground, air, and sea systems
  • Replacement parts and consumables under federal supply schedules

What FCI actually looks like for you

Anything below is Federal Contract Information and triggers FAR 52.204-21. None of it is CUI on its own.

Purchase orders and statements of work from a prime or DLA
Part drawings and specifications that are not marked CUI
Material certifications and first article inspection records
Delivery schedules, packing slips, and DD-250 acceptance documents
Nonconformance reports and corrective action requests

Common pitfalls in this industry

  • Emailing drawings and POs from personal accounts, which fails FAR 52.204-21 (b)(1)(i) and (iii).
  • Running the quality or ERP system on one shared login, which fails (b)(1)(i) and (ii).
  • Storing drawings on an open share that every contractor can read, which fails (b)(1)(iii).
  • Assuming commodity parts are out of scope. The FCI in the paperwork is what triggers CMMC.
  • Missing a rare -7012 flow-down on a specific program.
  • Skipping the annual SPRS affirmation.

Your Level 1 action plan

  1. 01Confirm with each prime in writing that no marked CUI has been or will be flowed down for your parts.
  2. 02Inventory the systems that hold FCI: ERP or quality system, office PCs, the file share, email, and backups.
  3. 03Move drawing and PO exchange onto a paid Microsoft 365 or Google Workspace tenant with MFA enforced.
  4. 04Give each user a named account and set drawing access to least privilege.
  5. 05Separate program systems from public web browsing and the company website.
  6. 06Write a short boundary description naming the systems that hold FCI and who can access them.
  7. 07Run the 15 practice self-assessment, capture evidence, then have a senior official affirm the score in SPRS and set the annual reminder.

Frequently asked questions

Q.We just mold plastic parts to a print. Do we really need CMMC?

Yes, once you hold a federal contract or subcontract. The purchase orders, drawings, material certs, and delivery records are Federal Contract Information, and FAR 52.204-21 applies to the systems that hold them. The 15 practices are basic protections on your office systems and email.

Q.Would a molding job ever be Level 2?

Only if a prime flows down DFARS 252.204-7012 and sends technical data explicitly marked as CUI or Controlled Technical Information, which is uncommon for commodity molded and fabricated parts. Standard build to print work is Level 1.

Q.Is our quality system in scope?

Yes, if it holds POs, drawings, or inspection records that are FCI. The quality system, the office PCs, and the laptops that reach them are part of your Level 1 boundary and must meet the 15 practices: named accounts, MFA, access limited to authorized users, antivirus, and patching.

Q.Do I need an SSP at Level 1?

No. Level 1 does not require a System Security Plan under 32 CFR Part 170. You need evidence the 15 practices are met for the systems that handle FCI, plus a short boundary description and a current list of authorized users.
