STANREC 4791 avoidance of counterfeit materiel in the defence supply chain

What it is

STANREC 4791 is a NATO Standardization Recommendation on avoiding counterfeit materiel in the defence supply chain. It is not itself a technical specification: it is a short list, naming standards that member and partner nations and NATO bodies are invited to use, without any obligation to ratify or implement them. That "invited" language is the whole point of a STANREC as distinct from a STANAG - a STANAG binds a nation through ratification and reaches a supplier through a contract clause; a STANREC only ever gets that far if a nation, or an acquiring authority acting for one, chooses to write the recommended standard into a tender or contract.

The current edition supersedes STANREC 4791, Edition 1, dated 31 August 2016. The document does not say what changed between the two editions.

What it recommends

The recommendation names five standards. Leading the list is AQAP-2021, Edition A, NATO's own Allied Quality Assurance Publication for counterfeit avoidance. Alongside it: SAE AS 5553 Rev A, on avoiding, detecting, mitigating and disposing of fraudulent or counterfeit electronic parts; IEC 62239-1:2018 Part 1, on preparing and maintaining an electronic components management plan for avionics; SAE AS6174 Rev A, on assuring the acquisition of authentic and conforming materiel; and UK DEF STAN 05-135, the UK's own standard on avoiding counterfeit materiel. A sixth document, IEC 62402:2019 on obsolescence management, is named separately as "other related" rather than recommended outright - worth noting, because it is easy to read the two lists as one.

Beyond naming these standards, STANREC 4791 also points to guidance NATO has produced for acquiring organisations: background on the risk counterfeit material poses, a worked example of counterfeit-avoidance contractual wording, guidance for running acquisition quality assurance activities against that risk, and an assessment of the standards and specifications suppliers may be referred to. That guidance, not this four-page recommendation, is where the practical detail sits.

Who it addresses, and when it starts to matter

The recommendation itself is addressed to member and partner nations and NATO bodies, who are asked to feed back to the NATO Standardization Office on how they use the standards it covers. It reaches an acquiring organisation once that organisation decides which of the five standards fits its programme, and it reaches a supplier only once one of those standards is written into a tender or a contract - STANREC 4791 creates no direct duty of its own. Review of the recommendation happens in accordance with AAP-03, with the outcome recorded in the NATO Standardization Document Database rather than communicated to any supplier.

How it is checked

There is no certification, audit or inspection built into STANREC 4791, and the document names none. Any assessment mechanism belongs to whichever standard a contract actually invokes - most likely AQAP-2021, which carries its own government quality assurance arrangements - not to this recommendation. A reader looking for how they are checked against STANREC 4791 itself is looking in the wrong document.
