FDA 483 Citations for Acceptance Activities Under 21 CFR 820.80

Acceptance activities are how a manufacturer proves that incoming materials, work in process and finished devices meet requirements. In fiscal year 2025, FDA investigators cited 21 CFR 820.80 on system-generated Form FDA 483s with these observations:

"Procedures for acceptance activities have not been [adequately] established," 820.80(a), 40 times
"Procedures for finished device acceptance have not been [adequately] established," 820.80(d), 32 times
"Procedures for acceptance of incoming product have not been [adequately] established," 820.80(b), 23 times
"Acceptance activities were not [documented] [maintained as part of the device history record] ...," 820.80(e), 10 times

That is 105 citations. When acceptance is weak, nonconforming components get built into devices and nonconforming devices reach patients.

What the citations mean

Examples written after "Specifically" usually describe:

Incoming components accepted on a packing slip, with no inspection, test or certificate review
Certificates of conformance accepted from suppliers who were never qualified to provide them
No defined acceptance criteria or sampling plan
In-process inspections skipped or not recorded
Finished devices released before all inspections and tests in the device master record were complete
Release not authorized by a designated person with a signature and date
Acceptance records with no identification of the inspector, the date or the equipment used
Accepted, rejected and pending material stored together without status identification

What 21 CFR 820.80 required

Under the Quality System Regulation:

General (820.80(a)): procedures for acceptance activities, including inspections, tests or other verification activities.
Receiving (820.80(b)): procedures for acceptance of incoming product. Incoming product had to be inspected, tested or otherwise verified as conforming, and acceptance or rejection had to be documented.
In-process (820.80(c)): procedures to ensure in-process product is controlled until the required inspection and tests or other verification activities are completed, or necessary approvals are received.
Final acceptance (820.80(d)): procedures to ensure each production run, lot or batch of finished devices meets acceptance criteria. Finished devices had to be held in quarantine or otherwise controlled until released, and could not be released until the activities required in the DMR were completed, the associated data and documentation were reviewed, the release was authorized by the signature of a designated individual, and the authorization was dated.
Records (820.80(e)): acceptance records had to include the activities performed, the dates, the results, the signature of the individual conducting the activities and, where appropriate, the equipment used. Records were part of the device history record.

Acceptance status had to be identified throughout manufacturing under 820.86.

What changed under QMSR

Under QMSR, in effect since February 2, 2026, acceptance requirements come from ISO 13485:2016:

Clause 7.4.3, Verification of purchased product: the organization must establish and implement inspection or other activities to ensure purchased product meets specified purchasing requirements, with the extent based on supplier evaluation results and proportionate to the risks associated with the purchased product. Records of verification must be maintained.
Clause 8.2.6, Monitoring and measurement of product: product characteristics must be monitored and measured at applicable stages according to planned arrangements and documented procedures. Evidence of conformity with acceptance criteria must be maintained, and the identity of the person authorizing release must be recorded. Where appropriate, records must identify the test equipment used. Product release and service delivery must not proceed until the planned arrangements are satisfactorily completed.
Clause 7.5.8, Identification: product status must be identified with respect to monitoring and measurement requirements throughout production, storage, installation and servicing.

The link between supplier controls and receiving inspection is now explicit. If you reduce incoming inspection for a supplier, your supplier evaluation must support it.

How to respond to the 483

FDA generally considers responses received within 15 business days of the close of the inspection before deciding on further action.

Assess product accepted without adequate verification

Identify lots received, built or released without the required acceptance. Use retained samples, testing, supplier data or field history to show conformity, or handle the product as nonconforming. Evaluate the need for a correction or removal if nonconforming devices were distributed.

Define acceptance criteria and sampling

For each component, in-process step and finished device, document what is checked, how, the acceptance criteria and the sampling plan with its statistical rationale.

Control release

Hold finished devices in quarantine or under system status until the record is reviewed and release is signed and dated by a designated person. Block shipment in the ERP or inventory system until release.

Connect receiving to supplier controls

Allow certificates of analysis or conformance in place of inspection only for suppliers whose data has been verified, and verify it periodically.

Train and verify

Train receiving, production and quality staff, and audit acceptance records after the changes.

What compliant acceptance procedures contain

Receiving inspection, including use of certificates and skip-lot criteria
In-process inspection points and hold points
Final acceptance and release authorization
Acceptance criteria and sampling plans
Acceptance status identification
Records: activity, date, result, inspector and equipment
Handling of rejected material through nonconforming product controls

Common mistakes in acceptance responses

Adding inspections without defining acceptance criteria
Using sampling plans with no statistical rationale
Accepting supplier certificates without ever confirming them
Allowing shipment before release is signed
Ignoring product already released under the old process

Example: how one response section might read

This illustrates structure only; your response must describe your own facts.

Observation 9: Procedures for acceptance of incoming product have not been adequately established. Specifically, molded housings were accepted on supplier certificates of conformance with no inspection and no verification of the supplier's data.

Response:

Correction: Housings in stock were inspected to the drawing on a stated date; all lots met requirements.
Root cause: The receiving procedure allowed certificates for all suppliers but did not require qualifying the supplier's data.
Corrective action: The procedure now requires a defined inspection plan for each part, with reduced inspection allowed only for suppliers whose certificates have been confirmed by independent testing of three consecutive lots and rechecked annually.
Extended review: Inspection plans were written for all 214 purchased parts by a stated date.
Verification: Quality will audit receiving records monthly for six months.

Frequently asked questions

Can we rely on supplier certificates of conformance?

Yes, if your supplier evaluation and verification activities support it. Under ISO 13485 clause 7.4.3, the extent of verification is based on supplier evaluation results and risk.

Who can release finished devices?

A designated person whose authority is defined in your procedures. The record must identify that person and the date.

Do we need a sampling plan for every inspection?

Where you sample, the plan must be justified. Many firms use ISO 2859-1 or ANSI/ASQ Z1.4 with a documented acceptance quality limit tied to risk.

How A.P. Lyon documents help

A.P. Lyon's Receiving and Identification of Materials Procedure, Lot Inspection Procedure and First Article Inspection Procedure cover receiving, in-process and final acceptance. The Statistical Techniques Procedure supports sampling rationale, and the Identification Procedure covers acceptance status.

Documents are editable Word and Excel files and must be adapted to your products and organization. Acceptance criteria must come from your own device specifications.
