FDA 510(k) Step-by-Step Guide for Turkish Exporters
What Is the 510(k) Pathway?
The 510(k) is a premarket notification submitted to the FDA demonstrating that a new device is 'substantially equivalent' to a legally marketed predicate device. It is the most common FDA clearance pathway, covering approximately 85% of novel medical devices entering the US market. 510(k) is appropriate for Class II devices (and some Class I devices requiring premarket notification).
Substantial equivalence means the new device: (1) has the same intended use as the predicate, AND (2) has the same or different technological characteristics where any differences do not raise new safety/effectiveness questions.
510(k) is distinct from PMA (Premarket Approval — Class III, most complex devices requiring clinical trials) and De Novo (novel devices with no predicate but low-to-moderate risk). This guide focuses on the 510(k) pathway.
Part 02Who Must Submit a 510(k)?
- Any medical device manufacturer (US or foreign) who intends to introduce a Class II device to the US market
- Turkish manufacturers must appoint a US Agent — a person or company physically located in the USA who acts as the FDA's point of contact. The US Agent is not a legal importer; the importer is the party who brings goods into the USA.
- Foreign manufacturers must also register their establishment with FDA (FDA establishment registration, annual renewal, Form FDA 2891) and list their devices (Form FDA 3881)
- The 510(k) is submitted by the device owner (Turkish manufacturer) through an electronic submission portal (eSTAR — electronic Submission Template and Resource)
Predicate Selection — The Most Critical Decision
Predicate selection determines whether your 510(k) is approved or refused. The predicate must be:
- A legally marketed device (prior to 28 May 1976, or previously cleared via 510(k) or De Novo)
- Not currently subject to a PMA requirement
- Of the same device type and intended use as your device
How to find predicates: FDA's 510(k) database (accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm) is publicly searchable. Search by product code, device classification name, or competing manufacturer. A product code (3-letter FDA code) is the most efficient search parameter — it identifies your device's regulatory classification.
Split predicate strategy: It is permissible to cite two predicates — one for intended use and one for technological features. This is called a 'split predicate' and is commonly used when no single device fully matches your design.
Part 04510(k) Submission Content Requirements
| Section | Content |
|---|---|
| Cover Letter | Summary of submission, device name, product code, submitter details, US Agent info |
| Device Description | Complete technical description, materials, dimensions, components, accessories |
| Predicate Comparison | Side-by-side comparison of intended use and technological characteristics |
| Performance Testing | Bench testing data demonstrating equivalence — typically referencing FDA-recognised consensus standards (ASTM, AAMI, ISO) |
| Biocompatibility | ISO 10993-1 assessment (required even for CE-certified devices) |
| Sterilisation | Sterilisation method validation (ISO 11135, 11137, 17665) |
| Software (if applicable) | Software documentation per FDA guidance — IEC 62304 alignment accepted |
| Substantial Equivalence Summary | 510(k) Summary or 510(k) Statement |
| Labelling | Proposed US labelling — must comply with 21 CFR Part 801 |
| Risk Management | Risk analysis per ISO 14971 (FDA recognises this standard) |
Timeline and Costs
- FDA target: 90 calendar days from acceptance to decision (rarely achieved for complex submissions)
- Actual average: 120–150 days for standard 510(k)
- Additional Informations (AI) request: adds 90 days per AI cycle — a well-prepared submission minimises AI cycles
- Total realistic timeline (from preparation start to clearance): 12–18 months
- FDA user fee (FY2026): USD 22,248 for standard 510(k) (small businesses may qualify for 50% reduction)
- Regulatory consulting / preparation: USD 30,000–80,000 depending on complexity
- Performance testing: USD 15,000–50,000 depending on test programme
- US Agent: USD 1,000–5,000/year
- Total investment estimate: USD 70,000–180,000
How CE Documentation Helps (and Where It Falls Short)
Turkish manufacturers with CE certification have a significant head start on 510(k) preparation:
- ISO 10993 biocompatibility data — directly usable in 510(k)
- ISO 14971 risk management file — FDA recognises ISO 14971; risk analysis can be reused
- Performance testing data — if tests were conducted to FDA-recognised consensus standards (ASTM, ISO), results are directly usable
- IEC 62304 software documentation — FDA-recognised; directly usable for SaMD submissions
Where CE preparation doesn't transfer:
- Clinical evaluation report (CER) — FDA does not accept EU-format CERs; US clinical data or literature review in FDA format is required
- Labelling — must be reformatted to 21 CFR Part 801 requirements (different from EU MDR Annex I §23)
- 510(k) Summary — a specific FDA document format with no EU equivalent
