Do I Have to Use Organic Seed?

At a glance
Yes — organic seed is the default under 7 CFR § 205.2041, the "seeds and planting stock practice standard": "the producer must use organically grown seeds, annual seedlings, and planting stock." But the rule has a practical escape valve most farmers rely on at least sometimes: when an equivalent organically produced variety is not commercially available, you may use nonorganically produced, untreated seed. The catch is that "not commercially available" is a documented determination, not a shrug.
The requirement and its exceptions
Under §205.204(a), organic seed is required except:
- (a)(1) — nonorganically produced, untreated seeds and planting stock may be used "when an equivalent organically produced variety is not commercially available." (Edible sprouts must always be from organic seed — no exception.)
- (a)(2) — nonorganically produced seeds treated with a substance on the National List may be used when an equivalent organically produced or untreated variety is not commercially available.
- (a)(5) — seeds/stock treated with prohibited substances may be used only "when the application of the materials is a requirement of Federal or State phytosanitary regulations" (e.g., a mandated treatment to cross a quarantine line).
- (a)(4) — nonorganic perennial planting stock may be sold as organic only after being "maintained under a system of organic management for a period of no less than 1 year."
The hierarchy is worth reading in order: organic first; then untreated nonorganic if no organic equivalent exists; then National-List-treated nonorganic if no organic or untreated equivalent exists; and prohibited-treated only when a regulation forces it.
What "commercially available" actually means
This is the phrase certifiers scrutinize. "Commercially available" is judged on variety, form, quantity, and quality — you can't declare organic seed unavailable just because it costs more or you'd prefer a familiar conventional variety. The test is roughly: could you have sourced an equivalent organic variety in the form and quantity you needed, at the time you needed it? Price alone doesn't make organic seed "unavailable"; a genuine absence of an equivalent variety does.
Because the determination is yours to defend, the expectation is that you searched and can show it: which organic seed sources you checked (typically at least three suppliers/catalogs), for which varieties, on what date, and what you found. That search record is exactly what an inspector asks for when they see nonorganic seed in your records.
Why inspectors care
Seed is one of the most common places a well-run organic farm slips, precisely because the commercial-availability exception feels routine. The failure mode isn't usually using nonorganic seed — that's often legitimate — it's using it without the documented search that proves organic wasn't available. No search record, no defensible exception.
How to document this on your farm
For every nonorganic seed lot you plant, you want a small paper trail: the variety, the suppliers you checked, the date of the search, the outcome, and the seed's treatment status (untreated vs National-List-treated). And you want it captured at planting, not reconstructed in February.
OrganicAssistant logs each planting with its seed source as you go, giving you the variety-and-source record that anchors a commercial-availability claim — and you can draft the seed/planting-stock section of your OSP from it rather than rebuilding a season of seed decisions from receipts.
The bottom line
Organic seed is the rule; untreated nonorganic seed is the fallback only when an equivalent organic variety isn't commercially available; and the whole exception rests on a documented search. Keep the search record and the fallback is airtight — skip it and even a legitimate substitution reads as a noncompliance.

Frequently asked questions
Do I have to use organic seed on my organic farm?
Yes, organic seed is the default requirement under the seeds and planting stock practice standard, which states the producer must use organically grown seeds, annual seedlings, and planting stock. There is a practical exception: when an equivalent organically produced variety is not commercially available, you may use nonorganically produced, untreated seed. But that unavailability has to be a documented determination, not just a preference.
Can I use non-organic seed on an organic farm?
Yes, but only under specific conditions. Nonorganically produced, untreated seed may be used when an equivalent organically produced variety is not commercially available, and seeds treated with a substance on the National List may be used when no equivalent organic or untreated variety is available. Seeds treated with prohibited substances are allowed only when the application is a requirement of Federal or State phytosanitary regulations.
What does commercially available mean for organic seed?
Commercially available is judged on variety, form, quantity, and quality. You cannot declare organic seed unavailable just because it costs more or you prefer a familiar conventional variety; price alone does not make organic seed unavailable. A genuine absence of an equivalent variety in the form and quantity you needed, at the time you needed it, is what counts.
What records do I need to justify using non-organic seed?
You need a documented search showing which organic seed sources you checked (typically at least three suppliers or catalogs), for which varieties, on what date, and what you found. For every nonorganic seed lot, keep a small paper trail including the variety, suppliers checked, date, outcome, and treatment status, captured at planting rather than reconstructed later. Without that search record, even a legitimate substitution reads as a noncompliance, and your certifier makes the final call on your operation.
