No standards are available for home gardens. You can be as strict, or not, as you prefer.

I sell some of my produce at a little stand by my driveway. I wondered if I can call it "organic", which it is, unless the kitchen scraps mean it's not...

All compost is organic. Compost that contains kitchen scraps, even from sources that did not grow them organically, would still be organic.

As long as your sales do not exceed something like $5,000.00 per year you can label what y9ou sell as organic without being certified. Just be ready to answer questions with something more than "I don't use chemicals" because every organic grower does.

Thanks kimmq.

If cows must be fed an all-organic diet (no GMOs, grown without the use of synthetic fertilizers, pesticides and herbicides) so their produce can be called "organic" ... why should it be any different for a compost heap?

If digesting something in a microbe-filled pile can make it "organic" for growing, why doesn't digesting something in a microbe-filled rumen make it "organic" for dairy?

Compost may not be organic per OMRI.

*******Compost that
contains the following is prohibited: sewage sludge, synthetically fortified
compost starter, glossy paper, and materials containing colored ink. Compost is
prohibited if it contributes to the contamination of crops, soil, or water by
plant nutrients, pathogenic organisms, heavy metals, or residues of prohibited
substances. See also MICROBIAL PRODUCTS listings for information on compost
starters, SEWAGE SLUDGE, and MUSHROOM COMPOST. See Glossary for definition of
"compost."*****

There is no dollar amount involved. Regardless of the size of your sales operation, you cannot technically call your produce "organic" unless it (and your growing property) has received government certification. There is an interim level - "Certified Naturally Grown" - that denotes food that was grown using the same standards as
those for organic but not on a farm officially certified by the USDA's
National Organic Program. Some farmers have criticized the cost and
process required to participate in the USDA's program, so this label
represents an alternative, non-governmental certification system,
wherein fellow farmers act as inspectors, with the nonprofit
organization Certified Naturally Grown
acting as the administrator. The "Certified Naturally Grown" seal
indicates an official review process held to the same standards as USDA
Organic.

Or - and this far and away the simplest method - just label your sale produce as "naturally grown using organic methods".
