Certifications, Registrations & Lab Testing
No vague "premium quality" claims. Every credential on this page comes with a registration number, a batch-specific COA, or a public database where you can verify it yourself.
FDA Food Facility Registration
Registration Number
13416123802
Chestnut Supply operates as an FDA-registered food facility under the Federal Food, Drug, and Cosmetic Act and the Bioterrorism Act.
What this means — and doesn't
FDA registration is a legal requirement for facilities that manufacture, process, pack, or hold food for US consumption. It is not an FDA approval, endorsement, or certification of any product. We state this plainly because suppliers who imply otherwise are misleading you.

Thymoquinone content varies by lot; typical range 1.2–2.4% (current stock is standard grade). New to TQ numbers? Read our thymoquinone buyer's guide.

Certification & Testing FAQ
Is Chestnut Supply an FDA-registered facility?
Yes. Chestnut Supply operates under FDA Food Facility Registration number 13416123802. Note that FDA registration is a legal requirement for food facilities and does not mean FDA approval or endorsement of any product.
Is Chestnut Supply USDA certified organic?
No. Chestnut Supply is not itself a USDA certified organic operation. Our source manufacturer in Turkey holds USDA NOP organic certification (certified by ETKO, NOP Operation ID 9962925001, Handling scope). Organic-designated lots are available on request and confirmed on a per-lot basis with supporting documentation.
Is every batch of your black seed oil organic?
No. Standard inventory is conventional cold-pressed oil. Organic-designated lots are sourced under our manufacturer's NOP Handling-scope certification and are confirmed per lot, with lot-specific paperwork, before ordering.
Do you provide a Certificate of Analysis (COA)?
Yes. Every batch is tested by an independent third-party laboratory for thymoquinone content and fatty acid profile. A batch-specific COA is available for every order, and the full third-party analysis report is shared with qualified buyers on request.
How can I verify your credentials myself?
The source manufacturer's organic certification can be verified directly in the USDA Organic Integrity Database under NOP Operation ID 9962925001. FDA registration status can be confirmed with our registration number 13416123802 through an FDA registration verification request. Batch COAs are matched to lot numbers you can check against your delivered goods.
