Latest reviewed evidence
Kew accepts Azadirachta indica A.Juss. in Meliaceae. A May 2025 BIS draft for neem extract concentrate containing azadirachtin proposes maximums of 1.0 percent moisture, 1.0 percent material insoluble in acetone and 0.5 percent acidity as sulfuric acid or alkalinity as sodium hydroxide, while requiring declared nominal azadirachtin content and nil aflatoxin. The document is explicitly a draft for comments, not proof of a lot or a current certification. EPA separately identifies azadirachtin and clarified hydrophobic extract of neem oil, so Atlas does not treat raw seed, oil, clarified oil and active-ingredient concentrate as synonyms.

Azadirachta indica identity comes before a neem specification
Kew accepts Azadirachta indica A.Juss. in the mahogany family, Meliaceae, and records a native range from Assam to Indo-China with broad introductions elsewhere. A common name, seller location or botanical-use claim does not prove species, plant part or production origin. Atlas retains the scientific identity evidence, harvest and processing origin, plant part and lot chain before comparing material sold as neem.
Seed, kernel, leaf, cake, oil and extract are different products
BIS maintains a specification for neem kernel oil and depulped neem seed oil, while its May 2025 draft for neem extract concentrate states that the extract is derived from kernel or depulped seed and records nominal azadirachtin content. EPA separately identifies azadirachtin and clarified hydrophobic extract of neem oil and explains that alcohol treatment separates virtually all azadirachtin and related substances from the remaining oil. Atlas therefore preserves plant part, depulping or decortication, pressing or extraction method, clarification, solvent or carrier system, active-content basis and residual cake instead of using neem, neem oil and azadirachtin as substitutes.
Regulated pesticide identity is not inferred from raw botanical material
A raw leaf, seed, kernel, oil or cake lot is not automatically a registered pesticide active ingredient or authorized formulation. EPA assigns separate identifiers to azadirachtin and clarified hydrophobic extract of neem oil. India's dated pesticide-formulation list distinguishes neem-seed-kernel-based, neem-oil-based and extract-concentrate formulations at stated azadirachtin levels. Atlas records jurisdiction, product authorization, formulation, label, manufacturer, batch and verified active-content test separately; a historical listing does not prove current authorization in a destination market.
Planting seed requires current viability and phytosanitary evidence
FAO's review documents rapid and condition-dependent loss of neem-seed germination in historic trials, including under 5 percent after twelve weeks in one room-temperature and refrigerated comparison and zero after twenty-four weeks in another trial. The same review reports exceptional longer-storage observations and warns that collection and handling histories were incomplete, so no single longevity figure is universal. APHIS states that import requirements vary by exact commodity and origin and must be checked in ACIR. Atlas retains harvest date, fruit maturity, collection method, pulping, drying, moisture, storage time and conditions, representative germination test, treatment, origin and destination permit or phytosanitary evidence.
A laboratory threshold or regulatory listing does not establish a delivered neem price
A botanical identity, BIS draft threshold, EPA identifier, formulation registration or seed-viability study does not establish an offered lot's grade, active content, availability, transaction value or delivered cost. A physical comparison still needs permitted current observations for the exact plant part and processed form, intended use, origin, lot test results, extraction basis, regulatory disposition, package, quantity, currency, Incoterm, destination, delivery window, route costs and information vintage. Atlas withholds a physical estimate when those observations or usage rights are missing.
