Purpose of this retained page: This is a documentation checklist for customers evaluating calcium lignosulfonate in certified organic crop production. For the regulatory explanation, exact-grade data and application-rate status, first read Calcium Lignosulfonate in Organic Crops: Compliance Guide.
Organic eligibility is a dossier decision
Neither a natural feedstock nor a CAS number automatically makes a commercial product acceptable in every organic program. The decision depends on the governing standard, permitted function, manufacturing process, impurities, intentionally added ingredients, formulation, label claims and approval by the operation’s certifying agent.
The USDA National Organic Program lists lignin sulfonate under a restricted annotation for use as a chelating agent or dust suppressant in crop or soil amendments. USDA also states that all substances used on organic operations must be approved by the operation’s certifying agent before use. See the USDA lignin-sulfonate review page and the USDA National List guidance.
Core supplier dossier
| Document / information | What it should identify | Why the reviewer needs it |
|---|---|---|
| Current TDS | Exact product name/code, revision, physical form and current analytical values | Confirms the commercial material being evaluated |
| Current MSDS/SDS | Identity, composition disclosure, hazards, handling, storage and transport information | Supports substance and safety review; it is not proof of organic approval |
| Signed batch COA | Lot, dates, methods, specification limits and actual results | Distinguishes batch data from illustrative templates |
| Manufacturing-process statement | Feedstock, pulping/recovery route, neutralization, purification, modification and drying | Supports synthetic/nonsynthetic and process evaluation |
| Full ingredient statement | All intentionally added ingredients, carriers, preservatives, processing aids and percentages | Approval applies to the complete product, not just the named active material |
| Impurity / contaminant statement | Relevant metals, residual processing chemicals and market-required limits | Supports product and jurisdiction-specific risk assessment |
| Intended-use statement | Chelating agent, dust suppressant or other proposed function; crop/soil route and rate basis | Allows comparison with the applicable annotation and label |
| Label and claims | Directions, nutrient declarations, crop claims, cautions and markets | Prevents approval of one function from being expanded into unreviewed claims |
Exact Green Agrochem grade under review
Where the proposed material is Calcium Lignosulfonate — Agri-Grade, GAC-CaLS-AGRI, TDS Rev. 2.0, the application should use the matching MSDS/SDS and shipment COA for that same product code. Do not substitute documents for food, feed, feed-binder, construction, dust-control, light-colour or general calcium grades.
The complete product-data table—including pH 4–7, dry matter 95% min, water-insoluble matter 0.2% max and lignosulphonate content 60% min—is maintained on the linked compliance guide rather than duplicated here. Those figures characterize the grade; they do not certify it for a market or use.
Application-rate documentation
GAC-CaLS-AGRI TDS Rev. 2.0 lists 0.1–1% for wetting/spreader-sticker evaluation and a 1–3% solution for soil-conditioner evaluation. In an organic-input submission these must remain supplier-recommended starting trial ranges, with the percentage basis confirmed in writing. They are not an approval, legal maximum, universal field rate or performance guarantee.
Older values such as 0.5–2% soil incorporation, 5–10% soil solution, 0.1–0.5% foliar spray and general dust-control rates are not supported by the current exact-grade TDS. If a customer needs them, recover the original grade, source, basis and test report before inclusion in a dossier.
Claims that require separate evidence
- Guaranteed improvement of soil structure, water retention, microbial activity or nutrient uptake
- Correction of calcium deficiency or increased crop yield and quality
- Reduced fertilizer, irrigation, runoff, erosion or pesticide requirement
- Non-toxic, heavy-metal-free, residue-free, fully biodegradable or universally environmentally safe
- Compliance with USDA, EU or another organic program without product- and use-specific approval
Each statement needs an appropriate source and scope. Product composition comes from current supplier documents; agronomic results require defined trials; safety comes from the exact SDS and supporting studies; organic eligibility comes from the relevant certifier or input-review decision.
Customer submission workflow
- Confirm the destination country, organic standard, certifier and intended function.
- Freeze the exact product code and commercial formulation.
- Collect the current supplier dossier and resolve conflicts between revisions.
- Prepare the proposed label, rate basis and use instructions.
- Submit the complete package before purchase or field use and retain the written decision.
- Re-review after any manufacturing, supplier, formulation, label or regulatory change.
