A cocoa powder technical data sheet arrives as a page of numbers, and a safety data sheet arrives as sixteen sections nobody reads until a customer's EHS team asks for them. Together they decide whether your quality team releases the first container or sends it to quarantine. What matters is not that the documents exist, but that the figures are specific to the grade you buy, tested by a stated method, and consistent with the certificate of analysis travelling with each lot.
This guide covers what each document should contain, which figures deserve independent verification, and how to recognise a spec sheet assembled from another supplier's brochure.
A technical data sheet declares the product being sold: grade, plant, and a guaranteed range rather than an approximation for every parameter that affects your process.
Parameter | What a usable TDS shows | Why it matters |
|---|---|---|
Fat content | 10–12% or 4–8%, as a guaranteed range with test method | Drives colour strength, mouthfeel and cocoa dose per batch |
pH | Natural 5.0–6.0; lightly alkalised 6.8–7.5; heavily 7.8–8.5 and above | Sets flavour, solubility and reaction with leavening agents |
Moisture | 5.0% maximum, typically 2–5% | High moisture shortens shelf life and encourages caking |
Fineness | 99.5% minimum through 200 mesh (75 µm), sieve method named | Controls dispersion in drinks and specking in baked goods |
Bulk density | Usually 0.45–0.60 g/cm³ loose; lower for heavily alkalised grades | Affects hopper flow, dusting and volume-based dosing |
Free fatty acid | 1.0% maximum as oleic acid | Early indicator of fat hydrolysis and stale flavour |
Microbiology | Plate count, yeast, mould, coliforms, Salmonella — each with a limit and sample size | "Conforms to standard" is not a specification your QA can release against |
Contaminants | Lead, cadmium, ochratoxin A and pesticides in mg/kg or µg/kg | Limits differ by market and have been tightened repeatedly |
Packaging and shelf life | 25 kg kraft bags with PE liner or 500–1000 kg FIBC; 24 months at ≤25 °C | Determines storage plan, pallet count and container payload |
"Fat 10–12%" is a guarantee; "fat approx. 11%" is not. Ask for the method too: solvent extraction and NMR differ, and half a point matters when your recipe sits on the lower bound. Confirm whether the figure is as-is or on dry matter.
Alkalisation is a process, so pH is the only reliable description of it. Two powders labelled "lightly alkalised" from different plants can sit a full point apart, which shifts flavour and colour visibly. If your system is pH-sensitive, buy against a tested pH range, not a marketing term.
These are the quiet shelf-life killers. Moisture above roughly 5% encourages caking and gives mould a foothold; free fatty acid creeps up during poor storage and shows later as a soapy note. Both are cheap to test on arrival.
Mesh size gives the cut-off, not the distribution. A powder can pass 99.5% through 200 mesh and still hold a coarse tail that sediments in a drink or speckles a pale sponge. For beverage or coating use, request the full distribution and run a dispersion test.
Low-density powder fills bags quickly and dusts heavily; high-density powder flows better but can dose unevenly by volume. If your line doses by volume, put bulk density in your purchase specification.
Cocoa powder is a food, not a hazardous chemical, so most suppliers issue a sheet classifying it as non-hazardous. It is still required: forwarders, warehouses and customers' EHS teams ask for it, in the 16-section GHS layout.
Section 2, hazards: not classified under CLP or GHS, and no hazard pictogram.
Section 3, composition: cocoa solids and the alkalising agent, with CAS numbers where relevant.
Section 8, exposure: nuisance dust; local exhaust ventilation first, a dust mask as backup.
Section 9, properties: appearance, colour, odour, pH and bulk density, which should agree with your TDS.
Section 10, stability: hygroscopic; keep sealed, away from moisture, heat and strong odours.
Section 5, firefighting: organic powder can form an explosive dust cloud, so housekeeping and earthing matter as much as the extinguisher.
Section 14, transport: not dangerous goods, no UN number, not a marine pollutant.
A supplier who sends a hazardous-goods SDS for plain cocoa powder has probably used the wrong template. Some forwarders accept a short non-DG declaration instead of the full sheet, so ask which one yours wants before you chase paperwork.
Document | Scope | What to check |
|---|---|---|
Technical data sheet | The grade in general | Grade name, plant, guaranteed ranges, test methods |
Certificate of analysis | One production lot | Batch code, production date, actual results against the TDS ranges |
Safety data sheet | The substance, for safety and transport | Hazard classification, dust advice, transport status; never a quality spec |
The usual failure is a COA whose numbers cannot be traced to the TDS you approved, or one that repeats identical values lot after lot.
Fat given as a single figure with no tolerance and no test method.
Microbiology limited to "conforms to standard", with no limits or sample sizes.
No pH value, or the same pH quoted for every alkalised grade.
Heavy metals reported as "pass" rather than in mg/kg against a named limit.
No plant name, grade code or revision date to control versions.
No allergen or GMO statement, which most European and North American buyers request with the first sample.
The fastest route to a comparable sheet is to state your requirements first: application and process temperature, target fat range, pH or alkalisation level, mesh size, the limits of your destination market, packaging and pallet configuration, annual volume and first order size. A supplier who answers all of that in one document is usually one whose COA also matches.
A 20-foot container holds roughly 16–18 tonnes of palletised 25 kg bags, so settle payload and pallet height before price.
No. Plain cocoa powder is not a UN-listed dangerous good and carries no hazard class, so it moves as general cargo. Combustible dust in the warehouse is a handling issue, not a transport classification.
Yes, they answer different questions: the TDS defines the quality you buy, the SDS explains safe handling. Quality teams work from the TDS and COA, warehouses and forwarders from the SDS.
A TDS is revised whenever grade, process or specification changes, and reviewed annually. A COA is issued per lot and cannot be reused. If a supplier cannot say which TDS revision your quotation used, ask for the current one in writing.
Tell us your application, target fat content and pH range, and we will send the technical and safety data sheets for the matching grade, with a sample COA so you can compare the numbers before committing.
