Measures sulphur dioxide or sulphite residue.

Some processing uses sulphur, and many buyers set a maximum.

Often used for: Cinnamon, desiccated coconut, dried fruit.

How it works

1. Tell us the product, the lot or supplier if you know it, and the destination market.
2. We reply with the laboratory, the test method, the turnaround and the full cost. We say whether the test is ISO/IEC 17025 accredited at that lab.
3. A sample is drawn from the lot and delivered to the lab.
4. The laboratory issues its report in its own name, directly to you.

Priced per sample, not per kilo, so testing 100 grams costs the same as testing a container. Nothing is charged until you approve the quote. You can also name a laboratory yourself, including one in your own country.

How lab testing and COAs work

What to send us

• The product, for example cinnamon quills or desiccated coconut
• The lot number or supplier, if you know it
• The destination market, and any limit your buyer or regulator sets
• Whether you want a specific laboratory, including one in your own country

When to test

Test before shipment, once the lot is packed. Sulphur dioxide limits differ by product and by market, so tell us where the goods will be sold. If you already have a limit in your purchase contract, send it and we compare the report against that figure.

Reading the result

The report gives the sulphur dioxide found in the sample, usually in milligrams per kilogram, and names the method used. A product labeled sulphite free should show a result below the level your market sets for that claim. Keep the report with the shipping documents for that lot.
