In short: the ginger range splits cleanly into two halves with different documentation logic. Three grades are ratio extracts (4:1, 10:1, 20:1) with no quantified marker, and two are HPLC standardised (1% and 5%). If your specification requires a declared content of a named compound, a ratio grade cannot satisfy it — and one standardised grade here does not name its analyte on the certificate.

Grade comparison: ginger root extract powder
| Your requirement | Grade to specify | Why |
|---|---|---|
| Your specification needs a declared content | 5% HPLC assay grade | A quantified HPLC result is stated, and the assay percentage is declared |
| You need a low-concentration standardised grade | 1% Standardized Assay | Confirm the analyte in writing — it is not identified on the representative certificate |
| You need a botanical base without a marker | 4:1, 10:1 or 20:1 | Ratio grades are sold on identity and extraction ratio only |
| You are comparing ratio grades | Higher ratio is not automatically stronger | A 20:1 ratio is not a 20-fold marker level — it is a mass-ratio statement about the starting material |
Buyer Decision Guide
Work through these in order — each step narrows the next:
- Start from the claim, not the percentage. Identify the marker your label or customer specification names. A grade declaring a different marker is a different product, whatever its headline number.
- Fix the assay method in writing. UV and HPLC results are not interchangeable for the same material. State the method your specification requires.
- Ask for the batch, not the sheet. A specification describes a grade; the COA describes the batch you will receive. Require the batch number on the packing list.
- Check the physical parameters too. Loss on drying and the ash determination reveal process consistency. A result far outside the representative range is worth questioning even if the marker is on target.
- Confirm mesh size against your process. Particle size affects blending, tabletting and hydration. It can usually be adjusted if stated up front.
Qualification and COA Review
Every grade on this page is produced at the same certified manufacturing site, and each batch is released against its own certificate of analysis. When you review the COA, confirm four things: the batch number matches your order documents; the assay method is the one you specified; the marker result sits inside the declared limit; and the physical parameters are reported rather than left blank.
For first orders, requesting a retention sample alongside the shipping documents makes incoming inspection considerably easier.

Frequently Asked Questions
Does a 20:1 ginger extract contain twenty times the actives of a 1:1?
No. An extraction ratio describes how much starting botanical corresponds to the finished extract on a mass basis; it is not a statement about the concentration of any named compound. A 20:1 grade can have a different marker profile from a 10:1 grade but the ratio itself does not quantify it. If you need a quantified content, specify an HPLC-standardised grade.
Which ginger grades carry a quantified marker?
The 5% and the 1% Standardized Assay grades are the HPLC-assayed options. For the 1% grade, the representative certificate does not identify which compound the assay refers to, so ask for written confirmation of the analyte before approving the specification.
Why do the 4:1 and 10:1 grades show identical loss on drying and ash results?
Both grades list a loss on drying of 3.51% and an ash result of 3.11% on their representative certificates, and they share the same specification limits. Identical representative values across two grades usually indicate material drawn from a comparable process, but your own batch COA is what governs your order.
Is the ratio determined by a specific method?
For this range the ratio grades are documented as conforming to the declared ratio rather than being quantified by a marker assay. That is why a ratio grade cannot support a quantitative label claim about a specific compound.
Can I switch from a ratio grade to a standardised grade without reformulating?
Not automatically. A standardised grade declares a quantified content, so the amount needed to reach a given level differs from a ratio extract. Treat the change as a specification change and confirm the practical use level with your own formulation work.
What particle size are the ginger grades?
All five grades are milled at 98% through 80 mesh. If your process needs a different particle size distribution, state your requirement when you inquire.
What information should I include in an inquiry for ginger extract?
State whether you need a ratio grade or a quantified standardised grade, and if standardised, name the compound and the percentage you require. Also state the assay method you need declared and your destination market.
How do I verify a ginger batch before shipment?
Ask for the COA of your allocated batch, confirm the batch number against the packing list, and check which parameters the certificate reports. For ratio grades, confirm that the declared ratio appears on the COA rather than only on the product page.
