Quick Answer — What should a green tea powder sample request include?
Confirm seven fields in writing before the supplier prepares a lot: (1) finished application and process route (RTD tea, tea latte, vending, food-service, dry mix or bakery); (2) target powder behavior — wetting, dispersion, sediment, clarity, color and taste; (3) COA and specification needs, including pesticide residue limits for the destination market; (4) sample quantity sized to your test matrix (100–500 g for bench work, 1–5 kg for a full application trial); (5) destination address and review timeline; (6) commercial expectations — MOQ, packing size, lead time and destination market; and (7) certificates covering the exact SKU (HACCP, ISO 22000, Halal, Kosher, organic). A precise request returns a representative sample and an accurate quotation in one round; a vague one starts a three-round clarification loop. Use the Instant Green Tea Powder product page as the commercial page, then send application, sample, COA and RFQ details via Contact HERBSEA.
1. Seven Fields Every Green Tea Powder Sample Request Must Cover
Green tea powder is not one commodity — it is a family of grades defined by leaf origin, particle size, solubility profile and drying technology. The same leaf can be sold as a coarse brewed-tea powder for vending, a fine instant powder for RTD lattes, or a culinary-grade product for bakery. Cover these seven fields so the supplier prepares the right lot the first time:
| Review point | Buyer input | Why it matters |
|---|---|---|
| Application | RTD tea, tea latte, vending drink, food-service drink, dry mix or bakery direction | Controls solubility and sensory priorities |
| Powder behavior | Wetting, dispersion, sediment, clarity, color and taste targets | These points decide sample approval |
| Document set | Specification sheet, representative COA, packing note and export files | Connects sample review with QA records |
| Sample plan | Sample quantity, formula matrix, destination address and review timeline | Clear test inputs help the supplier prepare the right grade |
| Commercial path | MOQ expectation, packing size, lead time and destination market | Supports fast quotation after sample approval |
| Compliance | Certificates covering the exact SKU (HACCP, ISO 22000, FSSC 22000, Halal, Kosher, organic) | Avoids a sample that cannot legally enter your market |
| Destination regulation | Pesticide MRL framework of the target market (EU, US, Japan, Korea, etc.) | Determines which residue fields the COA must show |
Use this guide as a pre-RFQ worksheet. If the specification is fixed, send the target powder behavior, COA fields, sample quantity, MOQ, packing and destination market. If the grade is still open, ask for available specification options with a representative COA and sample lot details.
2. Powder Type Matters: Instant Green Tea Powder vs Matcha vs Green Tea Extract
Buyers often request “green tea powder” and receive three very different materials. State the powder type explicitly so the sample matches your application:
| Dimension | Instant green tea powder | Matcha (stone-ground) | Green tea extract powder |
|---|---|---|---|
| Base material | Brewed green tea, concentrated and dried | Shade-grown leaf, milled whole | Concentrated extract standardized to a marker |
| Typical use | RTD tea, latte, vending, dry mix, bakery | Ceremonial and culinary-grade drinks, premium bakery | Supplement and functional beverage formulation |
| Solubility profile | Formulated for cold and hot dispersion | Suspends in liquid; fine particles can settle | Water-soluble, high assay per gram |
| Particle size | Coarse to fine depending on grade | Very fine (stone-ground) | Fine to very fine |
| COA focus | Solubility, color, assay, residues | Color (green hue), particle size, residues | Assay (EGCG/catechins), heavy metals, residues |
| Cost position | Mid | Premium | Mid to high per active unit |
The iHerbSea Instant Green Tea Powder page is the right commercial page for beverage, food-service and dry-mix applications; the Green Tea Extract Supplier page covers extract sourcing; the L-Theanine Green Tea Extract page covers HPLC-specified extract with COA path. Match the powder type to the application before requesting the sample.
3. Sample Review vs Bulk RFQ: Send the Right Request at the Right Time
Many buyers collapse the sample stage into the quotation stage and get neither. Samples verify physical behavior and document fit; RFQs verify commercial supply. Keep them separate:
| Dimension | Sample request | Bulk RFQ |
|---|---|---|
| Main purpose | Check solubility, color, sensory profile and document fit | Confirm commercial supply, packing, lead time and export details |
| Buyer input | Application, sample quantity, test matrix and COA needs | Quantity, MOQ expectation, packing size and destination market |
| Document focus | Lot-matched COA, specification sheet, certificate copies | Proforma invoice, packing list, export documents, certificate validity |
| Limit | Needs later commercial confirmation | Should follow sample approval when formula fit is strict |
Practical rule: request the sample first, evaluate it in your own matrix, then send the RFQ with the approved sample lot number attached. Industry experience puts sample-to-order conversion at roughly 20–30% — most inquiries never become orders, which is exactly why disciplined buyers use the sample stage to pre-qualify suppliers before any commercial commitment.
4. How Much Green Tea Powder Sample to Request
Sample quantity should follow your test plan, not a round number. Under-ordering forces a second sample round; over-ordering is freight waste. A common industry guideline: 100–500 g for solubility and sensory screening, and 1–5 kg per variant when the sample must support a full application trial or third-party residue testing (Geminate International, 2026). Many green tea powder suppliers quote 1–5 kg per variant for qualified buyers so the same lot covers both bench work and a small pilot run.
| Test purpose | Suggested quantity | What it verifies |
|---|---|---|
| Identity, color and aroma check | 50–100 g | Grade, drying technology, visual and olfactory screening |
| Solubility and sensory panel | 100–500 g | Wetting, dispersion, clarity, color and taste in your recipe |
| Full application trial | 1–5 kg per variant | Performance in the actual line, sweetener/acid/dairy interaction |
| Third-party COA testing | 500 g–2 kg | Pesticide residues, heavy metals, microbiology per destination rules |
Sample cost follows the tier: stock samples typically US$0–50 (often free, freight paid by buyer), custom specification-matched samples US$50–500, and pre-production samples US$100–1,000+ before bulk production. Delivery is commonly 3–7 working days by express courier. State the quantity and the test matrix in the request — a supplier that asks “what will you test with this?” is a better qualification signal than one that ships the smallest free pouch.
5. COA Fields That Matter for Green Tea Powder
A COA is only useful if it covers the fields your market and formula actually require. For green tea powder, focus on these:
- Lot-matched batch number — the COA must reference the exact sample lot, not a representative batch from another production run.
- Pesticide residues per destination — the EU framework (Regulation (EC) 396/2005) applies a default limit of 0.01 mg/kg to the roughly 500 substances screened for tea, and a small number of specific MRLs above that default (EU, 2025). Anthraquinone, a process contaminant formed in coal-fired drying, is a leading cause of EU green tea rejections at its 0.02 mg/kg limit (Blueeyes Bio, 2025). The US EPA, Japan and Korea operate their own lists (52, 210+ and 67 pesticide MRLs for tea respectively) with default 0.01 mg/kg rules for unlisted substances (ZATEST, 2026).
- Heavy metals — lead, arsenic, cadmium and mercury against EU Regulation 1881/2006 or equivalent destination limits.
- Microbiology — total plate count, coliforms, E. coli and salmonella per your spec.
- Physical fields — moisture, particle size, bulk density, solubility and color values, with the test methods stated.
- Traceability — production and best-before dates, origin, and any certification numbers tied to the lot.
Red flags in the sample stage: a supplier that refuses samples, charges an unusual courier fee for a 1 kg parcel, sends a generic COA with no batch number, or ships an unlabeled bag (Nutrisikakao, 2026). Any of these is a qualification signal to weigh before scaling up.
6. How to Evaluate the Sample: Solubility and Sensory Protocol
Testing the powder in your final matrix is the step most sample programs skip — and the one that avoids the most bulk-order surprises. Sweetener, acid, dairy and process route can all change visible performance:
- Dry-powder check — particle size, flow and color uniformity, no lumps, no foreign matter, no off-odors (musty, moldy or chemical).
- Solubility test — mix exactly as production will: hot water, cold water, dairy or plant base. Measure wetting time, clumping, sediment and clarity.
- Sensory test — taste in the finished formula, not in water alone. Note bitterness, astringency, color shift and flavor impact.
- Benchmark — compare against your current supplier or retained standard, and document results for a go/no-go record.
- Storage check — note how the powder behaves after open exposure: moisture uptake and caking tell you what packing the bulk lot will need.

Write the approval standard down: product name, grade, target particle size, acceptable color range, solubility requirement, packing type and document requirements. Keep the approved sample and its COA as the reference for the first commercial batch — “everyone liked the sample” is not a specification.
7. From Sample Approval to Bulk RFQ: MOQ, Packing and Lead Time
| Commercial field | What to confirm | Typical range / guidance |
|---|---|---|
| MOQ | Per SKU, per production run | Often 25 kg to 500 kg for stock grades; higher for custom or pre-production runs |
| Packing size | Inner and outer packing | 1–25 kg moisture-barrier foil bags inside cartons or drums; 25 kg is a common export unit |
| Lead time | Stock vs production lead | Stock 3–7 working days; production 2–4 weeks depending on volume and season |
| Destination market | Port, Incoterm, import requirements | Confirm HS line, label language, Halal/Kosher/organic documents per market |
| Payment terms | Deposit, balance, LC for larger programs | Align before the proforma invoice, not after |

Because green tea powder absorbs moisture and can clump, packing is not a footnote: multi-layer moisture-barrier packing with a desiccant policy protects both shelf life and flowability during sea freight. Complete details (quantity, MOQ expectation, packing size and destination market) let the supplier quote accurately in one round.
8. Market Data: Why Green Tea Powder Demand Is Growing
A short market context helps buyers set expectations on supply and pricing. Figures below are public industry estimates — use them for direction, not contract math.
| Data point | Value | Source / year |
|---|---|---|
| Global matcha green tea powder market | USD 1.47B (2024) → USD 1.59B (2025) → USD 2.86B (2032), CAGR 8.61% | Research and Markets / 360iResearch, 2025 |
| Global tea production | ~6.5 million tons | FAO, via Transparency Market Research, 2025 |
| China tea exports 2024 | 374,100 tons, USD 1.42B | China Customs, 2024 |
| China green tea exports 2024 | 323,900 tons, 86.6% of export volume; +4.7% YoY | China Customs, 2024 |
| EU tea residue framework | ~500 substances screened; default MRL 0.01 mg/kg for unlisted substances | Regulation (EC) 396/2005, 2025 |
| B2B sample-to-order conversion | ~20–30% of sample inquiries become orders | Industry observation, 2026 |
The category-wide growth in beverages, food-service and dry-mix formats means more SKUs, more origins and more price spread — which makes the sample stage more valuable, not less. Suppliers with export-grade certification stacks (FSSC 22000/HACCP among China export mills) and lot-matched documentation are the ones that can move from sample to bulk without re-qualification.
