Private Label Green Tea From Vietnam: Tea Bags, Powder and Extract

Private label green tea is a practical way for a brand to launch or extend a tea range without owning gardens or a packing line. Vietnam is a sensible origin to look at: it is roughly the fifth largest tea exporter in the world, green tea accounts for roughly 30 percent of its tea export value and the country supplies tea bag, blending and RTD grades in volume. Some Vietnamese processors also run packing lines for tea bags and retail packs, and a smaller number handle powder or extract.

The difficulty is that capabilities vary a lot between suppliers. One factory may run modern pyramid bag machines but have no powder mill; another may mill fine powder but pack only in bulk bags. This guide sets out the main private-label formats, what drives MOQs, which packing materials to specify and what to put in your RFQ so suppliers can quote accurately.

The main private-label formats

Each format uses a different leaf input and different equipment, so treat them as separate products even when they come from the same garden.

For grade definitions and typical uses of each leaf type, see the green tea grades page.

Loose leaf retail

Loose leaf is the lowest-risk private-label format because the product is the tea itself. The main decisions are grade, origin claim and pack format: kraft or foil stand-up pouches with a zip, paper cans, metal tins or gift boxes. Specify the net weight per pack, whether the pack is nitrogen flushed and whether a one-way valve or oxygen absorber is needed. Premium single-origin claims such as Thai Nguyen or Tan Cuong should be backed by the supplier’s own gardens or documented cooperative sourcing, because the claim will appear on your label.

Tea bags

Flat bags

Flat bags are the highest-volume format in Vietnamese packing. The key variables are:

• Fill weight per bag, and the allowed tolerance.
• Filter paper: heat-seal or non heat-seal, and whether it must be free of certain binders. Ask the supplier for the paper grade and its food-contact declaration.
• String and tag: stapled or knotted, tag material and print.
• Envelope: none, paper or foil laminate. Foil envelopes protect aroma and moisture better and cost more.
• Outer box: number of bags, board type, printing and shrink wrap.

Leaf for tea bags is usually BOP or fannings. Specify the particle size range and a maximum dust content, since fine dust escapes the filter and clouds the cup.

Pyramid bags

Pyramid bags hold larger leaf and look better in the cup, so they suit premium and blended ranges. Ask what the mesh is made of (nylon, PET or PLA based material) and whether the supplier can document it for your market. If you plan to call the bag “plant-based” or “compostable”, ask for the certificate behind the claim; not every PLA mesh meets the same standard. Fewer Vietnamese suppliers run pyramid machines than flat bag machines, so this format narrows your shortlist.

Green tea powder and matcha-style powder

This is the format where buyers most need to ask detailed questions.

Matcha in the Japanese sense is made from tencha: tea plants shaded for several weeks before harvest, leaf steamed and dried without rolling, stems and veins removed, then ground very finely, traditionally on stone mills. Shading raises chlorophyll and amino acid content and gives the bright color and sweet taste associated with high grades.

Capacity for this kind of shade-grown tencha in Vietnam is limited. Much of the powder offered as “matcha” from Vietnam is green tea powder milled from conventional steamed or pan-fired leaf. That product has real uses: lattes, bubble tea, bakery, ice cream and blends. It is not the same as Japanese ceremonial matcha, and labeling it as such creates a risk for your brand.

Before you place an order, ask the supplier:

1. Were the plants shaded before harvest? For how long and with what method?
2. Was the leaf steamed or pan-fired, and was it rolled?
3. Were stems and veins removed before milling?
4. What mill was used (stone, ball or air-jet), and what particle size is achieved?
5. What are the moisture limit, color specification and microbiological limits?
6. Can you have a sample from the actual production batch, not a reference sample?

Powder needs tighter packing than leaf. Specify foil or metallized pouches or tins, nitrogen flushing, oxygen absorbers where suitable and cold or cool storage before shipment if the supplier offers it. Color fades quickly with heat, light and oxygen, so ask about the time between milling and packing.

Extract

Green tea extract covers several products: instant tea powder, liquid concentrate for beverage makers and extracts standardized to a polyphenol or catechin content for supplements. Vietnamese capacity exists but is concentrated in a small number of processors, and buyers should expect to share more technical detail before getting a quote.

For extract, specify the extraction solvent (water only, or water and ethanol), any carrier such as maltodextrin, the target solids or active content and the test method (usually HPLC for catechins), solubility and the residue and heavy metal panel. For supplement use, check the rules in your market carefully; green tea extract in supplements is regulated more strictly than tea as a beverage in several jurisdictions.

What sets private-label MOQs

For bulk tea the usual MOQ is 1 metric ton, packed in 25 to 50 kg foil-lined paper sacks. Retail MOQs are different. In most cases the tea is not the constraint; printed packaging is. Printed films, envelopes and cartons have their own minimum runs set by the printer, and a supplier will pass those minimums on to you.

Ways to lower the entry point:

• Stock packaging with a printed label instead of fully printed films or boxes.
• One design across several SKUs with a variable sticker for the flavor or weight.
• Plain envelopes inside a printed outer box.
• A first run in bulk, packed in your own market, while you test demand.

Ask every supplier for two numbers: its tea MOQ and its packaging MOQ for your chosen format. They are often very different.

Packing materials and food contact

Retail packs are food-contact materials, and the rules sit in your destination market. Ask the supplier for food-contact declarations or migration test reports for filter paper, mesh, laminated films, tins and inks. For EU sale, compare them with EU food contact requirements; for the US, with FDA food contact rules. Organic products also need the packing site to be covered by the organic certificate if packing happens after certification.

Labeling responsibilities

The supplier prints to the artwork you approve. You, as brand owner, are responsible for label content: product name, ingredients, net quantity, lot code, best-before date, country of origin and the name and address of the responsible operator in your market. The EU rules are set out in Regulation (EU) No 1169/2011; in the US, FDA food labeling rules apply. Organic logos (USDA, EU or JAS) can only be used if the certified chain covers every step, including packing.

Supply print-ready artwork, approve a printed proof and ask for photos of the first production packs before the balance payment.

Timeline

A typical first private-label run follows this order: sample approval, packaging specification, artwork and proof approval, packaging material procurement, production and packing, then inspection and shipment. Tea production usually takes 3 to 5 weeks after the proforma invoice, and printed packaging procurement can add time on top of that, so plan the artwork stage early. Ocean transit from Ho Chi Minh City to US West Coast and EU main ports is roughly 25 to 35 days.

What to put in your RFQ

A private-label RFQ that suppliers can quote from includes:

• Format and pack size (for example, 20 flat bags of 2 g in foil envelopes, printed box).
• Leaf grade, style and origin, or the approved sample reference.
• Residue panel for your destination market; our pesticide residue guide covers how to set it.
• Packing materials, including food-contact documentation required.
• Artwork status and number of SKUs.
• Quantity per SKU for the first run and expected annual volume.
• Certifications required (organic, HACCP, ISO 22000, FSSC 22000 or other).
• Incoterm, port and target delivery date.

Our guide to writing a green tea specification covers the tea side of the spec in more detail. Third-party inspection (SGS, Bureau Veritas or Intertek, typically 350 to 600 USD per container) is arranged and paid by the buyer, and for retail packs you should ask the inspector to check print, fill weight and seal quality as well as the tea.

Send a green tea spec

When you know the format and roughly how many units you need, send your private-label spec through the RFQ form. We review each request and introduce up to 3 Vietnamese suppliers whose equipment fits the format, within 24 business hours and free for buyers. You work directly with the supplier on samples, artwork, price and contract. If your formulation or artwork is confidential, note it on the RFQ form and an NDA can be signed before details are shared. Settle the leaf style and cut first: see our guide to bulk green tea.
