Herbal teas are often considered a secondary product category in a tea distributor’s catalog, sold as an add-on rather than a core focus. From a supply-side perspective, this assessment overlooks a crucial fact: this is a product group where Vietnamese businesses can differentiate themselves most quickly, with the lowest investment, and without needing to own tea plantations. While exported tea remains stagnant at an average price of around $1,700 per ton due to being sold in its raw form, the herbal tea segment has a completely different value chain structure. This article analyzes this segment from the perspective of supply capacity, processing, quality documentation, and export potential.
1. Product boundaries need to be clarified before discussing supply.
First, it’s necessary to distinguish between three groups that are often grouped together. Pure tea is a product from the Camellia sinensis plant. Flavored tea still uses a pure tea base, but adds flowers such as lotus, jasmine, wolfberry, osmanthus, and chrysanthemum. Herbal tea contains no tea leaves and is made from the flowers, leaves, stems, roots, and fruits of other species: chrysanthemum, artichoke, pagoda flower, lotus leaves, ginger, lemongrass, and Centella asiatica.
This distinction isn’t just a matter of terminology; it determines the entire supply chain. Authentic tea depends on the tea-growing region, the harvest season, and the tea processing technology. Herbal tea depends on the medicinal plant region, the drying and preservation techniques used, and is subject to different regulations regarding quality declarations. Businesses entering this category with the mindset of a traditional tea maker often encounter difficulties right from the raw material and documentation stages.
2. Domestic medicinal plant raw material sources are a readily available advantage.
Vietnam’s greatest strength in this segment is its abundant and widely distributed local raw materials. Chrysanthemums, artichokes, pagoda flowers, milk thistle, Centella asiatica, ginger, lemongrass, lotus leaves, perilla, cinnamon, and star anise are all grown or harvested domestically, stretching from the northern mountainous regions and the Central Highlands to the plains. Many of these are associated with long-standing traditional uses, so no significant effort is needed to educate the market.
Compared to tea plants, herbs have three advantages in terms of supply: a shorter harvesting cycle allowing for faster production adjustments, lower initial investment costs for cultivation areas, and the ability to rotate or intercrop. The disadvantage is that quality fluctuates significantly depending on the season and on-site processing methods, making standardizing input materials a central rather than a secondary issue.
3. The initial processing and drying stages largely determine the quality.
With tea, the value is primarily created in the post-harvest processing stage. With herbs, much of the quality is determined earlier, right from the harvesting stage with the right timing and proper drying. Overripe chrysanthemums will have damaged petals and lose their fragrance; lotus leaves dried at high temperatures will turn brown and lose their aroma; ginger and lemongrass sliced too thickly will not dry evenly, leading to mold during storage.
This is why the price difference between the same type of herb on the market can be many times greater, making it very difficult to distinguish with the naked eye. Businesses that want to operate seriously usually have to control at least three parameters: the moisture content of the finished product, the percentage of impurities, and the storage conditions after drying. Wholesalers should directly ask about these three figures, instead of just looking at the color and the quoted price.
4. Domestic processing capacity has improved significantly.
In recent years, the processing capabilities of domestic facilities have gone beyond simply drying and packaging. Many have invested in freeze-drying or sublimation dryers to preserve color and flavor, screening machines to classify impurities, grinding and weighing equipment for filter bag packaging, and vacuum or inert gas-blown packaging lines. Some facilities have added extraction, making extracts and soluble powders.
This improvement opens up a very real opportunity: businesses that don’t own their own growing areas can still build their own line of herbal products through outsourcing. But because of the low barriers to entry, the market is flooded with similar products, differing only in packaging. Sustainable differentiation, therefore, lies not in having a product, but in controlling the raw materials and maintaining a consistent formula across multiple batches.
5. Barriers to disclosing quality and how to talk about efficacy.
This is the biggest difference compared to regular tea, and also where many businesses stumble. Herbal products easily fall into the boundary between food and health products, leading to stricter documentation requirements: self-declaration or registration depending on the group, periodic testing certificates, control of microbiological indicators, heavy metals, and pesticide residues.
This comes with limitations on how the product is communicated. Content on packaging and in sales consultations must not describe the product as medicine or claim it has curative properties. For distributors, the safest approach is to describe the ingredients, usage instructions, and context of use, rather than promising efficacy. This is not a formality: complete documentation is a requirement for getting the product into supermarkets, pharmacy chains, hotels, and export channels.
6. The cost structure is completely different from traditional tea.
From a financial perspective, herbs have a very unique cost structure. The raw material costs of many are significantly lower than those of high-quality tea leaves, but the loss rate after drying is high, with some losing a large portion of their weight from fresh to dried. In return, dried products are often lighter and bulkier, resulting in higher packaging and transportation costs per unit weight compared to tea.
Consequently, the profit margin of the herbal product group depends more on packaging than on the price of raw materials. The same type of chamomile flower, sold bulk by the kilogram and in small tea bags/boxes, can yield vastly different returns per kilogram. This is why this product group is particularly well-suited to a strategy of deep processing and on-site packaging.
7. Export potential of the herbal group.
Vietnamese tea is present in more than 70 countries and territories, but mainly in raw form, with an average price of about US$1,700 per ton, equivalent to 60–65% of the world average. The herbal tea group follows a different logic: the product is not directly compared to tea from major producing countries, and its value is assessed based on the unique characteristics of the local ingredients.
Technical barriers remain, and they are significant. The European market has very strict residue control and a list of permitted plant-based ingredients; the US applies FDA regulations; and the Middle East requires HALAL certification. Businesses aiming for long-term success need to prepare HACCP or ISO 22000 certifications from the outset, along with traceability records for raw materials. In return, overcoming these hurdles often allows products to be sold at a much better price point than raw tea.
8. Why is this group the easiest to differentiate for Vietnamese brands?
Competition in the tea sector is essentially competition with established tea brands that have long been ingrained in the minds of international buyers. In the herbal sector, the situation is quite different: local ingredients, usage practices, and blending formulas become irreplicable elements. A product based on lotus leaves, Da Lat artichoke, milk thistle, or cinnamon from the northern mountains carries a story that foreign producers would find difficult to replicate.
Another advantage is the ability to combine ingredients. Blended teas, combining real tea base with local herbs, allow businesses to both utilize domestic tea resources and create unique flavors, while also increasing selling prices. This is a suitable approach for small and medium-sized enterprises, which may struggle to compete on volume but can certainly compete through consistent formulas and quality.
9. Risks to anticipate on the supply side
The biggest risk is the unstable supply of raw materials. Many herbs have short growing seasons and are grown on small, scattered plots of land, so when demand spikes, the price of raw materials can increase many times over in a single season, leading to the mixing of inferior quality products. The second risk is storage: herbs absorb moisture strongly, are prone to mold, and lose their flavor faster than tea, so their actual commercial shelf life is often shorter than the expiration date on the packaging if storage conditions are not adequate.
The third risk is legal and media-related, where salespeople inadvertently describe the product as medicine. Prevention involves three things: signing seasonal raw material contracts with clear technical specifications, controlling inventory conditions and turnover, and standardizing sales advice into a common document instead of having everyone giving different opinions.
10. Implications for dealers, distributors, and businesses
Overall, herbal tea is a segment with low barriers to entry but high barriers to survival. Anyone can launch a few product lines; only a few maintain consistent quality across multiple raw material cycles. For distributors, the sensible approach is to choose a few product lines with stable year-round demand, partner with suppliers who control the raw material sourcing area and have complete documentation, rather than expanding the product range based on trends.
For businesses targeting international markets, this is a worthwhile investment because it allows for the sale of finished, branded products right from the start, instead of repeating the old pattern of exporting large quantities of raw materials in bags. In the context of the tea industry seeking to bridge the gap between $1,700 per ton and the global average of $2,600 per ton, herbal products represent one of the quickest paths.
