In tea exports, most lost opportunities don’t arise at the price negotiation table, but rather in the documentation process. Businesses may have good raw materials and competitive prices, but when partners send questionnaires about certifications and test results, they are unable to answer, and the negotiations stop there. This is also the underlying reason why the average export price of Vietnamese tea in 2025 will only be around US$1,700 per ton, approximately 60-65% of the world average. This article systematizes the standards required by the international market, explains why residue limits are the biggest barrier, and proposes a practical roadmap for small and medium-sized enterprises.
1. Four sets of standards need to be distinguished.
The standards system in the tea industry is often grouped into a vague whole, leaving businesses unsure where to begin. In reality, there are four distinct groups. Group one consists of food safety standards, demonstrating that the factory operates under controlled conditions. Group two includes certifications required by specific markets, such as HALAL for Muslim countries or Kosher for certain distribution channels.
Group three consists of certifications related to farming methods and sustainability, including organic certification, Rainforest Alliance, and fair trade. Group four is not a certification but a mandatory technical threshold: pesticide residue, heavy metals, microorganisms, and moisture content. The first three groups are proactive initiatives by businesses; the last group is a requirement, without exception.
2. Food safety standards: HACCP, ISO 22000, BRC, and IFS
HACCP is the most familiar starting point: a system for analyzing hazards and identifying critical control points in the production process. ISO 22000 expands further, integrating HACCP into a complete food safety management system with full procedures, documentation, and improvement mechanisms. These two certifications are the minimum requirements to be considered a serious supplier in most markets.
BRC and IFS are two higher standards, required by major retail chains in the UK and continental Europe. Businesses wanting to get their goods on European supermarket shelves often cannot avoid them. A common feature of both groups is that they assess the operational system, not just the shipment itself: factories, pest control, internal traceability, staff training, and incident response capabilities are all included in the inspection scope.
3. HALAL – the key to the Muslim market
HALAL certification confirms that a product and its production process comply with Islamic regulations. In the tea industry, the tea leaves themselves are not the primary source of the raw material; therefore, the focus of the assessment lies in additives, flavorings, processing aids, factory conditions, and the risk of cross-contamination with non-HALAL products.
This certification offers the highest cost-effectiveness ratio for Vietnamese tea businesses. The reason is that the Muslim market segment coincides with areas where Vietnamese tea already has a foothold or is growing: Iraq and the Middle East, North Africa, Malaysia, Indonesia, and large Muslim communities in many other countries. It’s important to note that HALAL certification organizations are recognized differently in each country, so it’s crucial to choose a certification body that is recognized by the target market to avoid having the certification unusable.
4. Organic and Kosher Certification
Organic certification, according to the US USDA Organic or European EU Organic standards, is the ticket to the highest-priced segment, but also the most difficult to obtain. The requirements include not only stopping the use of synthetic chemicals but also undergoing a long transition period spanning several years, establishing buffer zones, maintaining comprehensive farming records, and undergoing regular on-site inspections.
With an average household farming area of about 0.2 hectares, organic certification in Vietnam is almost mandatory and must be done in groups through cooperatives. The target of developing 11,000 hectares of organic tea by 2030 shows that this direction has been established at the industry level. Kosher certification, based on Jewish culinary regulations, has a simpler process than organic, is more affordable, and is useful for accessing certain distribution channels in the US and Israel.
5. Sustainability Certification: Rainforest Alliance and Fair Trade
The Rainforest Alliance focuses on sustainable farming, biodiversity conservation, water resource management, and workers’ working conditions. Fair trade emphasizes minimum purchase prices and a premium reinvested in farming communities. Both are geared towards consumers in developed markets, where questions about the ethical origin of products are increasingly prevalent.
For Vietnamese businesses, this group of certifications is often not a top priority, but it should be included in a medium-term plan if targeting Europe or North America. The advantage is that many of their requirements coincide with the process of building interconnected raw material sourcing areas, which businesses must undertake to address the issue of consistent quality. In other words, one investment can serve two goals simultaneously.
6. MRL (Maximum Residue Limit) – the biggest obstacle for Vietnamese tea.
MRL (Maximum Residue Limit) is the maximum permissible residue level of a pesticide on a product. This is the group of requirements that Vietnamese tea faces the most, and is also the direct reason why the selling price does not match the quality of the raw materials. The unique characteristics of tea make the problem much more serious than many other products: consumers drink tea brewed from dried leaves, and the leaves are not washed before processing, so any residue on the leaves goes directly into the final product.
The level of strictness varies significantly between markets. The European Union and Japan apply very low thresholds for hundreds of active ingredients, with lists that are regularly reviewed and updated, and some ingredients having thresholds lowered to almost zero. This means that a farming practice that meets standards this year could still be in violation next year if the business does not update its regulations.
7. Why are residues difficult to treat, and where should they be treated?
The root cause lies not in the factory but in the tea plantations. The average household size of about 0.2 hectares results in fragmented raw material areas, with each household having its own spraying practices, inconsistent pre-harvest waiting periods, and just a few households making mistakes can cause the entire batch to exceed the permitted limits. Businesses that purchase these unregulated plantations are almost unable to control this factor.
The only sustainable approach is control at the source: signing contracts with cooperatives or groups of households, providing a list of permitted pesticides, training on quarantine periods, keeping cultivation logs, and paying higher prices for standardized raw materials. Switching to new varieties – which currently account for about 54% of the country’s cultivated area – also helps because new varieties generally have better resistance, reducing the need for pesticides.
8. Testing and sampling: get it right from the start.
Test results are only valid if they come from an accredited laboratory and are recognized by the target market. A test result from an unaccredited unit may be meaningless to European or Japanese buyers, even if the results appear satisfactory.
Sampling methods also determine reliability. Samples must be representative of the entire batch: samples should be taken from multiple locations within the batch, thoroughly mixed, and then drawn for analysis, accompanied by a clear sampling record. Businesses should conduct two-tiered testing: screening at the raw material input stage to eliminate potentially risky batches early, and full testing according to market requirements at the finished product stage. Simultaneously, control samples from each export batch should be retained for a sufficiently long period to provide evidence in case of complaints.
9. Costs, time, and resource allocation.
Let’s face the reality: certification costs money and time. Basic food safety certifications typically take several months to build the system and complete the assessment. HALAL and Kosher certifications have relatively simpler processes. Organic certification is the heaviest investment because it involves a lengthy transition period before certification, during which time the product cannot yet be sold at organic prices.
In addition to the initial assessment fee, businesses must also factor in annual maintenance costs, periodic testing costs, and personnel costs for managing the system. A sound allocation principle is to only pursue certification when a specific target market has been identified and there are genuine potential customers. Obtaining certification simply because it’s trendy and not tied to orders is the quickest way for a small or medium-sized enterprise to waste resources.
10. A step-by-step roadmap for small and medium-sized enterprises.
The logical roadmap consists of four stages in the correct order. Stage one is groundwork cleaning: controlling the raw material source, treating residues, and building a traceability record from farm to shipment. Without completing this step, any subsequent certifications are meaningless. Stage two is standardizing the factory with HACCP or ISO 22000, sufficient to work with most Asian and Middle Eastern markets.
Phase three involves obtaining additional certifications for the chosen market: HALAL for the Middle East and North Africa, and organic and sustainable certifications for Europe, Japan, and the US. Phase four involves finalizing labeling and packaging according to the regulations of the importing country, including country of origin, ingredients, net weight, expiration date, packing facility code, and local language. A price of approximately $2,000 per ton when exporting to Europe, compared to an average of $1,700, is a measurable reward for businesses that complete this process.
