Organic Tea Certification: USDA Organic, India Organic and Biodynamic Tea

USDA Organic is the standard of the United States Department of Agriculture. It is built on the Organic Foods Production Act, and covers “various pivotal parameters associated with food production, including quality of soil and water, pest control, and rules for food additives,” as our Tea 101 put it.

The USDA does not inspect farms itself: it accredits certifying agencies, private, state or foreign, and those agencies inspect farms anywhere in the world. A USDA organic certification follows a tea through its whole journey, from the estate to the processing and packing. We gave the same explanation in 2021, under the question “What does organic mean?”

What that looked like for us

We went through this process ourselves. From September 2016, an accredited certifier, Control Union, inspected our facility in Siliguri and certified it for organic “handling and processing” under two standards at once: India’s national program and the USDA National Organic Program.

A handler certificate covers what happens after the garden. It checks that certified organic tea is kept apart from other tea, that nothing unapproved touches it during sorting and packing, and that every lot can be traced back to a certified estate. Ours ran until September 2025.

Other markets have their own organic standards, and India’s is recognized abroad. Our own certificate under it was “considered equivalent” to the European Union’s organic regulation and to Switzerland’s organic farming ordinance. In 2020 we also held a license to print the India Organic logo on our packs.

Some estates have been certified to private standards too. Temi, in Sikkim, moved fully to organic cultivation in 2005 under standards set by Switzerland’s Institute of Marketology (IMO), according to its product page.

Sikkim itself became the world’s first fully organic state, and won the UN’s Future Policy Gold Award in 2018 for it. Temi, overlooking the Himalayas, is the state’s largest and oldest tea garden.

When the gardens converted

Organic tea in India is newer than most of its gardens. The dates our estates give show how slow the change has been:

• Seeyok, Darjeeling: moved to organic farming in 1994, which makes it one of Darjeeling’s oldest certified organic estates.
• Selimbong, Darjeeling: farmed organically and biodynamically since 1995 under Tea Promoters India.
• Lakyrsiew, Meghalaya: planted on virgin land in 2003 and awarded its organic certification in 2010.
• Dharmsala Tea Company, Kangra: received its organic certification in 2017 for estates that include Mann.
• Banaspaty, Assam: the first certified organic tea garden in Assam, run by the third generation of the Mohan family.

Across the estates that supplied us in 2019, organic certificates came under at least six schemes: USDA Organic, Demeter, NASAA Organic for a Nepal garden, IMO and Japan’s JAS at Korakundah, and IndoCert. Whatever the scheme, the certificate has to be renewed after a fresh inspection.

This is the scope rule. Our certifier’s 2019 letter spelled it out: a scope certificate “cannot be used as an Import or Transaction Certificate for a certain product. Only your most recently issued Scope Certificate is valid.” In other words, the scope certificate says what a business may handle, and each shipment needs its own paperwork tying it to that certificate.

Certificates lapse at both ends. Jungpana’s wall said organic around 2014, and its teas list other certifications now. Our own organic handling certificates were last valid to September 2025.

That is why our product pages say “USDA Organic” only where the product data lists it, as a certification held by the estate, and why a tea such as Chota Tingrai, where an increasing share of the land is organically cultivated, is not called organic. For the full list, see Certified teas at Teabox.

Kausshal Dugarr, Teabox’s founder, called this the first myth about organic farming in a 2014 post on our blog: organic certification is extended to farms “that use chemicals that are approved” by the certifying government.

He wrote that post after long conversations with Rajiv Gupta, an agriculture graduate with 16 years in the field. Two more of its points matter for tea. Organic crops grow more slowly, with yields roughly 25% lower than conventional ones, and organic methods do improve soil that years of chemicals have worn down, though whether they are better in the long run is still argued.

Those lower yields add to the price of the seal. Peter Keen listed “the burdens of cost, administration, reduced crop yields, testing and inspection” that come with organic certification, and noted that they fall hardest on small farmers.

The same 2014 post argued that slower-growing organic bushes give a more flavorful tea, because the enzymes responsible for flavor have longer to develop. At Chota Tingrai, in Assam, we found in 2016 that Avantika Jalan had converted a third of her family’s garden to organic in the face of resistance from senior management, and her detractors had come round to the view that organic tea “does taste better.”

Not everyone agrees that the label is the whole story. Peter G. W. Keen, writing for our blog in 2016, warned that “‘pesticide’ does not automatically mean bad or ‘organic’ equate to good,” and that the organic label “is more an expensive certification than a pervasive solution.” He gave an example: the label “does not vouch for lead residues in the soil.”

Keen’s own test was wider than the seal. A tea that is certified organic, made by artisan methods and gives full information on its source, season and origin is, he wrote, “likely to taste better as well as be better.” Our view: organic is a meaningful promise about farming, but flavor still comes down to the estate, the season and the tea maker.

Some farms go further than the standard. Tea Promoters India, whose gardens include Seeyok in Darjeeling, told us in 2020: “We don’t use pesticides but depend on predator insects to combat pests,” treating soil fertility, plant growth and wildlife as “ecologically interconnected.” Seeyok itself is one of the few tea gardens in the world farmed biodynamically, treating the garden as a living entity and plucking some of its summer leaf by the light of the strawberry moon.

The method began in 1924, with eight lectures given to farmers in Breslau, now Wrocław in Poland, by the Austrian philosopher Rudolf Steiner. It treats the farm as a self-contained organism.

At Seeyok that means a night harvest. Every summer, under a full moon, about 50 women pluck a select patch of the estate’s best section by lantern light, for a batch of muscatel made for Teabox. “We believe on a full moon night the cosmic energies are at the highest and this enhances the quality of tea,” Ashwini Sashidhar, then Seeyok’s Chief Sustainability Officer, told us; that is the garden’s belief, not something we have measured. More on that harvest in Second flush tea.

Peter Keen saw biodynamics as “the broader and more accurate term for organic farming,” covering manuring, pruning cycles, planting density and composting in place of artificial fertilizers. Biodynamic gardens can be certified too: in our 2019 supplier records, Seeyok, Singell, Samabeong and Selimbong held Demeter certificates.
