When we built TeaGoodTea, we made one non-negotiable decision early on: every tea we sell must be able to pass the most rigorous pesticide testing in the world. Not just claim to be clean — prove it.
That commitment led us to a small number of farms in China that could actually meet that bar. This post is our way of showing you exactly what "clean tea" means in practice, and why the certifications behind our teas matter.
"We don't choose suppliers because they have a certificate. We choose suppliers because their tea passes 280+ tests with zero detections — 10 years in a row."
01 — The Standard We Hold Our Suppliers To
Most tea sold in the US is tested to FDA standards. Those standards are reasonable — but they are not the most demanding in the world. We benchmark our suppliers against the EU standard, which is widely considered the most stringent pesticide framework for tea imports globally.
EU Import Standard (MRL) For pesticides without an established maximum residue limit, the EU requires 0.01 mg/kg — effectively "not detectable." This applies even to agrochemicals that other countries permit at higher levels.
SGS Testing Protocol — 280+ items screened SGS Group is one of the world's largest third-party testing and certification organizations, operating in 143 countries. Their tea residue panel covers over 280 individual pesticide compounds per test cycle.
02 — Our Featured Supplier: Handtao
Origin: Gao Yuan Village, Chao'an District, Chaozhou — Guangdong, China
Nestled in the high-altitude growing zones of the Phoenix Mountain range, Handtao's tea garden has been farmed under zero-pesticide, zero-fertilizer, and zero-herbicide protocols since the farm's founding. The elevation and natural biodiversity of this region produce the complex floral and honey notes Phoenix Dan Cong oolongs are known for.
- 10 consecutive years passing SGS EU pesticide testing
- 280+ pesticide compounds tested each cycle
- 0 detections across all test results (ND — Not Detected)
Ten consecutive years of zero-detection results is not an accident — it reflects a farming system deliberately designed to never need chemical intervention. Handtao uses ecological planting methods that work with the natural ecosystem of the mountain environment rather than against it.
03 — Dual Organic Certification
SGS testing tells us what's not in the tea. Organic certification tells us how the tea was grown. Handtao holds both Chinese and EU organic certification — two independent regulatory bodies, two separate auditing frameworks, one consistent result.
China Organic Product Certification Issued by COFCC under China's GB/T 19630 standard. Covers production, processing, and management practices across the full growing cycle. Certificate No.: F45OP1900030
EU Organic Certification Issued under EU Regulation 2018/848. Prohibits all synthetic pesticides, fertilizers, and growth hormones at every stage of production. Certificate No.: CN-BIO-154.156-0000131.2024.001
The EU organic framework in particular is structured around what it calls a "closed loop" on synthetic substances — meaning it's not enough to avoid pesticides at harvest time. Every input across the entire growing and processing chain must be free of synthetic compounds. This is the standard Handtao has met, continuously, for years.
04 — What This Means for You
When you buy a Phoenix Dan Cong oolong from TeaGoodTea, you're not buying a tea that "claims" to be clean. You're buying a tea that has been independently tested to EU import standards — tested against 280 individual compounds — and passed every single one, year after year.
We believe transparency in sourcing is part of what makes a tea brand worth trusting. This is the first in a series of posts where we'll introduce the suppliers, farms, and certifications behind our collection.
TeaGoodTea Sourcing Standard
Every tea we carry must be traceable to its origin, backed by third-party testing, and grown without synthetic inputs. We publish the certifications so you don't have to take our word for it.
