Quality is not a department at Tian Yuan. It is the only way we know how to ship. All three factories are certified to ISO 9001:2015. Since 2015 we have been audited every year by independent third parties on C-TPAT security, social accountability, environmental management and quality — including a passed Bureau Veritas Vendor Code of Conduct & Security audit for a tier-1 US retailer. 160+ QA instruments across all plants. Our LEED-certified plant, SGS SMETA audit and ESG reporting are documented below.
All certificates are kept current and available for tier-1 buyer audit packs.
All three Tian Yuan plants — Taiwan, Tian You (Vietnam · Binh Duong) and Tian Yuan (Vietnam · Dong Nai) — hold current ISO 9001:2015 quality-management certificates from UKAS- or ANAB-accredited certification bodies. The Taiwan plant has held uninterrupted ISO certification for more than 25 years.



Our Tian You Vietnam plant has been audited by Bureau Veritas (one of the world's top-3 independent inspection bodies) on behalf of a tier-1 US retail buyer. The audit covered both the Vendor Code of Conduct (labour, ethics) and the Security Audit (supply-chain integrity). Audit passed.
A passed Bureau Veritas VCoC + Security audit substantially shortens the supplier-qualification process for other tier-1 US retailers — BV's findings are widely accepted across peer retail programmes.
4-pillar Sedex Members Ethical Trade Audit covering labour standards, health & safety, environment and business ethics. Conducted by SGS — the world's largest independent inspection and certification body. Passed. Walmart, Tesco, M&S, Carrefour, Aldi, IKEA and most major EU/UK retailers either require SMETA directly or accept it in lieu of their own audit.
Every part follows the same QA chain across all three plants. No part ships if it fails any step — and every step is logged for traceability.
Dimensional, durability and inline inspection across all three plants.
Plus: X-ray inspection on automated assembly lines, cross-hatch adhesion and coating-thickness testing, hardness testers, drop and burst test rigs, granite reference platforms, gap gauges, electronic calipers, digital force gauges, and custom checking fixtures designed per product.

LEED v4 BD+C is one of the strictest green-building standards. For tier-1 retail and EU buyers under CSRD, sourcing from a LEED-certified facility shortens the supplier ESG questionnaire and directly supports Scope 3 reporting. Our new plant was designed for this from day one — not retrofitted.
ISO 14001 (environmental management) is on our roadmap and will be added to this page once we are certified.
The new 30,000 m² (323,000 sq ft) Tian Yuan Vietnam plant was designed for export-buyer ESG requirements — not retrofitted to meet them.
Most tier-1 retail and EU buyers now require ESG evidence as part of supplier qualification. Here is the cadence we run.
