Our process
One site. One standard. Every batch documented
Six steps from smallholder to shipping. Every litre traceable to the tree.
Six steps from smallholder to shipping. Every litre traceable to the tree.
Latex is biological. Viscosity drifts. Particle sizes vary. Mechanical stability shifts shift-to-shift. The only way to deliver a consistent product is to control every variable that touches it.
So we built one site, one process, one team. 120 GEA centrifuges running the same protocol every shift, three shifts a day. NIR validation on every batch. Documentation that follows each litre from the tree it tapped to the port it ships from. This is what a 180,000-tonne operation looks like when it's done by one operator, end-to-end.
Tatwin runs as 14 specialist departments across six production stages — not as one team wearing many hats. Hover any stage to see who handles your latex at that point. Each stage is detailed in its own section below.
Sourcing, contracts, and FSC™ FM compliance at the plantation.
Weighing, sampling, and initial DRC at receiving.
Centrifugation, ammonia preservation, skim recovery.
NIR validation, mechanical stability, trace metals, VFA/KOH.
FSC™ CoC, EUDR due diligence, batch certificates.
Packing, ISO tank loading, BoL and CoA dispatch.
Tat Win sources from 20,000+ smallholder farmers across 4,480+ certified hectares in Southern Thailand's rubber belt. Daily collection. GPS-tagged. EUDR-ready from day one of every shipment.
Our network of 20,000+ smallholder farmers has been built and maintained over 25 years of fair partnership. Generational relationships, formal contracts, transparent pricing tied to RSS3/STR20 benchmarks. The network is the company.
Dedicated collection centres receive field latex from morning tappings every day of the year. Lots are weighed, DRC-graded, and dispatched to the factory within hold-time windows that protect raw-material quality. Six logistic loops, one master schedule.
Every supplier is mapped — polygon coordinates, plot area, deforestation cut-off date, FSC™ certification status. Each lot of field latex carries the full EUDR due-diligence dataset from collection through dispatch, ready for European buyers under the EU Deforestation Regulation.
Quality assurance does not start at the factory gate — it starts at the collection centre. DRC is assessed, samples are pulled, and lots that fall short of intake spec are rejected before they travel further. This protects every downstream litre.
Co-signer of the UN IOM Migration framework. SEDEX SMETA 4-Pillar audited. Quizrr-trained workforce. The ethics of how the latex is harvested travels with every drum to your facility.
The industry's premium centrifugal architecture. The same separators used by the world's leading latex concentrate producers — running, in our case, at 120-unit scale.
Concentrated to a minimum 60% dry rubber content. Consistent particle-size distribution, guaranteed mechanical stability — batch after batch.
HA: 0.60% minimum. LA TZ: ≤0.29% with TMTD/ZnO stabilisation. Engineered to your downstream process — high-ammonia for shelf life, low-ammonia for sensitive applications.
Three shifts. Seven days. 180,000 MT annual capacity. The protocol is identical on every shift, every batch, every year. Consistency is a discipline.
Tat Win is the only Thai latex producer operating an in-house Near-Infrared (NIR) quality control laboratory. Every batch is validated end-to-end before release. This is not sampled audit — it is full-spec testing, batch by batch, signed off by our own scientists. Buyers receive a Certificate of Analysis with every shipment.
Spectroscopic verification of viscosity, DRC, TSC and chemical stability — non-destructive, batch by batch.
≥650 seconds minimum. Tested on every batch to guarantee colloidal stability through long-haul shipping.
Cu ≤8 mg/kg, Mn ≤8 mg/kg. Inductively-coupled plasma testing on a per-lot basis.
Volatile fatty acid and potassium hydroxide — the chemical fingerprint of latex freshness and shelf stability.
Tat Win holds FSC™ Chain of Custody certification (FSC™ C151320). Every production run, every purchase, every sale is logged within our chain-of-custody system. Buyers receive FSC™ CoC certificates with each shipment — valid for product labelling under FSC-STD-50-001. The documentation isn't a service we add. It's how the operation runs.
Every shipment leaves Tat Win with a complete dossier — bill of lading, certificate of analysis, FSC™ CoC certificate, EUDR due-diligence data. Buyers in Korea, China, Europe, the US — anywhere — can verify provenance end-to-end before the container ships.
20-ft and 40-ft ISO tanks for bulk export. Sea freight from Songkhla, Penang, and Laem Chabang to Korea, China, the EU, and the US. Direct-line relationships with major freight forwarders.
200 kg HDPE drums for smaller orders or specialised applications — medical grade, research grade, or buyer-specified container types.
Bill of Lading, Certificate of Analysis, FSC™ CoC certificate, EUDR due-diligence data — included with every order. No request needed. No paperwork follow-up. The documentation moves with the shipment.
Online access to source plantation data, batch history, certification status, audit logs. Your QA team can verify provenance for any order without an email round trip.
Contract-grade reliability. We ship to buyers across four continents. Long-term latex concentrate supply is a logistics discipline as much as a production discipline — and after 25 years, ours is built.
Our quality management runs under ISO 9001, environmental management under ISO 14001, and occupational health & safety under ISO 45001 — all audited annually by independent certification bodies.
Beyond ISO, we hold Halal certification, Green Industry accreditation from Thailand's Ministry of Industry, FSC™ CoC certification (C151320) subject to annual FSC surveillance audits, and SEDEX SMETA 4-Pillar coverage including labour, health and safety, environment, and business ethics.
We welcome buyer site visits and third-party audits at any time. Transparency isn't a policy — it's how we operate.
