Ang Thong: Thailand's Major Rice Milling Province — Production, Mills & Sourcing Guide

When sourcing Thai rice, the province of origin matters. Ang Thong — located in Thailand's central plains, approximately 100 km north of Bangkok — is one of the country's major rice milling provinces. Together with neighbouring Suphanburi and Phichit, Ang Thong forms a milling corridor that processes millions of metric tons of paddy rice each year and supplies a significant share of Thailand's 8–9 MMT annual rice export volume.

Ang Thong's central plains climate is best suited to non-aromatic white rice varieties — the highest-volume export category. The main varieties milled in Ang Thong include: Khao Suphanburi 1 (RD49): A high-yield, disease-resistant white rice variety developed for Thailand's central plains. Produces large, translucent grains with low broken percentage — ideal for 5% and 10% broken grade exports to Africa, Middle East, and Asia. Khao Chai Nat 1 (CNT1): Another central plains variety known for good milling recovery and consistent quality. Widely grown in Ang Thong and Suphanburi districts. Glutinous (sticky) rice: Some Ang Thong sub-districts produce glutinous rice varieties, though the primary glutinous rice region is the northeastern Isan provinces. Ang Thong mills do process sticky rice from purchased paddy. Parboiled rice processing: Many Ang Thong mills are equipped with parboiling infrastructure, steam-treating white rice before milling to produce the golden-amber parboiled rice most popular in West Africa (Nigeria, Ghana, Senegal).

Thailand's National Rice Policy Committee tracks paddy production by province. Ang Thong province typically harvests 200,000–350,000 metric tons of paddy rice per crop year across its main and second crops. At an average milling yield of 60–65%, this translates to approximately 120,000–230,000 MT of milled white rice available for export per year — plus rice purchased from neighbouring provinces for processing through local mills. When combined with Suphanburi (Thailand's largest paddy-producing province at 1.5–2.0 MMT/year) and Phichit (0.8–1.2 MMT/year), the Ang Thong–Suphanburi–Phichit milling corridor accounts for a significant share of Thailand's total annual export of 8–9 million metric tons.

Sourcing direct from Ang Thong and major rice milling provinces requires understanding the Thai rice supply chain: 1. Factory-direct mills: The largest mills in Ang Thong operate their own paddy purchasing, milling, polishing, and export operations. A factory-direct relationship eliminates trading company margins and provides the best FOB prices. Look for mills with active DFT (Department of Foreign Trade) export licenses. 2. Rice brokers and aggregators: Smaller Ang Thong mills often sell through Bangkok-based brokers who aggregate container loads from multiple mills. This is efficient for buyers who want specific grade combinations but sacrifices price transparency. 3. Export trading companies: Many Bangkok-based rice trading companies source from Ang Thong mills for their export business. They offer convenience and sometimes multi-origin blending but at higher margins. Best practice: For buyers wanting Ang Thong or central plains white rice, request a Certificate of Origin showing the rice was grown and milled in Thailand, and ask for the DFT rice export license number to verify the supplier's export credentials.

Rice sourced from Ang Thong and major central plains milling provinces is typically exported as non-aromatic white rice. Current 2026 FOB Bangkok/Laem Chabang prices:

Grade	FOB Price (2026)	Notes
---	---	---
White Rice 5% broken	$440–480/MT	Most common Ang Thong export grade
White Rice 25% broken	$415–445/MT	Price-sensitive markets (Nigeria, Senegal)
Parboiled Rice 5% broken	$560–610/MT	Nigeria, Ghana, Saudi Arabia
Glutinous Rice (standard)	$490–540/MT	China, Japan, SE Asia
White Rice 100% sorted	$460–500/MT	Premium Africa, Middle East

For Thai Hom Mali Jasmine rice, sourcing shifts to Isan (northeastern) provinces where the GI-certified variety is grown. Central plains mills like those in Ang Thong do process some jasmine rice from purchased paddy, but buyers wanting genuine Hom Mali certification should specify GI-certified stock from northeastern origin.

Importers considering direct mill relationships in Ang Thong should plan a factory visit. The province is accessible from Bangkok in approximately 90 minutes via Route 32 (Asia Highway). Key things to verify during a mill visit:

• Milling capacity: Ask to see the paddy intake, milling, polishing, color sorting, and bagging lines running
• Storage capacity: Verify paddy silos or dry storage warehouses — larger capacity = more supply security
• Lab equipment: In-house moisture meters, whiteness meters, and broken-grain sieves are minimum requirements for quality-conscious exporters
• Certifications displayed: ISO 22000, HACCP, GMP, and Halal certificates should be current and displayed prominently
• Export documentation samples: Ask to see a recent Proforma Invoice, packing list, phytosanitary certificate, and COA to assess documentation quality
