Where to Buy Industrial NaOH? Latest 2026 Price List for 32%-45%-50%-99% NaOH
TL;DR: Industrial NaOH (CAS 1310-73-2) comes in 4 main forms: 32%, 45%, 50% liquid caustic and 99% flakes. Each type suits different applications — from wastewater treatment to soap production. Loc Thien Chemicals supplies bulk NaOH with 6 nationwide warehouses, 20 specialized tankers, and COA/MSDS per production batch.
Types of Industrial NaOH — Which One Should You Buy?
Vietnam’s market currently offers 4 commercial NaOH types, differentiated by concentration and physical state. Choosing the right type directly impacts transportation costs, usage efficiency, and storage equipment requirements. Below is a detailed analysis of each type.
Liquid NaOH 32% — Applications & Reference Price
NaOH 32% is the most common liquid caustic concentration in Vietnam, produced via membrane cell technology. This clear, colorless liquid has a density of 1.348 g/ml at 20°C. It’s an economical choice for factories with short transport distances — since 68% of the weight is water, the logistics cost per kg of pure NaOH is higher compared to more concentrated solutions.
Main applications: acid neutralization in industrial wastewater treatment, pH adjustment in manufacturing, CIP (Clean-in-Place) sanitation in food plants. Reference prices fluctuate with raw material markets, typically being the lowest among NaOH types due to lower concentration and widespread production technology.
Liquid NaOH 45% — Applications & Reference Price
NaOH 45% is a mid-concentration liquid caustic with 1.478 g/ml density. Compared to 32%, it saves ~29% in water transportation costs while remaining liquid at room temperature — unlike 50% NaOH which may require pipeline heating in cold weather.
Main applications: textile dyeing (fabric treatment, mercerizing), intermediate chemical production, acid neutralization in processes requiring reaction heat. This balanced option suits many factories in Southern industrial parks.
NaOH 45% is gaining popularity in Vietnam due to its lower crystallization point (~+10°C vs +12°C for 50%) and better cost efficiency per kg of pure NaOH than 32%. Many textile plants in Binh Duong and Dong Nai industrial parks have switched from 32% to 45% to optimize logistics without investing in heating systems.
Liquid NaOH 50% — Applications & Reference Price
NaOH 50% is the highest concentration liquid caustic commercially available (1.52 g/ml at 20°C), mainly produced via membrane cell technology. It offers optimal logistics savings: transporting 1 ton of 50% delivers 500 kg pure NaOH vs only 320 kg with 32% — saving ~36% transportation cost per kg of actual NaOH.
However, NaOH 50% crystallizes below ~12°C. Northern factories need tank and pipeline heating systems (heat tracing) to maintain temperatures above 20°C in winter. Main applications: soap/detergent production, paper industry, chemical synthesis, NaOCl (Javen) production, oil & gas (drilling fluid pH adjustment).
Flake NaOH 99% — Applications & Reference Price
NaOH 99% flakes or pearls are white, highly hygroscopic solids. This purest form suits applications requiring high purity without water content. Standard packaging: 25kg PP/PE bags.
Advantages: long-distance transport without water weight, compact storage, flexible dilution. Disadvantages: strong exothermic reaction when dissolving (can exceed 80°C if mixed rapidly), requiring safe preparation equipment. Main applications: food industry (acidity regulator E524, food-grade NaOH required), lubricant production, laboratories, specialty chemical synthesis.

| NaOH Type | Form | Density (g/ml, 20°C) | Main Applications | Price/kg Pure NaOH |
|---|---|---|---|---|
| NaOH 32% | Liquid | 1.348 | Wastewater treatment, pH adjustment, CIP | Lowest |
| NaOH 45% | Liquid | 1.478 | Textile dyeing, intermediate chemicals | Medium |
| NaOH 50% | Liquid | 1.52 | Soap, paper, NaOCl, oil & gas | Medium-High |
| NaOH 99% | Flake/Pearl | ~2.13 (solid) | Food, lubricants, labs, synthesis | Highest |

Bulk NaOH Purchase — 5 Supplier Selection Criteria
When purchasing NaOH for factories consuming >10 tons/month, price isn’t the only factor. Wrong decisions may cause production disruptions, hidden logistics costs, and safety risks. These 5 criteria are distilled from experience serving factories in VSIP, Amata, Long Hau, and Dong An industrial parks.
Are COA/MSDS Provided Per Batch?
COA (Certificate of Analysis) and MSDS (Material Safety Data Sheet) are mandatory for every NaOH batch. COA confirms actual concentration (%NaOH, %NaCl, %Na2CO3, %Fe…) — crucial since 1-2% deviations can ruin production batches or force reformulations. MSDS is legally required under Decree 113/2017/ND-CP on hazardous chemical management.
Loc Thien provides COA/MSDS per production batch. If suppliers refuse or delay these documents — reconsider your choice.
Delivery Capacity — Dedicated Tankers?
NaOH is a strong corrosive (GHS Category C). Regular trucks can’t transport it. NaOH tankers must meet standards: 316L stainless steel or rubber-lined carbon steel tanks, spill prevention systems, ADR/TCVN hazard signage.
Practical evaluation metrics: tanker fleet size, guaranteed delivery timelines, emergency supply capability. With 20 dedicated chemical tankers, Loc Thien delivers NaOH nationwide to industrial parks including Binh Duong, Dong Nai, Ho Chi Minh City and neighboring provinces.
Competitive Bulk Pricing?
NaOH has thin profit margins and follows global Chlor-Alkali cycles. For >10 tons/month purchases, request 3-6 month framework agreements instead of spot purchases. This stabilizes production costs against market spikes.
Compare prices per kg of 100% NaOH (not solution weight). Example: 8,000 VND/kg for 32% solution equals 25,000 VND/kg pure NaOH — convert for fair concentration comparisons.
Standard-Compliant Storage?
Suppliers with compliant NaOH warehouses ensure stable supply during maintenance or market shortages. NaOH storage standards: FRP/composite or 316L stainless tanks, secondary containment, roofing, ventilation, spill response equipment.
Loc Thien’s 6 nationwide warehouses (HCMC, Binh Duong, Dong Nai, Hanoi, Da Nang, Can Tho) shorten delivery times and reduce transport costs across all regions.
Technical Support & Free Jar Testing?
For customers switching NaOH concentrations (e.g., 32% to 50%) or new applications, supplier technical support is crucial. Good suppliers will: advise concentration selection for existing equipment, calculate conversion costs (including heating systems if needed), provide free jar testing for new processes, survey factory storage tanks before first delivery.

Frequently Asked Questions (FAQ)
Can I buy small quantities under 100kg?
Loc Thien primarily serves factories and businesses with bulk needs. For orders under 100kg, please contact us for solutions matching your scale.
What’s the practical difference between 32% and 50% NaOH?
NaOH 50% saves ~36% transport costs and ~35% tank volume versus 32% for equivalent pure NaOH. However, 50% crystallizes below 12°C, requiring tank/pipeline heating in Northern winters. NaOH 32% is safer regarding crystallization, suitable for factories without heat tracing systems.
Do you deliver to Binh Duong/Dong Nai?
Yes. These are key Loc Thien service areas. With warehouses in Binh Duong and HCMC, delivery typically takes 24h for VSIP 1-2, My Phuoc 1-3, Song Than, Amata, Long Binh, Nhon Trach, Long Thanh industrial parks.
What’s the NaOH delivery timeline?
HCMC/Binh Duong/Dong Nai industrial parks: 24h. Central region (Da Nang, Quang Nam): 2-3 days. Northern region (Hanoi, Bac Ninh, Hung Yen): 2-3 days from Hanoi warehouse. Actual timing depends on order quantity and tanker schedules — confirmed upon order acceptance.
Does purchased NaOH require dilution?
Depends on application. If using 32% NaOH for wastewater treatment — use directly. If switching to 50% with 32% dosing systems — recalculate chemical feed rates (reduce ~36% metering pump flow). 99% flakes always require dissolving in water first — note strong exothermic reaction; always add NaOH to water slowly, never reverse.
Do NaOH prices fluctuate seasonally?
Yes. NaOH prices follow global Chlor-Alkali cycles, production electricity costs (~2,200-2,500 kWh/ton), and seasonal textile industry demand (peak Q2-Q3). 3-6 month framework agreements stabilize costs.
Should I buy NaOH in IBCs or tankers?
Depends on monthly consumption. For <5 tons/month — 1000L IBCs are more convenient, requiring no fixed tanks and allowing flexible positioning. For >10 tons/month — tankers save 15-20% by eliminating IBC packaging costs (deposit or purchase) and reducing transfer labor. Tankers also reduce worker chemical exposure versus manual IBC connections. Loc Thien advises tank design for customers transitioning from IBCs to tankers.
