Liquid Caustic Soda Lye 32% / Sodium Hydroxide Lye 32% Bulk Import: Specs, Drums and Cost per Ton
Liquid Caustic Soda Lye 32% / Sodium Hydroxide Lye 32% bulk import guide: specs, drum sizes, Class 8 shipping and the true cost per ton of NaOH.

Planning a Liquid Caustic Soda Lye 32% / Sodium Hydroxide Lye 32% bulk import? Liquid caustic soda is one of the most widely used industrial bases, but buying it well means looking past the headline price to concentration, drum size, corrosive-goods shipping and the real cost of the sodium hydroxide you receive.

What Liquid Caustic Soda Lye 32% Is and Why Buyers Choose It
Liquid caustic soda lye is a water solution of sodium hydroxide (NaOH, CAS 1310-73-2). At 32% it is a clear, colourless, strongly alkaline liquid that can be pumped and dosed directly, with no dissolving step and none of the heat released when solid caustic is mixed with water.
Buyers choose the 32% strength for several practical reasons:
- it is ready to use for pH adjustment and neutralisation in water and effluent treatment;
- it is a common strength for cleaning-in-place (CIP) in dairy and food plants;
- it regenerates anion exchange resins in demineralisation units;
- it serves soap, detergent, textile, pulp and paper and oil refining processes;
- it stays liquid in cooler conditions where stronger 50% lye can crystallise.
If your plant already dilutes stronger caustic on site, compare it with Liquid Caustic Soda Lye 50% before you decide.
Liquid Caustic Soda Lye 32% / Sodium Hydroxide Lye 32% Specifications to Confirm
Ask every supplier for a specification sheet and a certificate of analysis (COA) per lot covering at least:
| Parameter | What buyers usually request | Why it matters |
|---|---|---|
| NaOH content | 32% by weight, with a stated tolerance | Sets how much active caustic you pay for |
| Sodium carbonate (Na2CO3) | Low, stated as a maximum | Forms when lye absorbs CO2; reduces strength |
| Sodium chloride (NaCl) | Low, stated as a maximum | Chloride matters in boilers, stainless steel and food use |
| Iron (Fe) | Low ppm level | Iron can discolour products |
| Density at 20 °C | About 1.35 g/cm³ | Converts tank litres into kilograms of product |
Grades made by the membrane cell process usually have lower chloride than older processes. Values above are typical, not guarantees; always check them against the COA for your lot. The PubChem sodium hydroxide record is a useful reference for physical and hazard data.

Liquid Caustic Soda Lye 32% / Sodium Hydroxide Lye 32% Price: Calculating the Real Cost per Ton
Our current Liquid Caustic Soda Lye 32% / Sodium Hydroxide Lye 32% price is shown in the key facts table above. Because the product is 68% water, the most useful comparison is the cost per ton of 100% NaOH. Divide the price per metric ton of solution by 0.32: at our list price of USD 295 per ton of lye, that works out to roughly USD 922 per ton of sodium hydroxide on a dry basis.
Use the same calculation for every offer you receive, including caustic soda flakes 98% or caustic soda pearls 99%. Then add:
- Freight. With lye you also ship the water, so sea freight per ton of NaOH is higher than for flakes or pearls.
- Packaging. Drums add cost per ton compared with bulk tanks, but most importing sites need them.
- Handling on site. Solid caustic needs dissolving equipment, labour and safety controls; liquid lye avoids that.
- Import duty and local charges at your destination.
How to Buy Liquid Caustic Soda Lye 32% / Sodium Hydroxide Lye 32% in Drums
We supply the 32% lye in 250 kg and 500 kg plastic drums. At a density of about 1.35 g/cm³, a 250 kg drum holds roughly 185 litres. When you buy Liquid Caustic Soda Lye 32% / Sodium Hydroxide Lye 32% in drums, plan for:
- chemical-resistant drum pumps or a transfer system rated for strong alkalis;
- a bunded, covered storage area away from acids, aluminium, zinc and other incompatible metals;
- keeping drums sealed, because caustic absorbs carbon dioxide from air and slowly loses strength;
- full protective equipment, including face shield, gloves and eye-wash stations near the point of use.
Sodium hydroxide solution ships as dangerous goods: UN 1824, Class 8 (corrosive). Your SDS, labels and dangerous-goods declaration must match. Our logistics and shipping team prepares these with the shipping line.
Choosing a Liquid Caustic Soda Lye 32% / Sodium Hydroxide Lye 32% Wholesale Supplier for Bulk Import
A dependable Liquid Caustic Soda Lye 32% / Sodium Hydroxide Lye 32% wholesale supplier should give you, in writing, the concentration and its tolerance, impurity limits, packaging type, container load, Incoterm and the documents that travel with each shipment: COA, SDS, packing list, commercial invoice, bill of lading and certificate of origin where needed.

Frequently asked questions
What is the difference between 32% and 50% caustic soda lye?
Both are sodium hydroxide solutions. 50% lye carries more NaOH per ton shipped but can crystallise in cool conditions, while 32% stays liquid at lower temperatures and is often closer to the strength used on site.
How do I compare lye prices with caustic soda flakes?
Convert every offer to cost per ton of 100% NaOH. For 32% lye, divide the price per ton of solution by 0.32, then add freight and handling.
Is Liquid Caustic Soda Lye 32% dangerous goods?
Yes. Sodium hydroxide solution ships as UN 1824, Class 8 corrosive, with the safety data sheet and correct labelling.
What packaging is available?
We currently offer 250 kg and 500 kg plastic drums. Confirm the container load and palletising in your quotation.
