Packing and loading
Packing: 25 kg Bags, 27 Tons per 20ft Container
China caustic soda flakes are packed in 25 kg bags, loaded loose without pallets or shrink wrap, so a 20ft container takes 27 metric tons (1,080 bags) — more than a palletised load.
Bag
25 kg bags. Keep them sealed until use: caustic soda absorbs water and carbon dioxide from the air.
Container
1 × 20ft = 27 MT = 1,080 bags, floor-loaded. Minimum order is one 20ft container.
Unloading
Loose bags are unloaded by hand or onto your own pallets — plan labour and PPE at the receiving warehouse.
On arrival, store the bags dry, off the floor and away from acids — see how to store caustic soda safely.

Choose the right origin
One Supplier, Two Origins: China vs Türkiye Caustic Soda
China-origin flakes win on FOB price; Türkiye-origin cargo wins on distance to Europe, the Black Sea, the Mediterranean and North Africa. We supply both, so we can quote the origin that gives the lowest landed cost at your port.
| Factor | China origin | Türkiye origin |
|---|---|---|
| Loading port | Xingang (Tianjin) | Mersin, plus truck delivery |
| FOB price | Lower — USD 450/MT for 99% | Higher — see caustic soda price today |
| Grades | Flakes 98% and 99% | Flakes, pearls and liquid 48–50% |
| Packing | 25 kg bags, loose, 27 MT per 20ft | 25 kg bags palletised or in jumbo bags |
| Best for | Asia and East and Southern Africa — e.g. Indonesia, Kenya, Tanzania, Uganda, South Africa | Europe, Balkans, Black Sea, Ukraine, Mediterranean, North Africa |
The FOB gap can shrink or reverse once ocean freight, transit time, insurance and working capital are added, so always compare landed cost. Regional pages: caustic soda supplier Türkiye, UAE and Africa.
Market context
Why the Caustic Soda Price in China Is Lower
China is the world's largest caustic soda producer and exports its surplus. Chinese industry reports put 2025 output at about 47 million tonnes and exports at about 4.1 million tonnes, roughly 8.7% of production — which is why China export offers often set the lowest price level buyers see worldwide.
Export surplus
Shandong alone produced about 13 million tonnes in 2025 and handles most exports, mainly 50% liquid caustic soda and solid flakes. Liquid exports reached about 3.43 million tonnes in 2025, up 32% on 2024.
Coupled to chlorine and PVC
Caustic soda is made with chlorine in the chlor-alkali process. When PVC demand drives chlorine output, extra caustic soda reaches the market and prices soften — see how caustic soda is made.
Northern ports
Export cargo leaves through northern ports such as Tianjin (Xingang), Qingdao and Yantai, close to the main producing provinces.
Check import rules
Some importing countries apply trade-remedy duties or conformity schemes to specific origins. Confirm the rules for China-origin caustic soda in your country before ordering.

How to Read a Chinese Caustic Soda Price Quote
Chinese price reports and supplier quotes use a few terms that change the meaning of the number. Check the product word, the basis (实物 or 折百), the price point (出厂 or FOB) and the currency before you compare a China caustic soda price with any other offer.
| Term | Meaning | Why it matters |
|---|---|---|
| 烧碱 / 火碱 | Caustic soda (sodium hydroxide) | General word; check the form |
| 片碱 | Flake caustic soda | The product on this page; 99片碱 = flakes 99% |
| 液碱 | Liquid caustic soda (often 32% or 50%) | Much lower price per ton because it is mostly water |
| 离子膜碱 | Membrane-process caustic soda | Low salt, mercury-free production route |
| 折百 | Price on a 100% NaOH basis | Not the price per ton of solution — convert before comparing |
| 出厂价 / 送到价 | Ex-works / delivered price | Domestic, in yuan, usually including VAT |
| FOB 天津港 (新港) | FOB Tianjin (Xingang) | Export price in USD, loaded on board — our basis |
| 商检 | Export commodity inspection | Inspection before export customs clearance |
Use this when you read Chinese market reports: a domestic 片碱 price in yuan is not comparable with a USD FOB Xingang offer until you remove VAT, add inland transport and port charges, and convert the currency.
Supplier checklist
Choosing a China Caustic Soda Supplier: What to Check
A reliable China caustic soda supplier gives you a firm price on a proforma invoice, a COA for your lot, full product documents and a payment structure that protects both sides. Check these six points before you send an advance.
- Firm FOB price in writingPrice, grade, quantity, packing and loading port on a proforma invoice — not a "negotiable" listing.
- COA for the actual lotNaOH, Na₂CO₃, NaCl and Fe₂O₃ results for the cargo you receive, not a generic sample.
- TDS, MSDS, ISO and REACHDocuments your customs broker, warehouse and customers will ask for.
- Balanced payment termsPart in advance and the balance against the draft bill of lading, so you pay in full only once the cargo is loaded.
- Clear loading quantity27 MT per 20ft in 25 kg bags — check that the bag count on the packing list matches.
- A desk that answersOne contact for quote, loading date and documents, reachable by email and WhatsApp.
We meet all six. As a supplier and exporter with offices in Dubai and Ankara, we source China-origin flakes from Chinese producers and Türkiye-origin cargo from our own supply base, so you deal with one supplier for both origins.

FAQ
China Caustic Soda: Frequently Asked Questions
What is the China caustic soda price today?
On 7 November 2026, China-origin caustic soda flakes 99% are USD 450 per metric ton FOB Xingang, and flakes 98% are about USD 445–447 per metric ton FOB Xingang. Prices are reviewed regularly and confirmed on a proforma invoice.
What is the price of caustic soda in China per kg?
At USD 450 per ton FOB Xingang, China-origin caustic soda flakes 99% work out to about USD 0.45 per kg, or about USD 11.25 per 25 kg bag, before freight, insurance and import duties.
Why is caustic soda from China cheaper?
China has the largest chlor-alkali capacity in the world and produces more caustic soda than it uses at home, so producers export the surplus at competitive prices. Freight, transit time and import rules decide whether it is also cheapest once landed at your port.
Are you a China caustic soda supplier or a manufacturer?
We are a supplier and exporter, not a factory. SUHA International Trading sources China-origin caustic soda flakes from Chinese producers and handles the quotation, loading at Xingang and export documents for buyers worldwide.
Which port do you ship China caustic soda from?
China-origin caustic soda flakes are quoted and loaded FOB Xingang, the port of Tianjin in northern China.
What is the minimum order for China caustic soda flakes?
The minimum order is one 20ft container. A 20ft container carries 27 metric tons, which is 1,080 bags of 25 kg.
How are China caustic soda flakes packed?
Flakes are packed in 25 kg bags, loaded loose in the container without pallets or shrink wrap. That is how a 20ft container reaches 27 metric tons.
What are the payment terms?
Payment is by telegraphic transfer (TT): 50% in advance, and the remaining 50% against the draft bill of lading or the FOB shipping documents.
How long does it take to load an order?
Loading is scheduled once the 50% advance payment is received, so the lead time depends on when the advance arrives. The loading date is confirmed on the proforma invoice.
What documents come with China caustic soda?
Each shipment is supported by a certificate of analysis (COA), technical data sheet (TDS), material safety data sheet (MSDS), ISO certification and REACH documentation, plus the bill of lading, commercial invoice, packing list and certificate of origin.
What is the difference between caustic soda flakes 98% and 99%?
The number is the minimum sodium hydroxide content. Flakes 99% carry less sodium carbonate and moisture and suit chemical, textile and water-treatment users with tight specifications; flakes 98% cost a few dollars less and suit soap, detergent, cleaning and general industrial use.
Is Chinese caustic soda good quality?
Quality depends on the producer and the lot, not the country. Ask for a COA on every lot, compare NaOH, sodium carbonate, sodium chloride and iron against your specification, and use pre-shipment inspection for first orders.
Is China or Türkiye caustic soda better for my country?
China-origin flakes usually have the lower FOB price, while Türkiye-origin cargo has shorter transit to Europe, the Black Sea, the Mediterranean and North Africa, plus truck delivery. Compare the landed cost at your port, not the FOB price alone.
Does the FOB Xingang price include packing?
Yes. The FOB Xingang price per metric ton includes the 25 kg bags and loading on board the vessel at Xingang. Ocean freight, insurance and import costs at destination are paid by the buyer.
Are Chinese domestic caustic soda prices the same as export prices?
No. Chinese market reports quote domestic prices in yuan per ton, usually ex-works or delivered and including VAT, and liquid caustic soda is often quoted on a 100% NaOH basis. An export FOB price in US dollars per metric ton is a different number, so compare like with like.
What does 片碱 mean on a Chinese caustic soda quote?
片碱 (piàn jiǎn) means flake caustic soda, the solid flake form of sodium hydroxide. 烧碱 or 火碱 is the general word for caustic soda, 液碱 is liquid caustic soda and 离子膜碱 means membrane-process caustic soda.
What is the HS code for caustic soda flakes from China?
Solid caustic soda flakes are classified under HS 2815.11. They ship as UN 1823, Class 8, packing group II.
