For Q4 caustic soda purchases, use regional stock data to check whether the assumptions behind your sourcing plan remain current. Establish the supplier’s flake availability and delivered price through a quotation.

This briefing uses information retrieved on 3 October 2026. The reporting month is August, so it does not describe October inventory.

What the August figures show

Euro Chlor published its August 2026 chlorine production report on 2 October. The report covers the EU-27, Norway, Switzerland and the UK.

Reported caustic soda stocks were:

  • August 2026: 183,079 tonnes.
  • July 2026: 198,553 tonnes.
  • August 2025: 252,609 tonnes.

Stocks therefore fell by 7.8% from July and were 69,530 tonnes below the same month a year earlier. Calculated from the published totals, the annual reduction was approximately 27.5%.

How to use the figures in a purchasing decision

A lower aggregate stock figure does not identify which supplier has the product you need, or explain the movement by itself. The release does not provide a flake-specific stock figure or a transaction-price series. It cannot establish a price increase, a shortage of your required grade, or a delivery commitment.

The useful next step is to test your own procurement assumptions. If a purchase plan relies on a standing quotation, confirm that its price and delivery window are still valid. If it relies on buying only when stocks run low, check the lead time for the actual product and destination.

Avoid changing an order quantity solely because one regional indicator moved. First compare the consequence of a later delivery with the cost and practical constraints of holding more material.

Ask for a quotation that resolves the uncertainty

For an existing or alternative supplier, request a written answer to four questions:

  • What exact grade and product form does the quotation cover?
  • What quantity can be committed, and for which dispatch window?
  • What is the quotation’s validity period, and which charges are included?
  • Which documents and conditions must be agreed before the order is confirmed?

A requested arrival date and a confirmed dispatch date are different planning inputs. Keep both visible when comparing offers, and ask the supplier to identify any delivery assumptions that remain open.

For the detailed specification and documentation questions, use the existing caustic soda flakes buyer checklist.

Compare offers on the same basis

Before deciding that one offer is cheaper, align quantity, grade, product form, packaging, delivery point and commercial terms. Record any remaining difference instead of hiding it in a single price comparison.

For example, an offer that excludes destination handling cannot be compared directly with one that includes delivery to your site. Put those costs on a common basis and mark any estimate that still needs confirmation. The export documentation and Incoterms guide can help frame that discussion.

This approach turns a market report into a practical purchasing check: whether the quotations behind your plan still meet your requirements.

What to watch next

Use the next available release to see whether the reported direction persists. Record the measurement month separately from the publication date, and compare the same geographic coverage and units.

Alongside that regional series, track the evidence specific to your purchases: quote validity, agreed dispatch windows, delivered-cost components and confirmed order conditions. Those records are needed before changing a buying plan.

PANTEX’s caustic soda flakes enquiry page provides the product enquiry route. To request a proposal, send the specification, quantity and destination through the quotation page. Product availability and commercial terms must be confirmed for the individual enquiry.

Source and calculation note

Stock quantities use the source’s stated unit, tonnes; no product-form or concentration conversion has been applied.

The annual percentage change is calculated as (183,079 − 252,609) ÷ 252,609 × 100, rounded to one decimal place. The purchasing questions in this briefing are editorial recommendations, not forecasts from Euro Chlor.
