MOSCOW (MRC) -- US caustic soda exports in the first four months of 2021 declined nearly 2.4% compared with January-April 2020, reflecting continued fallout from production shutdowns forced by a deep freeze that hit the US Gulf Coast and much of the US in mid-February, reported S&P Global with reference to the latest US International Trade Commission (ITC) data.
The US shipped out 1.878 million mt of caustic soda in the January-April period, down from 1.92 million mt in the year-ago span, the data showed.
US chlor-alkali rates plunged to 59% in February, from 83% in January, when sustained subfreezing temperatures forced widespread petrochemical plant shutdowns, according to industry statistics. Caustic soda supply had been seen long before the freeze, but sudden shutdowns tightened supply.
After the freeze, caustic soda demand that had been sluggish since mid-2019 began rebounding as buyers sought to boost low inventories and growth in US COVID-19 vaccination rates spurred more economic activity.
Demand for printing paper, napkins, pint-sized milk cartons and other products made with caustic soda plunged in April 2020 when schools and offices closed, sending workers and students to work and learn from home.
US chlor-alkali rates fell to 68% in April 2020 from 90% in March that year, and remained in the low to mid 70% range from May through October. Rates surpassed 80% in November 2020 and stayed in the low 80% range until the freeze hit.
March chlor-alkali rates rose to 71% from February's 59%, and again to 80% in April, industry statistics show.
While US caustic soda exports fell slightly year on year, imports rose 8.2% to 331,297 mt from 306,027 mt in January-April 2020, the ITC data showed.
As MRC wrote before, in May 2021, American Westlake Chemical said it will soon sell "green" caustic soda, which emits 30% less carbon dioxide during its production. Westlake President and Chief Executive Officer Albert Chao said the company wants to obtain an environmental compliance certificate for the production of caustic soda using this technology in Europe. Green caustic soda has the same properties as regular sodium hydroxide. The difference lies in the use of renewable energy sources in the production process.
We remind that Russia's March production of sodium hydroxide (caustic soda) was 118,000 tonnes (100% of the main substance) versus 98,400 tonnes a month earlier. In the first quarter of 2021, overall output of caustic soda in Russia totalled 329,400 tonnes, down by 0.7% year on year.
The main caustic soda producers in the United States are Olin, Occidental Chemical, Westlake Chemical, Shintech, and Formosa Plastics.
