The US government proposed placing tariffs on cement this week as part of its slowly-escalating trade war against China. The latest list will face a 10% tariff from the end of August 2018 following a consultation period. Of relevance to the cement industry, it will include limestone flux, quicklime, slaked lime, gypsum, anhydrite, clinkers of Portland, aluminous, slag, supersulfate and similar hydraulic cements, white Portland cement, Portland cement, aluminous cement, slag cement, refractory cements, additives for cement, cement based building materials and more.

At face value it seems unlikely that the tariffs will do much direct damage to the cement sectors in either China or the US. United States Geological Survey (USGS) data reports that the US imported 2Mt of cement and clinker from China in 2017 out of a total of 13.6Mt of imports. China was the third-largest exporter of cement to the US after Canada and Greece. Given the mammoth size of the Chinese cement industry - it sold 2.3Bnt in 2017 according to National Bureau of Statistics of China - it is unlikely that losing this export stream will cause the sector to lose much sleep. If the exports are coming from smaller producers though it might well impact upon them disproportionally. Any potential shortfall in the US is likely to be met by any number of the world’s overproducing cement nations. Vietnam, Iran (!) and Indonesia are the first few candidates that spring to mind.

The other point to consider from the USGS data is that the value of the cement imported from China in 2017 was on the cheaper side. Altogether the value of Chinese imported cement came to US$132m in 2017. Yet it was the fifth cheapest for cost, insurance and freight per tonne out of 32 importing countries. Add a 10% tariff to that and it is still only the eighth cheapest. If these figures represent reality then it seems unlikely that tariffs will cause the Chinese imports to slow down much.

All of this pretty much fits the general impression of China as a country that produces the most cement in the world but it actually exports very little of it. Consultancies like Ad and Marcia Ligthart’s Cement Distribution Consultants have made a point of downplaying China’s export market in recent years due to a lack of deep water terminals for plants and a general inward focus. Yet the sheer amount of production capacity could have big implications if it ever does get properly connected to the sea.

Other products facing the new tariffs that have relevance for the cement industry include input materials like gypsum or secondary cementitious materials (SCM) like slag and fly ash. Gypsum isn’t likely to be a concern given the presence of established exporters in Canada, Spain, Thailand, Oman and the like. SCMs are more mercurial but don’t appear to be too intrinsic to the US market. Ferrous slag imports grew to 2Mt in 2015 according to USGS data but the main sources were Japan, Canada, Spain and Germany. Charles Zeynel of ZAG International at the Global Slag Conference 2018 posited that Chinese exports comprised up to 6Mt or 25% of the world market of traded international slag.

All of this suggests a symbolic nature to the US tariffs on Chinese cement and related products. Perhaps the real news story to have noted this week was the framework agreement signed between Denmark’s FLSmidth and China’s China National Building Material (CNBM), the world’s largest cement producer and one of its larger cement equipment manufacturers.

Typically many of the new cement plant projects Global Cement has reported upon recently involve a Chinese contractor that may or may not be using European engineering from companies like FLSmidth who previously would have been managing the build themselves. The point here is that new plants, production lines and upgrades at US cement plants might well be built by a Chinese company through its European partners. The new upgrade to Lehigh Hanson’s Mitchell plant in Indiana has been budgeted at US$600m. This is far more than the value of Chinese cement imported into the US in 2017.
