USA calcium Carbonate powder markets firmed through March as tight prompt availability and multi-sector demand supported pricing. Weekly data show prices rising 1.45% in the week ending March, extending a month-long uptrend, with March-on-month benchmarks higher by around four percent, according to ChemAnalyst. Early March demand was steadier, but mid- to late-month buying from plastics and paper/packaging users—coupled with substitution dynamics and energy-cost pressure—prompted distributors to secure prompt volumes. Overall sentiment remained constructive into late March, with order books deep and spot tonnes scarce from trading desks. Demand across core end-uses underpinned the March rise for calcium carbonate food grade used in the US Gulf region. The plastics sector remained the strongest, with on-machine PCC and GCC-filled plastics absorbing substantial volumes; paper and packaging, notably corrugated packaging tied to e-commerce, also supported consumption. ChemAnalyst notes plastics account for roughly 56% of demand and paper/packaging about 35%. Outlook suggests prices stay firm into the week, barring energy or logistics relief.
