China APT — ammonium paratungstate — is the benchmark intermediate that ultimately sets the floor under every tungsten carbide price globally, including India’s. This week’s numbers: domestic spot ¥590,000/mt, long-term contract ¥600,000/mt for H1 September, and Rotterdam APT (the export-facing international benchmark) at $3000/mtu.
Spot Below Contract — What It Signals
China’s APT spot price sitting below the long-term contract price signals near-term oversupply or soft demand relative to what producers locked in earlier — APT operating rates are currently running below 70%, reinforcing a cautious supply picture. When spot trades below contract for an extended period, it typically precedes downward pressure on scrap and carbide prices as well, which is consistent with India FOB’s break below its $115/kg floor this week.
What Indian Sellers Should Take From This
APT is upstream of everything Indian sellers deal in — drill bits, inserts, rods, mixed scrap. A softening APT market historically drags India FOB down with a one-to-two-week lag. If China APT keeps trading spot-below-contract into next week’s assessment, expect India FOB to stay under pressure rather than snap back to $115.
What Buyers and Exporters Should Take From This
Softer APT plus a lower India FOB widens the arbitrage against Chinese WC powder FOB ($165-170/kg) — Indian-origin material gets relatively cheaper to source even as China’s own input costs ease. See Exporters & Buyers for sourcing and documentation.
