The August Price Adjustments
According to a July 30 report by Yieh Corp Steel News, Yusco increased its August selling prices as follows:
304 cold-rolled stainless steel: up by NT$1,500 per metric ton
316L surcharges: up by NT$2,500 per metric ton
430 grade: held flat
The company said the increases were necessary to offset higher input costs rather than stronger end-user demand. Standard 300-series base prices were broadly maintained, with adjustments concentrated in alloy surcharges that reflect nickel and molybdenum content.
What Is Driving the Increase
Yusco pointed to several interconnected factors behind the August decision:
Tighter Indonesian nickel supply. Indonesia, the world's largest nickel producer, has tightened mining quota controls and increased customs inspections for nickel-containing materials. The policy has delayed exports and reduced availability of nickel pig iron (NPI), the main feedstock used in stainless steel production across Asia.
Steady nickel pig iron and LME nickel prices. Although international nickel prices have softened in some periods, NPI prices have remained firm, and London Metal Exchange (LME) nickel futures have rebounded from earlier lows. This limits cost relief for stainless steel mills that purchase feedstock on spot or short-term contracts.
Weaker New Taiwan Dollar. Currency depreciation against the U.S. dollar has increased the local-currency cost of imported raw materials and energy, adding margin pressure for Taiwanese producers.
Elevated ocean freight rates. Middle East geopolitical uncertainty has pushed up shipping costs, affecting the delivered cost of raw materials and finished coil.
Yusco is not alone in facing this dilemma. Earlier in the week, market sources reported that Taiwan's major stainless mills, including Walsin Lihwa and Tang Eng, were weighing whether to raise prices to cover production expenses or hold rates steady to protect order volumes in a weak demand environment.
Market Context
Global stainless steel demand has recovered only gradually in 2026. Downstream processors and exporters continue to rely on inventory drawdown and short-term urgent orders rather than long-term restocking. Chinese stainless steel exports reached a 2026 high in June, according to industry data compiled by Stainless.club, but first-half shipments remained below year-ago levels.
The current pricing dynamic therefore reflects a supply-cost squeeze more than a demand boom. Mills are attempting to pass through raw material and logistics costs while remaining competitive in a market where buyers are price-sensitive and operating with lean inventories.
What This Means for Precision Casting Buyers
For procurement teams sourcing stainless steel investment castings, the Yusco announcement is a useful signal for August and September planning:
Expect alloy surcharges to remain volatile. 304 and 316L base prices may stay range-bound, but nickel and molybdenum-driven surcharges are likely to fluctuate with Indonesian export policy and currency movements.
Review material specifications. Where design loads allow, lean duplex or lower-molybdenum grades may offer cost stability compared with 316L. Engineering teams should evaluate whether duplex 2205, 2304, or 304 alternatives can meet corrosion and strength requirements.
Lock in raw material transparency. Work with foundries that provide spectrometer-certified chemistry reports and clear alloy surcharge mechanisms. This reduces the risk of hidden cost adjustments at invoice.
Plan for stable lead times. Supply chain friction in raw materials can extend foundry lead times if feedstock becomes constrained. Confirming rolling forecasts with key suppliers helps secure capacity.

FAQ
Why did Yusco raise prices when demand is weak?
The increases are driven by higher raw material and logistics costs, not stronger demand. Tight Indonesian nickel supply, currency depreciation, and elevated freight rates have squeezed mill margins, prompting surcharge adjustments on 304 and 316L grades.
Will stainless steel investment casting prices rise immediately?
Not necessarily. Foundry pricing depends on scrap, alloy surcharge, and feedstock purchasing practices as well as mill coil prices. Buyers should ask suppliers about their alloy cost pass-through policy and whether long-term agreements are available.
How can buyers reduce exposure to nickel and molybdenum volatility?
Options include evaluating alternative grades such as lean duplex or 304 where specifications permit, locking in material pricing with forecasts, and selecting foundries that provide transparent chemistry certification and surcharge terms.
Stay Ahead of Alloy Cost Movements
Raw material volatility makes supplier transparency more valuable than ever. Shunye Casting provides spectrometer-verified chemistry on every heat, clear material certification, and integrated silica sol investment casting plus CNC machining for valve, pump, and industrial components.
