As of September 2026, grain-oriented electrical steel (GOES) for transformer cores is quoted at US$4.29/kg in North America and US$1.63/kg in Europe, both unchanged month-on-month, while Northeast Asia tracks US$2.31/kg on the BusinessAnalytiq index [S3]. The 2.6:1 North-America-to-Europe spread is the single largest sourcing variable procurement faces in 2026.
Non-oriented electrical steel (NOES, also called NGO or NGOES) is the motor-grade sibling: a different silicon level, a different crystallographic texture, and a different trade status. On 1 December 2025 the U.S. International Trade Commission instituted five-year (sunset) reviews of the antidumping duty orders on NOES from China, Germany, Japan, South Korea, Sweden, and Taiwan [S1]. The two grades are NOT interchangeable, and the 2026 procurement playbook is shaped by that fact.
Price snapshot, October 2026
GOES spot index values from BusinessAnalytiq show North America at US$4.29/kg, Europe at US$1.63/kg, and Northeast Asia at US$2.31/kg, all flat versus August 2026 [S3]. The North America figure is roughly 2.6x the Europe figure for the same commodity, a gap that owes more to mill footprint, anti-dumping coverage, and shipping lanes than to underlying metallurgy. Fry Steel's 2026 reference puts the global electrical-steel market (GOES + NGOES combined) on a path from approximately US$36B in 2024 to over US$51B by 2030 [S8], which is consistent with the GMI estimate of US$21.72B for 2026 alone when measured at a tighter product scope [S4]. MetalMiner publishes parallel regional GOES benchmarks for the United States, China, Europe, and Japan, and is the only OEM-approved price reporting agency for the grade [S2].
For NGOES, the pricing reference list is thinner; most publicly quoted indices roll GOES and NGOES together, and the dominant 2026 signal on the NGOES side is regulatory rather than spot. If your 2026 BOM is NGOES and your plant is in the United States, the binding constraint is duty rate, not index price.
How the two grades differ at the spec level
GOES is silicon-iron (about 3 to 4 percent Si) processed so that crystal grains align with the rolling direction, giving high permeability and low hysteresis loss along that axis [S3]. It is the material of choice for power and distribution transformer cores, where flux travels in one defined direction. NGOES has a randomized grain texture, so its magnetic properties are isotropic in the plane of the sheet; that is exactly what rotating machines (induction motors, EV traction motors, industrial servos) need. NGOES is also typically supplied in thinner gauges with tighter lamination coatings, and its chemistry is tuned for higher-frequency loss rather than directional permeability.
Substituting one for the other is a real engineering failure, not a paper one. GOES in a motor lamination stack wastes material in the transverse direction; NGOES in a transformer core raises no-load loss by tens of percent and pushes the unit out of its efficiency class. Specification discipline here starts with the part drawing, not the purchasing system.
The two demand drivers in 2026
GOES demand is paced by transformer orders, which in turn track grid capex. GMI's 2026 dataset puts annual global grid spending at approximately US$400B, with the IEA projecting that figure must rise by roughly 50 percent by 2030 to keep pace with electricity demand growth [S4]. GMI also reports global power-transmission investment at US$140B in 2023, up 10 percent year-on-year, with advanced economies and China accounting for about 80 percent of the total [S4]. Technavio's 2026-2030 outlook flags a concrete downstream symptom: transformer lead times for premium GOES have stretched past 18 months, a direct consequence of demand outrunning qualified mill capacity [S5].
NGOES demand is paced by electric motors. The automotive end-user segment accounted for the largest NGOES revenue share in 2024, and APAC represented 75.5 percent of the 2024-2030 growth pool [S5]. For context on how that flows into motor bill-of-materials, the 2026 Electric Motor Pricing breakdown maps NGOES, copper, and the other dials a motor buyer actually negotiates. GOES demand growth is forecast at 5.1 percent CAGR (Grand View) [S6] to 6.35 percent CAGR (GMI) [S4], while Technavio's wider electrical-steel combined forecast sits at 11.8 percent CAGR through 2030, reflecting how much faster the motor-grade NGOES volume is scaling relative to the transformer-grade pool [S5].
U.S. trade action that matters for NGOES buyers
The Federal Register notice of 1 December 2025 instituted the five-year (sunset) reviews on NOES from China, Germany, Japan, South Korea, Sweden, and Taiwan under the Tariff Act of 1930 [S1]. Procedurally, the U.S. International Trade Commission will vote on whether revocation of the existing antidumping duty orders would lead to recurrence of material injury within a reasonably foreseeable time. The institution itself does NOT change duty rates; it starts the clock on a review that typically concludes with either continuation, continuation with revised rates, or revocation. For U.S. buyers, the practical effect is that 2026 sourcing contracts written on Chinese or German NOES continue to carry the existing AD/CVD cash deposit, and any decision on rate revision is a 2027 event. None of the rates are stated in the institution notice itself [S1].
For European buyers, the trade picture is different: the European Commission has had its own safeguard and anti-dumping instruments active on certain steel categories, and several EU mills (Thyssenkrupp Steel Europe is among the GMI top-5 by 2025 share [S4]) supply into the regional NGOES pool, which helps explain the structurally lower European GOES index price relative to North America [S3].
Selection matrix: GOES vs NGOES by application
Decision criteria for specifying electrical steel, grounded in the 2026 data: magnetic anisotropy, operating frequency, mechanical stamping behaviour, and trade-duty exposure. [S3]
GOES (Grain-Oriented): best for 50/60 Hz power and distribution transformer cores, large generators, and any application where flux travels along a defined axis. Core loss is the lowest of any mainstream electrical steel in that axis. Weak in rotating machines, where the off-axis loss is high. North American supply is concentrated, duty-protected, and currently the highest-priced regional benchmark at US$4.29/kg [S3]. Lead time for Hi-B and laser-scribed grades exceeds 18 months on spot order books [S5].
NGOES (Non-Oriented, also called NOES): best for EV traction motors, industrial induction motors, hermetic compressor motors, and any rotating machine. Isotropic in-plane magnetic properties are exactly what rotating flux needs. Heavily exposed to U.S. antidumping duty orders covering six source countries [S1]. APAC-dominant supply, with China, Japan, and South Korea together accounting for the bulk of global tonnage; the global market reached an estimated 13,900 kt in 2025 according to GMI's producer and OEM checks [S4]. For the steel grade families that sit alongside NGOES on a motor BOM, the stainless-sheet per-kg pricing reference and the 304 vs 316 scrap price snapshot are useful adjacent reads on the wider flat-steel cost stack.
Cross-grade rule: if flux rotates, do NOT specify GOES. If flux is unidirectional, do NOT specify NGOES. Specifying the wrong grade does not just cost money; it fails the efficiency class.
Who each grade is for, and who it is not for
GOES is for: transformer OEMs building power and distribution units for grid reinforcement, HVDC interconnect, and renewable tie-in projects; large hydro and turbo generators; any specifier who needs Hi-B or domain-refined steel for ultra-low no-load loss. GOES is NOT for: motor laminations, EV traction, low-cost consumer appliances, or any application where the part will be stamped into a complex shape that forces flux off the rolling axis. [S4]
NGOES is for: automotive traction motor and industrial motor OEMs; motor-grade stampers running high-speed presses on 0.20-0.35 mm gauge; specifiers chasing IE4 and IE5 efficiency classes under IEC 60034-30-2 (this standard governs motor efficiency classes, not the steel itself, and the steel selection flows from the class target, not the reverse). NGOES is NOT for: power transformer cores; large hydro generators; any specifier who has not checked the U.S. AD/CVD cash deposit rate for the source country on their 2026 PO.
Procurement signals to track in late 2026 and into 2027
Three trackable signals for the rest of 2026: the U.S. International Trade Commission's preliminary and final determinations in the NOES five-year reviews, which will dictate 2027 AD/CVD cash deposit rates on the six covered source countries [S1]; the GMI-forecasted move toward US$200B+ of annual transmission investment by the mid-2030s, which is the demand backbone under GOES pricing [S4]; and the continued narrowing of European GOES prices against the North American index, currently 1.63 vs 4.29 US$/kg, a spread that typically compresses only when European mill capacity expands or North American AD enforcement softens [S3].
For related cost-stack context that touches the same BOMs, the Electrical Equipment PPI 2026 reading is the upstream macro signal that frames whether the electrical-steel index is moving with or against the broader fabricated-metal equipment cost base. Buyers writing 2027 contracts should anchor to the U.S. AD/CVD preliminary determination date, the IEA grid-capex trajectory, and their own mill-capacity audit of the 18-month Hi-B delivery queue, in that order of priority.
