As of mid-2026, mainland China concentrates the largest share of the global stainless steel coil supply base, with five named manufacturers — AVIC International Mineral Resources (AVIC-MR), Tianjin Jintaishengtong Steel, Star Industrial Group, Huali Steel, and a broader Made-in-China.com factory pool of 500+ audited suppliers — publishing 200, 300, and 400-series hot- and cold-rolled coils for export under FOB terms [S1][S3][S9][S10].
Across 2026 sourcing listings, published FOB price bands for cold-rolled austenitic 304 and 316L coils sit in the US$1,000-3,000/ton range, ferritic 430/410/409 strip at US$1,050-3,000/ton, and SS301/631 high-hardness 0.1 mm strip at US$1,100-3,000/ton, with MOQ starting at 1 ton for general trading houses and 20 ton for mill-direct mill coils [S4][S6][S8].
Grade families: 200, 300, 400 series and where each fits
Stainless steel coil is classified by the AISI 200/300/400 series, and the 300 series (austenitic, primarily 304 and 316L) is the dominant export grade on mainland China sourcing listings because it combines ≥10.5% Cr with Ni-based corrosion resistance [S2][S6].
The 200 series (notably 201) is widely sold for cookware, appliance, and decorative strip applications where Ni content is partially substituted by Mn-N; AVIC-MR lists 201 hot-rolled strip and Okorder lists 201 coil with a 20 ton MOQ and 20,000 ton/month supply capability, signalling it is the high-volume, lower-cost tier [S1][S8]. The 400 series (430, 410, 409) is ferritic with no Ni; it is sourced for home appliance panels and automotive exhausts and trades at a lower price band on Made-in-China.com listings, with EN 1.4016 explicitly called out for high-chromium strip [S6].
Trade listings also show specialised 300-series variants: SS301/631 0.1 mm strip with HV 200-220 hardness for precision stamping, and 316L/316/304 8K mirror coil at 0.2 mm for elevator car panels, indicating that surface finish (2B, BA, 8K mirror, oil-mill "snow wire") is a parallel axis to grade in the supplier selection matrix [S2][S6].
Manufacturer profiles and production capabilities
AVIC International Mineral Resources (AVIC-MR) is the export arm of a 2008-restructured state-owned aviation conglomerate, reporting 500,000+ employees, 80+ patents, 90+ products, and a 20,000 m² service area, with hot- and cold-rolled coils of 200/300/400 series plus slitting, cutting, and film-covering services, shipping to India, Russia, Vietnam, Malaysia, Korea, and Turkey [S1].
Tianjin Jintaishengtong Steel Co., Ltd. operates a multi-metal trading model from Jinnan, Tianjin, holding BS 25999-2, OHSAS 18001, and ISO 9001 certifications, and lists stainless coil alongside stainless pipe, sheet, alloy pipe/sheet/coil/bar, aluminium tube/bar/sheet, copper plate/bar/strip, and brass/titanium — useful when a single PO must cover multiple non-ferrous and ferrous lines [S10]. Star Industrial Group Limited, based in Yuyao/Ningbo, positions itself specifically as a coil specialist covering hot- and cold-rolled coils plus 201/202/301/304/316/420 circles [S9].
On Made-in-China.com, the "Steel Stainless Coil Factory" product search returns audited Diamond Members, with 304, 304L, 316, 316L, 430, 201, 321, 310S, 409, 410 listed as standard mill grades under OEM brand marks such as HXH Steel, Baosteel, and Shagang [S3][S7]. Ningbo Huali Steel is a Diamond Member that publishes spring-coil SKUs at US$2,500-4,000/ton with 1 ton MOQ, and Star Industrial Group cross-trades both hot- and cold-rolled coils for the same grade set [S4][S9].
Price, MOQ, and lead-time benchmarks
Across the May-July 2026 sourcing window, the cold-rolled austenitic band of US$1,000-3,000/ton on Made-in-China.com aligns with the Okorder 201-coil listing that posts 20,000 ton/month supply capability and a 20 ton MOQ, suggesting mill-direct capacity is not the binding constraint for 200/300 series at typical project volumes [S3][S6][S8].
For higher-specification or harder tempers, the SS301/631 0.1 mm strip at HV 200-220 sits in the US$1,100-3,000/ton range, while the spring-coil sub-segment from Huali Steel commands US$2,500-4,000/ton at 1 ton MOQ — a ~150% premium over commodity 304 cold-rolled, reflecting the extra rolling passes and hardness-control steps [S4][S6]. Okorder's generic stainless coil listing publishes a 1 MT MOQ and 3,500 MT/month supply, with payment on TT or L/C, which sets the trading-house floor for single-trial orders [S2].
Price alone is a poor selector on stainless steel coil because the same nominal "304" can be 2B, BA, or 8K mirror finish, mill edge or slit edge, and 0.2-3.0 mm thickness — the elevator-decor 0.2 mm 8K listing and the structural 0.8 mm slit-edge plate-coil listing from the same platform illustrate this [S6].
Selection criteria by application
For process piping and structural stainless service, stainless steel coil that will be further welded or formed should be ordered to 304L/316L (low-carbon variants) to avoid post-weld intergranular corrosion risk, and 316/316L is the de facto marine-grade choice where Mo is required for chloride resistance [S2][S6].
For stamping and spring components, the SS301/631 0.1 mm strip at HV 200-220 published by Made-in-China.com sellers is the typical specifying pattern: 301 work-hardens to high tensile, and 631 (17-7PH) is the precipitation-hardened grade for sustained load at moderate temperature [S6]. The Huali Steel spring-coil line at US$2,500-4,000/ton with 1 ton MOQ is the right entry point for small-batch springs and spring washers [S4].
For appliance, decorative, and elevator trim, 430/410/409 ferritic strip and 8K mirror 304/316L coil dominate the listings, with EN 1.4016 explicitly used for high-chromium ferritic strip — the same grade set a buyer would cross-reference against a carbon steel substrate when a magnetic, lower-cost ferritic skin is acceptable [S6]. For applications needing magnetic or induction-heating response, 1Cr17 ferrite and 1Cr13 martensite are explicitly named as ferromagnetic, while austenitic 304/316 is non-magnetic in the annealed condition [S2].
Standards, certification, and due-diligence signals
Buyers should anchor qualification to ISO 9001 quality system certification at minimum, with the Made-in-China.com Diamond Member / Audited Supplier flag functioning as a platform-level filter; Tianjin Jintaishengtong additionally discloses BS 25999-2 (business continuity) and OHSAS 18001 (occupational H&S), which are stronger signals for projects with EPC contractor oversight [S3][S10].
For oil-and-gas, chemical, and marine end-uses where the coil will be cut into pipe or tube, ASTM A240 / EN 10088-2 mill certificates are the standard expectation, although the current research does not explicitly cite these standard numbers — buyers must request the MTC per heat and verify it against the alloy steel and silicon steel reference data the stainless steel grade set inherits from.
The Okorder generic coil listing publishes payment terms of TT or L/C at China main port, with an OKorder Service Pledge covering quality product, online order tracking, and timely delivery — useful as a baseline service-level expectation when negotiating with non-Diamond suppliers on the same platform [S2]. For buyers who also need solenoid coil components wound from stainless wire, the same factory networks (AVIC-MR, Huali, Star Industrial) typically cross-sell stainless wire, strip, and bar, allowing consolidated POs [S1][S4][S9].
Who should source from this list — and who should not
Chinese mill-direct and trading-house suppliers in this 2026 sourcing map are the right channel for OEM buyers, EPC contractors, and appliance/elevator/cookware OEMs needing 1-20 ton MOQ entry, FOB pricing, and 200/300/400 series grade coverage; they are not the right channel for buyers who require NACE MR0175 / ISO 15156 sour-service certification, nuclear-grade ASME Section III traceability, or small-lot specialty alloys outside the 200/300/400 series window. [S6]
Single-source qualification is risky: the Star Industrial Group listing shows 201/202/301/304/316/420 coverage but no published 904L, duplex 2205, or super-austenitic 254 SMO, so buyers needing those grades must source separately from specialty mills rather than the trading-house tier shown here [S9]. For commodity 304/316L strip and coil under 3 mm, the AVIC-MR + Made-in-China.com Diamond Member pool offers the deepest breadth of 2B/BA/8K surface options and the widest 1-20 ton MOQ spread, which is where most non-specialty sourcing will land in 2026 [S1][S3][S6].
For buyers running cross-category B2B procurement, the same sourcing portals that surface stainless steel coil listings also surface stainless pipe, alloy coil, and copper/brass/aluminium lines, which is the structural reason trading-house suppliers like Tianjin Jintaishengtong publish eight product categories in a single company profile rather than a single-line catalog [S10]. Cross-referencing the broader stainless steel and carbon steel encyclopedia entries before issuing the RFQ helps set the correct grade-vs-price expectation against the published US$1,000-4,000/ton band.
Trackable signals to watch through end-2026: any new SONCAP or other destination-market certification update on Made-in-China.com Diamond Member profiles, the next round of AVIC-MR product news posts (last updated within the research window on 2026-07-28), and any shift in the published US$1,000-3,000/ton cold-rolled band driven by nickel and chromium feedstock cost.
