Deformed rebar procurement in mid-2026 is anchored by Chinese mills concentrated in Hebei, listing HRB335, HRB400 and HRB500 grades in 6mm-32mm diameters on GB, BS4449 and ASTM A615 cross-standards, with monthly supply capability quoted up to 100000 m.t. and Tianjin as the dominant FOB loading port [S2][S8][S9].
Alibaba alone indexes 2119 suppliers matching "steel deform bar," and Okorder carries parallel listings on hot-rolled deformed bars with worldwide shipping [S1][S4]. For a buyer running a tender, that means the realistic shortlist is 5-10 Hebei/Tianjin mills plus 1-2 trading houses, not a fragmented long tail.
Grade and Standard Crosswalk Sourcing Decision
HRB400 deformed bars at 10mm-32mm diameter and 6M/12M stock length carry a 25 m.t. minimum order and 100000 m.t./month supply capability from Hebei origin, with stated advantages of exact size, regular package, and stable chemical and mechanical properties [S8]. HRB335, HRB400 and HRB500 cover the Chinese GB system, while B500A/B500B/B500C and G460B fill the BS4449 slot and GR40/GR60 fill the ASTM A615 slot — all listed on a single product card covering 6mm-20mm diameter [S2].
ASTM A615 / BS4449 standard deformed steel rebar is offered with technique options of hot rolled, cold rolled, cold drawn, ERW, forged and saw, certified to UL, BSI, ISO, SGS, BV, IBR, RoHS, CE and API, against a 100 m.t. MOQ and 10000 m.t./month supply [S9]. Cross-standard dual-listing (GB + ASTM + BS on one datasheet) is now the default format on Chinese B2B platforms, so a spec engineer can compare on a single page rather than running parallel RFQs. For process engineers mapping this to machinery selection, rebar benders and rebar cutters are the downstream equipment classes sized to the diameter bands above.
Diameter Range, MOQ and Lead-Time Levers
High-tensile deformed rebar 10mm-32mm ships from Tianjin on TT or LC terms with a 1000 m.t. minimum and 5000 m.t./month supply capability, versus the HRB400 25 m.t. / 100000 m.t. profile from the same port [S3][S8]. The 40x swing in MOQ between two Tianjin-shipping mills is the single biggest variable in any bulk-inquiry scenario; the smaller-MOQ mill is typically the right first call for a project under 500 m.t.
Diameter coverage splits cleanly: 6mm-20mm for general-purpose HRB335/HRB400/HRB500 and B500A/B500B/B500C listings [S2], 10mm-32mm for the higher-tensile construction-material grade [S3], and 10mm-32mm for the HRB400 specific card [S8]. A buyer needing sub-10mm bar (e.g. 6mm/8mm stirrup ties) has a narrower supplier set and should anchor the RFQ to the GB standard 6mm-20mm datasheet [S2]. Rebar threading machines sized to 32mm bar are the matching equipment class when the project calls for mechanical splice connections rather than laps.
Mill Geography, Port Logistics and Payment Terms
Hebei is the consistent declared place of origin for HRB400 10mm-32mm product, with Tianjin as the FOB loading port and TT or LC as the two accepted payment instruments [S8]. The same Tianjin loading port recurs on the HRB400/HRB500 GB-standard card and on the high-tensile 10mm-32mm card, indicating a single logistics corridor for roughly the entire North-China deformed-bar export trade [S2][S3].
Alibaba's "Steel Deformed Bar / Steel Rebar Reinforced Concrete for Construction Iron" supplier pool is anchored in Shandong Liaocheng, which is the second major Chinese rebar cluster alongside Hebei [S4]. The combined Hebei + Shandong geography gives a buyer two realistic port-corridor options: Tianjin (North) and Qingdao (East), both of which support standard 20-40 ft containerized and break-bulk shipments. Rebar couplers and rebar straighteners are the consumable-equipment pair that travels with the bar to site.
Price Discovery, MOQ Tiers and Spot vs Contract
Okorder lists "Ref Price: Loading" on the HRB400 10mm-32mm, high-tensile 10mm-32mm, and ASTM A615/BS4449 cards — the platform intentionally withholds the spot figure and forces an RFQ [S3][S8][S9]. This pattern is consistent across all five Okorder deformed-bar listings reviewed, which means public price discovery on Chinese B2B platforms is effectively closed; the only public number is the platform's own "worldwide shipping" service-pledge framing [S1].
The actionable price-discovery lever is therefore the MOQ ladder: 25 m.t. for HRB400 [S8], 100 m.t. for ASTM A615/BS4449 [S9], and 1000 m.t. for high-tensile 10mm-32mm [S3]. Buyers in the 25-100 m.t. band should default to the HRB400 supplier; the 100-1000 m.t. band fits ASTM A615/BS4449 cards; anything above 1000 m.t. needs the high-tensile construction-material mill plus a parallel Hebei source for buffer stock. Rebar page on the encyclopedia side covers the upstream material spec logic.
Comparison Matrix: 3 Supplier Tiers by Diameter, MOQ, Supply and Standard
Tier-1 — HRB400 Hebei mill: 10mm-32mm diameter, 6M/12M length, 25 m.t. MOQ, 100000 m.t./month, GB HRB400 standard, Tianjin FOB [S8]. Tier-2 — ASTM A615/BS4449 multi-standard mill: 10mm-32mm diameter, 100 m.t. MOQ, 10000 m.t./month, dual ASTM A615 + BS4449 certification, Tianjin FOB, technique options spanning hot-rolled to forged [S9]. Tier-3 — High-tensile 10mm-32mm construction-material mill: 10mm-32mm, 1000 m.t. MOQ, 5000 m.t./month, GB-family, Tianjin FOB [S3].
The decision criteria are: (1) diameter coverage — Tier-2 and Tier-3 tie at 10mm-32mm vs Tier-1's same band; (2) MOQ flexibility — Tier-1 wins at 25 m.t., 40x lower than Tier-3; (3) monthly supply ceiling — Tier-1 wins by 10x over Tier-3 (100000 vs 5000 m.t.); (4) standard breadth — Tier-2 wins with ASTM + BS + ISO + CE + API coverage. A buyer on a single-standard GB project should default to Tier-1; a buyer shipping to a BS4449 or ASTM A615 jurisdiction should route to Tier-2; a buyer above 1000 m.t./month on pure construction-grade steel should split between Tier-1 and Tier-3.
Verification, Mill Audits and Cross-Reference with the 2026 Sourcing Article
Third-party certification coverage on the ASTM A615/BS4449 card explicitly lists UL, BSI, ISO, SGS, BV, IBR, RoHS, CE and API as available marks [S9]. Of these, BSI and ISO are the two that a Western buyer's QA team will actually inspect; SGS and BV are the two Mllテール-survey-grade third parties commonly accepted on LC documents. A mill claiming GB-only output should still be asked for an SGS mill-test report (MTR) per heat, since GB HRB400 chemistry is typically tighter on Ceq than ASTM A615 Grade 60.
For oil-and-gas and sour-service buyers, the relevant cross-reference is the Best Deformed Rebar for Oil & Gas: Spec Bands, Sour-Service Limits, and 2026 Sourcing article, which handles the NACE MR0175 / sour-H2S overlay that the general construction-grade suppliers above do not address. A second useful cross-link for any construction buyer pairing rebar with mixing logistics is the Concrete Mixer Truck Suppliers 2026: Drum Capacity Bands, Chassis Options and Sourcing article, since rebar + ready-mix concrete is the most common paired procurement in mid-rise builds.
Failure Modes and Sourcing Risks Buyers Flag First
Three failure modes recur on the listings reviewed: (1) "Ref Price: Loading" with no public figure means a buyer cannot pre-screen on price and must burn an RFQ cycle [S3][S8][S9]; (2) MOQ 1000 m.t. is a hard wall for project-scale buyers under that threshold and forces a mill switch [S3]; (3) diameter range is the second hard wall — 6mm-20mm vs 10mm-32mm listings do not overlap, so a buyer needing 8mm stirrup ties plus 25mm main bar must run two parallel RFQs [S2][S3][S8].
A fourth, softer risk: the Alibaba "2119 suppliers" headline number counts trading houses as well as mills, and the Shandong Liaocheng origin on the index page does not guarantee a manufacturing entity behind the storefront [S4]. The 16mm-deformed-rebar manufacturer count on Made-in-China returns only 3 manufacturers with 9 products, which is a useful reality check on the Alibaba 2119 figure — the actual mill count is closer to low double digits for a single diameter [S10]. Pre-audit the supplier via SGS on-site or a third-party video mill-walk before issuing an LC.
vs 100 m.t. vs 1000 m.t. MOQ ladder that would reset the tier-1/2/3 decision above [S3][S8][S9].
