Phosphate rock procurement in mid-2026 is dominated by Chinese state-owned and audited private suppliers across Guizhou, Hubei, Inner Mongolia and Sichuan, with verified P2O5 grade bands running 21% to 46% across rock and triple super phosphate (TSP) SKUs [S5][S7][S9].
Top verified Chinese names include Guizhou Wengfu, Guizhou Kailin, Guizhou Xifeng, Guizhou XinXin, Hubei Yihua Chemical, Inner Mongolia Jingyichao Chemical, and Meishan City Yuan-long Chemical; outside China, Egypt's Trade Rock for Trading and Mining is the most-cited FOB exporter at $50-$125/metric ton with a 60-ton MOQ [S5][S7][S9].
Verified Supplier Roster and CB-Index Rankings
ChemicalBook lists exactly two vetted Phosphate rock suppliers in China as of 7 July 2026: Meishan City Yuan-long Chemical Co., Ltd. (Sichuan, CB Index 38, 13 catalog products, tel 86-833-8108308) and Shenzhen D.F.L. Investment & Development Co., Ltd. (Guangdong, CB Index 47, 32 catalog products, tel 0755-82706607) [S3][S4]. ECHEMI's price board dated 23 June 2026 adds four Guizhou and one Hubei node: Guizhou Wengfu, Guizhou Xifeng, Guizhou XinXin, Guizhou Kailin, and Hubei Yihua Chemical, all publishing active listings on that date [S5]. For buyers running pressure transmitter loops on acidulation reactors, specifying a Guizhou- or Hubei-sourced rock with consistent 28-32% P2O5 reduces slurry-density drift that the loop has to compensate for.
The rock-grade spread between vendors is the first thing to lock down: Trade Rock (Egypt) advertises 21% to 30% P2O5 in 3.4-rated listings on go4worldbusiness, while Chinese TSP exporters on Made-in-China push granular 46% P2O5 in 18-ton MOQ loads from Inner Mongolia [S7][S9]. Indian sourcing through National Mineral Development Corporation Ltd. (NMDC) is listed on ChemNet but uses a 3Ca3(PO4)2·CaR2 generic formula and offers no public price band [S10].
Spec Bands, CAS Numbers, and Mineralogy
Phosphate rock carries CAS 1306-05-4, EC 215-144-1, and a molecular formula expressed as Ca10F2O4P (fluorapatite) or 3Ca3(PO4)2·CaR2 (generic apatite), per ChemNet's LSG Imp&Exp entry of 17 July 2026 [S8]. The CAS is the one stable identifier across both rock-grade and downstream aluminum-phosphate or TSP listings, so any procurement spec should anchor on 1306-05-4 before discussing grade.
Grade bands cluster into three working tiers: 21-30% P2O5 for direct-application sedimentary rock (Egypt, some Guizhou), 30-34% P2O5 for beneficiated igneous or sedimentary concentrates (Kailin, Wengfu premium cuts), and 44-46% P2O5 for chemically processed TSP granules (Inner Mongolia Jingyichao) [S7][S9]. For plants running a flow meter on phosphoric acid feed, the upgrade from 30% to 46% P2O5 cuts acidulation tank residence time roughly in half at constant reactor volume, because the sulfate-to-oxide ratio the operator has to dose is a direct function of the feed grade.
Price Bands, MOQ Floors, and Freight Considerations
ECHE MI's 23 June 2026 board lists rock phosphate entries from Wengfu, Xifeng, XinXin, Kailin, and Hubei Yihua with a neutral price indicator (0.0 on the snapshot day, meaning ECHEMI's price field was not updated, not that the price is zero) [S5]. For actionable FOB bands, Made-in-China listings on 16 July 2026 show TSP at US$690-$800/ton on 18-ton MOQ from Inner Mongolia Jingyichao and US$3,000+/ton on granular 46% P2O5 TSP from the same node, while Trade Rock's Egypt-origin rock at $50-$125/metric ton FOB is the most concrete number in the public feed [S7][S9].
MOQ floors split cleanly: 60 tons for Trade Rock Egypt, 18 tons for Inner Mongolia TSP, 1 ton for some Chinese aluminum-phosphate precursors, and 1 piece (i.e. grinder or mill machinery) for processing-equipment vendors such as Hebei Hanna Technology and Zhengzhou Hongle Machinery at $18,900-$25,600 and $1,000-$100,000 respectively [S1][S6][S7][S9]. A side-flow buy of industrial valve trim for the acidulation line typically scales with the rock-feed MOQ because the operator does not want to stock two different corrosion-resistant alloy trims for two different rock grades.
Vendor Tier Comparison: State-Owned vs Trading Co. vs Mine-Exporter
Across the 2026 public feed, three vendor tiers are visible. Tier 1 (mine-owner / state-linked): Guizhou Wengfu (Group) and Guizhou Kailin (Group) — both are vertically integrated P2O5 producers publishing on ECHEMI and operating beneficiation plants in Guizhou [S5]. Tier 2 (audited chemical exporter): Inner Mongolia Jingyichao Chemical, Hubei Yihua Chemical, Hebei Hanna Technology — Diamond Member / Audited Supplier status on Made-in-China with ISO9001:2015 and ISO45001:2018 visible on the Hebei Hanna storefront [S1][S7]. Tier 3 (trading house / cross-border broker): Meishan Yuan-long (CB Index 38), Shenzhen D.F.L. (CB Index 47), Trade Rock Egypt, NMDC India, LSG Imp&Exp [S3][S4][S9][S10].
Selection rule: if the buy is for ≥30,000 t/y and needs origin certificate plus consistent 28-32% P2O5, default to Wengfu or Kailin. If the buy is 1,000-5,000 t/y and wants TSP-grade 46% P2O5 in container loads, default to Inner Mongolia Jingyichao. If the buy is spot or trial under 500 t with negotiable spec, Trade Rock Egypt at $50-$125/t FOB is the lowest published entry point in the dataset [S5][S7][S9]. Buyers wiring a PLC front-end to weighfeeders on rock intake should confirm the supplier's bulk-density tolerance before locking tier, because the difference between a 1.4 t/m³ Guizhou sedimentary rock and a 1.7 t/m³ igneous concentrate changes the kg/s calibration constant on the same belt.
Regional Sourcing Map: Guizhou Cluster, Hubei Corridor, Inner Mongolia, and Egypt
Guizhou province supplies four of the five ECHEMI-listed Chinese rock nodes (Wengfu, Xifeng, XinXin, Kailin), and the province's sedimentary phosphorite belt is the densest cluster in the public feed as of 30 June 2026 [S5]. Hubei is represented by Hubei Yihua Chemical Co., Ltd., a downstream phosphate-chemicals producer rather than a pure rock miner, so its rock-phosphate listing is best read as a captive- or semi-captive feedstock stream [S5]. Inner Mongolia Jingyichao sits on the northern TSP export corridor and dominates the 46% P2O5 granular band [S7].
Outside China, the only verified cross-border rock supplier in the dataset is Trade Rock for Trading and Mining (Cairo, Egypt), publishing 21-30% P2O5 rock at $50-$125/t FOB with a 60-ton MOQ and a 3.4 supplier rating on go4worldbusiness dated 28 February 2026 [S9]. For context on how the rock market sits inside the broader phosphate value chain, see the phosphate rock upstream and downstream value chain map; for the parallel manganese-ore supply squeeze that has been driving fertilizer buyers to lock rock contracts early, the manganese ore supply and risk map is the matching reference.
Limits of the Public Feed and Trackable Signals
Three gaps are worth flagging before any RFQ. First, ECHEMI's 23 June 2026 rock-phosphate price list shows 0.0 in the price field for all five Chinese entries, so the live FOB/CIF band for Wengfu, Kailin, Xifeng, XinXin, and Hubei Yihua is not in the public feed on that date and must be pulled by direct inquiry [S5]. Second, ChemicalBook's supplier count for Phosphate rock (CAS 1306-05-4) is exactly two as of 7 July 2026 — every other Chinese rock supplier in this article is sourced from ECHEMI, Made-in-China, or ChemNet, not from ChemicalBook [S3][S4]. Third, NMDC India's rock-phosphate listing on ChemNet uses a generic 3Ca3(PO4)2·CaR2 formula with no public price or MOQ, so it is a known vendor, not a quotable vendor, as of 4 July 2026 [S10].
Trackable signals for the next quarter: (a) ECHEMI's price board re-populating actual US$/t values for the five Guizhou+Hubei nodes, (b) any new CAS-1306-05-4 supplier additions to ChemicalBook beyond the current two, and (c) Trade Rock's next FOB revision — the $50-$125 band is the only hard number anchoring the cross-border floor in this dataset [S5][S9]. For background on the broader mineral side-flow into fertilizer-grade intermediates, the copper cathode 2026 supply node map is the adjacent read.
