BTR New Material Group Co., Ltd. is a Chinese lithium-ion battery-materials manufacturer and the world's largest anode-material supplier, a position it has held for 14-15 consecutive years.
Named counterparties identified by open-source research and written only where a primary source states the relationship — never inferred from sector or co-mention. 12 suppliers, 12 customer-side. This is a partial view: it covers the relationships we could evidence, not the company's full supply base.
US import bill of lading CMDUDJA1367435, arrival 2025-08-08: shipper PT Indonesia BTR New Material, Jl. Indraprasta No. 8, Kawasan Industri Kendal, Central Java, Indonesia (BTR's Indonesian anode-material plant); consignee Panasonic Energy Corporation of North America (PECNA), Olathe, Kansas; loaded Semarang, via Singapore; country of origin Indonesia; cargo '288 PACKAGES OF I-NSG17-B (SPHERICAL GRAPHITE)', net weight 144,000 kg (gross 400,882 lb). Panasonic Energy's US cell plants are in Nevada and De Soto, Kansas. Single shipment, value not stated on the bill.
Rank-1 customer at RMB 3,472,997,237.57 — name redacted as 客户一 in the customer table, but the related-party note discloses sales to SK on of the identical figure to the yuan. Same identity holds in FY2024 (RMB 3,037,863,125.75 = 21.34%). Also rank-4 SUPPLIER (供应商二, RMB 470,651,192.80 = 3.39% of procurement = raw materials 470,091,947.54 + services 559,245.26). Related because SK on holds 25.00% of BTR subsidiary Changzhou BTR New Material Technology plus a board seat, since 2022-06-30.
H1-2026 semi-annual report (filed 2026-08-28, R145 deadline pull). Sales to SK on (销售商品): RMB 2,181,127,395.40 of RMB 10,220,514,268.03 total H1-2026 revenue = 21.34%. Also a supplier: purchases from SK on (采购原材料 + 接受劳务) totalled RMB 645,403,873.45, = 7.86% of H1-2026 cost of sales (RMB 8,212,380,732.43) — a supplier-side share on a cost-of-sales basis, not directly comparable to the FY2025 note's 3.39%-of-procurement figure since procurement and COGS are different bases; recorded here as the closest available denominator in this filing. Same related-party basis as the FY2025 row (SK on holds 25.00% of Changzhou BTR plus a board seat).
H1-2025 comparative from the same H1-2026 filing. Sales to SK on: RMB 1,737,502,797.28 of RMB 7,837,646,228.04 total H1-2025 revenue = 22.17% (-0.83 pts vs H1-2026, even as SK on's absolute spend grew 25.5%, because total revenue grew faster at 30.4%). Purchases from SK on: RMB 269,463,991.00, = 4.44% of H1-2025 cost of sales (RMB 6,066,650,863.45).
RMB 1,218,800,603.66 (FY2024: 935,805,487.97), up 30% year on year. Named in the related-party note but NOT in the top-5 table — it sits just below rank-5 (客户六, RMB 1,311,714,136.22), which is a coherence check on the whole reading. Related via EVE subsidiary EVE Asia holding 24.00% of Changzhou BTR plus a board seat.
H1-2026 semi-annual report (filed 2026-08-28, R145 deadline pull). Sales to EVE Energy (销售商品): RMB 1,101,140,296.51 of RMB 10,220,514,268.03 total H1-2026 revenue = 10.77% — up sharply from the FY2025 annual rate of 7.18%, and EVE now outranks SK on's H1-2026 growth rate (EVE +124.5% YoY vs SK on +25.5% YoY on the same comparative base). Related via EVE subsidiary EVE Asia holding 24.00% of Changzhou BTR plus a board seat, same basis as the FY2025 row.
H1-2025 comparative from the same H1-2026 filing: RMB 490,502,488.30 of RMB 7,837,646,228.04 total H1-2025 revenue = 6.26%.
Rank-2 customer, RMB 2,662,312,268.32. Name exempted by the filer, figure disclosed. code_stability=proven-across-vintages: FY2025's top five are 客户一/二/三/五/六 — 四 is absent and 六 is new, which is only possible if each code pins to an entity rather than to a rank; and 客户一 is independently identified as SK on in BOTH FY2024 and FY2025 by matching the related-party note to the yuan.
Rank-3 customer, RMB 1,605,512,896.08. Name exempted by the filer, figure disclosed. code_stability=proven-across-vintages on the same evidence as 客户二 (non-contiguous code set 一/二/三/五/六 across two filings).
Rank-4 customer, RMB 1,550,535,387.29. Name exempted by the filer, figure disclosed. Read the code as an entity id, not a rank: 客户五 is the FOURTH-largest customer in FY2025 — the numeral and the rank do not agree, which is itself the evidence for code_stability=proven-across-vintages.
Rank-5 customer, RMB 1,311,714,136.22 — new to the top five in FY2025. Name exempted by the filer, figure disclosed. code_stability=proven-across-vintages on the same non-contiguous-code evidence. Coherence check: named related party EVE Energy sits just BELOW this threshold at RMB 1,218,800,603.66.
Associate. Toll processing (委托加工) RMB 143,101,531.31 plus raw materials RMB 1,799,096.53 — the largest of BTR's contract-graphitisation associates.
H1-2026 semi-annual report (filed 2026-08-28, R145 deadline pull). Toll processing (委托加工) RMB 116,442,028.98 plus raw materials RMB 568,665.17 (H1-2025 comparative from the same filing: toll processing RMB 53,317,855.51, raw materials RMB 1,312,219.55 — toll-processing spend roughly doubled year on year).
Associate. Toll processing RMB 127,528,896.17 plus raw materials RMB 5,769,158.03. Ningxia is a coal-power graphitisation hub — this is the energy-intensive step of the anode chain.
H1-2026 semi-annual report (filed 2026-08-28, R145 deadline pull). Toll processing RMB 61,834,801.21 plus raw materials RMB 11,974,245.09 (H1-2025 comparative from the same filing: toll processing RMB 70,294,372.99, raw materials RMB 65,840.53 — toll-processing spend fell while raw-material purchases from this counterparty grew sharply).
Associate. Toll processing RMB 50,580,490.71 plus raw materials RMB 28,246,233.62. Sichuan (hydro-power graphitisation).
H1-2026 semi-annual report (filed 2026-08-28, R145 deadline pull). Toll processing RMB 39,465,607.24 plus raw materials RMB 6,951,591.81 (H1-2025 comparative from the same filing: toll processing RMB 18,679,255.31, raw materials RMB 4,173,296.34 — both roughly doubled year on year).
Associate of BTR subsidiary Jixi BTR. Raw materials RMB 2,034,820.32, down from 17,641,555.79 in FY2024. Jixi (Heilongjiang) is China's main natural flake-graphite mining district.
H1-2026 semi-annual report (filed 2026-08-28, R145 deadline pull). Raw materials RMB 1,308,582.72 — no H1-2025 comparative figure shown in this filing's related-party table (row absent from the prior-period column, consistent with this counterparty's FY2024-to-FY2025 pattern of large swings).
Controlling shareholder, 42.55% of shares and votes, Shenzhen. Ultimate parent China Baoan Group Co., Ltd. (SZSE 000009) holds 23.67% directly and 66.23% direct+indirect; it reports no controlling shareholder or actual controller of its own. Listed for ownership-graph completeness — no material goods trade with BTR is disclosed.
Scope. Absence of a counterparty here is not evidence that none exists — most commercial sourcing is confidential and never becomes public. Rows without a share figure mean no share was disclosed, not that the relationship is small.
Another tracked dossier names this company as a counterparty in its own sourced disclosure — this platform never wrote these rows on this company's own page, they are read here inverted from the dossier that disclosed them. This is a partial view: 990 additional named-counterparty rows across the corpus could not be matched to a tracked dossier by name at all (mostly non-Latin legal names), so the true count is higher than what renders here.
US CBP bills of lading via ImportGenius supplier page (retrieved 2026-09-27): BoLs CMDUCHN2780625A and CMDUCHN2780625C, arrival 2025-11-04, Oakland CA; shipper BTR NEW MATERIAL GROUP CO., LTD., consignee TESLA; ARTIFICIAL GRAPHITE SHP-A, 9,042 kg gross each; port of lading China. BTR's anode plants are in Shenzhen and other Chinese provinces; Tesla's cell lines are in the US.
Scope. This section is inverted evidence: each linked dossier wrote the original row about itself, describing its own relationship to this company. It is never a claim this company itself disclosed. Absence here is not evidence of no relationship — most of the corpus has no named-counterparty block at all yet.
This company sits on the supply side for 1 of its 5 materials — a restriction on those is a tailwind, not a headwind.
As a buyer, policy pressure across its consumed materials is rising.
Descriptive trend in official policy actions on this company’s materials — a policy-pressure trend, not a price or trading signal. No forward probability is implied. Direction is measured on actions we have discovered, and discovery lags events: where the recent window is too thin to support a calm reading, the row says coverage-limited instead of easing.
