Source FRP from China — products, standards, one accountable desk
The whole China FRP supply base, audited and mapped. See what you can source, how Chinese GB standards map to ASTM / ISO / EN, and the step-by-step path — then hand the factory-side work to one bilingual desk that sources as your principal.
- What FRP products to source (profiles, grating, rebar, pipe) and the audited supply base behind them — by capability and scale tier
- Province-by-province map of where each FRP product category is actually made (resin = Jiangsu, fiber = Shandong, etc.)
- GB ⇄ ASTM ⇄ ISO ⇄ EN standards crosswalk — set spec expectations before the RFQ, not after
- A 6-step sourcing playbook from spec to delivered cargo, with payment / QC / Incoterms benchmarks
FRP product families we source from China
Figures are schematic. Tell us the spec and target standard — we match the right plant from the audited network and stand behind delivery.
The audited network, by capability and scale
The supply base behind those products, shown in aggregate. Each card is a supply-chain role with its audited plant count and scale mix — Major (listed groups / Tier-1) through Small (niche SMEs). We pick and stand behind the specific plant for your spec; you deal with one desk, not a directory.
Where Chinese FRP capacity actually lives
Chinese composites capacity is regionally clustered. Jiangsu does resin, Shandong does fiber, Zhejiang does mid-volume manufacturing, Henan and Shanxi cover basalt. Knowing which province handles your slice of the value chain saves weeks of RFQ blast and weeds out three-quarters of the no-fit responses upfront.
Pultrusion, gratings, profiles
Resins, gelcoats, auxiliaries
Tanks, pipes, wind blade fabrics
CFRP parts, autoclave, trade
Pipes, tanks, industrial FRP
Carbon fiber production
Glass fiber (Taishan Fiberglass)
Trade houses, QC labs, certification
Marine FRP, ship-yard composites
Boats, recreational composites
Certifications that actually unlock cross-border purchase orders
A certification only matters when your end-market requires it. This decodes the ones overseas buyers screen by, and shows how many suppliers on the platform currently hold each one.
Minimum baseline required by most Tier-1 OEMs for supplier onboarding.
Require in your RFQ →Mandatory for EU customers governed by ESG / supply-chain-due-diligence rules.
Require in your RFQ →Increasingly expected by automotive and energy buyers.
Required for construction products (CPR), machinery, PPE when sold in the EU / EEA.
Require in your RFQ →Required for FRP pressure vessels and process piping sold into the US market.
Require in your RFQ →API-15HR / 15LR / 15S certify FRP pipe for oilfield and petrochemical duty.
Require in your RFQ →Required for FRP vessels, piping, gratings used in ships and offshore platforms.
Require in your RFQ →Required for any CFRP structure entering aerospace and defense supply chains.
Require in your RFQ →Mandatory for Tier-1 / Tier-2 automotive CFRP and SMC structural suppliers.
Require in your RFQ →UL-94 flame rating is required for FRP used in electrical enclosures and cable trays.
Require in your RFQ →GB ⇄ ASTM / ISO / EN for composite test methods and products
If your supplier tests per GB, does that satisfy your ASTM-based spec? Short answer: often structurally similar, sometimes geometrically different. Use this table to set expectations before the RFQ, not after.

From spec to delivered cargo: the 6-step path
A condensed operational guide if this is your first time buying FRP from China. Each step links to the tool on this site that does the heavy lifting for it.
Before talking to any supplier, write a one-page spec: product, grade, geometry, key property targets (tensile / flexural / HDT), applicable standard, and end-use environment.
Tool: /materials to benchmark property ranges
Filter by province (capability cluster), by process capability, and by certifications that match your market. Aim for 3–5 — more creates RFQ overhead without improving price discovery.
Tool: the vetted network + RFQ
Send identical RFQ packets with the spec, target volume (3-month & 12-month), Incoterms (FOB / CIF / DAP), required documentation (MTC, test reports), and target price range.
Tool: AI-assisted RFQ drafting at /ai
Request 3–5 pieces for independent third-party testing (SGS / Bureau Veritas / TÜV labs in China). Never skip this for structural or safety-critical parts. Cost: typically USD 500–2,000 per test panel.
Tool: standards database for test-method selection
Standard terms: 30% deposit against PI, 70% on B/L copy. First-time orders should use LC at sight for > USD 50k. Always name the exact certifications, batch traceability, and packaging spec in the contract.
Reference: Incoterms 2020, ICC Publication 723E
Pre-shipment inspection (PSI) at factory — random sampling per AQL. MTC, CoC, and packing list must match the PO. For FRP, verify cure state and visual defect class per ASTM D4385 or EN 13706.
QC vendors: SGS, Intertek, Bureau Veritas, TÜV Rheinland China
