Agrochemical Factory China — Pesticide Manufacturing Facility
Tour the Agrospear factory — 20,000 m² plant with compounding, grinding, filling, labeling and quality lab for agrochemical OEM/ODM manufacturing in Qingdao, China.
The Agrospear factory in Qingdao, China spans 20,000 m² with 4 specialized workshops, 200+ workers and 50,000+ tons annual output. ISO 9001, ISO 14001, BSCI and ICAMA certified. Every batch is stability-tested at 54°C for 14 days, passes a 100-point production checklist and carries 5-year material traceability. OEM/ODM production from 5-ton pilot to 20+ ton standard batches.
Specifications verified: 2026-08- As the manufacturing division of **Qingdao Vatrad Group Co., Ltd.**, Agrospear controls every stage from raw active ingredient to finished crop protection product. Our facility in the Qingdao Economic Development Zone houses dedicated workshops for compounding, grinding, filling, labeling and quality testing.
- By integrating formulation design, engineering, prototyping, manufacturing and testing under one roof, we eliminate the inefficiencies of contract manufacturing and maintain direct control over product quality, raw material selection and delivery timelines.

Production Capacity
20,000 m² facility producing 50,000+ tons/yr across formulation and packaging lines. 200+ workers, 2 shifts.
Quality Lab & Testing
Independent QC lab with HPLC, GC, particle size analyzer and stability chamber. 4 testing stages per batch.
OEM/ODM Capability
Custom formulation, private-label packaging, custom concentration grades, multi-language labeling and export-ready packing.
Workshops
Manufacturing Workshops
Compounding & High-Shear Mixing
Dedicated compounding workshop with high-shear mixers and premixing tanks. High-shear mixers blend active ingredients with dispersants, emulsifiers and carriers; sand mills produce uniform particle size distributions for SC and WDG formulations.
Formulation Grinding & Sand Milling
Sand mills and bead mills achieve target particle size distributions (D50 1–5 μm for SC, D50 20–40 μm for WDG). Spray dryers and fluid bed granulators produce WP and WDG granules.
Filling & Sealing
Automatic filling machines handle drums, jerry cans and bottles. Each batch follows a 100-point filling checklist signed off by the team lead.
Labeling & Decoration
Automatic labeling machines for multi-language GHS-compliant labels. Inkjet coders for batch and date coding with full traceability.
Equipment
Key Manufacturing Equipment
| Automatic Weighing & Dosing System | PLC-controlled, ±0.1% accuracy |
| High-Shear Mixer | 3,000–10,000 rpm, for SC/EC/SL compounding |
| Sand Mill / Bead Mill | 0.1–50 μm particle size, for SC/WDG |
| Automatic Filling Line | 20–200 L drums, 100–1000 mL bottles |
| Automatic Labeling Machine | Multi-language GHS label application |
Quality Control
Testing & Quality Assurance
Every batch undergoes mandatory testing before shipping. Our quality lab operates independently from production.
- 1
Raw Material Inspection
HPLC/GC purity analysis, impurity profiling and physical property verification before production.
- 2
14-Day Stability Test at 54°C
Every batch held at 54°C for 14 days per CIPAC MT 46. Active content deviation above ±2% triggers automatic rejection.
- 3
Active Content & Specification Verification
Completed formulations analyzed for active content by HPLC/GC and checked for suspensibility, emulsion stability, pH, viscosity and particle size.
OEM Projects
Brand & OEM Partnership Case Studies
From concept to production — how we help global brands launch and scale agrochemical product lines.
- Challenge
- European agrochemical distributor needed a private-label herbicide range with unique formulations and REACH-compliant ingredients delivered in 60 days.
- Solution
- Developed custom SC formulations, sourced REACH-compliant actives and compressed sampling by co-locating the formulation team at our factory.
- Result
- 25–35 days production from signed PO. 200+ tons across 4 SKUs. Repeat order placed before first batch was fully delivered.
- Challenge
- US crop protection startup needed a high-efficacy insecticide SC formulation with custom concentration and ICAMA registration.
- Solution
- Adapted existing SC formulation with modified AI ratio, developed co-branded packaging and provided full ICAMA registration documentation.
- Result
- Over 500 tons sold in Year 1 with a 95% reorder rate.
FAQ
Factory — Frequently Asked Questions
What is the MOQ for OEM agrochemical formulations?+
MOQ is confirmed by project configuration. Standard volume production runs 20+ tons per batch, pilot runs start at 5 tons and every project moves through sample (1–4 tons) and pilot stages.
What certifications does the factory hold?+
ISO 9001, ISO 14001, BSCI and ICAMA. Full compliance documentation is provided with every OEM shipment.
What is the typical lead time?+
Standard lead time is 25–35 days from confirmed PO and deposit. Custom formulation development adds 15–20 days. Prototype samples typically ready in 7–14 days.
Do you handle export documentation?+
Yes. We manage export documentation and customs clearance in-house, supplying to 50+ countries.
