What We Check
Quality control parameters are customized based on the product grade and downstream manufacturing requirements:
Chemical Parameters: Main compound concentration, pure nutrient content (e.g., N or K2O equivalent), and strict impurity thresholds.
Physical Parameters: Physical form (powder, crystal, or granular), particle size/mesh distribution, moisture content, anti-caking properties, and visible foreign matter.
Functional Parameters: Water solubility rate and insoluble matter limits.
Packaging & Logistics: Container integrity, bag strength, palletization/shrink-wrapping, labeling, and batch tracking.

Batch-to-Batch Consistency
For industrial chemical buyers, consistency across shipments is essential to prevent production downtime and formulation errors.
By archiving your confirmed purchasing specification (TDS) as a baseline, we apply identical inspection standards to every subsequent batch. This systemic control minimizes batch-to-batch variance for distributors, chemical importers, and raw material processing plants.
Quality Documentation & Compliance
Product Specification / Technical Data Sheet (TDS)
Defines targeted technical and physical parameters prior to production.
Certificate of Analysis (COA)
Provides actual laboratory test results for each specific batch before shipment.
Safety Data Sheet (SDS)
Contains GHS-compliant transport, storage, and handling safety data.
Traceability & Inspection Records
Tracks batch/lot identification numbers, gross/net weights, and packaging integrity.
Quality Control Process
Requirement
Buyer submits technical specification or TDS requirements.
01
Confirmation
Technical parameters are reviewed and approved by both parties.
02
Production & Inspection
Material is synthesized and tested against target specs.
03
Documentation
Batch COA and SDS are generated for review.
04
Pre-Shipment Verification
Final check on packaging, labeling, palletization, and quantity before loading.
