Specialized Supply Chain & Polymer Expertise
Dongguan Zhonghui International Trading Co., Ltd. is located in Zhangmutou Town, Dongguan City, Guangdong Province, China. For decades, Zhangmutou has been recognized as South China's most significant raw polymer and engineering plastics trading hub, hosting thousands of resin distributors, compounding lines, and testing facilities.
Having built extensive domestic experience and supply partnerships in China's plastic manufacturing ecosystem—including our established 1688 commercial presence—we are actively developing international sales channels dedicated strictly to two fundamental masterbatch categories:
Black Masterbatch
High-jetness, high-dispersion carbon black formulations on virgin PE/PP carriers for film, pipes, injection, and recycled polymer masking.
White Masterbatch
High-opacity rutile titanium dioxide formulations for packaging film, bottles, thermoformed sheets, and food-grade containers.
Our core value lies in deep technical understanding of polymer processing, direct sourcing integration, strict lot-to-lot verification, and practical support that helps international factories lower let-down ratios without risking extrusion stability.

Why Zhangmutou, Dongguan Matters for Your Supply
Being positioned directly within China's largest polymer marketplace provides international buyers with distinct competitive advantages.
Raw Polymer Sourcing Agility
Immediate proximity to primary resin importers and petrochemical producers gives us continuous access to virgin LDPE, LLDPE, HDPE, and PP carriers, insulating our compounding from carrier shortages.
1–2 Hours to Major Ocean Terminals
Zhangmutou is located within 60–90 km of Shenzhen Port (Yantian, Shekou) and Guangzhou Port (Nansha). This drastically reduces inland trucking lead times and drayage expenses for 20ft and 40ft container exports.
Rigorous Lot Testing & Verification
We inspect every incoming batch for melt flow index (MFI), moisture percentage, dispersion consistency, and ash content before palletizing for export, ensuring consistent performance on your machines.
Serving Southeast Asia & Africa
Our international market strategy is directed towards manufacturing economies in Southeast Asia and Africa where plastic processing—such as shopping bag blowing, agricultural films, beverage caps, and drainage pipes—is expanding rapidly.
We are actively seeking long-term relationships with plastic factories, polymer compounders, and regional industrial raw-material distributors in:
Vietnam, Indonesia, Thailand, Malaysia, Philippines, Bangladesh, Pakistan.
Kenya, Tanzania, Uganda, Nigeria, Ghana, and neighboring industrial centers.
Export Logistics Standards
- Packaging: 25 kg moisture-proof multi-ply craft paper / PE valve bags.
- Palletization: 1,000 kg – 1,250 kg per fumigated wooden / plastic pallet, stretch-wrapped.
- Container Loading: 20–22 MT per 20GP container (with or without pallets).
- Documentation: COA, Commercial Invoice, Packing List, BL, Certificate of Origin (Form E, etc.).
