B2B Auto Parts Export Supply Platform
Coreline Parts is a China-based B2B auto parts export supply platform. While we are currently focused on radiator plastic tanks and end tank components, our business is built to support a broader range of automotive replacement parts for wholesale buyers.
We work with established manufacturing partners in China to provide technical verification, OEM reference matching, and export coordination. We help professional buyers simplify cross-border sourcing through structured inquiry and supply support.

Who We Work With
Our platform is designed for professional buyers who need a reliable export supply partner in China. This includes auto parts wholesalers, importers, and large repair operations looking for high-quality components in bulk.
Whether you are sourcing from our current tank catalogue or looking for future expansion support, we help bridge the gap between China-based manufacturing and global B2B demand.
How We Work
We operate as a scalable supply platform. By combining technical product knowledge with export logistics, we provide a unified workflow for buyers to identify suitable products and coordinate bulk shipments.
As an independent supplier, we focus on matching the right component to the right application, ensuring specification accuracy before order, and maintaining clear communication across the export cycle.
Scalable Manufacturing Support
Coreline Parts coordinates with established manufacturing partners specialized in high-performance replacement parts. Currently focused on radiator tank production, we are expanding our network to support broader B2B needs in the automotive sector.
Tooling & Molding Experience
Our supply network includes manufacturing partners experienced in plastic tank tooling, mold-related processes, and production workflows relevant to OEM-based radiator tank supply.
OEM Reference Matching Support
We help buyers review OEM references, vehicle details, and product specifications more accurately by working with manufacturing-backed sourcing information before order confirmation.
Export-Ready Supply Coordination
From product review to shipment planning, our process is built to support structured bulk inquiries and export coordination from China to your destination.
Rather than operating as a retail reseller, Coreline Parts focuses on structured sourcing support built on real upstream manufacturing knowledge and practical export coordination for B2B buyers.
Why Buyers Work With Us
Building a B2B Parts Platform
We are building an independent export platform for high-quality automotive replacement parts. By starting with a specialized focus, we ensure technical accuracy and supply reliability for our initial categories.
While our current supply focus is on radiator plastic tanks and end tank components, we are working to expand into more selected automotive replacement parts categories based on customer demand and manufacturing capacity.
Built for Wholesale, Not Retail
Coreline Parts is structured exclusively for wholesale business. Our role is to support U.S. B2B buyers with bulk supply, product identification, and export coordination directly from China, serving as a dedicated supply partner rather than a local retail inventory seller.
This makes our service especially suitable for businesses that value sourcing clarity, product matching support, and a more direct wholesale workflow.
