Cornerstone Doesn’t Just Match Your Products to a Factory – We Manage Your Supply Chain from Start to Finish

Since 1991, Cornerstone has created and managed a quality-focused Asian supply chain that produces an extensive range of retail-ready consumer goods for some of the best-known companies in North America and Europe. Unlike brokers and agents who focus only on price, we’re a manufacturing partner. We manage every aspect of manufacturing your product, ensuring you receive long-lasting, high-quality goods, as you benefit from the economies of manufacturing in Asia.

Our wholly-owned Shandong office handles:

Your projects are managed by an English/Chinese speaking American, with a team of associates that have extensive experience in sourcing products in Asia. Headquartered in Dongying, Shandong Province Cornerstone manages its experienced associates in Asia to oversee the entire production process.


Our sampling process ensures the only surprises you’ll encounter are pleasant ones.

There’s nothing worse than receiving your final product after months of production, only to find the materials used don’t meet your exacting specifications. Unlike other sourcing providers, we employ a full sampling approval process to ensure your product meets your precise requirements and is fit for use before full production begins.

This sampling approval process sets us apart from others in our industry and further underscores our quality promise to deliver your product to your complete satisfaction.


We’ll provide a smooth path with no hidden fees or costs.

The key reason our customers continue to re-order from us, in many cases for decades, is because we make production easy. We cut through language and time zone barriers that typically hamper production schedules to deliver your products on time, on budget and with no surprises. And our pricing is competitive with factory-direct pricing—no hidden fees, no additional costs.
With Cornerstone offices in China, we are ideally positioned to serve our customers. From quoting a job to delivering the goods, our goal is to simplify the global-sourcing process by locating qualified factories, negotiating the lowest possible price, monitoring quality control during production and delivering the products on time.

Our production protocol includes:


On time, on spec and on budget — every time

Sourcing with just anyone to manage your supply chain can lead to serious quality issues, particularly over the life of a project. We spend significant time vetting our partners and continually audit their processes to ensure the quality you expect from the first production run is the quality you get from the 100th or even 1,000th run.

Our rigorous quality assurance process includes:


The design is in the details.

During the design phase, we work with you to determine product specifications, including size and weight dimensions, materials of construction, finishing processes, color and trim, etc. Once approved, a set of detailed production drawings is made, enabling us to focus on the types of manufacturing techniques that will be required and their costs.
The advantage of working with us is your access to a team of experts that has exhaustive experience with thousands of product design projects of every description. We know how to get it done and where to go to make it happen.
