The Coastline Difference
In addition to our high-level contract manufacturing solutions, our team can also manage the procurement and logistics processes for you, including the full “turnkey” solution of procurement of materials and components, materials management, alternate source suggestions, and import/export management.
Our typical client develops their products in the United States, outsources some or all of their manufacturing to our Mexico facility, and markets & sells their products in domestic and international markets, reducing costs and creating a viable manufacturing solution.
Per ISO standards, Coastline can perform quality assurance testing and first article inspection to ensure that every finished good meets your exact business specifications before being shipped from our manufacturing facility to its destination.
What is contract manufacturing?
Contract manufacturing is when an OEM (original equipment manufacturer) partners with a third-party manufacturer — often called a CMO, or contract manufacturing organization — to produce some or all of a product on their behalf. The contract manufacturer builds to the OEM’s exact specifications and quality standards, so the finished product is effectively identical to one produced in-house. This allows OEMs to reduce costs, free up internal resources, and focus on core activities like product design and development.
Why manufacture in Tijuana, Mexico instead of Asia?
Tijuana offers the advantages of nearshore manufacturing that overseas locations can’t match: it sits just 15 minutes from the San Diego border, in a similar time zone to U.S. operations, allowing for real-time communication and easier site visits. Products manufactured in Mexico also qualify for USMCA trade preference, reducing duties compared to sourcing from Asia. Combined with shorter shipping distances, this typically means faster delivery to U.S. markets and lower total landed cost.
What industries does Coastline serve?
Coastline provides contract manufacturing for the medical device, electronics, aerospace, and consumer product industries. Our medical device work spans Class I, II, and III products, including disposables, surgical devices, and electronic medical devices. On the electronics side, we manufacture consumer and industrial electronics and subassemblies, including custom battery packs, cable harnesses, power supplies, and box builds.
Is Coastline ISO and FDA certified?
Yes. All Coastline manufacturing operations are ISO 13485 and ISO 9001 certified, and our facilities are FDA registered. These certifications reflect our quality management systems for both general manufacturing and medical device production, and they’re a core reason OEMs in regulated industries trust Coastline with their products.
What is a shelter manufacturing company, and does Coastline offer shelter services?
A shelter company (or IMMEX shelter services) allows a foreign OEM to manufacture in Mexico without establishing its own legal entity there — the shelter company handles the legal, HR, tax, customs, and compliance requirements on the OEM’s behalf. Coastline offers shelter services as part of our turnkey solutions, giving companies the option to manage their own production in our facilities while we handle the administrative and regulatory complexity of operating in Mexico.
What is the minimum order size? Does Coastline work with startups, or only large OEMs?
Coastline works with companies of all sizes, from startups bringing a first product to market to established OEMs transferring high-volume production lines. Rather than a fixed minimum order size, we evaluate each project individually based on product complexity, timeline, and long-term production needs. Reach out to discuss your specific volume and we can advise on the best path forward.
How does USMCA affect contract manufacturing costs in Mexico?
USMCA (formerly NAFTA) allows qualifying products manufactured in Mexico to move across the U.S. border with reduced or eliminated tariffs, lowering total landed cost compared to manufacturing in non-trade-agreement countries. Combined with Mexico’s lower labor costs and Coastline’s proximity to the San Diego border, this makes Tijuana manufacturing a cost-effective alternative to both U.S. domestic production and overseas manufacturing. Our team can help you understand how USMCA rules of origin apply to your specific product.
