How polymer deformulation, reformulation, and domestic manufacturing can reduce dependence on overseas suppliers and create a more reliable source for critical materials.
If you source a specialty adhesive, coating, sealant, or polymer component from overseas, you’ve probably had an uncomfortable conversation with your supply chain team recently. Costs and lead times have become harder to predict, and “we’ll just find another overseas supplier” isn’t as simple a solution as it once was.
Global trade conditions have become increasingly difficult to predict. Changes in tariff policy, shipping disruptions, and capacity constraints in overseas markets can affect both the cost and availability of imported raw materials and finished polymer components. For manufacturers that depend on a specific formulated material, those disruptions can create a much larger problem than a higher purchase price.
The instinctive response is usually: “Let’s find a domestic supplier.” But for most specialty polymer materials, domestic sourcing is easier said than done.
Why You Can’t Just Swap In a Domestic Alternative
The material you’re sourcing usually isn’t a generic, off-the-shelf commodity. It’s a proprietary formulation — built by someone else’s chemists, to someone else’s specification, with a mix of polymers, resins, additives, and processing steps that aren’t published anywhere. There’s no catalog listing for “the exact thing we’ve been buying,” and no domestic supplier can simply match it without knowing what’s actually in it.
Cost isn’t the only reason manufacturers start looking for a domestic alternative:
- A supplier discontinues the material. Specialty formulations can be discontinued when a formulation is sunset, a product line is dropped, or a supplier exits a market entirely, leaving customers with inventory to burn through and no clear path forward.
- Single-source dependency becomes a liability. Relying on one overseas supplier for a critical material is a well-known risk. Geopolitical tension, shipping disruptions, and regional instability can interrupt a supply chain with little warning.
- Rising import costs erode margins. When the landed cost of an imported material climbs, “absorb it or pass it on to customers” isn’t a strategy — it’s a symptom of not having a domestic alternative to fall back on.
Whatever the reason for seeking an alternative, an important question is: what, exactly, is in the material we’re currently using?
Deformulation Is the First Step Toward Independence
For many specialty polymer materials, developing a reliable domestic alternative starts with understanding the material you’re currently using. Polymer deformulation uses analytical chemistry and materials characterization to identify and quantify its major components, including base polymers, additives, fillers, stabilizers, and other formulation ingredients.
With the material characterized, polymer reformulation and development of a domestic alternative can begin. The process is made up deformulation, reformulation, scale-up, and manufacturing (production). We often refer to these steps collectively as “reverse engineering.”
- Deformulation — Characterize the existing material and identify its major components.
- Reformulation — Develop candidate formulations using available raw materials.
- Testing and Scale-Up — Evaluate performance against the original material and refine the formulation for production.
- Manufacturing — Produce the reformulated material at the required commercial volume.
The result can be more than a hedge against rising costs. A successful reformulation gives your company greater control over a critical material and reduces its dependence on overseas capacity or a single supplier.
This Isn’t a New Problem — It Just Has New Urgency
Companies have been dealing with discontinued materials, single-source suppliers, and overseas supply-chain disruptions for years. What’s changed is the level of risk involved in waiting until a problem becomes urgent. Tariffs, transportation costs, geopolitical uncertainty, and supplier consolidation can all turn a material that has been readily available for years into a significant sourcing challenge.
The broader reshoring picture is more complicated than simply bringing manufacturing back to the United States. Kearney’s 2026 Reshoring Index found that U.S. imports of manufactured goods reached a four-year high in 2025 despite record investment in domestic manufacturing. The numbers illustrate an important distinction: investing in domestic production and actually replacing established overseas supply chains aren’t the same thing.
For specialty polymer materials, that challenge can be even greater. A manufacturer can’t necessarily switch suppliers just because another company offers a product with a similar name or general application. The formulation itself may be critical to how the finished product performs — and reproducing that performance can require analytical work, formulation expertise, testing, and a path to reliable domestic manufacturing.
Deformulation and polymer reformulation can therefore be more than a response to an immediate supply-chain problem. They can be a strategy for gaining greater control over a material your business depends on — reducing reliance on a single supplier and creating a domestic source that can be developed and manufactured around your specific requirements.
Applications Across Industries
The need for a domestic formulation isn’t limited to a particular industry. Specialty adhesives, coatings, sealants, and other polymer materials are used in products ranging from electronics and medical devices to automotive, aerospace, and building materials. The specific performance requirements may differ, but the sourcing problem is similar when a critical material is available from only one supplier or one region of the world.
