A common question from wood-product manufacturers is whether wood adhesive-system development can qualify as research and development for the federal R&D tax credit under Section 41. The short answer is that wood adhesive-system development may constitute qualified research when the work evaluates alternatives to resolve a technical uncertainty about bond performance. Routine adhesive selection from established options generally is not qualified research. This page explains the framework in general terms. It is educational and is not individualized advice. For the foundational framework, see our page on qualified research.
When Adhesive-System Development May Warrant Review
Wood adhesive-system development may warrant review when the work involves a genuine technical uncertainty and a process of experimentation. Under the four-part test, the work must be for a permitted purpose, be technological in nature, be intended to eliminate uncertainty, and be conducted through a process of experimentation.
Common scenarios that may warrant review include:
- New adhesive — evaluating alternative adhesives to resolve uncertainty about whether a new adhesive can achieve the required bond strength.
- New substrate — testing alternative adhesives to resolve uncertainty about which bonds a new wood species effectively.
- New process — evaluating alternative application approaches to resolve uncertainty about whether a new process can achieve the required bond.
- Environmental resistance — testing alternative adhesive systems to resolve uncertainty about whether the bond can survive a new environment.
Routine Selection vs. Development
A central distinction is between routine adhesive selection and adhesive-system development:
- Routine selection — selecting a standard adhesive from a supplier catalog for a known application. There is no technical uncertainty. This is procurement, not research.
- Development — developing a new adhesive system where there is a technical uncertainty about whether the system can achieve the required performance. This may warrant review.
Hypothetical Example
Consider a manufacturer that is developing a new adhesive system for bonding a new wood species and is uncertain whether any available adhesive can achieve the required water-resistant bond. The company evaluates alternative adhesives, tests each for bond strength and water resistance, and systematically varies the approach to resolve the uncertainty. This may warrant review as qualified research.
By contrast, if the same manufacturer selects a standard PVA adhesive from a catalog for a known application, that is routine procurement, not research.
This example is illustrative only and does not state that the activity definitely qualifies.
Documentation That May Help
Records that can help support adhesive-system development claims include development records identifying the uncertainty and alternative adhesives, bond-strength and environmental test results, and records of how results informed adhesive decisions.

Key Takeaway
Wood adhesive-system development may constitute qualified research when the work evaluates alternatives to resolve a technical uncertainty about bond performance. Routine adhesive selection from established options generally is not qualified research. Because the distinction is fact-specific, professional review is appropriate before claiming the credit.
