Labeling of Hazardous Art Materials Act (LHAMA) Evaluation

Product safety is a primary concern for the arts and crafts industry.  Intrinsik’s team of experienced toxicology and regulatory professionals assist with the assessment of arts materials and deliver high quality evaluations to ensure the safe use of products.

The Labeling of Hazardous Art Materials Act (LHAMA) and ASTM D-4236 requires that all art materials marketed in the United States undergo a toxicological review to determine the product’s potential for producing adverse chronic health effects and hazard labeling.

Art materials also require Toxicological Risk Assessment (TRA) evaluations and must be properly labeled for acute hazards as required by Consumer Product Safety Commission (CPSC) and the Federal Hazardous Substances Act (FHSA).


  • Evaluation of the toxicity profiles of the chemicals in the product
    • Toxicology endpoints include chronic toxicity, corrosion or damage to the skin and eye), sensitization (dermal and respiratory), mutagenicity, carcinogenicity, and reproductive and developmental toxicity
  • Exposure considerations (e.g., physical characteristics, accessibility and intended use of the product)
  • Consideration of foreseeable misuse of the product
  • Recommendations for product label warnings (as necessary)
  • ASTM D-4236 (LHAMA certification)

All of our LHAMA evaluations are approved by a Board-Certified Toxicologist.
