Hawaii Administrative Rules › Title 11 - DEPARTMENT OF HEALTH › Subtitle 1 - GENERAL DEPARTMENTAL PROVISIONS › Chapter 37 - HEMP PROCESSING AND HEMP PRODUCTS › Subchapter 2 - HEMP PRODUCT TESTING › Section 11-37-23 - Required testing for contamination and contaminant limits

Current through June, 2024
(a)
				  A representative sample of every batch of packaged and labeled hemp product
				  shall be tested for contamination by a laboratory meeting the requirements of
				  section
				  11-37-20,
				  including the use of appropriate methods to quantify the presence of all
				  contaminants listed in subsection (b).
(b) A sample and the associated batch of hemp
				  product is considered adulterated if laboratory results for the testing
				  required in subsection (a) exceed the specified concentration limit for any of
				  the following contaminants:
