HI SB637

Allows hemp processors to register and operate in agricultural buildings exempt from building permits and codes (buildings under 1,000 square feet such as shipping containers or wood-framed structures) as long as processing does not involve heat or volatile compounds or gases under pressure.

Permits hemp processing operations to be conducted in food hubs as described in section 205-2 or agricultural parks as alternative locations to fully code-compliant facilities.

Requires hemp processor applicants to provide documentation with registration applications showing their operation either complies with zoning, building, and fire codes OR qualifies for an exemption under section 46-88 OR is located in a food hub or agricultural park.

Clarifies that documentation requirements for hemp processor registration must be obtained from the United States Department of Agriculture rather than only the Secretary of Agriculture.

Addresses Hawaii's hemp industry overregulation that has stifled growth and driven farmers out of business by reducing expensive tolling fees for processing hemp.
