HB 1780 New Hampshire House · 2026 Regular Session

relative to seed laws.

This bill increases penalties for businesses repeatedly violating laws governing the sale of seeds, plants, and nursery stock in New Hampshire. It establishes a three-tier penalty system for "habitual offenders": a six-month sales ban at the violation location for a second offense, a one-year ban for a third offense, and permanent prohibition for a fourth violation. The Department of Agriculture will define "habitual violation" through rules, and penalties apply specifically to the business location where violations occur. These changes take effect January 1, 2027, directly affecting sellers of agricultural products who face repeated enforcement actions.

MODERATE
The Senate significantly expanded HB 1780 from a narrow bill prohibiting the sale of seed more than 36 months after production into a broader seed law package. It adds a formal definition of 'production date,' requires that date to appear on seed labels, creates new rules about how relabeling stickers must handle the original production date, and restructures the prohibitions into separate paragraphs. The Senate also restored the one-time relabeling limit that the House had removed.
DEFINITION

Added a new definition of 'production date' in RSA 433:1, meaning the calendar month and year that a seed lot's first germination test was completed.

REQUIREMENT

Added a new labeling requirement in RSA 433:2, III(i) requiring the production date to appear on labels for agricultural, vegetable, and flower seeds.

Added a new prohibition (paragraph h) requiring that any relabeling sticker either not cover the original production date or carry forward the original production date.

The 36-month sale prohibition was separated from the relabeling rules into its own standalone paragraph (i), making it a distinct violation rather than part of the relabeling provision.

Restored the language 'Relabeling shall not occur more than once' which the House version had placed in brackets (indicating removal). The Senate kept this restriction active.

SCOPE

The bill title changed from 'prohibiting the sale of seed more than 36 months after the production date' to 'relative to seed laws,' reflecting a much broader scope covering definitions, labeling, relabeling rules, and multiple prohibitions.

TECHNICAL

The prohibition on altering or falsifying seed labels, tests, reports, records, or documents was moved from paragraph (h) to a new paragraph (j), and the cross-reference to RSA 433:2, III(g) in the old paragraph (g) was removed.
