Croatia Amends RoHS Lead Exemptions and Bans Misuse of Nitrous Oxide
In May 2026 Croatia published NN 49/2026, amending its RoHS ordinance to align lead exemptions with new EU deadlines and introducing a national order banning misuse of nitrous oxide in products, with application from June–July 2026. EEE manufacturers and importers must plan for tighter lead-use sunset dates while distributors and users of N₂O-containing products face stronger controls and enforcement risk around uses outside manufacturers’ intended purposes.
CroatiaCalifornia AB 2776: Hazardous Materials Storage Tank and Gas Reporting Bill Moves to Senate
California’s AB 2776, which tightens rules on hazardous waste treatment, petroleum storage tanks, leak detection and hazardous gas reporting thresholds, has passed the Assembly and received its first reading in the Senate on 7 May 2026. If enacted, it would narrow exemptions for certain storage tanks, require faster corrective action and new leak-detection standards, and raise business-plan thresholds for specified industrial and medical gases, increasing compliance expectations for California facilities handling hazardous materials.
United StatesNew Hampshire Senate Adopts Ought-To-Pass Motion On HB 1630 Nitrous Oxide Sale Ban
In May 2026 the New Hampshire Senate advanced HB 1630, a bill to ban most retail nitrous oxide devices for recreational use and tighten inhalant controls on liquor-licensed premises, with a planned effective date of January 2027 if enacted. If the bill becomes law, retailers and hospitality operators holding liquor licences in New Hampshire will need to remove affected products, revise compliance programmes, and monitor further rulemaking and enforcement by the liquor commission.
United StatesCalifornia Assembly Appropriations Committee Advances Hazardous Materials Bill AB 2776 to Consent Calendar
In late April 2026, California’s hazardous materials bill AB 2776 cleared Assembly Appropriations on a unanimous vote and was moved onto the Assembly Consent Calendar for floor consideration. If enacted, the bill would tighten hazardous waste and petroleum storage tank controls and raise hazardous gas reporting obligations, so operators using these systems in California should monitor the remaining votes and prepare for possible compliance changes.
United StatesCalifornia Assembly Committee Advances AB 2776 Hazardous Materials Storage Tank Bill to Appropriations
In April 2026, a California Assembly committee unanimously advanced AB 2776, a bill tightening hazardous waste treatment rules, petroleum storage tank requirements, and hazardous gas business-plan thresholds, and sent it to the Appropriations Committee with a consent-calendar recommendation. If enacted, the measure would broaden which California facilities must upgrade tank containment and leak detection, adjust emergency notification triggers for petroleum releases, and expand hazardous gas reporting and emergency planning obligations for sites using medical and industrial gases.
United StatesWashington Enacts HB 2532 on Nitrous Oxide Sale and Distribution
Washington has enacted HB 2532, creating a new gross-misdemeanor offence that prohibits selling or supplying nitrous oxide canisters and similar devices except for limited professional and industrial uses from 11 June 2026. Businesses that manufacture, distribute, or use nitrous oxide must now restrict consumer-facing sales, confirm that remaining transactions fall within exempt medical, food-grade, industrial, or automotive channels, and prepare for enforcement of the new offence.
United StatesIndiana Enacts SB0185 (Public Law 148) on Tobacco, E-Liquid and Nitrous Oxide Controls
In March 2026, Indiana enacted Public Law 148 (SB0185), overhauling state rules for tobacco, e-liquids, vapor devices, cigarette pricing and flavoured nitrous oxide, with most provisions taking effect from 1 July 2026. This creates materially tighter licensing, sourcing, reporting and enforcement expectations for manufacturers, wholesalers and retailers of tobacco and vaping products, especially where supply chains touch foreign adversary jurisdictions or rely on non-FDA-supported e-liquid formulations.
United StatesEU Commission Proposes REACH Annex XVII CMR List Update and Nitrous Oxide/Lead Derogations
In April 2026 the European Commission sent a draft Commission Regulation to the REACH Committee to update Annex XVII CMR restrictions, adding newly classified carcinogenic, mutagenic and reprotoxic substances and creating targeted derogations for lead fishing sinkers and nitrous oxide uses. If adopted, this will tighten EU general-public restrictions on a broad set of CMR chemicals and reshape the rules for nitrous oxide cartridges and lead fishing tackle, requiring manufacturers and distributors to reassess consumer-facing formulations, supply chains, and 2027 transition plans.
European UnionCalifornia Assembly Adopts Amendments to Hazardous Materials Bill AB 2776 at Second Reading
On 26 March 2026 the California Assembly read hazardous materials bill AB 2776 a second time, adopted authors’ amendments, and re-referred it to the Environmental Safety and Toxic Materials Committee. This keeps a broad revision of hazardous waste, petroleum storage and hazardous materials business plan rules moving through the legislature, so California operators handling hazardous materials should monitor the amended text and committee actions for potential changes to storage, reporting and emergency planning obligations.
United StatesNew York Assembly Proposes Statewide Ban on Retail Sale of Nitrous Oxide
New York has introduced Assembly Bill A10923 to create a statewide ban on retail nitrous oxide sales, tighten oversight of non-retail uses, and expand public health education on nitrous oxide misuse. If enacted, retailers and distributors would need to cease consumer nitrous oxide sales, ensure any remaining supply is covered by Department of Health exemptions, and prepare for a uniform state regime that pre-empts existing local ordinances.
United StatesCalifornia SB 1314 Proposes 600-Foot Smoke Shop Buffers and Nitrous Oxide Ban
California’s SB 1314 would create a new statewide regime for smoke shops, imposing 600-foot buffer zones around schools and day care centres, restricting operating hours, and banning nitrous oxide products and paraphernalia from these premises from July 2027. If enacted, the bill would significantly tighten youth-access and product controls under California’s tobacco enforcement and licensing framework, forcing smoke shop operators and their suppliers to reassess locations, product assortments, and compliance systems well ahead of the 2027 start date.
United StatesMinnesota Senate Committee Holds Oversight Hearing on Nitrogen, Nitrates, and Nitrous Oxide Regulatory Actions
Minnesota is intensifying oversight of nitrogen and nitrate regulations to address groundwater contamination and meet updated nutrient reduction targets. Industrial and agricultural operators face increased risk of stricter discharge permits and mandatory nutrient management protocols as state agencies align with the 2025 Nutrient Reduction Strategy.
United StatesNetherlands Court of Appeal Confirms Nitrous Oxide Conviction Without Chemical Test
The Dutch Court of Appeal has ruled that illegal nitrous oxide trade can be prosecuted using labeling and circumstantial evidence rather than mandatory laboratory testing. This precedent simplifies enforcement procedures and increases the risk of criminal liability for entities involved in the distribution of controlled substances.
NetherlandsMassachusetts House Committee Refers Nitrous Oxide Sales Bill H5273 to Ways and Means
Massachusetts is advancing legislation to restrict the sale of nitrous oxide, with Bill H5273 recently moving to the House Ways and Means Committee. Businesses should anticipate new compliance obligations and potential market access restrictions for nitrous oxide products as the state tightens controls on substance distribution.
United StatesMinnesota Senate Introduces Greenhouse Gas Pollution Superfund Act (SF 4886)
Minnesota introduced the Greenhouse Gas Pollution Superfund Act to impose strict liability on major fossil fuel producers for historic greenhouse gas emissions. This polluter-pays model creates significant financial exposure for large energy companies and signals a shift toward state-level recovery of climate adaptation costs.
United StatesNew York Senate Bill S9567 Proposes Ban on Retail Sale of Nitrous Oxide
New York has proposed a total ban on the retail sale of nitrous oxide to the general public, targeting consumer products like whipped cream chargers. Affected businesses face a complete loss of consumer market access and must prepare for a shift toward strictly controlled professional distribution channels.
United StatesCalifornia Bill AB 2447 (Water Supply Protection Act) Would Tighten Agricultural Nitrogen Discharge Controls
California is advancing legislation to mandate strict quantitative limits on nitrogen fertilizer application and discharge for irrigated agriculture starting in 2028. Fertilizer producers and agricultural operators face significant compliance shifts through mandatory field-level reporting, public data transparency, and new technology-based performance standards.
United StatesNorway: Landbruksdirektoratet and Miljødirektoratet Publish Plan for Sustainable Nitrogen Use in Agriculture
Norway has released a strategic roadmap to reduce nitrogen losses in agriculture by targeting ammonia emissions, nitrous oxide, and water runoff. This plan signals future regulatory tightening for fertilizer management, manure storage, and the development of recycled nutrient standards.
NorwayUS Congress Introduces H.R. 7945 To Ban Sale of Nitrous Oxide Consumer Products
US House Bill H.R. 7945 was introduced in March 2026 to establish a federal ban on the sale of nitrous oxide consumer products. Impacted companies should prepare for significant market access restrictions and monitor the forthcoming bill text for critical definitions and exemptions.
United StatesEU Parliament Debates Commission Statement on Ban on Sale of Nitrous Oxide to the General Public
The European Parliament has initiated discussions on a potential EU-wide ban on nitrous oxide sales to the general public.
