Child-Resistant Cannabis Jars for US Cultivators — In Stock, DDP to Any State

American cannabis packaging is two layers, not one: a federal standard every state refers to, and a state overlay that differs wherever you look. We cannot collapse fifty rulebooks into one for you — nobody can. What we can do is supply the layer that never changes. Our glass jars and push-and-turn child-resistant closures are tested to 16 CFR 1700.20 and classified under ASTM D3475, held in stock in China, shipped in 48 working hours, and delivered DDP so the duty, clearance and freight are inside one number rather than three invoices you discover by surprise.

The layer that does not change between states

Every legal cannabis state defines child resistance by pointing at the federal Poison Prevention Packaging Act and its implementing rule at 16 CFR Part 1700. When you read enough state regulations you notice they do not write their own closure test — they borrow the federal one and then add requirements of their own on top.

Three examples we checked directly, in different regions of the country:

• Montana sets the CR standard by administrative rule at ARM 42.39.102, which states plainly that the standard is the one set by the Consumer Product Safety Commission and the testing procedure found in 16 CFR 1700.20. Its exit packages must also be opaque, and the application requires documentation that the packaging was certified by a federally qualified third-party testing firm.
• Massachusetts requires at 935 CMR 500.105(6)(a) that product containers be opaque and plain in design, avoid bright colours and cartoon features, be resealable for any product intended for more than a single use, and be certified by a qualified child-resistant packaging testing firm against the most recent version of 16 CFR 1700.
• Rhode Island has its regulator explain that whether a package is child resistant is determined by a third-party firm following 16 CFR 1700.20, that the licensee is responsible for ensuring each package is certified, and that the Office of Cannabis Regulation will not itself certify or approve any packaging as child resistant.

That last point is the one worth reading twice. In the United States nobody hands you an approval letter for your jar. Your licence carries the obligation, and the regulator asks for the paperwork when it feels like asking.

What the federal test actually asks of a closure

Child resistance under 16 CFR 1700 is a performance test, not a drawing specification, which is why "CR compliant" printed in a catalogue means nothing on its own. The protocol at 16 CFR 1700.20 is built around a panel of children aged roughly 42 to 51 months: five minutes to open the package unaided, then a demonstration, then five more minutes. To pass, a large majority must still fail after being shown how it opens — the thresholds commonly cited are at least 85 percent failing before the demonstration and at least 80 percent after — while at least 90 percent of a senior-adult panel must be able to open the package properly. A closure that defeats adults too is a failure, not a triumph, because the states also require the package to be resealable and child resistant again after opening.

Practically, this is why every CR closure on the market is a variation on two dissimilar motions — push-and-turn, squeeze-and-turn, align-the-arrows. Our stocked closures are push-and-turn in 57 mm and 60 mm.

Ask for the document that matches your combination

Here is the part suppliers hope you skip. Child resistance is a property of the jar and the closure together, not of the cap on its own. A closure that passed panel testing on one neck finish has not automatically passed on another, and the token your state regulator asks for is the test report naming the exact combination in your purchase order.

Our child-resistant jars meet 16 CFR 1700.20 and ASTM D3475. ISO 9001, CR test reports, a compliance statement and market-specific paperwork are all available — tell us which documents your team files with its regulator and we will send them. We would rather you ask for the report up front than discover the gap during an inspection.

Sizing to a one-ounce retail ceiling

Most adult-use states cap a single retail purchase of flower at around one ounce, so 28 g is where most operators stop sizing upward. The table below maps common retail fills to the jars we hold. There is no federal container limit in the United States comparable to Canada’s 30 g rule — this is a commercial ceiling set by purchase limits, not by packaging law, so check the figure that applies in your state.

Tamper evidence and exit packaging

State rules add two things that the federal CR test does not cover. First, tamper evidence: many states require a single-use feature that shows visibly whether the package has been opened before purchase. We supply shrink bands matched to each closure size. Second, exit packaging: several states, including California, Colorado, Washington, Oregon and Massachusetts, require the dispensary to place products in an opaque reclosable exit bag on the way out. Exit bags are bought separately from the jar — the jar carries the CR obligation, the bag carries the discretion one.

You can brand your jars in the United States

This is the sharpest practical difference from Canada, and it works in your favour. Canadian rules forbid brand elements outright on the immediate container. In the United States branding is permitted — what states restrict is appeal to minors, not your logo. Read 935 CMR 500.105(6)(b) in Massachusetts for the shape of it: no neon colours, no cartoons, no imitation of a non-cannabis consumer product, no celebrities or imagery used to market to minors.

What the duty line does to a quote

Glass containers of the kind we ship enter the United States under HTS 7010.90.50. The column-one general rate is zero, but Chinese-origin goods currently sit under a stack: a 25 percent Section 301 List 3 rate plus a further 12.5 percent tariff applied since 2026, which puts the practical duty load near 37.5 percent of entered value. Tariff schedules move, so confirm the current figure with your broker before you budget.

The structural point is who carries that number. On self-import you carry it, plus a customs bond, broker fees and the possibility of a bill arriving weeks after a container has already been sold. On DDP terms we are the importer of record: freight, clearance and duty are inside the landed price we quote, and what we quote is what you pay. If you sell in Canada as well, note that the same jars enter Canada duty-free under HS 7010.90.00 — details on the Canadian page.

How it travels

Cartons leave us within 48 working hours for in-stock sizes. Routing then depends on which coast you are near:

• West Coast — Los Angeles, Long Beach or Oakland, typically 14 to 18 days on the water, then truck or rail inland.
• East Coast and Gulf — Savannah, Charleston, New York or New Jersey, roughly 25 to 35 days; Houston serves Gulf accounts.
• Peak season — book before Chinese New Year and before the autumn shipping crunch. Glass has no expiry date, but a container you needed in March and receive in May is still late.
