What Is ASTM Certification for Cannabis Packaging — And Why Should Dispensaries Care?
If you’ve shopped for child-resistant cannabis packaging, you’ve seen “ASTM certified” listed as a product feature. Most suppliers mention it. Far fewer explain what it actually means — or why it matters when you’re making a purchasing decision for a licensed cannabis operation.
This is the explainer.
What ASTM Is
ASTM International (formerly the American Society for Testing and Materials) is a nonprofit organization that develops and publishes technical standards for a wide range of industries — materials, products, systems, and services. They’re not a government body, but their standards are widely adopted by regulators as the benchmark for product performance.
In cannabis packaging, two ASTM standards are most relevant:
ASTM D3475 — the primary standard for child-resistant packaging. It defines testing protocols and performance requirements for CR closures on packaging intended for household products that could harm children.
ASTM D4169 — covers performance testing for shipping containers and systems, sometimes referenced for cannabis transit packaging.
When a cannabis packaging supplier says their bags are “ASTM D3475 certified,” it means the closure mechanism on those bags has been tested by a third-party laboratory and verified to meet specific performance thresholds.
What the Testing Actually Measures
The ASTM D3475 standard sets two simultaneous requirements:
Child panel: At least 85% of children in the test group (ages 42–51 months — the window where hand strength and dexterity are most developed) must fail to open the package within a set timeframe, even after being shown how it’s done.
Adult panel: At least 90% of adults must be able to open and reseal the package without assistance.
Both thresholds must be met for certification. A package that’s impossible for children to open but also impossible for adults to use isn’t compliant — and neither is one that adults can open easily but children can too.
This dual requirement is what separates genuinely certified CR packaging from bags that are merely described as “child-resistant” without documentation.
Why This Matters for Your Dispensary License
Here’s where the distinction becomes operationally important.
Every U.S. state with a legal cannabis program requires child-resistant packaging for most cannabis products. But when states write their packaging regulations, they don’t just say “use a child-resistant bag.” They reference performance standards — and the standard they most commonly cite is ASTM D3475, or its federal equivalent under CPSC guidelines (16 CFR 1700.15/1700.20).
This means two things for dispensary operators:
1. “Child-resistant” as a marketing claim isn’t enough. A bag can have a zipper and a supplier can call it child-resistant. If that closure hasn’t been tested to ASTM D3475 standards, it doesn’t satisfy the regulatory requirement — regardless of what the product listing says. If an inspector asks for certification documentation and you can’t provide it, you have a problem.
2. You may need to produce documentation. Some states, retail partners, and MSO procurement teams require suppliers to provide written certification documentation before approving packaging. If your supplier can’t provide a test report, you can’t verify compliance — and you absorb that risk.
This is why we offer certified packaging with documentation available on request. It’s not a premium feature. It’s what legitimate compliance looks like.
Pinch & Pull vs. Lock N Pull: Both Certified, Different Applications
Within certified CR packaging, there’s still meaningful variation in how the closure works — and that matters in some regulatory environments.
Pinch & Pull closures use a zipper that requires simultaneous pinching of both sides before the bag can be opened. The mechanism satisfies ASTM D3475 and meets child-resistant requirements in most legal cannabis states. It’s the most widely used CR format in the industry, consumers recognize it, and it balances compliance with ease of use for adults.
Lock N Pull closures add a locking step. Before the zipper can be engaged, a secondary mechanism must be released — requiring a two-step process that provides stronger child resistance. Lock N Pull is the preferred format in states with elevated packaging requirements, for medical cannabis programs where the patient population may include more vulnerable individuals, and for operators who want the most defensible compliance documentation available.
Both our Custom Pinch & Pull Bag and Custom Lock N Pull Bag are ASTM-certified. Which one is right for you depends on your state and your compliance posture. If you’re unsure, contact us — we’ll review your state’s requirements and give you a straight answer.
What to Ask Your Packaging Supplier
When sourcing CR packaging for your cannabis operation, these are the questions that separate certified suppliers from marketing claims:
1. Is this packaging certified to ASTM D3475?
If the answer is yes, ask for the test report. A legitimate certification has documentation behind it.
2. Was testing conducted by a third-party lab?
Self-certification isn’t the same as independent testing. ASTM D3475 compliance requires testing by an accredited laboratory.
3. Can you provide documentation for our compliance records?
If the answer is no or evasive, that’s a red flag. Any serious compliance-oriented supplier should be able to provide paperwork.
4. Does the certification cover the specific size I’m ordering?
Certifications are specific to a closure mechanism, not always to every size variant. If you’re ordering a large-format bag, confirm the certification applies to that size.
A Note on State Variation
One thing that trips operators up: state regulations don’t all reference ASTM D3475 by name. Some states reference CPSC standards (16 CFR 1700.15 and 1700.20), which have similar but not identical requirements. Most ASTM D3475-certified packaging also satisfies CPSC standards, but the two aren’t identical, and some states are more specific than others.
This is why we always recommend verifying against your state’s current regulatory text — not a guide like this one — before placing a packaging order. Our state compliance guides are a useful starting reference, but regulations change and the official source is always the state regulatory agency.
Bottom Line
ASTM certification is the documented proof that your child-resistant packaging has been independently tested and verified — not just described as CR in a product listing. For licensed cannabis operators, it’s the difference between packaging that satisfies a compliance audit and packaging that only looks like it will.
If you’re currently using packaging that doesn’t have third-party certification documentation behind it, it’s worth a conversation with your supplier before your next state inspection.
