Engineered for absolute regulatory compliance and premium brand presence. Explore our primary certified structures below.
CR Tin (Andylots Tin Box Packaging Co.,Ltd) is a streamlined, single-source professional supplier of child resistant tin boxes, integrating child resistant lock design, mold making and sampling, child resistant lock testing, and mass production. CR Tin began developing child resistant lock tin boxes in 2017. After nine years of research and development and pioneering experience, we have over 70 certified child resistant lock tin boxes, covering all tin box packaging styles in the industry, and have established our own unique child resistant lock tin box system.
Our commitment to structural excellence and child safety has made us a trusted manufacturing partner for major multi-state operators (MSOs) and global brands. We don't just supply metal packaging; we design bespoke, compliant safety architectures that elevate consumer confidence and protect brand integrity in highly regulated markets.
Why regulatory alignment is the foundation of high-performance cannabis and pharmaceutical packaging.
The manufacturing of packaging for edibles, especially active cannabinoid products, requires an uncompromising approach to consumer safety and federal regulations. Under guidelines like the United States Poison Prevention Packaging Act (PPPA) and standards designated under 16 CFR § 1700.20, child-resistant (CR) packaging must restrict access to children under 5 years old while remaining simple enough for seniors to open. CR Tin engineers have systematically designed metal locking structures that align directly with these stringent parameters, reducing liability for brands and enhancing public health protection.
Our tins are designed according to the testing frameworks of ASTM D3475 (Standard Classification of Child-Resistant Packages). Standard testing protocols require that packages undergo rigorous testing panels: 200 children aged 42-51 months must be unable to open the package within 10 minutes, while 100 seniors aged 50-70 must successfully open it. The engineering must survive repeated openings throughout the lifetime of the product, particularly for multi-serving packages like gummies or chocolates. Metal offers a unique engineering advantage here—it maintains structural integrity without degrading, unlike plastic mechanisms which suffer from fatigue.
Classified structures tested meticulously for child-resistant compliance, ensuring legal security for your brand across major legal global markets.
Utilizing high-purity electrolytic tinplate (ETP) coated with FDA-approved, BPA-free, and REACH-compliant food-contact varnishes.
Rigid metal construction guarantees the locking mechanism maintains compliance and functionality from the first dose to the very last.
How our integrated design-to-production capability minimizes time-to-market while reducing overhead costs.
We provide over 12 distinct certified child-resistant tin structures as standard options. This diverse architectural baseline ensures that whether you require hinged tins, sliding mechanisms, round push-and-turn canisters, or clamshell designs, we have an existing verified structure ready for customization. By choosing an established structure, brands bypass the high cost and long development times of custom certification testing.
Our dedicated design team provides free unique CR tin design and creative services. Armed with advanced CAD modeling software, 3D rendering, and 3D printing equipment, we turn raw concepts into physical mockups rapidly. This allows physical mechanical testing of the lock before committing capital to tooling development.
We operate advanced automation systems across 8+ lines to ensure stable, repeatable manufacturing metrics. Hand-operated lines create variances that can compromise locking safety; automation eliminates human error. Every accessory, spring steel piece, and hinge aligns perfectly to maintain regulatory standards.
Providing compliant child-resistant packaging does not require prohibitive costs. Through decades of supply chain mastery, automated scaling, and structural refinement, we maintain highly competitive pricing models. We reduce overhead costs at every stage of the tin fabrication process:
Navigating complex state-by-state and national policies to keep your brand on the shelves.
Regional legal requirements represent a major challenge for cannabis MSOs and dietary supplement brands. In the United States, states like California, Colorado, Oregon, and Washington have distinct, evolving packaging guidelines. For instance, packages must be child-resistant, opaque or semi-opaque, and resealable if they contain multiple servings. In Canada, Health Canada enforces uniform warning labels, standardized THC symbols, and highly regulated background graphics. In Europe and Australia, pharmaceutical-grade child resistance standards are required for medicinal preparations.
CR Tin provides comprehensive local compliance assistance. We provide physical certification documentation and test data sheets for all certified tins. This helps expedite the validation process with state inspectors and distribution networks. Furthermore, our design team helps integrate state-mandated warning labels, QR codes for laboratory certificate of analysis (COA) compliance, and mandatory warning text directly into the tin's lithographic artwork.
Full support for Health Canada and US state laws, ensuring compliant packaging formats for active compounds, including state-specific labeling integration.
Designed to meet ISO 8317 requirements for child-resistant reclosable packaging. Fully compliant with REACH chemical safety regulations.
We print QR codes, serial numbers, and variable tracking data directly onto tins to support local seed-to-sale tracking systems.
How our domestic manufacturing cluster drives efficiency, reliability, and fast turnaround cycles.
Located in the heart of China's premier industrial manufacturing zone, CR Tin leverages robust regional supply chains. This localized network includes top-tier raw steel suppliers, precision lithography printing houses, and expert tooling engineers. This concentration of resources enables rapid prototyping, cost efficiency, and supply chain security that Western competitors struggle to match.
By using local, automated raw material processing and nearby deep-water shipping hubs, we reduce domestic transit times. This helps us ship finished tins to North America, Europe, and Asia efficiently. Our strong relationships with local shipping providers ensure competitive freight rates, customs clearance support, and reliable logistics, even during peak seasons.
Tailoring container specifications to the physical properties of modern consumer edibles.
Gummies require strict environmental controls to prevent melting and moisture absorption. We integrate food-grade silicone liners and airtight seals that prevent moisture and air exchange, extending shelf life and preventing product stickiness.
Chocolates require rigid packaging to prevent breaking during shipping, as well as a clean flavor profile. Our food-safe, odor-free varnishes preserve flavor profiles, while our sturdy metal structures protect delicate products from pressure and impact.
To preserve essential oils and terpenes, our airtight metal cases prevent odors from escaping and moisture from entering. This ensures products remain fresh and discreet during transport.
Three key trends shape the child-resistant metal packaging landscape today:
Ensuring safety, consistency, and compliance at every step of production.
CR Tin provides a diverse selection of ASTM-certified child-resistant metal packaging. Over our years of production, we have created a standardized series of child-resistant tin boxes. These options provide brands with reliable, cost-effective packaging that satisfies strict child safety regulations.
We implement a strict quality control system to ensure every shipment complies with child safety laws. From sourcing raw tinplate to the final assembly of the locking mechanisms, we monitor and record tolerances at every step of production.
We work closely with your design team to translate your brand identity onto metal. Whether you need custom size adjustments, specific structural shapes, or high-end embossing, our engineers help construct a compliant, eye-catching container.
Key considerations for supply chain directors sourcing child-resistant metal packaging.
For procurement directors and supply chain managers in the pharmaceutical, nutraceutical, and legal cannabis markets, packaging sourcing requires managing regulatory risk and logistics. A compliant packaging partner must provide more than low unit costs; they must ensure chemical purity, compliance with safety certifications, and stable production capacity. In close cooperation with third-party testing labs, CR Tin guarantees that all materials meet international food contact standards.
We use an Acceptable Quality Limit (AQL) of 1.5 for major defects and 4.0 for minor defects. This ensures shipment consistency, reducing potential downtime during automated packaging runs. Our manufacturing facilities are open to independent third-party audits. This provides transparency for enterprise clients who require strict compliance verification for their supply chains.
Frequently asked questions about child-resistant tins, compliance, and custom manufacturing.
A tin box is designated child-resistant when it satisfies the requirements of the Poison Prevention Packaging Act (PPPA) according to 16 CFR § 1700.20.
