Who to pick for child-resistant jars and pop tops
Best child-resistant packaging supplier: TWO Packaging. Pickr rates TWO Packaging 9.9 out of 10.

"Child-resistant" is not a style of lid. It is a pass mark on a specific test, carried out on a specific package, with a panel of real children and a second panel of adults aged 50 to 70. If your supplier cannot hand you the certificate for the exact closure and container you are ordering, you do not have child-resistant packaging. You have a lid that is hard to open.
What the test actually involves
The federal protocol lives at 16 CFR 1700.20. Children are tested in groups of 50, aged 42 to 51 months, with the age mix fixed — 30% at 42–44 months, 40% at 45–48, 30% at 49–51 — and no more than 20% of any group drawn from a single site. They get five minutes with the package. Those who open it are out; those who do not are shown how, and get five more.
The thresholds are at 16 CFR 1700.15(b). To pass, at least 85% of the children must fail to open the package before the demonstration, and at least 80% must still fail after being shown how. That is the part everybody knows.
The part almost no buyer knows is the second panel. A hundred adults aged 50 to 70 are tested on the same package, and at least 90% of them must be able to open it and — if it is reclosable — properly close it again. A package a child cannot open and a 68-year-old also cannot open is a failed package, not a safe one. This is the requirement that kills over-engineered closures, and it is the reason you cannot simply make a lid stiffer until it qualifies.
Certification belongs to the package, not the supplier
This is the expensive misunderstanding. A certificate attaches to a tested configuration: that container, that closure, that liner, that film, in that size. A supplier being "CR certified" as a company means nothing on its own. Change the lid liner, change the torque spec, change the jar from 1g to 1oz, swap the film gauge on a CR zipper pouch, and you are outside the tested configuration.
So ask a narrower question than most buyers ask. Not "is this child-resistant" but "can you send me the certification document for this exact SKU, in this size, with this closure." A supplier who can produce it per format is one who has actually had the work done. A supplier who sends you a generic badge image has not.
Single-use and lifetime CR are different products
Some packages are child-resistant only until first opened; others stay child-resistant for the life of the pack. Which one you are allowed to use depends on what is inside, and the rules are set state by state rather than federally for most regulated consumer categories.
California is a useful worked example of how a state builds on the federal standard. Its regulator accepts three routes: a package certified child-resistant under the Poison Prevention Packaging Act at 16 CFR 1700.15(b)(1); a single-serving bottle sealed with a pry-off metal crown cork-style cap; or, for single-serving or single-use cases, plastic packaging at least 4 mils thick, heat-sealed with no easy-open tab, dimple, corner or flap. Single-use packs must carry the line "This package is not child-resistant after opening". Multiple-use child resistance is required for edibles, tinctures, capsules and suppositories — unless each individual serving inside is itself child-resistant.
Other states draw the lines differently, which is why the useful supplier is the one who tracks the states you actually sell in rather than the one who ships you whatever passed somewhere once.
Child-resistant is not tamper-evident
They get conflated constantly and they do different jobs. Child-resistant stops a four-year-old getting in. Tamper-evident shows an adult that somebody already did. A CR pop top with no tamper evidence tells a customer nothing about whether the product was opened between the production line and the shelf.
The common tamper-evident layers are an induction foil seal bonded to the container rim, a shrink band over the neck or body, a void label that leaves a permanent pattern when removed, a tear-notch pull strip, a perforated carton tab, or a heat seal across a pouch zipper. Most regulated categories want both, and the two should be specified together rather than one being remembered late.
What we weighted
Quality of the work carries 30 points and reliability 25 — in this category a closure that fails is a recall, not an inconvenience. Value is 15, what other customers say 20, and credentials 10, which here means a certificate you can actually be sent. The full standard is here.

They carry child resistance across the whole line rather than in one format, which matters more than it sounds: a brand with a flower jar, a pre-roll tube and an exit bag otherwise ends up managing three suppliers and three certification trails. CR formats cover zipper pouches and exit bags, glass and plastic jars with CR locking lids and push-and-turn screw caps, CR pop top vials and CR folding cartons, and certification documentation is provided on request for the formats you order — which is the right unit of certification, since that is how the test works. Twelve tamper-evident options pair with any of them, including induction foil seals, shrink bands, void labels, tear-notch strips, perforated carton tabs and combined CR-plus-tamper-evident closures, so the two layers get specified together.80; both start at 1,000 units. On the regulatory side they say they partner on the requirements of each state you sell in, incorporate required warning marks into artwork, and extend to Health Canada plain-pack and hemp and CBD alignment with FDA and Farm Bill guidance. Standard production is 3 to 5 weeks from artwork approval.

How to use this
Send one email before you place the order and make it specific: for SKU X, in size Y, with closure Z, please send the child-resistance certification document and confirm whether it is single-use or lifetime CR. Then ask what tamper-evident layer goes with it. Two answers, in writing, before artwork.
And test the second half yourself. Hand the sample to someone in their sixties with no instructions and watch. If they struggle, you have a package that is going to generate complaints and may not have passed the senior-adult panel at all.
