Frequently Asked Questions
Everything you need to know about working with Kenier Co
Part 1: Adult Toys & Tech
Adult products, devices, and Bluetooth technology
What is the difference between TPE, TPR, and Medical-grade Silicone?
Cheap TPE/TPR are porous, sticky, and trap dust and bacteria. Medical-grade silicone costs slightly more but is non-porous, hypoallergenic, and effortless to clean.
How can I prove to my customers that the silicone is phthalate-free?
Kenier Co can provide third-party RoHS, REACH, and California Proposition 65 test reports for tested silicone materials or representative products. These reports verify compliance with the restricted phthalates covered by the applicable test method. Our silicone products are manufactured using approved material specifications and the same controlled production standards. Because third-party testing adds cost, every SKU is not automatically issued a separate report. If your market, platform, or retailer requires testing for a specific model, color, brand name, or production batch, we can arrange additional testing before mass production.
Does the silicone smell bad out of the box? How to fix it?
Absolutely not. To guarantee an odorless, premium unboxing experience, Kenier Co utilizes a rigorous post-curing process. Every silicone product undergoes secondary vulcanization in industrial ovens at 200°C for 6 hours. This completely eliminates volatile organic compounds (VOCs), ensuring absolute purity and zero odor.
Do adult wellness products need FDA approval in the United States?
The answer depends on the product's intended use, labeling, and marketing claims. A product sold only as a general adult novelty or wellness item may follow a different regulatory pathway from a product promoted for diagnosis, treatment, mitigation, or another medical purpose. For each project, the buyer should confirm the intended claims and regulatory pathway with a qualified US compliance adviser. Factory certificates or material reports do not by themselves mean that the finished product is FDA approved.
What certifications do I need for Amazon FBA?
To successfully pass Amazon FBA's strict Hazmat review, battery safety documents are mandatory. Kenier Co provides standard UN38.3 and MSDS reports to guarantee smooth warehouse entry. Furthermore, to support your global expansion into strict EU markets, Kenier Co proactively supplies comprehensive RoHS and REACH certifications, ensuring zero compliance delays.
What information should be checked before a US compliance review?
Buyers should first confirm the product's intended use, claims, materials, electronics, battery, labeling, and supporting documents. Requirements differ by product type and sales channel. Kenier Co can provide the available factory and product documents for a confirmed model, while the buyer's regulatory adviser should determine the final US pathway and any additional testing or submissions.
CE, RoHS, FCC, UN38.3—which ones are mandatory for Bluetooth toys?
Mandatory Bluetooth certifications include FCC for the US, CE for Europe, and RCM for Australia, TELEC for Japan, TRA for Middle East, and ICASA for Africa. Kenier Co ensures strict global RF compliance.
Public mold vs. Private mold: What is the difference in cost and risk?
Public molds are free but risk high competition. Private molds require investment but guarantee exclusive IP. Kenier Co recommends beginners start with public molds and customized color, packing box.
How much does it typically cost to open a new silicone mold?
Costs depend on structure. A full liquid silicone mold is around $6,450, while a liquid silicone + PC/ABS mold costs about $7,540.
How quiet are your motors under maximum power? Are they under 50dB?
Absolutely. Kenier Co easily beats 50dB. Our advanced N20 and R180 tungsten-weighted motors achieve an ultra-quiet 35dB, even at maximum power.
Is your IPX7 waterproof rating just 'splash-proof' or truly submersible?
Truly submersible. Kenier Co guarantees bathtub safety utilizing a seamless full liquid silicone wrap and dual-protected magnetic charging. This glue-free design completely prevents heat-induced micro-leaks, ensuring absolute long-term IPX7 reliability.
