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?
TPE and TPR offer different softness, elasticity, processing, and price options. Silicone is commonly selected for premium products that require stable quality, controlled curing, and easier cleaning. The right material depends on product structure, target price, intended use, and market requirements. For a deeper buyer-side comparison, see our TPE, TPR, silicone and PVC comparison.
How can I prove to my customers that the silicone is phthalate-free?
These third-party reports verify the restricted phthalates and limits covered by the applicable test methods. Kenier Co uses the same approved silicone grade or supplier standard across its silicone production. Exact-SKU, color, or batch testing can be arranged at the buyer’s cost when required.
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 standardized process helps reduce residual volatile substances and odor while stabilizing the finished silicone.
Who buys pelvic floor and dilator wellness products?
These products are often developed for brands serving postpartum recovery, menopause wellness, pelvic floor training, and professional intimate care channels. Kenier Co supports dilator and pelvic floor wellness projects with size sets, silicone options, vibration or heating features, packaging, and documentation review.
Do adult wellness products need FDA approval in the United States?
It depends on the product's intended use, labeling, and marketing claims. Kenier Co holds ISO 9001 and ISO 13485 quality system certifications. For each project, we can review the selected SKU and confirm what REACH, CE, RoHS, ISO 10993, or other supporting documents are available or required. Buyers should confirm the final US compliance pathway with a qualified adviser.
What are common reasons adult wellness products fail FDA or compliance review?
Common issues include claims that do not match the intended product use, incomplete material or biocompatibility evidence, missing battery or wireless documents, and inconsistent labeling. Kenier Co holds ISO 9001 and ISO 13485 certifications and can provide applicable RoHS, REACH, California Proposition 65, CE, FCC, UN38.3, and MSDS/SDS documents. ISO 10993 testing can be arranged when required.
What certifications do I need for Amazon FBA?
For applicable battery products, Kenier Co can provide UN38.3 and MSDS/SDS documents. Depending on the product and market, RoHS, REACH, California Proposition 65, CE, and FCC documentation may also be available. Amazon can request different documents by listing, product, battery, and fulfillment market.
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.

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 and allow ownership or exclusivity terms to be defined in the tooling and supply agreements.. 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?
Yes. A representative product using an N20 or R180 motor solution measured approximately 35 dB at its highest vibration setting in a quiet test room, with the sound-level meter positioned 20 cm from the product. The applicable report can be provided by email, and final-SKU testing can be arranged when required.
Is your IPX7 waterproof rating just 'splash-proof' or truly submersible?
IPX7 is an immersion rating rather than only a splash-resistance claim. Kenier Co has representative IPX7 test reports for applicable sealed products using full liquid-silicone wrapping and protected magnetic-charging structures. The final rating should be confirmed for the selected product structure.
