Samples & Minimum Order Quantity (MOQ)
1. Do you provide samples? What is the sample cost and shipping fee?
Yes, we recommend sample testing before bulk orders. Standard in-stock samples require a low sample fee; custom samples may incur development costs. Shipping is calculated by destination and carrier — use your own freight account or prepay through us. Sample fees are fully refundable when you place a qualifying bulk order, making it risk-free to evaluate quality, adhesion, conductivity, and device compatibility.
2. What is your Minimum Order Quantity (MOQ)? Do you support mixed batch orders?
MOQ varies by product type and customization. Standard off-the-shelf TENS electrode pads start from a few hundred pairs per model. Fully customized products (custom molds, special materials, branded packaging) may require higher minimums. We support mixed batch orders — combine multiple sizes, shapes, or connector types in one production run to meet MOQ while diversifying your product lineup.
3. Do you offer volume discounts or tiered pricing for bulk orders?
Yes, we offer tiered pricing and volume discounts for bulk purchases and long-term partnerships. Larger orders reduce per-unit costs through economies of scale in raw material procurement and production. For strategic partners with annual commitments, we negotiate special pricing frameworks and dedicated production scheduling. Share your estimated annual volume with our sales team for the most competitive quotation.
4. How long does sample delivery take?
Sample delivery depends on standard vs. custom TENS electrode pads. In-stock standard models ship within 2–3 business days. Custom-developed samples (custom sizes, shapes, materials, connectors) take 7–15 business days depending on complexity. International express via DHL, FedEx, or UPS takes 3–7 business days to most destinations. We provide tracking numbers as soon as samples ship.

Product Knowledge & Usage Guide
1. What are TENS electrode pads and what are they used for?
TENS electrode pads are conductive adhesive patches that serve as the critical interface between a TENS (Transcutaneous Electrical Nerve Stimulation) or EMS (Electrical Muscle Stimulation) device and the user’s skin. They transmit gentle electrical impulses from the device to targeted muscle groups or nerve endings, enabling therapies such as pain relief, muscle rehabilitation, post-workout recovery, and physical therapy treatments. Each pad consists of a substrate layer (non-woven fabric, silicone, or foam), a conductive layer, a hydrogel or conductive adhesive for skin contact, and a connector (snap or pin) that attaches to the device lead wires.
2. How long do TENS electrode pads last and when should they be replaced?
The lifespan of TENS electrode pads depends on usage frequency, skin preparation, storage, and material quality. Under normal use — 20–30 minutes per session, several times weekly — a high-quality pair typically lasts 20–30 applications. Signs that pads need replacement include reduced adhesion, uneven or weak stimulation, visible drying or cracking of the gel layer, skin irritation, or pads that slide off during treatment. To extend pad life, clean and dry skin before application, avoid touching the gel surface, store in original protective film away from sunlight and heat, and gently rinse the gel with cool water after each use.
3. How to choose the right TENS electrode pads for my device?
Choosing the right TENS electrode pads ensures therapy effectiveness, comfort, and compatibility. Consider four factors. First, connector type: check if your device uses snap-on (3.5mm or 3.9mm) or pin-type (2mm) connectors, and match your lead wire. Second, size and shape: choose sizes for target body area — larger pads (5x10cm) for back and thighs; smaller pads (4x4cm or 5x5cm) for neck, arms, and calves; butterfly for shoulder or lower back. Third, material: non-woven fabric is lightweight; silicone is reusable and durable; hydrogel offers superior skin comfort. Fourth, intended use: clinical use needs higher-grade, latex-free pads, while home-use may prioritize cost.
4. How to store TENS electrode pads to extend shelf life?
Proper storage maintains the adhesion, conductivity, and shelf life of TENS electrode pads. Follow these guidelines. First, store pads in their original protective film or resealable bag after use — this prevents the hydrogel from drying out. Second, store at room temperature (15–25°C) in a cool, dry place away from sunlight, heat, and humidity — extreme temperatures degrade the gel. Third, avoid folding or creasing pads, as this damages the conductive layer. Fourth, keep pads away from sharp objects. Fifth, do not refrigerate or freeze pads unless recommended, as condensation damages the adhesive. Unopened pads last 2–3 years from manufacture.
