Absolutely — OEM and ODM are the core of our business. In 2025, 78% of our B2B orders involved some degree of customization.

OEM (your design, our production): You provide a spec sheet, technical drawing, or reference sample. We handle material sourcing, prototyping, tooling setup, and mass production under a signed Non-Disclosure Agreement. We have completed OEM runs for brands including Zensah and RFE International.

ODM (we design, you brand): Choose from our catalog of 200+ proven designs. We adapt materials, colors, logos, and packaging to your brand identity. Our in-house engineering team of 15 professionals can deliver the first ODM prototype in 10 to 14 business days.

Custom options include logo heat-transfer / embroidery / screen printing, Pantone color matching, custom material blending (neoprene / nylon / polyester / cotton), retail packaging design, and barcode / UPC assignment. We have completed 85+ OEM/ODM projects for clients across 50+ countries.

Yes — we provide up to 5 free stock samples to qualified B2B buyers. You only cover the courier cost.

Stock samples: Dispatched within 3 to 5 business days from our ready-stock of 30 top SKUs. Shipping via DHL, FedEx, or UPS — typically $35 to $65 depending on destination and package weight.

Custom / OEM samples: Lead time of 7 to 12 business days. A development fee of $40 to $120 applies (varies by complexity), and this fee is 100% refundable upon placement of your first confirmed bulk order.

Every sample ships with a measurement and quality checklist so your team can verify dimensional accuracy, stitch density, material composition, and packaging compatibility before approving production.

Our lead times are structured into three tiers:

• Stock samples — 3 to 5 business days from confirmation. Shipped via express courier with tracking.
• Standard bulk orders — 15 to 20 business days from deposit confirmation. This covers material staging, cutting, sewing, assembly, QC inspection, and packing.
• Custom OEM/ODM bulk orders — 25 to 35 business days. Extended time accounts for material sourcing, color matching, tooling (if needed), and additional QC protocols. A custom-molded silicone patellar strap, for instance, requires 5 to 7 extra days for mold fabrication.

Our on-time delivery rate for the first half of 2026 stands at 94.7%, measured against confirmed ETD. Sea freight from Shanghai/Ningbo to Los Angeles: 18 to 22 days (LCL or FCL). To Rotterdam: 28 to 32 days. Weekly production reports with photos are provided throughout the cycle.

Our factory and products are certified for multiple international markets:

ISO 9001:2015 — Quality management system certified, with annual SGS surveillance audits.

BSCI — Our Zhejiang partner factory (Huzhou Wuxing Hengyu Glove Co., Ltd.) holds BSCI Certificate #24-0302138 issued by amfori BSCI. Our Jiangsu partner factory holds BSCI Certificate #26-0374719 issued by amfori BSCI. Combined manufacturing footprint: 50,000 m² with a 120-person workforce.

CE Marking (EU) — 38 product series carry CE marking under the applicable EU Medical Device Regulation framework, covering compression supports, ankle braces, and knee sleeves.

FDA (United States) — We are a registered Class I medical device manufacturer with the U.S. FDA. All US-bound shipments include FDA-compliant labeling and customs documentation.

Material safety — Third-party test reports from Intertek and SGS cover ISO 10993 biocompatibility, REACH compliance, latex-free declaration, and phthalate-free declaration for our neoprene and silicone-based products.

We also assist with Health Canada, TGA Australia, and ANVISA Brazil registration support on a per-project basis. Customs packages (certificate of origin, packing list, commercial invoice, bill of lading) are provided with every shipment.

We offer flexible payment options designed for international B2B transactions:

Sample orders — 100% prepayment via T/T bank transfer, PayPal, or credit card (Visa / Mastercard). We process and acknowledge payment within 24 hours.

Bulk production (first-time buyers) — 30% deposit to initiate production, 70% balance before shipment (against scanned copy of the bill of lading). Our bank is HSBC Shanghai; wire instructions are provided on your proforma invoice.

Established repeat buyers — After 3 to 4 successful transactions with a cumulative order value above $50,000, we can discuss L/C at sight or net-30 terms on the balance.

For orders exceeding $20,000, we accept irrevocable confirmed letters of credit. 95% of new B2B accounts are set up and ready to order within one business day of submitting the required company information.

Quality is built into our process through a four-stage inspection protocol:

Stage 1 — Raw material QC. Every incoming batch of fabric, neoprene, silicone, elastic webbing, and hardware is tested for thickness, tensile strength, color fastness, and dimensional stability before release to production.

Stage 2 — In-process inspection. Line supervisors conduct dimensional tolerance checks at ±1.5 mm and seam strength tests above 15 kgf every 200 units during cutting, stitching, and assembly.

Stage 3 — Final random sampling (AQL). We follow AQL 2.5 normal level II per ANSI/ASQ Z1.4. For a 5,000-piece order, our QC team randomly samples 315 units. Acceptance criteria: critical defects = 0, major defects less than 7, minor defects less than 14. Lots exceeding these limits are returned for 100% re-sorting before re-inspection.

Stage 4 — Third-party inspection (optional). SGS, Bureau Veritas, or TUV inspectors are welcome at your cost. We provide a dedicated on-site inspection area and 48-hour advance sample preparation. Our third-party inspection pass rate over the past 12 months is 97.3%.

Every shipment includes a Certificate of Quality signed by our QC manager with lot-specific test results, plus a 12-month warranty against manufacturing defects on all B2B orders.
