1. What products does Ruiyan TechFlex primarily manufacture?
We specialize in high-performance layflat hoses, including TPU layflat hose and NBR layflat hose, plus a full range of compatible hose couplings. In addition, through our long‑term manufacturing partners, we supply diesel generator sets and agricultural machinery — products we select and quality‑control to ensure you receive reliable equipment without the hassle of multi‑supplier coordination.

2. Can I customize hose length, color, or printed markings?
Absolutely. Length, color, and printed markings can all be customized. Because these details affect the production process, our technical team will review your requirements and confirm the final specifications with you before we proceed. Just share your idea, and we’ll work out the solution together.

3. Is there a minimum order quantity (MOQ)?
Yes, an MOQ applies to our hoses. The exact quantity depends on the specific diameter and specification. For a tailored MOQ quotation, please contact our sales team with your target size and length — we always try to accommodate reasonable requests.

4. Do you offer free samples?
For TPU and NBR layflat hoses, we provide free samples up to 1 meter in length. This allows you to evaluate quality, flexibility, and workmanship before placing a bulk order. For non‑hose products (such as couplings, generator sets, or agricultural machinery), free samples are not available, but we can provide detailed photos, videos, and technical datasheets.

5. What payment terms and trade terms do you offer?
Our standard payment structure is 30% deposit to start production, with the 70% balance settled before shipment. We support EXW, FOB, and CIF (for select regions). For customers in the United States, we also offer DDP service, providing a true doorstep delivery experience.

6. How do you ensure product quality?
Quality is built into our manufacturing system. Our factory operates under a certified management system and holds credentials in ISO 9001 quality management, ISO 14001 environmental management, and ISO 45001 occupational health and safety. Every batch of hose undergoes in‑process inspection and final testing. Components from our partner factories (generator sets, agricultural machinery) are audited by our team to meet the same high standards.

7. What is covered under your hose warranty?
Our TPU layflat hose and hose couplings carry a one‑year warranty against manufacturing defects. Specifically:

• Covered: Surface blistering on the hose body that is confirmed by photo or video evidence and mutually agreed as a material/workmanship fault. In such cases, we replace the affected length free of charge.

• Not covered: (a) Leakage or blistering near a coupling installed by the customer, where improper installation caused the failure. (b) Damage from site terrain wear, sharp‑object punctures, or operation exceeding the rated working pressure.

For warranty claims on generator sets or agricultural machinery, the warranty period and terms are negotiated on a case‑by‑case basis with our sales team.

8. How quickly can you deliver an order?
Delivery times vary with order volume and specifications, so we don’t quote a fixed number of days for all situations. What we can tell you is that our production capacity is backed by multiple manufacturing lines running in parallel, which allows us to respond to your order with genuine speed. Once we understand your quantity and customization needs, we’ll give you a realistic, reliable lead time.

9. What if I need technical support before or after purchase?
Our engineering and sales teams are available by email and instant messaging. We target a response within 24 hours for technical inquiries. Whether you need help selecting the right hose diameter, understanding coupling compatibility, or troubleshooting on‑site, we’re here to support you — before and after the order.

10. Your company is based in China. Do you have experience serving extreme‑climate regions?
Yes, and this is one of our strengths. We have over ten years of experience delivering to Russia, where our TPU hoses perform reliably at ‑50°C. We also serve:

• Southeast Asia: Our hoses withstand high humidity and tropical temperatures without degradation.

• USA & Canada: We understand North American requirements and offer DDP service to the US for a smooth import experience.

No matter your climate, we can recommend a hose formulation and configuration proven in similar conditions.

11. What about generator sets and agricultural machinery — can Ruiyan TechFlex really handle non‑hose products professionally?
Yes. We have long‑term partnerships with specialized manufacturers of diesel generator sets and agricultural machinery. By leveraging these relationships, we handle sourcing, quality inspection, and logistics consolidation. This means you receive equipment that has been vetted to our standards, at prices that reflect our integrated supply chain — without having to deal with multiple factories yourself.

12. How can I get a quote or start a conversation?
