We are a direct manufacturer with over 30 years of production expertise—not a trading company. All core processes, including dyeing, twisting, setting, and winding, are carried out in-house at our own facility. No outsourcing, no intermediaries.

Our polyester sewing thread plant covers 7,500 m² and maintains a stable monthly output of 250–350 tons, supported by a scalable, standardized production system. Our well-organized workshops and scientific scheduling enable us to meet strict quality standards (twist, strength, colorfastness) while flexibly handling orders of varying sizes. Regular orders are delivered within precise timelines. The 7,500 m² space allows ample storage for raw materials, work‑in‑progress, and finished goods, ensuring full-process quality control from yarn receiving to dispatch—whether for bulk orders or small-batch custom requirements.

Yes. We offer full-chain OEM/ODM customization for polyester sewing thread—covering yarn color, spool material/type (paper, plastic, or custom-colored spools), branding (hot stamping, labeling), and complete packaging solutions (inner bag material, single/multi‑roll packing, carton size and strength). We balance customization with cost and delivery efficiency, and samples are available upon request.

Our standard MOQ is 5 cartons, allowing low‑threshold trial orders. To support new clients, we offer a flexible starting MOQ of 3 cartons for first‑time cooperation, so you can verify quality, process compatibility, and market response with minimal risk. We are open to further negotiation based on product specifications, color variety, and packaging needs.

For stock samples (standard colors/specs), delivery typically takes 1–7 business days. Custom samples (color matching, special spools, or tailored packaging) generally require 7–14 business days, depending on complexity—including shade formulation, sample approval, and trial runs. Stock samples are usually free (freight collect); custom samples incur a reasonable fee, which is refundable upon formal order placement. We will provide a written quotation for your confirmation once your requirements are detailed.

We are ISO 9001 certified, ensuring traceable quality control across yarn sourcing, twisting, setting, and final inspection for consistent strength, twist, and colorfastness. To meet diverse international market needs, we are actively pursuing OEKO‑TEX® STANDARD 100 (focusing on harmful substance testing and ecological safety) and GOTS (for organic/eco‑friendly product lines). These certifications are expected in the near future. We are happy to provide test reports or assist with specific market compliance requirements upon request.

We follow a stringent four‑stage quality control process: incoming raw materials are tested for strength and colorfastness; production is continuously monitored, with dedicated checks on dyeing and twisting tension; finished products undergo destructive testing (tensile strength, abrasion, heat resistance) to ensure no breakage or fading; before shipment, we simulate high‑speed sewing conditions to verify smooth thread delivery and joint integrity. Every roll is thoroughly inspected and traceable, so you can use it directly on your machines with confidence.

We strongly recommend bank transfer, Alipay, or WeChat Pay.

Bulk order lead time is generally 15–45 days after deposit confirmation and sample approval, depending on order quantity and our production schedule. We will provide a precise shipping timeline upon order placement and keep you updated throughout the process.
