Beyond price, the most critical factors are compliance with industry standards, quality assurance protocols, production capacity, and on-time delivery reliability. You should prioritize suppliers with official certifications (HDMI LA, USB-IF, UL, CE, RoHS, REACH) and verifiable test reports for signal integrity, shielding effectiveness, and durability.
These certifications ensure the cable meets mandatory safety, environmental, and performance standards for regulated markets such as North America and the EU. HDMI LA certification guarantees adherence to signal integrity and interoperability specifications.
Request documented test reports covering: insertion loss, return loss, impedance control (100Ω ±5% for HDMI), shielding effectiveness (triple-layer: foil + braid + Mylar), bend endurance (minimum 10,000 cycles), connector plating durability (plug/unplug cycle testing), and electrical stress tests. Top-tier suppliers maintain traceability systems across production batches and conduct in-house testing at every stage—from raw material inspection to final packaging.
Key metrics to request: factory size (≥5,000㎡ recommended for bulk orders), workforce size (100+ employees suggests robust operations), annual revenue (>$500K indicates stability), on-time delivery rate (≥96% is industry benchmark), reorder rate (>20% signals customer satisfaction), and response time (≤2 hours ideal), factory audit reports, sample test data etc.
Request construction details including certified bare copper conductors (typically thick conductor for durability and low signal loss), triple-layer shielding (foil + braid + Mylar) for EMI/RFI rejection, gold-plated connectors for corrosion resistance and optimal conductivity, and durable jacket materials (PVC, TPE, braided, or plenum-rated for specific applications). Ask for sample test data on impedance, shielding effectiveness, and voltage withstand.
We typically offer good after-sales service. We have good return/replacement policy for defective batches, technical support availability and whether they conduct post-sale batch tracking.
We usually ship via sea freight from major ports (Shenzhen Yantian, Shekou) with lead times of 20-40 days depending on destination. Air freight is available for urgent orders but significantly increases costs. The incoterms is typically FOB Shenzhen or EXW.
TLD's Headquarters is located in Shenzhen with manafacture in Dongguan and other province of China.Guangdong, who is the global hub for HDMI and USB cable manufacturing due to its integrated supply chain—proximity to raw materials (OFC, PVC, gold-plated connectors, fiber-optic components), precision tooling, testing labs, and export logistics hubs. This ecosystem enables rapid prototyping, competitive pricing, scalability for bulk orders, and efficient global distribution. Shenzhen leads in R&D for next-gen standards (HDMI 2.1, USB4), while Dongguan excels in high-volume OEM/ODM production. And TLD is the leader HDMI & USB manufacture in Guangdong and work with ZTE, Skyworth etc.
Copper is a primary cost driver for HDMI and USB cables. Most suppliers price based on daily copper market rates and may include a “copper surcharge clause” in contracts. Buyers can mitigate risk by: locking in prices for fixed periods (30-90 days), negotiating price adjustment formulas tied to copper indices, placing larger consolidated orders to secure volume pricing, or requesting monthly price updates. Always ask whether quoted prices are fixed or floating and for how long the quote is valid.

Changping， Dongguan.
Yes.
Yes, we provide samples. For new customers, we usually charge the sample cost & shipping fee, refundable against bulk order. And for old customers, samples cost can be negotiated depends on different projects. Evaluate samples against your own devices and test equipment before approving mass production.
Our payment terms usually is 30% deposit upon order confirmation and 70% balance before shipment (T/T bank transfer). Letters of Credit (L/C) are also accepted but may incur additional banking fees and longer processing times. Always negotiate terms in writing before production begins.
MOQs vary by customization level.
Standard off-the-shelf cables may have MOQs as low as 100-500 pieces.
Customized orders (specific lengths, connector plating, jacket colors, logos, branded packaging) typically require higher MOQs—anywhere from 5,000 to 10,000 units depending on complexity.
Manufacture.
Our standard lead times vary by order size and customization complexity:
Sample production: 3-7 days (standard cables) or 7-14 days (customized).
Mass production: 15-25 days for 5,000-20,000 units; 25-30 days for 50,000+ units.
Custom orders (branded packaging, specific lengths, custom connector plating) typically add 5-10 days.
Always add buffer time for Chinese holidays (e.g., Chinese New Year, National Day) when factories close for 7-14 days and logistics networks slow significantly.
