FAQs (Frequently Asked Questions for Buyers)
We’ve compiled the most common questions from global buyers to help you make informed procurement decisions, including key concerns about shipment inspection:
Q: How do you ensure product quality during shipping?
A: We use waterproof paper + steel straps for bundle packing, and wooden pallets for fragile orders to prevent scratches, dents, or rust.
We also add anti-rust oil for long-distance shipping.
Additionally, we can purchase shipping insurance for your order to avoid losses due to transportation accidents. Strict shipment inspection before loading further ensures product quality.
Q: Can I arrange third-party inspection (e.g., SGS/BV) before shipment?
A: Yes. We fully cooperate with third-party inspection agencies.
You can designate SGS, BV, or other trusted agencies to conduct on-site inspection before shipment.
We will provide all necessary documents and assist the inspection team to complete the process efficiently—no extra fees for our cooperation.
Q: What payment terms do you support for international buyers?
A: We support flexible payment terms: TT (30% deposit + 70% before shipment), L/C at sight, and Western Union.
For long-term cooperative buyers, we can provide more favorable payment terms (e.g., 10% deposit + 90% after receipt of goods).
