For orders above approximately $5,000, T/T USD bank wire is recommended to avoid card processing fees.
Yes. T/T USD bank wire is our preferred payment method for professional, wholesale and bulk orders.
It avoids card processing fees, simplifies reconciliation for both parties, and is faster on larger amounts. Contact us at contact@lys-sz.com with your order details — we'll send you our banking details and a manual invoice.
If your country isn't listed at checkout, it means we need to calculate shipping manually for your destination.
Contact us at contact@lys-sz.com with your shopping cart contents and shipping address — we will adjust the order and send a custom payment link.
Yes — sample orders are available for most products. Provide the product name or SKU to our team at contact@lys-sz.com and we'll confirm availability, pricing and dispatch options.
All orders are shipped from our Shenzhen warehouse in China, using trusted international carriers: DHL, FedEx, UPS and EMS.
For larger bulk orders to selected countries, we also offer sea freight as a more economical alternative.
Dispatch time depends on the parts ordered, quantity, and stock availability — we communicate the expected dispatch window as part of your order confirmation.
Transit time once shipped:
Yes. For larger orders to selected destinations, sea freight is available as a more economical alternative to air freight.
It's typically the preferred option above a certain volume threshold or order value. Transit times are longer (typically several weeks depending on the lane) but the cost-per-unit savings are significant on bulk shipments.
Share your destination country, approximate weight/volume and timing in your quote request and we'll come back with both air and sea freight options when relevant.
Yes — we can ship directly to your end customers with no LYS-SZ marketing materials or invoices inside the package.
Contact us with your dropshipping requirements (volume expectations, packaging instructions, custom branding) and we'll set up a tailored arrangement.
If your tracking hasn't updated for more than 48 hours, contact us at contact@lys-sz.com with your order number. We'll follow up directly with the carrier and update you.
Note: international parcels can sometimes show no updates while in transit between hubs (e.g. customs in transit, between regional warehouses) — this is usually normal.
DDP (Delivered Duty Paid) means we handle customs clearance, import duties and VAT — your order arrives at your door with no surprise fees.
DDP is offered as a standard option for US and EU customers, and is also available on request for other countries depending on order size, destination and shipping lane.
Contact us at contact@lys-sz.com before placing your order so we can confirm DDP feasibility and quote the all-in landed cost for your specific destination.
For non-DDP orders, shipments are sent DAP (Delivered At Place): we handle export clearance from China, and the buyer is responsible for import clearance, duties and VAT in the destination country.
The carrier (DHL, FedEx, UPS, EMS) typically handles import paperwork on your behalf and contacts you for any required documentation or payment of duties before final delivery.
Import taxes (VAT, GST, customs duties) are local fees imposed by your country's government on imported goods. Rates vary by country, product category and order value, and are outside our control on DAP shipments.
To avoid them entirely, choose DDP (available for US, EU and other lanes on request) — we pay all duties upfront so you receive your order with no extra charges.
Use our DDP (Delivered Duty Paid) service. With DDP we calculate and pay all import taxes, duties and VAT upfront — no hidden costs, no carrier collecting fees at delivery.
Contact us at contact@lys-sz.com before ordering to request a DDP quote for your destination.
