International shipping involves transporting custom-manufactured parts across borders using air, sea, or courier services. Choosing the right shipping method affects delivery time, cost, customs clearance, and overall project schedule.
Express 3–5d · Air 5–9 · Sea 20–35 (typical ranges).
Transit times vary by route and customs; we publish ranges and provide backup plans for exceptions.

International trade terms (Incoterms) define who is responsible for freight, customs clearance, and duties. Here are the three terms most first-time buyers actually need to know.
If you are unsure which Incoterm to choose, DDP is usually the simplest option for first-time buyers.
Still not sure? Share your route, weight/volume and target arrival date, and our team will recommend the best option. Contact our logistics team.
Clear documentation and the right Incoterm keep your shipment moving smoothly through customs. These quick answers cover the most common questions buyers have about paperwork and responsibilities.
A commercial invoice, packing list, and shipping labels or airway bill are typically required. Depending on the destination and Incoterm, you may also need certificates of origin, material certificates, or import permits.
Responsibility depends on the selected Incoterm. Under DDP, the seller arranges customs clearance and pays duties and taxes. Under EXW or FOB, the buyer (or the buyer’s broker) is responsible for import clearance and duty payment.
Yes. We can prepare the commercial invoice, packing list, HS code suggestion and export declarations based on your order information. For special licenses or destination-specific documents, we coordinate with your freight forwarder or customs broker.
No. For compliance and insurance reasons, we always declare the true transaction value and accurate HS codes. This protects you from penalties, shipment holds, and issues with future imports.
International logistics can be unpredictable—weather, customs inspection, peak season, and carrier delays all create risk. Here’s how we minimize issues and protect your shipment end-to-end.
We use foam, anti-static bags, VCI protection, corner guards, and double-wall cartons. For heavy items, we use ISPM-15 certified wooden crates.
Each shipment includes labeled cartons, HS codes, detailed packing lists, and compliant commercial invoices that reduce customs delays.
We work with vetted forwarders for DHL / FedEx / UPS, air cargo consolidators, sea freight agents, and rail specialists for stable delivery.
Before dispatch, we verify part quantities, packing integrity, batch labeling, and include photos/videos upon request for transparent confirmation.
Clear role definitions and authority boundaries ensure smooth order execution, quality control, and on-time delivery across the entire manufacturing and logistics workflow.

Typical ranges are 2–5 business days for express courier, 5–10 business days for air freight, and 25–40 days for sea freight depending on route, season and customs clearance.
For small urgent parcels, express courier balances speed and cost. For 50–300 kg time-sensitive shipments, air freight is usually best. For large or heavy cargo, sea freight offers the lowest cost per unit even though transit time is longer.
