Logistics is where deals go wrong after everything else went right. An incorrect HS code adds 25% tariff. Missing battery documentation grounds a shipment for 3 weeks. A factory that books the cheapest forwarder ships your goods via 3 transshipment ports with no tracking.

We’ve seen all of it. We prevent it by controlling the logistics chain from factory gate to your warehouse door.

What We Handle

Freight forwarder coordination We work with 3–4 vetted forwarders in Shenzhen and Dongguan. For most shipments, we get competitive quotes from 2–3 of them. We handle booking, pickup scheduling, and cargo handoff documentation.

Export documentation

  • Commercial invoice (correct value, correct HS code)
  • Packing list (accurate weights and dimensions matter for customs)
  • Bill of Lading / Air Waybill
  • Certificate of Origin (when needed for duty reduction)
  • Battery/dangerous goods declarations (for lithium products)
  • FCC/CE documentation for customs clearance in destination country

Shipping modes

  • Sea freight LCL/FCL: 18–35 days, cheapest for volume. We optimize consolidation for LCL.
  • Air freight: 5–10 days, 5–10x more expensive, right choice for time-sensitive or high-value/low-weight shipments.
  • Express courier: 3–7 days, for samples and small batches under 50kg.
  • Rail (China–EU): 18–22 days, middle ground in price and transit time for EU buyers.

Import advisory We provide HS code suggestions, duty rate estimates, and connect you with customs brokers in your country. We don’t file import customs (that requires a licensed broker in your jurisdiction), but we make sure the documentation they need is correct.
