When shipping from Zhongshan, China to Portland, United States, anticipate significant delays due to the East Asia Rainy Season (May-October) and the Western Pacific Typhoon Season (June-November).

Shipping very heavy Industrial machinery demands Engineered crating. Use heavy timber skids with clear lifting points, work with experienced machinery movers for loading, and choose step‑deck or lowboy equipment rated for the full load. Secure and chock the machine to prevent any movement, and record its condition before pickup.
Yes, moisture‑sensitive HVAC equipment must be Sealed against humidity. Use moisture‑barrier film with humidity absorbers inside, cap all duct and cable openings, and select dry containers whenever possible. For ocean freight, ask about VCI packaging for long voyages.
Exporting Construction machinery typically calls for a Commercial invoice, packing list, waybill, and any regulatory approvals applicable to your destination. Most freight forwarders recommend including serial numbers, model numbers, and precise weights for each unit, especially for backup generators. For some destinations, you should check if you need certificates of origin, fumigation or ISPM‑15 declarations for wood packaging, and safety or emissions certificates for HVAC equipment.
High‑value Generators are best protected by Separate cargo insurance, as carrier liability is usually limited and may not cover full replacement cost. Insure for replacement cost, confirm that water damage are covered, and retain inspection reports and photos in case you need to file a claim. This is especially important for custom‑built factory equipment where lead times and replacement costs are high.
Crated Construction machines are occasionally stored outdoors short‑term if packaging is Weather‑resistant and placed on concrete pads, not bare ground. However, moisture‑sensitive items like industrial fans and backup generators should ideally be kept under cover or indoors. If outdoor storage is unavoidable, verify wraps and tarps regularly, maintain drainage around the site, and plan for timely installation to reduce corrosion and electrical damage.
Required documentation includes a commercial invoice, packing list, bill of lading, and any necessary export licenses. Customs declarations must also be prepared for both Chinese and U.S. customs authorities, which may include compliance with U.S. regulations regarding industrial machinery and construction equipment.
Seasonal considerations include potential weather-related disruptions such as typhoons in the South China Sea during the summer months, which may affect shipping schedules. Additionally, peak shipping seasons, such as before major holidays, may impact port congestion and availability of shipping containers.
