Understand actual weight, volumetric weight, consolidation and packaging before choosing a route.
Routes commonly compare actual weight with volumetric weight. The official estimator currently explains volumetric weight as length × width × height in centimeters ÷ 6000; route rules can vary.
Compare actual and volumetric weight, packaging choices and route restrictions.
The official estimator says final shipping is commonly expected to fluctuate about ±5–10% from an estimate for self-operated routes. Final packed dimensions, the difference between actual and volumetric weight, route availability and carrier adjustments are named influences. Treat the estimate as a planning range, not a fixed promise.
The estimator explains that DDP routes include tariffs and taxes, so the consignee usually does not need to take action. On non-DDP routes, the recipient may need to provide documents or pay local duties and taxes. Customs inspection delays remain outside a carrier’s direct control.
The official list includes liquids, powders, pastes, gels, glass or ceramic, screens, loose or high-capacity batteries, food, supplements, perishables, illegal or infringing goods and unsafe packaging. Acceptance and insurance can differ by route. Confirm eligibility before purchase rather than after the item reaches the warehouse.
These are service facts, not quality promises. Seller performance, route availability and destination rules still have to be checked for each order.
USFans presents itself as a purchasing agent for links from these marketplaces; the marketplace seller remains the product supplier.
Live product pages state that purchases are handled after payment during this working window. It is not a guaranteed seller dispatch time.
Product pages advertise three to seven free inspection photos. They document visible condition, not authenticity, internal parts or future durability.
A current product notice says buyers dissatisfied after warehouse arrival can apply within five days. Seller acceptance, exclusions and return freight can still matter.
The official beginner guide states a 90-day free storage period, making consolidation possible without implying that every consolidation is cheaper.
The estimator uses length × width × height in centimetres ÷ 6000 for volumetric weight, then compares it with actual weight.
