混合空海运输让你保持不断货,同时不牺牲单件利润。在这一打法中,约10%的件数走空运,覆盖两周销售窗口;其余90%搭配周三ETD的快船航线,把速度用在刀刃上、在不敏感处控成本。对于面临更紧ROAS和高资金成本的FBA与DTC品牌,这种拆单分流是最干净的库存保险。

为什么混合优于全空或全海用于FBA补货

逻辑很简单:全空可以保住销量却烧钱;全海可以保利润却冒断货与排名下滑的风险。本案中,供应商已将全部货物按海运打包并贴标,而零售节奏要求两周内不断货。飞一小批即可覆盖空档期;大头走加急海运,迅速恢复充足在库周数。

成功要点:

  • 约10%的件数走空运,覆盖10–14天销售窗口
  • 90%走更快的海运服务(每周三ETD),尽量缩短空档
  • 端到端DDP到Amazon:含清关、关税、预约与末端配送
  • 在我们起运仓按EXW进行原产地拆分,空运重贴标、海运合并打托

案例:从中国到美国FBA,EXW交货,10%空运 / 90%快船

一家季节品进口商将货物按EXW交给我们。我们从工厂提货,所有箱到达起运仓后即刻拆分:空运小批当天放行;其余订上周三出发的快船服务。

SINO Shipping(自1989年起运营,8个中国办公室,NVOCC / Class A牌照)在内控完成的执行步骤:

  • 工厂提货至就近仓库
  • 当天在起运仓拆分,全程摄像与点数
  • 空运部分重贴承运人合规与FBA路由标签
  • 海运部分打托与拼整,赶上加急截关
  • DDP清关代理与关税垫付
  • 两条腿均完成Amazon FC预约与派送

Expedited ocean (DDP)~18–25 days after departureBaselineWeekly Wednesday ETDs; faster devanning and dray
Standard ocean (DDP)~28–40 days after departure~0.8x–0.9xCheaper but stretches the stockout risk window

空海混合:到底该飞多少?

用简单的覆盖模型来设定空运抽出量。目标是覆盖从今天到海运货最早可能FC入仓之间的天数,再加上收货波动缓冲。

  1. 估算覆盖空档:
  • 海运门到FBA时长(天):O
  • 当前Amazon在库天数 + 在途小包裹(天):C
  • 收货波动缓冲(天):B(通常2–4)
  • 需覆盖空档 = max(0, O − C + B)
  1. 将空档转为件数:
  • 日销速度(件/天):V
  • 需空运件数 = V x 空档
  1. 设定抽出占比:
  • 抽出% =(需空运件数)÷(总出货件数)

示例(取整):

  • O = 22天(加急海运)
  • C = 10天(在库/在途)
  • B = 3天缓冲
  • 空档 = 15天;若V = 20件/天,则空运件数 = 300
  • 若总出货 = 3,000件,抽出 ≈ 10%

可复用的决策框架:

VariableWhat to plug inPractical range
Daily velocity (V)Last 28 days excluding promo spikesUse p50 or p60, not peak days
Ocean door‑to‑FBA (O)Route‑specific, confirmed weeklyExpedited: 18–25; standard: 28–40
On‑hand cover (C)FC + known inbound checked‑inVerify FC receiving lag
Buffer (B)Receiving + appointment variability2–4 days typical
Carve‑out target (%)(V x (O − C + B)) ÷ Total unitsOften 5%–20%

操作手册:拆分、重贴标、两条腿同流启动

痛点在于:工厂已按海运为全部纸箱贴标。进口商需要快速抽出空运,而不在上游返工。由于我们掌控原产地操作,在自有仓内完成拆分与重贴标,当天即可双线并发。

可复用的逐周流程:

提速关键:

  • 原产地自有仓操作:拆分与重贴标不等第三方
  • 稳定空运舱位与快船每周班期已锁定
  • 针对Amazon优化的DDP流程:我们负责预约,你看到check‑in

DDP到Amazon:一张发票,零交接

混合路线最怕多手交接。我们坚持端到端DDP,让财务与运营更清爽:

  • 每条腿(空/海)单一价格逻辑,含清关、关税与至FC末端配送
  • 一套运输单证与账单信息;通过自有代理项目垫付关税
  • 目的地团队处理Amazon预约交付

我们在原产地常规提供的增值服务:

  • FNSKU/单件贴标
  • 纸箱贴标与按运输方式拆分后的重贴标
  • 加急海运打托与整合
  • 若供应商贴标不符合FBA标准的返工工时

SINO优势:自1989年运营,覆盖中国8个办公室,持有NVOCC / Class A牌照,我们在快船服务保有固定舱位,并维持稳定空运配额。因此小批空运当天可走,大货也能赶上每周班期。

混合规划的成本–速度护栏

无需精确报价也能决策。先用比例与时间窗评估,再申请舱位与配额。

OptionDoor-to-FBA windowRelative cost per kgWhen to use
Small air carve‑out~10–15 days after take‑off≈ 3xCover 1–3 weeks of sales to prevent stockout
Expedited ocean (bulk)~18–25 days after departureBaselineRestore healthy weeks of cover without margin damage
Standard ocean~28–40 days after departure~0.8x–0.9xWhen you have 4–6 weeks’ cover and low urgency

锁定拆分前的两项核对:

  • 空运抽出能否覆盖至海运最早现实入仓的全部需求?
  • 两条腿落地后,是否能留出4–8周在库,降低补货频次?

底线

空海混合让你同时守住营收与现金。空运约10%补空档;其余90%走加急海运(周三ETD)。当ROAS收紧、资金成本上升时,这是P&L负责人需要的杠杆。若你想要一条按销量与FC配置量身定制的路线,SINO可在中国8个办公室任一处实现自入仓24小时内拆分、重贴标与双线启运。

DDP
Delivered Duty Paid. Seller pays all costs to the buyer's door, including clearance, duties, and Consumption Tax. True DDP means the recipient pays nothing at delivery.
ETD
Estimated Time of Departure. When a vessel or flight is scheduled to leave origin.
EXW
Ex Works. Seller makes goods available at their premises; buyer arranges pickup, export clearance, freight, and everything beyond. Risk transfers at the factory gate—the earliest of all Incoterms.
loading dock
Raised platform at the warehouse where trucks back in for level unloading. No dock = need lift-gate or ramp; dock-to-dock is the cheapest last-mile option.
palletize
Load cargo onto pallets for handling and transport. Often optional at CFS; sometimes mandatory for Japan or specific carriers.
pickup
Factory collection. Truck books, loads at origin, and transports cargo to the CFS, CY, or airport. Distance, multi-supplier stops, and cargo readiness affect cost.
