海运合约类型全解析：FAK、FIX、BCO、NVOCC、Block Space、COA
跟船公司谈舱位，客户问你签的是什么合约，你能回答清楚吗？
不少货代从业多年，报价时习惯说“我们有合约价”，却难以准确说明合约类型及其与即期价的本质区别。
其实主流海运合约就六种，逻辑清晰、适用场景明确。本文系统梳理，助你精准沟通、专业应答。
FAK — 即期市场价，灵活首选
Freight All Kinds（所有货种统一运价）
船公司面向市场的通用报价，不区分货类，价格随供需波动，等同于现货价。
适用对象：货量不稳定、无固定航线需求、追求操作灵活性的货代或货主；无需长期承诺，即谈即用。
FAK is the open market rate published by carriers, applicable to all cargo types without distinction. It fluctuates with supply and demand — high in peak season, low in off-peak. No long-term commitment required.
FIX — 长期固定合约，锁定成本与舱位
Fixed Rate Contract（固定运价合约）
与船公司签订的季度或年度协议，约定运价及最低箱量（MQC），旺季不涨价、淡季不降价。
核心逻辑：以货量承诺换取价格确定性——船公司保障收入，货方控制运输成本。
未完成MQC可能产生违约责任，需谨慎评估出货能力。
A Fixed Rate Contract locks in a set freight rate for a defined period — typically one quarter or one year. It includes a Minimum Quantity Commitment (MQC). Shippers trade volume commitment for price stability.
BCO — 货主直签合约，价格与舱位最优
Beneficial Cargo Owner Contract（实际货主合约）
年出货量达数百TEU以上的大型货主，绕过货代直接与船公司签约，享受更优运价和优先舱位保障。
对货代的影响：大客户获取BCO资格后，可能自主订舱，货代仅提供报关、拖车等本地服务，盈利模式面临调整。
A BCO Contract is signed directly between a carrier and the beneficial cargo owner — the actual shipper, not a freight forwarder. It typically offers better rates and space guarantees in exchange for high committed volumes (often 200+ TEU/year).
NVOCC 合约 — 货代的核心竞争力来源
Non-Vessel Operating Common Carrier Contract（无船承运人合约）
货代以NVOCC身份与船公司签约，批量采购舱位并分拆销售，形成稳定运价与利润空间。
关键区别：BCO是货主，NVOCC是中间服务商；前者直连船公司，后者整合资源服务中小客户。
An NVOCC Contract is signed between a carrier and a freight forwarder acting as a Non-Vessel Operating Common Carrier. The NVOCC buys space in bulk and re-sells it to smaller shippers. The rate difference between the NVOCC contract and the retail FAK rate is often where forwarders make their margin.
Block Space — 包舱协议，旺季保供利器
Block Space Agreement（BSA，舱位包租协议）
货代预付费用向船公司买断固定舱位，无论是否使用均需履约付费（或承担空舱罚金）。
优势与风险并存：旺季可确保舱位供给，但若货量不及预期，将产生沉没成本。须严格匹配自身出货节奏。
A Block Space Agreement (BSA) allows a forwarder to reserve a fixed number of containers per sailing, regardless of actual use. It guarantees space in peak season but carries financial risk if volume falls short. Unused space is typically charged as dead freight or roll-over penalties.
COA — 包运合同，大宗散货专属方案
Contract of Affreightment（包运合同）
适用于钢铁、粮食、矿砂、化工品等大宗散货，约定周期内总运输量，不绑定具体航次与箱量。
与FIX的区别：FIX多用于集装箱运输、频次固定；COA侧重总量承诺，调度更灵活，常见于干散货、液散货领域。
A Contract of Affreightment (COA) is common in bulk shipping. It commits a carrier to transport a specified total volume of cargo over a defined period, without fixing exact voyage dates. Widely used for commodities like steel, grain, ore, and chemicals where annual volumes are large but shipment timing is flexible.
六类合约对比一览
| 合约类型 | 签约方 | 核心特点 |
|---|---|---|
| FAK | 任何人 | 即期市价，随行就市 |
| FIX | 货代/货主 | 长期固定，承诺箱量 |
| BCO | 大货主直签 | 绕开货代，价格最优 |
| NVOCC | 货代（无船承运人） | 批量买舱转售，赚差价 |
| Block Space | 货代 | 包舱锁位，旺季保障 |
| COA | 大宗货主 | 散货专用，锁定总量 |
核心逻辑：越靠近货主直签、箱量承诺越大，运价越低。
FAK最灵活但成本最高；BCO与COA价格最优但门槛显著；FIX、NVOCC、Block Space则是货代为中小企业争取稳定运力与合理成本的关键路径。
下次客户询问“你们有合约吗”，请明确告知合约类型、有效期及对其出货的实际价值——这才是专业货代的标准应答。
