# 木材货物的积载因数：IMO 区间及其用法

积载因数 = 每吨立方米数：它告诉你船舱或集装箱的哪些信息、IMO CSS Code 表 4.1 对木材货物的区间、一个算例，以及木材甲板货基础。

## 积载因数告诉你什么

积载因数是 **SF = 货物体积 ÷ 货物质量（m³/t）**——一吨货物在舱内（含垫木与空隙）占用的立方米数。SF 低说明货物密实、先满重量；SF 高说明货物轻泡、先满空间。对舱容 1,850 m³、载重量 1,250 t 的船，SF 2.0 的货物在 925 t 就装满货舱——远在重量约束之前就先受空间约束。

## 木材的 IMO CSS 表 4.1 区间

| 货物 | SF (m³/t) |
| --- | --- |
| 锯材，方端 | 1.8–3.4 |
| 锯材，非方端 | 2.0–3.8 |
| 刨光木材 | 2.4–2.8 |
| 热带原木，新鲜 | 1.3–2.8 |
| 松木原木，新鲜 | 1.4–2.2 |
| 原木，去皮/窑干 | 1.2–3.3 |
| 胶合板（估算） | 1.7–2.1 |
| 平板包装木材（估算） | 3.0–5.0 |

## 算例

一批刨光松木：配载计划 520 m³，水尺计重 200 t → SF = 520 ÷ 200 = **2.60 m³/t**——落在刨光木材区间（2.4–2.8）内，也在一般锯材区间内。如果数字落在该申报货物的所有区间之外，就该怀疑测量：体积错、含水率错，或舱里装的货不对。

## 木材甲板货概要

IMO CSS Code 为木材甲板货单列条款：按货堆设计的绑扎与立柱、最大堆高、供船员通行的安全走道，以及计入吸水与结冰的稳性校核。上面的区间帮你估算批量；装载计划本身属于船长和船级社规则——SF 只是这场对话的输入，不能替代对话。

## 从积载因数到订舱

用 SF 给运费做合理性检查：SF 远高于行业常规的货物占用的是紧俏舱容，定价也应相应体现。集装箱航段的同一逻辑由平衡密度承接——见 [体积满载还是重量满载：哪个上限先拦住你的集装箱？](https://nestingcalc.com/cn/guides/container-loading-cube-out-weigh-out/)——而 [积载因数](https://nestingcalc.com/cn/stowage-factor-calculator/) 用你的体积和质量计算 SF，并标出货物落在哪个 IMO 区间（以及哪些估算行）。
