What is NMFC? / 什么是NMFC？

4 Factors That Determine Freight Class / 决定货类的4个因素

Density vs NMFC: Which Takes Priority? / 密度和NMFC哪个优先？

Example / 举例： A shipment of glass panels might calculate to Class 70 by density alone, but because glass is fragile (high handling + high liability), its NMFC classification is Class 85–150. If you ship at Class 70, the carrier will reclassify and charge you the difference.
例如：一批玻璃板按密度可能算出Class 70，但因为玻璃易碎（搬运难度高+责任风险高），NMFC实际分类是Class 85–150。如果你按Class 70发货，承运商会重新分类并收取差价。

Best Practice / 最佳做法

1️⃣ Know your NMFC code — search it on this page or ask your supplier. This is the most reliable way.
     查清你的NMFC编码——在本页搜索或向供应商确认，这是最可靠的方式。
2️⃣ If you don't have an NMFC code — our system will calculate class based on density. This works well for most standard cargo.
     如果没有NMFC编码，系统会根据密度自动计算Class，对大多数标准货物够用。
3️⃣ Watch for exceptions — fragile, battery, liquid, loose/unboxed items may need a higher class regardless of density.
     注意例外情况——易碎品、含电池、液体、裸装货物即使密度低也可能需要更高等级。
4️⃣ Accurate dimensions & weight matter most — if your measurements are accurate, reclassification risk is low.
     尺寸和重量的准确性最重要——测量准确，被重新分类的风险就低。
