  "description": "Calculate ocean freight dimensional weight and LCL revenue tons using 1 CBM = 1000 kg, then compare CBM with actual metric tons under W/M.",
  "answer": "Ocean freight dimensional weight for LCL is CBM x 1000 kg, but billing is normally W/M revenue tons: the forwarder charges the higher of total CBM or actual weight in metric tons, often with a 1.000 RT minimum.",
  "audience": "Cross-border sellers comparing ocean LCL quotes and trying to understand why a forwarder bills by CBM, metric tons, or minimum revenue tons.",

  "faq": [
    {
      "q": "How is dimensional weight calculated for ocean freight?",
      "a": "For ocean LCL planning, convert packed volume to CBM and multiply by 1000 kg. Then compare that measurement equivalent with actual gross weight under the W/M revenue-ton rule."
    },
    {
      "q": "Is ocean dimensional weight the same as air dimensional weight?",
      "a": "No. Air freight commonly uses cm3 divided by 6000 or 5000. Ocean LCL usually uses 1 CBM = 1000 kg, expressed as W/M revenue tons."
    },
    {
      "q": "What does W/M mean in ocean freight?",
      "a": "W/M means weight or measurement. One revenue ton is 1 CBM or 1000 kg, and the charge is based on whichever value is higher."
    },
    {
      "q": "When does actual weight beat CBM for ocean LCL?",
      "a": "Actual weight beats CBM when cargo density is above 1000 kg per CBM, such as stone, tiles, liquids, metal parts, and dense hardware."
    },
    {
      "q": "Why does my quote show a 1 CBM minimum?",
      "a": "Many LCL consolidators apply a 1.000 revenue-ton minimum because even small shipments require receiving, CFS handling, documentation, and consolidation work."
    },
    {
      "q": "Does this apply to full container loads?",
      "a": "Usually no. FCL is normally priced per container, while W/M revenue tons are mainly for LCL, breakbulk-style charges, and some local handling items."
    },
    {
      "q": "Should I enter carton or pallet dimensions?",
      "a": "Enter the outer dimensions the CFS or forwarder receives. If goods are palletized, use the full pallet footprint and height including the pallet base."
