For FBA, every inbound shipment from your supplier in Asia needs both a CBM number (for the freight quote) and a chargeable-weight number (for air/express comparison). The CBM also drives FCL vs LCL decisions — under ~15 CBM is usually LCL, above is usually FCL." }, { "q": "Should I enter carton dimensions or product dimensions?", "a": "Always use outer master carton dimensions — the dimensions of the box your supplier actually ships. Freight is priced on what the carrier loads onto the pallet or container, not the size of the product inside. The Amazon FBA carton-size limit (max 25 inches on any side, max 50 lb) is a separate Amazon-side rule, not a freight rule." }, { "q": "How do I calculate CBM for a palletized FBA shipment?", "a": "For palletized shipments, calculate CBM based on the pallet footprint and total stacked height including the pallet itself. A standard 48 × 40 × 60 inch palletized load = 48 × 40 × 60 × 0.0000164 ≈ 1.89 CBM per pallet. Multiply by pallet count for the shipment total. FBA accepts both 48 × 40 (US) and 1200 × 1000 mm (EU/UK) pallet footprints." }, { "q": "What is the FBA carton vs pallet break-even?", "a": "As of May 2026, FBA SPD (Small Parcel Delivery) by floor-loaded carton is cheapest under ~150 kg total weight or ~1.5 CBM. Above that, LTL palletized inbound is usually cheaper per unit. Above ~10 CBM or 6 pallets, ocean LCL or FCL from origin direct to an FBA prep center beats domestic LTL." }, { "q": "Does Amazon charge me for CBM or for weight?", "a": "Amazon does not directly charge inbound CBM — the freight forwarder does, on the China-to-US (or Vietnam/India-to-US) leg. Amazon charges you placement fees and inbound processing on top once the shipment hits an FBA receive center, billed on unit and weight, not CBM." }, { "q": "How many FBA cartons fit in a 40ft HQ container?", "a": "A 40ft HQ holds about 65–68 CBM usable. For a typical FBA master carton of 50 × 40 × 40 cm (0.08 CBM), that is roughly 800–850 cartons. Real-world fit drops 10–15% with palletization since pallets waste vertical space and require aisle clearance." } ], "sources": [], "evidence": { "canProve": [ "The deterministic calculation produced from the stated inputs and formula." ], "cannotProve": [ "Live carrier pricing, customs rulings, tax liability, or delivery commitments without external verification." ], "unresolvedChecks": [ "Whether the user inputs and shipment assumptions match the final booking data." ] }, "relatedTools": [ { "slug": "cbm-calculator", "title": "CBM Calculator — Cubic Meter Volume for Freight Shipping", "url": "https://cargomath.com/tools/cbm-calculator/" }, { "slug": "fba-shipping-calculator", "title": "Amazon FBA Shipping Calculator — China to US Inbound Freight (Air / LCL / FCL)", "url": "https://cargomath.com/tools/fba-shipping-calculator/" }, { "slug": "chargeable-weight", "title": "Chargeable Weight Calculator — Air, Ocean LCL, and Courier", "url": "https://cargomath.com/tools/chargeable-weight/" }, { "slug": "pallet-cbm-calculator", "title": "Pallet CBM Calculator — Volume by Pallet Size, Stack Height, and Count", "url": "https://cargomath.com/tools/pallet-cbm-calculator/" }, { "slug": "fcl-vs-lcl-calculator", "title": "FCL vs LCL Calculator — Break-Even Volume for Ocean Freight", "url": "https://cargomath.com/tools/fcl-vs-lcl-calculator/" } ], "machine": { "summary": "Calculate FBA inbound shipment volume in cubic meters from outer carton or pallet dimensions and quantity, for ocean LCL, air, and LTL quoting.", "inputs": [ { "name": "length", "type": "number", "required": true, "unit": "cm|m|in|ft", "description": "Outer master carton or palletized load length." }, { "name": "width", "type": "number", "required": true, "unit": "cm|m|in|ft", "description": "Outer master carton or palletized load width." }, { "name": "height", "type": "number", "required": true, "unit": "cm|m|in|ft", "description": "Outer master carton or palletized load height (include pallet height for pallets)." }, { "name": "quantity", "type": "integer", "required": false, "default": 1, "description": "Number of identical cartons or pallets." }, { "name": "unit", "type": "string", "required": true, "enum": [ "cm", "m", "in", "ft" ], "description": "Unit shared by the dimensions in this line item." } ], "outputs": [ { "name": "cbm", "type": "number", "unit": "m3", "description": "Total shipment volume in cubic meters." }, { "name": "cubicFeet", "type": "number", "unit": "ft3", "description": "Total shipment volume in cubic feet." } ], "formula": "cbm = normalized_length_m * normalized_width_m * normalized_height_m * quantity", "limitations": [ "Returns volume only and does not price the FBA inbound shipment.", "Uses outer master carton or palletized dimensions, not Amazon unit-level dimensions.", "Does not check Amazon FBA carton-size or weight rules (max 25 in per side, max 50 lb for SPD)." ], "quoteAction": { "intent": "freight-quote", "url": "https://cargomath.com/quote/", "specUrl": "https://cargomath.com/quote/spec.json", "method": "POST" } }, "contact": { "email": "helen@honourocean.com", "whatsapp": "8618923724899", "quotePage": "https://cargomath.com/quote/" }, "updatedAt": "2026-05-12" }
