Carton math before the booking
A package size is not a carton until someone says it is the carton that will be loaded.

Buyers lose money in the gap between a product page and a loading plan. A retail box gets treated as the export carton. A display size gets copied into a freight email because it sat next to the product. Neither mistake is rare.
Item pages on this site do not print a measurement. That is deliberate. A measurement that is not the confirmed export carton is worse than silence, because someone will book against it. This note explains which measurement is which, so the quotation has a place to land.
Which measurement is which
The retail unit is what the shopper holds. The inner pack is what your warehouse splits. The export carton is what the forwarder cubes. The quotation repeats the outer carton after it is reconfirmed. That confirmed carton is the one to book.
A building block gift box, a squishy window box, and a vinyl mailer do not cube the same way even when the toy inside feels similarly 'small'. The pack is the cube. The toy is only part of the pack. If you change the pack after the carton was estimated, the estimate is over.
Weight, air, and the warehouse
Gross weight matters as much as the cube. A light carton that is mostly air is a volume problem. A dense carton is a handling problem. Tell us which one your warehouse hates and we will pack toward that, within what the goods allow. We will not promise both a lavish insert and a dense carton. Those wishes fight.
Inner packs matter to the people who receive the goods, not only to the forwarder. If your dealers must split a carton without destroying the retail boxes, say so. If the goods go straight to a fulfillment shelf, a different inner may be better. The packaging note walks through gift boxes, windows, and mailers.
Then the term
EXW, FOB, and DDP are not moods. They are statements about who owns the goods at which door. We name the port on the proforma. We do not hide origin charges inside a unit price and call it FOB. If the carton is still a guess, the freight is still a guess, and we will say that in the same sentence as the price.
Samples travel by courier. Bulk travels by sea unless you and the calendar truly need air, and air is quoted as air. Do not ask a sea quotation to quietly include air. The ordering guide states the same rule. Use it when a colleague treats the trade term as a preference rather than a door.
What to send before anyone books
Send the destination, the term you think you want, and whether the pack is final. If the pack is not final, say that in the first sentence. We will still talk about the toy. We will not pretend the freight is known. Inspection before shipment checks the packed carton against the approved pack, not against an old estimate.
When the goods and the lane are clear enough to price honestly, send the inquiry. Include the market and the term you want named. Leave the invented carton size out. We would rather measure than inherit a guess.
Before you forward a quotation internally, check that the carton on the page is labeled as the export carton, that the term matches the door you think you are buying, and that nobody has pasted a retail box size into the freight note. If any of those are unclear, ask before the booking. A correction after the goods are at the port is no longer carton math. It is a claim. We would rather have the dull question early.
Ask for the carton in the same units your forwarder uses, and ask whether the weight is gross. A net toy weight will understate the booking. If the quotation shows one carton and your warehouse expects another, reconcile them before the deposit. Mixed goods in one carton should be listed as a mix, not hidden inside a single item line. The person who loads the container cannot see the email where you explained the mix. Write the mix on the quotation itself.
