A supplier quotation is only one part of wallpaper glue import cost. A 20kg bulk route supports local repacking or B2B supply, while 200g–1kg OEM packs reduce local processing but add packaging and loading complexity. Importers need one consistent model instead of comparing factory price per ton alone.
Choose one comparison unit
Calculate by kilogram of powder, retail pack or saleable unit, but keep one primary unit across the model. Convert 20kg bulk into the expected number of accepted local packs. For OEM packs, include cartons and the actual units per carton. Mixing units can make a low quote appear attractive only because downstream work is missing.
Separate pre-shipment cost elements
List powder, inner and outer packaging, print setup, samples, retail cartons, export cartons, pallets, labels and any additional document work. Do not assume every item is included in the product price. MOQ and artwork versions influence cost, but project amounts must come from the current quotation and approved pack specification.
Add logistics and import costs
Include China inland transport, forwarder handling, origin charges, ocean or air freight, insurance, destination charges, duty and tax, customs service and delivery to warehouse. Palletized versus floor-loaded and full-container versus LCL routes use space differently, so one freight-per-ton assumption is not reliable. The importer or qualified broker should confirm classification and tax.
Capture local repacking and loss
The 20kg route also needs labor, equipment, film, labels, cartons, line clearance, QC samples, remainder, loss, rework and local compliance management. Finished OEM packs carry higher finished-goods inventory and artwork-version risk. Both routes need an actual loss field rather than assuming every kilogram becomes saleable stock.
Decide with scenarios, not one number
Model at least a trial order, normal replenishment and slower-than-expected sales. Compare cash commitment, landed cost per saleable unit, inventory turns and channel margin. Hangzhou Karn can quote 20kg and OEM supply conditions separately; final landed cost depends on the buyer’s logistics, taxes, repacking and sales structure.
