Shipping about 100 kg from China to the USA? Prepare final carton data, compare route scope, align import documents, and review each quote with five checks.
Shipping about 100 kg from China to the USA should be quoted as a defined shipment, not as “100 kg” alone. Before comparing providers, confirm the final cartons, product details, US ZIP code, delivery requirements, customs responsibility and the date the goods must be available. Without those details, a price is only a planning estimate.
This page is for small importers, online sellers and buyers preparing a medium-size shipment. Its purpose is practical: help you send the same quote brief to each provider, compare like with like and choose a route without repeating the general theory of international shipping prices.

First decide what the 100 kg represents
Write down whether 100 kg is:
- the supplier's product or net weight;
- the combined domestic parcel weight received by the China warehouse; or
- the final gross weight after consolidation, protection and export packing.
These are not interchangeable. The quote should be confirmed from the final number of cartons and the measured outer dimensions of each carton. If the goods have not reached the warehouse, label the result as provisional and ask what information can still change it.
For the separate explanation of actual, dimensional and chargeable weight, read why a China shipping quote changes after packing. This article uses those measurements as inputs instead of repeating the calculation lesson.
Build one quote brief for every provider
Send every provider the same data set:
- Cartons: quantity, outer length, width, height and gross weight for every carton.
- Products: precise names, materials, quantities, intended use and declared values.
- Route-review details: batteries, liquids, powders, magnets, fragile items, branded goods or other characteristics that may limit eligible services.
- US destination: ZIP code, city, residential or commercial address, loading access and any appointment or liftgate requirement.
- Inventory deadline: the date the goods must be available, not merely the preferred departure date.
- Import arrangement: the intended importer, broker or carrier-clearance arrangement and who pays duties, taxes and destination charges.
- Packing rules: retail boxes, labels, seals, serial numbers or protective inserts that must remain.
Do not accept a final quote based only on total kilograms. UPS also advises shippers to enter accurate package dimensions because dimensional weight and handling conditions can affect billing. Review the current carrier guidance for the selected service rather than applying one divisor or limit to every route: UPS package dimensions and weight guidance.
Choose a route by the job it must do
Ask for eligible options only after the product review and destination are known.
Urgent replenishment
Request an express or air-based option when the inventory deadline justifies it. Compare the complete door-to-door plan, including warehouse preparation, export handling, import clearance and final delivery. A line-haul estimate is not the same as the date the cartons will be available at the US address.
Flexible replenishment
Ask for slower freight options when the deadline allows. Confirm minimum charges, origin and destination handling, delivery scope and whether the service fits the carton count and product type. A lower transport rate is not useful if important destination costs are excluded.
Mixed urgency
If only some SKUs are urgent, compare one combined shipment with a split plan. Splitting may protect an inventory deadline, but it can also create another packing job, minimum charge, customs file and delivery charge. Treat it as a service decision, not an automatic saving.
Compare scope before comparing price
For each option, request one written total and mark every item as included, excluded or still unknown:
- China pickup or supplier delivery to the warehouse;
- receiving, consolidation, repacking, cartons, reinforcement or pallet work;
- final actual and chargeable weight and the rule used;
- export handling and international transport;
- import clearance, duties and taxes;
- destination terminal, residential, remote-area, appointment or liftgate charges;
- final-mile delivery to the named ZIP code;
- optional insurance or declared-value protection and its exclusions;
- quote validity and the event that starts the transit estimate.
Use the DDP and DAP guide for small US importers to clarify responsibility. “Door to door” or “tax included” is not enough by itself; the written quote should identify the importer arrangement, named destination and any charges still payable after arrival.
Approve packing without damaging the goods
Right-sizing cartons can reduce avoidable space, but the instruction must protect the product and its resale value. Tell the warehouse what may be removed and what must remain. Keep required retail packaging, barcodes, seals, manuals, serial labels and protective inserts unless you approve a specific change.
For item-level instructions, use the custom packaging guide for shipments from China. If several suppliers are involved, use the US consolidation checklist to match every arrival, SKU and carton before dispatch.
Prepare the US import file before dispatch
The shipment data and customs documents must describe the same goods. At minimum, align the commercial invoice, packing list and carton marks with the actual products, quantities and values. US Customs and Border Protection states that commercial-invoice information should include an adequate merchandise description, quantities, values and the relevant tariff classification. Product-specific agencies or permits may also apply.
Check the current official guidance before shipping:
If the importer, classification or product requirements are unclear, resolve them with the carrier, licensed customs broker or appropriate authority before authorizing dispatch.
Five checks before accepting the quote
Do not treat the quote as ready until you can answer yes to all five questions:
- Is it based on the final cartons or clearly marked as provisional?
- Does it show the chargeable weight and the rule used?
- Are the origin, international, customs and US delivery scopes separated clearly?
- Are product restrictions, importer responsibility and required documents resolved?
- Does it state validity, estimated delivery basis and what can change the total?
If one answer is no, request a revised written quote. This is more useful than negotiating a lower rate against incomplete shipment data.
