Shipping 21KG from China to United States comes to roughly USD 76 at the published rate of USD 3.61 per kg. Treat that as a planning estimate for the freight: the commodity, its HS code, the packed dimensions and the exchange rate on the day all move it, and duty through U.S. Customs and Border Protection (CBP) is quoted separately. The real figure can land above or below.

Indicative published rates for planning, not a quotation. Actual cost depends on the product and its HS code, chargeable weight, declared value, duty and tax at destination, and the exchange rate on the day.
How these prices are calculated — chargeable weight
Freight is not billed on the number on your bathroom scale. It is billed on chargeable weight: the greater of actual gross weight and volumetric weight, where volumetric weight is L × W × H (cm) ÷ 6000. Denser cargo pays on its weight; light bulky cargo pays on the space it occupies. Whichever is higher is the one you pay — never the lower.
One cubic metre = 167 kg. That is 1,000,000 cm³ ÷ 6000, the same divisor used for the volumetric check, so both sides of this page agree with each other.
Per-kilogram channels. The rate is multiplied by chargeable weight, rounded up to the next whole kilogram. A 21 kg consignment that only measures out to a smaller volumetric figure is still charged on its 21 kg actual weight.
Freight only. These are published freight rates. Duty, tax and customs charges at destination are not a fixed number we can print: they follow your product's HS code, its declared value and the exchange rate applied on the day of entry, so they are confirmed against your actual goods and quoted separately.
Indicative only — the real price can be higher or lower. Nothing on this page is a quotation or a commitment. What you finally pay depends on what the product is, how it is packed, the chargeable weight, the declared value, the destination duty position and the exchange rate at the time. Send the product details, weight and dimensions and we will price your specific shipment.

E-Commerce Restock
Small-Batch E-Commerce Restock
The 21 KG band is the classic e-commerce restock or first trial run. Air is the default — it lands the best cost-to-speed trade-off, and most managed air channels open at around 21 KG. Functionally this is less-than-container air freight.
Most managed air channels set their floor near 21 KG

What Sits Inside the United States Rate — and What Does Not
A freight rate is a scope, not just a number. Two quotes for the same lane can differ by a third and
still describe the same shipment, because one of them stops at the port and the other reaches the door.
Here is where the line falls on the figures published above.
Inside the published rate
Main carriage — the flight or the sailing itself
Origin handling: pickup in South China, consolidation, export declaration
Standard documentation for the lane
Quoted alongside, against your goods
Import duty and tax — a function of HS code and declared value, not of weight
Customs examination, where the entry is selected for inspection
Storage once free time at destination runs out
Remote-area delivery beyond the standard service map
When you compare us against another quote, compare the scope first. Ask what the number stops at, whether
duty is inside it or beside it, and who pays the destination terminal. The rate that looks cheapest on
an email is frequently the one with the most left out of it.
What Affects the Shipping Cost to United States?
Chargeable weight — you pay on actual or volumetric weight, whichever is greater (L×W×H ÷ 6000 for air)
Commodity surcharges — batteries, liquids and branded goods all attract extra handling fees
Seasonal peaks — Chinese New Year (Jan/Feb) and Golden Week (Oct) typically add 15–30% to rates
Delivery zone — parts of United States carry remote-area surcharges by postal code
Customs basis — import duty is assessed on the CIF value of the goods
Customs & Documentation for United States
De-minimis — consignments under the local threshold can clear free of duty
Paperwork — a commercial invoice, packing list and correct HS codes are the baseline
Managed clearance — RateHive can coordinate the customs entry and import-tax processing on your behalf
Restricted goods — batteries and liquids need supplementary certification
Food, supplements and certain health products need FDA Prior Notice
What does it cost to ship from China to United States?
On the current feed, China-to-United States rates open at USD 3.61/KG via LA OA – Parcel Delivery. For a 21 KG load that works out to a freight total of approximately USD 76. RateHive can manage the customs entry and import-tax step, while the duty itself follows the No federal VAT; duties vary by HTS code (often 0–6.5% for general goods) set by U.S. Customs and Border Protection (CBP).
What import duty and tax will I pay bringing goods into United States?
Entries into United States are assessed by U.S. Customs and Border Protection (CBP), and the regime that applies is: No federal VAT; duties vary by HTS code (often 0–6.5% for general goods). On de-minimis, the position is USD 800. RateHive offers managed clearance and tax processing — a coordination service, not Incoterms DDP — to handle these formalities for you.
Which gateways are used for China shipments into United States?
Ocean cargo into United States generally moves through Los Angeles/Long Beach, New York/Newark, Savannah; air clears via LAX (Los Angeles), ORD (Chicago), JFK (New York). We route through whichever gateway gives the fastest onward leg to your delivery address, with clearance handled as a managed service.
What currency are United States rates quoted and settled in?
We quote and invoice freight in USD; the destination-side currency in United States is USD. Payment usually falls due before departure (T/T or PayPal), and with managed clearance you settle the landed cost once rather than facing collect charges on arrival.
Which certifications does United States require on imports?
For regulated cargo into United States, budget for: FCC for radio devices; FDA Prior Notice for food/supplements. A missing conformity document is the single most common reason U.S. Customs and Border Protection (CBP) puts a shipment on hold, so verify your HS-code requirements before the goods leave China.
How is chargeable weight worked out for United States?
We take the greater of actual gross weight and volumetric weight (L×W×H ÷ 6000 for air), rounded up to the next kilo. One cubic metre therefore counts as about 167 kg. A 300 kg consignment that measures out to only 200 kg volumetric is still charged on the 300 kg — the higher of the two always wins. For 21 KG this bites hardest on light-but-bulky cargo, so re-packing or consolidating cartons can pull you into a cheaper band.
What's the best channel for 21 KG into United States?
At 21 KG into United States, Air Freight is the call — it strikes the best speed-to-cost balance (5–10 business days) at this size and clears through LAX (Los Angeles), ORD (Chicago), JFK (New York). Ocean minimums make sea uneconomical below about 50 KG.
How long is transit from China to United States?
Reckon on these door-to-door windows into United States: air 5–10 business days, ocean LCL 30–50 days, ocean FCL 28–45 days. Add roughly 2–5 days for clearance and dwell at the gateway, which RateHive can manage end to end.
