When a seller asks "what are your lane parameters for the US, the UK or the EU?", the useful answer is not a single rate card. It is the set of parameters that determine how an individual order moves from a China warehouse to the buyer's door: which site receives and releases the order, how chargeable weight is calculated, which factors set the transit estimate, what type of carrier handles the last mile, and which product categories need a compliance check first. This page lists those parameters for the three destination lines FulfillNexa by SBT plans most often — the United States, the United Kingdom and the European Union — as of 2026.
Two ground rules apply to every parameter on this page. First, FulfillNexa by SBT does not publish rates: pricing is shipment-specific, so this page states the structure of a lane quote rather than numbers that would be wrong next week. Second, transit estimates are quoted per lane and confirmed in writing before dispatch — the ranges below are published industry references, not a FulfillNexa commitment.
Parameter 1 — Which warehouse handles the order
All three destination lines start from the same three China sites, confirmed at 24,000 m² of combined operating space. The receiving warehouse depends on the cargo profile and supplier location, and it is confirmed before dispatch:
| Warehouse | Size | Role on the small-parcel lanes |
|---|---|---|
| Dongguan | 8,000 m² | Ecommerce warehousing and one-piece fulfillment for apparel, toys and similar ranges — the default release site for individual US/UK/EU orders. |
| Suzhou | 13,000 m² | East China consolidation and fulfillment support for Yangtze River Delta suppliers before parcel release. |
| Shenzhen | 3,000 m² | Distribution and transshipment center near the airport corridor — oversized cargo and sea–air / air–sea movements rather than standard parcel release. |
For a one-piece dropshipping order to a US or UK address, the working pattern is: suppliers (or a Suzhou consolidation run) feed Dongguan, and the parcel is released through a cross-border channel matched to the destination. Shenzhen enters the picture when the same brand also moves oversized goods or uses sea–air / air–sea combinations — those loads transit the Shenzhen operation instead of the parcel flow.
Parameter 2 — Chargeable weight and the volumetric divisor
Chargeable weight is the number the lane price is built on, and it is calculated the same way for US, UK and EU parcel lanes:
- Volumetric weight (air) = length × width × height (cm) ÷ 6000. The 6000 divisor is the general IATA rule for air cargo volumetric rates; IATA's own guidance states the rule as volume in cubic centimeters divided by 6000, with the higher of actual and volumetric weight charged.
- Actual weight = the packed weight on the scale, including product, retail packaging and any outer polybag or carton.
- Chargeable weight = the higher of the two. A 40 × 30 × 20 cm parcel of pillows weighing 1.2 kg has a volumetric weight of 4.0 kg (24,000 ÷ 6000), so it bills at 4.0 kg even though the scale shows less.
- Some express-type products use a different divisor (commonly 5000). The applicable divisor is a property of the selected channel, so the quote states which divisor and which formula were used.
Worked example (illustrative, not a rate): a 2 kg order packed at 30 × 24 × 18 cm → volumetric = 12,960 ÷ 6000 = 2.16 kg → chargeable 2.16 kg. The same order repacked into a 35 × 30 × 25 cm box → volumetric = 26,250 ÷ 6000 = 4.375 kg → chargeable 4.375 kg. Same product, same destination, nearly double the billed weight — packaging choices are a lane parameter you control.
Parameter 3 — Transit-time structure
A lane transit estimate has a defined start point and several influence factors, and the estimate is only meaningful when both are stated:
| Factor | What it changes |
|---|---|
| Estimate start point | Order release, warehouse dispatch, or carrier acceptance scan — confirm which one the quote uses. |
| Channel type | Dedicated e-commerce air lines, postal products and express products differ in both speed and clearance handling. |
| Customs stage | US formal/informal entry treatment, UK import VAT and CDS declarations, and EU IOSS/VAT flows each add a different step. |
| Peak periods | Q4 volume and carrier capacity cuts can extend published estimates. |
| Final-mile leg | Remote-area surcharge zones and carrier delivery schedules affect the last day, not the international leg. |
Published industry reference ranges (2026, per carrier-published standards — verify against the carrier page before relying on them): US-bound dedicated air parcel lines commonly quote multi-day door-to-door estimates measured from dispatch; UK-bound lines are similar in structure with Royal Mail or a contracted carrier on the final mile; EU-bound lines vary more because the final-mile carrier and the customs treatment differ by country. The lane quote FulfillNexa by SBT issues states the channel, the start point and a dated estimate for the specific destination postcode — that written estimate, not a generic table, is the operational number.
Parameter 4 — Last-mile carrier types
The international leg ends at a destination hub; a domestic carrier network completes delivery. The typical final-mile carrier types per line:
| Lane | Typical final-mile carrier types |
|---|---|
| US | USPS (postal injection or Ground Advantage products) and UPS/FedEx-type networks for express-type channels |
| UK | Royal Mail for postal-type channels; Evri/DPD-type networks for contracted courier channels |
| EU | Country-specific networks — DPD, GLS, DHL-type and national postal operators depending on destination country |
Which carrier actually delivers depends on the channel selected for the order. If the buyer experience depends on a specific final-mile carrier (for example, PO Box delivery via USPS), state that requirement when requesting the quote so the channel can be matched to it.
Parameter 5 — Product-category boundaries
Acceptance is product-specific, and a few categories drive most of the pre-checks:
- Apparel and toys are core categories at the Dongguan one-piece operation; toy listings for the US should already account for CPSIA requirements (see the toy fulfillment compliance guide).
- Battery-containing and lithium products move only through channels with the corresponding acceptance and documentation (see the lithium battery air shipping SOP).
- Cosmetics need ingredient and destination-rule review before the first order ships (see the beauty & cosmetics fulfillment guide).
- Oversized or high-value pieces do not travel on the standard parcel flow — they are assessed through the Shenzhen transshipment operation (oversized cargo guide).
Parameter 6 — What a lane quote contains
Because pricing is shipment-specific, the lane quote is the operative document. Every quote should itemize:
- Freight for the selected channel, priced on the stated chargeable-weight rule and divisor.
- Warehouse handling (receiving, pick, pack, agreed inserts or packaging).
- Export documentation and any clearance-related charges at destination.
- Final-mile delivery, including remote-area surcharges where the postcode requires them.
- The dated transit estimate with its start point, and the tracking scope the channel supports.
Asking four providers for quotes on the same SKU, packed dimensions and destination postcodes is the fastest way to see which parameters actually differ between them.
FAQ
Does a lower volumetric divisor always mean a cheaper lane?
No. The divisor changes how dimensions convert to billed weight, but the per-kilogram rate differs per channel. A channel with a 5000 divisor and a lower rate can still bill more than a 6000-divisor channel for a bulky parcel. Compare the final quoted total on the same example parcel, not the divisor alone.
Can one order split across two lanes?
Yes, and sometimes it should. If a restock includes both standard apparel and a battery-powered item, the standard items can ship on the normal parcel lane while the battery item waits for a compliant channel. Splitting is decided per order against acceptance rules, not automatically.
Which warehouse should inventory be sent to for US orders?
For typical one-piece US-bound ranges, Dongguan is the working release site and Suzhou supports East China supplier consolidation before release. Shenzhen handles oversized and sea–air / air–sea movements. Send the SKU list and cargo profile first so the receiving site is confirmed against the actual plan rather than assumed.
Why is there no price table on this page?
Lane pricing depends on chargeable weight, channel availability, destination postcode and the agreed service scope at the time of booking. Published flat tables go stale quickly and cannot represent a specific shipment, so the quote — itemized as in Parameter 6 — is the source of truth. The small-parcel cost guide explains the cost components in more depth.
How do I compare two lane quotes fairly?
Feed both quotes the same inputs: identical cargo profile, weight tier, destination postcode and service scope, then compare line by line against the six parameters above. A quote that is silent on the volumetric divisor or the last-mile carrier type is not comparable — it is incomplete. The provider comparison guide applies the same method across four fulfillment models.
