Shipping from the Xiamen warehouse: routes, weight and the parcel form

What one kilogram cost to seven countries

The estimator at uidbuy.com/estimation needs no login. Give it a country, a weight, a postcode and a category and it returns every line with its days, price and labels. The prices above were after a 40 per cent newcomer coupon; before it, the American EUB-1 line was $37.84 and the faster US Line Packet-1 $45.62 for the same kilogram. Its own FAQ says the final bill usually lands within 5 to 10 per cent of the estimate.

Germany, France and Poland each list a line whose name ends in KH-1 that only starts at 13 kg; it shows up in the list at 1 kg but is not a 1 kg option. In the United States one line quoted $355.15 for a kilogram, clearly built for a different kind of cargo. Open the UIDBuy estimator with your own country before trusting any figure here.

Two divisors for one box

Lines that bill on volume compare two figures, the box's volume turned into kilograms and the reading on the scale, and charge the bigger. Here UIDBuy is not consistent. The estimator FAQ divides centimetres cubed by 6000. The help article on actual and volumetric weight divides by 5000, and adds that some carriers work with 6000, 7000 or 8000 instead. A box of 45 × 32 × 12 cm comes to 2.88 kg at 6000 and 3.46 kg at 5000, so the difference is real money on a light, bulky parcel such as two hoodies and a puffer.

Two levers help. Ask the warehouse to remove shoe boxes and outer packaging when you submit the parcel; the estimated billing weight will change, and the help centre says so. And put soft items around hard ones rather than in their own box. The box and calendar tool runs both divisors side by side.

When one box beats two

One combined box means the opening weight block and the per-parcel handling charge are paid once rather than for every box. UIDBuy's example uses an EMS line with 205 yuan for the first 500 g and 72 yuan per further 500 g; the arithmetic in the article does not match its own total, so use the idea and not the number.

The same article gives a warning worth more than the example: customs in many countries judge a parcel's purpose by its weight and by how many of the same item it holds, and parcels over 10 kg are much more likely to be treated as commercial. Two parcels of 6 kg can cost less in duty than one of 12.

• Anything 90 cm or longer on any side is flagged to travel alone.
• Items with a mailing restriction limit the routes for the whole parcel.
• Buying several things from one seller in one checkout means one domestic freight charge instead of several.

Declaring a parcel: system or personalised mode

When you submit a parcel UIDBuy asks for a declaration mode, personalised or system, and a declared value. Its help article asks for a value that is neither too high nor too low and notes that under-declaring raises the chance of inspection. This site gives no advice on what to declare beyond that: the right figure is what you paid.

Two recent official notices concern this stage. On 21 October 2026 UIDBuy posted a notice about new EU customs rules, and on 20 October one about delivery delays in parts of Spain. Read both on the site before sending to an EU address; this page will not paraphrase rules that are still being announced.

Storage: 90 days for purchases, 60 for forwarding

Goods bought through UIDBuy get 90 free days on the Xiamen shelves, counted from the warehoused status. Parcels you had sent in yourself, the forwarding service, get 60. UIDBuy may then regard them as abandoned and destroy them, according to the help centre. The home page mentions only the 90 days, so the shorter forwarding period is easy to miss.

Ninety days is long enough to wait for the last item of a planned box. It is not long enough to forget about. Put the end date in your calendar when the first item lands.

Late parcels and the Deliver Late, Money Back label

Every route in the estimator replies of 22 October 2026 carried a label reading, in UIDBuy's words, delivery over 30 days, 20 per cent shipping back. It belongs to a campaign called Deliver Late, Money Back, which UIDBuy's activity feed shows as open since 22 July 2026. The help centre has a long policy on international delivery delays and on compensation for insured and uninsured parcels; if a parcel is lost, those are the articles to quote to support.

Tracking appears under Parcels once the box leaves Xiamen. A status reading that the plane entered the port is ambiguous by UIDBuy's own account: the parcel may still be moving, or it may have landed and be waiting for a local scan. Either way it is not yet out for delivery.
