Calculators, charts and comparisons for buying from Taobao, 1688 and Weidian. All free, no signup.

Ordering through a shopping agent involves four decisions that have nothing to do with picking the product: what size to order, what to declare at customs, which agent to fund, and which shipping line to put the parcel on. Each of them costs real money when you get it wrong — a wrong size means an international return, a careless declaration means duty or a held parcel, and the wrong line can double the cost of a heavy haul.
These tools exist to make those four decisions in a couple of minutes each, using numbers that carry a date rather than marketing claims. Nothing here needs an account, and nothing is gated. They sit alongside the main index of 8,600+ Taobao, 1688 and Weidian listings across 11 categories and 43 brands.
If you are new to this, the sensible order is: read the ZentBuy verdict to decide whether to use an agent at all, then the agent comparison to pick one, then the size chart before you order and the duty calculator before you ship.
Enter a declared value in CNY, pick a product category and a destination, and get duty, VAT or GST and the total landed cost. It checks your country's de minimis threshold first, because that single number decides whether the rest of the bill exists at all. Covers the US, UK, Germany, France, the Netherlands, Poland, Australia, Canada and New Zealand, and the page carries the duty-free thresholds for eleven countries as a table.
CN to US, EU and UK conversion for shoes and for men's and women's clothing, with foot length in centimetres and chest and bust measurements. Chinese sizing runs narrower than Western sizing at the same letter, so the tables are the baseline and the seller's own measurement image is the tie-breaker. The page also explains how to use QC photos of the size label to catch a mistake before the parcel leaves China.
The canonical dated table for this site: service fee, QC photo policy, shipping lines, free storage and minimum order for ZentBuy and eight competitors, with "Not published" wherever a figure could not be confirmed from an agent's own pages. ZentBuy's "0% markup" on the item price is listed as the agent's own claim, and the page explains why a 0% fee is not the same as a lower total cost once shipping and payment processing are added.
An honest assessment rather than a sales page: how the warehouse-and-QC model actually lowers your risk, what the "0% markup" claim does and does not cover, what ZentBuy does not publish (company history, a shipping rate card), the failure modes users of any agent report, and the concrete things that reduce your exposure on a first order.
43 brands mapped across the index, each with its own page. Sellers routinely disguise brand names in listing titles — "NK Style", "AD Style", "B Style", "CP Style" — so each brand page also matches the common abbreviations instead of only the literal name.
14 guides covering the whole order lifecycle: shipping lines and per-kilo costs, customs declarations by country, coupons, reading QC photos, payment methods and their buyer protection, and platform comparisons. Every guide carries a named author and a real review date, and the date only moves when the text changes.
How this index compares with community find lists, Discord feeds and rival agent databases — listed by type rather than ranked, since a self-ranked list from the site that owns one of the entries is not worth much. Useful if you are already funded on a different agent.
