Cambridge China Bridge — China sourcing

Find the UK commodity code and import duty rate for a product from China, from a product description (English or Chinese) or a commodity code. Also flags codes where China-specific anti-dumping or countervailing duty exists.

Estimate customs value, UK import duty, import VAT and the total for goods imported from China, with the same arithmetic as the site's import duty calculator.

Estimate CBM, shipment weight and volume-only 20ft/40ft/high-cube container counts from one carton line. Useful for full-container RFQ planning; not a loading simulation or a freight quote.

Check whether a UK anti-dumping or countervailing measure applies to goods from China on a commodity code, from the live UK Trade Tariff. Deliberately gives no rate, because it depends on the exporter.

List the UK regulatory regimes (UKCA, WEEE, PSTI, toy safety, food contact, REACH, packaging EPR and others) that apply to a type of product imported from China, with what to ask the supplier for. Call with no product_type to list the product types.

Search Cambridge China Bridge's guides to importing from China to the UK (duty and VAT, shipping, Incoterms, suppliers, quality, compliance, sectors). Returns each guide's one-sentence answer and URL.

For a destination country, say what actually decides whether an import from China can happen there: a standards regulator, a bank through exchange control, a local trade licence, the tax authority, a risk-based check at import, or the buyer's own choice of where conformity is checked. Also says whether a missed requirement can be put right on arrival. Returns status not-verified, with no guess, for countries Cambridge China Bridge has not researched from primary sources. Call with no country to list the researched markets.

  "properties": {

      "type": "string",
      "description": "Destination country name in English or Chinese, or its two-letter code. Omit to list the researched markets."
    }

Work backwards from the date stock is needed to the date a China order must be placed, against the real Chinese New Year factory shutdown rather than the statutory holiday. Says whether the plan collides with the closure, and gives the latest order date that avoids it.

Compare air and sea freight on total landed cost rather than on the freight quote: includes duty charged on the freight itself, the cost of capital tied up in transit, and profit lost while stock is unavailable. Also returns the weekly lost profit at which the two routes cost the same.

Send the user's sourcing enquiry or quote request to Cambridge China Bridge by email; they reply to the user directly. Only call this when the user has asked to contact them, after showing the user exactly what will be sent and getting their agreement.
