China is the corridor on this site where documentation most reliably decides the outcome. The goods description on the invoice has to support the tariff classification, the consignee has to be the registered entity with the customs registration to receive, and the details on the paperwork have to match that registration exactly. A near match is a mismatch. None of this is unusual in principle; what is unusual is how consistently it is enforced.
Categories requiring a permit, a licence or a registration certificate need it in hand before the courier boards rather than applied for afterwards. Medical devices, cosmetics, certain foods, radio-equipped devices and controlled materials all fall into this, and a consignment that arrives without the certificate is a consignment that waits.
Export control cuts both ways on this corridor. A meaningful share of semiconductor, measurement and materials technology is controlled leaving the origin country, and a meaningful share of Chinese exports is licensed. We check both before quoting, because urgency does not change an export control position and finding out late does not make it faster.
The last recurring issue is valuation on non-sale movements. Samples, returns, failure-analysis pieces and demonstration units have a value even without a sale, and a proforma invoice with a defensible basis is what keeps them moving. Repair-and-return belongs under a temporary admission or processing regime rather than as an outright import in either direction.
