China Puts Working-Day Clocks on Dual-Use Customs Queries

China’s Ministry of Commerce and General Administration of Customs put a new timetable around customs queries on possible dual-use exports on 19 October. When an exporter presents no Ministry of Commerce licence and Customs has evidence that the goods may fall within the dual-use control perimeter, Customs must issue a written query. The exporter then has seven working days after receiving that notice to provide the required evidence. Customs has 15 working days after receiving all required materials either to complete its assessment or ask the ministry to organise identification; the ministry has a further 15 working days after receiving the complete identification materials. ^[1]

The rule gives exporters a more legible process for a border hold whose commercial cost can rise quickly. It also defines the limits of that predictability. Goods remain stopped while the query or identification is under way, time spent on supplementary materials and testing is excluded, and major or difficult cases can run beyond the stated clocks. ^[1]

The clock starts with an evidence file

The seven-day response is a documentation exercise. An exporter must provide the customs declaration, export contract, invoice and transport documents showing the goods’ flow. It must also explain the goods’ performance indicators and main use, set out the legal and factual basis for treating them as outside the control scope, and provide technical materials, including testing reports when available. Foreign-language material needs a Chinese translation, and the submission must carry the company seal. ^[1]

This procedural burden sits beside an existing classification duty. China’s dual-use regulation requires exporters to understand a proposed export’s performance indicators and principal use and determine whether it is a dual-use item. When they cannot determine the status, they may ask the Ministry of Commerce for a consultation. ^[2] The customs-query file therefore should be built from the same technical classification record that supports the company’s pre-shipment decision.

Two 15-day stages do not create a firm 30-day ceiling

The first 15-working-day stage belongs to Customs. It begins only after Customs has received all required exporter materials and ends either with a customs assessment or a request for the Ministry of Commerce to organise identification. If the case is referred, the second 15-working-day stage begins after the ministry receives the complete identification materials. Experts may be used, and testing may be sent to a relevant institution. ^[1]

Those stages should not be added together and presented as a guaranteed 30-working-day release date. Time used by the exporter to submit or supplement materials, and time used to test the queried goods, is not counted in the 15-working-day limits; major or difficult special cases fall outside the stated time limits. ^[1] The commercial inference is clear: the formal timetable improves visibility, but weak technical records can still extend inventory, logistics and contract exposure.

The announcement offers one practical containment tool. If unrelated goods share the same customs declaration with the queried goods, the exporter may ask to split them out. Customs can allow the separate clearance after an assessment. ^[1] This can isolate a disputed line item from the rest of a shipment, although the wording gives Customs an assessment role rather than an automatic release obligation.

The procedure follows goods across channels

The announcement applies by reference to exports through cross-border e-commerce, passenger carriage, mail and express delivery as well as conventional freight. During the query or identification period, the affected goods are not released. If Customs concludes that the item is outside the dual-use perimeter, clearance continues; if it is a dual-use item, the authorities handle it under the applicable control rules. ^[1]

That boundary matters because a customs query is separate from an export-licence review. China’s dual-use regulation establishes licensing for controlled items and separately authorises Customs to question unlicensed goods that may be controlled. It also places the initial classification duty on the exporter. ^[2] A favourable query result can resolve whether a particular shipment belongs inside the control perimeter; it does not create a general exemption for later shipments or altered specifications.

The new announcement took effect on publication and replaced the 2025 Customs notice on the same procedure. ^[1] Its operational message is to prepare for a classification challenge before goods reach the border. Exporters need version-controlled specifications, use cases, test evidence, Chinese translations and a named owner who can assemble the file within seven working days. Freight forwarders and sales teams then need a route for separating unrelated goods when a mixed declaration is held. The clocks make the process more measurable; the quality of the evidence will still determine how useful that measure becomes.
