A product may fall outside China's export control thresholds and still face questions at customs. When its technical specifications are close to those of controlled goods, the export declaration matters as much as the product itself.
On 19 October 2026, Chinese authorities published several announcements updating export controls and customs procedures. Announcement No. 49, effective from 18 November, covers certain drone-related products, including brushless motors, electronic speed controllers and carbon-fibre propeller blades.
For example, the controlled category of brushless motors specially designed to drive drone propellers requires four characteristics together: rated voltage of at least 48 V, rated power of at least 3 kW, power density of at least 3 kW/kg, and rated speed not exceeding 3,000 rpm. A motor falling short of one criterion may be outside this particular category, but that does not necessarily remove the need to document its specifications.
The announcement also requires exporters to declare relevant technical parameters for goods with characteristics close to those of controlled items and state when the goods are not subject to export controls.
A separate regulation, Announcement No. 52, took effect on 19 October and sets out how customs handles suspected dual-use goods. Where customs has evidence that an unlicensed shipment may contain controlled items, it can withhold release and request supporting documents.
The exporter then has seven working days to submit the required materials, including customs declarations, contracts, invoices, transport documents, technical information and an explanation of the product's performance and intended use. Documents must be stamped, and foreign-language materials accompanied by Chinese translations.
Customs has 15 working days after receiving the complete documentation to reach a preliminary determination or refer the case to the Ministry of Commerce. The Ministry then has 15 working days after receiving complete materials to assess the item. Testing, supplementary documentation and exceptional cases can extend the process.
For European buyers consolidating goods from several Chinese manufacturers, this creates a particular risk. An item questioned by customs can delay unrelated products covered by the same export declaration. The regulation allows unaffected goods to be separated, but only with customs approval.
The practical response is to check technical specifications against the published controls before placing the order, obtain supporting documents from manufacturers, establish who is responsible for the Chinese export declaration, and consider separate declarations for potentially sensitive items.
At Berg, this is the kind of issue we aim to identify during procurement rather than after goods arrive at the port. Technical documentation, supplier coordination and export arrangements belong in the purchasing process, not as an afterthought.
