Publication date is not the implementation date

China’s Ministry of Commerce and General Administration of Customs issued Announcement No. 50 of 2026 on 19 October 2026. The notice says it takes effect on 18 November 2026, and that the Dual-Use Items Export Control List will be updated at the same time. A buyer placing an order before 18 November should not assume that a later export will be outside the rules: check the planned export date and the exact item with the exporter.

This is an export-control notice for specified items leaving China, not a blanket ban on construction machinery and not an import rule for Taiwan, Indonesia or African destinations. The notice distinguishes exports to specified sensitive destinations, which require a licence from China’s commerce authority, from exports to other destinations, for which the operator obtains export proof through information registration. Destination-country import permits, customs duties and technical approvals remain separate checks.

Which equipment and parameters are listed

The notice lists full-face tunnel-boring machines, including earth-pressure-balance and slurry-balance shields and rock tunnel-boring machines, under control category 2B906. It also lists parts specially designed for those machines—cutter heads, screw conveyors, segment erectors, main-drive systems and other key units—and specified remanufacturing technology. The customs commodity numbers printed in the notice are reference numbers; do not use a tariff code alone to decide whether an item is controlled.

It separately covers walking excavators if any one stated capability threshold is exceeded: crossing a vertical obstacle higher than 1.2 m, wading deeper than 1.5 m, crossing a trench wider than 3 m, or climbing a slope steeper than 40 degrees. A high-altitude wet-shotcrete machine is listed only for use above 3,000 m and if all five conditions apply: engine maximum power above 75 kW and torque above 680 N·m; motor maximum power above 55 kW; pumping-system suction efficiency above 95%; air-compressor delivery above 15 m³/min; and hydraulic oil usable at −20°C. Check the complete notice against the actual model; do not infer coverage from a product label.

What the exporter must arrange

For exports to the sensitive destinations described in the notice, the export operator must apply for a licence under China’s export-control framework and may not export without it. For other destinations, the operator uses information registration to obtain export proof. The exporter and end user must also undertake not to transfer or provide the listed China-origin items to the specified sensitive destinations without permission. The notice also restricts such onward transfers by organizations and individuals outside China.

The exporter is responsible for accurate identification and truthful customs declaration. If an item is controlled, the declaration must identify it as a dual-use item and state its control-list code. If it is not controlled but its parameters, indicators or performance are close to a listed item, the notice requires the declaration remarks to say it is not controlled and provide the specific parameters. Customs may question incomplete, inaccurate or doubtful information and hold the goods while it checks.

A practical buyer checklist before deposit or booking

Ask the Chinese supplier for the exact manufacturer, model, configuration and technical data sheet—not just a marketing name. For a tunnel-boring machine or dedicated component, identify whether it is specially designed for a listed machine. For a walking excavator or high-altitude shotcrete unit, map each threshold to the manufacturer’s documented test data. Record the intended operating altitude, end user, final destination and any planned onward transfer accurately; the exporter may need those details for its classification and registration or licence process.

Before paying a balance or reserving transport, request written confirmation from the exporter of the item’s control assessment, the applicable licence or registration route, who supplies each document, and the earliest realistic export-ready date. Keep export-control paperwork separate from destination import certification, customs clearance and local delivery arrangements. The Chinese exporter handles its export declaration; the buyer should supply accurate end-use and destination information and separately confirm local import requirements with the importer or a qualified adviser. This is a procurement checklist, not a legal determination for a specific model or destination.

Your next-order checklist

  • Record the notice dates separately: issued 19 October 2026; effective 18 November 2026.
  • Match the exact model and configuration to the listed item descriptions; do not decide control status from a customs code alone.
  • For walking excavators, check all four capability tests and flag any one threshold that is exceeded.
  • For a listed high-altitude wet-shotcrete machine, verify use above 3,000 m and every one of the five technical conditions.
  • Give the exporter accurate end-user, end-use, destination and onward-transfer information before it begins the control process.
  • Obtain written confirmation of the exporter’s licence or registration route and export-proof timing before confirming shipment.
  • Separately verify destination-side import permits, duties, conformity rules and delivery; China export documents do not replace them.
