What the 18 September notice actually says

China's trade-remedy information network reported on 18 September 2026 that Indonesia's investigating authority had made a final safeguard recommendation for imported tarpaulins made from polyethylene (PE). The recommendation is 13,400 Indonesian rupiah per tonne in year one, 12,391 in year two and 11,458 in year three. The notice identifies Indonesian tariff lines ex 3921.90.70 and ex 3926.90.99 and says the investigation covered 2021–2024 imports.

The same notice says the measure will be implemented only through an Indonesian Ministry of Finance levy order. That means a final recommendation and a legally collectible duty are different events. It also records a seven-day window for interested parties to request consultations after the notice.

Do not treat the recommendation as an immediate import ban

A safeguard measure is a temporary trade remedy intended to address serious injury or a threat of serious injury from increased imports. The WTO description of Indonesia's 2024 initiation explains that interested importers and exporters may present evidence during an investigation and that a safeguard action requires the relevant finding; it is not a blanket prohibition on every plastic sheet or every shipment from China.

For a live quotation, ask the Indonesian importer or customs broker whether a Ministry of Finance order has been published, its effective date, the exact tariff-line wording, any country or product exclusions, and how the levy is calculated. Until those points are confirmed from the current Indonesian instrument, show the possible levy as a separate risk item rather than silently adding it to the price.

Turn the product scope into RFQ fields

Describe the tarpaulin by material and construction, not only by a trading name: polyethylene grade, woven or laminated structure, fabric or film layers, coating, thickness, dimensions, weight per square metre, colour, eyelets, edge treatment and intended use. Ask the supplier to provide technical data and photographs that match the goods to be shipped. The tariff classification should be reviewed by the destination broker against the actual construction, because an ex code does not by itself prove that every similar-looking product is covered.

For each quote, record the proposed HS or Indonesian tariff line, origin, exporter, manufacturer, Incoterm, customs value basis, shipment date and whether the price includes or excludes any safeguard levy. Keep the product drawing, bill of materials, sample approval and classification opinion together so a later reclassification does not become a dispute between buyer, supplier and forwarder.

Protect the purchase order and cash plan

If the Indonesian finance order is still pending, write a change-in-duty clause into the purchase contract. It should state who confirms the final rate, who pays an import-side levy, whether the buyer may delay or cancel before loading, and how the parties handle a change after the commercial invoice is issued. Do not promise a fixed landed cost to the end customer without a dated broker calculation.

For goods already in production, ask the importer to obtain a written broker view before packing. Compare the cost of waiting for the Indonesian order with the cost of storage, demurrage, financing and a new quotation. A small test shipment can still be exposed if its tariff line and origin fall inside the final instrument.

Release gate before loading

Record one of four decisions: outside the verified scope; potentially covered and awaiting the Indonesian levy order; covered with a confirmed landed-cost adjustment; or not suitable for this shipment. Recheck the official Indonesian customs and finance publications immediately before export clearance, because the CACS notice gives a recommendation rather than an implementation date.

This update was verified on 19 September 2026. It summarizes the cited official trade-remedy notices and is not customs, tax or legal advice. The importer and a qualified Indonesian broker should confirm the current order, tariff classification, exclusions and effective date for the actual product before any irrevocable payment or loading instruction.

Your next-order checklist

  • Separate the final recommendation from the Indonesian Ministry of Finance order that would make a levy collectible.
  • Describe polyethylene tarpaulin construction, dimensions, weight and accessories in the RFQ.
  • Ask the destination broker to confirm the exact Indonesian tariff line and any exclusions for the actual sample.
  • Show a possible safeguard levy separately and add a written change-in-duty clause before production.
  • Recheck the official Indonesian order and effective date immediately before clearance and loading.
