China Ammonium Sulphate Export Inspection in 2026

Current status as of 22 October 2026. A buyer evaluating a Chinese ammonium sulphate offer now has an additional export step to account for. The relevant question is whether that step has been allowed for in this shipment, not whether the supplier can quote a nominal loading date.

This article covers China’s export-side inspection rule. It does not assess a buyer’s destination-country import requirements or the availability of any particular cargo.

Which ammonium sulphate products are covered?

General Administration of Customs Announcement No. 97 of 2026, dated 9 July and effective from 16 July 2026, added the export-inspection supervision condition “B” to two Chinese 10-digit customs codes. The annex identifies 3102210000 as ammonium sulphate, changing its condition from A to A/B. It identifies 3102290000 as double salts and mixtures of ammonium sulphate and ammonium nitrate, with B added.

The exact classification matters. A description such as “ammonium sulphate fertilizer” in an offer is not, by itself, a confirmation of the 10-digit code to be used for the proposed goods. The exporter or its customs adviser should confirm the classification against the actual product before the buyer treats the quotation as export-ready.

This is a specific 2026 addition. The annex to GACC Announcement No. 81 of 2021 listed 29 fertilizer-related codes for export inspection, but did not list these two ammonium sulphate codes. The two notices should not be compressed into a claim that every fertilizer acquired the same requirement on the same date.

What does statutory export inspection mean?

For goods covered by the mandatory inspection catalogue, inspection is a legal step in the Chinese export process. Article 5 of China’s Import and Export Commodity Inspection Law states that goods subject to mandatory export inspection may not be exported without passing it, unless an exemption has been approved under the law.

The GACC service guide for statutory commodity inspection describes an application by the consignor, consignee or agent, followed by customs review and inspection where required. It says the decision on an on-site examination or sampling depends on the applicable rules, the enterprise’s credit standing and product risk. The guide does not give one completion period for all products and cases. It expressly notes that different goods and test items have different inspection periods.

For a buyer, that means a seller’s estimated loading date should be supported by the status of the particular goods and application. The announcement alone cannot tell you how many days this shipment will take.

Customs inspection is separate from a buyer’s quality inspection

A producer’s certificate of analysis, a sample tested by a private laboratory and a buyer-appointed pre-shipment inspection can help assess contract quality. They do not, on their own, establish that China Customs has completed the statutory export inspection for the proposed shipment. Conversely, a completed customs step would not replace the buyer’s own contractual specification and acceptance arrangements.

The distinction matters when a supplier says the material is “already inspected.” Ask which inspection they mean, who performed it, what goods it covered and what stage of the Chinese export procedure remains. Our pre-shipment inspection guide deals with the separate buyer-controlled quality and loading checks.

How to assess a proposed shipment date

No public notice can confirm an individual supplier’s cargo or vessel. The following sequence is a commercial screening tool for the buyer, not a prescribed customs form. A seller should be able to explain each point in writing without sending sensitive transaction files through a public website.

Decision stage	What the buyer should establish	What remains uncertain if it is missing
Comparing offers	The actual product, proposed Chinese 10-digit code and company responsible for export declaration	Whether the quoted goods and exporter fall under the stated procedure
Agreeing a loading period	Whether the goods are ready, who is handling the inspection application and which steps are still pending	Whether the loading date includes enough time for this shipment’s outstanding work
Treating shipment as executable	The transaction-specific inspection and customs status, plus the relationship between the inspected goods and the goods to be loaded	Whether a general claim about capacity or a past shipment applies to this order

The buyer can use these answers to decide whether a firm delivery commitment is justified or whether the quotation still depends on unresolved conditions. For specifications, packing and destination checks, use the separate ammonium sulphate sourcing guide. For the expected commercial document package, see the fertilizer import documents guide.

What the 2026 notice does not establish

Announcement No. 97 changes inspection coverage for the two codes. It does not announce an ammonium sulphate export quota, grant a particular company an allocation, publish a universal inspection turnaround time or confirm an individual cargo for loading. Those are different questions and need different evidence.

Nor should a buyer assume that the words “customs inspection required” mean exports are banned. The official rule establishes an inspection requirement. Whether a proposed shipment can proceed depends on its classification, the applicable procedure, its result and other transaction-specific conditions.

Our review found the notice and the general customs service guide, but not public proof of any named exporter’s current inspection outcome. The GACC original announcement page was not consistently accessible during this review, so the linked notice and annex are the GACC text reproduced by Hong Kong’s Trade and Industry Department. We checked the linked rule and customs guide on 22 October 2026; the position should be reviewed again if a later customs notice changes it.

Next step for an importer

Before relying on a Chinese ammonium sulphate loading date, get a clear answer on the product code, export entity and unfinished inspection steps. If you want FertiAxis China to assess a defined sourcing requirement, send your company, product, quantity and destination. We can then discuss the specification and proposed shipment period with you directly.

This is general procurement information, not a transaction-specific customs determination or confirmation that a seller’s cargo can be exported. Sources were reviewed on 22 October 2026. The next planned rule review is 20 January 2027, or earlier if a relevant customs notice changes.
