“Commercial inspection” refers to statutory inspection; only export goods listed in the statutory inspection catalog require a declaration for inspection, and those that are uninspected or fail inspection are prohibited from export. Whether hardware structural components require statutory inspection depends on one factor: the regulatory conditions associated with your product’s HS code.
This article outlines the method for determination, the operational process, and common misconceptions.
I.
How to determine if statutory inspection is required
Simply check the customs regulatory conditions for the product’s HS code: if the regulatory condition includes the letter **”B”**, statutory inspection is mandatory for export; if there is no “B,” statutory inspection is not required, and you may proceed directly to customs declaration.
Hardware structural components generally fall under Chapter 73 (Articles of Iron or Steel): most ordinary fasteners, stamped parts, and machined parts have no specific regulatory conditions and can be declared directly. However, there are two exceptions: first, the export of **hazardous chemicals** (items listed in the *Catalog of Hazardous Chemicals* are subject to statutory inspection; Customs adds a 3-digit regulatory identification code to the HS code to link inspection requirements, and failure to apply for inspection will result in administrative penalties); second, certain **iron and steel products** (such as steel plates, pipes, and sections) are subject to export license management starting January 1, 2026 (licenses are obtained by presenting the export contract and the manufacturer’s quality inspection certificate)—note that licensing and statutory inspection are distinct steps, both of which must be handled prior to export.
II.
Operational process for goods subject to statutory inspection
Following the integration of customs and inspection functions, the “Customs Clearance Form for Entry/Exit Goods” has been abolished. For goods subject to statutory inspection, data for both customs declaration and inspection application are submitted simultaneously via the **integrated declaration interface** on the “China International Trade Single Window.” Customs reviews the submission, conducts the inspection, and grants electronic release upon successful completion.
Key Requirement: Commodity inspection must be handled by the **original manufacturing factory** with the local Customs authority (the manufacturer must file the declaration; trading companies cannot do so on their behalf). The factory must first complete filing/registration with the local Customs;
an on-site factory inspection may occur during the initial process, and documents such as contracts, invoices, and packing lists must be uploaded during declaration.
For certain product categories, inspection and quarantine procedures have shifted to an “enterprise-based” supervision model, moving away from batch-by-batch inspection; eligible enterprises enjoy faster customs clearance.
III. Three Things Not to Confuse
First, **Statutory Inspection (Commodity Inspection) ≠ Third-Party Testing**: The former is mandatory regulatory oversight by Customs, while the latter (e.g., reports from SGS) is a requirement of the customer or the destination country; both may be necessary for export. Second, **Export License ≠ Commodity Inspection**: Licenses govern quotas and products on the control list (including certain steel products added in 2026), whereas commodity inspection covers mandatory statutory checks; HS codes must be verified separately for each. Third, **Dangerous Goods Packaging Assessment**: Exporting dangerous goods requires not only hazardous chemical inspection but also packaging assessment (performance testing plus usage assessment); a transport assessment report is also required for booking space, making this a distinct step in the process.

Practical Advice
When accepting an order, perform a “Three-Check” review: check HS code regulatory conditions (specifically for the “B” code requirement), check the export license catalog (43 types in 2026, including newly added steel products), and check for association codes linked to the hazardous chemicals catalog. If none of these apply, ordinary hardware items can be declared under standard general trade procedures. If they do apply, handle the relevant formalities in advance and allow sufficient time (factory inspections, testing, and certificate issuance all take time).
Industry experts warn that the biggest pitfall regarding commodity inspection isn’t the question of *whether* to do it, but the error of *declaring without checking*—specifically, misclassifying HS codes and failing to declare items subject to statutory inspection. This is a common risk point in export customs clearance;
always consult a customs broker or use the Customs pre-classification service to confirm the correct classification.
