Did you know there are so many hidden pitfalls in import customs clearance? 90% of people make mistakes at the very first step

"Mr. Zhang recently purchased a batch of equipment overseas but got stuck in customs clearance for two weeks, incurring demurrage fees as high as $50,000..." Such stories are not uncommon in the import/export industry. General trade import customs clearance may seem like a simple process of "submitting documents and waiting for release," but it's actually full of complexities. This article will deconstruct the entire general trade import customs clearance process to help you avoid those costly "pitfalls."

Many importers assume customs clearance begins with filling out the declaration form, but 90% of issues stem from inadequate preliminary preparation:

• Product Classification: Incorrect HS codes can double tax rates. One company paid 60% more tariffs by misclassifying "stainless steel kitchenware" as "steel products."
• Document Review: Certificates of origin, quality inspection reports, and trademark authorization letters are essential. Ms. Li had an entire batch of luxury goods returned due to missing original manufacturer authorization.
• Trade Method: Choosing between general trade, processing trade, or temporary import directly affects subsequent tax refunds and regulatory requirements.

Here’s a standardized process summarized by Zhongshi Customs experts, worth bookmarking:

• Step 1: Bill of Exchange - Use the ocean bill of lading to obtain the delivery order (D/O) from the shipping company. Note that telex release bills require additional stamps.
• Step 2: Declaration - Submit 11 basic documents, including the customs declaration form, invoice, and packing list, via the Single Window system.
• Step 3: Inspection - About 30% of goods undergo manual inspection. Preparing a cargo location map in advance can shorten inspection time.
• Step 4: Tax Payment - The electronic payment system requires completion within three days of receiving the tax payment notice.
• Step 5: Release - After customs release, additional "post-clearance" steps like commodity inspection and phytosanitary checks must be completed.

Importers who master these techniques save an average of 20% on clearance costs:

• Pre-classification Application: Apply for a pre-classification ruling from customs to avoid post-declaration amendment risks.
• Consolidated Tax Payment: Monthly centralized tax payment reduces capital occupation, ideal for high-frequency importers.
• Guarantee Release: For goods requiring testing, a deposit can secure release before submitting final reports.

Three recently updated policies require special attention:

• Imported medical devices now require UDI code registration.
• Lithium battery shipments must provide UN38.3 test reports.
• Wood products must include original fumigation certificates (electronic copies no longer accepted).
