Customs Declaration Delay Causing Demurrage? Three-Step Response Strategies and Professional Solutions

A shipment of food-grade collagen peptides dispatched from Yokohama Port,Japan,has been waiting for more than 14 days at Yangshan Port,Shanghai.Yu,the supervisor of the consignee,is growing increasingly anxious.He knows that every extra day sees invisible demurrage fees accumulating on the books,and urgent calls from downstream clients only add to his stress.Such scenarios are not uncommon in import business in 2026,especially for food,cosmetics,medical devices and other goods from strictly regulated regions like Japan and the EU.Their complex access requirements and quarantine procedures often extend the document preparation period,triggering customs declaration timeliness alerts.

There are clear legal time limits for import customs declaration.According to the current Customs Law and supporting regulations,the consignee of imported goods shall declare to the customs within 14 days from the date the means of transport is declared to have entered the country.This "14-day" period is a rigid starting point.For late declaration,the customs will collect demurrage fees daily in accordance with the law,starting from the 15th day after the means of transport is declared to have entered the country and ending on the date the customs accepts the declaration.The daily demurrage fee is 0.05% of the dutiable value of the goods.If goods remain undeclared for more than three months,the customs has the right to take them over and sell them according to law.For high-value goods or urgently needed production materials,the losses caused by demurrage fees and cargo disposal risks may far exceed expectations.

When serving projects such as imported Japanese collagen peptides and other high-end consumer raw materials,Zhongshen’s core role first lies in accurate control of the entire process’s time nodes and pre-emptive risk management.The team does not wait until the goods arrive at the port to take action,but moves the service start point forward to the eve of overseas shipment.Through a mature mechanism of pre-examination,pre-classification and contingency planning,they resolve the risk of "late declaration" as early as possible before it occurs.

Phased Breakdown: Full-Process Timeliness Control from Documents to Quarantine

Phase 1: Document Pre-examination and Compliance Preparation

Food raw materials exported from Japan have relatively high compliance thresholds.Take collagen peptides as an example: importers must confirm in advance whether the product has obtained the registration qualification of overseas production enterprises from the General Administration of Customs of China,and check whether the contents of the "official health certificate" and "certificate of origin" issued by Japan fully meet the requirements of the Chinese side.In addition,the sample Chinese label of the product must comply with national food safety standards such as GB 7718,and its ingredients and functional claims shall not exceed the scope of regulations.

Zhongshen’s customs affairs team will require customers to provide a full set of trade documents and technical files for pre-examination before the goods are shipped.Common issues found in this link include:

• The product name description on the overseas invoice is too general and does not match the precise specifications required for HS code classification.
• The format or official seal of the health certificate does not comply with the latest filing specifications.
• The Chinese label emphasizes health functions that have not been approved by China.

The team will guide customers to contact overseas suppliers to correct or supplement documents,ensuring that all documents are complete and accurate before the goods arrive at the port,avoiding being rejected by the customs during declaration due to document issues and wasting valuable declaration time.

Phase 2: Port Declaration and Timeliness Control

Once the customs receives the entry data of the goods’ means of transport,the 14-day countdown starts immediately.Zhongshen’s operating system will track this status synchronously and automatically trigger the declaration preparation process.Based on the pre-examined and correct documents,the customs affairs team will complete the pre-entry and review of the customs declaration form before the goods actually arrive at the port,and only wait for the complete manifest information to make the official declaration.

However,even with sufficient preparation,accidents may occur.For example,last year,a client Mr.Yu,whose imported batch of Japanese matcha powder had a three-day delay in manifest data transmission due to a shipping company system issue,resulting in a passive delay in the official declaration start time.Facing the possible demurrage fees,Zhongshen’s handling steps are as follows:

First,immediately confirm the specific cause of the manifest abnormality with the shipping agent and the terminal,and keep written communication records.Second,when the customs accepts the declaration,voluntarily attach a situation explanation and the certification document issued by the shipping company to explain that the declaration delay was not due to the consignee’s subjective fault.According to relevant clauses of the Measures for the Collection of Import Cargo Demurrage Fees by the Customs,the consignee may apply to the customs for demurrage fee reduction or exemption for special situations such as declaration delay caused by the carrier’s responsibility of the means of transport.Finally,the demurrage fee application for this shipment was approved by the customs.

The table below shows an example of demurrage fee calculation for different overdue days,assuming the dutiable value of the goods is USD 100,000:

This fee itself may be manageable,but the hidden costs of storage fees,container detention fees and supply chain interruptions caused by cargo detention are the real pain points for enterprises.

Phase 3: Customs Inspection and Quarantine Coordination

For imported food from Japan,customs inspection and import food quarantine are mandatory procedures,and inspection orders may be issued at any time.Once goods are selected for inspection or sampled for testing,their clearance time will inevitably be extended.At this point,professional on-site coordination capabilities are crucial.

Zhongshen has long-term cooperative customs declarers and coordinators at major ports,who can respond to inspection orders immediately and accompany customs officers or quarantine personnel on-site.For products like collagen peptides,the quarantine department may focus on testing heavy metals,microbial indicators and nuclear radiation residues (for products from some regions of Japan).The team will prepare materials such as product composition analysis reports and production process descriptions in advance,efficiently cooperate with the inspection on-site,and communicate clearly with officials on professional issues,avoiding unnecessary delays in inspection time due to poor communication or incomplete materials.

Experience Sharing: Turning Passive into Active Timeliness Management

There was a Ms.Tan who operated Japanese maternal and infant products.Due to unfamiliarity with new regulations,her imported batch of baby food puree spent too much time on label review,and the documents were still not complete when the goods arrived at the port.Seeing that the demurrage fee collection date was approaching,she turned to Zhongshen for emergency assistance.

After taking over the case,the team divided into two teams: one team quickly corrected and adjusted the existing documents for compliance,prioritizing ensuring that the main content of the customs declaration form could be declared; the other team simultaneously pre-communicated with the quarantine department about label modifications and clarified the rectification path.While declaring,they submitted a situation explanation and a commitment to submit label filing documents later.This strategy of "declaration and rectification in parallel",with the approval of the customs,won a buffer period for the final compliance of the label,successfully avoiding long-term detention of the goods due to document details,and greatly reducing the number of days for which demurrage fees were incurred.

This case shows that in the face of timeliness pressure,professional agency services do not just follow procedures mechanically.Instead,based on a deep understanding of regulations and good communication with regulatory authorities,they find the most efficient solutions for enterprises within the compliance framework.

Conclusion

The consequences of overdue import customs declaration are far more than just a demurrage fee.It disrupts production plans,erodes profits and damages corporate reputation.For imported goods involving complex access requirements,entrusting customs declaration affairs to an agency like Zhongshen with more than 20 years of practical experience is essentially purchasing a systematic risk buffer and efficiency optimization mechanism.Through pre-emptive document review,accurate classification prediction,efficient on-site coordination and skilled use of regulatory reduction clauses,this mechanism can turn passive response to "late declaration" into active timeliness management across the entire supply chain.In the context of the 2026 international trade environment that still emphasizes compliance and efficiency,the value of this professional support is reflected in every shipment that clears customs on time and smoothly,providing a solid guarantee for the stability of the enterprise’s supply chain and cost controllability.
