Shekou-Sihanoukville 2x40HQ Machine Parts CIF

When a production line depends on imported parts, unstable shipping schedules and recurring customs errors are not just annoyances. They are business threats.

This case details how GWT Shipping rescued a weekly supply chain of 2 x 40HQ machine parts from Shenzhen to Sihanoukville, Cambodia.

By replacing an unprofessional forwarder with a structured, compliance-focused approach, we eliminated customs re-filings and established a reliable 10-day delivery cycle.

状況とクライアント概要

Client	A Trading Company (supplying a manufacturer in Cambodia).
Contract	CIF Sea Freight Export.
Shipment	2 x 40HQ Machine Parts (Weekly volume).
Route	Shekou Port (Shenzhen) to Sihanoukville, Cambodia.
Objective	Stabilize the supply chain, eliminate customs declaration errors, and ensure on-time delivery to prevent production stoppages.
Prior Pain Points	The previous forwarder was unprofessional, leading to unstable vessel schedules (frequent delays) and customs declaration errors that required “deleting and re-filing” (a serious compliance risk). This caused missed deliveries and heavy financial losses for the factory.

課題

GWT Shipping took over this account in October 2022 to fix a broken process. We identified three critical root causes:

Schedule Instability: The previous forwarder selected unreliable carriers, resulting in frequent rolling and delays that disrupted the factory’s production planning in Cambodia.
Factory Inexperience & Complex Cargo: The Shenzhen manufacturer was unfamiliar with export procedures. The cargo was “mixed” and “sensitive” (complex parts classification), leading to messy packing lists that triggered customs errors.
Compliance Risk: The history of “deleted declarations” indicated a lack of pre-shipment auditing. Continuing this pattern risked a customs audit or penalties.
Missed Cost Savings: The client was unaware they were eligible for tax exemptions at the destination, unnecessarily increasing their landed cost.

GWT Shippingのソリューションと対応

Our team implemented a four-step stabilization plan focused on schedule reliability and customs precision.

Step 1: Carrier Analysis & Stabilization

実施内容： GWT’s operations team analyzed the one-month performance records of all carriers on the Sihanoukville route.
決定： We selected SITC, a carrier with whom GWT has a deep partnership. SITC offers the fastest transit time and, crucially, high schedule reliability on this intra-Asia lane.
結果： We secured guaranteed space, eliminating the risk of “rolled” containers and establishing a fixed departure schedule.

Step 2: Factory Guidance & Process Control

実施内容： Recognizing the factory’s lack of experience, GWT’s team stepped in to guide the production side.
実行： We coordinated directly with the factory to align production completion with the SITC vessel schedule. We also educated their staff on proper cargo classification and packing list preparation to handle the “mixed” nature of the machine parts.

Step 3: AEO Customs Audit (Preventing Errors)

実施内容： To stop the cycle of “declaration errors,” GWT utilized its AEO-certified customs team.
調整： We implemented a strict Pre-Shipment Audit. We collected the Packing List and Invoice before the cargo left the factory. Our specialists reviewed the sensitive product codes and data accuracy before submitting to customs.
結果： This zero-tolerance approach for errors ensured 100% smooth releases, completely eliminating the need for re-filings.

Step 4: Tax Optimization (Value Add)

実施内容： GWT analyzed the trade agreements between China and ASEAN regarding the specific machine parts.
結果： We confirmed the goods were eligible for preferential duty rates. We immediately arranged for the issuance of the Certificate of Origin (Form E).
Benefit: This significantly reduced the import duty costs for the client in Cambodia.

成果と効果

By treating the shipment as a supply chain project rather than a simple booking, GWT turned a problem lane into a competitive advantage.

10-Day End-to-End Turnaround: We established a streamlined cycle: From factory completion -> GWT Booking -> Arrival in Sihanoukville now takes just 10 days, ensuring the factory never stops production.
Weekly Stability: The client now successfully ships 2 x 40HQ containers every week with zero schedule disruptions.
Zero Customs Errors: Our pre-audit process eliminated the declaration errors and delays that plagued the previous forwarder.
Exclusive Partnership: Satisfied with the professional turnaround, the client appointed GWT as their Designated Agent in China, handing over all air and sea freight operations for their manufacturing group.

結論

This case demonstrates that “professionalism” in logistics is measurable: it looks like stable schedules, accurate documents, and lower costs.

GWT Shipping replaced chaos with a reliable, 10-day delivery loop by combining our strategic carrier partnerships (SITC) with our AEO customs expertise. We don’t just move containers; we stabilize production lines.

クライアントの声

Before GWT, we had constant delays and customs errors that hurt our production. GWT fixed the schedule and the paperwork immediately. Now our weekly shipments arrive in 10 days like clockwork.
