Customs clearance delays lead to missed launches, chargebacks, and unhappy customers. Most holds are caused by a few repeatable issues: bad paperwork, missing tax IDs, incorrect HS codes, or non-compliant product documents. This guide provides actionable steps for sellers shipping to the US, UK, EU, Australia, and Canada. Use the checklists to standardize your documents, pre-file when possible, and implement a swift escalation process.

1) Fix Commercial Invoice & Packing List Errors

The Problem:
Vague product descriptions, missing HS codes, or inconsistent values trigger inspections, adding days to your clearance time.

The Solution:

• Use a mandatory invoice template for all suppliers that includes: full consignee details, importer tax ID (EORI, VAT, EIN, or ABN), accurate 8-digit HS code, unit value & currency, total pieces, net/gross weights, country of origin, and Incoterm.

• Always attach a detailed packing list with box/pallet counts and dimensions.

• Send these documents to your broker 48–72 hours before arrival for pre-checking and pre-filing.

Client Case:
A UK beauty seller standardized supplier invoices and required HS codes in advance. Their routine shipments moved from multi-day holds to same-day clearance.

2) Synchronize Transport Documents

The Problem:
Mismatched or missing Bills of Lading (B/L) or Airway Bills (AWB) prevent carriers from releasing your cargo, even after customs approval.

The Solution:

• Ensure the B/L or AWB number exactly matches the reference on your commercial invoice.

• For US ocean imports, file the Importer Security Filing (ISF) on time and confirm vessel details with your carrier.

• Keep original documents or carrier release references easily accessible.

Client Case:
A North American importer avoided port detention by implementing a checklist that validated B/L numbers against the manifest 72 hours before arrival.

3) Manage Importer Tax IDs & Schemes

The Problem:
Shipments are held when authorities can’t match your goods to a valid importer tax ID like EORI (EU/UK), IOSS (EU), or VAT/EIN/ABN.

The Solution:

• Maintain a registry of importer tax IDs for each market you serve.

• Include the correct ID (EORI, IOSS, etc.) on every commercial invoice.

• For EU distance sales, use IOSS where eligible and ensure platform mappings are correct.

• Decide early between DDP (Delivered Duty Paid) or DAP (Delivered at Place) to avoid last-mile surprises.

Client Case:
An EU apparel brand added EORI/IOSS fields to their supplier template. Low-value B2C shipments stopped queuing at hubs and cleared seamlessly.

4) Handle Product Compliance for Special Items

The Problem:
Products like batteries, cosmetics, or food require certificates and prior notices. Missing documents lead to inspections and long delays.

The Solution:

• Batteries: Attach UN numbers, MSDS, and packaging declarations.

• Cosmetics: Have ingredient lists and responsible-person details ready.

• Food: File prior notices (e.g., US FDA) and ensure producer registrations are complete.

• Share all compliance documents with your broker and carrier before booking the shipment.

Client Case:
A gadget seller had repeated holds on power banks. After adding MSDS sheets and UN numbers to every shipment and pre-alerting their carrier, inspections were reduced to fast document checks.

5) Execute a Stuck-Shipment Playbook

The Problem:
Without a clear process, teams waste days on emails while demurrage and stockout costs pile up.

The Solution:
Adopt a 4-step SOP:

1. 1-Hour Doc Audit: Verify the invoice, HS code, B/L/AWB, and any licenses.

2. Broker Escalation: Call your broker directly and attach all digital files.

3. Containment Decision: Request an inspection slot, submit a corrected entry, or authorize a partial air shipment for critical items.

4. Root Cause Fix: Log the failure and update supplier templates to prevent recurrence.

Client Case:
A US electronics distributor used this playbook to resolve a container hold. Broker escalation and a partial air shipment kept their production line running, cutting recovery costs by 45%.
