Top 5 Reasons Your Shipment Gets Delayed at Customs – and How to Avoid It

In the fast-paced world of international shipping, customs delays can be a major frustration. For South African importers and exporters, a holdup at the border can result in lost time, increased costs, and unhappy customers. The good news? Many customs delays are preventable with the right knowledge and preparation.

Here are the top five reasons your shipment might get delayed at customs – and how you can avoid them.

 

1. Incomplete or Inaccurate Documentation

Why it causes delays: Customs authorities require detailed and accurate paperwork to clear shipments. If your documents are missing, incomplete, or have errors, the shipment will be flagged for further inspection or held until corrections are made. 

Common mistakes:

  • Incorrect harmonised tariff codes (HS codes).
  • Missing commercial invoices.
  • Incomplete packing lists.
  • Errors in the bill of lading or airway bill.
  • Missing permits or certificates (e.g., phytosanitary or veterinary).

 

How to avoid it:

  • Double-check all documentation before submitting.
  • Work with a licensed customs clearing agent, like Inter-Sped, who can ensure all paperwork is correctly prepared and submitted.
  • Use digital document management systems to track and verify your shipment paperwork.

 

2. Incorrect Tariff Classification (HS Code)

Why it causes delays: The harmonised system (HS) code determines duties, taxes, and necessary import requirements. Using the wrong code can result in the shipment being incorrectly processed, reassessed, or halted. 

How to avoid it:

  • Ensure your products are classified correctly by consulting with experts or using reliable classification tools.
  • Use a freight forwarding partner like Inter-Sped, who specialises in customs compliance and tariff classification.

 

3. Unpaid Duties or Taxes

Why it causes delays: If duties, VAT, or other applicable taxes are not paid or arranged for in advance, the goods will be held by customs until payment is received. This is a frequent cause of unnecessary delays. 

How to avoid it:

  • Make sure you understand your incoterms and who is responsible for customs fees.
  • Pay duties and taxes ahead of the shipment’s arrival when possible.
  • Consider setting up a bond or using a clearing agent who offers financial facilitation.

 

4. Random or Risk-Based Inspections

Why it causes delays: Even if everything is in order, customs may randomly select your shipment for inspection. Additionally, if your shipment raises any red flags (e.g., vague product descriptions or high-risk country of origin), it may be subject to further scrutiny. 

How to avoid it:

  • Be clear and specific with product descriptions.
  • Use reputable and compliant suppliers.
  • Maintain transparency and consistency in your shipping documents.
  • Build a clean customs history to reduce the likelihood of risk-based flags.

 

5. Missing or Incorrect Import Permits and Licences

Why it causes delays: Certain goods require permits or licences before they can be imported or exported. If these are not in place, customs will not release the shipment. 

Examples include:

  • Pharmaceuticals.
  • Chemicals.
  • Food and beverage products.
  • Electronics.
  • Agricultural goods.

 

How to avoid it:

  • Research and confirm whether your product requires special authorisation.
  • Partner with a clearing agent who stays current on regulatory changes.
  • Apply for permits well in advance, as approval processes can be time-consuming.
