What Businesses Need Before Customs Clearing Can Begin

Customs clearing does not begin only when a declaration is submitted. It begins with the information and documents that support that declaration.

For importers and exporters, this means the clearing process can come under pressure before cargo reaches a port, airport, border or warehouse. 

A shipment may be ready to move, the supplier may be confirmed and transport may be arranged, but customs clearing can still be delayed if the required documents, cargo details or clearance information are incomplete.

From our experience, customs clearing delays often start before the shipment reaches the formal clearing stage. They begin when invoices are unclear, packing details are incomplete, cargo descriptions are too vague, tariff considerations have not been checked or the customs status of the goods is not understood.

That is why businesses should prepare the right information before customs clearing is expected to begin.

Why Preparation Matters Before Customs Clearing

Customs clearing depends on accurate information.

Before a shipment can be cleared, the goods need to be understood from both a commercial and customs perspective. The documents must support what is being imported or exported, the cargo details must be clear and the movement type must be understood.

This is why customs clearing for businesses should not be treated as a last-minute paperwork step. If information is missing or inconsistent, the shipment may be delayed while documents are corrected, requirements are clarified or additional supporting information is requested.

Preparation also helps connect customs clearing to the wider logistics movement. Transport, storage, delivery, pre-clearance and bonded movement may all depend on the customs position of the cargo.

The earlier the correct information is checked, the easier it is to identify issues before the shipment reaches a pressure point.

Key Information BAC Logistics May Need Before Customs Clearing Can Begin

The exact requirements will depend on the shipment, cargo type, origin, destination and customs process involved. However, there are several key areas businesses should prepare before customs clearing can begin.

1. Commercial Invoice

The commercial invoice is one of the most important documents in the customs clearing process.

It helps confirm the commercial details of the shipment, including who is selling the goods, who is buying them, what the goods are, their value, and the terms of the transaction.

A commercial invoice may need to show the seller and buyer details, invoice number and date, description of goods, quantity, value, currency, country of origin, where relevant, and Incoterms where applicable.

The invoice must support what is actually being imported or exported. If the description is too vague, the values are unclear, or the details do not match the shipment, customs clearing can be delayed.

2. Packing List

The packing list connects the documents to the physical cargo.

It helps show how the goods are packed, how many packages are being moved, what the weight and dimensions are, and how the cargo is arranged for transport, storage or inspection.

A packing list may include package count, carton or pallet details, gross and net weight, dimensions, item breakdown, and packaging type.

This information becomes especially important when cargo needs to be checked, inspected, stored, consolidated, moved onward, or matched against the commercial invoice.

If the packing list does not align with the shipment, it can create uncertainty during customs clearing or physical handling.

3. Accurate Cargo Details

Customs clearing depends on knowing what the goods are.

A general description may be enough for a basic transport conversation, but it is not always enough for customs purposes. Customs may need clear cargo details to understand the product, its use, its value, any applicable requirements, and whether additional documents are needed.

Businesses should be ready to confirm what the goods are, what they are made of or used for, where relevant, the quantity, value, packaging, condition, and whether the goods are new, used, regulated, bonded, high-value, or permit-sensitive.

Vague cargo descriptions often create avoidable delays. The clearer the cargo information is, the stronger the customs clearing process can be from the start.

4. Origin, Destination, and Parties Involved

Customs clearing also depends on understanding the movement.

We may need details such as the country of origin, country of export, destination country, importer, exporter, supplier, consignee, and final delivery or receiving point.

These details matter because customs clearing is not only about the goods. It is also about where they are coming from, where they are going, and who is responsible for the shipment.

If importer, exporter or consignee details are incomplete or inconsistent, the clearing process may be delayed while the information is corrected or clarified.

The movement must be clear from both a customs and logistics perspective before clearing can be prepared properly.

5. HS Code and Tariff Considerations

HS code and tariff considerations can affect duties, taxes, permits and customs treatment.

Some businesses may already have a tariff code for the goods they import or export. In other cases, the classification may need to be checked or confirmed before clearing begins.

This section should not be treated as a guesswork exercise. If tariff considerations are unclear, they should be reviewed before the shipment is under pressure.

Customs consultations can help businesses clarify tariff-related questions, documentation requirements or product-specific considerations before customs clearing begins.

The goal is not to overcomplicate the process. The goal is to make sure the customs position is understood early enough to avoid unnecessary delays.

6. Permits, Licences and Supporting Documents

Some goods require more than a commercial invoice and packing list.

Depending on the product, businesses may need permits, licences, certificates, product information or other supporting documents before customs clearing can proceed.

This can apply to regulated goods, liquor or controlled products, used equipment, industrial cargo, mining-related cargo, high-value goods or products that require specific approvals.

If these requirements are only identified after the cargo has arrived or is already moving, the shipment may be delayed while the correct documents are obtained.

Businesses should confirm whether the cargo has any special documentation requirements before customs clearing is expected to begin.

7. Cargo Status and Movement Type

Customs clearing is also affected by the status of the cargo and how it is moving.

We may need to understand whether the cargo is being imported, exported, moved in transit, stored under customs control, moved under bond, cleared before arrival or held before final clearance.

This matters because different movement types can affect the customs process, transport planning and storage requirements.

For some shipments, pre-clearance services may help prepare the customs process before cargo arrives or before it reaches a pressure point. For cargo that cannot be cleared immediately or needs to remain under customs control, bonded warehousing services may form part of the wider logistics plan.

Customs clearing depends not only on documents, but also on the customs status and movement type of the cargo.

When Customs Clearing Can Be Delayed

Customs clearing delays often start with missing or inconsistent information.

Common causes include missing invoices or packing lists, vague cargo descriptions, incorrect values or quantities, importer or exporter details that do not align, tariff uncertainty, missing permits, unclear cargo status or documents being prepared too late.

These issues may seem small at the start, but they can affect the full movement. A truck may be ready, a shipment may have arrived and a delivery deadline may be in place, but customs clearing cannot proceed properly if the required information is incomplete.

The best way to reduce this risk is to prepare and check the clearing information before the shipment reaches a point where delays become more costly.

Why Early Customs Guidance Helps

Early customs guidance helps businesses understand what is needed before the cargo reaches a pressure point.

It can help identify missing information, clarify document requirements, highlight permit or tariff concerns, assess whether pre-clearance may apply and determine whether bonded storage or customs-controlled movement should be considered.

This is where BAC Logistics adds value.

Our customs team helps businesses understand what information is needed before clearing can begin, so the process is not treated as a last-minute paperwork exercise. Where customs clearing, transport, storage or onward delivery need to align, early guidance gives the movement more structure.

For businesses looking for a customs clearing agent in Johannesburg, the value is not only in submitting documents. It is in understanding what is required before submission, so customs clearing can begin from a stronger position.

Customs Clearing Preparation Checklist

Before customs clearing can begin, businesses should prepare:

• Commercial invoice

• Packing list

• Accurate cargo description

• Weight, quantity, and packaging details

• Origin and destination information

• Importer, exporter, and consignee details

• HS code or tariff considerations

• Permits, licences, or supporting documents, where applicable

• Cargo status and movement type

• Pre-clearance or bonded warehousing requirements where relevant

This checklist does not replace professional customs guidance, but it gives importers and exporters a clearer starting point before customs clearing begins.

Prepare Before Customs Clearing Begins

Customs clearing depends on preparation.

The earlier the documents, cargo details, tariff considerations, and movement requirements are checked, the easier it is to identify issues before the cargo is delayed.

For importers and exporters, the key is not only having paperwork available. The information must be accurate, complete, and aligned with the shipment.
