7.2 Import/export compliance

Customs authorities act as the ultimate physical gatekeepers in the international supply chain. They function independently of your production schedules or engineering urgencies. If shipping documentation is inaccurate or incomplete, the physical flow of goods stops, often indefinitely. Compliance is a critical master data requirement that should be validated before the freight forwarder collects the cargo. Material held in customs represents capital tied up without operational benefit.

The required document suite

A complete and accurate set of documents must be ensured to accompany every international shipment. Missing or conflicting data frequently triggers regulatory holds.

1. Commercial invoice (CI)

• Function: The official financial declaration of value.
• Requirement: Must list the Unit Price (matching the PO), Total Value, Currency, and agreed Incoterm.
• Important Detail: Items shipped as “Samples” or “Warranty Replacements” cannot be declared with zero value. They must have a nominal value stated for customs purposes (e.g. “Value for Customs Purposes Only: $10.00”). Zero-value invoices often trigger immediate audits.

2. Packing list (PL)

• Function: The physical map detailing the contents of the shipment.
• Requirement: Must align exactly with the Commercial Invoice. Net Weight, Gross Weight, and Dimensional details should be accurate measurements, not rough estimates.
• Important Detail: If a Packing List indicates “Box 3 contains PCBAs” but customs inspection reveals cables, the shipment may be delayed or seized due to misdeclaration.

3. Harmonized system (HS) codes

• Function: The universal classification system determining duties, taxes, and regulations.
• Ownership: The Buyer generally owns the final HS classification for imported goods. Relying entirely on a supplier’s generic classification for proprietary hardware must be avoided.
• The Risk: An incorrect HS code leads to an incorrect duty rate. Underpaying is a compliance risk; overpaying erodes profit margins.
• The Protocol: It must be determined if a custom PCBA is best classified as a “part of a computer” (often duty-free) or a “control board” (variable duty). This classification must be defined in the Item Master before releasing the PO.

4. Country of origin (COO)

• Function: Vital for determining eligibility for Free Trade Agreements (FTA) or the application of specific tariffs.
• Requirement: Physical marking on the product or its packaging is usually required (e.g. “Made in [Country]”).
• The Distinction: COO refers to where the product was manufactured, not simply where it was last shipped from. A component manufactured in one country but shipped from an intermediate distribution hub retains its original Country of Origin.

The pre-shipment review

Implementing a “Green Light” process should be considered. This ensures the forwarder only collects goods after the internal Logistics or Procurement team has reviewed the documentation.

• Step 1: The supplier provides draft Commercial Invoice (CI) and Packing List (PL) copies via email prior to shipping.
• Step 2: The buyer verifies the following key elements:
  • Do the prices match the Purchase Order (PO)?
  • Is the correct Harmonized System (HS) Code applied?
  • Is the specified Incoterm accurate?
• Step 3: The buyer issues an “Approved for Booking” confirmation.
• Step 4: The supplier proceeds to hand over the freight to the forwarder.

Critical Factor

Processes where the vendor hands shipping documents directly to the carrier without prior review must be avoided. Document mismatches are a primary cause of customs delays.

Managing broker interaction & escalations

Customs Brokers act on your behalf, but they rely on the information provided to them.

Defining expectations

A Standing Letter of Instruction (SLI) must be provided to the designated broker. This document should instruct them to contact the internal team for HS code clarification on unfamiliar parts, rather than defaulting to generic classifications like “Electronic Component.”

Managing customs holds

1. Assess: When an issue arises, stay calm and gather the facts from the broker.
2. Identify: The specific “Notice of Action” or official “Information Request” must be requested.
3. Respond: Requested technical materials, schematics, or proof of payment must be provided promptly and clearly.
4. Improve: If a shipment was held over valuation or classification, the internal Item Master must be updated or requesting a formal binding ruling from customs considered to streamline future shipments.

Record retention

Customs audits frequently occur retrospectively, sometimes years after the import. A clear digital audit trail linking the transaction must be maintained:

PO → Commercial Invoice → Customs Entry Documentation → Proof of Payment

It must be ensured these records are stored securely in a centralized repository rather than personal email inboxes.
