Every wire and cable shipment leaving the United States for an international destination requires a set of export documents. These documents serve three purposes: they satisfy US export regulations, they allow the shipment to clear customs at the destination country, and they create a paper trail that protects both the buyer and seller. This guide explains each document, who prepares it, and why it matters for your wire and cable order.
Export Documents at a Glance
The exact documents required for a wire and cable shipment depend on the shipping method, destination, and value of the goods. Here is a summary of the most common documents and who is responsible for each:
| Document | Purpose | Prepared By | Required? |
|---|---|---|---|
| Commercial Invoice | Primary customs document — declares value, description, and terms of sale | Seller (Ramcorp) | Always |
| Packing List | Itemizes physical contents, weights, and dimensions | Seller (Ramcorp) | Always |
| Bill of Lading (B/L) | Carrier’s receipt and contract of carriage (ocean freight) | Carrier or freight forwarder | Ocean shipments |
| Air Waybill (AWB) | Carrier’s receipt and contract of carriage (air freight) | Airline or freight forwarder | Air shipments |
| Electronic Export Information (EEI) | US government export filing via AES | Exporter or freight forwarder | Shipments >$2,500 per Schedule B |
| Certificate of Origin | Confirms country of manufacture | Manufacturer or seller | If required by the destination country, it must be requested during the quoting process (if manufacturer COO is unavailable, a statement of origin may be issued) |
| Shipper’s Letter of Instruction (SLI) | Exporter’s instructions to freight forwarder | Seller (Ramcorp) | When using a freight forwarder |
| Destination Control Statement (DCS) | Restricts diversion of controlled goods | Seller (Ramcorp) | When required by EAR |
Commercial Invoice
The commercial invoice is the most important export document. It is the primary document used by customs authorities at the destination to assess import duties and taxes, and it serves as the legal record of the transaction between buyer and seller.
A complete commercial invoice for a wire and cable shipment should include:
| Field | Description |
|---|---|
| Seller information | Ramcorp Wire & Cable — company name, address, phone, email |
| Buyer information | Full legal name and address of the purchasing company |
| Consignee | Party receiving the goods at destination (may differ from buyer) |
| Invoice number and date | Unique reference number for tracking and record-keeping |
| Product description | Detailed cable description including manufacturer, part number, conductor material, gauge, insulation type, and voltage rating |
| Quantity | Number of reels and total footage per line item |
| Unit price and total value | In US dollars (USD) |
| HS code | Harmonized System code for each line item (typically Chapter 85 for wire and cable) |
| Schedule B number | US 10-digit export classification code based on the HS system |
| ECCN or EAR99 | Export control classification for each line item |
| Country of origin | Country where the cable was manufactured |
| Incoterms | Agreed trade term (EXW, FCA, FOB, or CIF) per your order terms |
| Payment terms | Wire transfer (T/T) in advance |
| Total weight | Gross and net weight in both pounds and kilograms |
The commercial invoice must be accurate. Errors in product descriptions, values, or HS codes can cause customs delays, additional duty assessments, or fines at the destination. We prepare the commercial invoice for every international order and include it with the shipment documentation.
Packing List
The packing list is a detailed inventory of the physical contents of the shipment. While the commercial invoice focuses on value and trade terms, the packing list focuses on what is in each package, how much it weighs, and how it is packed.
A packing list for a wire and cable shipment typically includes:
- Number of packages (reels, pallets, crates)
- Contents of each package — cable type, part number, footage per reel
- Reel dimensions (diameter, width) and individual reel weights
- Gross weight and net weight per package (in pounds and kilograms)
- Total shipment weight and total number of packages
- Package marks and numbering
The freight forwarder uses the packing list to plan container loading, calculate volumetric weight for air freight pricing, and prepare the bill of lading. Customs authorities at the destination use it to verify that the physical shipment matches the commercial invoice. Discrepancies between the packing list and commercial invoice are one of the most common causes of customs holds.
Bill of Lading (B/L)
The bill of lading is the carrier’s receipt for the goods, the contract of carriage between the shipper and the carrier, and — critically for ocean freight — the document of title. The buyer typically needs the original bill of lading to claim the goods at the destination port.
There are two main types relevant to wire and cable shipments:
Ocean Bill of Lading (OBL): Issued by the shipping line or freight forwarder for ocean freight shipments. It is a negotiable document of title — meaning whoever holds the original B/L has the right to claim the cargo. For wire and cable shipments arranged through the customer’s freight forwarder, the forwarder typically issues the B/L. The B/L includes the shipper name, consignee, notify party, port of loading, port of discharge, description of goods, container number, seal number, and freight charges.
Straight Bill of Lading: A non-negotiable version that consigns the goods directly to a named party. Common for shipments paid in advance (like Ramcorp’s wire transfer terms) where there is no need for the B/L to serve as a financial instrument.
For shipments to the customer’s US-based freight forwarder, Ramcorp provides a domestic bill of lading or delivery receipt. The forwarder then issues the international B/L when the goods are loaded for export.
Air Waybill (AWB)
The air waybill serves a similar function to the bill of lading but for air freight shipments. Key differences from a B/L:
- An AWB is not a document of title — the consignee can claim the goods at destination with identification, without needing the original AWB
- An AWB is always non-negotiable
- AWBs are issued by the airline or air freight forwarder
The AWB includes the shipper and consignee details, airport of departure and destination, description of goods, number of pieces, gross weight, and declared value. For wire and cable, the AWB also references the commercial invoice number and any applicable export filing (EEI/AES) information.
Air freight is typically used for urgent international cable orders or smaller shipments where speed outweighs the higher per-pound shipping cost. Courier shipments (DHL, UPS, FedEx) generate their own waybill that functions similarly to an AWB.
Electronic Export Information (EEI) and AES Filing
US law requires exporters to file Electronic Export Information (EEI) through the Automated Export System (AES) for any shipment where the value of goods in a single Schedule B classification exceeds $2,500. Since most wire and cable orders exceed this threshold, EEI filing is required for the majority of international cable shipments.
The EEI filing includes:
| Data Element | What It Contains |
|---|---|
| USPPI | US Principal Party in Interest — the exporter (Ramcorp or the freight forwarder, depending on the arrangement) |
| Ultimate consignee | The party who will receive the goods in the foreign country |
| Country of ultimate destination | Where the goods will ultimately be delivered or consumed |
| Schedule B number | 10-digit US export commodity classification |
| ECCN or EAR99 | Export control classification |
| Quantity and value | Per Schedule B line item |
| Method of transportation | Ocean, air, ground |
| Port of export | US port or airport from which goods depart |
Once the EEI is filed and accepted, the AES system returns an Internal Transaction Number (ITN). The ITN must be provided to the carrier before the goods leave the United States. Without a valid ITN, the carrier cannot legally export the shipment.
Who files the EEI? This depends on the shipping arrangement. When Ramcorp ships directly via air freight or courier, we file the EEI (or our agent does). When the customer’s freight forwarder handles the international leg, Ramcorp issues a limited Shipper’s Letter of Instruction (SLI) to the forwarder containing the export data — product descriptions, Schedule B numbers, ECCN/EAR99 classifications, and values — and authorizing the forwarder to file EEI through AES. The freight forwarder then files the EEI as the authorized agent using the information provided.
Exemptions: Shipments to Canada are exempt from EEI filing in most cases unless the goods require an export license. Shipments under $2,500 per Schedule B number are also generally exempt, though certain items (controlled under an ECCN) require filing regardless of value.
Certificate of Origin
A certificate of origin (COO) confirms the country where the goods were manufactured. Some destination countries require a COO for import clearance, preferential tariff treatment under free trade agreements, or government procurement projects that mandate a specific country of origin.
There are several types of certificates relevant to wire and cable exports:
Manufacturer’s Certificate of Origin: Issued by the cable manufacturer (e.g., Southwire, Belden, General Cable/Prysmian) confirming the product was manufactured in a specific country. This is the most authoritative form of COO. Important: Manufacturer certificates of origin are provided only when available from the cable manufacturer and must be requested during the quoting process. Not all manufacturers provide COOs for every product, so confirm availability before committing to your buyer.
Statement of Origin: When a manufacturer’s certificate is not available, Ramcorp can provide a statement of origin confirming the known country of manufacture based on supplier documentation. This is not a certified document but is accepted by many customs authorities for standard commercial shipments.
Chamber of Commerce Certificate: Some countries require the COO to be certified by a local US Chamber of Commerce or endorsed by the destination country’s consulate. If your import regulations require this, let us know during the quoting process so we can coordinate the certification.
USMCA Certificate of Origin: For shipments to Mexico and Canada, a USMCA (formerly NAFTA) certificate of origin may allow the buyer to claim preferential (reduced or zero) tariff rates. The certificate must confirm the goods qualify as originating under the USMCA rules of origin. Not all wire and cable products qualify — it depends on the specific product, materials, and manufacturing processes.
Shipper’s Letter of Instruction (SLI)
The Shipper’s Letter of Instruction is a document from the exporter to the freight forwarder that provides all the information the forwarder needs to handle the shipment and file the EEI. The SLI is not a customs document — it is an internal instruction form, but it is critical for compliance because it transfers the export data from the seller to the party filing the export declaration.
A typical SLI for a wire and cable shipment includes:
- Exporter (USPPI) name, address, and EIN or SSN
- Consignee and ultimate consignee name and address
- Country of ultimate destination
- Product description, Schedule B numbers, ECCN/EAR99 classification
- Quantity, value, and weight per line item
- Shipping instructions (carrier preference, routing, insurance)
- Authorization for the forwarder to act as agent for export control purposes
When shipments are arranged through the customer’s freight forwarder, Ramcorp may issue a limited SLI containing the export data required for AES filing and authorizing the forwarder to act as agent for export control purposes. The forwarder then uses this data to file the EEI, prepare the bill of lading, and book the cargo. Note that many freight forwarders provide their own SLI template for the exporter to complete — in those cases, Ramcorp completes the forwarder’s form with the required export information.
Destination Control Statement (DCS)
The Destination Control Statement is a notice placed on the commercial invoice and bill of lading (or air waybill) warning that the goods are subject to US export controls and may not be diverted to another country or end user without authorization from the US government.
Under EAR Section 758.6, a DCS is required on shipments of items that have a specific ECCN (i.e., items on the Commerce Control List). For EAR99 items, a DCS is not legally required but is considered best practice by many exporters.
The standard DCS language is:
“These items are controlled by the U.S. Government and authorized for export only to the country of ultimate destination for use by the ultimate consignee or end-user(s) herein identified. They may not be resold, transferred, or otherwise disposed of, to any other country or to any person other than the authorized ultimate consignee or end-user(s), either in their original form or after being incorporated into other items, without first obtaining approval from the U.S. Government or as otherwise authorized by U.S. law and regulations.”
Record Keeping Requirements
US export regulations require exporters to maintain records of all export transactions for a minimum of five years from the date of export (EAR Part 762). This includes copies of all export documents: commercial invoices, packing lists, bills of lading, EEI filings, certificates of origin, SLIs, and any correspondence related to the transaction.
These records must be made available to BIS or other US government agencies upon request. Failure to maintain adequate export records can result in penalties even if the underlying export was otherwise compliant. Ramcorp maintains complete export documentation for every international shipment as part of our standard compliance process.
Note for buyers: Import duties, value-added tax (VAT), customs clearance fees, and local taxes at the destination are the responsibility of the buyer unless otherwise agreed in writing. We recommend keeping copies of all import documents alongside the export documents provided by Ramcorp for your own records and in case of customs audits in your country.
Frequently Asked Questions
What documents does Ramcorp provide for international orders?
Ramcorp prepares the commercial invoice, packing list, and Shipper’s Letter of Instruction for every international order. We also provide certificates of origin when available from the manufacturer, and coordinate EEI/AES filing either directly or through the freight forwarder. The carrier or forwarder issues the bill of lading or air waybill.
Do I need a freight forwarder for international cable orders?
For ocean freight shipments, yes — you will need a freight forwarder to handle the international ocean transport, container booking, and export filing. For air freight and courier shipments, Ramcorp can ship directly to many international destinations without a separate forwarder. We can recommend US-based forwarders if you do not already have one.
What is an ITN and why does it matter?
An ITN (Internal Transaction Number) is the confirmation code returned by the AES system after a successful EEI filing. The carrier requires the ITN before the shipment can leave the United States. Without it, the goods cannot legally be exported. The ITN is typically printed on the bill of lading or provided to the carrier electronically.
When is a certificate of origin required?
It depends on the destination country’s import regulations and the buyer’s requirements. Some countries require a COO for all imports; others only require it for government projects or when claiming preferential tariff rates under a trade agreement. If you need a certificate of origin, request it during the quoting process so we can confirm availability from the manufacturer.
What happens if export documents contain errors?
Errors on export documents can cause customs delays at the destination, additional duty assessments, fines, or even seizure of goods. Common errors include incorrect HS codes, mismatched product descriptions between the invoice and packing list, and wrong declared values. On the US side, errors in EEI filings can result in penalties from the Census Bureau or BIS. We double-check all documents before shipment to minimize these risks.
How long should I keep copies of export documents?
US regulations require exporters to retain export records for at least five years from the date of export. We recommend buyers also keep copies of all import documents (including customs entry forms, duty receipts, and correspondence with customs brokers) for at least the same period, as your country’s customs authority may audit imports within that timeframe.
