Export document checklist for a frozen container: what should you check before the originals are sent?

Updated 11 October 2026 · 6 min read

The short answer

Before the originals of a frozen container are sent, check six areas across the documents: the container and its seal, the quantities and weights, the goods, parties and sales terms, the health certificate and the plants behind it, the dates and the carriage temperature, and the destination's own rules. Every value printed on two documents must tell the same story, and the on-board date must fall inside the window that the import permit and any letter of credit allow. Look at the draft bill of lading, when corrections are cheap, and at the final set again.

The documents for one frozen container

A frozen container travels with a set of documents, and every one of them describes the same box. Lay them out together:

the bill of lading, draft or final
the commercial invoice and the packing list
the health certificate, and the certificate of origin if the buyer, the bank or the destination asks for one
the import permit, such as the Philippine SPS import clearance
the letter of credit, if the sale is paid by one
any destination document: a halal certificate, a cargo tracking note, an advance cargo number

Look at the set twice: when the draft bill of lading arrives, because a draft is easy to correct, and again on the final set before the originals are sent to the buyer or presented to the bank. A signed health certificate can only be corrected by the authority that issued it, so look at its draft too when you can.

Six areas to check

Every value printed on two documents must tell the same story, and every date must fall inside the window that the import permit and the credit allow. Grouped by what they protect, the checks fall into six areas:

Area	What it covers	Why it matters
1. The container	The container and seal numbers	They tie the papers to one box. A wrong character names another container or another seal.
2. Quantities and weights	Cartons, net weight and gross weight	Banks compare totals, and inspectors count what arrives.
3. Goods, parties and terms	The goods, the companies in each box, the sales term	A bank pays only against documents that do not conflict with the credit or with each other.
4. Health certificate and plants	The certificate, the plants the meat comes from, the labels	The destination accepts meat only from approved plants, certified on the model it agreed.
5. Dates and temperature	The on-board date, the import permit, the credit, the carriage temperature	A late loading can cost the import permit or the credit, and thawed meat can be seized.
6. The destination's own rules	The numbers and documents a country adds	Some carriers will not load, and some ports will not release, without them.

The rules behind each area

The container. Under ISO 6346, a container number has four letters (three for the owner and one for the equipment category, U for a freight container), six digits and a check digit: CSQU3054383, for example. The seal on the door has its own number, and both appear on several documents.

Quantities and weights. Net weight is the product alone and gross weight adds the packing. The invoice usually shows net weight and the bill of lading gross. See gross weight vs net weight on a packing list.

Goods, parties and terms. Under a letter of credit, the invoice must describe the goods as the credit does, and the other documents may use general terms that do not conflict with it (UCP 600, articles 18(c) and 14(e)). The shipper need not be the seller (article 14(k)). The sales term decides who pays the sea freight: under CFR and CIF the seller, under FOB the buyer. See what must match between the bill of lading, invoice and packing list, consignee vs notify party and FOB, freight and insurance on the invoice.

Health certificate and plants. The exporting country's veterinary service issues the certificate on the model the destination agreed, and the plants it names must be approved for that destination. For the Philippines, meat labels must also show the expiry date and the dates of manufacture and packing. See how to read a plant approval number and plant numbers and the SPS clearance.

Dates and temperature. The on-board date on the bill of lading is the date of shipment (UCP 600, article 20(a)(ii)). Under a credit it must not be later than the latest shipment date, and the documents must be presented within the period the credit sets, or within 21 calendar days after shipment if it sets none, and never after the credit expires (article 14(c)). The Philippine SPS import clearance must be issued before loading, covers one shipment, and carries a "must ship out by" date; goods loaded later face confiscation procedures, unless the delay has an accepted cause such as force majeure or port congestion. See the SPS import clearance.

For temperature, the EU's rule for quick-frozen food is -18 °C or lower, with brief rises of no more than 3 °C allowed during transport. Importing countries set their own limits: the Philippines requires frozen meat at no higher than 0 °C and treats signs of thawing as grounds for seizure, and Ghana's Food and Drugs Authority asks for -18 °C, plus or minus 3 °C.

The destination's own rules. Each destination adds its own. Egypt needs an ACID number for every shipment, and carriers such as ONE will not load without it. Several African countries need a cargo tracking note for each bill of lading: see cargo tracking notes: ECTN, BESC and FERI. Qatar asks for the invoice number and the health certificate number on the halal certificate. For the whole Philippine set, see documents to export frozen pork to the Philippines.

An example

Tern Bay Foods sells one container of frozen chicken cuts (HS 0207.14) to Island Table Corp. in Manila, paid by letter of credit (the names are made up). The SPS import clearance was issued on 2 September 2026 and must ship out by 1 December 2026. The credit's latest shipment date is 15 November 2026, it expires on 30 November 2026, and it sets no presentation period. The goods go on board on 13 November 2026.

The dates work: 13 November is inside the clearance and before the latest shipment date. Twenty-one days after shipment would be 4 December, but the credit expires on 30 November, so that is the real deadline for presenting the documents.

The container does not. The bill of lading, the invoice and the packing list give it as CSQU3054383; the health certificate says CSQU3054833, with two digits swapped. Only the authority that signed the certificate can correct it, so the exporter asks the veterinary office for a corrected certificate at once: the deadline is 30 November, not 4 December. The terms on this page are explained in the shipping document glossary.

Questions people ask

Which documents does a frozen meat or fish export usually need?

A frozen meat or fish container typically travels with a commercial invoice, a packing list, a bill of lading and a health certificate from the exporting country's veterinary authority. Many destinations or buyers add a certificate of origin, an import permit issued to the importer, and documents such as a halal certificate. The exact list depends on the destination and on how the sale is paid.

When should the export documents be checked?

Twice. First when the draft bill of lading arrives, because a draft is easy to correct, and again on the final set before the originals go to the buyer or the bank. A signed health certificate can only be corrected by the authority that issued it, so check its draft as well when you can.

How long do I have to present documents under a letter of credit?

Within the period the credit sets. If it sets none, within 21 calendar days after the date of shipment, and in any case no later than the credit's expiry date (UCP 600, article 14(c)). When the credit expires first, the expiry date is the deadline.

What are the most common mistakes in export documents?

For letters of credit, the ICC names timing problems as the most common discrepancies: late shipment, late presentation and an expired credit. A significant number come from poorly prepared documents, such as conflicting data between documents, a goods description that differs from the credit, wrong ports, missing or wrong endorsements and missing or wrong on-board notations.

Do the documents have to be identical?

No. Under UCP 600, article 14(d), data in one document need not be identical to the others, but must not conflict with them. A general goods description on the bill of lading, for example, does not conflict with the full description on the invoice (article 14(e)).
