A container of dried seaweed cannot clear customs, be paid for under a letter of credit or be accepted by a processor without the right paperwork. For buyers importing from Indonesia, the core set is fairly standard, but the details depend on the destination country, the payment method and the end use. This checklist explains what each document is for and what to look at when it arrives.
The Core Commercial Documents
Commercial invoice. Issued by the seller, it states the parties, a description of the goods, quantity, unit price, total value, currency, Incoterm and payment terms. Customs in the importing country uses it to assess duties, so the description and value must be accurate.
Packing list. Lists the number of sacks or bales, net and gross weights, marks and lot numbers, and the container and seal numbers. It should match the invoice and the bill of lading exactly.
Bill of lading. Issued by the shipping line or its agent, it is the receipt for the goods, evidence of the contract of carriage and, in its negotiable form, a document of title. Under FOB, CFR and CIF terms, payment is often tied to presenting it. Our guide to choosing Incoterms explains how these terms interact with the documents.
Insurance certificate or policy. Required when the seller arranges insurance, as under CIF.
Origin, Health and Quality Documents
- Certificate of origin: confirms that the seaweed originates in Indonesia. A preferential certificate under a free trade agreement, such as those between ASEAN and its partners, may reduce import duty in the destination country, so buyers should say which form they need before shipment.
- Health or quarantine certificate: issued by the Indonesian quarantine authority where the importing country requires one for seaweed or fishery products. Requirements differ by destination and by whether the seaweed is for food or industrial use.
- Certificate of analysis (COA): reports laboratory results for the lot, such as moisture, clean anhydrous weed, foreign matter and, where agreed, microbiological or contaminant tests. It should state the laboratory, the methods and the sample it relates to.
- Inspection certificate: issued by an independent inspector, if the buyer has appointed one, covering sampling, quality, weight and container condition.
- Fumigation or treatment certificate: needed in some cases, for example where wooden pallets are used and must meet international phytosanitary rules for wood packaging.
Seaweed is classified under heading 1212 of the Harmonized System, with separate subheadings for seaweed fit for human consumption and other seaweed. The code on the invoice should match the intended use and the importing country’s tariff.
How Buyers Should Check the Set
Most document problems are inconsistencies rather than missing papers. When the documents arrive, work through them in this order:
- Names and addresses: the seller, buyer and notify party should be identical across all documents and match the contract.
- Description and code: the species, grade and tariff code should be the same everywhere.
- Quantities and weights: sack counts, net and gross weights should agree between invoice, packing list and bill of lading.
- Container and seal numbers: these must be consistent and match what arrives at port.
- Lot numbers: the COA and inspection certificate should refer to the same lots as the packing list, so that the results can be tied to the goods.
- Dates: the shipment date on the bill of lading should fall within the contract or letter of credit period, and certificates should be dated appropriately.
- Letter of credit terms: if paying by LC, check every document against the exact wording the credit requires.
A COA is only as reliable as the sample behind it, so it helps to know how the lot was sampled; see Sampling a Seaweed Lot. Document checks also belong in wider supplier vetting, covered in our due diligence checklist.
Getting It Right Before Shipment
The simplest way to avoid delays is to send the seller a written list of the documents required, with any specific wording, before the goods are packed. Ask for draft copies before the originals are issued, so that errors can be corrected while it is still easy.
Frequently asked questions
Does every seaweed shipment need a health certificate?
Not always. It depends on the importing country’s rules and the intended use. Check the requirement with your customs broker or authority before the contract is signed.
Can a COA replace my own testing?
It is a useful reference, but many buyers still test on arrival, especially with new suppliers. Agree in the contract which result prevails if they differ.
What if the documents do not match the goods?
Customs may hold the shipment and banks may refuse payment under a letter of credit. Report discrepancies to the seller immediately and keep written records.
