Everything in this catalogue ships within the United States, so an order placed here does not cross a border. Two situations still make import paperwork a buyer's concern. A laboratory outside the country may be receiving research material from abroad and wants to know what should travel with it. And a buyer anywhere may be auditing a supplier whose own stock was imported, in which case the supplier's import file is part of what who can purchase research-use-only material and the rest of the due-diligence set are checking.
This guide is procedural. It describes the documents a cross-border shipment of research material customarily carries, how goods are classified for customs, what happens when a consignment is held, and what to keep afterwards. It is not legal advice, it does not state what any particular shipment is permitted, and where a decision rests with a customs authority or a licensed broker it says so.
Who does what
In the United States, the importer of record files an entry with Customs and Border Protection, usually through a licensed customs broker. CBP's guidance for new importers is explicit that even when a broker is used, the importer of record is ultimately responsible for the correctness of the entry documentation. The entry summary itself is CBP Form 7501, which CBP relies on to determine appraisement, classification and origin of the imported goods.
Products that fall within the Food and Drug Administration's remit are also screened by FDA. FDA's import programme states that imported FDA-regulated products are electronically screened before they enter the country, and that such products must meet the same requirements whether imported or produced domestically. Whether a given consignment of research material is within that remit is a determination for the filer and the agencies, not for a guide.
The document set
| Document | Prepared by | What it is for |
|---|---|---|
| Commercial invoice | Exporter (seller) | Describes, quantifies and values the goods; the basis for entry, appraisement and classification |
| Packing list | Exporter | Carton-by-carton contents, matched to the invoice and to what arrives |
| Research-use declaration | Exporter, sometimes countersigned by importer | States the material is for laboratory research and not for human or veterinary use; supports the description on the invoice |
| Safety data sheet | Manufacturer or distributor | Hazard classification and transport information (Sections 2 and 14); read by carriers and by customs |
| Certificate of analysis | Testing laboratory or supplier | Identity, purity and content of the lot; supports the description and allows the importer to check what arrived |
| Entry documentation | Importer of record or broker | The filing with customs, including the tariff classification and declared value |
| Air waybill or bill of lading | Carrier | Contract of carriage and tracking |
| Temperature record | Shipper or carrier | Data logger output covering the whole transit, including any period under hold |
Documents customarily prepared for a cross-border shipment of research material, who prepares each, and what it does. Requirements for any specific shipment are set by the authorities at both ends.
The commercial invoice
The commercial invoice is the document customs reads first, and in the United States its required content is set out in 19 CFR 141.86. Among the items it must set forth are the port of entry to which the goods are destined; the parties to the sale and the time and place of it; a detailed description of the merchandise, including the name by which each item is known and its grade or quality, with the marks and numbers of the packages; quantities in the weights and measures of the shipping country or of the United States; the purchase price of each item in the currency of purchase; all charges upon the goods itemised by name and amount; and the country of origin.
For research peptides the "detailed description" is where most problems start. A line reading "peptides" or a catalogue code does not describe the goods. A line that gives the compound name, the quantity per vial as labelled, the number of vials, the physical form (lyophilised powder) and the stated use (laboratory research) does. The description should agree word for word with the research-use declaration, the safety data sheet and the certificate, because a customs officer who finds three documents describing the goods three ways has a reason to hold the consignment.
The research-use declaration
A research-use declaration is a short statement, on the invoice or as a separate signed letter, that the material is supplied for laboratory research use only and is not for human or veterinary use. It names the goods, the lot numbers where possible, the consignee, and the capacity in which the consignee receives them. It is not a licence and it does not by itself determine how an authority will classify or treat the goods. What it does is put the exporter's and the importer's account of the material on the record, in the same words that appear on the labels and in the catalogue. Research use only explained covers what that phrase commits a buyer to inside the laboratory.
How classification works
Goods crossing a border are classified under the Harmonized System, maintained by the World Customs Organization. The WCO describes it as comprising more than 5,000 commodity groups, each identified by a six-digit code and arranged in a legal and logical structure with defined rules for uniform classification; more than 200 countries and economies use it as the basis of their customs tariffs and trade statistics, and about 98% of merchandise in international trade is classified under it. Each country extends the six digits with further digits of its own. In the United States that extension is the Harmonized Tariff Schedule, published by the International Trade Commission at hts.usitc.gov, which carries ten-digit lines.
The classification is assigned by the importer of record, in practice by the broker, and declared on the entry. It is not assigned by the exporter and it is not something a supplier can promise. The same material can be classified differently depending on its form, its declared use and the national schedule it is entered under, and CBP operates a binding ruling programme for importers who want a classification settled in advance. This guide does not state a tariff code for research peptides as a fact, because the code for any shipment is the importer's declaration and the authority's acceptance of it, not a property of the goods.
Holds, examinations and the cold chain
A consignment can be held for document review, for physical examination, or for sampling. FDA's import programme describes examination and sample collection as a stage of its process, and allows importers to check entry status and submit documents electronically through its ITACS system. FDA also publishes import alerts, which it describes as a tool used against products with a history of known violations; a product covered by an alert may be subject to detention without physical examination, meaning future shipments are detained without being tested or examined unless the importer can show the product is not within the alert.
For a laboratory the practical consequence of any hold is time at an uncontrolled temperature. A lyophilised peptide tolerates that better than a solution does, but the shipper's cold-chain design has to assume a hold of days rather than hours when a border is involved, and the data logger has to keep recording through it. Cold chain for peptide shipments covers how that is built, and temperature excursions on arrival covers how to read the logger output and decide what an excursion means for the lot. Where a hold has occurred, the logger file is part of the import record, not only the receiving record.
Receiving an imported consignment
- Count cartons against the air waybill, then vials against the packing list, then lots against the certificates. Three counts, three documents.
- Read the temperature logger before anything is put away, and note the dates of any hold against the excursion.
- Check the description on the invoice against the labels. A mismatch found now is a correction; found at audit it is a finding.
- File the entry summary, or the broker's confirmation of it, with the rest of the purchase record.
What to keep, and for how long
The import file for a consignment is the commercial invoice, the packing list, the research-use declaration, the safety data sheet, the certificates of analysis for each lot, the entry documentation with its classification and declared value, the carrier's documents, and the temperature record. CBP's guidance places responsibility for the correctness of the entry on the importer of record, and the importer is the party expected to produce the file if asked. Records to keep for research purchases covers the retention period and the filing structure that the rest of the purchase record uses; the import documents sit in the same folder, under the same lot numbers.
A buyer auditing a supplier that imports should expect to see the same file, redacted for price if necessary, for the lots being offered. A supplier who cannot produce an import record for imported stock has a gap in traceability, whatever the certificate says.
In short
Describe the goods the same way on every document. Let the broker classify, and keep the classification. Design the cold chain for a hold. Keep the whole file, under the lot numbers, with the certificates. All material in this catalogue is supplied for laboratory research use only, and ships within the United States.
