Step-by-step explanation
Identify the document by its job and fields, not by one label.
Lista de empaque, lista de bultos, lista de contenido and packing list can identify an export package inventory, but the same words can also appear on a domestic packing slip or a non-commercial checklist. A true export packing list normally maps the shipment to packages and their contents, marks, counts, weights or dimensions. A commercial invoice records the sale and values; a bill of lading or air waybill is a transport document; a certificate of origin addresses origin; and a customs declaration records regulatory filing data. Read the complete title, parties, references, table headings and footer before choosing Packing List, and keep every companion document on a separate manifest and quote line.
Original fictional example: the secure upload contains “Lista de empaque LE-184” with pallet and carton rows, a separate “Factura comercial FC-184,” and an air waybill. The manifest records three different sources. The English translation does not merge their fields or rename all three as shipping lists.
01
Inventory the title, pages, continuation sheets and active version.
Record the complete non-sensitive title, issuer or preparer, packing-list number, issue or shipment date, page x of y, continuation labels, revision, amendment or replacement wording and every attachment. Keep filenames separate from printed controls. If two versions or page counts conflict, pause and ask which complete set is active rather than combining the clearest pages from each.
Original fictional example: “LE-184 Rev. 2, page 1 of 4” arrives with a two-page draft marked “Preliminar.” The manifest keeps the four-page revision as one candidate set and the draft separately until the customer confirms scope.
02
Map every party role and shipment reference.
Preserve seller, exporter, shipper or consignor, buyer, importer, consignee, notify party, carrier and freight-forwarder labels exactly as the source assigns them. Keep company names and addresses attached to the correct roles. Copy packing-list, invoice, purchase-order, sales-order, shipment, container, seal, tracking, air-waybill and bill-of-lading references character for character. Do not collapse different roles because one company fills several blocks.
Original fictional example: “Expedidor: Taller Norte” and “Vendedor: Grupo Río” appear above invoice “FC-184” and PO “PO-7710.” The English blocks retain Shipper and Seller separately and keep both references intact.
03
Preserve the pallet, crate, carton and inner-package hierarchy.
Identify every printed package level and keep its parent-child relationship visible. A pallet may contain cartons, and a carton may contain trays, bags or pieces; the total package count may therefore refer to one level rather than every physical unit. Preserve package type, sequence, count, container or seal reference and “of” relationships. Do not flatten nested packaging or invent a hierarchy from spacing alone.
Original fictional example: “Pallet 2: cartons 11–18; 24 units per carton” remains one pallet containing eight numbered cartons, not nine packages at one level and not 192 loose units.
04
Keep marks, numbers and item-to-package rows traceable.
Reproduce package marks, case numbers, item or line numbers, SKU or part numbers, lot or batch identifiers and serial ranges in their exact columns. Translate descriptive goods text consistently while preserving models, grades and identifiers. Keep each quantity and unit of measure attached to the correct package and item row. A blank cell, ditto mark, dash and zero are different source states; do not silently repeat, delete or fill them.
Original fictional example: carton “C-07” lists part “AX-4,” lot “L2609,” quantity “12 pzas”; carton “C-08” repeats AX-4 but leaves lot blank. The English table preserves 12 pcs in C-07 and the blank lot in C-08.
05
Control net, tare and gross weights, dimensions and volume.
Keep net weight, tare and gross weight as separate labeled values at package and shipment level. Preserve length, width, height, cubic volume and every printed unit, decimal, sign and separator. If an approved English style changes a decimal comma to a point, verify each digit and keep grouping unambiguous. Do not convert kilograms to pounds, centimetres to inches, calculate volume, derive tare or force printed totals to equal row sums.
Original fictional example: “Peso neto 248,60 kg; tara 18,40 kg; peso bruto 267,00 kg; 120 × 80 × 95 cm” becomes the same four labeled values under the documented separator style, with no imperial conversion.
06
Compare companion references without silently harmonizing them.
Use a controlled cross-document check for identifiers that the packing list repeats from a supplied invoice, purchase order, transport record or certificate. Record exact matches and flag missing digits, different dates, package totals or descriptions for the customer or shipment owner. Translate each source as printed until an authorized correction or replacement source is provided. The translator does not decide which record controls, amend a shipping document or certify factual consistency.
Original fictional example: the packing list shows invoice “FC-184” and 18 cartons, while the supplied invoice shows “FC-148” and 16 cartons. QA raises two source queries and preserves both originals; it does not choose the matching-looking number.
07
Preserve notes, visible marks, approvals and final page controls.
Translate handling notes, packaging instructions and qualifying statements or caveats visible in the source without converting them into new shipping directions. Represent legible stamp text, signature-role labels and visible signatures using the approved treatment. Keep footnotes, repeated headers, continuation links, page numbers, revision controls and totals visible. Finish with row-by-row, package-by-package and page-by-page bilingual QA against one confirmed source set, including a separate reference check for every repeated identifier.
Original fictional example: the final page states “Continuación de LE-184,” carries a “Revisado por Logística” signature block and says “No apilar.” The translation keeps the continuation reference, reviewer role and note; it does not add a handling symbol or confirm that the instruction was followed.
