  • Print or save one test preview before using the template in production.

Common failure

  • Trying to print item-level customs data outside the line item loop.
  • Missing HS code or origin values on some variants.
  • Using product-level origin when the same product has variants manufactured in different countries.

Use case

When to use this tool

Best for cross-border merchants preparing document templates that need item-level customs data in a printable layout.

Focuses on item-level product and variant data.

Covers HS code, country of origin, customs description, item quantity, and origin-sensitive variant data.

Identifies EORI, tax ID, or exporter notes as document-level fields that usually belong near the header or seller details.

Explains when product metafields are enough and when variant metafields are safer for customs values.

Uses cautious customs language and clear testing steps.

Connects naturally to metafield and packing slip workflows.

Free tool fit

Use the snippet when the edit is narrow.

Generate item-level metafield snippets for HS code, country of origin, or customs description.

  • You know which Shopify Order Printer template you want to edit.
  • You can test in a duplicate template before touching the live one.
  • The field or layout change maps to the Liquid objects listed on this page.

Manual fix fit

Request help when placement is risky.

Request a custom commercial invoice layout with merchant-reviewed customs fields.

  • Your current template already has custom loops, tables, CSS, or app-specific fields.
  • The snippet works in isolation but prints blank, repeats, or breaks layout in your real template.
  • The document is customer-facing, B2B, VAT, customs, or warehouse-critical and needs careful test notes.

Install steps

Copy into Shopify Order Printer carefully.

The preview uses sample data. Always test the template with real orders before using it for fulfillment, accounting, customs, or customer-facing documents.

  1. Step Store HS code, country of origin, or customs description as product or variant metafields.
  2. Step Use variant metafields when customs values differ by size, material, color, kit, or manufacturing country.
  3. Step Keep EORI, exporter registration, tax ID, and merchant declaration notes near the commercial invoice header or footer.
  4. Step Generate one field block at a time and place it inside the item loop.
  5. Step Preview orders with multiple countries, variants, and missing customs fields.
  6. Step Check that the printed item title, customs description, quantity, HS code, origin, and destination country all match the shipment.
  7. Step Verify the document with your carrier, broker, or customs workflow before shipping.

Problem diagnosis

Match the symptom before changing Liquid.

Use these checks to decide whether the issue is field data, snippet placement, print settings, or a template merge problem.

HS code or origin prints once instead of per product.

Likely cause
The customs block was placed in the document header or footer rather than inside the commercial invoice item table.
Fix
Paste item-level customs fields inside the line item loop, beside title, quantity, customs description, HS code, and origin.

Some invoice rows show missing customs values.

Likely cause
Not every product or variant in the test order has HS code, origin, or customs description metafields filled in.
Fix
Fill the source metafields for each product or variant, then preview orders with mixed and missing data before shipping.

Every variant prints the same origin or HS code.

Likely cause
The template reads product metafields even though customs data differs by variant, material, supplier, kit, or manufacturing country.
Fix
Move variable customs values to variant metafields and use line_item.variant.metafields.custom.field_key.value.

The commercial invoice is hard for staff to review.

Likely cause
Customs fields are separated from item title, quantity, destination country, or carrier-facing description.
Fix
Keep customs description, quantity, HS code, origin, and destination context together in the item table, then verify with the carrier workflow.

FAQ

Common Shopify Order Printer issues

Can I print HS codes from product metafields?

Yes. Generate a product metafield snippet and place it inside the line item loop.

Can this replace carrier customs forms?

No. It can help create a printable document template, but carrier and customs requirements still apply.

Should customs fields be product or variant metafields?

Use variant metafields if the value changes by variant; otherwise product metafields are usually simpler.

Where should an EORI number print?

EORI or exporter registration numbers usually belong near the seller, exporter, or commercial invoice header section, not repeated inside every item row.

What if my customs description is different from the product title?

Store a separate customs description metafield and print that value in the item table. Product titles are often too branded or too long for customs paperwork.

Can I split HS code into its own page later?

Yes. HS code and country of origin are strong enough long-tail topics to become separate pages if Search Console shows impressions.
