# Shopify Customs & HS Code Guides for Merchants — Origova > Plain-English guides for Shopify merchants shipping internationally: HS codes, country of origin, customs errors, and honest tool comparisons. Canonical: https://origova.com/guides --- # Customs and catalog guides for Shopify sellers Everything here is written for one reader: a Shopify merchant who ships (or wants to ship) internationally and keeps running into customs fields Shopify never explains. Plain English, no broker jargon, and always honest about the one thing no tool can do for you — the classification call is yours. New guides are added regularly; the newsletter below is the easiest way to catch them. ## Fundamentals Guide ### [What is an HS code?](https://origova.com/what-is-an-hs-code) The Harmonized System explained in plain English — what each digit means, HS vs HTS vs tariff codes, and how many digits you actually need.

Guide ### [Landed cost, explained](https://origova.com/landed-cost-for-shopify-sellers) The all-in cost formula, a worked example, DDU vs DDP — and why every calculation starts with your product data. ## Shopify how-tos Guide ### [Shopify customs information](https://origova.com/shopify-customs-information) What the customs fields are, where they hide in the admin, and how to bulk-edit them. Guide ### [Bulk HS codes in Shopify](https://origova.com/bulk-edit-hs-codes-shopify) The bulk editor reaches HS codes but won't tell you which products are missing one.

Guide ### [Find products missing HS codes](https://origova.com/find-products-missing-hs-codes-shopify) Shopify has no report for this.

Guide ### [HS code automation for large catalogs](https://origova.com/hs-code-automation-large-catalogs) 500–10,000 SKUs: what's fully automatable, where judgment stays human, and the realistic workflow step by step.

Guide ### [Prepare for the new US customs rules](https://origova.com/prepare-shopify-store-us-customs-rules) The six-step checklist: audit, classify, set origins, choose DDU or DDP, verify carrier paperwork, keep it synced. Guide ### [Catalog optimization for cross-border](https://origova.com/product-catalog-optimization-cross-border) The six fields customs reads, why the data decays, and the measure-fix-export-sync loop that keeps a catalog clean. ## Comparisons Comparison ### [Origova vs Zonos](https://origova.com/origova-vs-zonos) One collects duties at checkout from $2,500/year; one fixes the customs data underneath for $7.99/month.
