Shopify Markets Pro duties mismatch — checkout duties vs expected landed cost.

Several products can look like “international tax is wrong.” They do not share a fix. This page is only when Markets Pro / managed markets duties and import taxes show at checkout but the amount does not match the expected landed cost. Duties / import taxes / DDP entirely missing or $0 when you expect a line is duties / import taxes missing. Settings → Taxes overrides or product/collection tax settings that will not Save are tax overrides not saving. Wrong countries or rates on shipping profiles / zones are shipping profile zones wrong. This page is only: checkout duties amount ≠ expected landed cost under Markets Pro / managed markets.

Six ordinary reasons the numbers diverge: Markets Pro / managed markets duties on for the country but HS code or country of origin missing / wrong on the SKU; Incoterm mismatch (you quote DDP / landed cost, checkout or shipping still DAP); Markets duties settings or a duties app using a different classification than your landed-cost calculator; shipping profile / rate that changes whether duties are collected at checkout; currency / Markets price rounding that shifts the duties base; domestic sales tax / tax override bugs mistaken for import duties. Walk them in that order. You already pay for Shopify Admin. You do not need another SaaS to prove why the duties line disagrees with landed cost.

Open Settings → Markets and Taxes and duties. Capture: Markets Pro or managed markets enabled for the buyer country; duties / import taxes collection on or off; any duties app in play. On the product, capture HS code and country of origin. Write down the landed-cost estimate you expected (product + shipping + duties + import taxes) vs the checkout Duties / Estimated duties line for the same country and cart.

Side-by-side in a private window: same SKU, same destination country, same shipping method. Screenshot checkout duties before and after you change HS / origin or Markets duties settings. If duties are entirely missing or $0 when you expect a line, leave this page and use duties / import taxes missing. If Admin tax overrides will not Save or product Charge tax settings revert, open tax overrides not saving. If the wrong country or rate is on the shipping profile / zone (not the duties line), open shipping profile zones wrong.

Align the Markets Pro / managed markets → HS / origin → Incoterm (DDP vs DAP) → shipping profile → checkout proof chain: correct HS codes and country of origin on the SKUs in the cart; confirm duties collection is enabled for that market; sell the Incoterm you quote (DDP / duties at checkout vs DAP / duties unpaid); ensure the shipping profile / rate for that country matches the landed-cost path; hard-refresh a private-window checkout to the same destination. Do not paste a domestic tax override and expect Markets Pro duties to match your landed-cost sheet.

Retest with the same cart and country (private window). If duties still mismatch, compare the duties base (product price in market currency, shipping included or not) against your calculator. Related entirely-missing duties: duties / import taxes missing. Related domestic sales tax wrong: tax wrong at checkout. Related Markets price / currency wrong: Markets currency wrong.

Checklist: (1) screenshot Settings → Markets showing Markets Pro / managed markets for the buyer country, (2) confirm Taxes and duties collection is on for that market, (3) confirm product HS codes and country of origin, (4) confirm Incoterm / shipping profile matches DDP vs DAP you sell, (5) hard-refresh a private-window checkout and compare Duties line to expected landed cost, (6) if duties are missing, overrides will not Save, or zones are wrong, switch playbooks.

Prove it: Markets Pro / managed markets duties are on; HS / origin are correct; checkout Duties / import taxes match the landed-cost estimate for the same cart and country; missing duties / tax override / shipping zones stay independent. If Admin Markets looks correct but duties never appear, open duties / import taxes missing.

Duties / import taxes / DDP entirely missing or $0 is duties / import taxes missing. Tax overrides / product or collection tax settings not saving is tax overrides not saving. Shipping profiles / zones wrong rates or countries is shipping profile zones wrong. Domestic sales tax wrong is tax wrong at checkout. Markets currency / price wrong is Markets currency wrong. None of those finish a Markets Pro duties mismatch where a duties line exists but disagrees with landed cost.

Finish prove Markets Pro / HS / origin / Incoterm → checkout duties vs landed cost proof first. Only then open the related playbook that matches the remaining symptom.

Stay DIY if you can spend one afternoon on the list above: prove Markets Pro / managed markets, HS / origin, and Incoterm; align checkout duties with landed cost; and stop treating missing duties / tax overrides / shipping zones as the same bug. That is the whole playbook. No agency required. Short answers also live on the merchant FAQ.

Pay for help when the work is not the Markets Pro toggle — it is connecting the stack you already have so lead capture is not dying in DMs, cart / ops exceptions land in a channel you already check, and the live store is one workflow instead of a spreadsheet plus a Slack bot you forgot. That is the Latch AI Ops install.

What $997 USD one-time buys: lead capture on the live store, ops alerts in a channel you already check, and a checkout-ready workflow. 72 hours after collaborator access, not after payment. One live Shopify store. Access plus a delivery thread. Store URL collected at checkout. Not a SaaS seat, not an upsell retainer, not a conversion guarantee, not a brand or theme job.

Other shops’ public ranges, not testimonials: a checkout / ops install typically runs $500–$2,500. A full ops consulting block typically runs $2,000–$5,000. $997 is the cheap end of that work, sold as a 72-hour install of three systems — not as an earnings number or uptime claim.

What it does not buy: more orders, automatic Plus eligibility, a custom duties calculator rewrite, or a case study. Latch AI Ops has not published customer proof because there are no customers yet. You are buying the install.
