Frequently Asked Questions

Yes. Every tool on SellHandy currently offers a free version — no login, no usage caps, no paywall on the core features. The free tier is here to stay, so you can always run quick, reliable checks without a subscription.

We may introduce an optional paid (Pro) plan in the future for advanced features — think bulk calculations, saved projects, or team access — but the everyday calculators will remain free to use.

No account, no login, no email required. You open a tool and start calculating right away. Because nothing is saved on our side, there's nothing to sign up for.

SellHandy is built for e-commerce and foreign-trade shippers — the people who move products from a factory to a customer. That includes Amazon FBA and Shopify sellers, DTC brands, and cross-border importers and exporters who need to size orders, estimate shipping, classify goods, and check margins before they commit real money.

Six, and they're all free:

• MOQ Calculator — work out whether a supplier's minimum order quantity is actually worth it.
• CBM Calculator — convert cartons to cubic meters and see how they fit in a shipping container.
• Volumetric Weight Calculator — compare chargeable vs actual weight for air freight and estimate the freight cost.
• HS Code Lookup — find the right tariff code and see indicative duty across six destinations.
• Import Duty Calculator — estimate duty and VAT/GST by HS code, with a landed-cost breakdown.
• Profit Margin Calculator — see your true net margin after marketplace and fulfilment fees, including a US FBA fee estimate.

The calculators are built for planning and ballpark estimates, not for customs clearance or accounting. They use transparent formulas and 2026 indicative rates where applicable. Always double-check critical figures — especially duty and taxes — against the official source or a licensed broker before you ship a container or price a product.

Yes. Every calculator runs entirely in your browser. The numbers you type — prices, quantities, weights, supplier quotes — never leave your device and are discarded when you reload or close the page. We don't run an account system and we don't store your inputs on any server. (You can read the full details in our Privacy Policy.)

The duty and HS tools cover six major destinations: the United States, European Union, United Kingdom, Australia, Canada, and Japan. The Profit Margin tool's fulfilment-fee estimator uses US Amazon FBA (2026 non-peak, non-apparel) rates. Other channels — Shopify, eBay, your own store — can be modelled with the manual fee inputs.

They are indicative MFN (most-favoured-nation) rates for common classifications — a planning reference, not a legal ruling. Note that some categories, including Canada and Japan, have not been individually verified against the official 2026 tariff schedules; treat them as indicative and confirm on the official source. Trade-agreement reductions, anti-dumping duties and product-specific rules are excluded. SellHandy is not a customs broker.

No. We provide self-service calculators, not professional advice. For binding classifications, duty determinations, or tax questions, consult the official tariff (for example hts.usitc.gov for the US or tariffnumber.com for the EU) or a licensed customs broker / tax professional.

Yes. The site is fully responsive, so you can run any calculator from your phone while you're at a trade show or negotiating with a supplier.

We refresh rates and logic periodically and reference the 2026 schedules where available. Because duty, VAT and fulfilment fees change, re-run the calculators for the latest figures rather than relying on a saved screenshot.

Absolutely. Feel free to link to any tool from your blog, course, or internal docs. If you'd like to embed a tool on your own site, get in touch and we'll see what's possible.
