Easyship Duty Calculator API Alternative for Ecommerce

GingerControl's Classification + Tariff Calculation API is a REST API for enterprise systems: your booking service posts a description and an origin and gets back a 10-digit HTS code, the general and special rates, and one list per duty layer (Section 301, Section 232 metals, other Chapter 99 lines). The difference from Easyship is where classification happens: inside the same call, not before it. It starts with one call to size your key, and while you evaluate, the free Policy Briefings email you when a U.S. trade rule changes. I'm Chen Cui, co-founder; we designed this API's duty stack, so read my scores with that in mind.

What are the alternatives to the Easyship duty calculator API for a carrier?

The main alternatives are GingerControl's Classification + Tariff Calculation API, Zonos Landed Cost with Zonos Classify, Avalara AvaTax Cross-Border, Hurricane Commerce's Kona API, SimplyDuty and Dutify, and for a carrier whose shippers send descriptions instead of codes, GingerControl ranks first because one call returns the 10-digit HTS code and each U.S. duty layer per item. The carrier-run landed cost APIs from DHL and UPS are covered further down, outside the scores.

Evaluate landed cost calculation API coverage by the cost components returned, not by whether the vendor uses the term landed cost.

How we scored: GingerControl's editorial scores, October 2026, on a 5-point scale; they are our judgement, not sourced data. U.S. duty layer detail asks whether each item comes back with its base rate and each Chapter 99 line apart (what one call returns). 10-digit U.S. classification asks whether the API itself returns the code a U.S. entry needs (Classification Researcher). Composite and split-code goods asks whether goods dutied part by part, such as Chapter 91 watches, come back as components (API reference). Batch integration covers batching, per-item status and fit with a booking or manifest flow. Easyship, the API this post replaces, scores 2.6, 2.9, 2.6 and 3.5, overall 2.9. Prices were read on each vendor's own pages on October 10, 2026. Left out on purpose: destinations beyond the U.S., VAT and GST, and checkout DDP, where Zonos, Avalara and Easyship cover far more than GingerControl, which does none of them.

Bottom line: For a carrier booking about 20,000 U.S. parcels a day from shipper lines like "phone case x3, charger x1", GingerControl's API is the pick, because the code and every U.S. duty layer come back in the same call. If you need guaranteed duties and taxes at a merchant's checkout, or destinations beyond the U.S., Zonos or Avalara fit better, and Easyship stays the simplest choice for shippers already on its platform with HS codes in hand.

This post is not about adding a duty and tax calculator to a Shopify store; that is the Shopify duty and tax calculator API guide. It is not about a national post's 100,000-parcels-a-day pipeline either: see Bulk HTS + Tariff API for Postal Parcel Operators. For checkout DDP workflows, see Real-Time DDP at Checkout.

For a 3PL handling multiple client catalogs, 3PL HTS classification API for bulk imports covers the batch input and review workflow.

How does the Easyship duty calculator work?

Easyship's duty calculator comes in two forms: a free web Import Duty Calculator that estimates tax and duties from a shipment's value and product type for 220+ destinations, and a paid taxes_and_duties API endpoint that calculates duty and tax per item once you send an HS code ^{[1] [2]}. Easyship also puts a free HS code lookup tool in its shipping dashboard, and sells a separate HS Code API that lists HS codes and filters them by description ^{[1] [2] [3]}.

I read Easyship's API reference (version 2024-09, page updated June 18, 2026) on October 10, 2026. This is what the endpoint takes and returns:

Credit where it is due: Easyship returns money amounts in a currency, separates duty from tax, and lists additional rates apart from the base rate, all for 220+ countries and territories ^{[2] [4]}. GingerControl's API returns rates and Chapter 99 headings for U.S. imports only, and your system does the multiplication.

Easyship's included Tax & Duty calls top out at 2,500 a month on its largest self-serve plan, an eighth of what this carrier books in one day; after the allowance, each call is billed at US$0.09 to US$0.11 depending on the plan, and volume above 10,000 shipments a month falls under Easyship's quote-based Enterprise plan ^[3].

Plus (US$29)125 calls

Premier (US$69)625 calls

Scale 1 (US$99)1,250 calls

Scale 2 (US$149)1,875 calls

Scale 3 (US$199)2,500 calls

Source: Easyship plans page and its February 2026 U.S. plan pricing sheet, read October 10, 2026

See the data

Easyship plan	Included Tax & Duty calls a month
Plus (US$29)	125 calls
Premier (US$69)	625 calls
Scale 1 (US$99)	1,250 calls
Scale 2 (US$149)	1,875 calls
Scale 3 (US$199)	2,500 calls

Two cautions for a carrier like this one. First, Easyship says "Plan inclusions and pricing may vary by country", so the U.S. sheet above may not be your price ^[3]. Second, the same limits page that is dated June 10, 2025 lists the endpoint at "100 requests per day and 3,000 requests per month". I could not confirm whether that still applies under the February 2026 plans, so ask Easyship before you plan 20,000 parcels a day on it ^[5].

Does the Easyship duty API need an HS code first?

Yes: Easyship's taxes_and_duties endpoint marks hs_code as required on every item, either 8 digits ending in 00 or a 10-digit regional code, so the code has to exist before the duty does ^[2]. Easyship's own answer to that is a second product, the HS Code API, which lists HS codes you can filter by description, at US$0.03 to US$0.05 a call on the U.S. plans ^{[2] [3]}. That makes the Easyship pattern a lookup per line, a choice from the list, then a calculation per shipment.

The APIs in this post split on exactly that point. Here is what each one asks for before it returns duty, from each vendor's own pages read October 10, 2026:

Quotable insight: A duty quote for a parcel is the last of three answers, not the first: what each item is (a 10-digit code), where it was made (not where it shipped from), and what that line is worth. A calculator API that takes the code as input hands the hardest answer to a shipper who typed "phone case x3, charger x1". At 20,000 parcels a day and two lines each, that is 40,000 classification decisions hiding inside 20,000 duty quotes.

Since the U.S. suspended de minimis for every country, there is no longer a value under which a commercial parcel skips this. CBP made the suspension indefinite for both non-postal shipments and mail from June 24, 2026; the new mail entry procedure took effect July 24, and the statutory repeal takes effect July 1, 2027 ^{[6] [7]}.

The de minimis repeal impact on small importers guide shows how per-parcel filing and processing change a small seller's cost model.

Is the Easyship calculator accurate for U.S. duty?

Easyship publishes no accuracy figure and no duty guarantee on its tax and duty pages, so for U.S. duty its estimate is as accurate as the HS code and origin you send and the rate types it supports, which its docs say exclude non-percentage duty tariffs ^{[2] [5]}. That last point matters for U.S. parcels: the HTS also has specific and compound rates, and the July 2026 Section 301 notice has to spell out how to convert them to an ad valorem equivalent for the five economies with a combined cap ^[8].

For a U.S. parcel entered in October 2026, one item's duty can carry all of these layers, and each one depends on the code and the country of origin:

A single duty number hides all of that, and the entry does not: CBP's July 2026 filing guidance has the Section 301 Chapter 99 heading reported first, then Section 232, each on the entry line ^[10]. When Jet Import Brokers, a U.S. customs broker, tried several well-known tariff tools before working with us, some returned wrong or incomplete rates: conditional exemptions were missing and watches returned error codes ^[13]. The case names no vendor, and neither do I.

For billing, the honest framing for any of these APIs, ours included, is an estimate for planning and quoting. The broker files the entry and CBP sets the final duty at liquidation. Store the code, the origin and each duty line with the booking, so a shipper's dispute can be traced to the input that caused it.

How do you add U.S. duty per item to the booking flow before the label prints?

Call the classification and duty API from your server when the shipper books, send every line of the parcel as its own item with your own item_id and its country of origin, multiply each returned rate by that line's customs value, and print the label only once every line comes back with a status of ok.

The call sits between the booking form and the label, and the code it returns travels with the booking from then on:

1. Shipper booksDescription, quantity, value and made-in country per line
2. Batch the linesUp to 120 items per call by default, each with your item_id
3. Code and layers come back10-digit HTS code, general and special rates, Section 301 and 232 lists
4. Apply rates to valueYour system computes duty per line and per parcel
5. Label printsCode and Chapter 99 lines stored with the booking

What the request looks like for the two-line parcel, using the batch endpoint and field names in our API reference ^[14]:

{
  "items": [
    { "item_id": "BKG-20261010-0001-1", "description": "Silicone phone case for smartphone, pack of 3", "country_of_origin": "CN" },
    { "item_id": "BKG-20261010-0001-2", "description": "USB wall charger, 20 W, plug-in", "country_of_origin": "CN" }
  ]
}

The details that decide whether this works at 20,000 parcels a day:

• Keep the key on your server. The API manual says never to put the key in front-end or browser code, or anywhere end users can reach, so the shipper app calls your backend, and your backend calls the API ^[14].
• Send origin per line, as made-in. The country_of_origin field is where the goods were made, not where the parcel ships from (the FAQ on this page covers the Malaysia and China case) ^[15].
• Expect per-item status. Results come back in the order you sent them, each with ok or failed, and a failed line (for example classification_failed) does not fail the batch. Route failed lines to a person instead of blocking the whole parcel ^[14].
• Count items as well as calls. At two lines per parcel, 20,000 parcels is 40,000 items, or 334 batch calls of 120. Quota is counted per item, and we size each key to the customer's calling pattern, IP allowlist and peak QPS. Over the rate limit or the item quota, the API answers 429 with a Retry-After header. I give no speed figure because our manual publishes none ^[14].
• Check the informal-entry line with your broker. 19 CFR 143.21(a) lets shipments up to US$2,500 enter informally, except articles valued over US$250 classified in Chapter 99, subchapters III and IV. DHS suspended that exception "until further notice" in its September 2, 2025 de minimis notice, and CBP's October 8, 2026 proposed rule on low-value shipments would delete it, so confirm which entry type a parcel with Chapter 99 lines needs ^[16].

How does GingerControl's Classification + Tariff Calculation API differ from Easyship's?

GingerControl's API classifies and returns U.S. duty layers in one call from a description and an origin, for U.S. imports only, while Easyship's endpoint calculates duty and tax amounts for 220+ countries and territories once you supply the code.

Bottom line: For a carrier whose shippers type descriptions for about 20,000 U.S. parcels a day, GingerControl's API removes the code lookup and returns each U.S. duty layer per line. For a shipper already on Easyship with HS codes in hand and parcels bound for many countries, Easyship returns finished duty and tax amounts, which GingerControl does not.

The code inside the call comes from the Quick line of GingerControl's classification engine, which scored 99.86% at the 10-digit level on GingerControl's own internal test of 1,000+ products; that is our test, not an independent benchmark.

GingerControl's Classification Researcher follows the reasoning a licensed customs broker uses: GRI analysis, Section and Chapter Note review, and CROSS ruling research. Its classifications are for general reference, educational, and planning purposes; before a code goes on an entry, your licensed customs broker reviews it. GingerControl is not a customs broker, does not file entries, and does not give legal advice. The same goes for every code the API returns.

In the app, the Classification Researcher asks before it decides ("Ginger doesn't guess. It asks."); the API is built for volume and returns a code and a status per item, so plan a review step for lines whose descriptions are too thin to classify.

What GingerControl does not do, so you can plan around it: no VAT, GST or sales tax, no duty for destinations outside the U.S., no checkout DDP, no AD/CVD computation, no entry filing and no export control classification by API. A carrier that also ships to the UK or the EU needs a second source for those lanes. There, classifying an item and calculating its VAT are separate jobs, and one wrong code changes both the duty and the import tax on the same parcel line; what HS code classification and VAT calculation software must do sets the two jobs apart and works through that case.

Which other duty and tax APIs did I check, and where does each fit?

Zonos fits merchant checkouts, Avalara fits sellers already on AvaTax, Hurricane Commerce fits teams that want classification and multi-country duty from one vendor, SimplyDuty and Dutify fit low volumes, and DHL's MyDHL API fits shipments on DHL's own network. I read each vendor's own pricing, product and developer pages on October 10, 2026 and ran no test shipments through them, so everything below is what their pages state.

Zonos Landed Cost and Classify

Zonos is a cross-border landed cost platform with a GraphQL API and a documented REST call (POST /v1/landed_cost), covering "217 countries and territories" in its docs ^[17]. Its landed cost guarantee is priced at US$2 plus 10% of duties, taxes and fees per order, "typically paid for by the shopper at the time of checkout", and Classify starts at US$500, US$1,000 or US$1,250 a month, with 1,000 free classifications (10,000 a year for Zonos Platform users) ^[17]. It does well what a merchant's checkout needs: a guaranteed number, tax filing for several regimes, and Classify, which Zonos says processes up to 50,000 items an hour. Its use case ends at the merchant's order: the fee is built around a shopper's checkout, not a carrier's booking. Best for merchants and platforms that need guaranteed duties and taxes at checkout; the head-to-head is in Zonos API vs GingerControl API.

For a BigCommerce storefront, the BigCommerce tariff API integration guide places classification and duty calls in the catalog and checkout flow.

Avalara AvaTax Cross-Border

Avalara AvaTax Cross-Border "calculates and estimates customs duties and import taxes in real time", sits beside Avalara's sales tax products, and has a separate Tariff Code Classification product that covers "more than 180 countries" with "260+ classifiers" ^[18]. Price is quote-based, and Avalara states no accuracy percentage. It does well what a seller already on AvaTax wants: one vendor for sales tax and import tax. Its use case ends where a request has no HS code: Avalara's FAQ says real-time calculation needs one, and the estimated mode applies only to new transactions ^[18]. Best for sellers already running AvaTax; more in our Avalara Cross-Border alternative guide.

Hurricane Commerce Kona API

Hurricane Commerce's Kona API offers "HS Classification for 10 digits and beyond" plus duty and tax calculation, by direct API or through the Hurricane Portal without integration ^[19]. Pricing is not public. Its strength is the one-vendor job of classification plus multi-country duty and tax. Its page says Hurricane has been "the most accurate time and time again in side-by-side tests" without publishing the test data there, so ask for it. Best for teams that want classification and multi-country duty and tax from one vendor.

SimplyDuty and Dutify

SimplyDuty, run by ParcelWorks Limited in the UK, sells its classification and duty APIs at £0.10 a call or £9.99 (100 calls) to £499.99 (5,000 calls) a month, though most of its pages are dated 2019 to 2025 ^[20]. Dutify charges US$15, US$75 or US$149 a month, with the API on the US$75 and US$149 plans and 5,000 calculations a month at the top ^[20]. Both publish prices a small team can budget against, and both top out at 5,000 a month on their published plans, a quarter of this carrier's single day. Best for low-volume lookups; the per-call math across vendors is in our duty and tax API pricing comparison, and SimplyDuty vs GingerControl covers the calculator side.

DHL and UPS landed cost APIs

DHL Express's MyDHL API returns an "estimated Landed Cost which includes Duties & Taxes", is "solely offered to business customers", needs "an active customer account with DHL Express" and needs your items' HS codes; DHL eCommerce Americas also has a Duty & Tax API that requires an hsCode ^[21]. UPS lists a Landed Cost Quote API that estimates duties, VAT, taxes, brokerage and other fees, which I could confirm only through search results because its developer pages timed out ^[21]. I could not open FedEx's or Royal Mail's own pages for this post, so I leave them out. DHL's API fits shipments moving on DHL's own network; a carrier with its own network needs its own duty source. I left them out of the scored table, since the DHL API requires a DHL Express account and I could not read UPS's pages directly.

By the numbers

• June 24, 2026: CBP's two interim final rules (Dec. 26-12 and 26-13) made the de minimis suspension indefinite for non-postal shipments and mail on that date; the new mail procedure began July 24, and the statutory repeal takes effect July 1, 2027 ^{[6] [7]}.
• 10% and 12.5%: the forced-labor Section 301 rates on goods entered from July 24, 2026: 10% on 17 economies, Malaysia, Indonesia and Cambodia among them; 12.5% on 38 others, China among them ^[8].
• 50%: the Section 232 rate on Annex I-A steel and aluminum articles, charged on the full customs value since April 6, 2026 ^[11].
• US$1.38 per waybill: the express consignment carrier facility fee per individual waybill from October 1, 2026; formal entries pay a merchandise processing fee of 0.3464%, with a US$34.58 minimum and a US$670.86 maximum ^[12].
• US$216.7 billion: total duty, taxes and fees CBP collected in fiscal year 2025, the latest full year on CBP's trade statistics page (updated July 27, 2026) ^[22].
• 2,500 calls a month: the Tax & Duty API allowance on Easyship's largest self-serve U.S. plan, Scale 3 at US$199, then US$0.09 a call (February 2026 sheet) ^[3].
• 1,000 free classifications: Zonos Classify's free tier (10,000 a year for Zonos Platform users), with paid plans from US$500 a month (read October 10, 2026) ^[17].
• Revision 21: the 2026 HTS revision in effect since October 9, 2026; Revision 20 lasted from September 28 to October 9, so a cached duty table goes stale in weeks ^[9].

Which option fits which carrier situation?

The right API depends on what your shippers send and where their parcels go: descriptions for U.S.-bound parcels point to GingerControl's API, and HS codes for many destinations point to Easyship or Zonos.

The tiered answer: if your parcels are U.S.-bound and arrive as descriptions, start with GingerControl's API. If they go to many countries with codes already attached, Easyship or Zonos covers more ground, and Zonos is the better pick when the number must be guaranteed at a checkout. If the buyer is a store on AvaTax, Avalara wins on bundling. If your volume is a few thousand lookups a month, SimplyDuty or Dutify publish prices you can start on today.

Wiring code and duty into your booking flow

Your shippers will keep typing "phone case x3, charger x1", and every one of those lines now needs a U.S. code and duty before the label prints. GingerControl's Classification + Tariff Calculation API turns each line and its country of origin into a 10-digit HTS code and its U.S. duty layers in one call, 120 items per call by default, with a key sized to your booking pattern after one call. See what one call returns for each parcel line. If you would rather talk through your manifest first, book the call that sizes your key.
