Duty Tax API Pricing Compared: GingerControl, Zonos, Avalara

Normalize these offers with trade-compliance software pricing models before comparing an order fee, per-call charge and app-credit plan.

GingerControl's Classification + Tariff Calculation API, for enterprise systems, takes a product description and its origin and returns a 10-digit HTS code with its U.S. duty layers as JSON, 120 items per call by default, with split-code goods such as Chapter 91 watches returned as components. A team that does not need an API can work in the GingerLite app instead, $150 a month for 300 credits, and the fee math alone is in our free MPF and HMF calculator. I'm Chen Cui, co-founder; we designed this API's duty layers, so weigh my scores with that in mind. Every competitor price below, from Zonos, Avalara, Easyship, SimplyDuty, Dutify, Hurricane Commerce and Descartes to the classification prices of KYG Trade, HTS Hero and Tarifflo, was read on the vendor's own pages on October 10, 2026; we ran no lookups on any competitor's API. What the Zonos API returns for a logistics company is in Zonos API Alternative; this post compares what each vendor charges.

How does duty and tax API pricing work: per order, per call or per month?

Duty and tax API pricing works on three meters: per order (Zonos's guaranteed landed cost, $2 plus 10% of duties, taxes and fees), per call inside a monthly plan (Easyship, SimplyDuty and Dutify publish these), and no published price (Avalara, Hurricane Commerce and Descartes are quote-based; GingerControl's API is for enterprise customers only and starts with a call) ^{[1] [5] [7] [9] [10]}.

How we scored: These are GingerControl's editorial scores, October 2026, out of 5, not sourced data. Layer detail is each U.S. duty layer per item, by Chapter 99 heading (Classification + Tariff Calculation API); 10-digit classification is a U.S. 10-digit code from a product description (the reasoning behind ours is on the Classification Researcher page); composite goods is split-code and composite handling, such as Chapter 91 watches dutied part by part; batch integration is how many items one integration can send and track per call. If your clients run Avalara today, its overall is 3.7. We left out checkout DDP, VAT and GST, non-U.S. duty and published self-serve API pricing, because GingerControl does not do them; Zonos and Avalara lead there.

Bottom line: For a 3PL director of product finance budgeting about 3 million lookups a year for 250 importer and marketplace-seller clients, GingerControl's Classification + Tariff Calculation API fits the U.S. inbound side: a 10-digit code and each duty layer per item, with your key sized to your calling pattern after a call. Zonos is the better pick where merchants want duties and taxes guaranteed at checkout, and Avalara where clients already run AvaTax for sales tax.

The three meters measure different things, so a line in one vendor's price does not map onto a line in another's:

The unit worth paying for is one item's code and duty lines. On our own production run of the Tariff Calculator on October 6, 2026, one item, HTS 6402.99.9005 athletic shoes at $25,000 from China, came back as a 20% base rate ($5,000), 9903.88.15 at 7.5% ($1,875) and the forced-labor Section 301 line 9903.05.31 at 12.5% ($3,125), plus $117.85 in MPF and HMF ^[18]. The API returns the same kind of layers as JSON, and your system applies them to the customs value.

Quotable insight: Duty API prices only compare on one unit: a 10-digit code plus its duty lines for one item. A per-order fee prices a guarantee, a per-call fee prices a request that may carry one item or several lookups, and a batch quota counts items. For a 3PL budgeting 3 million lookups a year, convert every price into cost per item classified and cost per item dutied, kept apart, because a SKU is classified once and dutied on every entry.

What do Zonos, Avalara and Easyship charge at volume?

At 250,000 lookups a month, only Easyship and SimplyDuty publish a per-call price you can multiply out ($0.09 to $0.11 and £0.10 a call), Zonos publishes a per-order fee for guaranteed landed cost and Classify plans from $500 a month, and Avalara publishes no Cross-Border price at all ^{[1] [3] [5] [7] [9]}.

Sources: ^{[1] [3] [5] [7] [8] [9] [10] [11] [12] [16]}.

On Easyship's published U.S. prices, our worked example puts 250,000 Tax and Duty calls at $22,474 a month on the Scale 3 plan and $27,515.25 on Plus: the $199 plan fee is under 1% of the bill, so the per-call rate is what you are negotiating.

Free, pay as you go	$27,500
Premier, $69 a month	$25,006.50
Scale 3, $199 a month	$22,474

Read that list price as a ceiling for negotiation, not a quote. Easyship's plan sheet tops out at 10,000 shipments a month before Enterprise, "Contact Us", and its developer docs, last updated June 10, 2025, list a rate limit of 100 requests a day and 3,000 a month on the Tax and Duty endpoint; whether that limit still applies under the 2026 plans is not stated, so ask ^{[7] [8]}. The call also needs an 8- or 10-digit HS code you already have, so classification is a second meter.

Zonos's per-order fee grows with the duty. On Zonos's own pricing-page example, an order carrying $41 in duties, taxes and fees pays a $6.10 fee, and the 10% part, $4.10, is two-thirds of it ^[1].

Two more lines from the same page change the math for a 3PL: an order with no duty or tax pays only the $2, and customers cross-docking with Zonos pay a $5 export processing fee. Where only DDU is available, Zonos returns an estimate that is not guaranteed and still charges the $2 on completed orders, without the 10% ^[1]. Its pricing URL now redirects to a contact-sales page ^[2].

Avalara is the opposite case: nothing to multiply. The only price on the AvaTax Cross-Border page is a navigation link to Avalara Select, "Sales tax and returns plans starting at $69/mo", which is sales tax, not cross-border ^[5].

How much does HTS classification cost per item, from an API or a broker?

Published per-item classification prices on October 10, 2026 ran from £0.10 a call on SimplyDuty's classification API to $125 an item on Tarifflo's pay-per-item plan; licensed customs brokers quote per client, and we found no published broker fee schedule to cite ^{[9] [15]}.

Sources: ^{[3] [4] [9] [13] [14] [15] [16]}.

Easyship's HS Code API, $0.03 to $0.05 a call, is not in this table: its List HS Codes endpoint filters codes by code or description for you to choose from, so it is a lookup, not a classification ^{[7] [8]}.

At a 3PL's volume, the number that decides the classification bill is not 3 million lookups but how many of them are new SKUs. A SKU needs its 10-digit code once, until the product or the HTS changes; its duty has to be priced again for each entry, because the layers that apply depend on when the goods are entered and where they come from. The forced-labor Section 301, for example, applies to goods "entered for consumption, or withdrawn from warehouse for consumption, on or after 12:01 a.m. eastern time on July 24, 2026" ^[22]. GingerControl's API takes no entry date: it returns the U.S. duty layers in force when you call it, so call it close to the entry, and use the Tariff Calculator in GingerLite when you need a specific entry date. Budget classification per new SKU and duty per entry, and ask each vendor which of the two its unit covers.

The hard SKUs set the real cost. GingerControl's own product documentation puts a manual comparison at 30 minutes to 2 hours per product, and 2 or more hours for a compliance-grade report. In the GingerLite app, the Classification Researcher works through the GRI from the 4-digit heading to the 10-digit code, detects composite goods under GRI 3(b) and records which component gives the product its essential character, reads CBP CROSS rulings during the classification, and asks when one missing fact decides the code ("Ginger doesn't guess. It asks."). One classification with its report takes 3 to 5 minutes. The API uses GingerControl's Quick classification line instead, at batch scale.

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 general cost of manual classification against an API is in HTS Code Lookup API vs Manual Classification. Whether to build your own classifier is in Build vs. Buy.

What does a wrong HTS code cost next to the API bill?

A wrong HTS code costs the importer the duty it underpaid, which after a section 1592 violation CBP must require restored "whether or not a monetary penalty is assessed", and it can add a civil penalty under 19 U.S.C. 1592 of up to two times the lost duties, taxes and fees for negligence or four times for gross negligence, capped at the merchandise's domestic value ^[19].

If CBP sends a pre-penalty notice, review Section 1592 pre-penalty defense and mitigation before treating the proposed amount as a final assessment.

Source: 19 U.S.C. 1592(c) and (d), read on govinfo.gov on October 10, 2026 ^[19].

Per dollar, that means each $1 of duty a wrong code underpays must be paid back, and a negligence penalty can add up to $2 more, gross negligence up to $4, within the domestic value cap. A prior disclosure made before CBP opens a formal investigation limits a negligence or gross negligence penalty to interest on the unpaid duty, as long as the duty is tendered ^[19]. The statute also says "Clerical errors or mistakes of fact are not violations of paragraph (1) unless they are part of a pattern of negligent conduct," and that "the mere nonintentional repetition by an electronic system of an initial clerical error does not constitute a pattern of negligent conduct" ^[19]. Whether a wrong code is a clerical error or a mistake of fact is a question for your broker or counsel, so do not budget on that exception.

CBP looks to the importer for that bill, not to the API vendor. Under 19 CFR 141.1, duty is "a personal debt due from the importer to the United States", and under 19 U.S.C. 1484 the importer of record makes entry "using reasonable care" ^[26]. For a 3PL, that importer of record is your client or you, entry by entry. A vendor pays only what its contract promises; Zonos's guarantee covers an HS code changed by the broker or customs, but not an inaccurate code change by the shipper ^[2].

Errors run in both directions. CBP's Trade Compliance Measurement program samples entry summaries to estimate both: for fiscal year 2025 (preliminary), estimated under-collection was $8,051 million and over-collection $5,515 million, with an overall trade compliance rate of 98.6%; for fiscal year 2024 (final), $12,231 million under and $568 million over ^[24]. An overpaid code costs your clients duty, too, and where goods also owe import VAT, a wrong code moves both the duty and the VAT.

As a hypothetical: if 5% of 3 million lookups carried a wrong code, that is 150,000 items, each with its duty wrong in either direction, plus up to two or four times any underpaid part. Only your clients' entry data can put a dollar figure on the average miss. What we can say is when the cheaper API costs more: once its extra wrong codes, times the duty each one misses, times one plus the penalty multiple, are larger than the price gap between the two offers.

That is why accuracy belongs in the pricing comparison, stated with its definition. On GingerControl's own internal test of 1,000+ products, the Quick classifier, the one the API uses, matched 99.86% of codes at the 10-digit level. Avalara states no accuracy percentage for Cross-Border or Tariff Code Classification ^{[5] [6]}. Ours is an internal test, not an independent benchmark, so test any vendor on your own hardest SKUs.

The duty math has its own failure modes. Jet Import Brokers, a U.S. customs broker, told us several well-known tariff tools it tried gave wrong or incomplete rates: conditional exemptions missing, and watches returning error codes ^[20]. A cheap lookup that drops a line is still a wrong number on an entry.

Why doesn't GingerControl publish an API price?

GingerControl does not publish an API price because the Classification + Tariff Calculation API is sold to enterprise customers only, and it starts with a call: each production key's rate limit and item quota are sized to that customer's calling pattern, IP allowlist and peak QPS ^{[16] [17]}.

What it is. GingerControl's API for HTS classification and U.S. duty, POST /openapi/v1/tariff (batches go to /openapi/v1/tariff/batch). Your system sends a product description and its country of origin, one product or a batch of 120 items per call by default, sized to your throughput.

Price. Enterprise customers only, it starts with a call, and there is no published price, no public tester and no test keys. A customer gets a key after the call, sized to its calling pattern. We will not publish a per-call figure, and this post makes no price claim against any vendor.

What it does well.

• A 10-digit U.S. HTS code, the general (MFN) and special rates, and one list per duty layer (Section 301, Section 232 metals, other Chapter 99 lines), each entry a Chapter 99 heading with its rate; an empty list means that layer does not apply
• Split-code goods such as Chapter 91 watches come back as a components array, each part with its own 10-digit code and duties
• Optional steel_pour_country and aluminum_pour_country inputs for Section 232 metals
• Each item keeps your item_id and its own status, ok or failed, in the order you sent it, so one product that fails does not sink the batch
• Item quota is counted per item, not per request: a batch of 120 draws 120 items from the same quota the single endpoint uses, on top of request-level rate limits, and going over returns a 429 with a Retry-After header

Where its use case ends. It covers the duty part of landed cost for U.S. imports: your system applies the rates to the customs value and adds freight, insurance and fees. It takes no entry date or value, so a past or future entry date is priced in the Tariff Calculator instead. It does not do checkout DDP, VAT or GST, sales tax, non-U.S. duty, AD/CVD computation, entry filing or export control classification; there is no export control API. VAT calculation is a separate job from classification. A licensed customs broker reviews each code before it goes on an entry, the broker files, and CBP sets the final duty at liquidation.

Best for. 3PLs, postal operators, logistics providers and platforms that classify U.S. imports at volume and want the code and every duty layer from one call.

Two other ways in, if an API is not the job. For a smaller team classifying a few products a day, the GingerLite app at app.gingercontrol.com is $150 a month for 300 credits, with top-ups if you run out; every classification and every Tariff Calculator run uses credits, and batch classification is not part of GingerLite. For a manufacturer whose whole process needs rechecks, GingerOS watches new rules and changes in its ERP, PLM and supplier records and rechecks every SKU a change touches; it is quoted per project after Prototype Week: one call, a clickable prototype of your own flow in three days, and a quote after. Systems built for company-wide duty estimation are compared in Top Customs Duty Estimation Systems.

Where does each duty and tax API fit best?

Zonos fits merchants who want duties and taxes guaranteed at checkout, Avalara fits companies already on AvaTax, Easyship fits shippers who already have codes, SimplyDuty and Dutify fit small published-plan volumes, and Hurricane Commerce and Descartes fit enterprise buyers who expect a quote; GingerControl's Classification + Tariff Calculation API fits U.S. inbound classification and duty at volume.

Zonos

What it is. A cross-border landed cost platform with guaranteed duties and taxes at checkout and Zonos Classify for AI HS classification. Its docs say "We support calculations for 217 countries and territories", with a GraphQL API and a documented REST POST /v1/landed_cost call ^[2].

Price. $2 plus 10% per guaranteed order, with up to one year of guarantee "for an additional 10% of the duty and tax amount"; Classify from $500 a month; Landed Cost customers "receive 10,000 product classifications annually at no additional cost" ^{[1] [2] [4]}.

What it does well. The guarantee: Zonos says that if customs or carriers charge more than it quoted, it pays the difference. It also handles EU IOSS, UK VAT, Australia GST, New Zealand GST, Singapore GST and Norway VOEC filing, and Classify returns HS codes of 6 to 14 digits ^{[2] [3]}.

Where its use case ends. The per-order meter assumes a checkout and a shopper; for inbound SKUs the meter is a Classify plan, and the volume behind each starting price is not stated. Zonos's eligibility page says the guarantee does not cover inaccurate HS code changes by the shipper or inaccurate customs documentation, and Classify does not handle export codes such as Schedule B ^{[2] [3]}.

Keep HTS codes versus Schedule B export codes separate when the same product record supports both imports and exports.

Best for. Merchants selling DDP to shoppers in many countries. The API side by side with ours is in Zonos API Alternative.

Avalara AvaTax Cross-Border

What it is. In Avalara's words, "Avalara AvaTax Cross-Border calculates and estimates customs duties and import taxes in real time", with Avalara Cross-Border Estimated for new transactions without HS codes and Tariff Code Classification, where the old 3CE site now redirects, for codes "in more than 180 countries" ^{[5] [6]}.

Price. Quote-based; no price on the Cross-Border or Tariff Code Classification pages, which ask for a form or a demo. Avalara's developer site links an "AvaTax 90 days free trial" without saying whether Cross-Border is included ^{[5] [6]}.

What it does well. One vendor for U.S. sales tax and cross-border duty and import tax, "1,400+ signed partner integrations", and a classification team of "260+ classifiers, plus proprietary AI" ^{[5] [6]}.

Where its use case ends. Real-time calculation needs HS codes: the FAQ answers "For real-time calculation of customs duties and import taxes, yes." Estimated mode "only applies to new transactions; any backdated transactions will need an accurate HS-10 code", and no accuracy percentage is published ^[5].

Best for. Companies already running AvaTax for sales tax. The rest of the comparison is in our Avalara Cross-Border API alternative.

Easyship

What it is. A shipping platform that calculates taxes and duties for "220+ destinations", with a free Import Duty Calculator and a Tax and Duties API, POST /2024-09/taxes_and_duties, that returns tax, duty and import_duty_details with the base rate, additional rates such as "anti-dumping duties, section tariffs", and whether the FTA or general rate was applied ^{[7] [8]}.

Price. $0.09 to $0.11 per Tax and Duty call and $0.03 to $0.05 per HS code lookup, inside U.S. plans from $0 to $199 a month; Enterprise is "Contact Us", and "Plan inclusions and pricing may vary by country" ^[7].

What it does well. A published per-call price you can budget against, a sandbox that "allows you to test all of the APIs", and duty detail that separates base and additional rates ^[8].

Where its use case ends. Each call needs an 8- or 10-digit HS code, the endpoint "requires an advanced scope", and its docs say "Non-percentage duty tariffs are not supported" ^[8].

Best for. Shippers already buying labels on Easyship who have codes for their goods. More in our Easyship duty calculator API alternative.

SimplyDuty

What it is. A "Classification, Calculation & Duty Rate API" owned and operated by ParcelWorks Limited of Leatherhead, UK, that takes a product description and returns a 10-digit HS code ^[9].

Price. £0.10 per call pay-per-use, or Basic £9.99 (100 calls a month), Start-up £49.99 (500), Professional £99.99 (1,000) and Enterprise £499.99 (5,000). The pricing page is dated 2019, though these prices were live on October 10, 2026, and whether they include VAT is not stated ^[9].

What it does well. A simple published price, the same for classification and for duty calculation.

Where its use case ends. The largest plan is 5,000 calls a month, and "some API endpoints perform multiple lookups during a single call and will be counted per lookup". Its U.S. tariff update page reads "Last Updated: 29/05/2025", so check how it reflects the forced-labor Section 301 from July 24, 2026 before relying on it ^[9].

Best for. Small, steady volumes with a list price. The side-by-side is in SimplyDuty vs GingerControl.

Hurricane Commerce

What it is. The Kona API, "HS Classification for 10 digits and beyond" plus duty and tax calculations, reachable "via direct API integration" or through the Hurricane Portal without integration ^[12].

Use trade compliance API integration from pilot to production to plan authentication, data mapping, error handling and production monitoring together.

Price. Quote-based ("Book a Demo") ^[12].

Where its use case ends. Hurricane says it has been "consistently proven to be the most accurate time and time again in side-by-side tests", but its page shows no test data, so ask for it ^[12].

Best for. Teams that want classification and duty and tax from one vendor, by API or portal.

Dutify

What it is. A landed cost calculator API, POST /api/v1/landed_cost_calculator, that "can classify items using product titles or partial HS codes", per API docs dated August 29, 2025, more than a year before this check ^[10].

Price. Basic $15 a month (200 calculations, 50 HS lookups), Plus $75 (2,000 calculations, API access) and Pro $149 (5,000 calculations, 1,000 HS lookups); the API is on Plus and Pro only, and the free start is 3 calculations and 3 HS lookups a month ^[10].

Best for. Small stores under 5,000 calculations a month.

Descartes

What it is. AI-assisted HTS classification software on trade content its page puts at "175+ countries"; its CustomsInfo site says "190+ countries" ^[11].

Price. No public price ^[11].

Best for. Enterprises that want deep multi-country tariff content in one contract; GingerControl does not license content databases.

By the numbers

• $2 + 10%: Zonos's fee per guaranteed landed cost order, read October 10, 2026 ^[1].
• 12.5%: the forced-labor Section 301 rate on goods of China and 37 other economies entered from July 24, 2026, a new line every duty lookup on those goods had to pick up ^[22].
• 0.3464%, $34.58 and $670.86: the MPF rate, minimum and maximum for entries from October 1, 2026, which your system adds on top of the duty ^[23].
• $216.7 billion: total duty, taxes and fees CBP collected in fiscal year 2025 ^[21].
• July 1, 2027: the statutory repeal of de minimis takes effect; the exemption has been suspended for all countries since August 29, 2025, so every parcel needs a code and a duty ^[25].

Which duty and tax API fits which job at a 3PL?

GingerControl's Classification + Tariff Calculation API fits the U.S. inbound work of classifying SKUs and pricing every duty layer per item; Zonos and Avalara fit the checkout and tax jobs GingerControl does not do.

How to make the call: if most of your 250,000 monthly lookups are inbound U.S. SKUs that need a 10-digit code and every Chapter 99 line, start with GingerControl's Classification + Tariff Calculation API and compare what you are offered with the per-call plans on cost per item. If merchants collect duties and taxes at checkout, or clients already run AvaTax for sales tax, Zonos or Avalara is the better pick; the three are compared head to head in Zonos vs Avalara vs GingerControl. If you hold codes and fit a published plan, SimplyDuty, Dutify or Easyship gives you a list price without a sales call. If most lookups are repeat SKUs, negotiate the duty unit first; if new SKUs outpace your code checks, the classification unit and its stated accuracy matter more.

Putting a per-item duty price into next year's budget

A budget line for 3 million lookups holds up in front of a CFO when every vendor's price is put on the same unit and set next to what a wrong code costs. GingerControl's Classification + Tariff Calculation API returns a 10-digit HTS code and each U.S. duty layer per item, 120 items per call by default; it is for enterprise customers only, and it starts with a call, after which your key is sized to your calling pattern. Size an API key to your 250,000 lookups a month

For a team that classifies a few products a day without an API, the Tariff Calculator in the GingerLite app prices one HTS code across 200+ origins with each Section 232 and 301 line, MPF and HMF.
