拆分码组合计税

第 91 章产品（如手表）需按组成部件分别计税，而非以整体计算。我们的 API 会自动将这类产品拆解为各个组成部件，每个部件都有独立的 HTS 编码和关税计算。在请求中使用 components 字段即可获取每个组件的税率明细。这是大多数分类 API 直接跳过的功能，但真正的贸易合规意味着每一个产品都必须获得正确的关税待遇，没有例外。

Overview

The GingerControl OpenAPI provides a REST interface for automated HTS classification and tariff calculation. With a single API call, you can send a product description and country of origin and receive the corresponding HTS code along with a full tariff breakdown, including General (MFN) rate, Special rate, Section 301, Section 232 Metals, Section 122, and all applicable Chapter 99 entries.

Single-Product Endpoint

Classify one product per request with full tariff details

Batch Endpoint

Process up to 120 products in a single request

Split-Code Support

Handles split-code products with component-level tariffs

Full Tariff Stack

MFN + Section 301 + 232 + 122 + Chapter 99

Integration Steps

Step 01

Read the API Contract

Before you start integrating with the GingerControl OpenAPI, we recommend that you read the API contract below in full. This will help you quickly understand the request patterns, input and output structures, error semantics, and rate-limiting rules, which in turn reduces integration and debugging effort.

Step 02

Request a Test API Key

Once you understand the API contract, please contact us offline to request a test API key. After we receive your request, we will issue a test key and deliver it to you through an offline channel, such as email.

Warning

Test API keys come with a relatively small traffic quota and are typically valid for only 7-30 days. They are intended for development and debugging only and must not be used in production.

Step 03

Development and Debugging

After you receive your test API key, you can begin development and debugging. In most cases, you will complete the basic API integration quickly, and then spend more time integrating the returned data into your own system.

Step 04

Production Integration

Once your system integration is complete and you are ready to go live, please contact us offline to request a production API key. To ensure service quality, we may need to learn more about your calling patterns, IP allowlist, peak QPS, latency expectations, and related information before issuing a production-grade API key and delivering it to you through an offline channel.

Warning

Please keep your production API key secure. At the current stage, the API key is the sole basis for billing.

Rate Limits & Quotas

All API calls are subject to request-level protection. When request frequency is too high, the system returns 429 Too Many Requests.
Quota is consumed by the number of products processed. The single-product endpoint consumes 1 item, while batch consumes based on the number of items.
Both endpoints share the same item-level quota under the same API key.
Test API keys have relatively small traffic quotas and are intended only for development and integration testing.
Production API keys are configured based on each customer's traffic model.

Development Recommendations

Validate request bodies

If you receive 422, the request body structure, field types, or field values usually do not match the contract. Check the request body first.

Handle rate limits gracefully

If you receive 429, implement retry behavior using the Retry-After response header.

Log request IDs

Keep request logs and record the X-Request-Id for each call. This significantly reduces troubleshooting time.

Configure timeouts and retries

Configure reasonable timeouts, retries, and failure alerts so that network fluctuations can be handled robustly.

Security Recommendations

Do not embed your API key in frontend code, browser code, or any environment exposed to end users.

Do not use production API keys in test, development, or temporary debugging environments.

Store your API key in a secure configuration system, such as a secret manager or tightly controlled environment variables.

If an API key is lost, suspected to be leaked, or needs to be rotated, please contact us as soon as possible.
