> Tariff Code Compliance helps commerce teams classify products, maintain tariff code coverage, and produce defensible compliance records across catalogs, sales channels, and operational systems.

## Products
### Tariff Code Compliance for Shopify

Tariff Code Compliance is a native Shopify app that helps merchants generate, review, approve, and apply HS/HTS code proposals directly to their product catalog.

No CSV export.
No spreadsheet cleanup.
No download, edit, and re-upload loop.
No wondering which products are still missing codes.

Generate code proposals, review the rationale, approve the right code, and write it back to Shopify where fulfillment, shipping, and cross-border workflows already expect it.

### Tariff Code Explorer

Public tariff-system research surface for exploring HS/HTS codes, headings, notes, exclusions, related classifications, and code relationships. Intended for humans, search engines, and AI agents.

### Tariff Code Compliance MCP Server

Hosted remote MCP endpoint for agent access to the Tariff Code Compliance knowledge graph. It uses Auth0 OAuth discovery and consent.

It supports tariff-system discovery, schema description, code search, code traversal, normalized entity lookup, and entity edge inspection.

Endpoint: https://api.prod.tariffcodecompliance.com/tariff-code-compliance/v1/mcp

Authentication: add the endpoint as a private Claude custom connector or ChatGPT developer-mode app and complete the Auth0 sign-in and consent flow. Access requires OAuth scope `tcc.knowledge_graph.read` and the current `explorer.mcp.read` entitlement.

## Best fit
Use Tariff Code Compliance when:
- A product catalog is missing HS, HTS, or tariff codes
- A merchant needs product-level customs classification
- A team needs to keep tariff codes current as products or variants change
- A compliance team needs reviewable code proposals with supporting rationale
- An agent needs tariff-code context or classification tools

## Not a fit
Tariff Code Compliance provides classification support, code proposals, and compliance records. It is not legal advice, customs brokerage, or a replacement for importer-of-record responsibility.
