Classify any product to a 10-digit HTS code with 98% accuracy in under 100 milliseconds. Built on 10.5 million product digital twins and a dual-model architecture — Claude Opus for accuracy-critical classifications, Gemini Flash for high-volume throughput. REST API at api.goldmexintl.com, ready to integrate into your TMS, ERP, or customs platform.
POST to api.goldmexintl.com/v1/classify with your API key in the Authorization header. Keys are provisioned instantly from the developer dashboard. Free tier includes 100 classifications per month. Enterprise keys support up to 50,000 per day with dedicated rate limits and priority routing to Claude Opus.
Every response includes: hts_code (10-digit), duty_rate (ad valorem %), spi (trade program indicators), pga_flags (agency requirements), confidence (0-1 score), and reasoning (GRI chain). Confidence below 0.85 triggers a review flag.
POST a product description, commercial invoice, image, or barcode to the /classify endpoint. The API accepts plain text, structured JSON, PDF documents, and JPEG/PNG images. Multimodal input means you can send a photo of a product label and get back a classification — no manual data entry required.
Your product is compared against 10.5 million digital twins using NVIDIA 768-dimensional embeddings (HNSW index). The nearest archetype provides a classification anchor. 176,000 Oracle KB entries and 22,800 CBP specification chunks supply the regulatory context for edge cases.
Accuracy-critical classifications route to Claude Opus 4.6, which reasons through GRI (General Rules of Interpretation) step by step. High-volume bulk classifications route to Gemini Flash for throughput — thousands of SKUs per minute at a fraction of the cost. The router selects the model automatically based on product complexity and your plan tier.
The API returns a 10-digit HTS code, duty rate, applicable trade program indicators (SPI), Section 301/IEEPA surcharge flags, PGA agency triggers, and a confidence score. Every response includes the GRI reasoning chain so you can audit exactly why a code was chosen.
Classification responses return in under 100 milliseconds for cached SKUs. First-time classifications complete in 1-3 seconds with full GRI reasoning. Repeat products hit the twin cache and return instantly.
Measured against CBP rulings and licensed broker review. The engine applies all six General Rules of Interpretation in sequence, handling Section Notes, Chapter Notes, and Explanatory Notes that trip up keyword-based classifiers.
Most classification tools stop at 6 digits. We go to the full 10-digit statistical suffix required for US entry filing. The difference matters — duty rates, quota categories, and trade program eligibility all depend on the last four digits.
Every classification response includes appropriate disclaimers per CBP Ruling H350722. The API provides classification assistance — a licensed customs broker reviews and signs off on codes used for actual entry filing.
Send up to 500 products in a single batch request. Each item is classified independently with full reasoning. Batch results stream back as they complete — no waiting for the slowest item to finish before receiving any results.
Once classified, a SKU is cached permanently. When tariff schedules change (IEEPA updates, Section 301 modifications), the cache is invalidated and products are reclassified against the new schedule automatically. You always get the current rate.
Get your API key from the developer dashboard and send your first classification request. Free tier includes 100 calls per month — no credit card required.
