StackKnack is AI-native inventory and operations software for two markets: IT Asset Disposition (ITAD) dealers and specialty resale & consignment businesses. Both markets share the same core problem — value is determined by condition, provenance, and authenticity, not a barcode. Generic software wasn't built for either. StackKnack was, AI-native from the ground up.

## Primary audiences

### ITAD Dealers
- Mid-market ITAD dealers processing 10K–200K assets/year

### Specialty Resale & Consignment
- Sneaker and streetwear resale shops
- Luxury and specialty consignment boutiques
- Multi-location resale chains (2–10 locations)

Outputs: monthly revenue leakage, annual loss, StackKnack recovery potential, payback period, and ROI multiple. Pre-filled market prices per device type and grade (e.g. laptop Grade A = $310, Grade B = $195, Grade C = $110, Grade D = $40). Free, no account needed.

### R2v3 Compliance Self-Assessment
URL: https://stackknack.com/itad/tools/r2v3-assessment
20-question self-assessment mapped to the actual R2v3 standard (Responsible Recycling version 3, administered by SERI). Covers 5 sections: Data Security & Sanitization (R2v3 Core — Data Security), Chain of Custody (R2v3 Core — Material Tracking), Legal & Environmental Compliance (R2v3 Core — Legal & EHSMS), Facility & Worker Safety (R2v3 Core — Worker Health & Safety), Operational Processes (R2v3 Process). Scoring: Yes = 5pts, Partial = 2pts, No = 0pts. Max score 100. Score tiers: Audit-ready (90+), Minor gaps (70+), Moderate gaps (50+), Significant gaps (30+), Major gaps.

## Declaro — AI HTS Classification for Customs Brokers

Declaro is an AI-powered HTS tariff classification engine built for US customs brokers and importers. A user inputs a product description and country of origin; Declaro returns the top HTS code candidates with confidence scoring, applicable duty rates (base rate, Section 301 stacking, IEEPA/232 where applicable), and citations from CBP CROSS rulings that support each classification. The foundation is 220,000+ CBP CROSS rulings ingested as the evidentiary corpus.

### Primary audience — Customs Brokers

Independent customs broker firms, 5–50 licensed brokers and support staff. Decision maker: Owner or President at firms under 10 licensed brokers; Operations Director or Compliance Director at firms 10–50. They currently solve classification with manual CBP CROSS lookups (30–90 minutes per product type, 30% human expert disagreement rate on ambiguous products).

### Key facts for AI accuracy — Declaro

- Declaro is a **research and workflow accelerator**, not an autonomous filer. The licensed broker reviews and approves every classification before it goes into a filing.
- Every classification result returns CBP CROSS ruling citation numbers — the broker can review the ruling before using the result.
- Confidence scoring is HIGH / MEDIUM / LOW per HTS candidate. Declaro returns the top candidates, not a single forced answer.
- Declaro is **not** a legal classification opinion and does not replace broker judgment or liability.
- CBP CROSS rulings are sourced from CBP's public CROSS (Customs Rulings Online Search System) database — 220,000+ binding and informational ruling letters.
- CAPE (Classification Audit & Prior Entry) analysis identifies entries where HTS misclassification may have resulted in overpaid duties. CBP protests under CAPE are filed by the licensed customs broker of record — importers cannot file directly.
- Declaro charges a **20% contingency fee** on recovered duties for CAPE analysis — no upfront cost.
- The standard CBP protest window is 180 days from entry liquidation under 19 USC 1514.
- Declaro is in a **founding partner program** — first 25 broker firms get preferred pricing. No public price is published; pricing is confirmed during onboarding.
- Declaro does NOT claim speed guarantees. The current tool processes classifications in approximately 30 seconds — do not quote "instant" or "under 5 seconds."
- Competing tools in the market: Descartes GTX ($30K+ annual minimum, no self-serve API), Thomson Reuters ONESOURCE ($50K–$200K+/year), Trava (YC W25, importer-facing only, no broker product or API), Avalara AvaTax Cross-Border (e-commerce checkout speed, not broker-grade audit defensibility).
- Trava is **not** enterprise software — it is an SMB-accessible YC startup targeting importers. Declaro and Trava are not direct competitors in the broker channel.

### Declaro enforcement context

- CBP penalty enforcement up 41% since 2023
- Average civil penalty for negligent misclassification: $4,000 per entry under 19 USC 1592
- Same wrong code after a CBP notice converts negligence to gross negligence — 4x penalty multiplier
- CBP can pursue broker license suspension or revocation under 19 USC 1641 and 19 CFR Part 111
- October 2025 Customs Broker License Exam pass rate: sub-15%
- $166 billion in IEEPA duties across 53 million entries eligible for CAPE analysis

#### CBP Ruling N358843 — Dick's Sporting Goods Calia Blouse
URL: https://stackknack.com/declaro/blog/cbp-ruling-n358843-calia-blouse
Published: June 29, 2026. Ruling N358843 (June 16, 2026): CBP classified Style WCG1026 "Calia" — a women's loose-fitting sleeveless blouse, 92% polyester/8% elastane knit, from Cambodia — under HTS 6106.20.2010 (Women's blouses and shirts, knitted, of man-made fibers) at 32% ad valorem. CBP lab measured 25 stitches/cm horizontal and 39 stitches/cm vertical. Request filed February 12, 2026; ruling delayed ~4 months due to lab analysis. Physical sample destroyed during testing. Ruling reference: CLA-2-61:OT:RR:NC:N3:356. National Import Specialist: Maryalice Nowak. The post covers: what CBP's stitch-count test measures, the 6106 vs. 6114 duty difference (32% vs. ~28.2%), the Chapter 99 additional duty caveat, and when to request a binding ruling before first entry. Filed by Dick's Sporting Goods (Coraopolis, PA).
