How Palisade keeps the catalogue correct.

Collection

Every preferential tariff rate in Palisade has three attached sources: the legal agreement text, the implementing gazette notification from the destination country, and the current ITC MacMap record. Where these disagree, we flag the discrepancy and default to the most recent primary source.

For India specifically, we track both the Central Board of Indirect Taxes and Customs (CBIC) notifications and the Agriculture Infrastructure Development Cess (AIDC) surcharges separately, since India's effective import duty on agricultural commodities includes multiple layered duties that change on different notification cycles.

Versioning

Every tariff rate is versioned. When a rate changes, we keep the old record with its effective dates, so any shipment from the past 12 months can be audited against the rate that was legally in force on the day it cleared customs, not the rate that is in force today.

We ship a changelog. Every rate change in the catalogue over the past 90 days is visible to pilot customers.

Origin rules

Rules of origin are checked against the agreement text's Product-Specific Rules (PSR) annex. For each HS code on a given corridor, we store:

• Regional Value Content (RVC) threshold
• Change in Tariff Heading (CTH) requirements
• Specific process requirements (where applicable)
• Cumulation provisions across ASEAN members

Rules are applied against the user's bill of materials. Where we don't have a BOM, we flag the rule as unchecked rather than guessing.

What is automated, what is analyst-reviewed

We publish the ratio of automated to reviewed decisions in every monthly pilot report.

What 'verified' means

A rate is marked verified in Palisade when all four are true:

1. 01
   The preferential rate is confirmed against the agreement's Schedule of Concessions for the specific HS code and destination country.
2. 02
   The effective MFN rate is confirmed against the latest gazette notification or customs tariff (including all surcharges and cesses).
3. 03
   The origin rules have been confirmed for the specific lane.
4. 04
   The 'applicable lower rate' logic has been applied (important for India AIFTA Special Products).

What we do not guarantee

• Palisade is an intelligence product, not a legal opinion. Use with your customs broker or trade counsel.
• Rates can change between the last catalogue refresh and your shipment clearance. We surface the date each rate was last verified.
• Non-tariff measures (NTMs), anti-dumping duties, and countervailing duties are flagged but not priced.
• TRQ (tariff-rate quota) utilisation is surfaced but not predicted.

What we fix if we get it wrong

If a Palisade recommendation leads to an underpaid or overpaid duty claim, we will work with the pilot customer and their broker to file the post-clearance amendment. We do not charge for error correction during the pilot year.

On the ASEAN Tariff Finder

The ASEAN Tariff Finder (launched August 2023, operated by the ASEAN Secretariat) is a useful public reference, and we use it ourselves as a cross-check against ITC MacMap. It covers preferential rates for ATIGA, ACFTA, AJCEP, AKFTA, AIFTA, AANZFTA, AHKFTA, and RCEP across the ten original ASEAN members.

Palisade is a different layer. The ATF tells you what the rates are. Palisade takes your shipments, reconciles each one against every applicable preferential regime on that corridor, checks origin eligibility against the underlying rule-of-origin text, and generates a post-clearance refund packet where a gap exists. Palisade tells you whether you claimed the right one.
