pretty-print-hscode

Pretty print Harmonized System (HS) codes.

HS codes are best stored without dots or labels for processing, but that form is harder to scan. This library adds the conventional separators and optional labels.

Install

npm install pretty-print-hscode

Usage

const prettyPrintHsCode = require("pretty-print-hscode");

prettyPrintHsCode("010203");
// "0102.03"

prettyPrintHsCode("01020304", true);
// "Subheading 0102.03.04"

prettyPrintHsCode("01020304", { showLabel: true, isItem: true });
// "Item 0102.03.04"

prettyPrintHsCode("0102.03");
// "0102.03"

prettyPrintHsCode("I", { showLabel: true });
// "Section I"

The package includes TypeScript declarations and supports the original boolean API: prettyPrintHsCode(code, showLabel, isItem).

API

prettyPrintHsCode(code, options)

prettyPrintHsCode(code: string, showLabel?: boolean, isItem?: boolean): string;
prettyPrintHsCode(code: string, options?: { showLabel?: boolean; isItem?: boolean }): string;

Non-digit separators in numeric HS codes are ignored before formatting. Non-numeric section codes such as "I" are returned unchanged, with an optional Section label. Invalid argument types throw TypeError.
