The Harmonized Tariff Schedule assigns a specific duty rate to every category of imported good. How a product is classified determines which rate applies.
Tariff engineering, meaning designing or describing a product to legitimately qualify for a more favorable classification, is a long-recognized legal practice. It is distinct from misclassification or fraud, provided the product genuinely meets the classification criteria claimed.
Plastic packaging components generally fall within HTS Chapter 39, covering plastics and articles thereof. The specific heading depends on function and form.
A PP cap classified as a container closure can carry a different rate than the same resin formed into a different article. Material composition, primary function, and sometimes whether a component is imported assembled or unassembled all shift which subheading applies.
Duty rate is a function of classification and country of origin together. Substantial transformation determines the second variable, which is why moving a program between Jadewell's China and Vietnam plants changes landed cost independent of how the part is classified.
Antidumping and countervailing duties run on a third track entirely, applied per product-country combination on top of the base rate.
Two suppliers quoting the same physical part can legitimately classify it under different HTS codes if the part's documented function or composition differs even slightly. That classification difference flows directly into landed cost.
Request the HTS code a supplier is using for customs entry and verify it against the product as built. Discrepancies are worth resolving before goods ship. Which party carries that exposure depends on the Incoterms, and duty rarely appears on the FOB quote itself.
Legitimate tariff engineering changes the actual product, meaning design, function, or composition, to fit a real classification. Misclassification claims a code that does not accurately describe the product as built.
The distinction matters because misclassification carries real compliance risk, including penalties and retroactive duty assessment, where legitimate engineering is informed design and documentation.
