Polypropylene Copolymer versus Homopolymer Impact Resistance
Impact copolymers deliver superior notched and subzero impact resistance over homopolymers by incorporating a dispersed ethylene-propylene rubber phase.
Custom Tariffs
Meaning
Mandatory financial charges applied to imported resin and equipment shipments define the landing cost of raw materials in international trade. Managing custom tariffs involves classifying the specific polymer grade according to the harmonized system code to determine the applicable tax rate. These levies apply at the point of entry and vary based on the country of origin and trade agreements in force.
The application of these fees ceases once the goods are cleared through the border and all duties are settled.
Import Costing
Calculation of the total material expense must account for the basic price and any additional duties. Since custom tariffs can add considerable percentage costs to a shipment, sourcing decisions often shift between domestic and international suppliers. Large volume purchases of virgin resin are particularly sensitive to these fluctuations.
Fluctuating trade policies make the procurement of specialized engineering plastics a volatile segment of the budget.
Sourcing Strategy
Geographic location of a supplier dictates the potential for duty exemptions or preferential rates. While a cheaper unit price abroad may look attractive, the addition of custom tariffs can negate the initial savings. Strategic buyers look for regions with active trade treaties to minimize these costs.
Diversifying the supply base helps mitigate the risk of sudden policy shifts.
Documentation Compliance
Accuracy in the paperwork for each shipment ensures that the chemical composition and intended use of the plastic are correctly identified. Failure to declare the correct code under custom tariffs leads to delays or fines. Proper record keeping allows the importer to prove the validity of their claims during an audit.
