Determining Polyethylene Specific Gravity Thresholds for Tariff Entry
Polyethylene tariff entry requires density testing per ISO 1183-1 Method A on annealed plaques, where crossing 0.940 g/cm³ shifts classification from 3901.10 to 3901.20.
HTS 3901.10
Meaning
Tariff classification schedules organize imported polymer resins to determine customs duties and trade statistics. The code hts 3901.10 applies to polyethylene having a specific gravity of less than 0.94 grams per cubic centimeter. This code is used by customs agencies worldwide to identify low density polyethylene imports.
Resin Classification
Density measurements determine the appropriate classification of polyethylene under this code. To classify a resin under hts 3901.10, the specific gravity must be measured using standard test methods such as pycnometry or gradient column. If the density is 0.94 or higher, the resin must be classified under a different code.
This distinction is necessary for customs compliance.
Duty Rate
Customs duties are calculated based on the assigned harmonized code of the imported resin. Resins classified under hts 3901.10 are subject to specific duty rates that vary by country of origin. Some countries have trade agreements that lower the duty rate to zero.
Other countries impose higher tariffs to protect domestic polymer producers from foreign competition.
Trade Impact
Import volumes are tracked using these harmonized codes to monitor trade flows and identify market trends. The use of hts 3901.10 allows trade agencies to monitor the volume of low density polyethylene entering the country. This data is used to investigate trade disputes or to assess the impact of trade remedies on the domestic market.
Importers use this information to make informed decisions about sourcing raw materials and planning production schedules. High tariff rates on these resins can force moulders to find alternative suppliers.
