Tariff classification of geomembranes confirmed under Heading 5911 as textile products for technical use, not plastic articles.

Geomembranes manufactured by weaving HDPE strips into fabric and then laminating and processing that fabric were held classifiable under Heading 5911 as textile products for technical uses, not under Heading 3926 as plastic articles. The controlling reason was that the product and manufacturing process were identical to those considered by the jurisdictional High Court in a prior matter, and that binding ruling determined the tariff classification. Earlier contrary departmental rulings were distinguished and could not prevail against the High Court's decision. The advance ruling was therefore affirmed and the departmental challenge failed.

Issues: (i) Whether geomembranes manufactured from HDPE strips and laminated with plastic are classifiable under Heading 5911 as textile products and articles for technical uses, or under Heading 3926 as plastic articles.

Analysis: The product was found to be manufactured by weaving HDPE tapes/strips into fabric and then subjecting the fabric to further lamination and processing, resulting in geomembranes used for technical purposes. The same product and manufacturing process had already been examined by the jurisdictional High Court in an identical matter, where it was held that geomembranes fall under Chapter 59 and not Chapter 39. The earlier contrary rulings relied upon by the Department were distinguished and could not override the binding effect of the jurisdictional High Court's decision on the same product and facts.

Conclusion: Geomembranes are classifiable under Heading 5911 and not under Heading 3926, and the advance ruling was correctly upheld.

Final Conclusion: The departmental appeal failed, and the classification of geomembranes as textile products for technical use was affirmed.

Ratio Decidendi: Where the product and manufacturing process are identical, the jurisdictional High Court's final ruling on tariff classification is binding and geomembranes manufactured by weaving HDPE strips and further laminating them are classifiable as textile products for technical uses under Heading 5911.
