H356778 June 24, 2026 OT:RR:BSTC:CCR H356778 JLE CATEGORY: Carriers Tyler A. Keith Flexport Customs LLC 704 Market Street San Franciso, CA 94102 RE: Instruments of International Traffic; 19 U.S.C. § 1322(a); 19 C.F.R. § 10.41a(a)(1); temperature-controlled pallet shipper. Dear Mr. Keith: This is in response to your December 18, 2025, ruling request on behalf of Doubleday Acquisitions LLC (d/b/a “CSafe”). 1 In your request you inquire whether two sizes of CSafe temperature-controlled pallet shippers called the Silverpod RE qualify as “instruments of international traffic” within the meaning of 19 U.S.C. § 1332(a). Our ruling is set forth below. Facts The following facts are from your ruling request and supplements thereto. The subject Silverpod RE is used to transport pharmaceuticals internationally. The subject pallet shipper is manufactured in [ ] and constructed from plastic, polyurethane, and coatings for insulation, heat dissipation, waterproofing, fire resistance and abrasion resistance. Phase change material is used to maintain temperature. The subject Silverpod RE comes in two sizes. 1 You have asked this office for confidential treatment of specific information relating to the identity of your client and their customers, project site locations, number of components utilized, and vessel charters. If this office receives a Freedom of Information Act request for your submission, CBP Regulations (See 19 C.F.R. § 177.2, et seq.) regarding the disclosure of business information provide that the submitter of business information will be advised of receipt of a request for such information whenever the business submitter has in good faith designated the information as commercially or financially sensitive information. We accept your request for confidential treatment as a good faith request. Additionally, there are [ ] subject items in circulation, each has a tracker, a lifespan of [ ] uses, and is re-leased to a new customer upon return after [ ]. Issue Whether the subject Silverpod RE qualifies for consideration as instrument of international traffic within the meaning of 19 U.S.C. § 1322(a) and 19 C.F.R. § 10.41a(a)(1). Law and Analysis Per 19 C.F.R. § 141.4(a), “all merchandise imported into the United States is required to be entered, unless specifically excepted.” The four exceptions to the requirement of entry are listed under 19 C.F.R. § 141.4(b), one of which is instruments of international traffic (“IIT”). 19 C.F.R. § 141.4(b)(3). Subheading 9803.00.50, HTSUS provides for the duty-free treatment of: Substantial containers and holders, if products of the United States (including shooks and staves of United States production when returned as boxes or barrels containing merchandise), or if of foreign production and previously imported and duty (if any) thereon paid, or if of a class specified by the Secretary of the Treasury2 as instruments of international traffic, repair components for containers of foreign production which are instruments of international traffic, and accessories and equipment for such containers, whether the accessories and equipment are imported with a container to be reexported separately or with another container, or imported separately to be reexported with a container. (Footnote and emphasis added). Subchapter 98 of the HTSUS only applies to: (a) Substantial containers or holders which are subject to tariff treatment as imported articles and are: 2 Customs revenue functions have been delegated to the Secretary of Homeland Security by the Secretary of Treasury, with exceptions herein not applicable, under the authority of the Homeland Security Act of 2002, Pub. L. 107-296. See Treas. Dep't Order 100-16 (May 15, 2003). (i) Imported empty and not within the purview of a provision which specifically exempts them from duty; or (ii) Imported containing or holding articles, and which are not of a kind normally sold therewith or are entered separately therefrom; and (b) Certain repair components, accessories and equipment. See U.S. Note 1, et seq., Chapter 98, HTSUS. Pursuant to 19 U.S.C. § 1322(a), IITs shall be excepted from the application of the Customs laws to the extent that such terms and conditions are prescribed in regulations or instructions. The relevant CBP regulations implementing that statute is found at 19 C.F.R. § 10.41a(a)(1) which provides in pertinent part: Lift vans, cargo vans, shipping tanks, skids, pallets, caul boards, and cores for textile fabrics, arriving (whether loaded or empty) in use or to be used in the shipment of merchandise in international traffic are hereby designated as “instruments of international traffic” [. . .] The Commissioner of Customs [now CBP] is authorized to designate as instruments of international traffic […] such additional articles or classes of articles as he shall find should be so designated. 19 C.F.R. § 10.41a(a)(1) (emphasis added). Such instruments may be released without entry or payment of duty, subject to the provisions of this section. To qualify for entry-free and duty-free treatment as IITs under the aforementioned statutory and regulatory authority, the article must be a substantial container or holder. As stated above, CBP is authorized to designate as an IIT such additional articles not specifically noted in 19 C.F.R. § 10.41a(a)(1). To qualify as an IIT within the meaning of 19 U.S.C. § 1322(a) and 19 C.F.R. § 10.41a(a)(1), an article used as a container or holder must be: (1) substantial, (2) suitable for and capable of repeated use, and (3) used in significant numbers in international traffic. See HQ H291037 (Jan. 9, 2018); HQ H016491 (Oct. 1, 2007); HQ 114150 (Dec. 12, 1997); HQ 107545 (May 7, 1985); Treas. Dec. 71-159, Cust. B. & Dec. 296 (June 18, 1971); 99 Treas. Dec. 533, No. 56247 (Aug. 26, 1964).3 CBP has reviewed similar items. In HQ H348215, CBP determined certain temperature-controlled pharmaceutical containers made from aluminum which used phase change materials to maintain temperature qualified as IITs. See HQ H348215 (Aug. 20, 2025). In HQ H339291, CBP determined certain temperature-reuseable pallets made from plastic qualified as IITs. See HQ H339291 (Jul. 1, 2024). In HQ H409432, CBP ruled that certain temperature-controlled 3 The requirement that an article be “substantial” is not only a threshold requirement under 9803.00.50, but also a requirement for an article to be an instrument of international traffic pursuant to CBP decisions. The origin for the criterion found in CBP decisions that an article be “substantial” is found in Schedule 8, Item 808.00 of the Tariff Schedule of the United States (1963) (TSUS), the predecessor provision to 9803.00.50, HTSUS. Likewise, the criterion that an article be “suitable for and capable of repeated use” is found in Schedule 8, Item 808.00, TSUS, Headnote 6(b)(ii)(stating that the article must be capable of “reuse”). Although the requirement that an article be capable of reuse is no longer under subheading 9803.00.50, HTSUS (the successor provision to Item 808.00, TSUS), to receive duty-free treatment thereunder nevertheless, “reuse” is still required, pursuant to CBP decisions, for an article to be considered an instrument of international traffic. containers that were reusable with a hundred containers used in international traffic per year qualified as IITs. See HQ H409432 (Apr. 28, 2022). In the present matter, the subject Silverpod RE is substantial in that it is constructed from plastic, polyurethane and coatings for insulation, heat dissipation, waterproofing, fire resistance and abrasion resistance. The subject item is suitable for and capable of repeated use as it can be used multiple times per year over the course of several years. Finally, the subject Silverpod RE is used in significant numbers as hundreds are in circulation. In accordance with the information above, the subject item qualifies for treatment as an instrument of international traffic under 19 C.F.R. 10.41a(a)(1) and is eligible for duty-free admission. Holding The subject Silverpod RE qualifies for treatment as an IIT within the meaning of 19 U.S.C. § 1322(a) and 19 C.F.R. § 10.41a(a)(1). Please note that 19 C.F.R. § 177.9(b)(1) provides that “[e]ach ruling letter is issued on the assumption that all of the information furnished in connection with the ruling request and incorporated in the ruling letter, either directly, by reference, or by implication, is accurate and complete in every material respect. The application of a ruling letter by a {CBP} field office to the transaction to which it is purported to relate is subject to the verification of the facts incorporated in the ruling letter, a comparison of the transaction described therein to the actual transaction, and the satisfaction of any conditions on which the ruling was based.” If the articles vary from the facts stipulated to herein, or CBP ascertains discrepancies based upon a review of any other pertinent information, this decision shall not be binding on CBP as provided for in 19 C.F.R. §§ 177.2(b), 177.9(b).
