Shipping, Returns & Warranty Policy

Last updated: October 13, 2026.

This policy applies to purchases of the Med-buying OZ-150 rigid hyperbaric oxygen chamber and related accessories, ordered directly from Changsha Hongbo Medical Technology Co., Ltd. By placing an order you agree to these terms. For distributor / OEM contracts, the signed proforma invoice and framework agreement take precedence.

1. Order process & lead time

  • Deposit: 30% T/T against proforma invoice. Balance 70% before shipment.
  • Production lead time: 20–25 working days from deposit receipt for a standard unit. OEM branding, custom-language firmware, or spare-parts bundles add 5–7 working days.
  • QC before shipment: we send you photos and a short video of your serial number (pressure hold test, touchscreen boot, cabin exterior). Balance payment is only due after you approve the QC video.

2. Shipping terms (Incoterms 2020)

Default term is FOB Shenzhen / Changsha (CIF/DDP available on request). We ship by sea. LCL (less-than-container load) is standard for 1–2 units; FCL 20GP or 40GP is recommended for 3+ units and is cheaper per unit.

  • Estimated sea transit: 25–40 days to Manzanillo, Callao, Santos, Cartagena, Jebel Ali or your designated main port. Times are estimates, not guarantees; port congestion and customs clearance are outside our control.
  • Air freight: not practical for a rigid chamber (over-size, overweight) and is not offered.
  • Documents supplied before the vessel sails: commercial invoice, packing list, bill of lading, CE declaration of conformity, ISO 13485 certificate, QC test report with serial number, and — where your regulator requires — free-sale certificate.
  • Customs & duties: import clearance, duties, taxes (VAT/IVA/IGV) and sanitary registration in the destination country are the buyer's responsibility. We supply whatever documentation your importer needs.

3. Damaged in transit

Every cabin is pressure-tested to 1.5× rated pressure for 30 minutes before packing, then crated in a fumigated wooden export case with foam lining. If you receive visible shipping damage:

  • Do not sign for a clean receipt. Note the damage on the carrier's delivery document, take photos of the crate and the damage, and keep all packaging.
  • Email us within 48 hours with photos and the carrier's damage note.
  • We handle the cargo-insurance claim and ship replacement parts (cabin panel, window, control board, touchscreen) at our cost.

4. Cancellation before shipment

You may cancel a confirmed order within 3 working days of paying the deposit for a full refund. After that window, each unit is built to order, so the deposit covers raw materials and labour already committed and is non-refundable. If your project is delayed rather than cancelled, we will credit the deposit against a future order for up to 12 months.

5. Returns after shipment

Rigid hyperbaric chambers are built to order and classified as Class II medical equipment. Once shipped, returns are not accepted except in the following cases:

  • Dead-on-arrival (DOA): the unit cannot power on or hold pressure after installation, confirmed by a joint video inspection with our engineer. We will repair, replace or refund — your choice.
  • Material manufacturing defect found within the warranty period and confirmed as such after inspection.

Change of mind, wrong market, or importer failing to obtain sanitary registration are not return reasons. We will, however, help you resell or redirect the unit to another clinic at no commission.

6. Refund processing time

Approved refunds are issued by T/T within 14 working days of the return goods being received and inspected. We do not cover return shipping cost unless the return is due to our defect or shipping damage.

7. Warranty

  • Coverage: 24 months from bill of lading date, covering manufacturing defects in the nickel-steel cabin, control board, 7-inch touchscreen, air compressor and built-in air conditioning.
  • Exclusions: misuse, unauthorized modification, failure to follow the user manual, normal wear of consumables (air filters, seals, O-rings, oxygen sensors), and damage from power surges or natural disasters.
  • What we do: ship spare parts free of charge under warranty (buyer covers international courier); for major defects we provide a replacement board or cabin module. All warranty support is delivered by video call in English or Spanish.
  • After warranty: lifetime spare-parts availability at factory cost, and paid remote support.
