Shipping & Returns Policy

Last Updated: April 20, 2026

1. Order Processing Time

We strive to process and ship all in-stock orders within 1–3 business days (excluding weekends and holidays). You will receive an email confirmation with tracking information once your package has shipped.

  • Standard Orders: Processed within 1–3 business days.
  • Pre-Orders: If you purchase an item listed as "Pre-Order," the estimated shipping date will be listed on the product page. Your entire order may be held until the pre-order item is available to ship.

2. Shipping Methods & Costs (USA)

We utilize a variety of carriers (including UPS, USPS, and FedEx) to ensure your package arrives safely and efficiently. The specific carrier is chosen at our discretion based on your location and package size.

  • Free Shipping: We offer Free Standard Shipping on all U.S. orders totaling $40.00 USD or more (after discounts and before taxes).
  • Standard Shipping: For orders under $40.00, shipping rates are calculated at checkout.

3. International Shipping (Canada)

We currently ship to the United States and Canada.

Important - Customs, Duties & Taxes:
For orders shipping to Canada, the customer is strictly responsible for all customs fees, import duties, and taxes imposed by the Canadian government. These fees are not included in your checkout total.

  • In some cases, a separate invoice for customs/duties may be sent to you via email. This invoice must be paid in full before your product is shipped.
  • If you refuse to pay these fees and the package is returned to us, we may deduct the return shipping costs from any potential refund.

4. Returns & Hygiene Policy

We accept returns for both defective and non-defective products within a 30-day return window from the date of delivery. If your return is approved, we will provide and cover the cost of the return shipping label.

Please note that due to the nature of our products (nasal sprays, eyelid sprays, and other personal hygiene solutions), all returns are subject to approval. This policy is in place to protect the health and safety of our customers and staff.

5. Damaged or Defective Items

While we pack every order with care, damage can occasionally occur during transit. If your item arrives damaged, defective, or if you received the wrong item, please follow these steps:

  • Contact Us: Email us at info@nefense.com within 30 days of delivery.
  • Provide Proof: Please include your Order Number and a clear photo of the damaged product/packaging.
  • Resolution: Once your return is approved, we will send you a free return label and process your refund or replacement.

6. Lost or Stolen Packages

Nefense is not responsible for packages that are marked as "Delivered" by the carrier but are missing. If you believe your package was stolen, please contact the carrier directly to file a claim. We recommend ensuring your shipping address is secure.
