HAMPHI is the Swedish Tesla-accessory retailer at hamphi.com, and code FREDRIK takes 15% off the entire site. At 15%, FREDRIK matches the highest Tesla-accessory codes we've verified — three times Jowua's 5% and above the 10% Havnby and NovaPads run. The difference from other 15% codes (like TESMAG's AWD) is shipping: HAMPHI operates a real warehouse and storefront in Borås, Sweden, with a workshop in Gothenburg, so EU orders arrive in days rather than the 10–20 days a China-based dropshipper takes.
How to use the FREDRIK code at HAMPHI
- Open hamphi.com
- Pick your vehicle — Model Y (including Juniper), Model 3, Model S, Model X — and add accessories to cart
- At checkout, enter FREDRIK in the discount code field
- Confirm the 15% reduces your subtotal before paying
The code applies to the cart subtotal. It works site-wide across Tesla and EV accessories at hamphi.com.
What FREDRIK saves you across HAMPHI's catalog
HAMPHI curates the higher end of the Tesla-aftermarket category: custom rubber mats, roof racks and rails, cargo grids, mudguards and wheel arch clips, S3XY-style steering buttons, charge-port accessories, and a growing camping line (storage solutions, organizers, road-trip kit). At the typical €40–€300 accessory price point common in the EU market, 15% means roughly €6–€45 off per item — and on a multi-item Model Y or Juniper outfitting order, that scales fast.
| Order value | You pay | You save |
|---|---|---|
| €50 | €42.50 | €7.50 |
| €100 | €85.00 | €15.00 |
| €250 | €212.50 | €37.50 |
| €500 (full kit) | €425.00 | €75.00 |
Why HAMPHI is different from other 15% Tesla codes
Two stores in our index now offer a verified 15% code: HAMPHI's FREDRIK and TESMAG's AWD. The headline number is the same, but the businesses behind the codes are not. TESMAG is a Tesla-accessory storefront that sources from manufacturers (largely in China) and dropships globally — that volume model is what allows a 15% margin on the affiliate side, but it also means 10–20-day transit and email-only customer service. HAMPHI works the opposite way: it imports and curates a smaller catalog, stocks it in Sweden, and ships from EU warehouses with tracked couriers. You're paying European retail prices, but the 15% brings them in line with the dropship competition while keeping the shipping speed and warranty handling that EU buyers expect.
If you're in the EU or UK and value delivery in days over the absolute lowest sticker price, HAMPHI is the better fit. If you're outside Europe and shipping cost is the deciding factor, TESMAG's AWD code may net out closer.

HAMPHI isn't the right store for you if…
- You're shopping for a Tesla camping mattress. HAMPHI carries camping organizers and road-trip storage, but not the fitted-foam Model Y/3 mattresses we review on this site — see our Snuuzu, Havnby, or NovaPads codes instead.
- You want the cheapest possible aero caps or generic interior trim. HAMPHI prices reflect EU-warehoused, curated stock — for the absolute bottom of the price ladder, a dropshipper like TESMAG (with the AWD code) will undercut on the raw sticker even after both codes apply.
- You're shipping to North America or Asia. HAMPHI does ship outside the EU, but transit time and shipping cost erode the 15% advantage. EU and UK buyers see the strongest savings.
- You need an item that's not in HAMPHI's curated catalog. The store keeps its SKU count tight — that's why QC and stock reliability are strong, but it also means very niche parts may need to come from a broader catalog like TESMAG or a brand-direct store.
HAMPHI shipping, returns and the EU advantage
HAMPHI ships from Borås, Sweden. EU orders typically arrive in 2–5 business days via tracked couriers; UK and Nordic deliveries are at the fast end of that range. Returns follow standard EU consumer law (14-day right of withdrawal on online orders), and warranty handling is done first-party rather than passed back to a Chinese manufacturer — which is the practical difference customers notice if something arrives damaged or fails after a few months. HAMPHI also runs a physical store and workshop in Borås and Gothenburg, so EU customers have a real address to escalate to if needed.
For Tesla owners who've previously been burned by dropship transit times or no-reply customer service, HAMPHI's setup is the practical upgrade. The 15% FREDRIK code makes the EU-pricing premium effectively disappear.
Step-by-step: how to redeem the FREDRIK code
- Open hamphi.com and pick the right storefront (en, en-eu, en-us) for your region — the catalog and shipping options adjust automatically.
- Filter by Tesla model — Model Y (including the 2026 Juniper refresh), Model 3, Model S, Model X. HAMPHI's fit data is accurate per model year, so wrong-fit risk is low.
- Add items to cart. Roof racks, custom rubber mats, S3XY buttons and cargo grids are HAMPHI's most-reviewed categories.
- At the cart page, enter FREDRIK in the discount code field. The 15% reduction shows immediately on the cart subtotal.
- Proceed to checkout and confirm the discount carries through to the final total before paying.
- Save the order confirmation email — HAMPHI's tracking numbers post within 24 hours of dispatch.

HAMPHI for Tesla Model Y Juniper buyers
HAMPHI is one of the first EU stores to publish a dedicated Model Y Juniper accessory collection, with fit data updated for the 2026 refresh. For new Juniper owners specifically, the FREDRIK code is the easiest way to outfit the car at launch — mats, sun shades, roof rails and storage in a single order, with the 15% taking the bite out of the curated-EU pricing.
Frequently asked questions
What is the HAMPHI discount code for 2026?
The code is FREDRIK and it takes 15% off your subtotal at hamphi.com. Enter it in the discount code field at checkout.
How does HAMPHI compare to TESMAG or Havnby?
HAMPHI and TESMAG both run 15% codes (FREDRIK and AWD respectively), but HAMPHI ships from Sweden in 2–5 days within the EU, while TESMAG ships from China in 10–20 days. Havnby (code at 10%) is mattress-focused and not directly comparable. For EU buyers, HAMPHI is the speed-and-warranty pick; TESMAG is the lowest-headline-price pick for buyers who can wait.
Does HAMPHI ship outside the EU?
Yes — HAMPHI ships globally, but the 2–5 day delivery window applies to EU and UK addresses. North American and Asian orders take longer and pay higher shipping, which narrows the 15% advantage. EU/UK is where FREDRIK is most worth using.
Is HAMPHI legit?
Yes. HAMPHI operates a registered Swedish business with a physical warehouse and store in Borås, a workshop in Gothenburg, and active social presence on Instagram (@hamphi.se) and Facebook. Returns follow EU consumer law (14-day right of withdrawal), and the company is reachable by phone and email — a meaningful contrast to email-only dropship competitors.
Does FREDRIK work on already-discounted items?
FREDRIK applies to the cart subtotal. On items already in a HAMPHI sale promotion, the code typically stacks on the sale price, but specific seasonal campaigns occasionally exclude — the discount line on the cart will show whether it applied before you pay.
Is there a minimum order for the 15% discount?
No minimum. FREDRIK applies to any subtotal, so it's worth using even on a single mat or S3XY-button order.
Does HAMPHI sell Tesla spare parts as well as accessories?
Yes — HAMPHI runs a separate OEM spare-parts portal at spareparts.hamphi.com for genuine Tesla parts. The FREDRIK code is verified for the main accessories site; for the spare-parts portal, check the cart at checkout to confirm.
Why this code matters for HAMPHI buyers
At 15%, FREDRIK is tied for the highest-percentage Tesla-accessory code we've verified — and it's the only 15% code attached to an EU-warehoused retailer. For Model Y, Model Y Juniper, Model 3, Model S and Model X owners in the EU and UK, that means dropship-level savings without the dropship trade-offs: tracked 2–5 day shipping, EU consumer-law returns, real customer service, and curated stock that's been pre-filtered for fit and quality. On a €500 outfitting order — mats, roof rails, S3XY buttons, organizers — that's €75 off and the package on your driveway inside a week. The math is hard to beat in the European Tesla market right now.
